- Taping off doorways is one of those steps that feels tedious, but I’ve regretted skipping it.
That’s been me—had to wipe down every surface in the next room because I thought a closed door would be enough.“I’ve seen people skip that step and end up with fine grit all over their kitchen counters.”
- Sticky plastic is a double-edged sword. It works, but yeah, I’ve had to scrape up the residue after a few days. Not fun.
- I’m curious—has anyone tried those negative air machines or just a box fan with a filter in the doorway? Wondering if it’s overkill for a regular window job or actually makes a difference.
I’ll admit, I’m one of those people who usually tries to get away with just shutting the door and crossing my fingers. Last time I had windows replaced, though, the dust found its way through every crack and crevice—ended up vacuuming my couch cushions for days. Taping definitely feels like a pain, but I guess it’s less of a pain than cleaning up drywall grit from your cereal bowls.
About the sticky plastic—I actually switched to painter’s drop cloths and just tape them at the edges. No residue, and you can toss them in the wash or reuse them for other projects. It’s not as airtight, but it’s been “good enough” for me.
As for fans and filters, I’ve only tried the box fan trick once (just a cheap filter taped on). It kept some of the dust down, but honestly, for a single window job it felt like more setup than payoff. Maybe if you’re doing a whole row of windows or working in an older house with crumbly plaster... otherwise? Not sure it’s worth hauling out extra gear.
Right there with you on the dust—last time I skipped taping, I found grit in my toaster for a week. I’m all for shortcuts, but a little prep saves way more hassle later. Drop cloths are a solid move; I’ve used old bedsheets in a pinch, though they’re not exactly airtight either. The fan-and-filter trick feels like overkill for one window, but I’ll admit, if you’re dealing with ancient plaster or a whole bunch of windows, it’s worth thinking about. More work up front, but maybe less sneezing later...
I always wonder if the dust is just part of the deal with window installs, no matter how much you prep. I’ve tried both plastic sheeting and bedsheets, and honestly, the plastic’s better for keeping the fine stuff out, but it’s such a pain to tape up around weird trim. Anyone else find that painter’s tape just doesn’t stick to old plaster walls? Drives me nuts.
As for the fan-and-filter thing, I get where you’re coming from—it can feel like overkill if it’s just a single window. But I tried it during a bigger job once (three windows in one room, 1920s house with crumbly horsehair plaster), and my allergies were way less miserable than usual. Still, sometimes I just want to get it done and not fuss with extra steps. Is there a middle ground? Like, maybe just doing the fan trick until the messy part’s over, then ditching it? Or is that just wishful thinking...
- Dust is basically inevitable, especially with old plaster—no matter how much I try to seal things off, some always sneaks through. Plastic sheeting definitely works better than fabric, but yeah, it’s a wrestling match with weird trim and corners. I’ve had painter’s tape peel right off my 1940s walls after about ten minutes. Sometimes I double up with masking tape underneath, which helps a little.
- For the fan-and-filter thing, I’m with you—it feels like overkill for one window. When I did my living room (two windows), I ran a box fan in the window for just the demo part. Once the messiest stuff was done, I turned it off and just kept the door closed. It didn’t catch everything, but it made cleanup way easier.
- If you want a middle ground:
• Fan in the window during demo only.
• Quick plastic drop cloth on the floor (skip taping every edge).
• Old towels under doors to keep dust from drifting.
- Honestly, unless you’re super sensitive to dust or have expensive electronics nearby, I’d say don’t stress too much about perfection. You’ll be vacuuming anyway... might as well save your energy for that part.
I hear you on the painter’s tape—mine barely stuck to the old horsehair plaster, especially near the windows. What’s worked for me is blue tape over a thin strip of masking tape, but even then, it’s hit or miss. I usually just resign myself to a deep vacuuming after. The fan trick helps, but I’ve also found that if you wet-mop right after demo, it grabs way more dust than dry sweeping. Not perfect, but good enough unless you’re dealing with allergies or a home office full of tech.
That’s interesting about the double-layer tape—never tried that, but now I’m curious if it’d help with my crumbly plaster. I’ve had painter’s tape peel off chunks of paint before, which is just insult to injury when you’re already prepping for a messy job. Have you ever used that green FrogTape stuff? I heard it sticks better on rough surfaces, but I haven’t tested it myself.
I totally get the deep vacuuming routine. I swear, no matter how careful I am, there’s always a fine layer of dust that shows up days later... Maybe it’s just old houses being leaky? Wet-mopping does seem to grab more, but sometimes I worry about getting the floors too damp near the baseboards.
Do you do anything special to protect outlets or vents? I’ve started taping plastic over mine after finding sawdust in my HVAC returns. Not sure if it’s overkill or not, but it made me feel a little less paranoid about dust getting everywhere.
I’ve used FrogTape a couple times—honestly, it’s way less likely to rip up old paint than blue painter’s tape, but it can still pull a little if the wall’s flaky.
Not overkill at all. I do the same thing, plus I stuff a little towel in the vent before the plastic, just to be safe. The dust finds its way in no matter what, but every little bit helps. And yeah, those old houses just seem to breathe dust... part of their charm, I guess?“I’ve started taping plastic over mine after finding sawdust in my HVAC returns.”
- Definitely agree on the dust thing—old houses just have a way of hiding dirt until you start any kind of project.
- When I had my windows swapped out last spring (1928 bungalow), I tried a bunch of stuff to keep things tidy:
- Used FrogTape, but yeah, even that can lift paint if your walls are already peeling. I started testing a tiny patch behind a curtain first, just in case.
- Covered all the vents with plastic AND a layer of cheap microfiber towels. The towels actually caught more dust than I expected—seems like overkill but my allergies were grateful.
- Rolled up area rugs and stashed them in the garage. Picked up this trick after my first reno when I spent days vacuuming grit out of the living room rug.
- Tacked up old sheets over doorways. Not perfect, but it stopped most of the bigger debris from drifting into other rooms.
- One thing I always forget: outlets and light switches. After my last project, I found sawdust inside a couple outlets—had to vacuum them out with that tiny brush attachment. Next time, I’m taping them up too.
- I’ve tried both blue tape and FrogTape, and honestly, if your paint is old or there’s humidity in the air, neither is foolproof. Sometimes the tape just won’t stick, or it peels off in chunks. I keep a small putty knife handy to press it down better, but results are mixed.
- As for charm... yeah, I love my old house, but sometimes it feels like it’s actively trying to sabotage any cleaning efforts. Dust gets in places you didn’t even know existed.
Not sure there’s a perfect prep checklist, but every little step helps. I’d rather spend an extra hour taping and covering than weeks cleaning up later.
That list is spot on—old houses really are their own ecosystem when it comes to dust and debris. I remember swapping windows in my 1915 foursquare, thinking I’d done a thorough job taping and covering, only to find fine plaster grit in my kitchen drawers weeks later. Covering vents with towels is a trick I wish I’d known sooner... I just used painter’s plastic, but it never seemed to catch the really fine stuff.
You nailed it about the tape, too. Sometimes it feels like no matter which brand you use, old paint just wants to come off with it. I’ve had better luck with the green FrogTape if I run a hair dryer over it first, but it’s hit or miss—humidity makes everything ten times harder.
Outlets and switches are the sneaky ones. Last time, I caught myself vacuuming out a light switch box with a straw taped to the hose—looked ridiculous, but it worked. Honestly, the prep always feels endless, but like you said, it’s way better than weeks of cleanup. Old houses keep us humble, that’s for sure.
