I ended up just taping plastic over the whole window frame until spring. Curious if anyone’s had luck with those shrink wrap window insulation kits?
Shrink wrap kits are actually not bad for what they are—definitely a step up from just taping plastic over the window. The trick is getting that plastic tight and wrinkle-free, which takes a bit of patience (and a steady hand with the hair dryer). They won’t fix a crack, but they do help with drafts and condensation. I wouldn’t call them a permanent solution, but for an old house like mine, they’re a decent winter band-aid. Just don’t expect miracles if your window’s really falling apart...

Honestly, I’ve seen folks slap on those kits over a cracked pane and call it good, but if the glass is actually cracked, you’re better off with a little clear packing tape right on the crack first. The shrink plastic helps with drafts, sure, but it won’t keep the glass from shifting or rattling if it’s loose. Had a customer try just the plastic once and ended up with a mess of broken glass on the floor when the wind picked up... not fun to clean up.

If you’re just trying to buy some time before a full repair, here’s what worked for me: first, clean the glass, then run clear packing tape along both sides of the crack. Press it down well. That keeps the pieces from shifting, like you mentioned. After that, I did use those window film kits over it just to cut drafts. It's not pretty but holds up for a while. Wouldn’t skip the tape step though—learned that the hard way when the wind rattled mine loose.
I get the logic with the tape, but has anyone tried using that clear silicone caulk instead? I’ve patched a small crack with it before and it seemed sturdier than just tape. Wondering if there’s a downside I’m missing—maybe cleanup later?

I’ve used clear silicone for a crack in my bathroom window, and it definitely felt sturdier than tape. The only thing is, cleaning it off later was a pain—left some residue that didn’t want to budge. Still, it kept the draft out way better than packing tape ever did. If you’re not worried about appearances, it’s not a bad fix at all.
Silicone definitely seals better than tape, but it’s a pain if you ever want to remove it. I tried it on a rental once and getting the stuff off without scratching the glass was a headache. Tape looks messier but at least it peels off clean. Guess it depends if you care more about looks or hassle later on.
- Totally agree, silicone seals way better—no contest there.
- Downside is, it’s a nightmare to get off clean. I’ve spent way too long scraping it off old windows.
- Tape’s ugly but you can just peel and toss.
- If it’s a temp fix, I’d go tape every time. For something longer term, maybe silicone… but only if you’re sure you won’t need to touch it for a while.
- Tried clear packing tape once—looked awful but held up through a storm.
- Silicone’s great if you want it to last, but yeah, getting it off is a pain—been there, spent way too long with a razor blade and still found bits stuck in the corners months later.
- For a quick patch, I usually go with duct tape. Not pretty, but it’s tough and actually sticks even if the glass is a bit dirty. Packing tape is alright in a pinch, but it gets cloudy and peels if there’s any moisture.
- If you’re worried about looks, I’ve used that clear Gorilla tape—sticks better than packing tape and doesn’t yellow as fast. Still not invisible, but less ugly than duct tape.
- One thing: if the crack’s big or spreading, none of these will really stop it for long. I had a window spiderweb on me after a cold snap, and tape just slowed the inevitable.
- If it’s a rental or you’re waiting for a replacement, tape’s the way to go. But for anything you care about, I’d skip silicone unless you’re sure you won’t need to mess with it for a year or two.

I’ve had the same luck with duct tape, but sometimes it leaves that sticky residue that’s a pain to clean off later. One trick I picked up: run a hairdryer over the tape for a minute before peeling it off—makes cleanup way easier. Has anyone tried those UV-cured glass repair kits? Curious if they’re worth it for small cracks or just marketing hype.
Honestly, duct tape’s fine for a day or two, but I’ve seen it make things worse—especially if the crack spreads under pressure. Those UV kits? They’re not a miracle fix. For tiny chips, maybe, but anything bigger and you’re just delaying the inevitable. If the glass is double pane or insulated, that stuff’s basically useless. Sometimes a piece of clear packing tape does less damage and buys you time till a real repair.
