Installation Matters

One of the biggest factors behind the performance and longevity of windows and doors lies in their installation. That’s why our expert installers are a part of the Centennial family, not external subcontractors. This commitment to in-house expertise ensures that every window and door holds up to our own high standards.

Installation Matters

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.
