"Our pool is 37 years old and we were trying to figure out how to keep the pool without spending lots of dollars on a replacement. Pro Basement offered an optional plan that will allow us to keep our pool and extend the life of the existing pool by repairing a problem area and fixing a drainage problem that caused an erosion on the one side. The company representatives immediately diagnosed the problem and installed a drainage system that will help with the pool and a water problem we had encountered due to the house settling. They gave us a starting date and flooded our yard with workers to excavate, install, and concrete their solution in a very short amount of time. I highly recommend and will use again if needed."

"Fred did a great job measuring the pool and the liner fits great! He also included 27 mil liners at the same cost that others charged an extra $300 over the 20 mil."
