Expensive work to change one sprinkler head that leaked but they did find the problem and fixed in in less than an hour. When we discovered this was a huge leak and insurance needed to see the sprinkler head for evidence… they had to bring the part back to be inspected by the claims person… and they did! It was $ 490 for the repair but they did it right first time. If you have leaking sprinkler head call this company. They know what they are doing.
