Plumber in Charleston SC — From the French Quarter to Folly Beach and Every Neighborhood In Between
Fort Charle Plumbing provides water leak detection services throughout Charleston, South Carolina — from the centuries-old historic properties surrounding Rainbow Row, The Battery, and the Nathaniel Russell House to the growing residential communities of West Ashley, James Island, and Mount Pleasant, and the coastal properties along Folly Beach, Sullivan's Island, and the Isle of Palms. The hidden water leak problem is especially acute in Charleston's historic core neighborhoods — South of Broad, Harleston Village, Ansonborough, and the French Quarter — where original galvanized steel and early copper water supply lines installed 50 to 100 years ago are now well past their designed service life and frequently develop pinhole leaks, joint separations, and hairline cracks.
Charleston's position on a coastal tidal plain means the water table sits close to the surface year-round, and the same mobile Lowcountry sandy soil shifts constantly with rainfall, tidal fluctuation, and the ground saturation events that accompany the Atlantic hurricane season — creating continuous mechanical stress on buried water supply lines that would remain stable indefinitely in drier, more geologically stable environments.
We provide non-invasive leak detection that protects original architectural elements in Charleston's most significant neighborhoods.
Fort Charle Plumbing regularly responds to hidden water leak detection calls in the areas surrounding Charleston's most celebrated cultural sites.
We serve the residential communities surrounding Charleston's landmark destinations throughout Charleston County.

Hidden water leaks are the most financially damaging plumbing problem a Charleston homeowner can face — precisely because they are hidden. Unlike a burst pipe that demands immediate attention, a concealed leak inside a wall cavity, beneath a concrete slab, or underground along the yard-side water supply line can operate continuously for months before the accumulated water damage becomes visible. In Charleston's subtropical humidity environment, the structural and health consequences of a long-running hidden leak develop faster and with greater severity than in drier climates — making early professional detection a genuine financial and health-protective priority. If you notice any of the following warning signs, contact Fort Charle Plumbing immediately.
A water bill that rises steadily month over month without any change in household water use is the most consistent indicator of an active hidden leak — even a slow pinhole leak can waste 90+ gallons per day.
Turn off all water-using fixtures and check whether the water meter dial is still moving — any movement with all fixtures off confirms an active leak somewhere in the system.
Water staining, discoloration, bubbling paint, or peeling wallpaper on interior wall or ceiling surfaces indicates active moisture intrusion from a leaking pipe behind or above the affected surface.
Subfloor saturation from a leaking pipe beneath the floor creates soft spots, bounce, or visible warping in hardwood, laminate, or tile flooring — particularly in rooms adjacent to water supply lines.
A musty, earthy odor that cannot be traced to a visible source — particularly in rooms not normally moist — indicates active mold growth inside a wall or floor cavity driven by a hidden water leak.
Audible water sounds — dripping, hissing, or flowing — heard through walls, beneath floors, or from beneath the home when all fixtures are confirmed off indicates an active supply line leak.
A hot spot on a floor surface — detectable by walking barefoot or confirmed by thermal imaging — is the classic indicator of a hot water supply line leak beneath a concrete slab. Contact us for slab leak detection.
A sustained underground supply line leak near the foundation can erode supporting soil in Charleston's mobile Lowcountry soil, leading to differential foundation settlement and visible cracks in walls or door frames.
A section of lawn that is significantly greener or persistently wet without recent rainfall indicates an underground supply line or irrigation system leak feeding water into the surrounding soil. Pair with our water line repair service.
A gradual or sudden reduction in water pressure at multiple fixtures simultaneously — without a known supply interruption — can indicate a major supply line leak diverting pressurized water away from intended fixtures.
Noticing any of these warning signs? Don't wait — every hour of delay increases structural damage and water loss costs in Charleston's humid environment.
Call (843) 483-8585 — 24/7 Emergency DetectionWhy Charleston SC Homeowners Should Schedule Annual Leak Detection Inspection Every Year
The vast majority of Charleston homeowners who call Fort Charle Plumbing for emergency leak detection wish, in retrospect, that they had scheduled a routine annual plumbing inspection — because in almost every case, the evidence of the developing leak was present for months before visible damage triggered the investigation. An annual professional leak detection inspection is the only reliable way to catch slow, developing leaks in their earliest stage — before water bill escalation, structural damage, mold growth, and foundation issues transform a simple pipe repair into a complex, expensive property restoration project. Fort Charle Plumbing offers comprehensive annual leak detection and plumbing inspection services specifically designed for Charleston's demanding coastal environment.
| Inspection Task | Why It Matters for Charleston Homes |
|---|---|
| Water meter flow test | Confirms whether any measurable water flow is occurring with all fixtures off — the definitive first-step test for active hidden leaks in any Charleston property |
| Whole-home pressure testing | Measures system pressure and tests for pressure decay that indicates a leak in the supply system — identifies leaks too small to detect acoustically in their early stage |
| Acoustic listening scan (walls & floors) | Professional-grade electronic acoustic equipment amplifies water escape sounds through walls and floors — detects supply line leaks inside wall cavities before any visible damage appears |
| Thermal imaging scan (walls, floors, ceilings) | Infrared camera imaging identifies temperature differentials caused by water evaporation at leak points — maps moisture presence behind finished surfaces without opening a single wall |
| Moisture meter mapping | Digital moisture meters measure moisture content in wall, floor, and ceiling materials — identifies saturation levels that indicate active or historical leak activity |
| Underground supply line assessment | Pressure testing and acoustic scanning of the underground supply line from the meter to the home — the most common source of significant undetected water loss in Charleston's mobile soil environment |
| Slab area inspection | Thermal imaging and acoustic scanning of ground-level floor surfaces over concrete slabs — identifies the warm-spot signature of hot water slab leaks |
| Fixture and appliance connection inspection | Visual and pressure assessment of all supply connections at fixtures, appliances, and shut-off valves — identifies developing connection leaks before they fail completely |
| Irrigation system pressure test | Pressure testing of all irrigation zones to identify underground lateral line leaks — a significant source of undetected water waste in Charleston's landscaped residential properties |
| Drain line integrity check | Acoustic and visual assessment of accessible drain line connections for evidence of drain leak moisture penetration — complements our drain cleaning service |
| Written inspection report | Complete documentation of all findings, including any identified leak locations, moisture readings, pressure test results, and recommended repairs |
Charleston's near-surface water table applies constant hydrostatic pressure to underground supply lines, accelerating joint failure and making underground leaks develop faster than in drier markets — annual detection catches these before they become major losses.
Exterior metal pipe corrosion from Charleston's coastal salt air environment develops progressively — annual inspection identifies corrosion-driven pinhole leaks in exterior supply lines and hose bib connections before they penetrate fully.
Following tropical storms and hurricanes, Fort Charle Plumbing strongly recommends a full leak detection inspection — ground movement from storm saturation frequently opens previously hairline leak points into active leaks in underground supply lines.
A pinhole supply line leak wasting 90 gallons per day costs approximately $30–$50 per month in excess water charges — an annual inspection that finds and eliminates this leak pays for itself within the first billing cycle after detection.
Annual inspection reports provide written evidence of plumbing system condition — valuable for homeowner insurance claims, real estate transaction disclosures, and historic property maintenance documentation.
Professional annual leak detection and plumbing inspection in Charleston typically ranges from $200 to $500 depending on property size, system complexity, and the number of detection technologies applied — a fraction of the cost of the structural repairs, mold remediation, and water damage restoration that a single undetected long-running hidden leak creates in Charleston's humid environment.

Contact Our Team →How Charleston SC's Subtropical Coastal Climate Accelerates Pipe Failure & Hidden Leak Development
Charleston's geographic and hydrological position creates water leak conditions that are more severe, more rapidly damaging, and harder to detect than in most other American cities — a reality that makes professional water leak detection an essential property maintenance service rather than an optional investigation. The city sits on a low-lying coastal plain with a water table that hovers within a few feet of the surface throughout most of the historic core and coastal residential areas, maintaining constant hydrostatic pressure on buried supply lines and underground plumbing connections year-round. Charleston's subtropical climate drives the most aggressive mold growth conditions in the Southeast — meaning that a hidden leak inside a wall cavity in Charleston can generate a substantial, health-threatening mold colony in as little as 24 to 48 hours under summer temperature and humidity conditions.
Charleston's 75–80% average relative humidity ensures that any moisture introduced into a wall or floor cavity by a hidden leak is never able to evaporate before mold colonies establish — the standard 48-hour mold establishment window applies nearly every day of the year in Charleston's climate, making rapid leak detection a health imperative.
Atlantic storm events drive extreme rainfall, storm surge from Charleston Harbor, and ground saturation that shifts the mobile Lowcountry soil around buried supply lines — pipe joints that were barely maintaining integrity frequently open into active leaks following the ground movement events associated with tropical storm activity. Fort Charle Plumbing recommends post-storm leak inspection after any significant Atlantic storm event.
The near-surface water table throughout Charleston's coastal and historic core neighborhoods applies continuous upward hydrostatic pressure on underground supply lines and foundation drainage systems — accelerating joint fatigue and pipe wall stress in ways that underground pipes in higher-elevation markets do not experience. This affects properties near Isle of Palms and the coastal Sea Islands most severely.
Properties within miles of Charleston Harbor, Folly Beach, and the Sea Islands experience continuous atmospheric salt exposure that corrodes exterior metal supply components — hose bibs, exterior supply risers, above-grade irrigation connections, and exposed copper supply lines near exterior walls — at rates significantly faster than inland properties experience.
Historic Charleston neighborhoods contain some of the oldest residential plumbing infrastructure in the Southeast — galvanized steel supply lines that have been internally corroding and narrowing since installation, early copper supply lines with lead-based solder joints at risk of developing pinhole leaks, and original cast-iron supply fittings that have absorbed generations of thermal cycling. Our pipe repiping service addresses this root cause permanently.
Charleston's climate accelerates leak damage dramatically. Don't wait for visible damage — schedule a professional leak detection assessment today.
Call (843) 483-8585 — Same-Day Detection AvailableChoose the Right Water Leak Detection Technology for Your Charleston SC Property
For water leak detection in Charleston, Fort Charle Plumbing applies the full professional detection technology suite — matching the specific detection method to the suspected leak type, location, and the structural characteristics of your property. Not all leak detection situations call for the same technology, and applying the wrong approach wastes time, increases cost, and may produce inconclusive results that leave the leak unresolved. Our leak detection technicians assess your utility bill pattern, property age, visible symptoms, and structural configuration — then deploy the most effective combination of technologies to locate your leak with minimum disruption.
| Leak Type | Most Common Cause | Best Detection Method | Typical Charleston Occurrence |
|---|---|---|---|
| Behind-Wall Supply Line Leak | Pinhole corrosion in copper, joint failure in galvanized, fitting deterioration | Acoustic listening scan + thermal imaging | Extremely common in Charleston's historic neighborhoods with 40–80+ year old supply lines |
| Slab Leak | Copper pipe corrosion beneath concrete, thermal expansion cracking, soil movement under slab | Thermal imaging + acoustic amplification + pressure testing | Prevalent in post-WWII slab construction throughout West Ashley, James Island, and North Charleston |
| Underground Supply Line Leak | Soil movement, root intrusion, joint separation, corrosion | Acoustic ground microphone + pressure decay testing + ground assessment | High frequency in Charleston's historic neighborhoods and coastal properties where sandy soil shifts constantly |
| Irrigation System Leak | Lateral line joint failure, emitter damage, valve seal deterioration | Zone-by-zone pressure testing + acoustic ground scanning | Common throughout landscaped residential properties in Mount Pleasant, Summerville, and West Ashley |
| Pool & Spa Plumbing Leak | Return line joint failure, underground feed line pinhole, equipment pad connection deterioration | Pressure testing by zone + dye testing + acoustic scanning | Frequent in Charleston's high-pool-density coastal residential market — Folly Beach, Isle of Palms, Kiawah area |
| Foundation/Crawl Space Leak | Supply line joint failure in exposed crawl space, condensation-driven corrosion, thermal cycling cracking | Moisture mapping + visual inspection + acoustic confirmation | Common in Charleston's historic properties with original crawl space construction beneath ground floor rooms |
Professional electronic listening equipment amplifies the characteristic sound of water escaping under pressure through pipe walls, joints, or fittings — effective through walls, floors, and underground at depths up to several feet. This is the primary method for many hidden supply line leaks in Charleston homes.
Infrared cameras detect the temperature differential created at leak points by water evaporation. Hot water slab leaks create visible warm zones on floor surfaces; cold water leaks create moisture-cooled zones behind finished walls and ceilings.
The system is pressurized and monitored for pressure drop over a measured period — confirming whether a suspected leak is active and quantifying leak severity before more targeted detection begins.
Digital moisture meters measure moisture content in structural materials to map the extent of saturation around a suspected leak point and identify the direction of water travel through surrounding building materials.
Electromagnetic signal tracers locate the exact path of underground and concealed pipes before acoustic or thermal detection is applied — especially valuable in Charleston's older properties where original plumbing records often do not exist.
From First Call to Final Repair Verification — Transparent Leak Detection Service in Charleston SC
Every service begins with a structured assessment of your symptoms, utility bill history, property age, pipe material, and any visible evidence of moisture or damage. We immediately perform a water meter flow test with all fixtures confirmed off to determine whether an active leak is present before any technology is deployed.
We perform a complete supply system pressure test using calibrated digital manometers, isolating different sections of the plumbing to identify which area contains the active leak. This tells us whether the issue is on the street-side supply, interior supply network, irrigation system, or a specific isolated zone.
With the leak section isolated, we deploy the appropriate combination of acoustic listening equipment, thermal imaging cameras, moisture meters, and electronic pipe tracers to precisely locate the exact leak point. No wall, floor, or yard is opened until the leak location has been confirmed by instrument evidence.
After locating the leak, we provide a written leak detection report with photographic documentation, the technologies used, pipe condition observations, and a complete set of repair options with associated costs. You receive written estimates before any repair work begins.
For immediate repair authorization, our licensed technicians perform the repair using methods appropriate for the pipe material and location — including targeted pipe section replacement, water line repair, or repiping if the leak indicates broader deterioration.
After repair completion, we perform a full post-repair pressure test, final meter test, and moisture scan to verify the leak has been eliminated completely and to document remaining moisture levels for any needed restoration work.

Experience, Technology & Credentials That Leak Detection Competitors in Charleston SC Simply Can't Match
When you compare water leak detection contractors in Charleston, Fort Charle Plumbing stands apart on every dimension that determines whether you get an accurate leak location the first time or an expensive series of exploratory wall openings that cause more damage than the leak itself. We are a locally owned, deeply experienced Charleston plumbing company that has been finding hidden leaks across every neighborhood in the Lowcountry since 1990.
Real Results from Fort Charle Plumbing's Leak Detection Work Across Charleston SC Neighborhoods
The difference between an undetected hidden leak and a professionally located, documented, and repaired pipe is not just the elimination of the immediate water waste — it is the prevention of the cascade of structural damage, mold growth, and property value erosion that every week of continued hidden leakage produces in Charleston's demanding coastal environment.
A homeowner reported a water bill that had increased by $180 per month over four months with no change in water use. A general contractor suggested opening multiple wall sections in the kitchen and bathrooms to investigate.
Fort Charle Plumbing deployed acoustic detection and thermal imaging across the property — confirming within 90 minutes that the leak was a pinhole corrosion failure in a copper hot water line inside a first-floor interior wall, precisely located to within 6 inches. One small targeted wall opening provided full access for repair.
A family noticed warm spots on their living room tile floor and faint water sounds beneath the slab. Two HVAC companies and a general contractor had inspected and could not identify the source. The water bill had increased by $95 per month.
Thermal imaging identified a warm zone indicating a hot water slab leak. Acoustic amplification confirmed the leak origin at the center. A single precise slab access opening revealed a pinhole corrosion leak in a copper hot water line. Repaired, pressure-tested, and documented.
A commercial building owner received a monthly water bill of $4,200 — more than triple the property's normal consumption. No visible interior leaks were found.
Underground supply line pressure testing isolated the leak to the buried line between the water meter and main shutoff. Acoustic ground scanning located the leak point beneath the parking area before excavation. A single targeted excavation revealed a failed mechanical joint and enabled efficient repair.
Professional-Grade Detection Equipment & Code-Compliant Repair Methods for Charleston SC Properties
Every water leak detection service performed by Fort Charle Plumbing employs professional-grade detection equipment calibrated for accuracy in Charleston's specific environmental conditions — including acoustic interference from coastal ambient noise, the thermal complexity introduced by year-round high humidity, and underground detection challenges created by Charleston's high water table and mobile sandy soil.
Professional-grade electronic ground microphones and pipe contact listening equipment amplify the characteristic frequency of pressurized water escaping through pipe walls or joints — even through concrete slabs, finished walls, and soil depths up to several feet.
FLIR-grade thermal cameras capable of detecting temperature differentials as small as 0.1°C create a visual thermal map of scanned surfaces that identifies both hot and cold water leaks behind finished surfaces.
Calibrated digital manometers provide precise supply system pressure measurement and pressure decay testing to confirm leak presence and quantify leak severity before other technologies are applied.
Professional-grade digital pin and pinless moisture meters measure moisture content in wood, drywall, concrete, and other building materials — used to map existing saturation and identify water migration from the original leak source.
Electromagnetic pipe tracing equipment follows the path of metallic or tracer-wire-equipped plastic pipes underground and through walls — especially valuable in older Charleston properties with undocumented pipe routing.
High-definition waterproof push cameras inspect accessible interior pipe condition where internal corrosion, scaling, or deterioration may be contributing to the leak situation. This pairs naturally with our sewer camera inspection service where applicable.
Every repair performed after leak detection is completed to current South Carolina plumbing code, with permits pulled and inspections scheduled where required. Documentation is available for inspection and insurance records.
When to Start with Detection Only vs. Detection + Same-Visit Repair in Charleston SC
Understanding the relationship between professional leak detection and leak repair helps Charleston homeowners make the most informed decision when facing a suspected hidden leak. At Fort Charle Plumbing, we provide complete transparency about what detection accomplishes, what repair options follow, and how to choose the right path for your specific situation.
| Option | What It Is | Key Pros | Key Cons |
|---|---|---|---|
| Leak Detection Only | Non-invasive investigation using acoustic, thermal, and pressure technology to precisely locate a suspected hidden leak | Lowest initial cost; no demolition; documented leak location for informed repair or insurance claim | Leak remains active until repair is separately authorized and scheduled |
| Leak Detection + Same-Visit Targeted Repair | Detection followed by immediate repair at the confirmed leak point | Fastest resolution; single mobilization cost; leak eliminated within hours | Not appropriate for all leak types — complex slab or underground repairs may require separate scheduling |
| Leak Detection + Comprehensive Repair Scope | Detection followed by pipe section replacement, full repiping, or underground line replacement where broader deterioration is found | Addresses root cause; reduces recurrence risk; maximizes long-term reliability | Highest investment; may require permit, inspection, and multi-day execution |
| Annual Preventive Detection Survey | Routine annual inspection using the full detection suite before symptoms appear | Catches leaks early; prevents structural damage; least expensive intervention point | Annual inspection cost compared with savings from early detection |
From Basic Meter Testing to Full Property Leak Surveys — Charleston SC Price Ranges
Charleston homeowners facing a suspected hidden leak consistently want to understand what professional detection costs before calling — and the answer, in virtually every case, is that the cost of professional detection is a small fraction of the damage that continues to accumulate for every day the leak remains undetected and unrepaired. Fort Charle Plumbing uses a transparent estimating process that considers your property size, suspected leak type, detection technologies required, and repair scope.
| Service Type | Typical Charleston Price Range |
|---|---|
| Water meter flow test (initial leak confirmation) | Included with all detection services |
| Basic leak detection (acoustic + pressure, single area) | $150 – $350 |
| Advanced leak detection (acoustic + thermal + pressure, multi-area) | $300 – $600 |
| Full property leak detection survey | $400 – $800 |
| Underground supply line leak detection | $400 – $900 |
| Slab leak detection | $300 – $700 |
| Irrigation system leak detection | $200 – $500 |
| Emergency leak detection (after-hours dispatch) | $300 – $600 |

| Underground supply line repair (after detection) | $1,000 – $4,000+ |
| Commercial leak detection (multi-system) | $500 – $1,500+ |
Financial Context: The average Charleston homeowner with an undetected pinhole supply line leak loses $30–$80 per month in excess water charges — in addition to progressive structural damage. A professional leak detection service that locates and enables repair of an active leak often pays for itself within a few months of water bill savings alone.
Get My Leak Detection Estimate — (843) 483-8585Situations Where Only a Licensed Leak Detection Professional Can Find and Document Your Hidden Leak in Charleston SC
We recommend professional water leak detection using calibrated electronic equipment in any situation where a hidden leak is suspected and visual inspection alone cannot confirm the location. If your situation matches any of the following, our licensed team will assess your property, apply the right detection technology, and provide a written detection report with findings and repair options.
Unexplained utility bill increases are the most reliable early indicator of an active hidden leak and should trigger professional detection before structural damage compounds.
An active meter with zero water use is absolute confirmation that a leak exists somewhere in the system; the leak must be located before repair can be scoped.
Ceiling water stains indicate an active or historical leak above — professional detection locates the exact failure point before opening walls or floors.
Thermal floor anomalies are a classic indicator of a hot water slab leak and require thermal imaging and acoustic confirmation before any slab access is attempted.
Persistently wet yard areas indicate an underground supply line or irrigation system leak that requires acoustic ground scanning for precise excavation targeting.
Buyers and agents frequently request professional leak detection during due diligence when unexplained moisture, staining, or plumbing concerns are found in a property under contract.
Ground movement from storm saturation is a leading cause of newly active underground leaks in Charleston's mobile Lowcountry soil; post-storm leak detection is strongly recommended.
South Carolina homeowner insurance carriers require written documentation of leak location, detection methodology, and repair scope for hidden plumbing failure claims.

Water Leak Risks That Demand Immediate Professional Detection — Not Delayed Investigation in Charleston SC
Hidden water leaks generate a level of urgency that many Charleston homeowners underestimate — particularly when the only visible symptom is a water bill increase or a faint sound in the wall. In Charleston's subtropical humidity environment, delaying investigation is a financially dangerous decision. Mold can establish within 24–48 hours of water contact, structural wood can begin softening within days, and foundation soil erosion from a continuously leaking underground line can produce measurable movement within weeks.
A moving water meter dial with all fixtures confirmed off is proof of an active leak. Every hour of delay means measurable additional water loss and damage accumulation.
Water utilities rarely produce billing errors large enough to explain persistent month-over-month increases. A continued unexplained bill increase almost always indicates an active hidden leak.
Excavating or opening the wrong location can cause thousands of dollars in unnecessary damage and still leave the leak unrepaired. Professional detection confirms the point before any demolition begins.
Mold odor near a wall or floor indicates colony growth inside the assembly. The longer the moisture source continues, the larger and more expensive the remediation becomes.
The combination of foundation symptoms and potential underground water loss indicates a leak that may be actively eroding support soil. This requires emergency investigation, not routine scheduling.
Suspect a hidden leak right now? Call at the first sign of trouble — not after the ceiling falls or the mold spreads.
Schedule Immediate Leak Detection — (843) 483-8585Answers About Leak Detection Cost, Technology, Process & Emergency Service in Charleston SC
Professional water leak detection in Charleston typically ranges from $150 to $800 depending on the scope of investigation, the detection technologies required, and the property size. Basic acoustic detection for a single suspected area typically runs $150–$350, advanced multi-technology surveys using acoustic, thermal imaging, and pressure testing are often $300–$600, and full property surveys range from $400 to $800. Fort Charle Plumbing provides a written estimate before work begins.
The most reliable indicators are: a water bill that rises without any change in household use, a water meter dial that moves when all fixtures are off, unexplained wet spots or staining on walls, ceilings, or floors, warm spots on concrete slab floors, the sound of running water with all fixtures off, or a section of yard that stays wet without recent irrigation. If you notice any of these signs, schedule professional water leak detection immediately.
For most Charleston homes, the most accurate confirmation comes from combining acoustic amplification equipment with thermal imaging. Acoustic equipment hears pressurized water escaping, while thermal imaging visually maps the temperature differential created by the leak. When both technologies confirm the same point, the leak can be located with extremely high accuracy before any wall or floor is opened.
Yes. Fort Charle Plumbing provides genuine 24/7 emergency water leak detection throughout Charleston, including nights, weekends, and holidays. We dispatch from 10 fully equipped service vans and do not add an after-hours surcharge for emergency leak detection response.
Yes. This is one of the main reasons homeowners call us. Our thermal imaging locates the hot or cold anomaly through the floor surface and our acoustic equipment confirms the sound of water escaping at that same point. We then mark the exact area and make one targeted access opening rather than broad destructive demolition. If needed, we can pair that work with slab leak detection service and repair.
A targeted single-area survey usually takes 1–2 hours. A larger whole-property leak survey can take 3–5 hours depending on the property size, pipe routing, and the number of systems being tested. Thorough professional detection is almost always faster and less expensive than trial-and-error demolition.
Yes. Irrigation leaks are common in Charleston's landscaped residential properties. We perform zone-by-zone pressure testing and acoustic ground scanning to identify underground lateral line leaks, valve failures, and irrigation head connection problems.
Yes. Our written leak detection reports include confirmed leak location, photographic evidence, detection methodology, pressure test findings, and repair scope.

When you invest in professional leak detection — whether a targeted single-area investigation or a whole-property survey — you receive a written report documenting exactly what was found, where the leak is located, and the evidence supporting that determination.
If our detection identifies a leak location that subsequent repair work proves inaccurate, we conduct a follow-up detection service at no charge to identify the correct location.
