Hello. Buying a home close soon. While inspecting the pool i noticed that the white coping is showing its age. One part by the deep end you can see is like 1 inch inward for an eight foot section then the rest of the pool. You can visually see the liner come out along with the coping about half an inch from the rest of the pool. There is also 2 cracks running down were it has pulled towards the pool. Is there any way to pull the deck and coping back? Will this harm the pool?
