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

I’ve definitely been surprised by how persistent dust can be, even with all the prep. I tried the fan-plus-filter setup during a window swap in my 1920s bungalow, and it helped, but there was still this odd draft coming from under the baseboards that sent dust everywhere. Blue tape around outlets is smart - I’ve started using painter’s plastic over whole doorways, too, but honestly, it’s almost impossible to get every last spot sealed. Has anyone ever tried those zip-up dust barriers? I keep wondering if they’re worth the extra hassle or just overkill for a standard install.

Zip-up barriers definitely do the job, but honestly, I think they’re kind of overkill unless you’re doing major demo or sanding. For a standard window install, I’ve found painter’s plastic and some decent tape gets you 90% there - especially if you’re careful with how you pull trim and handle the old windows. The zip doors are nice if you’re worried about tracking dust through the rest of the house, but they can be a pain to set up and aren’t cheap. I’d say unless you’ve got allergies or a really open floor plan, save your money.

I get where you’re coming from - those zip-up barriers look like something out of a crime scene, and the price tag kinda hurts. I did painter’s plastic for my first window swap and it mostly worked, but I still found dust in places I swear I never touched. Maybe I just have bad luck with tape? The setup time on the zip doors is annoying, but if you’re clumsy like me or have pets running around, sometimes overkill isn’t the worst thing.

I hear you on the painter’s plastic - tape just never seems to stick as well as you want, especially if there’s any humidity or dust already hanging around. I’ve seen folks double up with both painter’s tape and that blue masking tape, but honestly, it still lets some dust sneak through. Have you ever tried those magnetic dust doors? They’re a bit of a pain to set up but might be less hassle than the zipper ones if you’re worried about pets or kids. I’m curious - what’s been the worst cleanup surprise for you after a window job? For me, it’s always finding sawdust in rooms I didn’t even touch…

Funny you mention magnetic doors - I actually found them more trouble than they were worth. Maybe I just didn’t install it right, but the magnets never lined up after the first day, and my cat figured out how to sneak through anyway. What’s worked best for me is just moving as much stuff as possible out of the area and doing a deep vacuum after. I’m still finding bits of insulation in my socks weeks later, though...

I’ve wondered about those magnetic doors myself - are they really that much better than just using a regular plastic sheet and some painter’s tape? I tried the zipper kind once, but it was a hassle every time I had to go in and out, especially with arms full of stuff. Did you try repositioning the magnets at all, or was it just a lost cause from the start?

I totally get what you mean about insulation bits everywhere. When we did our living room windows, I thought I’d been super careful, but somehow there was pink fluff turning up in the weirdest places for weeks. Is there a trick to getting it all out, or is it just one of those things you have to live with for a bit? I’m curious if anyone’s found a vacuum attachment that actually helps, or if it’s just wishful thinking.

Magnetic doors are one of those things that sound great in theory, but I’ve never been fully convinced they’re worth the hassle or cost. I’ve seen them flop around if you don’t get the tension just right, and unless your opening is perfectly square (which, let’s be honest, most aren’t), there’s always a little gap somewhere. I actually tried moving the magnets around to see if it’d seal better - didn’t help much. At the end of the day, I just went back to good old plastic and tape. Not glamorous, but it gets the job done and you can patch it up on the fly.

As for the insulation bits, that’s just a universal pain. I’ve tried every vacuum attachment under the sun, even those flexible crevice tools, but nothing gets every last bit. The best luck I’ve had is doing a really thorough sweep right after the job, then another a week later when the last of it settles. Still find the odd piece months later stuck to socks or under the couch, though... Just part of the charm, I guess.

I get where you're coming from - plastic and tape are definitely more forgiving if your door frames aren’t square. I’ve had similar issues with magnetic doors, especially in older homes where nothing is quite plumb. Out of curiosity, have you tried the heavy-duty contractor plastic? I found it holds up better if you’re dealing with a longer project or rougher traffic. Also, what’s your approach for keeping dust out of HVAC vents during window installs? I’ve had mixed results taping them off, but maybe there’s a trick I’m missing.

Ha, the classic “nothing in this house is square” struggle - story of my life. I’ve used that thick contractor plastic and honestly, it’s saved me when the dog barrels through. For vents, I wedge foam scraps in before taping; seems to keep most of the dust out. Anyone else just throw an old towel over them and hope for the best, or is that just me?

Towels over vents? Been there, but honestly, they never stay put for me - always end up sucked half in or kicked off. I swear by painter’s tape and cardboard scraps. Not pretty, but it actually works, especially with all the weird angles in these old houses.
