Insulating takes longer if you’re gagging every five minutes, trust me...
That’s the truth. I had a crawlspace job last year where the insulation was so musty I had to take breaks every half hour just to breathe fresh air. It’s wild how much the smell can slow you down.
On timing, I’ve found it really depends on the house size and what you’re dealing with. For a 1,500 sq ft attic, if you’re just laying batts and there’s no weird cleanup, maybe a full day with two people. But if you’re pulling out old, gross insulation and dealing with rodent nests or mold, it can stretch into two or three days easy. Did you run into any surprises under your insulation? I once found a whole stash of ancient beer cans—guess the previous owners liked to party in the rafters.
Curious if anyone’s tried those odor-sealing sprays before putting new insulation in? I’ve only used baking soda and fans, but sometimes it feels like the funk never fully leaves...
Beer cans in the attic—now that’s a renovation time capsule. I’ve tried those odor-blocking sprays a couple times, but honestly, if the funk is deep enough, it’s like spraying perfume on a gym sock. Sometimes you just have to rip out everything and hope for the best. I swear, nothing clings to your clothes like old insulation dust and mystery smells...
- Totally agree—old insulation dust is like glitter, it never leaves.
- Tried every “eco” spray under the sun, but if the attic’s got that deep funk, you’re just marinating in it.
- I’ve found pulling out the old stuff is the only way to go, even if you end up looking like a chimney sweep.
- Ever tried using recycled denim insulation? It’s less itchy, but man, it still picks up weird smells if there’s any leftover funk in the wood.
- Curious—anyone ever actually managed to save old insulation, or is it always a lost cause?

That’s the truth. I tried to salvage some old fiberglass once—thought I’d save a few bucks—but honestly, it just wasn’t worth it. Even after vacuuming and airing things out, the smell and dust stuck around. If you’re on a budget, I’d say step one is to bite the bullet and remove the old stuff (full coveralls and mask are a must). Step two: check for any leaks or moisture before putting in anything new, otherwise you’re just trapping more funk. Denim’s nice for less itch, but yeah, it doesn’t fix a musty attic. Sometimes starting fresh is just cheaper in the long run.
Takes me back to the time I thought I could just “patch up” the insulation in my crawlspace. Ended up looking like a powdered donut and still found fiberglass in my socks a week later. Honestly, if you’re doing a whole house, plan for at least a couple days—more if you’re pulling out old stuff. Rushing it just means you’ll be itchy and grumpy for nothing.
