Quick answer
Slab leak cleanup handles water damage from a supply line failing beneath a concrete foundation — often discovered as warm floor spots, an unexplained water bill, or damp flooring. Typical cost is $2,000–$10,000 over about five days. The plumbing repair and the drying are separate jobs, and moisture trapped under flooring is what makes the restoration scope grow. In Los Angeles, CA, water damage jobs run $2,800–$18,000 for a residential home. Call (888) 840-6512 to reach a certified water damage restoration company serving Los Angeles, CA; the line is answered 24/7.

What Slab Leak Cleanup Involves
What causes it
- Copper pipe corrosion under the slab
- Foundation settling stressing supply lines
- Abrasion where pipes rub concrete or rebar
- High water pressure fatiguing joints
- Poor original installation without sleeves
How the work is done
- 1Do the meter test. Close every fixture and appliance valve, then watch the water meter. Movement over 15 minutes with everything off confirms a supply-side leak.
- 2Feel for warm floor spots. Walk barefoot over tile and concrete areas. A distinct warm patch usually marks a hot-water line leak directly below.
- 3Shut off the main if signs are active. If flooring is visibly wet or the meter spins fast, close the main shut-off until detection is scheduled. A pressurized leak flows continuously.
- 4Photograph everything with a timestamp. Wet baseboards, buckled boards, the water bill, the spinning meter — the record of when symptoms started supports the insurance claim.
- 5Book leak detection, not exploratory demolition. Electronic and thermal detection pinpoints the leak within inches. Breaking concrete on guesses multiplies both cost and repair time.
- 6Start drying as soon as the location is known. A certified crew can extract and begin drying flooring and walls while the plumbing repair is scheduled — waiting invites mold into wet materials.
Work follows IICRC S500. Typical duration 5 days; national cost range $2,000–$10,000.

How do I know if I have a slab leak?
Classic signs: a water bill that jumped without explanation, the sound of running water when everything is off, warm spots on the floor (hot-line leaks), damp carpet edges, cracking tile, or a water meter that spins with all fixtures closed. Two or more of these together justify a professional leak detection visit.
Does homeowners insurance cover slab leaks?
Most policies cover the water damage a slab leak causes — flooring, drywall, drying — and the cost of tearing out and repairing the slab to access the pipe.
The pipe repair itself is usually excluded, and gradual long-term leaks can be contested. Early documentation of when signs appeared strengthens the claim considerably.
What does slab leak repair cost?
Detection runs $150–$500. The plumbing fix ranges from $500 spot repairs to $3,000–$6,000 for rerouting the line overhead. Water damage cleanup and drying adds $1,500–$5,000 depending on how much flooring and drywall the leak reached before discovery. Whole projects typically land between $2,000 and $10,000.
Repair, reroute, or repipe — which is right?
A single accessible leak in otherwise healthy pipe favors a spot repair. A leak in aging copper that has already failed elsewhere favors rerouting that line through walls or attic.
Multiple leaks across the system point to repiping. Get the water damage dried regardless — wet materials do not wait for plumbing decisions.
Can a slab leak damage the foundation itself?
Left running, yes. Constant water under a slab can erode supporting soil and cause differential settling, cracking, and door misalignment. That secondary damage costs far more than the leak repair. Treat persistent under-slab moisture as time-critical even when the visible symptoms seem minor.
Who do I call right now for water damage?
Call (888) 840-6512. The line is answered 24 hours a day, seven days a week, and connects you with an IICRC-certified water damage restoration company that serves your area. A recorded menu picks up first: choose water damage or mold, key in your 5-digit ZIP code, and hold through the short silence while the call is passed to the company.
Describe what you can see — where the water is coming from, how long it has been there, and whether it smells — the more specific you are, the faster the right company is on the line. If the source is a pipe or an appliance, shut the main water valve first. Have four things ready and the call goes quickly: the address, when the water started, what is wet now, and whether you have filed an insurance claim.
