I live in the Philadelphia region and had Anthony and Sylvan put in our pool last year and were very happy with them. They were very easy to work with and any problems that did arise were minor and were resolved within hours. I asked them for the worse case scenario in my quote such as an extra day excavating, hitting rock, hitting water, ect so that there would be no surprises. We actually had zero surprises so we walked away smiling.
