If you’ve lived in North Texas for more than a few winters, you remember February 2021. For most of us, that storm rewrote what we thought a Texas winter could do — and it left a lasting habit of glancing at the forecast a little more carefully when the temperature starts to drop.

Here’s the good news, especially if you’re in a newer home: a recently built house is one of the best-prepared structures on the block when a freeze rolls in. Modern insulation, tightly sealed windows and doors, and current building practices give your home a real head start. Your job is simply to handle the exposed edges — the outdoor faucets, the irrigation, and a few smart habits during the freeze itself. This checklist walks you through all of it.

Before the Freeze: Do These Now

The best freeze prep happens on a calm, mild day — not when sleet is already falling. Knock these out once and most of them carry you through the whole season.

Find and test your main water shut-off valve

This is the single most important thing to do before you ever need it. If a pipe bursts, shutting off the water fast is what stands between a minor fix and a flooded living room. Locate your main shut-off valve now, and turn it on and off once to confirm it works and isn’t stuck.

Where to look: In Texas, the valve is often in a box in the front yard near the street, but it may also be in the garage, near the water heater, or in another accessible interior spot. Keep the area around it clear so you’re not moving boxes in an emergency.

Handle outdoor faucets, hoses, and irrigation

•      Disconnect, drain, and store garden hoses so the connected spigot can drain fully.

•      Cover exterior faucets with insulated faucet covers from any hardware store.

•      Shut off your irrigation controller, or make sure it has a working rain/freeze sensor. In North Texas, fully draining buried irrigation lines usually isn’t necessary — but the controller should not be running during a freeze.

Insulate anything exposed

Walk your garage, attic access, and any spots where plumbing runs along an exterior wall. Foam pipe sleeves or insulating wrap on exposed lines add cheap, effective protection in the few places your home’s built-in insulation doesn’t reach.

When a Freeze Warning Hits

Once a hard freeze is in the forecast, shift into a handful of simple habits. None of these are dramatic — they just keep water moving and warm air circulating.

•      Keep your thermostat steady. Resist the urge to drop it overnight. A slightly higher heating bill is far cheaper than a burst pipe.

•      Open cabinet doors. Under sinks on exterior walls, open the cabinets so warm room air reaches the plumbing.

•      Let faucets drip. A slow drip from both the hot and cold taps relieves pressure. Prioritize the faucet farthest from your main valve and any along exterior walls — you don’t need every faucet in the house running.

•      Don’t close off rooms. Leaving interior doors open helps the whole house hold an even temperature.

The New-Build Advantage

Here’s where a newer home genuinely works in your favor. Older Texas houses — and especially homes raised off the ground or with aging, thin insulation — are the ones that tend to make the news during a freeze. A current build is a different story.

Pipes inside well-insulated walls generally stay safe down to far colder outdoor temperatures than exposed lines, which can begin to freeze much sooner. Modern wall and attic insulation, tightly sealed windows and doors, and frost-resistant exterior fixtures all mean your home is doing a large share of the work for you. Your role is to protect the handful of exposed points — outdoor faucets, irrigation, and any plumbing in unconditioned space — and to keep heat moving on the inside.

Put simply: your home gives you margin. Use these steps to extend it.

If a Pipe Does Freeze

Even with good prep, an extreme cold snap can occasionally win. If you turn on a faucet and only a trickle comes out, act calmly:

•      Shut off the main water valve if you suspect a pipe has already cracked — this prevents water from gushing out once it thaws.

•      Thaw exposed pipe gently with a hair dryer on a low setting, working back and forth along the pipe. Never use a torch or open flame.

•      Keep the faucet open while thawing so water and pressure have somewhere to go.

•      Call a licensed plumber for any pipe you can’t see or reach, or for any repair beyond a simple thaw.

A Quick Word on Insurance

Worth knowing before the cold arrives: some homeowners policies may not pay for frozen-pipe damage if you didn’t take reasonable steps to protect your pipes — such as keeping the heat on. If you do experience damage, document everything with photos and a written list.

This isn’t insurance or legal advice. Coverage varies by policy, so check your specific homeowners coverage with your provider.

Frequently Asked Questions

At what temperature do pipes actually freeze?

Water freezes at 32°F, but pipes inside insulated walls typically stay safe until outdoor temperatures fall to around 20°F. Exposed pipes — in attics, garages, or along exterior walls — are at risk much sooner, and wind chill speeds it up.

Do I really need to drip every faucet?

No. One or two faucets is usually enough — focus on the one farthest from your main shut-off valve and any along exterior walls. A slow, steady drip from both hot and cold taps is the goal.

Are outdoor faucet covers enough on their own?

They help, but they’re not foolproof during an extended hard freeze. Treat them as one layer of protection alongside draining hoses, insulating exposed pipe, and keeping the house warm — not as your only defense.

Where is my main water shut-off valve?

Often in a box in the front yard near the street, but check the garage and the area near your water heater too. Locate and test it before a freeze so you’re not searching for it in an emergency.

A little preparation goes a long way. Save this checklist, tackle the “before the freeze” items on the next mild afternoon, and your new home will handle the rest.
