My pool is over 20 years old and maybe older. It was in very bad shape. We had it re-surfaced with Pebble Sheen applied by a licensed applicator. First they did a quick acid bath at the same time they where draining the pool. Then they did a partial chip out. They never offered option for full chip out. Almost 5-years later the floor of the pool grew a long crack and humped up. The pool never lost water even with the crack. Eventually the company came, drained my pool, cut a chunk out and determined the delamination problem is due to the old plaster deteriorating underneath the Pebble Sheen. The pool is under the 5 yr. warranty for delamination of Pebble Sheen. Because the sample they cut out shows plaster attached to Pebble Sheen then they claim it is not their fault. They say the whole pool needs a full chip out and they are willing to do this at half off. They say they do not know why my old plaster is deteriorating but it was sound when they applied the Pebble Sheen. I asked "Exactly how do you determine the plaster condition as sound before applying the Pebble Sheen?" They answered "The pool is checked for any loose and delaminated plaster and those are removed before the bondkote." This sounds to me like they take a guess and can not really know. I asked if the acid bath was to blame. They say no because the plaster is sticking to Pebble Sheen. They said partial chip outs are common. My delamination problem is uncommon but does happen. I asked WHY? Again they say they don't know. Does anyone know why? Do you believe they should have done a full chip out? I believe this is a faulty job and they should redo my pool for free? What should I do? Here are my options:
1.) Accept this offer to redo my pool at half price?
2.) Ask for a PebbleTec quality assurance rep to evaluate my pool? I am afraid they may be bias and I'll have to pay full price for redo pool. Has anyone done this?
3.) Offer to pay only 1/4 cost to covers full chip out.
4.) Go to court
