How Long Does It Really Take To Insulate A House?

I hear you on doing both at once. I did something similar when we bought our old place - couldn’t stand the drafts any longer, so we tackled insulation and sorted out the gutters in the same stretch. It was a bit of a juggling act, but like you said, if you’re careful with vapor barriers and keep an eye on things, it’s doable. Those underground downspout kits are a game changer, though. Digging was brutal, but not having to dodge those extensions every weekend? Worth every blister.

Honestly, I’m still not convinced those underground downspouts are all upside. Had one clog up on me last spring and it was a nightmare to clear. Sometimes the old-school above-ground extensions are just simpler to maintain, even if they’re a pain to mow around.

I get where you’re coming from. Underground downspouts sound great until you have to dig one up. I’ve had to snake mine a couple times and it’s never fun. Above-ground might not look as tidy, but at least you know what you’re dealing with. Sometimes simple really is better.

Funny how we start talking insulation and end up on downspouts - happens to me all the time on job sites. I actually think there’s a parallel, though. With insulation, people get caught up in fancy spray foam or high-tech solutions, but sometimes batting in the walls and sealing the obvious gaps does 90% of the work for way less hassle. Ever tried retrofitting an old house? Sometimes you just gotta ask yourself: is this going to be a nightmare to fix later? I’d rather go simple and accessible if it means fewer headaches down the road.

That’s spot on. It’s wild how much difference you get just from basic batts and a solid air seal - especially in older houses where you’re dealing with all sorts of weird framing and hidden voids. I’ve done a few retrofits and honestly, the “nightmare to fix later” thing is real. Here’s what I’ve noticed after a few go-rounds:

- Batts are forgiving, and if you need to open up a wall down the line, you’re not dealing with a glued-in mess.
- Spray foam is great for tight spots or rim joists, but if there’s any doubt about future electrical or plumbing changes, it can be a pain. Cutting through cured foam is no joke.
- Air sealing seems to get overlooked. People focus on R-value but skip the caulk and foam around windows, doors, and top plates. That’s where a ton of heat actually escapes.
- Time-wise, insulating a typical 1500 sq ft house with batts (walls only) took me about 2-3 days with one helper. Add another day or two for careful air sealing and attic work.
- Crawlspaces are their own beast - low clearance slows everything down, and moisture issues mean you can’t just slap batts in and call it good.

I’ve always wondered if anyone’s found a really efficient workflow for retrofitting insulation in old plaster-and-lath walls? Drilling holes and blowing cellulose works, but patching after is tedious. Anyone just leave the old walls alone and focus on attic/crawlspace instead? Seems like diminishing returns if you try to do it all.
