Naylor Solar was recommended by my pool contractor when I had it re-plastered. They were the best price (by far) out of three estimates to replace the existing old, leaking & weathered solar on my roof. Terry's guy showed up early and got to work. I was very impressed with the installation and security of it, far better than the old original system. In six days, my (10K gallon) pool temp went from 71° to 90° in late April.
Highly recommended.
