Getting your space ready before new windows go in - my checklist

- Taping off doorways is one of those steps that feels tedious, but I’ve regretted skipping it.

“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.

“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.

- I’ve had that same fine dust sneak into places I never expected, even after taping and covering everything. The only thing that helped a bit was running a cheap box fan in the window blowing out - kind of made a negative pressure zone so less dust drifted through the house. Not perfect, but it cut down on the worst of it.

- For taping, I’ve had mixed luck too. Blue tape sometimes pulls up old trim paint, especially if it’s humid or if the paint’s brittle. The hair dryer trick is clever - never tried pre-warming the tape but I might next time. Sometimes I just use painter’s plastic and painter’s caulk for a better seal, but that’s a pain to clean up.

- Outlets and switches are always full of surprises. I usually stuff them with a little bit of damp paper towel before taping over, then vacuum out after the mess is done. Looks weird, but it works.

- Vents: I use magnetic vent covers plus towels for double protection. Still end up finding grit months later though...

Old houses definitely keep you guessing - there’s always one more spot you missed.

You nailed it with the negative pressure trick. I swear, dust is sneakier than my dog when there’s food on the counter. I’m a big fan of painter’s plastic and caulk too - messy, but at least it doesn’t peel off 60-year-old paint like blue tape does. For outlets, I just cut a square of plastic and slap it on with low-tack tape, but your damp towel hack sounds smarter (and maybe less likely to spark a debate with the electrician). Old houses are basically dust factories with a roof, let’s be real...

Old houses are basically dust factories with a roof, let’s be real...

That’s the truth. I’ve done window installs in places where you’d swear the walls were made of flour. Painter’s plastic is my go-to too, but I’ve run into issues with caulk pulling off fragile trim. Ever tried using ZipWall poles? They’re a bit pricey, but they save me headaches on delicate surfaces. As for outlets, I usually just tape over them, but I’m curious - has anyone actually had issues with static or sparks when covering them? I’ve heard mixed things.

I’ve taped over outlets plenty of times and never had a spark or static issue, but I usually use painter’s tape, not plastic, just to be safe. The only time I got a little zap was when I used cheap electrical tape and it left residue everywhere - never again. ZipWall poles are solid, but if you’re on a budget, I’ve rigged up shower curtain rods and they do the trick for dust barriers. Just gotta watch out for old plaster crumbling if you lean anything against it... learned that the hard way.

Just gotta watch out for old plaster crumbling if you lean anything against it... learned that the hard way.

That’s the truth. My 1920s place has plaster that’s basically held together with hope and dust, so even painter’s tape can pull off chunks if I’m not careful. I’ve started using those foam outlet covers instead of taping - less mess, and I can reuse them. ZipWall’s nice, but honestly, a couple of spring clamps and an old bedsheet have gotten me through more window swaps than I care to admit.

- Agree on the plaster risk - older houses are a minefield for that.
- I’ve seen painter’s tape bring half a wall with it, so now I just use drop cloths and avoid sticking anything directly.
- If you have to mark walls, blue tape with a layer of parchment paper underneath helps, but it’s fussy.
- Bedsheet trick works, but I’ll add: plastic sheeting taped to the floor keeps cleanup easier, especially if you’re dealing with lead paint dust.
- Never underestimate how much dust gets everywhere... cover more than you think you need to.

Never underestimate how much dust gets everywhere... cover more than you think you need to.

That really hits home. I thought I was over-prepared last time, but the fine dust still found its way into the next room - no joke. I like your parchment paper tip, though I admit I usually just risk it and touch up paint after. Do you ever find plastic sheeting gets slippery, or is that just me being clumsy? Either way, your checklist sounds solid.

Plastic sheeting definitely gets slick, especially if you’re tracking dust or wearing socks. I’ve seen more than one person nearly wipe out on it. Honestly, I’m not sold on parchment paper - seems like it’d tear too easily, especially if you’re moving ladders or tools around. I usually go with heavy drop cloths for the main walkways, then tape up doorways with zip walls. Does anyone actually get away without a little paint touch-up, though? I haven’t yet…

- Heavy canvas drop cloths are my go-to, too - less slipping, and they hold up when you’re dragging stuff around.
- For dust, I’ll sometimes use a sticky mat at the entry point. Catches a lot more than I expected.
- Zip walls are great, though I’ve had tape peel paint before - blue painter’s tape seems safest.
- I’ve never gotten through a window swap without at least some touch-up, especially if the trim’s old or the walls aren’t perfectly square.

Has anyone tried those self-adhesive floor films? Wondering if they’re any less slick than plastic sheeting...

I’ve used those self-adhesive floor films a couple times - honestly, I’m not convinced they’re much less slick than regular plastic sheeting. They do stick better, so they don’t bunch up as easily, but if you’ve got dust or grit underfoot, it can still get slippery. Plus, peeling them up sometimes leaves a sticky residue, especially if it’s been down for more than a day or two. I keep going back to canvas for most jobs, even though it’s bulkier to haul around.
