Built in Maine. Built to Last.

A hands-on approach

Jay Mongue started J.M. Builders to do residential construction the way it should be done: with the owner on every jobsite, every day. No layers of project managers, no surprises, no corners cut to chase the next bid.

We work with a tight circle of trusted Maine subcontractors we've built relationships with over years. That means the people framing your home are the same people you'll see at the lumberyard on Saturday. It matters.

From Shapleigh to Sanford and across southern Maine, we've built our reputation one home at a time. And the only marketing we've ever needed is the next-door neighbor who watched us work.
