San Antonio doesn’t see freezes often, but when it happens, it hits hard. Pipes here aren’t built for long stretches of cold, which is exactly why freezes cause so much damage across South Texas. A burst pipe can flood your home in minutes and the cleanup is never cheap.

Here’s the thing. A little prep goes a long way. If you live in San Antonio or the surrounding areas, these steps can help protect your plumbing before and during a freeze or ice warning.

Why Freezes Are a Big Deal for Texas Plumbing

When temperatures drop below freezing, water inside pipes can freeze and expand. That pressure has nowhere to go, so pipes crack or burst. Often, the damage doesn’t show up until things thaw and water starts pouring out inside walls, ceilings, or cabinets.

Homes in San Antonio are especially vulnerable because many pipes run through exterior walls, attics, or garages without heavy insulation.

How to Prepare Your Home Before the Freeze

1. Insulate Exposed Pipes

Wrap any exposed pipes, especially in garages, crawl spaces, attics, and on exterior walls. Pipe insulation sleeves or even towels secured with tape can make a big difference in a pinch.

2. Protect Outdoor Faucets

Disconnect garden hoses and cover outdoor spigots with insulated faucet covers. If you don’t have covers, wrap them tightly with cloth and plastic.

3. Know Where Your Main Water Shut-Off Is

If a pipe does burst, shutting off the water quickly can prevent major damage. Make sure everyone in the house knows where the main shut-off valve is and that it actually works.

4. Seal Drafts Around Pipes

Cold air sneaking in through gaps can freeze pipes fast. Seal cracks around doors, windows, and where pipes enter the house with caulk or weather stripping.

What to Do During the Freeze

Let Faucets Drip

Keep a slow drip on faucets connected to exterior walls. Moving water is much less likely to freeze than standing water.

Open Cabinet Doors

Open kitchen and bathroom cabinets to let warm air circulate around plumbing, especially under sinks.

Keep the Heat On

Even if you’re leaving town, keep your thermostat set to at least 55°F. Turning the heat off completely is one of the fastest ways to end up with burst pipes.

Use Space Heaters Carefully

If you’re using a space heater to warm a cold area, keep it away from flammable materials and never leave it unattended.

Signs a Pipe May Be Frozen

• Little to no water coming from a faucet
• Frost on exposed pipes
• Strange smells from drains
• Unusual noises when turning on water

If you suspect a frozen pipe, don’t wait. Turning on the water full blast can make things worse once it thaws.

If a Pipe Bursts or Freezes

Turn off your main water supply immediately and call a professional plumber. The faster you act, the more damage you can prevent.
