Suspect a slab leak? Limit damage.
Leaks under a concrete slab can warm floors, spike water bills, and soak finishes from below. Shut water if needed, then check your ZIP.
Do this now
- If the leak is active, shut the main water supply.
- Note hot spots on floors, unexplained moisture, or sudden bill spikes.
- Photograph affected rooms and any foundation-adjacent dampness.
- Avoid cutting concrete yourself.
- Check your ZIP on DryCalm for guidance and a restoration line when coverage exists.
When to get help
Call for professional mitigation if you have standing water, wet drywall or carpet, sewage, a sagging ceiling, or any electrical risk. DryCalm is not 911 and does not give free quotes — when partner coverage exists for your ZIP, we show a number to call. Contractors are independent; DryCalm may be compensated for connections.
FAQs
Is a slab leak always a plumbing emergency?
Active water under the slab usually is — ongoing moisture damages finishes and can feed mold. A plumber locates the line; restoration handles drying.
Can DryCalm find the leak?
No. We help with next steps and may connect you to restoration when your ZIP is covered. Leak location needs plumbing diagnostics.
Warm floor spots — is that a slab leak?
It can be — especially with unexplained high water bills. Shut the main if water is active, then get plumbing diagnostics and drying help.
Does DryCalm give free quotes for burst pipe?
No. DryCalm is free guidance — not a quote marketplace. When partner coverage exists for your ZIP, we show a number to call an independent contractor. DryCalm may be compensated for connections.
Should I call before or after contacting insurance?
If unsafe, call 911 first. Otherwise stop the water if safe, photograph damage, then call your insurer and get a mitigation assessment. Order can vary by policy — document timing either way.
