Cutting inspection holes is smart, but I’d argue you’re better off just pulling the baseboards and drilling a few small holes near the floor. Less mess, and you can run fans or even snake a hose from a dehumidifier right in there. I’ve had tenants ignore musty smells and it always turns into a bigger problem—trust your nose, but don’t wait too long to act. Mold remediation is a nightmare for everyone involved.
Pulling baseboards and drilling holes does work, especially if you’re trying to minimize drywall repairs later. I had a basement flood last year—ended up using a combo of drilled holes and a rented commercial dehumidifier with a hose snaked right into the wall cavity. The key for me was catching it early before the musty smell even started. Once that odor sets in, it’s almost always mold lurking somewhere you can’t see. It’s tempting to just run fans, but unless you get airflow behind the walls, you’re only drying the surface.

Yeah, I learned that the hard way. First time I had water in the basement, I just set up a bunch of box fans and thought that would do it. Looked dry after a couple days, but about a week later, the baseboards started warping and I got that nasty musty smell. Ended up having to rip out a section of drywall anyway.
Pulling the baseboards and drilling holes is a pain, but honestly, it’s way easier than dealing with hidden mold or having to redo whole walls later. I’d also add—don’t forget about insulation if your basement walls are finished. That stuff holds moisture forever. If it’s soaked, you might have to pull it out.
Renting a dehumidifier made a huge difference for me too. The little home ones just don’t cut it for a big job. If you catch it quick and get air moving inside the walls, you can save yourself a lot of hassle down the line.
Totally get where you’re coming from. I’ve seen folks try to shortcut the process and it almost always comes back to bite them. One time, a client just ran fans for a week and thought they were in the clear—until they noticed mushrooms (yeah, actual mushrooms) popping up behind the couch a month later. Turns out, the insulation was still soaked and mold had a field day.
I agree about the dehumidifier—those big rental units pull out way more moisture than the little ones most people have at home. Sometimes I’ll even set up a couple of air movers pointing into holes at the base of the wall, just to make sure I’m getting airflow where it counts.
Curious if anyone’s tried those moisture meters you can get at hardware stores? I’ve used them a few times to check if studs and drywall are actually dry before closing things back up. Saved me from sealing in dampness more than once...
I’ve definitely used those moisture meters—honestly, they’re a game changer. One time I thought a wall was dry just by touch, then the meter said nope, still wetter than my socks after a pipe burst. Worth the extra step, for sure.
