"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 ."
