Slab Leak Detection & Repair in Keller, TX

Here’s how to narrow it down, and how to get matched with a licensed local plumber when it really is a slab leak. Fort Worth Leak Detection is a referral and matching service, not a plumbing company.

Rule out the outdoor suspects first

Before assuming the worst, check the things that commonly cause high bills on larger Keller properties:

• Irrigation. Broken heads, cracked lines, or a stuck valve can waste a lot of water. Turn off the irrigation system’s backflow valve and see if the meter stops.
• Pools. An auto-fill that runs constantly can mean a pool leak rather than a house leak. Pool leak detection is a specialty of its own.
• Hose bibs and outdoor kitchens. Drips add up over a month.
• Toilets. A silently running toilet is still the most common culprit indoors.

Then run the meter test on our slab leak detection page with everything off, including irrigation and pool fill. If the meter still moves, close the home’s main shut-off. If it stops, the leak is inside the house.

Why trees and big lots matter

Large trees near a foundation pull moisture from the clay, while sprinklers keep other areas wet. That uneven moisture makes the soil, and the slab, move unevenly, which stresses the pipes underneath. Bigger lots also tend to mean longer service lines from the meter to the house, which is more buried pipe that can leak. See water line and sewer leaks.

Signs inside the house

• A warm spot on the floor, often noticed on tile
• The sound of running water with all fixtures off
• Damp or musty carpet, or swollen wood flooring
• Lower water pressure or a water heater that runs constantly

Repair options for Keller homes

Many Keller homes have finished floors that owners would rather not break up, like large-format tile, wood, or stone. That often makes tunneling or an attic reroute worth considering instead of a spot repair through the floor. Newer homes may also have post-tension slabs, which call for extra care before any concrete is cut. Ask the plumber how they’ll handle it.

If water has already reached flooring or walls, see water damage after a leak. For foundation symptoms after a leak, our sister site Fort Worth Foundation Fix covers Keller foundation inspections.

Before you hire anyone in Keller

• Look up the plumber’s license on the TSBPE public license search.
• Ask how they’ll locate the leak and how precise they expect to be before cutting concrete.
• Get the repair scope in writing, including who handles concrete, flooring, drywall, and permits.
• Ask about written warranties on the repair. Terms vary by company.
• Call your insurance company early if there’s water damage. See our insurance FAQ.

Costs and insurance in Keller

Leak detection is usually a paid service, and national cost guides put it at roughly $150–$400, with typical slab leak repairs around $630–$4,400 including detection (Angi, 2026). Those are national figures, and Keller quotes depend on access, repair method, flooring, and any water damage. Many homeowners policies help with sudden water damage and the cost of reaching the pipe, but not the pipe itself. Check your policy, and see our FAQ on signs, costs, and insurance.
