A slab leak — a leak in a water line running beneath a concrete floor — is one of the sneakier plumbing problems. You can't see it, but it quietly undermines the slab, spikes your water bill, and can damage flooring from below.
We locate slab leaks accurately and repair them the least-invasive way the situation allows, so you're not jackhammering an entire floor to fix one spot.
Signs of a slab leak
Slab leaks show up indirectly, so the clues matter:
- A warm spot on the floor (from a hot-water line leak)
- The sound of running water with everything off
- An unexplained jump in your water bill
- Cracks in flooring or the foundation
- Damp or buckling floor with no obvious source
What causes slab leaks
Pipes under a slab fail from age, corrosion, shifting soil, or abrasion where a line rubs against concrete. In this region, older homes with aging copper or galvanized lines are the most common candidates, and ground movement over the years doesn't help.
What to do before you call
If you suspect a slab leak, note the warm spot or damp area and check your meter for movement with all water off. Shutting the main can limit damage while you wait. Don't try to open the slab yourself — precise location first is what keeps the repair small.
How we repair a slab leak
We pinpoint the leak's exact location first, then choose the best repair for your situation — accessing and fixing the spot, or rerouting that section of line to avoid repeated slab work. We explain the trade-offs and give upfront pricing before doing anything.
As the EPA points out about the cost of ignoring household leaks a slow hidden leak wastes far more than most people expect.
When to call a pro
A slab leak is never a DIY repair — the location work and the repair both require the right tools and experience. The sooner you call after spotting the signs, the less damage the leak does to your slab and floors.
Frequently asked questions
How do you find a leak under concrete?
With specialized location equipment that pinpoints the spot, so we open the smallest possible area rather than guessing.
Do you have to break up my whole floor?
No. We locate the leak precisely first, and often can access just the spot or reroute the line to avoid repeated slab work.
What's the warm spot on my floor?
Often a hot-water slab leak warming the floor above it — a classic sign worth acting on quickly.
Why did the pipe under my slab fail?
Age, corrosion, soil movement, or abrasion against the concrete. Older homes with aging copper or galvanized lines are the usual candidates.
How urgent is a slab leak?
Urgent. It wastes water and can damage your foundation and floors, so early repair saves significant money.
Every slab repair starts with precise leak detection first so we fix the exact spot and nothing more.
