Robert Anderson came once a week for 4 weeks to maintain our small pool during our absence. The pool was equipped with automatic scrubber vacuum/skimmer (timer operated) and was super clean when we left. Robert's job was to clean pump filters, add necessary chemicals and water when needed and monitor equipment to verify all was working properly. The pool was full and still super clean when we returned, and when Robert checked in with us he reviewed with us everything he had done, including some o-ring and pressure release valve repairs (on older parts of the pump system) along with water quality checks, all verified with print-outs from the pool supply store that did the free water tests and sold him the new o-ring. He also took the time to show me exactly what he did, how to prevent the failure from happening again, what he would recommend for future best use of the new cleaning system and pump we had in place as well as the couple of "vintage" pieces that came with the pool when we bought the house 2 yrs ago. Robert presented us an itemized invoice that documented his charges for the weekly maintenance we had originally contracted for along with the cost of the new o-ring and his labor charges for repair work. He was very professional, very knowledgeable, very helpful, very reasonable and we would definitely hire him again!
