I have a ~25 year old ~15,000 gallon fiberglass pool and am replacing the pool decking and underlying concrete this fall. The coping is concrete and and I am wondering if we should replace this too? At the end of last season it was in pretty good condition overall with 1 noticeable hairline crack. Other than that it probably could be resealed in the joints in some spots. I asked our pool guy and he said if we don’t do the decking + the coping at the same time we will regret it. We could definitely get more life out of the coping, but I don’t want to deal with any headaches down the road. Any insight would be appreciated!
