I had my large spa built in 2008 and have totally enjoyed it. The unusual location of the spa created some interesting construction challenges for Jack and his workers. The spa is located on a hill in front of my house with large boulders and blue granite below ground. The boulders were incorporated into the waterfall and the blue granite was removed by a specialized drilling outfit that Jack located. Despite the construction challenges Jack and his team completed the project on time and on budget. Jessica, in the main office, has been very helpful with questions regarding the chlorinator (saltwater system) and other equipment. I would recommend Superior Pools to any and all prospective pool/spa purchasers.
