I think this is linked to water intrusion through the covered window outside where the air conditioner is sitting.
I’m far from an expert on home renovations, so I’m not sure how we should proceed.
I’m worried that we’re going to find a much large problem once the existing drywall is removed.
We could:
cover that portion of the building with a tarp until we get drier weather
strip the wall down to the outer wall and completely seal off the window until the summer
replace the existing window with an openable one that an air conditioner (I think this might require a professional to fix, and I don’t know if it counts as structural.)
Does anyone have experience in this area or thoughts on how we should proceed?
So obviously, fix the wall and then put a hot tub in there.
I’d love to see a window in there so we can put in a legit air conditioner. Those 2 rooms were really hot when we looked at the place last August. Good news tho is the main part of the space was nice n’ cool.
I’ve updated the landlord and building manager on the situation and am waiting to hear back with a go-ahead to do the repairs or whatever we see fit to do at this stage.
Flooring and baseboard replacement can now proceed! Many thanks to @Petetheviking for lending us his top-notch contractor skills and @kleenpwr for additional work!
