How worried should I be about lead paint when swapping out old windows?

Honestly, I get the urge to go “full containment” with plastic and HEPA, but sometimes it’s just not practical, especially if you’re working alone or in a tight space.

“don’t trust swabs much either”

I get where you’re coming from with the urge to go all-in on containment, but in practice, it’s not always feasible - especially when you’re squeezing around old radiators or weird trim. I’ve done a few window swaps in pre-1950s houses, and honestly, the wet methods you mentioned have saved me more than once. I’ve tried the swabs too, but sometimes they just give you a false sense of security. Had one come up negative, then a lab test showed dust levels way over the limit.

I’ve found that taping off the immediate work area and using a garden sprayer (set to a fine mist) keeps things manageable. I still use a HEPA vac, but only after everything’s dampened down. Do you ever worry about tracking dust out on your clothes or tools? I started keeping a dedicated pair of coveralls and a “dirty” bin for tools - probably overkill, but it helps my peace of mind.

Curious if anyone’s had luck with those sticky mats by the door? I’ve thought about trying them but not sure if they’re worth it in a home setting...

Sticky mats are hit or miss for me - used them on a bigger job, but in a tight home space they didn’t stick well to old wood floors. I’m with you on the coveralls and tool bin. I also keep a box of disposable shoe covers by the door, just in case I need to step out mid-project. Ever tried taping plastic sheeting down as a walk-off area? That’s been more reliable for me than the mats, especially if you’re tracking in and out a lot.

Yeah, I’m with you - sticky mats just end up crumpled on my floor like a sad tortilla. Taped plastic sheeting plus a layer of old towels works way better for my sanity (and socks). If you’re worried about lead dust, I’d add: mist everything with water before cleanup. It keeps dust from floating around and makes vacuuming less of a nightmare.

That’s exactly what happens at my place. I tried those “professional” sticky mats once and they lasted about two hours before turning into a trip hazard. I’ve had better luck with the plastic sheeting too, but I’ll admit, I get lazy and sometimes just use cardboard and painter’s tape. Not the gold standard, but it beats tracking dust everywhere. Anyone else ever try using a shop vac with a HEPA filter? I swear by mine, even if it sounds like a jet engine.

Honestly, cardboard and tape work better than a lot of those sticky mats in my experience - at least they stay put. When it comes to lead paint, I always recommend going the extra mile with plastic sheeting and taping off vents. HEPA shop vacs are a must, but just be careful - some regular shop vacs labeled “HEPA” aren’t fully sealed and can still blow dust around. Keep everything damp when you’re working; dry scraping is where the real mess happens. It’s a pain, but worth it for peace of mind.

Funny how much “HEPA” gets thrown around these days - makes you wonder if anyone actually checks what’s inside those vacs. I’ve seen so-called “sealed” shop vacs that puff out just as much dust as the regular ones. Can’t say I fully trust a label anymore.

When I swapped out the windows in our ‘52 ranch, I tried doing the whole plastic sheeting and taped vents routine. It definitely helped, but honestly, there was still a fine layer of dust everywhere after. Maybe I’m just paranoid, but I feel like no matter what you do, some of it escapes. Is it overkill to worry about a little dust if you’re not sanding or scraping? Or is that just wishful thinking?

I’ve used cardboard too when I’m feeling lazy - it’s better than nothing, but the dog always manages to find a corner to chew on and then it’s chaos. Can’t win.

Are we all just spinning our wheels trying to be perfect with this stuff, or is there a real risk unless you’re doing major demolition?

I hear you on the “HEPA” label - sometimes I think it’s just a sticker they slap on to charge more. I’m a bit of a gadget nerd, so I actually cracked open my vac once and… yeah, not exactly NASA-level filtration inside. As for dust, even with all the plastic and tape, I always find some sneaks out. Maybe it’s just part of working on old houses? That said, I do get a little more careful if I know there’s lead paint involved - I figure it’s not worth rolling the dice, especially with pets or kids around. But if you’re just prying out old windows and not grinding or sanding, it seems like the risk is lower. Anyone else feel like we’re overthinking it sometimes, or is that just me?

That’s been my experience too - no matter how much I prep, there’s always a bit of dust that gets away. I wouldn’t say you’re overthinking it, though. With lead, I figure it’s better to err on the side of caution, especially if there are kids or pets in the house. When I did my own window swap, I stuck to gentle prying and avoided power tools. The risk is definitely lower if you’re not sanding or scraping, but a little extra care never hurts. Old houses have their quirks, but you’re handling it the right way.

I totally get what you mean about dust sneaking out, even with all the prep. Here’s what I did: first, I misted everything down with water before starting - supposed to keep dust from floating around. Then, I used a cheap box fan in the window blowing out, just to help pull any stray dust outside. Afterward, I wiped everything with damp rags instead of dry sweeping. It’s not perfect, but it seemed to help. Old houses just have their own rules, don’t they?
