About a year ago, we had coping that was cracking and even had some of the panels inside the pool fall off. I hired a paver company that removed, regrouted, and replaced a bunch of the pavers. We had a deck refinisher re-do the surface of the deck with a light coating of some epoxy-like substance. Now, it's separating again at the same place. You can also see hairline cracks along the grout and a chunk of the paver fell off. I don't know who to even turn to for repair. I don't want to pay the paver people again because clearly what they did didn't work. Does anyone have any advice on who to call and how to fix this?
