I moved into a house that had irrigation system installed by Submatic. They had been doing fall and spring service for me at $100 each time. The technician that came into do the blow-out gave vague instructions to my spouse that resulted in her shutting off the main valve instead of the sprinkler valve. When the technician left my spouse reopened the valve. When I came home I saw the flooded front yard from the tap that was left open by the technician and understood what had happened. I called Submatic and they said they will rectify the problem at no charge by reperforming the blow-out. However, weeks lager I got another bill for $100. I called reminded them about the discussion we had – they had no recollection of this. They took absolutely no responsibility for the lazy technician that did not want to take off his boots to come and do the job right. Also did not go by their word. This was a blessing in disguise; I looked up another company that was rated highly on Homestars. It cost $60 and the guy was a pleasure to deal with -- takes pride in this work and stands by it. Based on my experience, I would not recommend Submatic to anyone.
