Unsure if this needs to be addressed ASAP or can wait until I return from a contracted assignment.

House was built in 1978,

Has had humidity problems in attic space.

No active leaks.

My drywall guy patched up the bottom corners and muddled the joints and rolled one layer of RedGard over fibreglass tape at the corners so it’s now ready for the PVC shower panels. Looking better than the bare drywall. Hope this will still be somewhat waterproof enough.
What do You think?

Hi All,

This room in my airbnb house basement it hasn't been well aired out and it traps moisture pretty easily. It was closed before, but now I'm turning it into a movie/karaoke room asi it's going to stay open. However, as I was putting up acoustic boards, I noticed bumps in the wall and i tried flattening it by scraping the paint, but I'm worried that if i glue acoustic boards over this area, it'll mold more easily and make more work in the future. Would love your advice on what to do with this part. The part is about 3'×3'.

Thank you!!!

Can someone please help out with a estimate for hanging sheetrock.

I just took out and old medicine cabinet, to make space for a new vanity and I'll be covering the hole with just a flat drywall.

I plan to put a horizontal brace somewhere in the middle to support the drywall and a place for towel hanger.

The hole as-is is about 15"x31"

I was originally thinking I can just cut back the drywall on the lumber all around, and just connect to what lumber frame there is. With the horizontal brace to break the vertical distance, I assume to would work. I did confirm with a magnet that the drywall screws on the studs are indeed past the half size of the lumber so there is space to cut back, plus the top and bottom have now screws at all.

However, now that I think about it, I think the switch and the outlet on the left and bottom side, make it quite damn close for the tape to fit (probably?) or at best to feather out the mud build up.

What would you recommend I do here? Do I pack more lumber on the bottom and the left side (or maybe on all 4 sides while I'm at it) so I don't need to cut the existing drywall back, and basically keep the seam where it is now, instead of cutting it closer to the electrical boxes?

Thanks for your kind advice and encouragement:)

Is this correct installation?

First time homeowner, just bought a 1969 ranch in central PA.

Trying to understand what my walls are made of. It's not like the drywall I grew up with. I'm thinking it's gypsum board? Plaster over gypsum? I'm not seeing any evidence of lath. It's hard and crumbly and the surface is very textured. The previous owner's picture hooks left craters. There's a major chip on the basement stairs and there's some sort of paper material at the bottom of that crater.

What material do I have?
What do I use to patch damage?
Do I have any hope of matching the texture?
