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

HEPA vacs help but don’t expect miracles. It’s like fighting entropy…

Yeah, that’s the truth. I did all the plastic sheeting and taped every seam, but somehow I was still dusting shelves in the next room a week later. The misting helps a bit, though I always worry about getting stuff too damp and making cleanup worse. In my old place, I even tried running a box fan out the window - mixed results, but at least it felt proactive.

- Had the same issue - thought plastic sheeting would solve everything, but fine dust still found its way into random spots.
- Tried misting too, but yeah, it can make things sticky if you overdo it.
- Box fan in the window helped a little for me, especially with airflow during demo, but didn’t totally stop dust migration.
- What made the biggest difference: covering vents with painter’s tape and running my air purifier nonstop in the adjacent rooms.
- Still had to wipe down surfaces after, but at least it wasn’t a total disaster.

Dust seems to have a mind of its own...

Plastic sheeting is basically wishful thinking when it comes to fine dust. I remember the first time I did a window swap - taped up everything, even double-layered in some spots, and still had a strange layer of grit on my bookshelves across the hall. It’s like the stuff teleports. I’ve tried misting too, but if you go heavy-handed, you’re just trading dust for sticky floors and a weird smell.

Covering vents is a must, yeah. I learned that one the hard way after finding drywall dust blowing out of my bedroom vent for weeks after a project. Now I slap painter’s tape over every intake and register I can find. Air purifier helps, but mine’s not exactly industrial strength - caught some of it, but not enough to skip the post-project cleaning marathon.

Box fan in the window is decent for getting fumes and some larger particles out, but with how old my house is (1950s ranch), there are just too many little gaps for dust to sneak through. Honestly, even with all these tricks, I’ve come to accept that there’s always going to be a wipe-down phase after any big install.

One thing that helped a bit more than expected: using damp microfiber cloths instead of dry ones when cleaning up after. Picks up way more dust and doesn’t just push it around. And if you’ve got carpets nearby, lay down old sheets or drop cloths - they’ll catch more than you think.

At this point, I just factor in an extra hour or two for cleaning whenever there’s demo or install work. Dust wins every time... but at least my new windows don’t rattle in the wind anymore.

Yeah, plastic sheeting is almost pointless against that fine dust - it finds a way, every time. I’ve tried the same tricks, and still ended up with a weird film on everything in the next room. I started just moving stuff out of the way if I could, especially anything with open shelves. Have you ever tried running the HVAC on just fan mode during the work, or is that just asking for trouble? I always wonder if it helps or just spreads the mess even more.

I actually made that mistake once - thought running the fan would help suck up some of the dust, but it just blasted fine stuff into every vented room. It was like a light coating of flour everywhere, and took forever to clean. Now I just shut the system off and tape up the vents near the work area. Learned that one the hard way...

Yeah, running the fan is one of those things that sounds like a good idea until you see what actually happens. I’ve seen it turn a pretty contained mess into a whole-house disaster more than once. The fine dust from window work just gets everywhere - especially if you’re dealing with old plaster or drywall. I remember doing a job where the homeowner insisted on keeping the air moving because she thought it’d help with fumes or whatever, but by the end of the day, every room had this thin layer of grit on the furniture and floors.

Now I always recommend shutting down HVAC completely and covering up vents in any rooms near the work area. It’s a pain to tape everything off, but way less hassle than cleaning dust out of ductwork for weeks after. If you’ve got return vents nearby, those are especially important to block off. Learned that one after getting a call-back to clean out someone’s filter and blower fan... not fun.

That’s spot on about the fan - people always think moving air is the answer, but it just spreads dust everywhere. I learned the hard way with a reno in my old bungalow. Had the HVAC running, figured it’d help with ventilation, but ended up wiping down every surface for days. Blocking off returns and shutting down the system makes a huge difference, even if it feels like overkill in the moment. It’s wild how fine that dust gets... I’ve even found it inside closed cabinets after window work. Worth taking a few extra minutes to prep, for sure.

Man, you’re not kidding about that dust - window jobs seem to find every possible nook and cranny. I remember doing a job last spring where the homeowner had just reorganized her pantry, and after we finished, she found a fine layer of dust on every can, even though the doors stayed shut the whole time. I always tell folks, tape up those cabinet seams and vents if you can. It feels like overkill, but trust me, it’s less work in the end. Funny how much time you save with a little prep - learned that one the messy way.

Couldn’t agree more. I’d add - don’t forget to move electronics out or cover them. Dust finds its way inside gear, and that’s a headache nobody wants. Prepping takes 20 minutes, cleaning up after takes hours.

Totally with you on the electronics bit.

“Dust finds its way inside gear, and that’s a headache nobody wants.”

Taping up cabinets and vents does feel like overkill until you’ve spent an hour scrubbing out every nook. I’d even say it’s worth popping off vent covers if you can - easier to clean them separately than deal with a clogged HVAC later.

Some folks roll their eyes at all the prep, but honestly, it’s just common sense. You either spend a little time now or a lot more later. If you’re already moving furniture, might as well do it right. Not everything needs to be bubble-wrapped, but the more you cover, the less you regret.

I get where you’re coming from with all the prep, but honestly, sometimes I feel like taping up every cabinet and vent is just too much.

“Taping up cabinets and vents does feel like overkill until you’ve spent an hour scrubbing out every nook.”

I totally get where you’re coming from - sometimes it feels like the prep work is half the battle, and honestly, not everyone wants to go full “hazmat mode” before a project. I used to be in the “just throw some towels down and hope for the best” camp too, especially since my old place was already a bit of a dust magnet. But after doing a window install last fall, I did end up regretting not sealing up vents and cabinets. The amount of fine dust that found its way into every crevice was wild - like, I was finding it in my cereal boxes a week later.

That said, if your space isn’t ultra-pristine and you don’t mind a bit of post-project cleaning, your method works just fine for most folks. If you’ve got allergies or pets though, or if your kitchen’s right next to the work area, I’d say taping things off is worth the extra effort. Otherwise, yeah - a decent vacuum and maybe a mop afterward usually does the trick.

It’s all about what level of chaos you’re comfortable with, really…

I get wanting to keep things simple, but honestly, skipping the prep can backfire. I tried the “just vacuum after” approach once and ended up with gritty floors and dust in my closet for weeks. My advice: quick plastic over doorways, tape up vents, then towels. Five extra minutes saves hours later.

Plastic over the doorways is a game-changer, for sure. I used to think a quick sweep and vacuum was all it took - until I spent a Saturday cleaning drywall dust out of my sock drawer. Never again. The vents are sneaky too... I skipped taping them once and ended up with fine grit blowing around for days. You’re right, it’s five minutes of prep versus hours of cleanup.

I’ll admit, sometimes I get lazy and just throw towels down, but the plastic really does make a difference if you want to keep the rest of your place livable. If you’ve got pets or kids, the dust gets everywhere, fast. It might look like overkill at first, but after doing it both ways, I’m firmly on Team Over-Prep now.

I get where you’re coming from - plastic sheeting feels a bit much until you’ve seen just how far that dust can travel. I did a window replacement last fall, and I thought just closing the doors would be enough. Nope. I found dust in rooms two doors away, and my laptop keyboard was gritty for weeks. Now I’m pretty methodical about taping up vents and covering electronics, not just the obvious stuff.

One thing I’m still not sure about is how much to move out of the room entirely. For my last project, I left most of the furniture in place but wrapped it up tight with plastic. It worked okay, but some fine dust still settled underneath. Have you tried moving big items out versus just covering them? Curious if it’s worth the extra hassle, or if wrapping is usually good enough.

I’ve wrestled with the same question. For my living room, I tried just wrapping the couch and bookshelf with plastic, thinking it’d be fine. It mostly worked, but I still found a thin layer of dust under the furniture legs and in those awkward spots plastic never quite covers. The next time, I lugged the big stuff out - total pain, honestly - but cleanup was way easier. If you’ve got the energy, moving things out is worth it, especially for stuff with fabric or open shelves. But if it’s just a dresser or something solid, wrapping is usually good enough. Just takes a bit of extra vacuuming after.

Totally get the pain of lugging stuff out. I’ve done both, and honestly, I lean toward:

- Move out anything with cushions or fabric (so much less dust to clean later)
- For heavy wood pieces, I just slide a sheet under and over - good enough
-

“I still found a thin layer of dust under the furniture legs...”

It’s never perfect, but my back thanks me when I skip the heavy lifting.

I see where you’re coming from about not wanting to haul everything out - some of those old dressers weigh a ton. But I gotta ask, have you ever had a crew come in and accidentally ding up the legs or scratch the floor because the sheet didn’t stay put? I’ve seen it happen more than once, especially if there’s grit under there.

I get the logic with fabric stuff - anything that traps dust is just a pain to clean later. Still, I’d say if you’re dealing with plaster or older windows, the dust is next-level. Sometimes it gets everywhere no matter how much you prep. I’ve tried taping plastic around shelves but honestly, unless it’s really tight, fine dust sneaks in anyway. You ever try using painter’s plastic instead of sheets? It clings better and seems to keep more out.

Vacuuming after is a must, but sometimes I wonder if it’s worth just biting the bullet and moving the big stuff once, rather than cleaning around it twice. Maybe that’s just me being picky...

Yeah, moving those old dressers is basically a workout you didn’t sign up for. I’ve had my share of scratched floors - one time the sheet bunched up and the leg dragged right across the hardwood. Since then, I switched to that sticky painter’s plastic too. It’s not perfect, but it definitely keeps more dust out than regular sheets, especially with plaster dust. Still, even with all the prep, I always find a sneaky layer of dust in the weirdest places afterward. At this point, I just accept that vacuuming is inevitable... but if you can wrangle a friend to help move the big stuff once, it saves so much hassle in the long run.

I hear you on the dust - no matter how much prep you do, it finds a way. I’ve tried every combo of drop cloths and plastic, but honestly, once you start cutting into old plaster or trim for window installs, it’s like unleashing a dust bomb. The sticky plastic is decent, but I’ve seen it leave residue on floors if you’re not careful, especially if it sits for more than a day or two.

Moving the heavy stuff is a pain, but there’s a reason pros will charge extra if you leave a room packed. I always tell folks: less clutter means less chance of damage and way less cleanup later. Here’s something I’ve wondered - do you bother taping off doorways to neighboring rooms? I’ve seen people skip that step and end up with fine grit all over their kitchen counters. Is it overkill, or actually worth the hassle?
