My daughter and her husband in Las Vegas have a large 30,000+ gallon pool and spa. It was in bad shape after some filter and power problems. Dark green with algae and badly out of condition. We were told by other services that the whole pool would have to be drained and cleaned out. Very expensive. Jorge and his son however were able to take care of the problem without draining. They worked every day for a week on it but the cost was very fair and reasonable. I have hired them for weekly service, which is also quite fair, especially considering it's a difficult pool to maintain. Other services I've had quit on me. I highly recommend Jorge to any pool owner.
