Found Green Valley Irrigation on Homestars and saw all the great reviews. I needed a sprinkler system for our front and back yard. John came out to give a quote and it was obvious he had the experience to do the job right. We have an irregular shaped lot and he knew where to position the heads (40+) to hit over blade of grass and every plant in every beds we have. John and his crew were very professional on the installation, clean up and demonstration of the system. And he had the best price of 3 different companies we were quoted by. My highest recommendation for John and Green Valley.
