How to Winterize Your Home for the Upcoming Freeze in San Antonio and Austin, Texas

With freezing temperatures, potential freezing rain, and an Extreme Cold Watch or Winter Storm Warning affecting much of Central Texas this weekend (Friday, January 23 through Sunday, January 25, 2026), now is the time to take proactive steps to protect your plumbing. Even though hard freezes are less common in our region compared to northern states, when temperatures drop below freezing for extended periods—especially with wind chills making it feel even colder—pipes can freeze, burst, and cause significant damage.

PLEASE TAKE THESE STEPS AS TEMPS APPROACH FREEZING! Protect your home from potential pipe freezing and costly damage by following these simple, effective steps:

• Drip your faucets — Let both hot and cold water run in a slow, steady drip (roughly one drop every 2-3 seconds) from all faucets, particularly those on exterior walls or in unheated areas. This keeps water moving through the pipes and helps prevent freezing.
• Open cabinet doors — Leave kitchen and bathroom cabinet doors open (especially under sinks) to allow heated indoor air to circulate around the pipes and keep them warmer.
• Keep the heat on — Maintain your thermostat at no lower than 65°F, even when you’re away from home or sleeping. Consistent indoor warmth is crucial to preventing indoor pipes from freezing, particularly in walls or crawl spaces.
• Wrap your outside faucets — Disconnect and drain all garden hoses completely, then insulate any exposed outdoor faucets or spigots using foam covers, thick towels, or pipe insulation wraps. Make sure the material is substantial enough to provide real protection against the cold.

What Can Happen If You Don’t Winterize Your Home Failing to prepare during a freeze can lead to frozen pipes that expand and burst when the water thaws. This often results in major issues, including:

• Burst pipes — Leading to sudden, high-volume water leaks inside walls, ceilings, or floors.
• Extensive water damage — Soaked drywall, flooring, insulation, and personal belongings, which can promote mold growth if not addressed quickly.
• Flooding — In severe cases, uncontrolled water flow can flood entire rooms or basements.
• Costly repairs — Plumbing fixes, water extraction, mold remediation, and structural repairs can easily run into thousands of dollars, plus potential loss of use if you need to relocate temporarily.
• Additional complications — Damage to electrical systems, appliances, or HVAC if water reaches those areas.

These risks are especially relevant during prolonged sub-freezing conditions like those forecasted, where pipes in uninsulated areas or exterior walls are most vulnerable.

If You Suspect Damage After the Freeze If you notice reduced water pressure, unusual sounds from pipes, wet spots on walls/ceilings, or no water flow at certain faucets once temperatures rise, act quickly. A professional plumber can pressure test your plumbing system to detect hidden leaks or weaknesses caused by the freeze. They can then pinpoint the exact location for accurate, efficient repairs—preventing further damage and helping you avoid bigger problems down the line.
