After my 5/22/2017 review, Jason from Sprinkler Doctors called and graciously apologized for not fixing the original problem. He and his company wanted to make it right, so another appointment was set up.. Jason and Steve came out and reviewed all the lawn sprinklers and the control box. They replaced a head that was not covering an area of the yard correctly. They did everything they could to ensure that I was satisfied with their work. At this time I am satisfied with their work. They asked that I give there adjustments a week of irrigating to make sure the sprinklers were set correctly and if any issue, to call them back out. Will consider Sprinkler Doctors for future work.
