Frozen Pipes in Texas: What to Do First

Texas is not known for cold weather, and that is exactly why a hard freeze causes so much damage here. Pipes in many Texas homes run through attics, exterior walls, and unheated spaces, because the climate rarely demands otherwise, and when temperatures drop below freezing for a sustained period, the water inside those pipes can freeze, expand, and split the pipe. The burst often happens not while the pipe is frozen, but when it thaws, and the water that follows can flood a home before anyone notices.

This guide covers what to do first when a freeze has burst a pipe, or when you suspect one has. It is general guidance, and it makes no claim about any specific freeze event or any specific place. The steps are the same ones that apply to any burst pipe, with a few points that are particular to cold weather, and they are worth knowing before the temperature drops rather than after.

How a Texas freeze can burst pipes

When water freezes, it expands, and that expansion puts pressure on the pipe around it. A pipe does not usually split at the frozen section itself; it splits at a weaker point nearby, where the pressure has built up. In Texas, the pipes most at risk are the ones in attics, in exterior walls, in garages, and in any space that is not heated. A short cold night may not be enough to freeze a pipe, but a sustained freeze, especially one that lasts through the day as well as the night, gives the cold time to reach pipes that are normally protected by the warmth of the house.

The damage often becomes visible only when the thaw comes. While the pipe is frozen, the ice blocks the flow, and there may be little or no water to see. When the ice melts, the water flows again, and it flows out through the split in the pipe. That is why a home can seem fine during the coldest hours and then flood in the morning, when the temperature rises. If you return to a home after a freeze and find water where it should not be, a burst pipe is a likely cause, and the first steps are the same as for any burst.

Shut the water off if it is safe to do so

If you find water from a burst pipe, or if you suspect a pipe has burst, the first step is to shut off the water supply. Find the main shut-off valve, which in many Texas homes sits where the water line enters the house, in a utility area, or in a ground-level box near the street, and turn it clockwise until it stops. If the valve is in a dry area that you can reach without stepping into standing water, shut it off now. Stopping the flow is the single most useful thing you can do, because the water will keep coming until the supply is closed.

Do not wade through standing water to reach a valve, and do not touch a valve that is wet or sitting in water. If you cannot reach the shut-off safely, leave it and call for help. A professional can isolate the supply on arrival, and your time is better spent keeping people out of the water and moving belongings to dry ground. It is worth knowing where your main shut-off is before a freeze is forecast, because searching for it while water is spreading is the worst possible time to learn.

Do not touch electrical items in standing water

A burst pipe from a freeze can put water in places you would not expect, including inside walls and ceiling spaces where wiring runs. Water dripping from a ceiling can reach a light fitting, water running down a wall can reach an outlet, and water pooling on a floor can reach the base of an appliance. Do not touch any electrical item, switch, or outlet that is wet or that sits in standing water. Do not step into standing water to reach a switch, and do not switch the power back on if it has been turned off.

If water is near any electrical fitting, stay out of the water and call for help from a dry place. If you can shut the power off safely from a dry place, that is a sensible step, but never wade in to do it. The same rule applies after a freeze as after any other burst: if the water is anywhere near electricity, stay out, and let a professional make the area safe. This is not a step to improvise, and it is not worth the risk of trying to save an appliance or a switch.

Call a professional, and what happens after

Once the water is stopped and the area is safe, call a professional. The visit usually starts with an inspection, including the places water hides, such as inside walls, in ceiling spaces, and under floors, and then moves to water removal, drying, cleaning, and repair. A freeze can burst more than one pipe, so the inspection covers the whole pipe run rather than only the place where water is visible. The scope of the pipe work itself is a matter for the operator to confirm, and the restoration work that follows is the water damage the burst caused.

Before the visit, write down what you noticed and when, and take photographs from a dry place. Note whether the water appeared during the thaw, which rooms are affected, and what you have already done. If you are in the Corpus Christi area, water damage restoration in Corpus Christi follows the same sequence as anywhere else in Texas, and the same first steps apply. For the pipe and the damage it caused, burst pipe water damage repair is the service that covers the job, and flood damage cleanup is the service that deals with the water the burst released.

Preparing for the next freeze

A freeze that bursts pipes is easier to prepare for than it is to deal with afterwards, and the preparation is mostly a matter of knowing your house rather than buying anything. The most useful step is to know where your main shut-off valve is, and to check that it turns, because the valve is the first thing you will need when a pipe bursts, and a valve that is stuck is no use in an emergency. It is also worth knowing where the pipes in your house run, especially the ones in the attic, in exterior walls, in the garage, and in any space that is not heated, because those are the pipes most at risk when the temperature drops, and knowing where they are helps you check them after a freeze and helps the inspector find them if one bursts.

After a freeze, it is worth checking the house even if nothing seems wrong, because a burst pipe does not always announce itself immediately. Look for water where it should not be, listen for the sound of running water when all the taps are off, and check the water meter to see whether it is moving when everything is off. Check the attic, the rooms under it, and the walls that carry the main pipe runs, and look for stains, damp, or a musty smell that was not there before. If you find any of those, the first steps are the same as for any burst: shut the water off if you can do it safely from a dry place, keep people out of standing water, do not touch any electrical item that is wet, and call a professional. A freeze is a general risk in a Texas winter, and the preparation is general too, but the response to a burst is always the same, whatever the weather that caused it.

Your Next Step

If this guide matches what you found at home, the next step is a visit — not a guess. Call and describe what you found, and the visit is arranged from what you describe. The Burst Pipe Water Damage Repair page explains what that service covers, and the flood damage cleanup page explains how flood water is removed and the rooms are dried.

Do not step in standing water near electrical outlets or appliances while you wait, and if water is still coming in, turn off the shut-off valve for that fixture where you can reach it safely.

Keep the guides on this site bookmarked: the first guide, the signs guide, and the preparation guide cover the checks worth repeating — after moving in, and after bringing used appliances home.
