"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."

"Great customer service, helped very short notice, explained every step of the situation. Would highly recommend."

"Needed a quote on replacing my HVAC system after being told by another company it needed replaced. That companies quote for 13000 dollars for a manufactured home system. I chose to get a second opinion, the tech came out and had it working in short time!! Would highly recommend!!"

"Nathan did a great job replacing our old cast iron drains with pvc. He was courteous and knows his stuff. Great job!"

"SMK plumbing did a great job for me with a whole house water re-plumbing & main water line from the street. The team was efficient, professional, and polite. Job was started and completed in one day. They even moved the whole house shut off and pressure valve to a very easy to get to location."

"Show up at time they stated would be there. Looked at job gave a price and did a great job in fixing the problem. Will use them again."

"Had a leak on a water line in our yard. It was an old metal pipe that was corroded and we got it all replaced."

"They installed 2 new water heaters with a circulation system to provide virtually instant and endless hot water. We went this route because our house is all electric and electric tankless water heaters arenâ t really up to the task. They also had to subcontract electrical work to supply the necessary power upgrade. We expected this to be a 1 day job, but the electrician didnâ t have everything required so it dragged out to a second dayâ ¦ meaning another day out of work so we could be there to give them access to the property. Then later when we tried to use hot water for a bath, there was only about 2 minutes of hot. Turns out the circulation system was installed backwards, so the circulating water was hot, but once the pipes were depleted, cold water was fed to the spigots. Disappointing, but to their credit, someone came out Saturday, diagnosed the problem and fixed it. Overall, mildly annoying and a bit careless, but everyone was friendly and responsive, and the end result appears to be just what we wanted."
