How to Prevent Frozen Pipes in San Antonio Before a Hard Freeze
Quick answer
Before a San Antonio hard freeze: insulate exposed pipes, seal cold-air gaps, protect outdoor faucets, find your main shutoff and know what to do if a pipe freezes.
Insulate pipes in attics, garages and exterior walls, seal gaps where cold air reaches them, disconnect hoses and cover outdoor faucets, and open sink cabinet doors during an extended freeze. Learn where your main shutoff is before you need it. SAWS lists a slow drip as one step during long freezes, but no step guarantees a pipe won't freeze.
Online estimate appointments need at least 24 hours' notice. Need help sooner? Call (210) 880-2864.
Which pipes are most likely to freeze in San Antonio?
Pipes in exterior walls, garages, attics, crawl spaces, outdoor faucets and other unheated areas are the most exposed during a hard freeze.
Should I drip my faucets during a freeze?
SAWS lists letting faucets drip slowly as one step during extended freezing temperatures and notes that the extra water is billed. A drip can help keep water moving, but pipes can still freeze, so insulation, sealing cold-air gaps and knowing your shutoff matter more.
What should I do if a pipe freezes or bursts?
If a pipe bursts, shut off the main water supply right away and keep clear of water near outlets or the electrical panel. For a frozen pipe, never use an open flame; open the faucet and warm the pipe gently with a hair dryer or warm towels, or call a licensed plumber.
