Turning attics and garages into bedrooms: is it worth the hassle?

I totally get what you mean about the lingering garage smell. When we started fixing up our old detached garage, I figured a couple coats of primer and some fancy vinyl planks would do the trick. Nope - on rainy days, it’s like the ghost of every oil change past comes back to haunt us. We tried baking soda, vinegar bowls, even those charcoal bags. The only thing that really helped was running a dehumidifier nonstop, but that’s not exactly energy efficient. Haven’t tried an HRV yet, but it’s starting to sound worth it if we ever want to actually sleep in there.

Honestly, I’m not convinced an HRV will totally solve it. Sometimes those old garage smells are baked into the concrete and studs. Have you tried sealing the floor with an epoxy? That made a bigger difference for me than any air gadget.

I hear you on the HRV not being a magic fix. I’ve lived in a few older places, and sometimes it’s like the walls themselves just *remember* every decade of musty air. Epoxy on the floor does help, especially if you go all-in and do a couple coats. But honestly, in my old carriage house, the biggest game changer was dealing with the walls. I ended up using a shellac-based primer on the lower half of the studs and baseboards before drywalling, and that seemed to lock in a lot of the “old garage” aroma.

Turning these spaces into bedrooms is a wild ride, though. There’s always something unexpected - like, I once found a squirrel skeleton behind a rafter. Not exactly the cozy vibe I was going for. But if you’re willing to put in the work (and maybe live with a little quirkiness), you can get a really unique room out of it. Just don’t underestimate how much time you’ll spend chasing down weird smells or patching up ancient cracks.

If you haven’t already, check for any old insulation or vapor barriers that might be trapping odors, too. Sometimes it’s not just the concrete, but what’s been soaking into the wood and insulation over the years. I guess what I’m saying is, there’s no single fix, but layering up solutions - epoxy, primer, ventilation - gets you closer to livable.

And hey, at the end of the day, there’s something kind of cool about sleeping in a space with a bit of history... as long as it doesn’t smell like 1970s motor oil.

That’s wild - I thought I was the only one finding weird stuff in old spaces. I pulled out a handful of rusty nails and what looked like a petrified mouse nest from behind my garage drywall. Definitely not in the “dream bedroom” plans.

I’m with you on the layered approach. I tried just painting over everything at first, but the musty smell kept creeping back until I finally ripped out some old insulation. It’s kind of amazing how much odor can hide in there.

Curious - did you end up replacing all your insulation, or just spot-treating where it was worst? I’m debating if it’s worth gutting everything or just targeting the smelliest spots. The idea of sleeping somewhere with history is cool, but yeah... not if it smells like an auto shop.

Insulation is the sneakiest culprit for lingering funk, hands down. I tried to just patch the worst spots at first, but honestly, every time the weather shifted, it was like the walls were sweating out old garage smells again. Ended up biting the bullet and pulling it all - found more weird stuff than I care to admit (including what I think was a petrified sandwich?).

If you’re already tearing into it, I’d say go all in. It’s a pain, but you only want to do this once. Plus, new insulation makes a huge difference for both smell and keeping the room actually livable year-round. If you just spot-treat, you might chase odors around forever. Not to mention, you never really know what’s lurking in those untouched corners... sometimes ignorance isn’t bliss.

And yeah, nothing like “historic charm” that smells like a tire shop.

I get where you’re coming from, but I’ve actually had decent luck just spot-treating insulation in a couple flips. Not every project needs a full gut - sometimes it’s just overkill, especially if the budget’s tight. Did you try ozone or enzyme cleaners before ripping everything out? Sometimes that’s enough, unless the smell’s really baked in.

Spot-treating insulation can definitely work in some cases, especially if the odor issue is localized. I’ve had mixed results, though. Sometimes you get lucky and enzyme cleaners or ozone treatments knock out the smell, but other times - like when there’s been years of pet damage or a roof leak - the funk just won’t quit. That’s when a full gut starts to make sense, even if it feels like overkill.

I get wanting to keep costs down, especially on a flip, but I’ve found that cutting corners on the envelope can come back to bite you. Had a garage conversion where we tried to salvage some old insulation, only to have a persistent musty smell that buyers picked up on right away... ended up redoing it anyway.

Guess it comes down to how bad the problem is and how sensitive you are to risk. If it’s a faint odor and you’re not dealing with mold or major water damage, spot-treating and cleaning might be enough. But if you’re hoping for a bedroom that feels truly fresh, sometimes starting from scratch is just easier in the long run.

Definitely agree on the risk of cutting corners - buyers notice way more than we think, especially with odors. Here’s my take:

- If there’s even a hint of mold or water damage, I just budget for a full insulation replacement. Not worth risking the deal later.
- For minor pet smells, enzyme treatments sometimes work... but not always. Had one attic where we tried everything, and in the end, demoing was faster (and cheaper) than endless cleaning.
- On flips, if you’re aiming for top dollar, fresh insulation is a selling point. People walk in and instantly get that “new” feeling.

Shortcuts can save a few bucks upfront but can really tank your ROI if buyers start questioning what else got skipped. Sometimes it’s just easier to rip the band-aid off.

I’ve actually had buyers comment on that “new” feeling after we redid attic insulation - funny how something you can’t even see makes such a difference. But I’m curious, do you ever worry about losing the character of a space when you gut it? Sometimes those quirks are what people remember. I get the ROI argument, though - nothing kills a deal faster than a weird smell or water stain.

- Totally get what you mean about the “new” feeling - fresh insulation is like a secret upgrade.
- But yeah, I do worry about losing the weird old charm. My attic still has the original wood beams (creaky as heck), and people always comment on them.
- Sometimes those quirks are what make a place memorable, even if they’re not exactly practical.
- That said, I’ve also seen buyers run for the hills over a musty smell or ancient wiring... so it’s a balancing act.
- Guess it comes down to which quirks are worth saving and which ones just scare people off.

That’s exactly the dilemma I hit when I redid my garage. I kept the old sliding barn door - super impractical, but it’s the first thing guests mention. Insulation and wiring got the full upgrade, though. Some quirks just add soul, others are just... hazards.

I hear you on the quirks - sometimes they really do make the space. I’ve seen folks keep exposed rafters in attic conversions just for the character, even if it means a little extra draft in the winter. But then there’s stuff like old knob-and-tube wiring... nobody’s waxing nostalgic about that. When you’re turning a garage or attic into a bedroom, where do you draw the line between “charming” and “code violation”? Ever regret keeping a feature just for the vibe?

But then there’s stuff like old knob-and-tube wiring... nobody’s waxing nostalgic about that.

That’s exactly it - some quirks are just not worth the risk. I totally get the appeal of exposed rafters or original brick, but when I started converting my attic, I had to make some tough calls. The inspector took one look at the ancient wiring and basically said, “Nope, not happening.” I’ll admit, I tried to argue for “historic charm” but even I couldn’t keep a straight face.

I think the line is pretty clear when it comes to anything safety-related. Drafty windows? Maybe you can live with it for the look (or just pile on the blankets). But electrical, insulation, egress windows - those aren’t really optional. I did regret keeping the original floorboards for a while... they looked great, but every creak at midnight had me convinced the whole thing would collapse. Ended up reinforcing from below, so now it just sounds haunted instead of dangerous.

Guess it comes down to what you’re willing to fix later versus what could actually get someone hurt. Some “vibes” just aren’t worth the stress.

I get where you’re coming from, but honestly, I think people get a little too spooked by “old” stuff, especially wiring. Yeah, knob-and-tube isn’t ideal, but it’s not like it’s going to burst into flames just because it’s there - if it’s in good shape and not overloaded, it can be safe for a while. I’ve replaced plenty of it, but I’ve also seen newer work done worse than the old-timers did it.

I think the line is pretty clear when it comes to anything safety-related. Drafty windows? Maybe you can live with it for the look (or just pile on the blankets). But electrical, insulation, egress windows - those aren’t really optional.

Thing is, sometimes “the line” is a moving target. Insulation wasn’t even a thing in a lot of old houses, but people survived. Egress windows - sure, code says you need them, but I know folks who’ve made do with less and just use common sense. Not saying ignore safety, but sometimes the rules are more about covering liability than actual danger.

I’m all for updating what needs it, but I don’t buy into gutting everything just because it’s old. Some of the quirks are what make these conversions interesting in the first place.

I get wanting to keep the quirks - old houses have a ton of charm you just can’t fake. But I’ve crawled through enough attics and garages to know that some of those “quirks” can turn into real headaches. Had a buddy try to save on costs by leaving the old insulation and wiring in place... ended up with condensation issues and flickering lights every time the dryer ran. I’m all for not gutting stuff just because it’s old, but sometimes those codes are there for a reason, even if they feel like overkill in the moment.

I get the worry about old wiring and insulation - nobody wants to deal with a fire hazard or mold. But man, the cost of bringing everything up to code can be brutal. Do you think there’s ever a point where it’s worth taking the risk and just patching things up, or is that just asking for trouble down the line?

I totally get the temptation to just patch things up, especially when you see the price tag for a full upgrade. But honestly, with old wiring and questionable insulation, it’s like playing with fire - sometimes literally. I’ve seen people try to save money by cutting corners, only to end up paying way more after a small issue turned into a major disaster. Plus, if you’re thinking about energy efficiency or resale value, doing it right the first time pays off in the long run. It’s brutal upfront, but peace of mind is hard to put a price on.

Honestly, I hear you on the “peace of mind is hard to put a price on” part. But here’s what I keep wondering: if you’re already ripping out old wiring and redoing insulation, at what point does it make more sense to just start from scratch? Like, is there a tipping point where the hassle and cost of upgrading an attic or garage outweighs just adding an actual addition or even moving?

I’ve seen people dump a ton into converting a garage, only to realize later that the ceiling height or weird layout made it feel like a compromise. Ever run into that? Or do you think the resale value really makes up for all the headaches? Just curious where folks draw the line between “worth it” and “money pit.”

Honestly, you nailed it with this:

if you’re already ripping out old wiring and redoing insulation, at what point does it make more sense to just start from scratch?

On the other hand, if you’re in a market where square footage is gold (think Bay Area or NYC burbs), even a quirky converted space can bump up your resale. But yeah, if it starts feeling like you’re basically rebuilding half the house just to get an awkward bedroom, that’s when I’d say cut your losses. For me, if the structural stuff gets too hairy - or if the layout’s just never going to feel right - I’d rather put that cash toward an addition or save up for a move.

It really comes down to whether you’re adding value or just patching problems. If it feels like a money pit now, buyers will probably see it the same way later.

I ran into this exact dilemma a couple years back. Started turning my attic into a bedroom, thinking it’d be a quick win. Next thing I knew, I was dealing with ancient knob-and-tube wiring, zero insulation, and a floor that creaked like crazy. Like you said:

if it feels like a money pit now, buyers will probably see it the same way later.
