Mason is personable and did show up reliably once a week. He did not reveal, however, that he is inexperienced with salt system pools and after two months was unable to get the chemicals correct. He came on Wednesdays, but on 3 separate weeks algae was growing by Saturday morning. When I called and asked him to please come and see what the problem was, he was unable/unwilling to make an extra stop on Saturday or even Monday to correct problem. He charged almost double what was quoted for chemicals or equipment adjustments that were either unnecessary or ineffective. If you have a simple pool, perhaps Mason is the right pool person. If you have a sophisticated system of any kind, I recommend you choose someone more experienced and willing to go the extra mile. read more
