Thanks for the reply. The pool never had any waterline tile and that is something I will be adding. Good point on the coping. Many pieces are loose and can and would be removed beforehand if needed.
The plastering co. has been doing business 20+ years and he referes the crack reparing co, who seems reputible, although pricey. But I agree, they should be checked out.
I didn't get much in this section so I reposted in the fiberglass pool section but < again, thank you for your reply.
