7 Warning Signs of a Slab Leak
A slab leak is a broken water line under your foundation. Catching it early in a Coachella Valley home saves thousands in flooring, drywall, and mold remediation. Here are the seven signs desert homeowners should never ignore.
Warm or hot spots on the floor
A hot-water slab leak radiates heat through the concrete. If one area of tile or flooring feels noticeably warmer, it's the #1 tell in Coachella Valley homes.
The sound of running water when nothing is on
Shut every fixture off and listen near walls and floors. A steady hiss or trickle under the slab almost always means a pressurized line has failed.
A sudden spike in your water bill
A pinhole slab leak can waste 50–200 gallons per day. If your bill jumps with no change in usage, get a pressure test before it gets worse.
Low water pressure throughout the house
Slab leaks bleed off system pressure. If every fixture is weak — not just one — the leak is likely upstream of the manifold.
Cracks in flooring, drywall, or the foundation
Long-term slab leaks saturate the soil under the foundation, causing settling and hairline cracks in tile grout, drywall corners, and stucco.
Mildew smell or damp carpet
Musty odors, warped baseboards, or damp spots on carpet — especially against exterior walls — often trace back to a slow slab leak.
Your water meter keeps ticking
Turn off the main valve at the house and watch the meter. If it still spins, the leak is between the meter and your home — often under the slab.
What to do if you spot the signs
Don't wait — slab leaks get more expensive every week they run. A licensed plumber uses electronic acoustic detection to pinpoint the leak within inches before any concrete is cut. Want the full price breakdown? Read our slab leak repair cost guide.
