Local water risks
What causes water damage in Austin and Travis County?
Austin sits in a flash flood prone corridor where Hill Country watersheds, city creeks, and a long cooling season combine. The result is a city where outdoor flooding and indoor leaks are both everyday risks.
The Colorado River crosses the metro, and Barton Creek, Onion Creek, and Shoal Creek cut through neighborhoods on their way to it. When heavy rain falls on the steep, rocky watersheds west of town, those creeks rise with very little warning, and low-water crossings and low streets near them flood first. Onion Creek in the south has a long record of flooding homes in its floodplain, and Shoal Creek through central Austin has repeatedly surged through downtown-adjacent streets. Hill Country runoff makes the timing tricky: rain that falls miles upstream can arrive as a creek rise after local skies have cleared. Away from the creeks, Austin homes face slab leaks on shifting soils, water heater bursts, appliance hose failures, upstairs bathroom overflows, and air conditioning condensate clogs during the long cooling season. Hard freezes, including February 2021, add burst pipes to the list.
Speed matters more in Austin than in most Texas cities because creek water is contaminated and indoor water degrades fast in Central Texas heat. Creek and street water that enters a home is treated as Category 3, which means porous materials it soaks are removed rather than cleaned, and the area is sanitized before drying starts. Clean water from a supply line gets the same urgency for a different reason: left standing 24 to 48 hours, it picks up bacteria and becomes a bigger, smellier problem. Our crews classify the water on the first visit and set the protocol from there, so nothing is dried with the wrong method.
The water damage calls our Austin crews answer most often:
- Flash flooding on Barton Creek, Onion Creek, and Shoal Creek after Hill Country rain
- Colorado River tributary rises and low-water crossing flooding
- Slab leaks on shifting Central Texas soils
- AC condensate line clogs during the long Austin cooling season
- Water heater bursts and appliance hose failures
- Upstairs bathroom overflows in two-story homes
- Frozen and burst pipes during hard winter freezes, including the February 2021 freeze
