10 Last-Minute Ways to Protect Your Home During Extreme Cold
Chelsea O'Donnell
We’ve spent the last couple of weeks talking about frozen pipes and ice dams, and unfortunately, this weekend is shaping up to be the coldest stretch of the year. When temperatures drop this low, small oversights can turn into expensive problems fast.
The good news? You don’t need to panic or run out and spend a fortune to help your home ride out extreme cold. A few simple, last-minute steps can make a real difference now and help prevent bigger repair bills down the road.
Here are 10 practical things you can do before (and during) a deep freeze.
1. Let faucets drip just a little
A slow, steady drip keeps water moving through pipes, making them far less likely to freeze. Focus on faucets connected to exterior walls, especially in kitchens, bathrooms, and laundry areas.
2. Open cabinet doors under sinks
This allows warm air from your home to circulate around plumbing. It’s simple, free, and surprisingly effective, especially overnight when temperatures hit their lowest point.
3. Turn the thermostat up a few degrees
This isn’t the weekend to save on heating costs. A slightly warmer house helps protect pipes in walls, basements, and crawlspaces. Consistent heat is better than dramatic temperature swings.
4. Check that vents and returns aren’t blocked
Furniture, rugs, or curtains blocking vents can reduce heat circulation, creating cold pockets near exterior walls. Make sure warm air can move freely throughout your home.
5. Seal obvious drafts (temporarily is fine)
If you feel cold air coming in around doors or windows, stop it now. Towels, draft snakes, or temporary weatherstripping can help seal gaps quickly and cheaply until permanent fixes can be made later.
6. Make sure attic hatches are closed and sealed
An open or poorly sealed attic hatch allows warm air to escape, cooling your home and contributing to ice dam formation. Even a quick check can help keep heat where it belongs.
7. Clear snow away from foundations and vents
Snow piled against your house can refreeze and cause ice buildup near foundations. Also check dryer vents, furnace exhausts, and intake pipes to make sure they’re clear and functioning properly.
8. Avoid shutting off heat in unused rooms
Closing doors and turning off heat may seem logical, but it can actually increase the risk of frozen pipes in those areas. Keep temperatures consistent throughout the house.
9. Know where your main water shutoff is
This doesn’t cost a dime but it’s critical. If a pipe does burst, shutting off the water quickly can dramatically reduce damage. If you’re not sure where it is, take five minutes to find it now.
10. Don’t ignore warning signs
Unusual drafts, dripping sounds, frost on pipes, or doors suddenly sticking can all be early indicators of cold-weather stress on your home. Addressing small issues now can prevent major repairs later.
A quick reminder
Extreme cold tests even well-maintained homes. These steps aren’t about perfection, they’re about reducing risk and giving your house the best chance to get through a tough weekend unscathed.
If you’ve already dealt with ice dams, frozen pipes, or winter damage in the past, it may be worth having a professional take a look once temperatures rise. Preventative maintenance is almost always cheaper than emergency repairs.
Stay warm, stay safe, and let’s all get through this cold snap without any surprise phone calls to our insurance companies.
