Most San Angelo winters are gentle. We get long stretches of sunny, mild days, and it's easy to assume freezing pipes are a problem for places farther north. That assumption is exactly what makes a hard freeze so damaging here — our homes, plumbing, and habits simply aren't built around it.
When a strong arctic front pushes down into West Texas and temperatures drop well below freezing for a day or more, pipes that have never given trouble can freeze, expand, and split. A little preparation before the cold arrives is the difference between an uneventful night and water pouring through your ceiling.
Pipes burst because water expands as it freezes. When the water inside a line turns to ice, it pushes outward with enormous force. If that pressure has nowhere to go, the pipe cracks or the fitting fails. The break often isn't obvious until the ice thaws — then the split line releases water, sometimes hundreds of gallons, into your walls and floors.
Because hard freezes are uncommon here, many local homes have plumbing that's more exposed than it would be in a colder climate. Pipes may run through unheated garages, attics, exterior walls, or crawl-adjacent areas with little or no insulation. Outdoor spigots, sprinkler lines, and pipes in the garage are usually the first to freeze. The homes most at risk are the ones nobody worried about because the pipes were "always fine."
The best protection happens before the cold front arrives. When you see a hard freeze in the forecast, take a few simple steps:
Moving water is much harder to freeze than still water. On the coldest nights, let a faucet — especially one on an exterior wall — drip slightly. That small, steady trickle relieves pressure and helps keep the line from freezing solid.
Open the cabinet doors under sinks so warm indoor air can reach the plumbing, particularly on kitchen and bathroom walls that face outside. Keep your heat on and set to a consistent temperature, even overnight and even if you're leaving town. Dropping the thermostat too low to save energy is a common way pipes end up freezing while no one's watching.
If you're going to be away during a hard freeze, consider shutting off the main water supply and draining the lines so there's nothing left to freeze and burst while the house is empty.
If you turn on a faucet and only a trickle comes out, you likely have a frozen line. Keep that faucet open — as the pipe thaws, the running water helps melt the ice. You can apply gentle warmth with a hair dryer or a space heater kept a safe distance from anything flammable. Never use an open flame to thaw a pipe.
If a pipe has already burst, shut off your main water supply immediately, then cut power to any affected areas if water is near outlets or the electrical panel. Move belongings out of the water and start documenting the damage. The faster the water is stopped and removed, the less it soaks into drywall, flooring, and the sub-floor beneath your slab.
Burst-pipe water spreads fast and often hides inside walls and under floors, where it can feed mold within a day or two if it isn't dried properly. That's why professional cleanup matters. We connect you with local pros for Burst Pipe Repair who stop the spread, then handle Water Extraction and Structural Drying to pull hidden moisture out of your home before it causes lasting damage.
A hard freeze in San Angelo may only come every few years, but when it does, it catches unprepared homes hard. A short checklist run the day before the cold arrives is some of the cheapest insurance you'll ever buy.
