What's the best way to fill these holes in my laundry room?
(sh.itjust.works)
My goal is to keep hot/cool air from seeping between floors. Is canned spray foam the way to go? Any recommendations? Pest resistance is a bonus.
If it were me I’d design and 3D print something to mount around it that would be held together with either rubber bands or possible screwed together. But I realize that is outside of most people’s skillset. Maybe you could get somebody to design something and get it printed online. But I guarantee it would take a couple of iterations and probably cost upwards of a $100.
Maybe something like this…
