"Nathan came after our warranty company sent a crappy company LYNNCO who misdiagnosed and did nothing to try to solve our problem. We were almost a month without a washer fooling with them. I was connected with Nathan and he was very understanding and patient to our initial desire to have the warranty company rectify the situation-stay away from AHS. We ended up calling him back and he came out and worked diligently to figure out what our issue was. It was a combination of things but he did get our drain unclogged and our washer working without overflowing onto the floor! It was not the plumbing vent like the first company said. Thanks Nathan."

"I had a tankless water heater installed but needed the gas line to be dug from the other side of the house for it to be connected. The job was complicated but Luke and his crew from Mr. Rooter did a great job! I would totally hire them again for any plumbing needs. "

"Kelton and Bobby provided a very professional install on my new tankless water heater. They worked with me on the price and stayed late to make sure I knew what each feature did and the recommended maintenance schedules. Highly recommended!"

"I needed my laundry room drain unclogged. I posted the job on Saturday night for work to be done on Tuesday morning. Jim called Sunday morning, said he was available that day. Came out relatively quick and the job was done within the hour. I highly recommend Jim. I'm certainly going to give him a call the next time I need work done."

"Main water line ruptured we were without water. Winkle's responded to late evening call and came out next day and repaired, while pointing out the line had degraded (nothing external such as root caused the rupture) and suggested it would need replaced at some time in the future. We decided to proceed and they arrived on time, did an excellent job, replaced the old line and the old water meter as well, along with a small pin leak underneath the home's crawl space when connecting the new supply line. Very happy with their services, highly recommend."
