Anyone actually had luck with those “defogging” companies? I’m skeptical, but maybe I’m missing something.
I’ve seen a few jobs where people tried the defogging route. Honestly, it’s hit or miss. The process is basically drilling a small hole in the glass unit, flushing it out, and then sealing it up again. Sometimes it buys you a year or two if the seal failure isn’t too bad, but in most cases, the fog comes back eventually. The main issue is that once the seal’s gone, moisture will keep finding its way in.
Swapping just the glass unit (the IGU) is usually the way to go if your frames are solid. It’s less invasive, keeps the existing look, and you’re not paying for new trim or dealing with siding touchups. I’ve replaced quite a few IGUs for folks who thought they’d need full windows—most are surprised how quick it is. Usually in and out in under an hour per window, depending on the setup.
Full replacement only makes sense if your frames are shot or you want to change the style or function (like going from sliders to casements). Otherwise, you’re just spending extra for no real gain.
One thing to watch for: sometimes older frames can be tricky if they’re warped or out of square. Makes getting a perfect fit tougher, but not impossible.
Long story short, defogging is more of a band-aid. If you want a real fix and the frames are good, just replace the glass units. Costs more upfront than defogging but saves hassle down the line.
Had a similar situation a couple years back with the windows in our sunroom. I tried one of those defogging kits after watching a YouTube video—figured it was worth a shot before shelling out for new glass. It looked better for maybe six months, then the haze crept right back in. Like you said, once that seal’s toast, it’s just fighting a losing battle.
Ended up ordering new IGUs and swapping them out myself since the frames were still in decent shape. Not gonna lie, it was a little nerve-wracking popping out the old glass the first time, but after the first window it went pretty smooth. Saved a bunch compared to full replacement, and the room actually stays warmer now.
Only downside was tracking down the right size units—our house is from the 80s and some of the windows weren’t exactly standard. Still, way happier with that route than the temporary fix. Defogging might buy you some time if you’re in a pinch, but for me, it just delayed the inevitable.
That’s pretty much what I was afraid of with those defogging kits—seems like a band-aid at best. I keep looking at the cloudy corner of my living room window and thinking, “maybe I can just reseal it?” but deep down I know it’s probably toast. Never thought I’d be googling IGUs at midnight, but here we are... Glad to hear swapping out just the glass worked for you, even if tracking down the right size was a pain. Guess I’ll have to add “measuring windows” to my list of weird adult hobbies.
I’ve tried the reseal route before—honestly, it was more hassle than it was worth. The seal failed again after a year and I ended up right back where I started, but with less patience. Swapping out just the glass isn’t glamorous, but at least it fixes the root problem. Measuring windows is a weird rite of passage... I swear my tape measure disappears every time I need it. If you go for new glass, double-check your measurements, trust me.

I get where you’re coming from, but I’ve actually had the opposite experience with resealing. Maybe it depends on the window or the climate? I live in a pretty mild area (not a ton of freeze/thaw cycles), and I managed to reseal a couple of my old double-pane windows about five years ago. I used one of those window repair kits from the hardware store—definitely not fancy, and it took some patience, but the seals are still holding up. I figure if you’re not ready to shell out for new glass, it’s not a terrible stopgap.
That said, I totally agree about measuring being a pain. I swear, every time I pull out the tape, I end up re-checking three times because I don’t trust myself. And the glass shops always want measurements down to the sixteenth of an inch, which just feels like a setup for anxiety.
Swapping out the glass is definitely the “clean slate” approach, though. I did that in my daughter’s room last year after the fogging got so bad she couldn’t see the bird feeder. It was pricier than I expected, but at least it’s done and I don’t have to think about it for a while.
I guess for me, resealing makes sense if the window’s not in a high-traffic area or getting blasted by weather. But if you’re dealing with a spot that’s constantly foggy or leaking, I can see why you’d want to just rip the bandaid off and do new glass.
Funny thing—my neighbor tried both methods and ended up just replacing the whole window. Said he was tired of “nickel and diming” it. Sometimes I wonder if that’s the way to go, but I’m too stubborn (and cheap) to give in yet.
- I totally get the measuring anxiety—those tiny fractions stress me out too.
- Tried resealing one window, but it didn’t last through a wet winter. Maybe our climate’s just too rough?
- Replacing the glass felt expensive upfront, but honestly, not having to mess with it again is pretty nice.
- Curious if anyone’s had luck with those defogging services? I keep seeing ads but not sure if they’re legit or just a temporary fix...
Tried resealing a couple of my windows a few years back—used one of those DIY kits with the silicone and everything. Looked good for maybe six months, then the fog crept back in, especially after a few storms. Our winters are pretty damp, so I’m starting to wonder if some climates just chew through those seals faster than others.
Replacing the glass was a tough pill to swallow price-wise, but honestly, it’s been set-and-forget since then. No more condensation between the panes, and I stopped stressing every time it rained. Still, that initial bill stings.
About those defogging services… I had a guy quote me once, but he admitted up front it’s mostly a cosmetic fix—he drills a tiny hole, sucks out the moisture, and plugs it. Supposedly it helps for a bit, but if your seals are shot, moisture just sneaks back in eventually. Anyone actually had better luck with those? I’m skeptical, but maybe I just got a bad pitch.

That matches what I’ve seen. The defogging drill-and-plug method doesn’t address the root problem—the failed seal. Maybe you get a clearer view for a few months, but in damp climates like yours (and mine), the moisture just finds its way back. Tried it on a rental I managed—looked better for one season, then right back to foggy.
Resealing with silicone is more of a stopgap too, especially if the window unit’s already compromised. Once that desiccant inside the IGU (insulated glass unit) is saturated, there’s not much you can do short of swapping out the glass. Expensive upfront, but like you said—set and forget.
If the window frames are still solid and you can just replace the glass unit instead of the whole window, that’s usually the best long-term fix. Pricey, yeah, but worth it for peace of mind—not having to mess with it every winter.

Nailed it. Folks try to stretch the life with silicone or those defogging tricks, but honestly, I haven’t seen one last more than a season or two. If the frames are still in good shape, just replacing the IGU makes way more sense long-term. I get that it’s a chunk of change upfront, but you’re not battling fog every year, and your energy bills might even drop a bit. Had a client in a lakeside place—after we swapped the glass, no more calls about fog or drafts. Worth it for the peace of mind.
I always wonder if those defogging kits are just a band-aid. Tried one on a rental a couple years back—looked okay for a few months, then the fog crept right back in. Ended up swapping the IGU anyway. Not cheap, but honestly, the room felt warmer after, and the drafts stopped. Still curious if anyone’s had luck with resealing long-term, but I haven’t seen it work yet.
