We were originally scheduled to have our system shut down in mid-November. However, after learning the temperature was going to reach below freezing, they called us requesting to schedule early to prevent our system from being damaged. They did everything possible to accommodate us and we were able to get the system shut down early. This is the first time we have used this company and were happy to see they took a proactive stance in getting this work complete.

Had a major line break in our sprinkling system. Professional Irrigation employee spent several hours getting it repaired and it now works great. The lawn was torn up but put back as neatly as could have been. Spread some grass seed in the repaired area and we are good to go. I would highly recommend Professional Irrigation if anyone is in need of service.
