Slab foundations on shifting soil
Homes are mostly built on slabs, and the clay and limestone soils move with wet and dry cycles. Slab leaks show up as warm floors, damp baseboards or a water bill that jumps for no reason.
Round Rock grew fast from the 1990s on, with Brushy Creek running through the middle of the city. 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.

More than half homes in Round Rock were built in 2000 or later, and about a third 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 are on slabs, and newer plumbing means leaks usually start at connections and appliances.

Most homes in the Austin suburbs have the main shutoff in the meter box near the curb, with a house valve in the garage or on an outside wall near where the line enters.
If the water came from a toilet, a sewer line or outside, treat it as contaminated: see sewage backup cleanup or flood water cleanup.

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.

Independent restoration companies we connect callers with cover these Round Rock 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.
Yes. Most Round Rock 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.
Calls from 78664, 78665, 78681 are routed to independent restoration companies that serve those ZIP codes. We are a referral service and don't do the work ourselves.
Say where the water came from and how long it has been wet. That's usually enough to plan the next step.
