Hail, wind-driven rain and flash runoff
March through June brings the region's severe thunderstorms. Hail-damaged roofs and clogged gutters push water into attics and ceilings, often days after the storm when the next rain arrives.
Lewisville sits on the south shore of Lewisville Lake. This page covers what usually causes water damage here, what to do in the first hour, and how to reach an independent restoration company that serves your ZIP code.

About half homes in Lewisville were built in the 1980s and 1990s. Some homes from that period were plumbed with polybutylene, a gray plastic pipe used until the mid-1990s that is known for failing at the fittings. If you see gray pipe at the water heater or under sinks, have it checked.
If the water heater is original or close to it, look at the base for rust or moisture. A failing tank usually leaks a little before it lets go.
Because homes here are built on slabs, a leak inside a wall or under the floor shows up late: a warm patch, a cupped board or a stain at the base of the wall.
About 36% of homes in Lewisville are in buildings with five or more units. In apartments and condos, water from one unit often reaches the unit below, so tell management or the HOA right away. The building's master policy and your own unit or renters policy may each cover a different part of the damage.
Half of its homes were built in the 1980s and 1990s, and a large share are apartments and townhomes where one leak can reach the unit next door.

Most Dallas–Fort Worth homes have the main shutoff in the city meter box near the street, plus a house valve on an exterior wall or in the garage. A meter key or a long flat screwdriver opens most meter lids.
If the water came from a toilet, a sewer line or outside, treat it as contaminated: see sewage backup cleanup or flood water cleanup.
Housing age is fairly even across these ZIP codes, with median build years between 1994 and 1995. Older ZIP codes tend to see more corroded pipe and drain failures; newer ones more appliance and fitting leaks.

Standard Texas homeowners policies generally cover sudden water damage, such as a burst pipe, but not rising floodwater, which needs a separate flood policy through the NFIP or a private insurer.
The Texas page covers state insurance rules in more detail, and our claims guide explains how to document a loss.
Each guide below explains one kind of water damage and how it is handled.
Independent restoration companies we connect callers with cover these Lewisville ZIP codes:
Start within 24 to 48 hours; the EPA says materials dried in that window are much less likely to grow mold. Hidden moisture inside walls and under floors needs meters and drying equipment to find and remove.
Worn supply lines, original shutoff valves, aging water heaters and, in some homes, polybutylene pipe. These parts tend to fail gradually, so a small leak can go unnoticed for weeks.
