Had this annoying haze building up between the glass in my living room windows, and it bugged me for ages. I read somewhere you can drill a tiny hole at the bottom corner (carefully!) and stick in some silica gel packs to soak up the moisture. Did that, sealed the hole with clear tape, and honestly it helped more than I expected. Not a perfect solution, but way cheaper than replacing the whole window. Anyone else tried weird hacks like this or found something better?

I’m impressed you went for the drill method. I always chicken out with stuff like that, worried I’ll end up with a bigger mess. I tried using one of those anti-fog sprays on the outside and, honestly, it barely did anything for the haze between the panes. Have you noticed if the silica gel needs swapping out often? I keep wondering if there’s a way to prevent the seal from going bad in the first place, or if that’s just how these older windows go over time.
Funny thing, I’ve seen a bunch of folks try anti-fog sprays and yeah, they really don’t do much for the stuff trapped between the panes. Once that seal’s shot, it’s tough to stop moisture from creeping in. Silica gel can help for a while, but you’ll probably need to swap it out every few months if the window’s still pulling in moisture. As for stopping seals from failing—older windows just seem to go eventually, especially with big swings in temperature. I wish there was a magic fix, but sometimes all you can do is slow it down or patch it up like you did.
Yeah, I’ve tried a couple of those anti-fog sprays myself—waste of money for anything between the panes. Once the seal’s gone, it’s like trying to bail out a boat with a leaky hull. The silica gel trick is clever, but like you said, it’s just buying time. I stuck some packets in one of my worst offenders last winter and honestly, it helped for a bit but then the fog crept back. Maybe if you’re diligent about swapping them out, you can stretch it, but who’s got time to babysit their windows every few months?
Has anyone actually tried those DIY repair kits where you drill a tiny hole and vent the window? I keep seeing them on YouTube but can’t decide if it’s just snake oil or actually worth the hassle. My neighbor swears by them—says he drilled, vented, and sealed his kitchen window and hasn’t had fog since. But I’m not sure I trust his handiwork; he once “fixed” his dryer vent with duct tape and optimism.
At some point, I guess you just have to weigh the cost of new glass versus living with cloudy windows. My place is pushing 40 years old and these double-panes are original, so I’m not shocked they’re giving up. I do wonder if anyone’s found a sealant or patch that actually works long-term, though. Or is it just inevitable that once the seal fails, you’re on borrowed time?
I get what you mean about the anti-fog sprays—tried one on a whim, and it did absolutely nothing for the stuff between the panes. As for those vent kits, I’ve watched a few of those YouTube demos too. They look promising, but I always wonder about long-term issues like mold or if you’re just making another spot for moisture to sneak in. My windows are from the late 80s, so I’m in a similar boat. At some point, I figure the seal’s just done for and anything we do is a stopgap. Haven’t found a sealant that actually lasts, unfortunately.
Yeah, I hear you on the sprays. Tried one last winter and honestly, it was just a waste of ten bucks—didn’t touch the stuff between the panes, just smeared up the outside a bit. The vent kits are interesting, but I’ve got the same worries about mold or even bugs finding their way in. Once the seal’s shot, it feels like you’re just fighting a losing battle.
My house is early 90s, so not quite as old as yours, but those double-panes still aren’t holding up. I tried running a bead of silicone around the outside edge once, hoping to “patch” the seal, but it didn’t last past the first real cold snap. Ended up with even more condensation after a while. Kind of gave up after that.
Honestly, I think you’re right—most fixes at this point are just temporary band-aids until you bite the bullet and replace the glass or full window. Not cheap, but at least then you know it’s fixed for a while. Until then, I just crack the window sometimes or run a dehumidifier nearby if it gets bad. Not perfect, but it helps a little.
It’s frustrating when nothing seems to work long-term. Good to know I’m not the only one dealing with this mess.
I get where you’re coming from about just wanting to replace the whole window, but I’ve actually had some luck with a less drastic approach. If the frames are still solid and it’s just the glass that’s fogged, you can often get a glass shop to swap out just the IGU (insulated glass unit) instead of the entire window. It’s usually quite a bit cheaper and doesn’t mess with your siding or trim. Not saying it’s always perfect—depends on the window design—but it saved me a chunk of change on a couple rentals I manage. Worth checking into before going all-in on full replacements.
Had to chime in here because I’ve wrestled with this exact problem in my 80s-era ranch. First time I saw fog between the panes, I figured I’d need to yank out the whole window and start over, which honestly sounded like a nightmare given the siding situation around my place. But I got curious and started poking around online—turns out, like you said, swapping just the IGU is a thing.
I ended up taking a sash out myself (not as tricky as I thought, though those old wood frames are heavier than they look) and hauled it to a local glass shop. They matched the dimensions and had a replacement ready in about a week. Cost me maybe a third of what a full new window would’ve run. The only hiccup was getting the bead back on without cracking it, but after some swearing and YouTube tutorials, it worked out.
One thing I noticed—if your frames have even a little rot or warping, swapping just the glass might not seal as well as you’d hope. I tried it on another window that had some soft spots in the frame, and that one started fogging again after two winters. Lesson learned: check the wood (or vinyl) carefully first.
It’s not a magic fix every time, but definitely worth looking into before you let anyone talk you into full replacements. And if you’re handy (or just stubborn like me), it’s kind of satisfying to fix instead of replace.
I get the appeal of just swapping the IGU, but in my experience, especially with older houses, it’s not always the most energy-efficient fix long-term. I tried the same route on a couple windows in my ‘70s split-level, but even after replacing the glass, I still felt drafts and noticed my heating bill barely budged. Turns out, the old frames just weren’t up to snuff anymore—lots of air leaks you can’t always see. Sometimes biting the bullet and going for full replacements actually pays off in comfort and savings, even if it stings up front. Just my two cents from chasing lower utility bills for years...
You nailed it—those old frames are sneaky. I’ve swapped out just the glass for folks before, thinking it’d be a quick win, but then you find out the wood or aluminum is warped or the seals are toast. I remember one house where we did all the IGUs and, two winters later, the owner was still layering up indoors. Ended up doing full window replacements the next year and suddenly their place actually held heat. Not always fun on the wallet, but sometimes it’s the only way to really solve those drafty headaches.
