My double pane window started fogging up, and now I’m stuck between two options: pay a company to just reseal the thing (which is cheaper but I’m not sure how long it lasts), or bite the bullet and replace the whole glass unit. The quotes I got are kinda all over the place, too. Has anyone tried both? Did resealing actually hold up, or was it just a temporary fix?
I’ve been down this road, and honestly, I get why you’re stuck. The resealing thing is pretty tempting since it’s way cheaper upfront, but in my experience, it’s kind of a gamble. I had a company “defog” two windows and reseal them about three years ago—looked fine for maybe a year and a half, then the haziness crept back in. Apparently, once the seal’s blown, moisture finds its way back pretty easily unless the whole IGU (insulated glass unit) is swapped out.
Replacing the glass unit costs more (yeah, those quotes are all over the place—some of mine were double others for no clear reason), but you’re basically getting a fresh start with a new factory seal. If you’re planning to stay in the house for a while or care about energy efficiency, replacement seems to win out in the long run. If it’s just one window and you don’t mind rolling the dice, resealing could buy you time.
One thing I learned: check if your window brand has replacement sashes or IGUs—they can be surprisingly easy to swap if you’re even slightly handy. Just my two cents from way too much time spent on YouTube and home repair forums...
I hear you on the resealing gamble—tried it myself a few years back and had almost the same result. The fix felt temporary, and the fog came creeping back after a while. Swapping out the IGU was more of a hassle upfront (and yeah, those price swings are wild), but I haven’t had any issues since. If you’re handy, like you said, it’s not as intimidating as it sounds. Sometimes just knowing you’ve actually solved the problem for good is worth the extra effort and cash. Hang in there—window stuff’s never as straightforward as you hope.
That’s pretty much been my experience too—resealing felt like putting a band-aid on a leaky pipe. A few months later, the fog was back like it never left. I get the hesitation with the IGU swap, especially when prices are all over the place, but once it’s done, it’s just… done. No more worrying about moisture creeping in every season. Definitely agree, though—nothing about windows ever seems as simple as it should be. If you’ve got the tools and patience, tackling it yourself can actually be kind of satisfying.

Funny timing—my kitchen window did the same thing a couple years back. I tried having it resealed because, well, it sounded good on paper and cost less. But honestly, the fog crept back within the year, and I was back at square one. Ended up replacing the IGU (insulated glass unit) after all. More upfront, but it’s held up better—no more weird condensation or that “permanent cloudy day” look. I get the sticker shock, though. If it’s a window you use a lot or see all the time, I’d lean toward replacement just for peace of mind.
I get where you’re coming from with the sticker shock—had the same reaction when I priced out IGU replacements for our living room bay window a few years back. The window’s original to the house (built in the late 80s) and I figured, hey, maybe a reseal would buy me a few more years. Hired a guy who swore up and down that his process would “restore the seal integrity,” but honestly, it felt like wishful thinking. Within six months, the fog was creeping back in, and by the next winter, it looked like someone had smeared Vaseline between the panes.
In hindsight, I wish I’d skipped straight to replacing the IGU. The upfront cost stings, but it’s been solid since—no more condensation, and the room actually feels less drafty. Plus, the energy bill dropped a bit, which was a nice surprise. I do think resealing *can* work if it’s just a minor breach and you’re not too bothered by a little haze, but if you’re dealing with persistent fog or water streaks, it’s probably just delaying the inevitable.
Funny thing is, I’ve got a couple of smaller windows in the basement that I did reseal myself with some silicone as a stopgap. They’re holding up okay, but those aren’t high-traffic or high-visibility spots, so I’m not losing sleep over it. For anything you look at every day, though, I’d lean toward replacement just for your own sanity.
Anyway, you’re definitely not alone in thinking resealing sounds good on paper but doesn’t always pan out. Sometimes you just have to bite the bullet and do it right.
That’s kind of what I was afraid of… I keep looking at the price tags and thinking, “Maybe I can just caulk it and call it a day?” But knowing the fog might just come back in a few months is pretty discouraging. I’m tempted to try the cheap fix on my laundry room window, but if my living room turns into a funhouse mirror again, I might lose it. Thanks for sharing your experience—it’s weirdly reassuring to know I’m not the only one who’s tried to dodge the inevitable.
Honestly, I get where you’re coming from. It’s hard to justify dropping a bunch of cash on new glass when a tube of caulk is just sitting there for ten bucks. But here’s what I keep wondering—has anyone actually had any luck with those “defogging” services? Like, the ones that claim they can drill a hole, suck out the moisture, and reseal it? I’ve seen ads but always figured it was too good to be true.
I tried the caulk thing on my bathroom window last winter. It held up for a while, but then the fog came back even worse—almost like the sealant trapped more moisture inside somehow. Maybe that’s just my luck or maybe it’s this old house settling again. Does climate make a difference too? I’m in the Midwest with wild temperature swings, so maybe that’s part of the problem.
Anyway, is there actually a middle ground here or is it really just patchwork versus ponying up for new glass?

Yeah, I’ve been there—used caulk on a couple of my old windows and it felt like a temporary win, but that fog just sneaks back. I’ve always been skeptical about those defogging services too. Part of me wants to believe, but I wonder if it’s just a “kick the can down the road” fix. Midwest weather definitely doesn’t help... my windows seem to take a beating with all the temp changes. Sometimes it feels like it’s either live with the fog or bite the bullet for new glass, but I keep hoping someone’s found a magic middle ground.

Honestly, that’s pretty much the choice most folks end up facing. Caulk is a band-aid if the seal inside the glass unit is shot. Those “defogging” companies? I’ve seen mixed results—sometimes you get a year or two, sometimes nothing changes. Midwest swings are brutal on seals, too. If you’re handy and the sash lets you swap just the glass unit, that can save some cash versus full window replacement... but yeah, there’s no real magic fix once moisture gets in between panes.
