Slab Leak Repair
Foundation and under-slab leak detection and repair. We find it and fix it with minimal disruption.
Under Your Foundation. Leaking.
There's a warm spot on your floor. Or maybe your water bill doubled last month and you can't figure out why. You've checked every faucet, every toilet, every visible pipe. Nothing is leaking. But something is. The leak is under your slab. Hot or cold water lines running beneath your concrete foundation have developed a pinhole or a crack, and water is slowly seeping into the ground. You can't see it. You can't reach it. And every day it runs, it's eroding the soil under your foundation and driving up your bill. Slab leak repair is one of the most specialized plumbing jobs there is. Cole's Plumbing has been locating and repairing slab leaks in DFW homes since 2001. We use electronic leak detection to find the exact spot, then give you repair options that range from a spot fix to a full reroute overhead. We don't start digging until we know exactly where the problem is.

How It Works
Slab leaks are tricky. Precision matters more here than almost any other plumbing job.
Electronic leak detection
We use acoustic listening equipment and thermal imaging to pinpoint the leak location through the slab. No guessing, no exploratory jackhammering. We find it within inches. Our service call covers the initial visit.
Repair options explained
You typically get three choices. Spot repair: we open the slab at the leak, fix the pipe, and patch. Reroute: we abandon the under-slab line and run a new one through the attic or walls. Repipe: if multiple lines are failing, we replace everything. Each option has different costs and long-term implications.
Execute the repair
Spot repairs take 4 to 6 hours including concrete cutting and patching. Reroutes take a full day. Either way, you have running water by the end of the visit.
Concrete and cleanup
For spot repairs, we patch the concrete opening and clean up all debris. The patch cures in 24 hours. You can walk on it the same day with care.
Why Cole's
Pinpoint Accuracy
Our electronic detection equipment locates leaks within 6 inches through concrete. We don't open your slab until we're sure. That precision saves you money and concrete damage.
All Three Options Available
Some plumbers only do spot repairs. Some only do reroutes. We do all three, so our recommendation is based on what's best for your home, not what's the only thing we know how to do.
Foundation Awareness
Slab leaks and foundation damage go hand in hand. We work with foundation repair companies regularly and can coordinate if both are needed. We understand the relationship between the two.
$2M Liability Coverage
Cutting into a slab is serious work. Our $2M insurance policy protects your home if anything unexpected happens during the repair.
200+ Five-Star Reviews.
Chad came out the same day we called. He looked at our water heater, told us exactly what was wrong, gave us a price, and got it done that afternoon. No surprises on the bill. We've used other plumbers in the area and this was by far the best experience.
The last plumber we called tried to sell us a whole new system when all we needed was a valve replacement. Chad was honest about what the actual problem was and fixed it for a fraction of what the other company quoted. That's rare.
We had a slab leak and were panicking. Chad walked us through the whole process, explained what he was doing at every step, and his price was fair. He even followed up the next week to make sure everything was holding. This is the only plumber we'll call from now on.
Straight Answers.
Two methods. Acoustic detection uses sensitive microphones to listen for the sound of water escaping under pressure through concrete. Thermal imaging detects temperature differences on the slab surface caused by hot water leaks. Together, they pinpoint the location within 6 inches.
If you have copper pipes with one leak and the rest of the piping is in good shape, a spot repair makes sense. If you have copper pipes and this is your second slab leak, reroute. The copper is failing systemically and more leaks are coming. If you have polybutylene (gray plastic pipe), always reroute or repipe.
We quote after detection, once we know exactly where the leak is and what's involved. Options range from a spot repair through the slab to an overhead reroute to a full repipe. Each has different tradeoffs and we lay them all out clearly before any work starts.
Yes, over time. Water erodes the soil under the slab, causing it to shift and crack. The longer the leak runs, the worse the foundation damage gets. If you suspect a slab leak, don't wait — a plumbing repair now prevents a far more expensive foundation repair later.
Most homeowner policies cover the water damage caused by a slab leak but not the plumbing repair itself. Some policies cover detection costs. Check your policy and call your agent. We provide documentation for insurance claims and work with adjusters regularly.
