What's Included in Our Leak Detection Service
Every leak detection and repair visit covers the full job from isolation to pressure test. Here's what you get as standard, and where additional work might come up.
Work order
Leak Detection and Repair- Full System Isolation: We shut off the main, drain the lines, and confirm there's an active leak by watching the meter with everything off. This tells us whether we're chasing a supply leak, a drain leak, or a slab leak before we bring in detection equipment.
- Acoustic and Thermal Detection: We run acoustic listening equipment and a thermal imaging camera along the suspect run. Pressurized water makes a sound and a temperature signature. We follow both until they point to a single spot, usually within a square foot.
- Pipe Repair and Material Match: We repair the pipe with copper, PEX tubing, PVC, or CPVC to match what's already there. Joints are made with solder, SharkBite couplings, or PEX crimp rings depending on the material. We don't mix incompatible metals.
- Pressure Test and Documentation: Every repair is pressurized to 80 to 100 psi and held for 15 minutes. You get the reading in writing along with photos of the repair before it was closed up. That documentation is useful if you ever file an insurance claim.
- Access Point Restoration: We open the smallest access point possible and close it back up when the repair is done. Drywall patching and painting are not included, but we leave the opening clean and ready for your drywall contractor or handyman.

What Leak Detection and Repair charleston SC Really Involves
A leak that runs for another week costs more in water, damage, and mold than the repair itself. We find it, fix it, and test it before we leave.
Leak detection and repair charleston SC is the process of locating water escaping from a pressurized supply line, drain, or fixture and restoring that line to a code-correct, leak-free condition. We start by isolating the system, then use acoustic microphones, thermal imaging, and pressure gauges to narrow the leak to a square foot or less. Once we know exactly where it is, we open the smallest access point possible, repair the pipe with copper, PEX tubing, or a SharkBite fitting, and pressure-test the repair before closing up.
Charleston homes face leak conditions most inland cities never see. Salt air corrodes brass fittings and copper pipe faster here. Our soil shifts with the water table, stressing underground lines and slab plumbing. And the older housing stock across The Peninsula still runs original galvanized or thin-wall copper that's past its service life. That's why hidden leak detection charleston homeowners search for is rarely optional. If you've noticed a spike in your water bill or a warm spot on the floor, call us before the damage spreads.

How Our Leak Detection Process Works
No guesswork, no unnecessary demolition. Here's exactly what happens from the moment you call to the moment the line is dry and tested.
Tools and Methods We Use to Find Leaks
Each method answers a different question. Together they leave very little to guess.
Shows temperature differences on walls and floors. A hot water leak shows as a warm signature, and a cold supply leak shows as a cool one. We use it to confirm what the acoustic gear found.
Confirms the system holds pressure after a repair. We pressurize to 80 to 100 psi and hold for 15 minutes. If the gauge drops, the repair isn't done.
Lets us see inside drain and sewer lines. We use it to find cracks, root intrusion, and offset joints that could be leaking wastewater into the yard or under the slab.
Standard tools for opening and cutting the pipe at the repair point. We match the cutter to the material so the cut is clean and the new joint seats properly.
When to Call for Leak Detection and Repair
You got a letter from Charleston Water System saying your usage doubled compared to last year, but nothing in the house looks wet.
We isolate the system and watch the meter with everything off.
HomesYou noticed a warm spot on the tile floor in your West Ashley home and the tile above it has started to crack.
We confirm the slab leak with thermal imaging and mark the spot.
HomesA pipe burst in your crawlspace during a cold snap and water is spraying across the joists.
We shut off the main, drain the line, and repair the burst section with new copper or PEX.
HomesYou're selling your Peninsula home and the buyer's inspector flagged a slow drain and a stain under the kitchen sink.
We inspect the drain line with a sewer camera and check the supply connections under the sink.

How Leak Detection Runs in Charleston
Charleston's climate and housing stock shape every leak call we run. Salt air off the harbor corrodes brass fittings and copper pipe faster than inland cities see, which is why we find so many pinhole leaks in homes near the water.
Harleston Village
Many homes here date to the 1800s with original pipe chases and plaster walls. We use acoustic detection to avoid opening plaster whenever possible.
West Ashley
Slab-on-grade construction with copper under the slab. Soil movement and corrosion make slab leaks common here, and thermal imaging is our first tool.
Daniel Island
Newer builds with PEX systems. Leaks here usually show up at fittings or manifolds rather than in the pipe itself, so we check connections first.

PhotoPinhole Copper Leak in Harleston Village
Before: We isolated the system, confirmed an active leak with the meter, and ran acoustic detection along the kitchen wall. The leak was a pinhole in copper behind the cabinets, releasing about 15 gallons a day into the wall cavity.
After: We opened a 12-inch access hole, cut out the failed section, and sweated in a new copper joint. The line held 90 psi for 15 minutes. The wall cavity was dry within two days, and the next water bill was back to normal.
Slab Leak Under Tile in West Ashley
Before: A warm spot appeared on the kitchen tile and two tiles cracked within a week. Thermal imaging confirmed a hot water slab leak. The homeowner had been quoted a full floor tear-out by another company.
After: We marked the leak with thermal imaging and opened a two-foot section of slab. The copper line was repaired and rerouted overhead through the attic to avoid future slab work. The floor was patched the same day, and the warm spot was gone.
Burst Pipe in Mount Pleasant Crawlspace
Before: A cold snap burst a supply line in a Mount Pleasant crawlspace. Water was spraying across the joists and soaking the insulation. The homeowner shut off the main and called us at 11 p.m.
After: We arrived within the hour, drained the line, and cut out the burst section. A new PEX repair with crimp rings was installed and pressure-tested to 100 psi. The repair held, and the crawlspace was dried out over the next three days.
Leaks We Find and Fix Across Charleston
Most leak calls fall into a handful of categories. Knowing which one you're dealing with helps you decide how fast you need to act.
Water bill spiked with no visible leak
A hidden supply leak can waste 10 to 20 gallons a day.
Warm spot on the floor or cracked tile
A warm spot usually means a hot water line is leaking under the slab.
Water stain on ceiling or wall
A stain means water has been running for a while.
Water pooling in the yard
A wet spot in the yard usually means a buried supply line or sewer line is leaking.

What Charleston Customers Say
Charleston Harborline came out the next morning, ran their acoustic gear along the wall, and found a pinhole leak in the copper behind our kitchen cabinets. They cut one small access hole, repaired it, and pressure-tested it while we watched. Bill went back to normal the next cycle.
We had a warm spot on the tile floor and knew it was a slab leak. Two other companies wanted to break up the whole floor. These guys used a thermal camera, marked the spot, and opened a two-foot section. Repaired the line and rerouted part of it. Floor was patched the same day and we haven't had an issue since.
We manage six rental units and had a tenant reporting water stains on a ceiling. Charleston Harborline found the leak in a shower valve body within an hour, repaired it, and had the unit back in service the same day. They sent photos and the pressure-test reading for our records. That's the kind of documentation we need.
Leak Detection and Repair Questions Charleston Homeowners Ask
Short answers for the first few minutes. The team can cover the rest.
Still have a question?
Describe what you are seeing and we will point you to the right next step.
(854) 226-6111A visible fixture leak takes less time than a slab leak that needs acoustic and thermal scanning. The detection fee is separate from the repair. If we find and fix the leak the same visit, we quote the repair before we start, so you know the full number up front.
Shut off every fixture, then watch your water meter. If the dial still moves, you have a supply-side leak. Check the usual suspects first: toilet flappers, under-sink shutoffs, and the water heater pan. If those are dry, the leak is behind a wall or under the slab, and that's when you call us. We use acoustic listening gear and thermal cameras to pinpoint it without tearing up your home.
Yes. We run emergency leak repair charleston SC calls seven days a week, including nights and holidays. A burst pipe or an active slab leak can put hundreds of gallons into your home in an hour. Call us, shut off the main at the meter, and we'll get a technician out to stop the water and start the repair.
Slab leaks in Charleston usually come from three things: corroded copper pipe reacting to our soil and salt air, abrasive contact between pipe and concrete as the slab shifts, and high water pressure stressing joints over time. Homes built before 1990 with copper under the slab are the most common call. We locate the leak, then repair or reroute the line depending on how much pipe is affected.
