1. Check windows and doors for drafts and leaks
Cold air pushing into your home is obviously not ideal. To check for drafts, try a candle test: Follow along the frame of your windows with a lit candle. If the flame flickers (or gets blown out), that means you have air seeping in. “You won’t ever be able to seal your home up 100 percent,” says Thompson, “but you shouldn’t have gusts.” Similarly, you shouldn’t be able to see light if you get on your hands and knees and look under your front door. “The key here is sealing up these gaps,” says Dianna Davis-DePinto, an Associate Merchant who works with Thompson on all things windows at The Home Depot. As bad as wind is, moisture can be even worse. Because water can cause rotting and serious damage if it gets into your walls.
To guard against both wind and moisture, the experts suggest caulking up gaps and adding weather stripping wherever possible. These aren’t perfect solutions, but they’re great stopgaps to put in place until you decide to get new windows or doors.
