About Us

Hands-On Construction From the Ground Up

J-PAC Construction is a family-named, hands-on construction company led by owner Jeff Cotnoir. Our crew does the work ourselves, from preparing the site and placing concrete to restoring the surrounding property when the job is complete.
We plan the order of work, explain what comes next, and keep the job site organized each day. The result is dependable work with less disruption to your home or business.
