Will My Pipes Freeze Tonight? Round Rock TX Pipe Freeze Risk Tool
Round Rock rarely gets harsh winters, but when a hard freeze arrives, Central Texas homes are especially vulnerable because local pipes have little insulation and homes are not built to buffer sub-freezing air. Winter Storm Uri in February 2021 caused widespread pipe damage across Williamson County because local construction simply is not designed for sustained freezing temperatures. This tool tells you when to act and what to do.

Frequently Asked Questions
At what temperature do pipes freeze in Texas homes?
Water starts to freeze at 32 degrees, but pipes in heated interior walls rarely freeze until temperatures drop below 20 degrees. Pipes in unheated spaces, exterior walls, crawl spaces, or outdoor hose bibs can freeze at 28 degrees or below, especially after six or more hours of sustained cold. Central Texas homes are more vulnerable because the pipes have less insulation than homes in colder climates.
How long does it take for pipes to freeze in Round Rock TX?
At 28 to 32 degrees, outdoor or uninsulated pipes can begin to freeze after 6 to 10 hours. At temperatures below 20 degrees, pipes in exposed locations can freeze in 3 to 6 hours. The combination of low temperature, wind chill, and uninsulated pipe location determines actual freeze time for any specific situation.
How do I protect my pipes during a Round Rock freeze warning?
Let cold-water faucets drip at one drip per second. Open cabinet doors under sinks on exterior walls to allow warm air to reach the pipes. Keep your heat at 55 degrees or above even when away. Disconnect garden hoses. Cover outdoor hose bibs with insulating foam covers. Locate your main water shutoff valve before the freeze arrives so you can act quickly if a pipe bursts.
Why did pipes burst in Round Rock during Winter Storm Uri?
Winter Storm Uri in February 2021 brought multi-day sustained freezing temperatures to Central Texas, well beyond what local construction is designed to handle. Round Rock homes, like most in the region, are built for mild winters. Pipes in exterior walls and crawl spaces have little insulation, and the sustained cold overwhelmed whatever protection the structure provided. Many homes that had never experienced a freeze-related failure burst during Uri.
