"It went well! Matt and TC at Plumb Life ATL are very professional and communicative. Matt called the day before to let us know when the plumber, TC would be arriving. On the day we were scheduled, TC called an hour before he was scheduled to let us know when he'd be arriving. TC was very punctual and determined to find the source of our water leak. He removed the water heater in less than no time. Then he explained to my wife and I that he needed to cut into the wall to find the leak. He then neatly cut into the wall and found rusty nails all throughout our piping. He removed the damaged pipe and neatly installed new piping in that area. We no longer have a water leak issue thanks to TC and Matt. Matt was also very communicative from the onset to the conclusion of the work. We highly recommend their services. ⭐⭐⭐⭐⭐"

"I had a tankless water heater that needed to be looked at. I wasn't getting any hot water. Everyone i called tried to give me some crazy prices. Rooter Pro Xpress called me and said they could get someone out here the same day. He came out and gave me a quote. It wasn't to bad of a price he was able to install a new gas tankless water heater and said it would save some energy. I was very happy with the work. Will be calling again !"

"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."

"Starting with my salesman Stan, who was extremely knowledgeable and patient through an easy installation and then my plumbing Overview by Blake who was extremely thorough it has been great working with this company. Blake even noticed that my recent water heater installation by another company was not up to code so I had to call them to come back. He even went so far as to email me information that I could share with the other company to make sure they change the errors. Whether you need AC or plumbing this is a great company."
