"I am VERY disappointed in my experience, even though it started out positively. Justin, the sales rep, was very helpful and I paid my deposit right after Christmas. However the customer service since it was installed has been less than optimal. The system has now shut down 3 times. I paid almost $12K for it. Este's says that the manufacturer has to send someone out to upgrade the computer. No one can tell me when that will be. Unacceptable."

"good"

"I am so happy with their work that fixed all our issues, even ones that weren’t originally on the request. Mr Chen is very honest and transparent. One couldn’t ask for more "

"Austin showed up to look at the issue caused by another plumber and our shower installer. He located the leak in the wall and quickly repaired the plumbing. He was in and out and the amazing service was at an incredibly reasonable price."

"I can't thank the guys enough for coming to the rescue. I started a toilet repair that should have been fairly easy, however….. So after realizing the job was too big for me I turned to Angi's list and they connected me to Garner Plumbing. They showed up that afternoon and had the job fixed within a half an hour or just a little more. I feel very confident in the work they did and they were very nice to work with. Would definitely recommend them to anyone needing plumbing service and the Jefferson, Athens, Winder area ."

"Honest and fair price. Great quick work."
