All I can say about Shimmering Waters is OUTSTANDING!!!!!! They are one of, if not the best pool companies out there. I have had them clean my pool for too many years to count, and like all pools had a few problems and they handled them fast and efficient with little down time for swimming. They are extremely friendly and could go on for days about them. If you are looking look no further, Shimmering Waters is the last pool company that you will ever have to come out to your pool.
