Building Since 1970

CNO Pole Barns is a locally owned post-frame and steel building contractor out of Clarkston, Michigan. Three crews, four counties, and a build schedule we keep.

Who we are

CNO Pole Barns has been putting up post-frame buildings in southeast Michigan since 1970. Today the company runs three full-time crews out of Clarkston, building garages, barns, barndominiums, and pre-engineered steel buildings across Oakland, Genesee, Lapeer, and Macomb counties.

The company is locally owned, licensed and insured, and carries an A+ rating with the Better Business Bureau. Owner Zosim Serban quotes every job himself.

How we work

Reviews on Google keep mentioning the same things: the phone gets answered, the schedule holds up, and the crew doesn't leave a mess behind. You deal with the same people from the estimate to the final walkthrough, and the contract numbers don't move once the work starts.

"Zosim was on top of the project from start to finish and always available to review any questions that came up... After foundation and blocks were in place, the general structure was up in one day, the roof shingled the next morning... There were no surprises concerning financials."

"We had some issues being in the city with permits but Zosim was always on top of any problem that arose. Communication was phenomenal. I highly recommend this company."

The crews clean up when a job's done, too. It's a small thing that shows up in almost every review we get.

Common questions

Do you build through the winter?

Yes. The crews work year-round, weather permitting. One recent barn went up in the middle of winter so the owner's animals could move in before spring.

Who owns CNO Pole Barns today?

Zosim Serban owns and runs CNO today. Three crews do the actual building, and Zosim stays on the phone with you from the estimate through the final walkthrough.

Does CNO still build pole barns, or just steel now?

Post-frame is still most of what we build: garages, pole barns, horse barns, and barndominiums. Steel is a newer, second line of work, not a replacement for it.

Is CNO licensed and insured?

Yes. We're licensed, insured, and carry an A+ rating with the Better Business Bureau.

Post-frame or steel

Two ways to build

CNO started as a post-frame builder, and that's still most of what we do. We're also a certified Federal Steel Systems installer now, so steel is on the table too.
