Signs a Leak May Be Under Your Slab

Slab leaks hide under the floor, so the clues show up elsewhere. These are the ones to watch for.

A Warm Patch on the Floor

A spot that feels warm underfoot, even when the heat is off, is worth a closer look. It can point to a leak under the slab. Tell us where you feel it.

Water Running With Every Tap Off

If you hear water moving when every fixture is closed, the sound may come from beneath the floor. Check that nothing is left running, then call us. We work to locate where it is coming from.

A Sudden Spike in Your Water Bill

A bill that jumps with no change in your habits can point to hidden water loss. Slab leaks are one possible cause. We help you narrow it down.

Leaks in walls or in the yard line have their own services, so tell us what you notice.

How We Locate and Repair a Slab Leak

A leak under the floor calls for a clear plan before any work begins. Here is how we approach it.

Listening to What You Have Noticed

We ask where the floor feels warm, when you hear water, and when the bill changed. Those clues help us narrow the search.

Walking You Through Your Options

Once we know the source, we explain what is happening and what choices you have. You decide with the full picture in front of you.

Locating the Leak Under the Floor

Our plumbers work to pinpoint where the water is escaping beneath the slab. Knowing the exact spot keeps the repair focused.

Completing the Repair You Choose

After you decide, we repair the leak. If the problem is bigger than one spot, we say so plainly. Replacement comes up only when repair would just delay the problem.

What You Gain From Acting Early

Acting on the first sign may help you:

Stop water from escaping under your floor
Protect flooring and the slab from ongoing moisture
Stop paying for water you never use
Learn exactly where the leak is
Choose a repair with your options explained
Avoid guessing about a hidden problem

Results depend on the location of the leak, how long it ran, and the condition of the lines.

Slab Leak Repair Service Questions Durham Homeowners Ask

What Affects the Cost of Slab Leak Repair?

The price depends on the leak’s location, the option you choose, and how easy it is to reach. You hear the number before work begins.

How Do I Know It Is a Slab Leak?

Common signs include a warm floor patch, water running with every tap off, and a sudden bill spike. A plumber has to locate the leak to confirm it. Call us if you notice any.

Does a Slab Leak Mean I Need a Repipe?

Not necessarily. Replacement comes up only when repair would just delay the problem. We explain what we find so you can decide.

What if the Water Will Not Stop?

Close the main water valve to stop the flow. Then call us at (919) 404-9040 during office hours, Monday to Friday, 8:30 am to 4:30 pm.
