Slab Leak Detection & Repair in Sandy Springs, GA

How Slab Leak Detection & Repair Works in Sandy Springs

Slab leak repair in Sandy Springs follows a two-phase model: detection first, then repair. We detect the exact leak location before opening any concrete because breaking exploratory holes costs $500-1,200 per section and risks missing the leak entirely. Once we pinpoint the leak within 1-2 feet and assess pipe condition, we present repair options with cost, timeline, and disruption levels so you make an informed decision. Detection takes 1-3 hours; repair ranges from same-day rerouting to multi-day spot repairs with concrete cure time.

Phase 1: Pinpointing the Leak Location

We choose detection methods based on your home's age, foundation type, symptoms, and pipe materials. Sandy Springs homes built in the 1960s-1970s with copper pipes under slab-on-grade foundations respond well to electronic detection—we pressurize your lines, use electromagnetic pipe locators to trace routing, and ground microphones to amplify leak sounds, marking the exact spot within 1-2 feet. For post-tension foundations common in newer Perimeter Center developments, acoustic detection handles the extra concrete thickness by triangulating sound from multiple sensor placements. If you report a warm floor spot, thermal imaging scans for temperature differentials from hot water leaks, though it won't detect cold water issues.

For homes where symptoms suggest multiple leaks or widespread corrosion—common in 50-60 year old copper systems in Riverside and Mount Vernon Woods—we start with static pressure testing. We close your system, pressurize to 80 PSI, and monitor for pressure drop over 15 minutes to confirm a leak exists before deploying detection equipment. Video pipe inspection through cleanouts shows us interior pipe condition: if we see pitting corrosion throughout, we'll recommend whole-house repiping rather than chasing individual leaks.

Detection cost in Sandy Springs ranges $300-800 for straightforward electronic detection in accessible homes, up to $1,000 for complex layouts requiring combined acoustic and thermal methods. Georgia's red clay soil affects acoustic detection—clay transmits sound differently than sandy soil, so we adjust sensor spacing accordingly. You'll receive marked floor locations, photos showing detection equipment readings, and a written assessment of pipe condition before we discuss repair options.

Phase 2: Repair Method Selection

Once we know the leak's exact location and your pipes' overall condition, we explain repair options from least invasive (trenchless epoxy lining at $2,000-5,000) to most comprehensive (whole-house PEX repipe at $6,000-15,000). Decision factors include leak location—leaks under tile floors favor trenchless methods to preserve flooring; garage leaks allow spot repair with concrete breaking at lower cost. Pipe condition matters: if detection shows isolated leak in otherwise sound pipes, spot repair or epoxy lining makes sense. If video inspection reveals widespread pitting in 50+ year old copper, repiping prevents future failures.

Your priorities shape the recommendation. Homeowners prioritizing minimal disruption choose epoxy lining (1-2 days, no floor demo) or tunneling under the foundation ($3,000-7,000, preserves interior floors). Budget-conscious homeowners in homes with unfinished garage slabs often choose spot repair with jackhammer access ($1,500-3,500 including concrete restoration). Long-term-focused homeowners with aging copper systems choose copper-to-PEX repiping ($4,000-12,000), routing new lines through attic or crawlspace to eliminate all future under-slab leaks permanently.

Sandy Springs' slab-on-grade foundations allow tunneling from the exterior when leaks are within 15 feet of the foundation perimeter—hand-digging through Georgia clay to access pipes without interior demolition. Post-tension foundations require careful planning: we cannot cut post-tension cables, so repair methods must work around the cable grid. Timeline ranges from 4-8 hours for simple rerouting around a single leak to 2-3 days for spot repair (with 1-2 weeks concrete cure before full weight), to 2-5 days for whole-house PEX repipe.

Slab Leak Detection Methods for Sandy Springs Homes

Before we can repair a slab leak, we need to pinpoint its exact location. Breaking exploratory holes in concrete costs $500-1,200 per section and often misses the leak entirely. Non-invasive detection methods locate leaks within 1-2 feet accuracy before any demolition, saving you thousands in unnecessary concrete work and floor restoration. We select detection methods based on your home's pipe material, foundation type, and symptom patterns—mid-century Sandy Springs homes with copper pipes require different approaches than newer PEX installations.

Electronic Leak Detection in Sandy Springs

Electronic leak detection uses electromagnetic pipe locators combined with ground microphones to pinpoint pressurized water leaks beneath your concrete slab. We send a low-voltage signal through your supply lines, then trace the electromagnetic field with a receiver to map pipe routing. Ground microphones amplify the sound of water escaping under pressure—a hissing or rushing noise distinct from household sounds. Where the electromagnetic signal weakens or disappears and acoustic amplification peaks, that's your leak location within 1-2 feet.

Here's what you see during detection: We pressurize your water lines to 80-100 PSI (normal operating pressure), then methodically scan your floors with handheld equipment. We mark pipe routes with chalk or tape, listen at multiple points, and triangulate the leak based on signal strength and acoustic frequency. If your home has accessible pipe ends—cleanouts or shut-off valves—we can attach our equipment directly for maximum accuracy. Detection takes 1-2 hours for a typical Sandy Springs home.

Electronic detection works best for copper and PEX pipes under accessible concrete slabs. It's our first-line method for homes in Riverside, Mount Vernon Woods, and other neighborhoods with mid-century slab-on-grade construction. The method detects pressurized supply line leaks—hot water mains, cold water feeds—but cannot locate drain leaks because drains don't hold pressure.

Sandy Springs Application: Electronic detection is highly effective in Sandy Springs' typical slab-on-grade homes built in the 1960s-1970s with copper supply lines. However, Georgia's red clay soil can dampen electromagnetic signals when saturated with water from a chronic leak. Post-tension slab foundations—common in newer Sandy Springs construction near Perimeter Center—contain steel cables that interfere with electromagnetic detection. In these cases, we switch to acoustic methods or combine both for confirmation.

Accuracy & Limitations: Electronic detection pinpoints leaks within 1-2 feet when soil conditions are favorable. It cannot detect leaks in drain lines because drains don't hold pressure. If your home has extensive under-slab plumbing or multiple potential leak points, we may need acoustic detection for confirmation. Severely corroded pipes with multiple thin spots sometimes give false positives—the equipment detects weak pipe sections, not just active leaks.

Timeline: 1-2 hours for average Sandy Springs home with straightforward layout. Complex homes with multiple plumbing zones or hard-to-access areas may require 2-3 hours. We provide same-day detection in most cases, with emergency slots available within 2-3 hours of your call.

Cost Range in Sandy Springs: $300-800 depending on home size, accessibility, and detection complexity. Homes over 2,500 square feet or with multiple stories cost $600-800. Single-story ranch homes typical in Riverside and Mount Vernon Woods run $300-500. Detection is free when you choose our repair service.

When We Recommend: Electronic detection is our first choice for Sandy Springs homes built 1960s-1980s with copper supply lines under slab-on-grade foundations. If you report a hot floor spot, elevated water bill with no visible leaks, or sound of running water when fixtures are off, this method locates the problem quickly without exploratory demolition. We combine electronic with acoustic detection for complex cases or when initial electronic scans are inconclusive.

Acoustic Leak Detection for Deep Foundations

Acoustic leak detection listens for the sound of water escaping from pressurized pipes beneath your foundation. We use ground microphones with audio amplification and noise-filtering technology to isolate the frequency signature of a leak—typically a hissing or rushing sound distinct from HVAC systems, appliances, or traffic noise. Technicians place sensors at multiple floor locations, compare acoustic intensity, and triangulate the leak based on where the sound is loudest.

The process involves pressurizing your supply lines, then systematically scanning your floors with contact microphones or geophone sensors. We listen for leak-specific frequencies (400-1,200 Hz) and filter out background noise. Acoustic equipment detects water escaping at high velocity through small pipe openings—the sound signature is consistent even through several inches of concrete and compacted soil. We mark the loudest point, verify with secondary sensor placements, and photograph the marked location before presenting repair options.

Best Use Cases: Acoustic detection excels when electronic methods fail or need confirmation. It's the primary choice for post-tension slab foundations common in newer Sandy Springs construction—steel reinforcing cables in post-tension slabs create electromagnetic interference that ruins electronic detection accuracy. Acoustic also works for deep concrete slabs over 6 inches thick, which dampen electromagnetic signals. When multiple leaks are suspected, acoustic detection identifies the most severe one first based on sound intensity.

Sandy Springs Foundation Context: Post-tension slabs are common in Sandy Springs neighborhoods built after 1990, particularly near Perimeter Center and along GA-400 corridor developments. These foundations use high-tension steel cables for structural support, making electromagnetic detection unreliable. Acoustic detection bypasses this limitation because it relies on sound, not electrical signals. Mid-century slab-on-grade homes in Riverside and Mount Vernon Woods rarely have post-tension construction, so electronic detection is usually first-line there.

Acoustic detection also accounts for Georgia's expansive red clay soil. When clay is saturated from a chronic leak, it creates voids and air pockets under your slab. These voids actually amplify leak sounds, making acoustic detection more effective than electronic methods once soil saturation has occurred. During dry periods when clay contracts, acoustic detection maintains accuracy because it's not affected by soil moisture like electromagnetic signals are.

Accuracy & Limitations: Acoustic detection locates leaks within 1-3 feet depending on slab thickness and soil density. It works only on pressurized supply lines—hot water mains, cold water feeds—not on drain leaks. Background noise from HVAC systems, refrigerators, or nearby traffic can interfere with readings, so we often conduct acoustic detection during quiet hours (early morning or late evening). Extremely slow leaks under 0.5 gallons per minute may not produce detectable sound.

Timeline: 2-3 hours for complex layouts or deep foundations. Post-tension slabs require extra time for sensor repositioning and frequency analysis. We schedule acoustic detection when your home is quietest—early morning or evening hours—to minimize background interference.

Cost in Sandy Springs: $400-900 depending on foundation type, home size, and detection complexity. Post-tension slab detection runs $600-900 due to additional time and specialized equipment. Standard slab-on-grade homes cost $400-600. Detection is free when you authorize repair.

When We Recommend: We choose acoustic detection for Sandy Springs homes with post-tension slabs, deep concrete foundations over 6 inches thick, or when electronic detection gives inconclusive results. If you have a confirmed leak (water meter spinning when all water is off) but electronic methods haven't pinpointed it, acoustic is the next step. For homes in City Springs district with newer construction and post-tension foundations, acoustic is often our first-line method.

Thermal Imaging Leak Detection

Thermal imaging uses infrared cameras to detect temperature differences on your floor surfaces caused by hot water leaks beneath the slab. Hot water escaping from a pressurized supply line heats the concrete directly above it, creating a thermal signature 3-10 degrees warmer than surrounding areas. Our infrared cameras visualize these temperature variations as colored heat maps—warmer areas appear red or yellow, cooler areas blue or green. Where we see a distinct hot spot correlating with your plumbing layout, that's your leak location.

How It Works: We scan your floors with handheld infrared cameras calibrated to detect temperature differences as small as 0.5 degrees Fahrenheit. Thermal imaging works through carpet, vinyl, tile, and thin wood flooring—we don't need to remove floor coverings in most cases. We scan in a grid pattern, document temperature readings, and correlate hot spots with known pipe routing (from blueprints or previous plumbing work). The process takes 1 hour for scanning plus analysis time to rule out false positives from radiant heating, sunlight patterns, or appliance heat.

Best Use Cases: Thermal imaging is effective only for hot water line leaks—it cannot detect cold water supply leaks or drain leaks because they don't create temperature differences. It works best when the temperature differential between leaked hot water and surrounding concrete is significant—winter months in Sandy Springs provide ideal conditions because ambient temperatures are lower. Thermal imaging is non-invasive and quick, making it useful for initial screening when homeowners report warm floor spots but aren't certain of leak severity.

Sandy Springs Climate Factors: Georgia's mild winters (average January low 34°F, high 52°F) create moderate temperature contrast for thermal imaging—enough for detection but not as pronounced as colder climates. Summer heat reduces thermal imaging effectiveness because ambient temperatures (July average high 89°F) narrow the temperature gap between leaked hot water and surrounding concrete. We often run hot water through the system for 15-20 minutes before scanning to maximize thermal contrast.

Limitations: Thermal imaging only detects hot water leaks. It cannot locate cold water supply leaks or drain leaks. Floor coverings thicker than 1 inch (thick carpet with padding, engineered hardwood over plywood subfloor) can insulate thermal signatures and reduce accuracy. Radiant floor heating systems create false positives. Direct sunlight warming floors through windows can mask leak signatures. Thermal imaging is a screening tool—we confirm findings with electronic or acoustic detection before recommending concrete demolition.

Timeline: 1 hour floor scanning plus 30 minutes analysis and documentation. If thermal imaging identifies a hot spot, we follow up with electronic or acoustic confirmation the same visit.

Cost Range: $500-1,000 depending on home size and complexity. Thermal imaging is typically combined with electronic or acoustic detection for confirmation, so we bundle pricing. Standalone thermal imaging (without follow-up confirmation) runs $400-600 but rarely leads to immediate repair authorization—homeowners want pinpoint accuracy before breaking concrete.

When We Recommend: Thermal imaging is useful when you report a warm floor spot and want rapid confirmation before authorizing invasive detection methods. It's a first-step screening tool for suspected hot water leaks. We use it to narrow the search area, then follow up with electronic or acoustic detection for pinpoint accuracy. If you have cold water leak symptoms (no warm floor spot, just high water bills or meter spinning), we skip thermal imaging and go directly to electronic or acoustic methods.

Pressure Testing & Video Pipe Inspection

Pressure testing and video inspection are diagnostic tools that confirm leak existence and assess overall pipe condition before we deploy pinpoint detection methods. These processes answer the questions: "Do I have a leak?" and "How bad is my pipe system?" before you invest in location-specific detection.

Static Pressure Test: We close all fixtures and appliances, pressurize your water supply system to 100 PSI, then monitor pressure over 15-30 minutes. If pressure drops more than 5 PSI, you have an active leak somewhere in the system. The rate of pressure loss indicates leak severity—rapid drops (10+ PSI in 15 minutes) mean large leaks or multiple leaks, slow drops (5 PSI over 30 minutes) suggest small pinhole leaks. Pressure testing doesn't tell us where the leak is, but it confirms one exists and rules out meter malfunction or billing errors.

Video Pipe Inspection: We insert a waterproof camera on a flexible cable through cleanouts or cut-in access points to visually inspect your supply lines and drains. The camera transmits real-time video showing pipe interior condition—corrosion, mineral buildup, cracks, tree root intrusion, or collapsed sections. Video inspection is especially valuable for Sandy Springs homes with 50-60 year old copper pipes (common in Riverside and Mount Vernon Woods)—we can see pitting corrosion, thin pipe walls, and multiple weak spots that indicate system-wide failure rather than isolated leaks.

Best Use Cases: Pressure testing is our starting point when homeowners report high water bills but no visible leak and no obvious symptoms. It confirms leak existence before we spend time on pinpoint detection. Video inspection is essential when we suspect multiple leaks, need to assess repiping vs spot repair decisions, or when homeowners want to understand pipe condition before buying or selling a home. It's also critical for diagnosing drain problems—slow drains, backups, or sewer line issues that might be confused with supply line leaks.

Sandy Springs Pipe Condition Context: Homes built 1960s-1970s in Sandy Springs' Riverside and Mount Vernon Woods neighborhoods have 50-60 year old copper supply lines showing extensive pitting corrosion and thin spots. Video inspection often reveals that what homeowners think is a single slab leak is actually system-wide copper deterioration—10-15 pinhole leaks waiting to fail. In these cases, whole-house PEX repiping ($6,000-12,000) is more cost-effective than spot repairs ($1,500-3,500 each) that leave corroded pipe in place.

Homes with polybutylene pipes (installed late 1970s-1980s) have different failure patterns. Video inspection shows characteristic stress cracks at joints and fittings where polybutylene's chemical composition breaks down. These failures cluster around pipe connections, not randomly along pipe runs. Video inspection confirms polybutylene condition and supports repiping recommendations.

Process: Pressure testing takes 30-45 minutes—time to pressurize, monitor, and document pressure readings. Video inspection requires 1-3 hours depending on accessible cleanouts and pipe layout complexity. We document findings with written reports, pressure charts, and video recordings so you see exactly what we see. If pressure testing confirms a leak and video shows isolated corrosion, we proceed with electronic or acoustic pinpoint detection. If video reveals system-wide deterioration, we present repiping options.

Timeline: 2-4 hours for comprehensive pressure testing and video inspection. We often combine these diagnostic tools in a single visit, especially for homes over 25 years old where pipe condition is uncertain.

Cost in Sandy Springs: $250-600 for pressure testing, $300-800 for video pipe inspection. Combined diagnostic service (pressure test + video inspection) runs $500-1,200. These costs are often credited toward repair or repiping if you authorize work the same day. Insurance companies sometimes require pressure testing documentation before approving slab leak claims—we provide written reports that meet insurer requirements.

When We Recommend: We start with pressure testing when you suspect a leak but symptoms are vague (high water bill, meter activity with no obvious cause). Video inspection is essential for homes over 20 years old with original plumbing, homes with multiple past slab leak repairs, or when we find one leak and need to assess whether more are coming. If you're considering a home purchase in Sandy Springs' older neighborhoods, pre-purchase video inspection ($400-600) reveals pipe condition before you close and face expensive surprises.

Slab Leak Repair Options Compared

Once we've pinpointed your leak location and assessed pipe condition, we present repair options tailored to your home's construction, your budget, and your long-term plans. No single method is "best" for all situations—spot repair makes sense for isolated leaks in garages, while whole-house repiping is the right choice for homes with widespread copper corrosion. We explain each method's process, cost, timeline, and trade-offs so you make an informed decision.

Trenchless Epoxy Pipe Lining

Epoxy pipe lining creates a new pipe inside your existing copper or galvanized pipe without breaking concrete or opening walls. We clean the pipe interior with hydrojetting equipment (high-pressure water removes corrosion and mineral deposits), then coat the inside with two-part epoxy resin that cures to form a smooth, watertight barrier. The epoxy bonds to pipe walls, sealing pinhole leaks and preventing future corrosion. Once cured, the epoxy-lined pipe has restored flow capacity and a lifespan comparable to new PEX pipe.

Step-by-Step Process:

1. Access creation: We locate existing cleanouts or cut small access points (6x6 inches) in walls or floors to reach pipe ends. Cleanouts are preferred—they give us direct access without cutting.
2. Hydrojetting: We insert a high-pressure water jetting nozzle through the cleanout or access point and blast the pipe interior at 3,000-4,000 PSI. This removes corrosion scale, mineral buildup, and debris that would prevent epoxy adhesion. Spent water drains through the pipe system into your sewer or septic.
3. Drying: We blow compressed air through the pipe for 15-30 minutes to remove moisture. Epoxy won't bond to wet surfaces.
4. Epoxy application: We pull an epoxy-saturated liner through the pipe from one access point to the other, then inflate it with compressed air to press epoxy against pipe walls. Alternatively, we spray epoxy coating through the pipe using specialized equipment. The epoxy is food-grade, NSF-certified for potable water.
5. Curing: Epoxy cures at ambient temperature over 4-6 hours (faster in warm weather). We pressurize the line to ensure even coating and no air pockets.
6. Testing: After cure, we pressure test to 150 PSI for 15 minutes per Georgia plumbing code to confirm the repair is leak-free.
7. Access point restoration: We patch small access cuts with drywall, concrete, or matching flooring material. Cleanout-only access requires no restoration.

Best Use Cases: Epoxy lining works for single-line leaks in accessible pipe sections where you want to avoid concrete demolition and floor restoration. It's ideal for hot water mains or cold water supply lines under finished living spaces with tile, hardwood, or carpet you don't want disturbed. Epoxy is also effective for homes where exterior tunneling isn't feasible due to landscaping, driveways, or property line constraints.

Sandy Springs Application: Epoxy lining is popular in Sandy Springs neighborhoods with high-value flooring—tile homes in City Springs district, hardwood homes in Riverside, finished basement slabs in newer Perimeter Center construction. It preserves floor integrity while providing a permanent repair. However, epoxy requires accessible pipe ends. Homes built without cleanouts (common in 1960s-1970s construction) need 6x6 inch access cuts, which adds $300-600 for drywall or concrete patching.

Pros:

• No concrete breaking or floor removal in most cases
• 1-2 day completion from detection to restored water service
• Lifetime warranty on epoxy-lined section (material warranty 50+ years, we guarantee workmanship for life)
• Preserves high-value flooring like tile, hardwood, or specialty finishes
• Epoxy is NSF-certified for potable water, won't affect water quality
• Minimal disruption—you're out of water service for 6-8 hours while work is performed
• Cost-effective for single-line repairs compared to whole-house repiping

Cons:

• Requires accessible pipe ends (cleanouts or access cuts)—homes without cleanouts need wall or floor access openings
• Not suitable for severely corroded pipes with less than 40% remaining wall thickness—epoxy bonds to existing pipe, so structural integrity must remain
• Epoxy lines only the accessed section, not the entire plumbing system—leaks in other areas may occur later if copper corrosion is widespread
• Cannot line drain pipes—only pressurized supply lines
• Homes with polybutylene pipes are not candidates—polybutylene's chemical breakdown continues beneath epoxy lining

Process Walkthrough:

• Day 1 Morning: Detection and access point creation (if needed). Hydrojetting and drying takes 2-3 hours.
• Day 1 Afternoon: Epoxy application and pressurization. Cure begins, water service remains off.
• Day 2 Morning: Final pressure test, access point patching, water service restored. You're back to normal use.

For cleanout-based access with no cuts needed, the entire process completes in one day (6-8 hours).

Sandy Springs Considerations: Georgia's red clay soil and seasonal moisture cycles don't affect epoxy lining because the repair is inside the pipe—soil contact is irrelevant once epoxy creates the barrier. However, homes in Riverside and Mount Vernon Woods with 50-60 year old copper often have multiple thin spots. Epoxy lining one section solves that leak but doesn't address system-wide corrosion. We recommend video inspection before epoxy lining to assess whether other pipe sections are near failure.

Fulton County permits are not required for epoxy lining since no structural elements are altered and no concrete slab is penetrated. If we cut access openings in walls, those are considered minor repairs not requiring permits.

Timeline: 1-2 days from detection to water restoration. Single-day completion is possible when pipe ends are accessible through existing cleanouts. If we need to cut access openings, add half a day for patching and finishing.

Cost in Sandy Springs: $2,000-5,000 depending on pipe length, access difficulty, and number of access points needed. Typical hot water main lining (30-50 feet of pipe) runs $2,500-3,500. Cold water main lining (longer runs, 60-80 feet) costs $3,500-5,000. Access cuts add $300-600 for restoration. Homes with existing cleanouts save this cost.

Warranty: Lifetime workmanship warranty—if the epoxy-lined section leaks due to installation defect, we re-line it at no charge. Epoxy material has a 50-year manufacturer warranty against degradation. Warranty doesn't cover leaks in unlined pipe sections or new leaks from ongoing corrosion elsewhere in the system.

When We Recommend: Epoxy lining is our top choice when you have an isolated hot water or cold water supply line leak under finished living space, your pipe walls retain at least 40% thickness, and you want to preserve tile, hardwood, or carpet flooring. It's ideal for homeowners planning to stay in their Sandy Springs home 5-10+ years who want a permanent solution without the disruption of concrete demolition.

We don't recommend epoxy for homes with polybutylene pipes (epoxy won't prevent continued chemical breakdown) or homes with multiple leaks discovered during inspection (whole-house repiping is more cost-effective in those cases).

Copper to PEX Repiping

Copper to PEX repiping replaces your aging under-slab copper supply lines with new PEX (cross-linked polyethylene) pipes routed through your attic, crawlspace, or exterior wall chases—completely bypassing the concrete slab. We install a PEX manifold system near your water heater or main shutoff, then run individual PEX lines to each fixture (toilets, sinks, showers, washing machine). The old copper pipes remain under the slab but are depressurized and abandoned. This eliminates future under-slab leaks permanently.

Why PEX: PEX is flexible, freeze-resistant, corrosion-proof, and easy to route through tight spaces. Unlike copper, PEX doesn't develop pinhole leaks from water chemistry or electrolysis. It expands slightly when frozen (Georgia's occasional winter freezes), then returns to shape without bursting. PEX is NSF-certified for potable water, carries a 25-year manufacturer warranty, and costs 40-60% less to install than copper. Individual PEX lines from the manifold mean each fixture has its own shutoff—a toilet leak doesn't require turning off water to the entire house.

Full Repipe vs Reroute: A full repipe replaces all supply lines—hot water, cold water, and branch lines to every fixture. This is the comprehensive solution for homes with system-wide copper corrosion. A partial reroute replaces only the leaking section (hot water main, for example) and leaves other copper lines in service. Reroutes cost less upfront but don't address aging copper elsewhere in the system—you may face additional leaks in 2-5 years as other sections fail.

Best Use Cases: PEX repiping is the right choice when you have multiple slab leaks (current or past repairs), your copper pipes are 20+ years old with visible corrosion, or video inspection reveals widespread thin spots and pitting. It's also ideal for prevention-minded homeowners who want to eliminate under-slab leak risk permanently rather than patching individual failures as they occur. If you're planning to stay in your Sandy Springs home long-term, whole-house repiping pays off in peace of mind and avoided future repair costs.

Sandy Springs Application: PEX repiping is increasingly common in Sandy Springs' Riverside and Mount Vernon Woods neighborhoods where 1960s-1970s ranch homes have 50-60 year old copper supply lines. These homes typically have accessible attics with open joist bays—ideal for PEX routing. Attic temperatures in Georgia summers (120-140°F) require proper PEX insulation, which we include. Homes with finished attics or no attic access use crawlspace routing (if available) or exterior wall chases with weatherproof PEX rated for outdoor exposure.

City Springs district townhomes and condos built in the 2000s-2010s often have limited attic access and shared walls. In these cases, we route PEX through interior wall chases (behind drywall) or use exterior routing with cosmetic concealment. Coordination with HOA architectural committees is required for exterior routing—we handle this process.

Pros:

• Eliminates future under-slab leaks permanently—all supply lines are above-slab where they're accessible
• Improves water pressure and flow—new 3/4-inch or 1-inch PEX mains deliver better pressure than corroded copper
• Individual fixture shutoffs at manifold—isolate repairs without shutting off water to entire house
• PEX won't corrode, pit, or develop pinhole leaks—immune to Georgia's water chemistry and soil contact
• 25-year manufacturer warranty on PEX materials, lifetime warranty on our installation workmanship
• Freeze-resistant—PEX expands without bursting during rare Georgia hard freezes
• Faster installation than copper repiping—no soldering, fewer fittings, flexible routing
• Lower long-term maintenance costs—no future under-slab leak detection or repairs

Cons:

• Higher upfront cost than spot repairs—$6,000-15,000 for whole-house repipe vs $1,500-3,500 for single spot repair
• Visible piping in some areas—attic trusses, crawlspace joists, or exterior wall chases. We conceal where possible with soffit boxes or paint-matched wall chases
• Requires attic, crawlspace, or exterior access—homes with finished attics and no crawlspace need creative routing
• Multi-day project—2-5 days out of full water service depending on home size. We provide temporary water access for essential needs
• Attic routing requires insulation in Georgia heat—adds $200-400 to material costs but prevents PEX degradation from UV and temperature extremes

Process Detail:

1. Planning: We map your home's plumbing layout, identify optimal manifold location (near water heater or main shutoff), and determine routing paths (attic, crawlspace, or exterior). This takes 1-2 hours and includes measuring and material ordering.
2. Manifold installation (Day 1): We install the PEX manifold—a distribution panel with individual shutoff valves for each fixture. We connect the manifold to your main water supply, install pressure regulator (if needed), and verify manifold operation.
3. Main line routing (Day 1-2): We run 3/4-inch or 1-inch PEX mains through attic or crawlspace to central manifold. This requires drilling through top plates (attic access) or rim joists (crawlspace access). We insulate PEX mains per Georgia code.
4. Branch line connections (Days 2-4): We run individual 1/2-inch PEX lines from manifold to each fixture—toilets, sinks, showers, washing machine, outdoor hose bibs. Each line drops through walls or ceilings to reach fixture locations. We use PEX-specific fittings (crimp or expansion) at connection points.
5. Fixture reconnection (Days 3-5): We reconnect each fixture to new PEX supply lines, verifying hot and cold are correct and shutoffs function.
6. Pressure testing (Day 5): We pressurize the entire new PEX system to 150 PSI and hold for 15 minutes per Georgia plumbing code. This confirms leak-free installation before we close walls or restore ceilings.
7. Old system abandonment: We depressurize and cap the old copper supply lines at the water heater and main shutoff. Old pipes remain under the slab but carry no water.
8. Final inspection: Fulton County requires rough-in inspection (while PEX is visible in attic/walls) and final inspection (after system is pressurized and tested). We schedule both and obtain signed-off permits.
9. Insulation and concealment: We insulate all attic-routed PEX with foam pipe insulation, conceal visible runs with soffit boxes or painted wall chases where aesthetics matter.

Sandy Springs Code & Logistics: Georgia plumbing code requires PEX pressure testing to 150 PSI for 15 minutes—we document this for permit sign-off. Fulton County issues plumbing permits through the Sandy Springs Community Development Department; typical permit cost is $150-300 depending on project scope. Inspections are scheduled within 24-48 hours of request—we coordinate this so you're not waiting days between rough-in and final.

Attic access in Sandy Springs' ranch-style homes (Riverside, Mount Vernon Woods) is typically through hallway ceiling hatches or garage pull-down stairs. We protect attic insulation and HVAC ducts during routing. Crawlspace access (less common in Sandy Springs) is through foundation vents or dedicated crawlspace doors. Homes with neither attic nor crawlspace use exterior routing with UV-rated PEX and weatherproof mounting—this requires HOA approval in some neighborhoods.

Timeline:

• Reroute (single line): 1-2 days. We replace just the leaking hot water or cold water main, leaving other copper lines in service. You're out of hot water or cold water for 6-12 hours.
• Whole-house repipe: 3-5 days for typical 1,500-2,500 square foot Sandy Springs home. Larger homes (3,000+ sq ft) or homes with complex layouts take 5-7 days. You're out of full water service during work, but we provide temporary hose connections for essential bathroom and kitchen use.

Concrete cure time is not a factor with PEX repiping since we don't break any slab. Once final inspection passes, you have immediate full water service.

Cost in Sandy Springs:

• Reroute (single line): $4,000-8,000 depending on line length, routing complexity, and access difficulty. Hot water main reroutes (30-50 feet) run $4,000-6,000. Cold water main reroutes (longer runs) cost $6,000-8,000.
• Whole-house repipe: $6,000-12,000 for typical Sandy Springs home. Variables include:
  • Home size: 1,500 sq ft costs $6,000-8,000; 2,500 sq ft costs $8,000-10,000; 3,500+ sq ft costs $10,000-15,000
  • Number of fixtures: Each additional bathroom adds $800-1,200
  • Routing complexity: Open attic access is cheapest; finished attics or exterior routing adds $1,500-3,000
  • Manifold count: Homes with multiple stories or separate plumbing zones need multiple manifolds ($500 each)
  • Permit and inspection fees: $150-300 for Fulton County plumbing permit

Homes with polybutylene pipes (1970s-1980s construction) require whole-house repipe—partial reroutes don't address system-wide chemical breakdown.

Warranty: 25-year manufacturer warranty on PEX materials (Uponor AquaPEX, Rehau, or equivalent brands). Lifetime workmanship warranty on our installation—if fittings leak or connections fail due to installation error, we repair at no charge. Warranty covers all PEX lines, fittings, manifold, and pressure regulator. Does not cover fixture wear (faucet cartridges, toilet fill valves) or pre-existing copper pipes left under slab.

When We Recommend: We recommend PEX repiping when:

• You have multiple slab leaks (past or present)—indicates system-wide copper failure, not isolated problems
• Video inspection reveals extensive pitting corrosion, thin pipe walls, or 10+ pinhole leaks waiting to happen
• Your home is 20+ years old with original copper pipes—you're in the failure window
• You've had 2+ spot repairs in the last 5 years—repiping is more cost-effective than continued patching
• You're planning long-term ownership (10+ years in the home)—upfront investment pays off in eliminated future leak risks
• You have polybutylene pipes—chemical breakdown continues regardless of spot repairs; full repipe is the only permanent solution

We don't recommend repiping for isolated single leaks in newer homes (under 15 years old) with otherwise healthy copper. In those cases, spot repair or epoxy lining is more cost-effective. If you're selling your home within 2-3 years, spot repair gets you to closing without the investment of whole-house repiping.

Tunneling Under Foundation

Tunneling (also called hand-tunneling or foundation tunneling) is a repair method that preserves your interior flooring by accessing the leak from outside your home. We hand-dig a tunnel beneath your foundation slab from an exterior access point, reach the leaking pipe, repair or replace the damaged section, then backfill and restore landscaping. Your tile, hardwood, or carpet remains untouched.

Process: We identify the leak location (via electronic or acoustic detection), then mark the corresponding exterior location along your foundation perimeter. Using hand tools and small excavators, we dig a trench parallel to your foundation
