"They are the best, they were professional and honest and quality work, we've been using them for over 20 years. We've never had to have them return to fix the same problem. When he was working on the pipe that had been leaking he even cleaned up the water after the repair."

"I used Greenlee to replace my water heater. They replied to my inquiry for service very quickly, even though it was after normal business hours. They were responsive and professional assisting me in determining the best solution for me. They arrived quickly and on time. Their work was fast and they did a great job of removing my old water heater and installing the new one. Everyone with whom I had contact was friendly and professional. They will be handling any future plumbing work that I have."

"Navien Tankless Hot water heater was not putting out adequate hot water. Matthew Jones was able to troubleshoot the system, finding a valve with a bad o-ring. The valve was replaced and we have plenty of hot water now. Matt was very courteous, friendly and most of all a confident worker."
