This company installed my liner in 2005. They were reasonable in price. That is where their performance ends. They were asked to repair some minor cracks that my automated pool cleaner hangs on. The new liner went in and the cracks were still there. I would have gladly paid extra for fifteen minutes of crack filling. They also left the liner retaining bead (7 feet) hanging off the edge, floating in the pool. The liner had a major wrinkle. They said it would work its way out. It never did. When I called them to ask that the liner retainer bead installation be completed, it took two weeks before they returned to seat it. Two summers ago, my laterals blew out and the filter sand all went into the shallow end. Though I carefully shoveled it out, I must have sliced some small holes in the liner. Though my experience was not that great with Pure Aqua, since they installed the liner, I called them and explained that I was loosing an inch a day (perhaps 1000 gallons a day into my hill and expressed urgency. I asked for a repair diver to come out. Still adding water every day, two weeks went by. I called again and was told that my request "slipped through the cracks." A week later they sent a guy out. My son said the guy was messing around with my filter. Two more weeks went by as I continued to loose water into my hillside at 1000 gallons a day. Finally a guy representing himself as the owner came out and said, "frankly sir we don't have a diver right now but we are trying to hire one." I asked who I should call. He would not make a recommendation. He suggested using the yellow pages. I went to McCarthy Pools in Southborough. They had it fixed in three days. I was very patient through the whole ordeal. A few months later I received a bill for about $175 from Pure Aqua. I called and asked to talk to the owner. The secretary was not helpful and said I needed to pay. The next month I received another bill. I called again and nicely asked to talk to the owner. This time the woman was short with me and said to pay the bill. The next month I received another bill. Each time I called and each time the secretary became more and more harsh. Frankly, she is mean as a wounded rattle snake. After many months of my attempts to clear this up, they sued me for $175 in small claims court in Waltham. The judge was unsympathetic and I paid. If you are all about price, go with these guys. I pay a little more now for service and am very happy with McCarthy Pool.
