Your water bill jumped for no reason. One spot on the floor feels warm underfoot. You hear water running when every faucet is off. Something’s leaking — but you can’t see where.
Here’s what may be happening. A slab leak is a leak in the water pipes running beneath your home’s concrete foundation. Because it’s hidden under the slab, it can damage floors, walls, and the foundation itself before you ever see water. All Clean Restoration finds and dries slab leak damage across the Metro East and St. Louis.
What Are the Warning Signs of a Slab Leak?
A slab leak hides, but it leaves clues. Watch for these:
- A spike in your water bill with no change in usage.
- Warm or damp spots on the floor, especially with a hot-water line leak.
- The sound of running water when nothing is turned on.
- Cracks in flooring or walls as moisture shifts the slab.
- A musty smell or mold near the floor.
- Low water pressure across the house.
Any one of these is worth checking. Two or more, and you likely have a hidden leak.
Why Are Slab Leaks So Damaging?
Because they run for weeks or months before you notice. All that time, water is soaking into materials you can’t see.
Left alone, a slab leak can:
- Feed mold under flooring and inside walls.
- Warp and ruin hardwood, laminate, and subfloor.
- Undermine the foundation as soil shifts and settles.
- Raise humidity throughout the home.
A slow, hidden leak like this is exactly how water quietly damages a foundation before anyone realizes.
What Should You Do If You Suspect One?
Act quickly, even though you can’t see the water. A few steps help right away:
- Shut off the water at the main if you can identify heavy leaking.
- Note the signs — the warm spot, the bill, the sound — to help pinpoint the source.
- Call a professional to locate the leak without tearing up the whole floor.
- Start drying the affected area before mold takes hold.
The plumber fixes the pipe. The restoration crew handles the water damage the leak already caused.
How Do Professionals Find and Dry a Slab Leak?
We use technology to find the water, not a jackhammer. Moisture meters and thermal imaging map where the water has spread.
That lets us target the drying instead of tearing out your whole floor. We dry the slab, subfloor, and walls with our Pro Drying Services, then verify the moisture is gone. If flooring or drywall is beyond saving, we handle the full water damage repair.
Does Insurance Cover Slab Leak Damage?
Often the resulting damage is covered, even when the pipe repair isn’t. Policies frequently pay to fix the water damage from a sudden leak.
We document the cause and the damage for your adjuster. See how that works on our insurance FAQ.
