Accurate Slab Leak Detection for Houston Homes
Most Houston-area homes are built on concrete slab foundations, with water lines running underneath. When one of those lines leaks, the water has nowhere to go but into the soil and up into your flooring. Slab leaks are easy to miss and expensive to ignore.
Heaton Plumbing confirms the leak, pinpoints its exact location under the slab, and repairs it using the least disruptive option that makes sense for your home. It is one part of our complete leak detection services, and we handle every step from detection to repair.

Slab Leak Warning Signs
Warm or Hot Spots on the Floor
A leaking hot water line under the slab can make tile, wood, or carpet feel warm in one area.
Unexplained High Water Bill
Water escaping under the foundation runs around the clock, which shows up on your bill.
Running Water Sounds
Hearing water moving when every fixture is off is a classic slab leak symptom.
Damp Flooring or Musty Odors
Moisture wicking up through the slab can damage flooring, baseboards, and drywall, and lead to mold.
New Cracks in Floors or Walls
Water under the foundation can affect the soil beneath your home over time.
Water Heater Running Constantly
If hot water is leaking under the slab, your water heater keeps working to replace it.
Slab Leak Repair Options
Once we find the leak, we explain each option and recommend the one that fits your home and your pipes.
| Repair Option | How It Works | Best For |
|---|---|---|
| Spot repair | We open the slab only at the leak location and repair the damaged section of pipe. | A single leak in pipe that is otherwise in good condition |
| Line reroute | We abandon the leaking line and run a new line through walls or the attic instead of under the slab. | Aging pipe, repeat leaks, or leaks under finished flooring |
| Whole-home repiping | We replace the home’s water supply piping with new lines. | Homes with multiple leaks or failing original plumbing |
What to Do If You Think You Have a Slab Leak
- Turn off every fixture and check whether your water meter is still moving
- If water is surfacing through the floor, shut off the main water valve
- If the floor feels warm, turn off the water heater until the leak is found
- Move rugs and furniture away from wet or warm areas
- Photograph damage for your records and insurance
- Avoid breaking up flooring to search for the leak yourself
Slab Leaks and Mold
- Musty odors near baseboards
- Discolored or lifting flooring
- Peeling paint low on walls
These signs often mean water has been leaking for a while. The sooner the leak is stopped, the less damage and mold you will have to deal with.

Slab Leak FAQs
What are the warning signs of a slab leak?
Common signs include warm or hot spots on the floor, a water bill that rises for no reason, the sound of running water when everything is off, damp or warped flooring, musty odors, new cracks in floors or walls, and a water meter that keeps moving when no water is in use. A water heater that seems to run constantly can point to a leak in a hot water line.
Can a slab leak cause mold?
Yes. Water from a slab leak can soak into flooring, baseboards, and the bottom of walls, creating the damp conditions mold needs. Musty odors are often one of the first clues. Finding and stopping the leak quickly is the best way to limit mold growth.
How do you find a slab leak without breaking up the floor?
We confirm the leak with meter and pressure testing, then use acoustic listening equipment and thermal imaging to pinpoint where water is escaping under the slab. That lets us limit any floor access to the spot that actually needs repair. Learn more about our leak detection methods.
Should I repair the slab leak or reroute the line?
A direct spot repair often makes sense for a single leak in otherwise healthy pipe. If the pipe is aging, has leaked before, or sits under finished flooring that would be costly to open, rerouting the line through the walls or attic is often the better long-term choice. We walk you through both options before any work begins.
Does homeowners insurance cover slab leak repair?
It depends on your policy. Many policies help with the cost of accessing the leak and repairing resulting water damage, but may not cover the pipe repair itself. Check with your insurance provider, and keep the documentation we provide about where the leak was and what we found.
Is a slab leak an emergency?
If water is surfacing through the floor or spreading quickly, shut off your main water valve and call us right away for emergency plumbing service. Even a slow slab leak should be addressed promptly, since ongoing leaks can damage flooring, encourage mold, and affect the soil under your foundation.
