Why Lewisville homes need these repairs

Lewisville sits on the shore of Lewisville Lake north of Dallas, with mostly 1970s–90s slab homes and many apartments. The city treats lake water at its own plant and buys more from Dallas, and North Texas clay soil, summer heat and hard freezes drive slab leaks and frozen pipe calls.

Lewisville plumbing questions

How do I know if my Lewisville home has a slab leak?

Warm spots on the floor, the sound of running water with everything off and a meter that keeps moving are the usual signs; a plumber can pinpoint it before opening the floor. Why it comes up in Lewisville: Expansive clay moves slab foundations of 1970s–90s homes.

Who can thaw a frozen pipe in Lewisville?

A plumber can thaw the line safely, check it for cracks and repair any split section before water damage spreads. Why it comes up in Lewisville: Hard freezes catch attic and exterior-wall pipes.

Is Lewisville's water from Lewisville Lake?

Yes. The city treats lake water at its own plant and buys additional treated water from Dallas.

Why do slab leaks happen in Lewisville homes?

North Texas clay swells and shrinks with rain and drought, moving the slab and stressing pipes underneath.

Do Castle Hills homes have different water service?

Castle Hills was developed with its own utility districts, so service and billing can differ from the rest of Lewisville. Check your bill.

How do I prepare Lewisville pipes for a freeze?

Insulate attic and exterior-wall pipes, cover hose bibs, and drip faucets on the coldest nights.
