How should I approach this?

After cleaning my parent’s garage, I noticed a few issues I’d like to address. The biggest being the first picture which is a large gap between the slab and the drywall that follows the stringers. The void appears to about a foot deep and from what I can see, it extends at least a few feet back under the base of the stairs. I considered filling it with spray foam insulation, but I’m unsure what the best approach is. The garage slab sits above the crawl space section of the basement. 2nd & 3rd pic: The bottom 1.5’ of the drywall seems to have be soft due to water damage, and needs to be replaced. When I fix it, should there be a gap between the base of the drywall and the slab? And if so, should I fill that joint? Any guidance will be greatly appreciated! submitted by /u/Ohstate23 [link] [comments]
