"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."

"Update from 20 Jan 2026: I`ve been a repeat customer of Keep Smiling Plumber, Electrical, Heating and Cooling in the past for several home-related repairs. After having an unfortunate experience with Keep Smiling PEHC during my most recent service, I had some misgivings about the company and whether I would return as a customer. In regards to their customer service, everyone that I`ve engaged with (technicians, onsite supervisor, receptionist) has always been professional and courteous which goes a long way with me. The issue that I had was technical in nature and left me with some dissatisfaction regarding the quality of work. After speaking with leadership of this organization Mr. Powell and Ms. Amy ,I believe that they hold the highest standards and expectations for their employees and ensure that any work-related issues are duly addressed/resolved. I can sincerely say that they have regained my confidence and trust in contacting them in the future for my future HVAC, Electrical and Plumbing home needs. The manager I spoke with told me that there wasn`t any way the damage of the pump could come from the technician doing a drain and flush of the water heater. He told me that it would cost $1200 to replace the pump on the water heater. After speaking with the manager at Keep Smiling, I called another company which I`ve seen before in the community and spoke with a plumber and explained to him what happened. The technician at the other company told me that the pump could definitely be damaged if the pump was still plugged up and not turned off while the water heater was being drained and flush. I called the manager at Keep Smiling and shared those details with him and he replied that he understands what I`m saying but there was nothing he could do about it. I told him that I don`t have any reason to lie about any of this and felt very frustrated and cheated by the fact that I went in expecting for them to do a maintenance check for $59 for plumbing but ended up spending a $1000 for new.

"The reason why I give them 5 stars is because they respond and install my water heater in Less than 24 hours. The technician who run my call show that he has knowledge about that job. When the job was done he explained how the new water heater work and what to if help is need it. He also explained and showed me the deficiency of the valves and recomended to be changed. I when ahead and take his recommdation. I took their number from the broken water heater that was installed 23 year ago. If I ever need plumbing service I will call then in a heartbeat."

"Morgan Pitman provided same day service to install a 50 gal tall gas water heater. Excellent customer service and workmanship while providing maintenance education. Old heater lasted 12 years so the cost and installation for replacement was staggering but less than competitors."

"These's guys rock! Me and my family was on vacation and came home to a disaster. Our water pipe at our water heater busted and flooded. We called rooter pro plumbing ga at 10pm at night and they were there in 40 minutes. They fixed the issues and had a team out to clean up and deal with our insurance. We recommend them over anyone."

"I am a Realtor and I refer Jake to all of my clients. He has also done numerous jobs at my home including finding a void in our out going system, jacking out a cement pad in our home and replacing pipe that had deteriorated. He also installed new plumbing and ejector pump for a bathroom that I am building. You will not find a more honest and decent person in the plumbing trade."

"Justin and Phil provided me with the best quote for replacing my old water heater. They even diagnosed the problem to fix the thermostat in my water heater and gave me a quote if I wanted to stick with my old water heater. I appreciate that level of transparency. I decided to replace my water heater since it was an old unit. They did a solid job replacing it. My water heater is located in my attic and they handled the job like a pro."
