I choose this company after some research as I had some bad experience in the past. The CEO Charles come to my house and did analysis of water and check equipment and then give me the quote for regular service and improve my pool condition. I hired him for 90 days with agreement that if I do not like services will terminate his services. I am happy since last six months he is doing my pool services and happy with the services. I highly recommend him for pool service need. Shabbir Joher
