They installed the original pool and did the resurfacing. I like the way the close the pool, I've had them for quite awhile. I used to use Leslie for pool water check, which was very poor. Every time the checked the water had to buy chemicals and no explanation Tim at Anthony & Sylvan's Doylestown store was the greatest always explained what was going on. They have courteous, polite employees. They did good job, and answered any questions I had. I'm just very pleased. When employees leave the service department some one should shut down there voice mail or change the recording and forward it to someone who would answer the phones.
