Funny, I tried the heat gun too and all I got was sticky goo everywhere—felt like I was making caulk soup instead of removing it. The oscillating tool definitely saved my sanity, but I still had to baby the old trim. Did you run into any issues with paint flaking off around the sash, or was that just me being unlucky with 1960s paint jobs?

Yeah, that’s pretty much my experience too. Trying to keep the trim intact is like threading a needle—one wrong move and you’re patching or replacing more than you planned. As for the paint flaking, it’s not just you. Those old 60s layers love to peel, especially if there’s any moisture trapped under the sash. I’ve found that scoring along the paint seam with a utility knife before prying helps a bit, but it’s still hit or miss.
Curious—did you try taping off the glass or just go for it? Sometimes I end up spending more time masking than actually swapping the window...
- Totally agree about the masking—sometimes feels like I spend more time taping everything off than actually working.
- Tried skipping tape once, but ended up with tiny scratches on the glass. Not worth it for me.
- Old paint is a pain. Had one spot where the entire chunk just popped off... had to patch and repaint anyway.
- I use painter’s tape now, but only on the parts that look risky, not the whole window. Saves a little time.
Masking is the real time sink, right? I always think I can just be careful and save a few minutes, but then I get those little paint flecks or, worse, the dreaded scratches. Kind of feels like a lose-lose sometimes. I like your idea of taping only the risky spots—might try that next time. Has anyone found a tape that doesn’t peel off old paint, though? That’s my main headache, especially in the corners where it’s already flaky.

Yeah, masking is always where I lose the most time. I’ve tried FrogTape and the blue 3M stuff—both work okay on newer paint, but older trim is tricky. Sometimes I’ll lightly score the edge of the tape with a utility knife before peeling it off, but that’s not foolproof either. Ever tried using painter’s paper instead of tape in those flaky spots? It’s a bit more fiddly but less risky for pulling up paint.

I’ve run into the same issue on my 1950s window trim—no matter what tape I use, the paint wants to come with it. I actually had better luck just holding a wide putty knife along the edge when painting, then wiping it clean between passes. Not perfect, but at least I’m not peeling off more paint than I started with. Painter’s paper works too, but yeah, it’s a pain to keep in place. Sometimes I think the prep takes longer than the actual painting...
I’ve definitely been there with the old paint flaking off—especially on those 60s-era sashes where the layers are like tree rings. Honestly, I’ve done the putty knife trick too, and it’s saved me more than once. One thing that helped for me: running a razor blade super lightly along the tape edge before peeling. It takes a bit more time, but it can keep that brittle paint from coming up in big chunks. Prep does eat up most of the day, but it’s worth it when you don’t have to fix up extra spots after.
That razor blade tip is spot on—makes a huge difference with those stubborn layers. I’ve definitely lost patience before and ended up with more patching than painting. It’s wild how much time goes into prep, but yeah, fixing less later is worth it. Those old sashes are like a history lesson in paint colors...
- Couldn’t agree more on the prep. I’ve tried to shortcut it before—just ends up biting me later with extra sanding or weird paint bubbles.
- Razor blade’s a lifesaver, but I’ve also used a heat gun for the really ancient stuff. Gets messy, but sometimes it’s the only way those layers budge.
- Those old sashes are wild... mine had at least five different colors hiding under there. Felt like I was peeling back time.
- One thing I learned: don’t skip taping off the glass. Thought I could “just be careful” once—nope, spent an hour scraping paint specks after.
Those old sashes are a trip, right? I swear, every time I peel one back it’s like an archeological dig—layers of paint, sometimes even oddball colors that make you wonder what was going on in the ‘70s. I’m with you on the prep, too. Folks always want to skip straight to the fun part, but if you don’t get that surface clean, flat, and dry, you’re just asking for trouble. Paint bubbles, adhesion issues, you name it.
Heat gun’s a solid move for the stubborn stuff, but I’ve had a few panes crack from getting impatient... learned that lesson the hard way. I usually stick with a carbide scraper and take my time unless I’m really up against it.
Taping off the glass is non-negotiable for me now. Tried the “steady hand” approach once—ended up cursing myself while scraping tiny flecks for ages. Blue painter’s tape is cheap insurance.
One thing I’d add: if you’re trying to save on labor during swaps, doing your own demo and cleanup can shave off a surprising chunk. Just be ready for a mess—old windows never come out cleanly.
