Most homes in Frisco, McKinney, Plano, and nearby cities are built on concrete slab foundations. Much of the area sits on expansive clay soil that swells when wet and shrinks when dry, which can stress the slab and the plumbing in or under it.
Warning signs
- Warm spots on the floor (a possible hot water line leak)
- An unexplained jump in your water bill
- The sound of running water when everything is off
- Damp carpet, cupping wood floors, or cracked tile
- Musty odors near the floor
A quick meter test
Turn off every faucet and water-using appliance, then watch the water meter. If it keeps moving, water is going somewhere.
Who to call
A licensed plumber uses leak detection to find and repair the pipe. A restoration company dries the slab, flooring, and walls and documents the damage. Some homeowners also involve a foundation professional if there are signs of movement.
Insurance
Policies differ on slab leaks. Many cover tear-out to access the pipe and the resulting water damage, but the pipe repair itself may be handled differently. Ask your insurer before work starts.
