Signs of a Slab Leak

Many Orange County homes are built on concrete slabs, so the pipes are out of sight. Watch for these:

  • A water bill that jumps with no change in how you use water
  • The sound of running water when everything is turned off
  • Warm or hot spots on the floor, which can mean a leaking hot water line
  • Damp, discolored or lifting flooring, or a musty smell
  • Low water pressure throughout the house
  • Cracks or wet spots along the foundation or outside walls

A quick check: Turn off every faucet and appliance that uses water, then look at your water meter. If the dial or leak indicator is still moving, water is going somewhere. Call us.

How We Find the Leak

We confirm where the leak is before we open anything, so the repair is as small as it can be. Then we explain what we found and give you your options and a price.

Repair or Reroute: Which Makes Sense?

There are two good ways to fix a slab leak. We'll recommend the one that fits your house, even when it's not the bigger job.

Spot repairReroute above ground
What we doOpen the slab at the leak and repair or replace that section of lineAbandon the underground line and run a new one through walls, attic or above ground
Best whenOne leak, and the rest of the pipe is in good shapeOld pipe, repeat leaks or hard-to-reach lines
Slab damageSome slab openingLittle or none
Long termOther underground sections can still leak laterRemoves the underground line from the equation
CostUsually lower up frontUsually higher up front

If your whole house has old pipe, repiping can solve the leak and everything behind it at once.

Slab Leaks We've Fixed

A Reroute in Anaheim

A homeowner in Anaheim had a slab leak. We pulled the old water lines out of the ground and ran them above ground, so they can't leak underground again.

A Leak Under a Parking Lot

We repaired a leak on a 1½" water line under a parking lot.

Slab Leaks and Insurance

Ask your insurance company whether your policy covers slab leaks and the damage they cause. Photos of the damage, your water bills and a written description of the repair can help.

Slab Leaks in Commercial Buildings and Parking Lots

Property managers and business owners have slab leaks too, often under parking lots, walkways or ground-floor units. We schedule work around your tenants and operating hours, and we send photo documentation and a clear invoice when we're done.

Slab Leak FAQs

How do I know if I have a slab leak?
Common signs are a rising water bill, the sound of running water, warm spots on the floor and damp flooring. If the water meter moves with everything off, water is leaking somewhere.
Can a slab leak fix itself?
No. A leaking line keeps leaking. Turn off the main valve if you can and call us.
Do you have to break the concrete?
Sometimes. A spot repair opens the slab at the leak. A reroute runs new lines above ground and usually avoids opening the slab. We'll explain which fits.
Is rerouting better than repairing?
It depends. A reroute makes sense for old pipe or repeat leaks. A spot repair can be enough for one leak in healthy pipe. We'll give you honest advice on both.
How much does slab leak repair cost?
It depends on where the leak is and which repair you choose. We give you an upfront price before work starts.
Do you handle slab leaks at night and on weekends?
Yes. We're open 24 hours a day, 7 days a week.
