Our swimming pool was built in 1970's by Anthony & Sylvan Pool. We also got them for our pool renovation because we personally did some looking around and felt that their prices were competitive and they had a lot of experience. Their consultant was reasonable, he's not perfect but quite knowledgeable. So, we had the whole surface renovated. It was re-plastered, re-coated and repaired. Their coordinator told us how it would go and they were completely accurate so we knew when we would expect people to arrive. Four crews were involved with their particular sub-specialties. There were a few minor irritations and errors in what they'd do versus the original plan but we were there to correct them and it was fixed. I never had to paint it again, it did hold up to the temperature and the chlorine that we usually keep it at, and looks really pretty. It's an old pool but it looks like a new pool.
