Paul was cleaning our neighbors pool and I asked if he would come and look at my pool cleaner which was unusually loud.(my husband and I were debating if it was supposed to be that loud!) He came right over, adjusted the settings, explained what he did and offered me his card. He did not charge me and was very nice about telling me about his service and what he does. If we do choose to have a weekly service, I would call him for sure. He was very gracious and I appreciated his help very much!
