"A-1 is the best plumber in Marion. This is the second emergency call we have made and I could not be more pleased. We had a water main leaking. Mike and Seth came out, took the Fourth of July off, and were back Friday to solve the problem. Got it done within 35 minutes."
"Mike and his crew replaced a water heater in my Mom's house. In and out in about 90 minutes. Mike has about 50 years of experience and said he's installed over 23,000 water heaters. They triple-checked for any water/gas leaks before they left. Professional, quick, affordable."
"We highly recommend A-1 Plumbing for your complete crawlspace plumbing replacement. Not only did they replace all of the piping under the house but they also ran a new sewer line to the septic system. Thorough, on time, and left the property clean."
"I've known Mike for 40 years. He's been in the business for 50 years and has built a reputation that is second to none in Marion. Most importantly, he is a man of great faith and he lives it in his work and in how he treats his customers."
"Said they would be there at 8:30 a.m. they were there at 8:25. Fixed the leak quickly. Pricing was fair and upfront. Seth was professional and explained everything he was doing. Will absolutely call again. This is how every contractor should operate."
"Mike Jenner and team are beyond a God-send. Replaced our water softener, rebuilt our sump pump setup with proper-gauge piping, and re-routed water lines all in one day. A man of integrity. I wouldn't trust anyone else in Marion with my plumbing."

That is what your neighbors say about him.

Marion sits on limestone bedrock, giving us some of the hardest tap water in Ohio. That mineral buildup reduces water heater efficiency and can cut its lifespan in half. Ask us about bundling a Pentair water softener with your new heater install.
