Home Advisor gave me two referrals the morning of May 7th. I I called J & J Services and Luis made an appointment to come out to see the property between 3:00 and 4:00 the same day. He arrived on time and sized up the landscape & our sprinkler location needs. The installation was done on May 14th. He and his crew arrived right on time, first thing in the morning. They were fast and efficient, finishing the complete install the same day. His estimate was a little on the higher side, but the work was excellent. He has also come out to assist us in tweaking a couple of sections at no charge. Highly recommend.
