Flat ground and slow drainage
The region is flat, with clay soils that drain slowly. Heavy downpours back up in streets and yards and can push water under doors or into garages within an hour.

What Katy's homes say about water damage
About two in three homes in Katy were built in 2000 or later, and about four in ten since 2010. Newer plumbing rarely fails from age. Water damage in these homes usually starts at a connection: a washing machine hose, a toilet or faucet supply line, an ice maker line, or a fitting that was never quite tight.
Upstairs laundry rooms are common in newer two-story homes, and a burst washer hose there runs straight into the ceiling below. A drain pan and braided steel hoses are cheap insurance.
Most homes in the area sit on concrete slabs, so water from a leak spreads sideways under flooring and into walls rather than draining away. It can soak carpet pad, laminate and the bottom of drywall several rooms from where it started.
Most homes here were built after 2000, and many neighborhoods flooded during Hurricane Harvey.

If water is coming in right now
- Stop the water. Close the valve at the fixture, or the main shutoff for the house.
- Make it safe. Cut power to wet rooms at the breaker only if you can reach the panel without standing in water.
- Protect what you can. Lift furniture off wet carpet with blocks or foil under the legs, and pull rugs off the floor so they don't stain or trap water.
- Photograph it, then get drying started. Photos come first for insurance; drying should begin the same day. Our first 24 hours guide has the full checklist.
Where the main shutoff usually is
Most Katy-area homes have the main shutoff in the meter box near the street, with a house valve usually in the garage or on an exterior wall.
If the water came from a toilet, a sewer line or outside, treat it as contaminated: see sewage backup cleanup or flood water cleanup.

Who pays in Texas?
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.

Water damage questions from Katy
How quickly does water damage need to be dried in Katy?
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.
Can a newer home in Katy still have hidden water damage?
Yes. Most Katy homes are newer, and their leaks usually start at connections: appliance hoses, ice maker lines, water heater fittings and supply lines. Water can travel under flooring and inside walls for days before a stain or soft spot appears.
