Second Measure

Once you have decided on the perfect windows and doors for your home, one of our expertly trained measure technicians will assess all of the openings for a second time, before manufacturing begins. We truly believe in measuring twice and cutting once — we always do the required upfront work to check our measurements twice before we build so that we can ensure your new windows and doors systems are a perfect fit.

Custom Manufacturing

Once we’ve confirmed our measurements, we start to custom manufacture your premium windows and door systems. Our state-of-the art manufacturing facilities are located in London, ON, and combine the latest technological advancements with precise, hands-on attention to detail. Before your products leave our facility, they’re double checked by hand to ensure that they are free from defects and match the specifications of your individual order.

Even the highest quality products will only perform to their promised standards if they’re properly installed. That’s why we include installation by our expertly trained Centennial installers in the cost of all replacement windows and doors. We do not hire subcontractors. We finish each window and door with fully painted interior trim so that there’s nothing left for you to do once we leave. We’ll also clean the windows and doors that we installed, show you their proper operation, and provide full warranty and product certification documentation.


Our No Fine Print Warranty is the most comprehensive in our industry. Our warranty covers both the products and the installation of your replacement windows and doors for as long as you own your home and has no pro-rated terms. If you choose to sell your home within 10 years of purchasing Centennial windows and doors, the warranty can be transferred to the new homeowners. Just have the new homeowners give us a call and we’ll take care of the rest.
