KEEPING THE COLD OUT: MY STEP-BY-STEP FOR DRAFT-PROOFING DOORS

aspenskater · 2026-03-28T19:19:36Z

Here’s how I tackled making my old back door less of a wind tunnel last winter. I’m not claiming it’s the “pro” way, but it made a noticeable difference in my heating bill, so maybe it’ll help someone else. First thing I did was check for drafts with that classic candle trick (hold a lit candle near the edges and see if the flame dances). My door was leaking air all around the frame and especially at the bottom—no surprise there. Next up, I grabbed some weatherstripping from the hardware store. There’s like a million types, but I went with the foam tape because it was cheap and honestly, I didn’t want to mess with anything complicated. Peeled and stuck it around the inside edge of the door frame. For the bottom, I used one of those door sweeps you screw in (the adhesive ones always peel off for me after a month or two). After that, I tightened the hinges a bit since the door was sagging and wasn’t closing flush. Didn’t realize how much that mattered until I did it—definitely helped the seal. Last step: I put a draft stopper (just an old rolled-up towel, honestly) along the bottom when it got really cold at night. Not high-tech, but it works. I’m sure there are fancier options out there—like those insulated core doors or whatever—but this was all stuff I could do with basic tools and about $20. Anyone have better tricks, or maybe a way to make it look less like I’m barricading myself in for a zombie apocalypse?

KEEPING THE COLD OUT: MY STEP-BY-STEP FOR DRAFT-PROOFING DOORS

Those double-sided draft stoppers can be a decent workaround, especially for older doors that aren’t exactly square anymore. I’ve used them in a couple of rentals where I couldn’t do any permanent fixes. They’re definitely less hassle than trimming silicone sweeps, but they’re not perfect either—sometimes they slide around or get caught if the floor isn’t level. If you’ve got a big gap on one side, you might still notice a bit of cold sneaking through.

One trick I’ve tried is stuffing a bit of extra insulation (even an old towel) into the tube part before sliding it under the door. Not the prettiest solution, but it helps fill those weird gaps. If you’re up for a little DIY, making your own with pipe insulation and fabric can give you a custom fit. It’s not as sleek as a proper sweep, but sometimes function wins over form when winter hits hard...

- Just went through this with our new place—first winter here and I was shocked at how much cold air sneaks in around the doors.
- Tried those double-sided stoppers too, but honestly, they slid around a lot on our tile. Not a fan.
- Ended up installing a proper door sweep. Took maybe 15 minutes with a drill and it’s way more solid than any of the fabric ones I tried before.
- For the sides, weatherstripping tape did the trick. Cheap and easy, but you’ve gotta clean the frame first or it doesn’t stick.
- Not the prettiest setup, but our entryway is way less drafty now... worth it for the lower heating bill.
