Slab Leak Detection & Repair in Newnan, GA

How Slab Leak Detection & Repair Works in Newnan

Slab leak repair in Newnan follows a two-phase model: first we pinpoint the exact leak location without unnecessary concrete breaking, then we recommend the most cost-effective repair method based on what we find. This detection-first approach prevents the costly mistake of jackhammering the wrong section of your floor, which can happen when contractors skip proper detection and rely on guesswork. For Newnan homeowners, where red clay soil and copper pipe corrosion create unique challenges, accurate detection saves both money and disruption time.

The entire process—from your first call to completed repair—typically takes 1-3 days for straightforward repairs, or up to 2 weeks for extensive work requiring concrete curing. We'll walk you through both phases so you know exactly what to expect.

Phase 1: Pinpointing the Leak Location

Detection happens first because knowing the exact leak location—within 1-2 feet—allows us to choose the least invasive, most cost-effective repair method. In Newnan homes, we select from four primary detection methods based on your symptoms, foundation type, and pipe material.

Electronic leak detection uses electromagnetic pipe locators and ground microphones to trace your water lines and identify leak sounds through your concrete slab. This works exceptionally well for copper and PEX pipes in slab-on-grade foundations common in newer Newnan developments. We pressurize your system, scan with specialized equipment, and mark the exact location on your floor. This method handles most residential detections in 1-2 hours and costs $300-500 for average-sized homes.

Acoustic leak detection listens for the specific frequency of water escaping under pressure, using sound amplification equipment that filters out background noise. We use this method for homes with thicker slabs, post-tension foundations in some Newnan subdivisions, or when electronic detection needs confirmation. Georgia's dense red clay soil can dampen sound transmission, requiring us to take multiple readings and triangulate the leak position. This process takes 2-3 hours and costs $400-600 depending on home complexity.

Thermal imaging detection uses infrared cameras to identify temperature differences caused by hot water leaks. If you've reported a warm spot on your floor, we scan the area to visualize the thermal signature of escaping hot water. This non-invasive method works through carpet, tile, and hardwood without disturbing your flooring. However, it only detects hot water line leaks—not cold water—and requires sufficient temperature contrast to be effective. Thermal imaging takes about 1 hour and costs $500-700, often combined with electronic detection for comprehensive assessment.

Pressure testing confirms whether a leak exists before we deploy more expensive detection methods. We close your system, pressurize it to a controlled level, and monitor for pressure drops over 30-60 minutes. A confirmed pressure loss tells us a leak is present somewhere in the system. We also use video pipe inspection—threading a camera through cleanouts to assess overall pipe condition—when multiple leaks are suspected or when we need to evaluate whether partial repair or whole-house repiping makes more sense for aging systems. Pressure testing costs $250-400; video inspection adds $300-500.

In Newnan homes, detection method choice depends on your foundation type (slab-on-grade vs. older pier-and-beam in historic districts), pipe material (copper pipes in homes built 1970s-1990s vs. PEX in newer construction), and Georgia's clay soil conditions that affect acoustic transmission. After detection, you'll see the marked leak location, receive photo documentation, and get a clear assessment of pipe condition around the leak—information that guides the repair decision.

Phase 2: Repair Method Selection

Once we've located your leak, we explain your repair options and help you choose the method that fits your priorities: minimizing disruption, preserving flooring, managing budget, or preventing future leaks. The method we recommend depends on leak location (accessible vs. under finished floors), pipe condition (isolated leak vs. widespread corrosion), your home's access characteristics (attic availability for rerouting, exterior access for tunneling), and your long-term plans for the property.

Trenchless epoxy pipe lining creates a permanent seal without breaking concrete—ideal when you want to preserve tile, hardwood, or specialty flooring common in Newnan's historic district homes. This costs $2,000-5,000 depending on line length and typically completes in 1-2 days. We use this when the leak is in an accessible pipe section and the surrounding pipe has sufficient wall thickness (not severely corroded throughout).

Copper-to-PEX repiping reroutes plumbing above your slab through attics or crawlspaces, eliminating future under-slab leak risk entirely. Many Newnan homeowners with homes built in the 1980s-1990s choose whole-house repiping ($6,000-12,000, completed in 3-5 days) when they discover their copper pipes are corroding systemwide—not just at one leak point. Partial rerouting of the affected line costs $4,000-8,000 and takes 2-3 days.

Tunneling under your foundation preserves interior flooring by hand-digging exterior access to the leak point. In Newnan's clay soil, tunneling is physically demanding but creates stable, shore-able tunnels. This method costs $3,000-7,000 depending on distance and takes 3-5 days. We recommend tunneling when your leak is within 15 feet of your foundation perimeter and you want to avoid interior demolition.

Spot repair with concrete restoration directly accesses the leak by removing a 2x3-foot section of concrete, repairing the pipe, and pouring new concrete. This costs $1,500-3,500 including floor restoration and takes 2-3 days for plumbing work plus 1-2 weeks for concrete curing before full weight-bearing use. This method works well for garage slab leaks or utility area leaks where finished flooring isn't a concern.

Rerouting plumbing around the leak installs new pipe above your slab, bypassing the damaged section entirely. This is the fastest option (4-8 hours, same-day service) at $800-2,500 depending on routing complexity. We route new PEX lines through your attic (most Newnan homes have attic access), insulate per Georgia code, and leave the old under-slab section depressurized but in place.

The right method depends on your specific situation: whether you're dealing with an isolated leak or aging pipes throughout, whether you value speed or long-term prevention, and how Newnan's slab-on-grade foundations and clay soil conditions affect access and costs. We present all viable options with transparent cost ranges, timeline expectations, and pros/cons so you can make an informed decision. Once you approve a method, we handle any required Coweta County permits, schedule the work, and complete repairs with minimal disruption to your daily routine.

Slab Leak Detection Methods for Newnan Homes

Detecting a slab leak without breaking concrete in the wrong spot requires specialized equipment and trained expertise. In Newnan, where red clay soil and copper pipe corrosion create complex detection scenarios, we use multiple methods—often in combination—to pinpoint leaks within 1-2 feet before any demolition begins. The detection method we choose depends on your home's pipe materials, foundation type, symptom patterns, and the nature of the leak itself.

Electronic Leak Detection in Newnan

Electronic leak detection uses electromagnetic pipe locators combined with ground microphones to pinpoint pressurized water leaks beneath concrete slabs. The process works by pressurizing your water lines (after isolating the leaking section), then sweeping the floor with an electromagnetic field detector that traces pipe routing while listening for the acoustic signature of escaping water. When water exits a pipe under pressure, it creates a distinct frequency—typically 400-600 Hz for copper pipes—that ground microphones amplify through concrete.

How we perform electronic detection in your Newnan home: We shut off your water supply, attach pressurization equipment to accessible pipe ends (usually at the water heater or main shutoff), and pressurize the system to 80-100 PSI. While one technician scans the floor with the electromagnetic locator to map pipe routes, another uses sensitive ground microphones at suspected leak areas. The microphone detects the high-frequency hissing sound of water escaping under pressure. By cross-referencing pipe location with acoustic signals, we mark the exact leak spot—typically within 12-18 inches—before any concrete is touched. The entire process takes 1-2 hours for an average Newnan home.

Best use cases: Electronic detection excels for copper and PEX supply line leaks in slab-on-grade foundations common in Newnan's newer developments built from the 1990s onward. It works best when we can isolate and pressurize the leaking line section, which requires accessible shutoff valves or cleanouts. For homes with multiple potential leak points, electronic detection quickly eliminates zones without leaks, narrowing our focus before deploying more time-intensive methods.

Newnan-specific application: Electronic detection performs reliably in Newnan's slab-on-grade homes, especially those built after 1985 when copper became standard. However, Georgia's dense red clay soil can dampen acoustic signals, requiring us to place microphones at closer intervals than we would in sandy or rocky soil. Homes in Newnan's six historic districts—with older pier-and-beam foundations or hand-poured slabs—may lack the uniform concrete density needed for clear electromagnetic field mapping, making acoustic detection a better first choice for these properties.

Accuracy and limitations: Electronic detection pinpoints leaks within 1-2 feet horizontally, which translates to a 2x3 foot concrete opening for most repairs. Accuracy depends on soil moisture (saturated clay conducts sound differently than dry clay), concrete thickness (6-inch slabs yield clearer signals than 4-inch), and pipe depth (pipes deeper than 18 inches produce weaker acoustic signals). Electronic detection cannot locate drain leaks because drains aren't pressurized, and it struggles with very slow leaks that don't produce enough acoustic signature to detect through concrete.

Timeline: 1-2 hours for detection in homes up to 2,500 square feet. Larger homes or properties with complex pipe routing may take 3 hours.

Cost range in Newnan: $300-$600 for straightforward single-leak detection. Cost increases to $600-$800 for homes with multiple suspected leak areas or difficult access requiring pressure isolation of several line sections. We include photos of marked leak locations and written documentation of our findings.

When we recommend electronic detection: Electronic detection is our first-line method for Newnan homes built 1980s-present with copper pipes under accessible slabs, when you've noticed symptoms like water meter spinning or isolated hot floor spots indicating a single leak location. For homes with post-tension cable foundations (common in some Newnan developments from the 2000s), we combine electronic with acoustic methods because post-tension cables interfere with electromagnetic field reading.

Acoustic Leak Detection for Deep Foundations

Acoustic leak detection uses ground microphones and vibration sensors to listen for the sound of water escaping pressurized pipes beneath concrete. Unlike electronic detection, which relies on electromagnetic pipe tracing, acoustic detection focuses purely on sound amplification—making it effective for deep slabs, thick concrete, and foundations where electromagnetic signals are unreliable. The equipment amplifies frequencies between 100-1000 Hz, the range where pressurized water leaks produce the most distinct sound signatures.

Technology and process: We pressurize your water system to operating pressure (typically 60-80 PSI for Newnan municipal water), then systematically scan your floor with acoustic sensors in a grid pattern. Each sensor placement captures ambient sound for 30-60 seconds while our equipment filters out background noise (HVAC, appliances, traffic) to isolate leak-specific frequencies. When a leak is present, the sensor closest to it registers the highest amplitude reading. By taking measurements at multiple points, we triangulate the exact leak location—similar to how seismologists locate earthquake epicenters. In Newnan homes with red clay soil, we often need to take readings at 4-6 foot intervals because clay's density dampens sound more than sandy or rocky soils.

Best use cases: Acoustic detection is our method of choice for post-tension slab foundations, which became common in some Newnan subdivisions built 2000-2010. Post-tension cables (steel cables tensioned through the slab for strength) create electromagnetic interference that renders electronic detection less accurate. Acoustic detection also works well for leaks deeper than 2 feet below the slab surface—situations where electronic signals weaken but acoustic waves still propagate clearly. For Newnan's older homes (pre-1980) with hand-poured slabs of inconsistent thickness, acoustic methods avoid the signal distortion that uneven concrete creates for electromagnetic detection.

Newnan soil and foundation considerations: Georgia red clay is dense and moisture-retentive, which affects acoustic detection in two ways. First, saturated clay transmits sound waves more uniformly than dry clay, making detection slightly more accurate during wet months (typically late winter through spring). Second, clay's density requires closer sensor spacing—we use 4-6 foot intervals in Newnan versus 8-10 foot intervals in sandy coastal areas. For homes in Newnan's historic districts with pier-and-beam foundations or crawlspace access, we can often place acoustic sensors directly on exposed pipes, which dramatically improves accuracy and eliminates concrete as a sound barrier.

Accuracy and timeline: Acoustic detection typically pinpoints leaks within 2-3 feet, which means a slightly larger concrete opening than electronic detection but still far better than exploratory demolition. The process takes 2-3 hours for an average Newnan home, longer if we're triangulating multiple potential leak points. Accuracy decreases if your home has significant ambient noise (busy roads, nearby construction, loud HVAC systems) or if the leak flow rate is very slow (less than 0.5 gallons per minute)—slow leaks don't produce enough acoustic energy to detect reliably through concrete and clay.

Cost range: $400-$700 for single-leak acoustic detection in Newnan. Costs reach $800-$900 for complex cases requiring multiple sensor grid passes or when we combine acoustic with electronic methods to confirm findings. We provide written reports with sensor amplitude readings and marked floor locations.

When we recommend acoustic detection: We use acoustic as the primary method for Newnan homes with post-tension slabs, thick concrete (over 6 inches), or when electronic detection has failed to produce clear results. It's also our choice for leak detection in crawlspace areas where we can access exposed pipes—common in Newnan's older homes with pier-and-beam foundations. For homeowners who've had inconclusive results from other detection companies, acoustic often succeeds by approaching the problem from a purely sound-based perspective rather than relying on electromagnetic field mapping.

Thermal Imaging Leak Detection

Thermal imaging leak detection uses infrared cameras to identify temperature variations on floor surfaces caused by hot water leaking beneath slabs. The technology works on a simple principle: hot water escaping from a pressurized line creates a thermal signature—a measurably warmer area—that shows up clearly on thermal imaging cameras as a color contrast against surrounding floor temperatures. This method is completely non-invasive and can scan large floor areas quickly, making it valuable for initial leak location screening in Newnan homes.

How thermal imaging works: We use FLIR (Forward Looking Infrared) cameras that detect infrared radiation in the 7-14 micrometer wavelength—the range where temperature differences from hot water leaks are most visible. The camera displays real-time thermal maps of your floor, with warmer areas appearing as red/orange and cooler areas as blue/purple. A hot water slab leak typically shows up as a distinct warm spot measuring 80-95°F surface temperature when the surrounding concrete floor sits at 65-75°F. We scan your entire living area systematically, photographing thermal anomalies and correlating them with known pipe routing and your symptom descriptions (where you've felt warm spots, where water bills increased, etc.).

Best use cases and limitations: Thermal imaging only detects hot water leaks—it cannot identify cold water supply leaks or drain leaks because they don't create measurable temperature differences. In Newnan, where copper hot water lines are common in homes built 1970s-2000s, thermal imaging excels for detecting water heater main line leaks, recirculation loop failures, and hot water supply lines to kitchen/bath fixtures. The method works best during cooler months (fall through spring) when the temperature contrast between leaked hot water and ambient floor temperature is greatest. During Georgia summers when floor surfaces naturally warm from heat transfer, thermal imaging becomes less reliable because the temperature differential diminishes.

Process and limitations: We typically perform thermal scans early morning or evening when floor temperatures have stabilized and aren't influenced by direct sunlight, foot traffic, or HVAC activity. Carpet, thick padding, and some flooring materials (cork, thick vinyl) can insulate thermal signatures, reducing detection accuracy. Tile and bare concrete provide the clearest thermal readings. In Newnan homes with radiant floor heating systems (rare but present in some newer custom homes), thermal imaging produces too much thermal noise to reliably identify leaks—acoustic or electronic detection is required instead.

Newnan-specific application: Most Newnan homes don't have radiant floors, making thermal imaging a viable screening tool for hot water leak suspicion. However, Georgia's red clay soil retains heat when saturated with hot water, which can spread the thermal signature over a wider area—what should appear as a 2-foot diameter hot spot might show as a 4-6 foot diffuse warm area. This soil heat retention means thermal imaging identifies the general leak zone but typically requires follow-up with acoustic or electronic detection to pinpoint the exact spot before concrete breaking.

Timeline and accuracy: Thermal scanning takes 45-90 minutes for a typical Newnan home, including time to photograph findings and correlate with pipe routing. The method identifies leak zones within 3-5 feet but rarely achieves the 1-2 foot precision of acoustic or electronic detection. We use thermal imaging as a screening tool to quickly rule out large floor areas without leaks, then deploy more precise methods in confirmed zones.

Cost in Newnan: $500-$800 as a standalone detection method. We often include thermal imaging at no extra charge when combined with electronic or acoustic detection because it speeds the overall process by narrowing our search area before deploying time-intensive equipment.

When we recommend thermal imaging: Thermal imaging is valuable when you've reported a warm or hot spot on your floor but aren't sure of the exact location, when you want to screen your entire home for potential hot water leaks before selling or as preventive maintenance, or as a first step before acoustic/electronic detection in large homes where scanning every area with ground microphones would take excessive time. For cold water leaks, thermal imaging provides no value—we proceed directly to acoustic or electronic methods.

Pressure Testing & Video Pipe Inspection

Pressure testing and video pipe inspection serve different purposes than acoustic or electronic detection—they assess your plumbing system's overall condition and confirm leak existence before investing in pinpoint detection. In Newnan, where copper pipe corrosion and aging systems are common, these diagnostic tools often reveal system-wide problems that change our repair recommendation from single-leak spot repair to whole-house repiping.

Static pressure testing protocol: We isolate your home's water supply system by closing the main shutoff valve, attach a pressure gauge and air compressor to a convenient access point (usually the water heater drain or an outdoor hose bib), and pressurize the system to 100-120 PSI—higher than normal operating pressure but within safe limits for copper and PEX piping. We then monitor pressure for 15-30 minutes. A system without leaks maintains pressure with minimal drop (less than 5 PSI over 30 minutes). A system with active slab leaks shows steady pressure decline—the faster the decline, the larger or more numerous the leaks. This test definitively confirms leak existence and approximate severity before spending money on pinpoint detection equipment.

What pressure testing reveals: For Newnan homeowners concerned about one leak but potentially facing multiple issues, pressure testing provides crucial decision-making information. If your system loses 20+ PSI in 15 minutes, you likely have multiple leaks or one large leak. This finding often changes the repair strategy from spot repair to whole-house repiping, saving you from repairing one leak only to face another six months later. Pressure testing also identifies leaks in areas where symptoms haven't appeared yet—a leak under a garage slab might not show obvious signs like a living area leak would, but the pressure test reveals its presence.

Video pipe inspection process: We insert a waterproof camera attached to a flexible cable through existing cleanouts (typically located in bathroom walls, kitchen sink areas, or exterior access panels) and navigate through your drain and supply lines, recording video of pipe interiors. The camera shows us corrosion patterns, mineral buildup scale, pipe joint condition, and actual pinhole leak locations if the leak is large enough to see visually. In Newnan homes with copper pipes installed 1970s-1990s, video inspection often reveals pitting corrosion throughout the system—dozens of weak spots that haven't failed yet but will within 2-5 years. This visual evidence helps homeowners understand why we're recommending repiping instead of spot repair.

Best use cases in Newnan: We recommend pressure testing plus video inspection for homes over 25 years old with original copper plumbing, when you've already had one slab leak repaired and want to assess system-wide condition before deciding on further repairs, or when you're experiencing multiple symptoms (high bills plus low pressure plus intermittent warm spots) that suggest multiple leaks. For homes with polybutylene plumbing—common in Newnan properties built 1978-1995—video inspection shows whether the gray plastic pipes are showing stress cracking or joint failure that requires immediate whole-house repiping before catastrophic failures occur.

Limitations: Video inspection only accesses pipes with cleanouts or accessible ends—we can't camera inside sealed under-slab sections without creating access points. The camera shows interior pipe condition but can't see the exterior of pipes where soil-contact corrosion occurs. Pressure testing confirms leak existence but doesn't pinpoint location—it's a diagnostic tool that precedes pinpoint detection, not a replacement for it.

Timeline and cost: Pressure testing takes 30-60 minutes including setup and monitoring time. Video inspection takes 1-2 hours depending on how many pipe sections we're examining and whether we need to remove access panels to reach cleanouts. In Newnan, we charge $250-$450 for comprehensive pressure testing and $400-$700 for video inspection. When combined with pinpoint detection service, we often discount these diagnostic tools because they streamline the overall process.

When we recommend pressure testing and video inspection: We recommend this combination when symptoms suggest system-wide issues rather than isolated leaks, when your home is in the age range where copper corrosion is statistically likely (20-40 years old), before purchasing an older Newnan home (pre-1995) to assess plumbing condition, or when you're planning long-term ownership and want to make informed repair-versus-repipe decisions based on actual pipe condition rather than guesswork. These tools turn plumbing assessment from speculation into evidence-based decision-making.

Slab Leak Repair Options Compared

Once we've detected your slab leak, the repair decision depends on leak location, your home's foundation type, pipe condition, your floor finishes, and your long-term ownership plans. In Newnan, where red clay soil movement and copper corrosion are primary leak causes, the repair method we recommend must address not just the immediate leak but the underlying system vulnerability. Here's how each repair approach works, when it makes sense, and what it costs in Coweta County.

Trenchless Epoxy Pipe Lining

Trenchless epoxy pipe lining creates a new pipe inside your existing copper or galvanized pipe without excavation or concrete demolition. The process involves cleaning the pipe interior with high-pressure water jetting to remove corrosion, scale, and debris, then coating the interior with food-grade epoxy resin that cures in place to form a smooth, sealed barrier. The result is essentially a pipe-within-a-pipe that restores structural integrity and stops leaks permanently—all through existing access points like water heater connections or outdoor hose bibs.

Detailed process: After detecting and marking your leak location, we access both ends of the affected pipe section (typically a hot water main line from the water heater to the kitchen/bathroom area). We use specialized hydrojetting equipment to scour the pipe interior, removing 30-40 years of accumulated mineral deposits and corrosion. Once clean, we dry the pipe with compressed air, then pull a resin-saturated liner through the pipe using cable systems. The epoxy cures through ambient heat or UV light activation (depending on the system) for 4-6 hours, bonding to the pipe interior and sealing pinhole leaks, cracks, and corroded sections. After curing, we pressure test the lined section to 150 PSI per Georgia plumbing code, flush the system, and restore water service.

Best use cases in Newnan: Epoxy lining works best for single-section leaks in homes where floor preservation is the priority—Newnan properties with hardwood floors, custom tile work, or finished living areas where concrete demolition would require expensive restoration. The method excels for hot water main lines (the 40-60 foot run from water heater to kitchen/bath areas that fails first due to hot water's accelerated corrosion effect) and for homes where the rest of the plumbing system is sound. It's ideal for homeowners who want permanent repair without the disruption of jackhammering or the cost of whole-house repiping.

Newnan-specific application: Epoxy lining works well in Newnan's slab-on-grade homes common in developments built 1985-2010, where pipe routing is relatively straightforward and access points are available. Historic district homes with pier-and-beam foundations or crawlspace access are excellent candidates because we can often access pipes from below rather than through concrete. The method performs reliably in Coweta County's clay soil conditions because the epoxy liner eliminates exterior pipe exposure to corrosive soil contact—the clay can't reach the pipe anymore. However, homes with severely corroded pipes (less than 40% wall thickness remaining) aren't candidates because the epoxy needs adequate pipe structure to bond to.

Advantages: No concrete breaking means no floor restoration costs, no demolition mess, and no furniture moving. Completion time is 1-2 days from detection to restored water service. The epoxy creates a smoother pipe interior than corroded copper, often improving water pressure. Lifetime warranty coverage on lined sections provides long-term peace of mind. For Newnan homeowners with finished basements or high-value flooring, epoxy lining's floor-preservation benefit often justifies its higher cost compared to spot repair.

Limitations and tradeoffs: Epoxy lining requires accessible pipe ends—we need cleanouts, shutoff valves, or water heater connections at both ends of the affected section. Homes without these access points need them created first, adding cost. The method only addresses the specific pipe section we line—if your home has multiple weak points (common in systems over 30 years old), you might face additional leaks in unlined sections within 2-5 years. Epoxy slightly reduces interior pipe diameter (typically 3-5%), which rarely affects performance in residential applications but is worth knowing. The process requires water shutoff for 6-8 hours during application and curing.

Process timeline in detail: Day 1 morning: We begin hydrojetting the affected pipe section, which takes 2-3 hours depending on corrosion severity. Day 1 afternoon: We pull the epoxy liner through the cleaned pipe and begin curing process (4-6 hours). Overnight: Epoxy completes curing. Day 2 morning: We pressure test the lined section, flush your system to remove any curing byproducts, and restore full water service. Total elapsed time: 24-36 hours, with water service restored by end of Day 2.

Newnan cost factors: Epoxy lining in Newnan runs $2,500-$4,500 for typical hot water main line repairs (40-60 feet of pipe). Cost increases to $5,000-$7,000 for longer runs or when we're lining cold water mains in addition to hot water lines. Factors affecting cost include pipe length, number of access points requiring creation, pipe condition (heavily corroded pipes take longer to clean), and whether we're lining a single section or multiple sections. These prices include detection, epoxy materials, labor, pressure testing, and warranty documentation—no separate floor restoration cost because no concrete is broken.

Warranty coverage: We provide lifetime warranty against leaks in epoxy-lined sections. The epoxy resin itself carries a 50-year manufacturer warranty against degradation. If a lined section develops a leak during your ownership, we re-line at no charge. Warranty is transferable to future homeowners, which helps with home resale value.

When we recommend epoxy lining: This method is our first choice for Newnan homeowners who have high-value finished floors (hardwood, custom tile, specialty flooring), when the leak is in a main hot water line and the rest of the system appears sound based on pressure testing and age, when homeowners want permanent repair without demolition disruption, and when the home is under 35 years old with pipe wall thickness adequate for epoxy bonding. We don't recommend it for homes with system-wide corrosion (pressure tests showing multiple weak points) or when pipes are so corroded that epoxy has insufficient structure to bond to—in those cases, repiping provides better long-term value.

Copper to PEX Repiping

Copper to PEX repiping eliminates under-slab pipes entirely by installing new cross-linked polyethylene (PEX) supply lines routed through attics, crawlspaces, or along exterior walls, then abandoning the leaking under-slab sections in place. This approach permanently solves slab leak problems because it removes pipes from beneath the concrete where they're vulnerable to soil corrosion and foundation movement. PEX piping is flexible, freeze-resistant, corrosion-proof, and carries a 25-year manufacturer warranty—making it the gold standard for whole-house repiping in Newnan's challenging soil conditions.

How PEX repiping works: We install a central PEX manifold (distribution hub) near your water heater or main water entry point, then run dedicated PEX lines to each fixture through accessible routes. Unlike copper's rigid branching system where one pipe feeds multiple fixtures (creating pressure drops and complex routing), PEX uses a home-run system—each fixture gets its own dedicated line from the manifold. This design improves water pressure, allows individual fixture shutoff at the manifold for future repairs, and eliminates the complex under-slab routing that makes copper systems vulnerable. In Newnan homes, we typically route PEX through attic spaces (for single-story homes) or between-floor spaces (for two-story homes), using insulation to protect against temperature extremes.

Reroute versus whole-house repipe: A reroute addresses only the leaking section—we install new PEX from the manifold to the affected area (kitchen, master bath, etc.), bypassing the under-slab leak while leaving the rest of the copper system active. Whole-house repiping replaces all supply lines, eliminating both current and future under-slab leak risk. In Newnan, we recommend rerouting for isolated leaks in homes under 20 years old where the rest of the system tests sound. We recommend whole-house repiping for homes 25+ years old with copper pipes, homes that have had multiple slab leaks, or when pressure testing reveals system-wide weak points that will fail within 2-5 years.

Best use cases for Newnan homes: PEX repiping makes sense when you've had multiple slab leaks (indicating system-wide copper failure), when your home is 25+ years old with original copper plumbing and you're planning long-term ownership, when pressure testing shows low remaining pipe wall thickness throughout the system, or when you want to eliminate future under-slab leak risk entirely. It's also the right choice for homes with polybutylene piping—common in Newnan properties built 1978-1995—because polybutylene is prone to catastrophic failure and should be replaced proactively. For homeowners planning kitchen or bathroom remodels, coordinating repiping with remodel work makes sense because walls are already open for access.

Newnan-specific application and routing: Single-story homes in Newnan's newer subdivisions (1990s-present) typically have accessible attics, making PEX routing straightforward—we run lines through the attic space and drop down through walls to fixtures. Homes in Newnan's historic districts often have crawlspace access or accessible pier-and-beam foundations, allowing us to route PEX below the house without attic work. Two-story homes require routing through interstitial spaces between floors, which may involve minimal drywall patching at access points. Georgia's building code requires PEX in attic spaces to be insulated to prevent freeze damage during rare hard freezes (Newnan sees temperatures below 20°F roughly once every 2-3 winters) and to prevent hot water temperature loss during summer when attic temps reach 130-140°F.

Advantages over copper repair: PEX repiping provides lifetime elimination of under-slab leak risk—you'll never face another slab leak because there are no more pipes under your slab. Water pressure typically improves because PEX's smooth interior creates less friction than corroded copper, and the home-run manifold system delivers dedicated pressure to each fixture. Individual fixture shutoff at the manifold means future repairs (replacing a bathroom faucet, fixing a toilet supply line) require no whole-house water shutoff. PEX resists Georgia's aggressive water chemistry that corrodes copper—no mineral buildup, no pinhole corrosion. Installation is faster than copper soldering because PEX uses mechanical connections (crimp rings or expansion fittings) that don't require torch work or solder joints. Future access is easier—if you ever need to modify plumbing for a remodel, PEX adapts easily without cutting and soldering.

Limitations and honest tradeoffs: PEX repiping costs more upfront than spot repair or epoxy lining—you're paying for system-wide replacement rather than fixing one leak. Some pipe routing will be visible in attics, closets, or along exterior walls (we conceal with soffit boxes or wall chases where possible, but complete concealment isn't always feasible). The installation process is more disruptive than trenchless methods—water service is off for 1-2 days while we complete connections, and we need access to walls for drops to fixtures (minimal drywall patching required). Homes with heavily finished attics (converted to living space) or homes without attic access face higher routing complexity and cost. Despite these tradeoffs, whole-house PEX repiping provides the highest long-term value for Newnan homes with aging copper systems because it solves the problem permanently rather than treating symptoms.

Process walkthrough: Day 1: We install the PEX manifold near your water heater and begin routing main supply lines through attic/crawlspace to major areas (kitchen, master bath, laundry). We drill small holes through top plates to drop lines down walls to fixtures. Day 2-3: We complete individual fixture connections, connect hot and cold supply lines to each faucet, toilet, shower, water heater, ice maker, hose bibs, and appliances. Day 3-4: We pressure test the entire system to 150 PSI per Georgia code, flush all lines to remove installation debris, insulate exposed PEX per code requirements, and perform final fixture checks. Day 4-5: We complete drywall patching at wall access points, restore water service, and conduct a walkthrough demonstrating the manifold's individual shutoffs. For whole-house repipes in typical Newnan homes (1,500-2,500 sq ft, 2-3 baths), total timeline is 3-5 days from start to completion.

Newnan and Coweta County code compliance: Georgia plumbing code permits PEX for supply lines (not drain lines). Coweta County requires permits for whole-house repiping ($150-$300 permit fee depending on scope), and completed work must pass inspection by the county Building Inspection Department. We handle all permitting and schedule inspections—you don't need to coordinate with the county. Code requires PEX to be protected from UV light exposure (can't be routed outdoors in direct sunlight), insulated in unconditioned spaces (attics, crawlspaces), and properly secured at maximum 32-inch intervals. We meet or exceed all code requirements and provide documentation for your home records.

Cost in Newnan: Rerouting a single leaking section (kitchen main line, master bath, etc.) costs $4,000-$7,000 depending on routing complexity and distance. Whole-house repiping runs $8,000-$15,000 for typical Newnan homes. Costs vary based on home size (square footage and number of fixtures), routing complexity (single-story with attic access is simplest, two-story or slab-only homes cost more), number of fixtures being served (a 2-bath home costs less than a 4-bath home), accessibility (open attics versus finished attics affect labor time), and whether we're coordinating with other trades during remodels. These prices include PEX materials and fittings (we use Uponor PEX-a, the highest grade), manifold systems, labor, permits, inspections, pressure testing, insulation, and basic drywall patching at access points. No separate detection or floor restoration costs because we're not breaking concrete.

Warranty on materials and installation: PEX tubing carries a 25-year manufacturer warranty against defects and failure. Fittings (crimp rings or expansion fittings) carry the same 25-year coverage. We warranty our installation workmanship for life—if a connection we make develops a leak during your ownership, we repair at no charge. This warranty is transferable to future homeowners, which protects your home's resale value and provides documentation of quality work.

When we recommend PEX repiping: We recommend rerouting (single-section replacement) when you have an isolated leak in a home under 20 years old, when pressure testing shows the rest of the system is sound, when you want to avoid floor demolition but don't need whole-house coverage, or as a temporary solution until you're ready for whole-house repipe. We recommend whole-house repiping when your home is 25+ years old with original copper, when you've had multiple slab leaks indicating system-wide failure, when pressure testing or video inspection shows widespread corrosion or weak spots, when you have polybutylene piping that should be replaced proactively, or when you're planning long-term ownership (10+ years) and want to eliminate under-slab leak risk permanently. For Newnan homes in the 1970s-1990s construction era—the peak of copper under-slab installations—whole-house PEX repiping is often the most cost-effective choice when you calculate avoided future leak repairs, water damage, and foundation impacts over a 10-15 year ownership period.

Tunneling Under Foundation

Tunneling under your foundation provides direct access to leaking under-slab pipes without breaking interior concrete floors—preserving tile, hardwood, carpeting, and finished living spaces. The process involves hand-excavating a horizontal tunnel from an exterior access point (usually along the foundation perimeter where soil meets concrete), shoring the tunnel with plywood or steel supports for safety, accessing the pipe at the leak location, repairing or replacing the damaged section, then backfilling the tunnel with compacted soil. In Newnan, where red clay soil provides stable tunneling conditions and many homes have high-value interior finishes, tunneling offers a floor-preservation alternative to jackhammer spot repair.

Detailed tunneling process: We begin by determining the optimal tunnel entry point based on leak location (marked during detection) and exterior access. In Newnan homes, we typically enter from the foundation perimeter near the leak's interior position—if the leak is under your kitchen 15 feet from the exterior wall, we tunnel 15 feet inward from the nearest exterior access point. We excavate a trench 3-4 feet deep along the foundation exterior to expose the footing, then dig horizontally under the foundation edge. The tunnel dimensions are typically 3 feet wide by 3 feet high—large enough for a technician and tools but minimizing soil disturbance. As we tunnel, we install temporary shoring (plywood sheets supported by adjustable jacks) every 4 feet to prevent collapse—Georgia red clay is stable but code requires shoring for safety. Once we reach the leak location (confirmed by distance measurements and pipe routing), we expose the pipe, cut out the leaking section, install new pipe (copper or PEX depending on system type), pressure test the repair, then backfill the tunnel in 6-inch lifts with compacted clay, restore the exterior grade, and replant any disturbed landscaping.

Best use cases in Newnan: Tunneling makes sense when your leak is under high-value flooring you want to preserve (custom tile, hardwood, specialty finishes), when the leak location is within 15 feet of the foundation perimeter (tunneling beyond 15 feet becomes cost-prohibitive due to time and shoring requirements), when you have accessible exterior space for equipment and excavated soil staging, or when interior demolition would disrupt finished living areas during occupied renovations. It's particularly valuable in Newnan's historic district homes where preserving original flooring is a priority for maintaining historical character and resale value.

Newnan soil and access considerations: Georgia red clay provides excellent tunneling conditions—it's cohesive, holds its shape better than sandy or loose soils, and rarely requires extensive shoring beyond code minimums. However, clay's density means hand excavation (which we use under
