Need for caulk around pool?
My pool (in NJ) was completed this summer. My question is about the foam-like material between the coping and the concrete. It was suggested to me by a pool co providing an estimate on a cover that because what I have now is pourous, water could get in there, expand, and cause problems with the tile/coping due to freezing. They suggested recaulking this "gap" with SECA Flex grade "A" pool caulk (for $1600). Seems like a lot for caulk. Any thoughts on this material that I have now, if this is truly a risk, and what it would take to do this myself. Seems odd that the standard product just installed needs to be replaced. Thank you
