Anthony & Sylvan Pools built my pool and since then, we have been using them for opening and closing as well as some add-on equipment installation. When the installer had the add-on equipment installed, he noted that there was a need to upgrade one piece of the equipment. They did not have that with them and it was an oversight from the original review of what was required. Basically, when they closed the pool, they took out the wrong piece and I've got all my accounts that when they come and open the pool in spring, they'll bring the additional capacity with them and put that in place at no charge. Otherwise, the guys that do the work are quick and efficient. We don't have to be here when they do the work, but if we are, they're really good at explaining what they're doing and making sure that if I have any questions, those questions get answered before they leave. Their work is also well done, putting things together.
