Cobourg, Ontario
We’ve been building in Cobourg since 1999. This is our home.
Cobourg Construction was started in Cobourg and has never left. The Merson family and their team have built custom homes, completed renovations, and delivered commercial projects throughout the town and the surrounding area for 25 years. When you hire us, you’re hiring people who live and work here, people who have a stake in this community and a reputation to protect in it.
We know Cobourg’s heritage designations, its building department, its local contractors, and its neighbourhoods. That local knowledge means faster approvals, better trade partnerships, and construction that fits the character of this town.

About Cobourg Construction
The Merson family. Cobourg-born. 25 years of building here.
Cobourg Construction was founded in 1999 with a simple premise: do the work right, stand behind it, and treat every client the way you’d want your own family treated. That hasn’t changed in 25 years.
We’re not a GTA company expanding into Northumberland. We’re a Cobourg company, always have been. Our reputation is local, our trades are local, and our investment in this community is real.
