My 10 year old gunite 30k freeform pool has developed several broken/loose coping. Even the ones not broken seems a bit hollow so I am think the entire coping may need to be replaced. Matching the coping isn't a concern unless the broken ones can be replaced if an expert says the other are fine. Any advice of a quality installer-someone in the know in the central NJ area, Ocean County? Appreciate any input, frequent reader, infrequent poster. Pool was uncovered for pics, not usually that dirty.
