Hopefully I chose the right section to post this in...
I've been renting a townhome this year and have discovered that its bay window seat is incredibly drafty: the inside seat part is sinking down in one corner (getting soft from being exposed to outside moisture, I think), leaving a bit of a hole and a draft coming in from outside. The outside surface of the seat's underside isn't sealed up or anything, so cold air's coming in pretty steadily when I put my hand against the sinking part.
I definitely want to fix the problem, but since I'm only renting for another 6 months at this point I don't particularly want to drag an expensive contractor in, etc. From what I'm reading online the solution could be as simple as getting some insulating foam cut to an appropriate size, slapping it under the outside floor, and then covering that up with something?
I'm new to this sort of thing though, so was hoping someone might be able to point me in the right direction for a solution that 1) is inexpensive, 2) I can do myself, and 3) doesn't involve taking the seat or walls apart but rather just insulating what's already there.
