Why Denton homes need these repairs
Denton is a North Texas university city with older houses near the square and campuses, a large renter population, and fast-growing subdivisions on the edges. The city treats water from Lake Lewisville and Lake Ray Roberts, and expansive clay soil, hard freezes and summer drought are behind most foundation-related leaks and frozen pipes.

Denton plumbing questions
How do I know if my Denton 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 Denton: Expansive clay swells and shrinks, stressing pipes under slab foundations.
Who can thaw a frozen pipe in Denton?
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 Denton: Hard freezes catch attic and exterior-wall pipes off guard.
Which lakes supply Denton's tap water?
Lake Lewisville, the primary source, and Lake Ray Roberts, both treated at city plants.
Why do Denton slab leaks happen after drought?
Expansive clay shrinks in dry spells and swells after rain, moving the foundation and stressing pipes underneath. Watering the foundation perimeter evenly helps limit movement.
I rent near UNT. What do I do when a pipe freezes?
Open the faucet, warm the area gently, never with an open flame, and tell your landlord right away; if it has burst, shut off the main first.
Are older homes near the Denton square prone to sewer problems?
Yes. Older laterals in that area are often clay or cast iron, and shifting soil cracks joints. A camera inspection before buying is worth it.
