Pulled out a 90s window last summer and found a handful of old nails, a plastic army man, and a ton of dust. Not much insulation either—just a thin strip of yellowed fiberglass. If you’re replacing, I’d say: 1) check for rot, 2) add real insulation, 3) don’t trust whatever flashing you find. Always seems like a surprise in there...
Always seems like a surprise in there...
Totally agree with this. When I pulled out the windows in our 80s split-level, I actually found a petrified mouse nest wedged behind the frame. Made me wonder—how much stuff ends up in these wall cavities over the years? I’m curious, did you notice any water staining or signs of leaks? I found some old flashing that looked fine at first but was hiding a soft spot underneath. Makes me think, how many people just slap in new windows and never check for hidden issues?
Funny you mention the mouse nest—I found a pile of old insulation and what looked like a bird feather stuck in one corner when I swapped out the windows in our ‘76 ranch. Didn’t spot any water stains, but there was a weird draft coming through where the caulk had totally failed. Ever wonder if the drafts are from shoddy installs or just age? Sometimes I think these surprises are more about what you *don’t* see than what you do. Anybody else run into odd smells coming from the walls after opening things up?

I’ve gone back and forth on this. My place is late ‘80s and some of the window frames looked like they were barely attached—caulk was basically dust. But then again, who knows what 30 years of weather does to cheap vinyl? When I opened up one wall, there was a faint musty smell, almost like wet cardboard, but no signs of water. Has anyone found stuff that looked fine but smelled off? Makes me wonder what’s hiding between the studs.
I get where you're coming from, but I’m not totally convinced it’s just age. When I pulled my old windows (mid-90s build), the caulk was dust too, but the insulation was barely there—like a couple tufts of fiberglass stuffed in sloppy. I think sometimes the original install was just rushed or cheap, and age just makes it worse. That musty smell without water stains is weird though... I’ve had that too, and always wonder if it’s old drywall or just humidity trapped over the years.
- Can’t argue with you there—mid-90s vinyl windows were hit or miss, and a lot of builders just did the bare minimum.
- Seen that “dust caulk” plenty... but yeah, sometimes it’s just shoddy work from day one, not just age.
- The musty smell without stains is a tough one. In my experience, old drywall can hang onto odors for decades, especially if airflow’s bad.
- Don’t beat yourself up—sometimes it’s impossible to tell what corners got cut until you demo. At least now you know what you’re dealing with!
- Totally get where you're coming from. Pulled out a few windows in my old place and found insulation that was basically just wadded up newspaper... Not sure if it was age or just someone cutting corners.
- That musty smell is the worst. Sometimes it's just trapped air and old materials, not necessarily mold or leaks.
- At least now you can do it right—feels good knowing what's really behind those walls, even if it's a headache at first.
- Finding newspaper as insulation is more common than you'd think—seen it in plenty of houses from the 60s and 70s.
- That musty smell usually comes from old wood or trapped moisture, not always a sign of a bigger issue, but worth checking for rot just in case.
- Tearing stuff out is a pain but at least you know what you’re working with now. Always better to fix it right the first time, even if it’s a hassle up front.
- Honestly, some of the shortcuts people took back then are wild... makes you appreciate modern codes.

Yeah, I ran into that too. Pulled out a wad of old classifieds stuffed behind my windows—kinda wild what passed for “insulation.” I agree, fixing it right now is a hassle, but at least you know what’s in your walls. Makes me wonder what else is hiding in there...
When I swapped out the old windows in my place, I found a bunch of crumpled magazines jammed in the gaps. Not even newspapers—just random issues from the late 70s. I get that people used what they had, but it’s kind of sketchy how little insulation there actually was. Makes me second-guess what shortcuts might be hiding elsewhere in the house... Guess you never really know until you start tearing things apart.
