Jack was great. He was smart, you know?He was flexible about timing and worked steadily and logically in troubleshooting the problem, asking us for relevant info about the situation and explaining what he was doing and why, as he went through each step. He was friendly and easy to talk to -- I learned a lot along the way, realized how complicated an irrigation system is, and how important it is to have someone with Jack's expertise and experience do the job. He identified the problem and gave an estimate on the fix, let me know that it was not necessary to do it right away. Even better, he was able to establish that the problem with our system was NOT the cause of our 51 thousand (!) gallon water bill, and gave us a detailed letter for SAWS to that effect, so they will adjust our payment. (Speaking of payments, Jack's prices were more than reasonable, so, satisfaction all around) When spring rolls around and we want to start using the sprinklers again, we'll be calling you, Jack!
