Quick tricks for holding a cracked window together?

Caulk definitely does the trick in a pinch, but man, getting it off later is such a hassle. I tried clear packing tape once when I was desperate—looked terrible, but kept the cold out for a bit. Honestly, I always end up just living with the crack until I can swap the glass. Guess I’m lazy, but as long as it’s not letting in rain or critters, I just throw a curtain over it and call it good.

I totally get the curtain trick—been there. My first winter in this place, I had a cracked window in the guest room and just stuck a poster over it. Not exactly Martha Stewart, but hey, it worked (sort of). I did try duct tape once, thinking it’d be less obvious than packing tape, but it left this nasty residue that took forever to scrub off. Lesson learned: quick fixes are great until you have to undo them.

Honestly, unless the crack is huge or letting in a draft that makes your toes go numb, I’m team “ignore it till you can actually fix it.” I feel like half of homeownership is just figuring out which problems you can live with for a while. That being said, I’d avoid caulk unless you’re really desperate—removing it is a pain and I swear it multiplies when you try to clean it up.

Anyone else tried those plastic window kits? I keep seeing them at the hardware store but haven’t pulled the trigger.

That’s honestly the most accurate thing I’ve read in a while. I tried one of those plastic window kits last year when we had a cold snap. Not the prettiest solution, but it did help with drafts. The tape they come with is way easier to remove than duct tape, and the shrink-wrap thing is oddly satisfying. Only downside: if you have cats or kids, expect them to poke holes in it eventually.

Yeah, I know exactly what you mean about the shrink-wrap—there’s something weirdly fun about blasting it with a hair dryer and watching it tighten up. I’ve used those window kits in my old apartment, and honestly, they worked better than I expected for blocking out drafts. Not the best look, but way better than freezing.

I will say, I tried using clear packing tape once as a quick fix for a cracked pane, thinking it’d be less obvious than duct tape. It held up for a bit, but eventually started peeling and left behind a sticky mess. If you want something that’s easy to undo later, those window kits are definitely the way to go. They’re cleaner to remove and don’t leave residue.

If you’re worried about kids or pets poking through, I’ve seen people layer a thin sheet of plexiglass over the plastic. Not super elegant, but it takes more effort to break through both layers. Or you could try putting a piece of cardboard on the inside as a temporary barrier—ugly but effective.

I agree with you on “figuring out which problems you can live with.” Sometimes it’s just about buying time until you can afford the real fix. My only suggestion: if the crack is spreading fast or you see condensation inside the glass, might be worth prioritizing before it gets worse.

Anyway, nice work improvising. There’s no perfect hack for this stuff—just whatever works until you can get a proper repair.

Honestly, I get the appeal of the shrink-wrap kits, but for me they always felt a bit flimsy.

Silicone caulk definitely holds up better than tape in my experience—especially if you’re dealing with an older wood sash where nothing ever seems to stick right in the winter. I’ve patched a few cracks that way for clients waiting on custom glass, and it’s surprisingly effective. Only thing I’d add is to watch for drafts around the edges; sometimes the caulk seals the crack but not the frame. For a quick fix, I’ve even used packing tape inside and caulk outside... not pretty, but it’ll get you through a cold snap.

That’s a solid approach, honestly. I’ve had decent luck with silicone too, especially in those drafty old windows where nothing wants to bond in the cold. The packing tape trick isn’t pretty, but it does buy you time. I’d just add—if you’re worried about condensation, keep an eye on any moisture building up between the layers. Sometimes it sneaks in and makes things a bit messier than expected... but as a stopgap, hard to beat for the price.

I get the appeal of silicone and tape for a quick fix, but I’ve actually had mixed results with silicone in really cold temps—it sometimes doesn’t cure right if you’re below freezing. If you want something a bit sturdier, I’ve found that using clear epoxy (the two-part kind) can give a stronger temporary seal on the crack itself, especially for single-pane glass. It’s not ideal for big gaps or drafts, but it does hold things together better than tape, and you don’t risk as much moisture sneaking in between layers. Downside is it’s more permanent—removal can be tricky without leaving residue. Just my two cents from battling ancient windows in a 1920s house...

That’s the one thing that always makes me hesitate with epoxy. I used it on a bathroom window crack last winter and let’s just say, getting it off in spring involved a lot of scraping and some new creative vocabulary. For drafts, I’ve actually had decent luck with that plastic shrink film—looks a bit goofy, but it keeps the cold out until you can replace the pane. Old windows really do keep you on your toes...

Shrink film is underrated, honestly. I tried the tape-on stuff one year and it peeled off in a week—condensation city. The plastic kind with the hairdryer actually held up all winter, even with my kids poking at it. Looks weird from the street, but beats frostbite. Epoxy is just too much commitment for me unless it’s a last resort... and yeah, removal is its own adventure.
