About us
A Legacy of Craftsmanship, Rooted in Canadian Excellence
When it comes to interior doors, we believe quality isn’t just seen — it’s felt. It’s the quiet click of a well-built door, the smooth finish beneath your fingertips, and the peace of mind knowing you’ve chosen a product built to last. That’s the philosophy behind everything we do.
With over 2 decades of combined experience in the door and trim industry, our team brings unmatched expertise and dedication to every step of the process — from design to delivery. But our story doesn’t start here. We’re proud to carry forward the legacy of two of Ontario’s most respected names in the field: Madawaska Doors and Trim and Capital Door. Together, these companies represent more than 80 years of industry history, craftsmanship, and customer trust — a foundation we’re proud to build upon.
Ontario-Based Manufacturing, National-Quality Standards
Our doors are manufactured right here in Ontario, using carefully selected premium materials and a focus on precision internal construction. We’re not interested in cutting corners — we’re here to raise the bar. Every door is thoughtfully engineered to meet the demands of modern living, combining long-lasting durability with timeless design.
From the inside out, our products are built to perform
