They installed a liner, filter and pump. I never got my receipt or warranty papers after calling and emailing over an Over. They left sharp objects under my liner he said he would fix it so many times never fixed the problem. Then next season I had them open my pool and they cracked my filter. It could have been fixed with warranty papers but he never gave them to me. I have emails to prove everything I'm saying is correct after two years not fixing my pool or filter I had to pay for a new filter out of pocket and now this year the sharp objects broke my liner and it's only been a couple years. I have to do this all over again! do yourself a favor and stay away bad company!
