Winterizing your home in Dallas isn’t about snowstorms. It’s about the handful of hard freezes we get each year, plus the one bad one that shows up without warning. I’ve been running The Smart Fix across DFW long enough to remember February 2021. We fielded calls for six straight weeks after that one. Burst pipes in Lakewood. Collapsed ceilings in Oak Cliff. Soaked crawlspaces in Preston Hollow. None of those homes had been winterized for a hard freeze.
This is the checklist I give my own family and the one I walk our techs through every October. Ten items. None of them take a full day. Most of them pay for themselves in one cold week.
Why Dallas winterizing is different
Most years we get three or four nights below 25°F and that’s it. Then every decade or so, an Arctic front parks over North Texas for ten straight days and every pipe that isn’t protected fails at the same time.
Your house was likely built for the average year, not the bad one. Add North Texas clay soil that shifts with every rain and freeze cycle, and you end up with gaps you can’t see until water is running through them. This list closes those gaps.
1. Insulate exposed pipes
Any pipe running through an attic, crawlspace, or unheated garage gets wrapped. Foam pipe sleeves from any hardware store cost about $2 per six-foot section. For the worst cold, add heat tape on the sections closest to exterior walls. The 2021 freeze showed us that even interior walls on the north side of a house can freeze if the insulation behind them is thin.
Outdoor hose bibs get their own covers, sold for about $5 each. Do this before the first freeze warning, not during one.
2. Know where your main water shutoff is
I ask every customer who calls during a freeze, “Where’s your shutoff valve?” About half don’t know. If a pipe breaks while you’re at work, the difference between a $400 repair and a $40,000 claim is how fast someone cuts the water.
Find yours now. It’s usually in a concrete box near the curb or inside the garage. Turn it off and on once to make sure it isn’t seized.
3. Seal air leaks around windows and doors
Stand inside with a lit candle on a windy day. Move it along every window and door frame. If the flame flickers, you have a leak. Common fixes are fresh weatherstripping on doors (about $15 a kit) and new caulk around window trim ($8 a tube). Pay special attention to attic hatches and the gap under exterior doors. Those are the two biggest heat thieves in most Dallas homes.
We see this on maybe one in three calls across the metro. Weatherproofing a whole house usually runs $350 to $700 and knocks 10% to 20% off a winter energy bill.
4. Service the heater before you need it
Have a licensed tech run through your furnace or heat pump in October or early November. They check the igniter, blower, filter, and gas connections. The service call is $90 to $150. A dead furnace on a Friday night in January is a $400 emergency call, if you can get one booked at all.
Swap your filter every 60 days during heating season. A clogged filter forces the system to work harder and fail sooner.
5. Clean the gutters
North Texas oaks drop leaves late, sometimes into early December. Clogged gutters hold water, water freezes, and freezing water pulls gutters off the fascia. We repair a lot of gutter damage in February that started in November.
Run water through every downspout to confirm it drains at least five feet from the foundation. If it doesn’t, add a splash block or flex extension. With clay soil, water pooling near the slab is the fastest way to crack interior drywall.
6. Drain the sprinkler system
Shut off the irrigation supply. Open every zone briefly through the controller to relieve pressure. Drain the backflow preventer if you have one above ground. A cracked backflow costs $250 to $500 to replace and always fails on the coldest weekend of the year.
7. Check the attic insulation
In Dallas, you want R-38 or better in the attic. A lot of homes built before 1990 have R-19 or less. You can check yourself. If the insulation is level with or below the joists, it’s too thin.
Blown-in insulation runs $1.50 to $2.50 per square foot installed. A 1,500 square foot home pays back the upgrade in two to three winters through lower heating bills.
8. Test every smoke and carbon monoxide alarm
Use the test button on each unit. Replace any older than ten years. Swap batteries in every alarm, even hardwired ones with backup cells. Winter is peak season for CO incidents in Dallas because people run space heaters and gas fireplaces more. A $25 alarm is cheap insurance.
9. Inspect the fireplace
If you use it, have it swept and inspected once a year. A chimney sweep and inspection runs $150 to $300. Creosote buildup is what starts chimney fires. A dirty damper lets cold air pour straight into your living room all winter.
10. Build a freeze kit
Every Dallas home should have a small winter kit in one spot: flashlight, batteries, a space heater, a 15-amp extension cord, a roll of heat tape, hose bib covers, and a few bottles of water. When a hard freeze gets forecast, you don’t want to be at Lowe’s with everyone else in your neighborhood.
Dallas timing to aim for
Start in early October and finish by November 15. That gives you a full month before the first real cold front. Hard freezes in Dallas usually hit between December 20 and February 15. Any work done inside that window costs more and takes longer, because every handyman, plumber, and HVAC tech is already booked solid.
When I was doing real estate inspections, the homes that handled freezes well were always the ones where the work got done in fall. The ones that got hit were always the ones where someone said, “We’ll deal with it later.”
Ballpark cost for the whole list
A homeowner doing this themselves spends $200 to $400 on materials. Hiring help for the parts that matter most (sealing, insulation top-up, gutter clean, furnace service) runs $800 to $1,500 total. In Dallas our average job comes in around $985, which lines up with roughly four of these items combined.
FAQ
What temperature should I drip faucets at in Dallas?
Start drips when the overnight low hits 25°F or lower, especially on faucets along exterior walls. A pencil-thin stream is enough. Drip every hot and cold tap separately.
Do I need to winterize if I only live here part-time?
Yes, and more carefully. Set your thermostat no lower than 55°F, shut the water off at the main, and open cabinet doors under sinks. A friend or property manager should check the house every few days during a freeze.
How long does winterizing take?
Eight to twelve hours of work if you do it yourself. Most of that is gutters and air sealing. A handyman can knock out the same list in four to six hours depending on the house.
Is it too late to winterize in December?
No. Prioritize pipe insulation, hose bib covers, furnace service, and sealing the biggest drafts. Skip bigger projects like attic insulation until spring.
Will my homeowner’s insurance cover a burst pipe?
Usually yes for the water damage, not the pipe itself, and only if the house was being heated. Most policies require you to maintain heat at 55°F or higher. Read your policy before the first freeze.
