my battle with moldy closets and frizzy hair

Swapping out louvered doors for solid ones with a vent is a move I wish I’d thought of sooner - those slats are basically dust magnets, right? Did you notice any difference in the smell situation after insulating? I always worry about trapping musty odors in, but maybe that’s just me being paranoid. Also, did you seal up the foam board edges or just wedge them in? I tried the “good enough” method once and ended up with a squirrel-sized draft.

Funny you mention the “good enough” method - I once tried just wedging foam board in my laundry closet and ended up with a weird whistling noise every time the dryer ran. I did notice the musty smell faded a bit after sealing the edges with foil tape, though. Did you ever try running a small fan or dehumidifier in there? Sometimes it’s less about insulation and more about air flow, at least in my experience.

Did you ever try running a small fan or dehumidifier in there? Sometimes it’s less about insulation and more about air flow, at least in my experience.

I went down the dehumidifier route after trying (and failing) with just sealing gaps. Here’s what worked for me, step by step:

1. Pulled everything out of the closet - seriously, even the random socks that fall behind the dryer.
2. Cleaned all surfaces with a vinegar solution to kill any lingering mold.
3. Set up a small, plug-in dehumidifier in the corner. I got one of those compact ones that fits on a shelf.
4. Left the door cracked open whenever possible, especially after running the dryer.
5. Checked and emptied the dehumidifier tray every couple days.

I noticed a big difference in both the smell and how my clothes felt - less damp, less frizzy hair after laundry day too. Insulation helped a bit, but honestly, airflow made more of an impact than anything else. The whistling noise thing is real though... I had to reposition my foam board after it started making weird sounds every time the washer spun up. Sometimes “good enough” turns into “good enough for now,” right?

Funny, I had almost the same experience with airflow making a bigger difference than insulation. I tried weatherstripping and even some fancy closet liners, but nothing beat just cracking the door and letting a fan run for a bit. The dehumidifier definitely helped with that musty smell too. Did you ever try one of those moisture absorber tubs? I tossed a couple in the corners and they seemed to help, but maybe that was just wishful thinking... Also, curious if you noticed any difference in your energy bill after running the dehumidifier more often?

Yeah, airflow really is the unsung hero in these situations. I used to obsess over insulation and fancy liners too, but honestly, just propping the door open and letting a fan do its thing made the biggest difference for me.

- Tried those moisture absorber tubs - mixed results. They seemed to help a bit with dampness, but I wouldn’t call them a game changer. Maybe more of a psychological boost than anything else.
- Dehumidifier definitely helped with the musty smell, but yeah, it did nudge my energy bill up a little. Not crazy high, but noticeable if you’re running it 24/7. I started using it on a timer or just during the most humid parts of the day to balance things out.

You’re not imagining things - sometimes simple fixes like airflow and targeted dehumidifying work better than all the “miracle” products out there. It’s kind of satisfying when something low-tech actually does the trick.

I’ve been down this road with closets that just refuse to stay dry, and I agree - airflow is underrated. I used to think those moisture absorber tubs were the answer too, but honestly, they’re more of a band-aid than a solution. They fill up fast and don’t really tackle the root cause if you’ve got persistent humidity.

Dehumidifiers are great, but yeah, they can be a bit of an energy hog if you’re not careful. I ended up getting one with a built-in humidistat so it only kicks on when the humidity creeps above a certain level. That helped keep the bills in check without sacrificing results. If you haven’t tried that kind yet, it might be worth looking into.

One thing I’d add - if your closet backs up against an exterior wall or is in a corner of the house that doesn’t get much sun, you might want to check for any small leaks or cracks letting in moisture from outside. I found a tiny gap near the baseboard in mine that was letting damp air seep in every time it rained. Sealing that up made a bigger difference than any product I bought.

As for frizzy hair...I feel your pain there too. Humidity just wrecks my mornings sometimes. A friend swears by keeping a little bowl of baking soda or rice in her closet to absorb extra moisture (kind of like those silica gel packets), but I haven’t noticed much improvement myself.

At the end of the day, nothing beats just letting air move through and not overstuffing the closet. It’s not glamorous advice, but it works better than most “miracle” fixes out there. Sometimes low-tech really is best - even if it means living with your closet door open half the time and explaining to guests why your fan is pointed at your shoes...

You’re spot on about airflow - people underestimate how much just cracking the door or running a fan can help. I’ve seen a lot of folks throw money at fancy gadgets, but unless you address the source (like you did with that baseboard gap), it’s just treating symptoms. I’d add: sometimes closet shelving can block air movement too, especially those solid wood ones. Swapping for wire racks made a difference in a couple rentals I’ve managed. Not glamorous, but it works. And yeah, the frizzy hair struggle is real... humidity finds a way.

Wire racks really do make a difference - funny how something so basic can help more than those pricey dehumidifiers sometimes. I once tried one of those closet air purifiers, but honestly, just leaving the door cracked did more. Have you ever tried those moisture absorber tubs? I’m never sure if they’re actually helping or just collecting dust. Also, does anyone else notice their shoes get musty way faster in summer?

I actually think the dehumidifiers do more than people give them credit for, especially in older homes where airflow’s a pain. Those moisture absorber tubs help a little, but they fill up fast and honestly, I always forget to empty them. For shoes, have you tried cedar inserts? They seem to slow the mustiness for me, though nothing’s perfect when humidity spikes.

You’re right about dehumidifiers - they’re underrated, especially in drafty old houses where you can’t count on good airflow. I’ve found the tubs are more hassle than help, honestly. Cedar inserts are a solid call for shoes, though I’ve had mixed luck with them when it’s really muggy. If you ever get tired of emptying tubs, maybe look into a small energy-efficient dehumidifier for the closet itself? It made a bigger difference than I expected. Mold’s stubborn, but every little bit helps.

I hear you on the tubs - they’re just another thing to forget about until you step in a puddle. I tried a rechargeable mini dehumidifier in my closet last summer, and it was a game changer. Less fuss, and my sweaters stopped smelling like an old basement. Mold’s sneaky, but a little tech goes a long way.

That’s interesting - did you find it made a dent in your electric bill, or was it pretty efficient? I’ve always stuck with the cheap tubs, but honestly, they’re more hassle than they’re worth. Ever try just leaving the closet door open for airflow, or is that not enough? I’m always looking for low-cost fixes that don’t add to the clutter.

Leaving the closet door open does help a bit, but in my experience, it doesn’t really tackle the root of the problem - especially during those humid spells. I tried the tubs too, but they just seemed to fill up so fast and then I’d forget about them until it was too late... The rechargeable dehumidifiers are surprisingly efficient, though. I didn’t notice any spike in my bill, and it’s less messy than swapping out tubs all the time. If you’re worried about clutter, maybe try hanging one up or tucking it on a shelf? It’s pretty low-profile.

Rechargeable dehumidifiers are a game changer, honestly. I’ve put them in multiple units and they’re way less hassle than the disposable tubs. You’re right about the closet door - airflow helps, but if you’ve got real moisture issues, it’s just a band-aid. If you want to go all-in, you might even look at adding a small vent or fan. It’s more upfront work, but it pays off long-term with less mold and fewer headaches.

Title: Moldy Closets and Frizzy Hair - Ventilation Actually Matters

- Seen a lot of folks try to solve closet moisture with just dehumidifiers or those disposable tubs. They help, but in my experience, they’re only half the battle.
- Had a client last year with a walk-in closet that kept getting that musty smell, no matter what she tried. She was using rechargeable dehumidifiers, cracked the door, even ran a fan outside the closet. Still had mold creeping up behind her shoe rack.
- We ended up cutting in a small passive vent near the top of the closet wall (just a 4” louvered grille into the hallway). It wasn’t fancy, but it let warm air circulate out. Paired that with a low-profile exhaust fan on a timer - runs for 20 minutes twice a day.
- After that, zero mold issues for over a year now. She said her clothes even felt less “damp” and her hair wasn’t frizzing up as much after getting dressed.
- Honestly, airflow is underrated. Dehumidifiers are great for maintenance, but if you’re dealing with persistent moisture (especially in older homes or basements), you need to give that air somewhere to go.
- One thing I’d watch out for: if you’re adding vents or fans, make sure you’re not just moving moisture into another problem spot (like an attic or crawlspace). Always check where that air’s going.
- Not everyone wants to cut holes in their walls, but sometimes it’s the only way to really fix the root cause. Otherwise, you’re just chasing symptoms.

Funny enough, I’ve seen people blame their shampoo or laundry soap for frizzy hair when it’s really just humidity trapped in their closets... Go figure.

- Cutting in a vent is honestly the move, even if it feels drastic at first. I’ve seen people try every “no-damage” trick in the book and still end up with ruined shoes and that weird closet funk.
- I’m always curious - did you notice any impact on your energy bills with the fan running? Sometimes folks worry about adding fans, but the trade-off for dry air seems worth it.
- Also, anyone tried those humidity-sensing switches? Wondering if they’re actually reliable or just another gadget to break...

Cutting a vent into a closet wall or door does feel like a leap, but honestly, it’s one of those things that just works. I’ve seen folks try everything from moisture absorbers to leaving the door cracked, and nothing really compares to actual airflow. The “no-damage” tricks are fine for short-term, but if you’re dealing with persistent humidity, you’re just delaying the inevitable.

On the energy bill front, I’ve noticed that running a small exhaust fan in a closet barely moves the needle. Most of these fans are pretty low wattage - think bathroom fan territory. If you wire it to run only when needed (like with a timer or humidity sensor), the impact is even less. That said, if your house is already struggling with HVAC balance, adding more vents can sometimes throw things off. I’ve had clients who ended up with colder bedrooms because their closet vent was pulling too much air from the main room. It’s rare, but worth keeping in mind.

Humidity-sensing switches are kind of hit or miss in my experience. The higher-end ones tend to be reliable, but the cheap models can be finicky - sometimes they don’t kick on until it’s already muggy, or they’ll run forever after a single humid day. I usually recommend manual timers unless someone really wants set-it-and-forget-it convenience.

Curious if anyone’s tried integrating closet ventilation with their whole-house dehumidifier? Seems like overkill for most homes, but I’ve seen it done in older places where mold was a constant battle. Wondering if that’s actually more efficient than just running a fan...

Curious if anyone’s tried integrating closet ventilation with their whole-house dehumidifier? Seems like overkill for most homes, but I’ve seen it done in older places where mold was a constant battle.

I’ve actually set up a closet vent tied into a whole-house dehumidifier in a 1950s ranch with chronic mold issues. It wasn’t as complicated as I expected - ran a short duct from the closet to the main return, then let the dehumidifier handle the rest. The difference was night and day for both mold and that musty smell. Energy-wise, it didn’t spike bills much since the dehumidifier was already running for the rest of the house.

That said, I wouldn’t call it efficient unless you’re already running a dehumidifier for other reasons. For most people, a dedicated low-wattage fan with a manual timer is simpler and less likely to mess with your HVAC balance. I agree about humidity sensors being finicky - had one that would randomly run for hours after a rainy day, which got old fast.

If you’re in a really humid climate or have an older home with persistent issues, tying into the dehumidifier can be worth it. Otherwise, airflow plus a timer usually does the trick without overcomplicating things.

I’ve wondered about the impact on closet temps when you tie in a dehumidifier like that. Did you notice the closet getting colder or draftier? I tried a small fan once and it made my shoes feel chilly, which was weird. Curious if anyone’s tried venting just at the floor level instead of higher up - maybe that’d help with airflow without making everything feel like a meat locker.

- Been there with the chilly shoes - nothing like putting on ice blocks in the morning.
- Venting at floor level actually helped in my last place. Didn’t turn the closet into a walk-in fridge, just kept the air moving enough to keep things dry.
- Dehumidifier made it less muggy, but yeah, it did cool things down a bit. I tossed an old rug on the floor to keep my toes from freezing.
- Honestly, it’s a balancing act. Mold hates airflow, but so do my feet.
- You’re not alone in the battle - closets are weird little microclimates.
