My sprinkler system needed a major overhaul; I had broken sprinkler heads, a couple of leaks and some that just weren't working at all. Jake gave me an estimate that included adding a new terminal with new wiring; correcting the placement of current sprinkler heads; adding additional ones and making the whole thing work well. He and Ben did a great job; were finished the same day, and will check back after I water the first time to make sure no adjustments are needed (if they are, Jake has promised to fix it). I also received a one year warranty on everything, so felt comfortable with this. I think they did a good job and would recommend Jake Harrington to anyone who needs work on their sprinkler system (they also work on outside lighting).
