We researched on a bunch of pool companies on the internet and checked out which of them are around. We got quotes from a few of them before deciding to go with Anthony & Sylvan. They're the ones who installed our pool and have opened and closed for us. The people in the Maryland office were very nice and they got back right away. They helped me whenever I have questions. We were new to owning a pool, so we had a lot of questions in the beginning in trying to figure stuff out.
