48 Years. Over 23,000 Water Heaters. One Reputation.
A-1 Plumbing has been serving Marion, Ohio since 1966 — back when the city's water main was laid in many of the neighborhoods we still service today. Owner Mike Jenner joined the company as a young plumber and has spent nearly five decades building a reputation that, in his own words, "isn't about marketing — it's just showing up and doing the job right."
Today, A-1 is a family operation. Mike runs every major job personally, supported by son Chris (General Manager) and a team of experienced technicians including Seth and Todd, who are regularly named by customers in their five-star reviews. In a market where national plumbing chains promise consistency and deliver anonymity, A-1 delivers both consistency and the actual plumber your neighbor recommended by name.
"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."
— Tom Kirby, Marion, OH
