I put a rolled-up towel at the bottom of the bedroom door to keep the warm air from escaping. Not glamorous, but it works better than those noisy vent fans.
Funny you mention that—my “door snake” is literally an old pair of jeans stuffed with socks. Not pretty, but it does the trick. Have you checked for drafts around your outlets or window frames? I found a shocking amount of cold air sneaking in through those tiny gaps. A little foam gasket behind the outlet covers made a bigger difference than I expected. Anyone else tried those window insulation kits? They look weird but actually helped me a bit last winter.
I’m a big fan of those window insulation kits, even if they make the windows look like shrink-wrapped leftovers. They’re cheap, and the difference in draftiness is noticeable. I’d argue they’re more effective than just blocking the door, honestly. Outlet gaskets are underrated too—most people don’t realize how much air leaks through those tiny gaps. If you want to get technical, even a thermal camera app on your phone can help spot cold spots you’d never expect. It’s wild how much energy gets wasted through little cracks and gaps.
I’ve crawled under more houses than I care to admit, and you’d be surprised how much cold air sneaks in through spots nobody thinks about—like the gaps around plumbing pipes or even under baseboards. Outlet gaskets are a game changer, but I’d also check around any pipes or vents that go outside. One winter, I found a draft coming straight through a bathroom vanity because the builder never sealed the pipe cutout. A little expanding foam made a huge difference. Sometimes it’s the weirdest spots that make the biggest impact.

That’s spot on. I’ve seen folks overlook dryer vent exits and even the gaps behind tubs—those can leak a ton of air. Caulk and foam go a long way, but don’t forget to check for missing insulation around rim joists too. It’s not always just the obvious spots.

Couldn’t agree more about rim joists—people miss those constantly. But honestly, I’d put money on leaky electrical boxes too. I’ve pulled off outlet covers and felt a straight-up draft. Quick fix: foam gaskets behind the plates. Not glamorous, but it works.
