Celebrating 42 Years of Expertise

Centennial Windows & Doors has been serving local Ontario communities with products we manufacture ourselves since 1981.

We Manufacture

Not all replacement windows and doors are made the same. At Centennial, our products are measured and manufactured specifically for your home, which allows for proper installation and long-term, exceptional product-performance.

The Best Warranty. Period.

We stand behind our product quality and installation 100%. That’s why we’re proud to offer the most comprehensive warranty in the industry, covering both the products and installation of your replacement windows and doors for as long as you own your home.

Expert Installation

Even the highest rated windows and doors are only as good as their installation. That’s why we include installation by our expertly trained installers in the cost of all of our windows and doors.

ENERGY STAR® Certified

As the first window and door company in Canada to be ENERGY STAR® certified, our products are independently certified to use less energy and reduce the emissions that contribute to climate change.

The Best Warranty. Period.
