Cracks in the wall

I'm trying to help out my neighbor with some renovation, and she says there is a crack in the kitchen wall that allows smells from neighboring apartmentments' kitchens to get in. She's also complaining of mice that have found a way through. There is some insulating foam that she put in, but it's not working too well. What exactly do I need to do to get a good seal from both mice and odors. I've got a spare bucket of joint compound which I thought about using but not sure if that will really work.

The cracks and gaps you are seeing are in the cabinet. Sealing them will yeild modest results. You need access to the wall and floor behind the cabinet to find the holes & gaps in the wall and floor. Since you have a mouse problem I would seal them up with steel or aluminum flashing. Then caulk the edges to help stop airflow better.

You'd want something flat, most any sheet metal will work. Mice can't chew their way thru metal but can if you patched a hole with wood.

Maybe something like a corner bead? It's prety flexible so I can probably just unfold it. There is also aluminum sheets on sale, but I'm not sure how I would cut it into strips.

You can buy a short roll of aluminum flashing for under $10 but any scrap sheet metal will also work. You cut it with tin snips or aviation sheers, IMO the latter works best.

I couldn't find any rolls at home depot, so I just got a large corner bead. Do you think I should cover it with compound because it's going to be under a sink area, so any chance it'll rust if I don't?

The metal corner bead is galvanized so it shouldn't rust unless it's repeatedly exposed to moisture.
