Honestly, every insulation has trade-offs. It’s more about how you install and maintain it than the material itself, at least in my experience.
- 100% agree here. You can have the best material in the world, but if it’s installed sloppy or you skip on sealing, you’ll feel it every winter.
- I’ve seen cellulose last decades in sheds and small studios—key is keeping moisture out and patching any critter holes fast.
- Mineral wool is great for sound too, but yeah, that price tag stings lately.
- If you’re doing a guest house on a budget, dense-pack cellulose with proper prep is hard to beat for value. Just don’t skimp on the vapor barrier or you’ll regret it down the line.
- Maintenance is everything. Ignore leaks or gaps and any insulation will let you down eventually.
Honestly, you nailed it with the cellulose tip. I’ve fixed up a few backyard studios where folks tried to save a buck by skipping vapor barriers or not sealing up the base plates—always ends up costing more in the long run. If you’re handy and don’t mind a little maintenance, cellulose is a solid choice. Just curious, are you planning to DIY or hire out? That can swing your budget a lot.
I’m leaning toward DIY, but I’ll probably bring in a pro for the electrical and maybe the foundation. I don’t trust myself with that part—too much can go wrong. The rest, like insulation and sealing, I think I can handle. My budget’s tight, so I’m trying to keep labor costs down where I can, but not at the expense of stuff that could bite me later.

Hiring out for electrical and foundation work is a smart move. Those are the bits where mistakes can get really expensive, or even dangerous. I tried to run some wiring once and ended up calling in a pro anyway. Insulation and sealing are definitely manageable if you take your time and double-check the details. Stretching your budget by doing what you can yourself makes total sense, but your approach—"not at the expense of stuff that could bite me later"—is spot on. Sometimes it costs less in the long run to pay for the tricky parts.
I get where you’re coming from—foundation and electrical are two areas I won’t touch either. When I renovated my 1920s place, I thought about saving money by doing more myself, but after seeing what a mess the old knob-and-tube wiring was, I decided it wasn’t worth the risk. One wrong move and you’re not just out a few bucks, you’re looking at major repairs or worse.
Insulation and sealing, though, that’s a different story. I did all the crawlspace insulation myself last year. It’s tedious, but if you’re methodical and don’t rush, it’s pretty straightforward. Just be ready for a lot of dust and tight spaces. The only thing I’d add is to double-check local codes—sometimes even “simple” jobs have weird requirements, especially if you’re in an older neighborhood like mine.
Honestly, I’ve found that spending a bit more upfront on the tricky stuff saves a ton of headaches down the line. Cutting corners on the basics is fine, but not where safety or structure’s involved.
