I called because I had a busted sprinkler head, but my system is 20 years old and had never been serviced, so I had him go over the whole system. He walked me through some problem areas, showed me a few minor problems that he was able to correct quickly (and at no charge), and laid out the work that needed to be done in detail. His team worked quickly and did an excellent job of cleaning up including replanting flowers that had been moved and putting the lawn back together. Definitely will call again if I need sprinkler help!
