"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."

"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. ⭐⭐⭐⭐⭐"

"JJ did a great job. He checked some ideas in the hopes of avoiding having to cut a hole in the ceiling, which I appreciated. He actually found other leaks in addition to the pin hole that caused the original stain and replaced the entire section. He also discovered our water pressure was well above code and reset it."

"I had them come out and swap out a 1/2 gas line to a 3/4 line for a new tankless water heater. Corey F was very kind and knowledgeable. He answered all my questions related and non related to the install and had me up and running with hot water in no time."
