Slab leaks are repaired one of three ways: open the floor at the leak and splice it, reroute that line through the walls or attic, or repipe the house when the lines are failing in more than one place. We recommend the one that fits the age and condition of your pipes.
Signs you need slab leak repair
- A warm or damp area on a tile or wood floor
- Running water sound with every fixture off
- Cracks in tile or flooring that keep spreading
- Low hot water pressure and a water heater that cycles more
- Mildew under carpet near an interior wall
How we handle it
- Confirm it is under the slabPressure tests on the hot and cold sides tell us which line is losing water and that it is below the floor.
- Locate the breakElectronic listening and line tracing put the leak within inches, so any opening in the floor stays small.
- Choose the repairSpot repair for a single failure on otherwise good pipe; a reroute when the line is old or hard to reach; a repipe when failures keep coming back.
- Test and close upThe repaired line is pressure tested before the floor or wall is patched.

What you can do before we arrive
If you suspect a slab leak, close the valve to the water heater cold inlet and check the meter again. If it stops, the leak is on the hot side, which is the most common case. Write down what you found; it saves time on the visit.
What we see in Upstate homes
Slab homes are common in the newer neighborhoods ringing Greenville, from Five Forks to the subdivisions off Woodruff Road and around Greer. Many were plumbed with copper under the slab, and the Upstate clay soil moves enough over the years to stress those lines where they rub against rebar or gravel. A reroute through the attic is often the cleaner long-term answer in these one-story houses.
Keeping it from coming back
Slab leaks are hard to prevent outright, but keeping house pressure under 80 psi reduces stress on buried lines, and a pressure reducing valve and expansion tank in good working order help copper last longer.
Questions about slab leak repair
Will homeowners insurance pay for a slab leak?
Policies vary. Many cover the cost of getting to the leak and repairing the damage it caused, but not the pipe itself. We document what we find so you can file a clear claim.
Is a reroute better than breaking the slab?
Often, yes. A reroute avoids jackhammering inside the house and replaces the old run with new pipe. A spot repair can make sense for a single failure on otherwise sound pipe.
How long does a slab leak repair take?
Most spot repairs and single-line reroutes are finished in one day. A full repipe usually takes two to four days.
