How Long Does It Really Take To Insulate A House?

Totally get where you’re coming from. Our 1920s bungalow has the same lath and plaster headaches - patching never quite looks original, no matter how careful you are. I wonder if it’s ever really possible to “hide” those repairs, or if it’s just something you learn to live with in an old house. Did you find the blown-in cellulose actually made a noticeable comfort difference? I’ve heard mixed things - sometimes people say it settles and leaves cold spots anyway. I keep debating whether ripping open a few walls is less painful in the long run, both for energy savings and sanity...

Honestly, I think you just get used to the quirks. I’ve tried every patching trick out there and the seams still show a bit. As for blown-in cellulose, it helped some, but yeah - settling is real. Our dining room still gets drafty in winter. Ripping open walls sounds drastic, but sometimes I wonder if it’d be less hassle than endless patch jobs...

Honestly, I get what you mean about the “quirks” - sometimes they just become part of the house’s character. Still, I’ve found that even imperfect repairs are better than staring at old damage. You mentioned,

I totally get the temptation to just keep patching - sometimes it feels like the path of least resistance, especially if you’re living in the house. But when I finally bit the bullet and opened up a couple walls to insulate, it was messy but honestly not as bad as I’d built it up in my head. Took about a weekend per room, start to finish, including cleanup and drywall. Curious - have you ever tried blown-in insulation as a middle ground? It’s less invasive than full demo but still helps with drafts.

I’ve actually looked into blown-in for my place (1920s brick, plaster walls), and I’m torn. On one hand, it does seem like a good compromise - less mess, less disruption, and you don’t have to rip out all the original lath and plaster. But I’ve read mixed things about how well it actually fills the cavities in older homes, especially if there’s old knob-and-tube wiring or random blocking inside the walls. Did you run into any weird surprises when you opened yours up?

I’m also a little paranoid about moisture issues. Some folks say blown-in can trap moisture if your exterior isn’t perfectly sealed, which is a whole other can of worms with old houses. Did you notice any difference in soundproofing or just temperature? I keep wondering if the hassle of opening up the walls is worth it for the peace of mind, even if it’s more work up front.
