That thermal camera trick made a huge difference for me too. I thought I’d sealed everything, but when I borrowed one from the library, it lit up the cold air leaks I’d totally missed—especially around the attic hatch and an old phone jack. If you haven’t tried it, it’s worth hunting one down, even just for a weekend.
For those outlets and corners, I’ve had some luck with the foam pads behind switch plates, but honestly, sometimes it’s just a bandaid. What really helped was caulking along the baseboards. It’s not glamorous and takes a bit of patience, but it cut down on those sneaky drafts, especially in the living room where the floor meets the wall.
Crawlspace sealing is a beast, though. Did mine last spring and it was sweaty, awkward work. Used rigid foam board for the rim joists and sealed the seams with spray foam. Not perfect, but my floors felt warmer right away.
It’s like playing whack-a-mole, though—fix one spot and another pops up. Still, every little bit adds up over time.
Honestly, I gotta push back a bit on the foam pads behind outlets. Maybe it’s just my old house (built in the 50s, drafty as heck), but those things never made much of a dent for me. I swear, I could still feel a breeze coming through the living room outlets even after doubling up on pads and caulking around the boxes. Ended up pulling the trim and stuffing bits of mineral wool in the wall cavity—messy, but way more effective.
Crawlspace sealing, though... man, you’re not kidding about it being awkward. I tried to DIY mine last fall and got halfway before running out of patience (and daylight). Still debating if it’s worth hiring someone to finish or just living with slightly chilly floors. Sometimes I wonder if there’s a point where you just accept a little draft as “vintage charm,” you know?
Thermal cameras are fun, but I’ve found the old “back of the hand” trick works in a pinch too—just less high-tech and more “grandpa style.”
I get where you’re coming from about the foam pads not doing much, especially in older homes. But I have to say, in my 70s split-level, those foam gaskets behind the outlets actually made a noticeable difference—at least in the rooms where the exterior wall insulation wasn’t completely shot. I think it really depends on how bad the original air sealing was and what kind of insulation you’re dealing with inside the walls. If you’ve got big gaps or missing insulation, yeah, the pads are just a band-aid.
As for crawlspace sealing, I hear you on the awkwardness. I tried to do mine with a buddy and we both ended up with sore backs and a lot of cursing. Eventually caved and hired someone to finish it, and honestly, the warmer floors were worth every penny. Sometimes DIY just isn’t worth the hassle, especially if access is tight.
Thermal cameras are neat for sure, but I’ll admit I still trust my own senses more than gadgets half the time. Guess there’s something to be said for that “grandpa style” after all…
That crawlspace bit made me laugh—reminds me of the year I tried to insulate under our old addition. Ended up wedged between pipes for half an hour, swearing I’d never do it again. As for those foam pads, I’ll admit I was skeptical, but after a cold snap last winter, I put a few in and swear the draft by the kitchen outlet eased up. Still, nothing beats finding that one sneaky window that never quite shuts right... sometimes it really is just trial and error.
That crawlspace struggle is all too familiar—I've had my fair share of wrestling with pipes and insulation, usually in the middle of winter when you question every life choice that led you there. It's funny how sometimes the simplest fixes, like those foam outlet pads, can actually make a noticeable difference. I used to think they were just a gimmick, but after doing a thermal camera scan for a client last January, I saw firsthand how much air leaks through outlets on exterior walls. Definitely not perfect, but for a few bucks and ten minutes, it’s hard to argue with the payoff.
You hit the nail on the head about windows being sneaky culprits. In older homes especially, settling can throw everything out of square... makes it tough to get a tight seal even if the sash looks closed. I’ve found that sometimes just adjusting or replacing the window stops (the little pieces that keep the sash snug) can help more than weatherstripping alone. Ever tried using incense or a smoke pencil around those problem areas? It sounds silly, but it’s a quick way to spot where air’s getting pulled in.
One thing I’d add: don’t overlook the rim joist area in basements or crawlspaces. People insulate walls and floors but forget that band around the perimeter—huge source of drafts if left bare. It’s not always easy to access (especially with plumbing or wiring in the way), but even stuffing some mineral wool or spray foam up there can make a big difference.
Trial and error is pretty much par for the course with old houses. Sometimes you fix one draft and another pops up somewhere else—it keeps you humble, if nothing else.
That rim joist tip is something I wish I'd known about a few months back. I bought my first place last fall—a 1920s bungalow with a basement straight out of a horror movie. The first cold snap, I swear, it felt like the wind was coming up from the floorboards. I went around with one of those incense sticks (after reading about it online), and the smoke started swirling like crazy right along the edge where the basement ceiling meets the wall. Turns out, previous owners had insulated the walls but left that whole band above the foundation totally bare. I ended up wedging in some leftover Roxul mineral wool and sealing the worst gaps with a can of spray foam. Not the prettiest job, but it actually helped a lot.
I was also super skeptical about those foam outlet gaskets. They just seemed too flimsy to make a difference. But after putting them in along the north wall, I did notice the rooms felt less drafty—maybe not a miracle, but for a couple bucks, I’ll take any improvement.
Windows are still my nemesis, though. The sashes look shut, but somehow I still get that little whistle on windy nights. I tried the smoke trick there too, and sure enough, a couple spots lit up. I fiddled with the stops and added some weatherstripping, but it’s still not perfect. I’m starting to think it’s just an old house thing, and maybe there’s only so much you can do without totally replacing the windows (which isn’t in my budget right now).
It’s almost like every time I fix one draft, another one pops up somewhere else—kind of like playing whack-a-mole with cold air. Still, there’s something satisfying about hunting them down and knowing you made it just a little cozier.
Drafts around old windows are a headache I see a lot. I’ve worked on plenty of homes from the 1920s and it’s always a mix of charm and challenge. Even after adding weatherstripping and adjusting stops, there’s often still some movement—those old sashes just never seal quite like new units. I’ve had luck using rope caulk for temporary fixes in the worst spots; it’s not pretty, but it can knock down those whistles in winter. Full replacement does make a big difference, but yeah, the cost can be rough. There’s a certain satisfaction in chasing down all the leaks, even if you know you’ll be at it again next season.
I hear you on the rope caulk—I've used it too, especially on the upper sashes that never seem to sit flush. One thing I tried last winter was the shrink-wrap window film kits. Not the prettiest, but they actually cut down the draft a lot. Have you ever messed with those, or do you find they just get in the way if you want to open the window?
Shrink-wrap window film is one of those things I kinda rolled my eyes at until I finally tried it. You’re right, it’s not going to win any beauty contests, but it actually worked better than I expected. My living room has these old single-pane windows, and last January the drafts were brutal. The film made a noticeable difference—room felt way less chilly.
Only downside for me was exactly what you mentioned... once it’s on, that window’s not opening till spring unless you want to redo the whole thing. If you’ve got windows you never open in winter anyway (like my guest room), it’s a no-brainer. But for anything you want to crack open for fresh air, yeah, it’s a bit of a pain.
Still, for the price and how easy it is to put up, I’d say it’s worth dealing with the plastic look for a few months. Kinda funny how something so simple can make such a difference.

- Totally hear you on the "not going to win any beauty contests" part. Function over form sometimes, right?
- You nailed it—it's a simple fix that really cuts down drafts for not much money or effort.
- That "once it’s on, that window’s not opening till spring unless you want to redo the whole thing" is the one real catch. I tell folks to pick windows they don’t need to open, just like you did.
- For old single-pane windows, it's honestly one of the fastest ways to make a room more comfortable without a big investment.
- If you ever decide to upgrade those windows down the road, you'll probably notice an even bigger difference—but until then, this trick is a solid move.
