Leaders in Energy Efficiency
Centennial Windows & Doors was the first window company in Canada to be ENERGY STAR® certified and has been praised for our excellence in energy efficiency. The ENERGY STAR Canada Awards recognize excellence in market transformation and the ongoing advancement of the “Five As” in Canada: availability, awareness, accessibility, affordability, and acceptability of energy-efficient products. We won the 2004 ENERGY STAR Manufacturer of the Year Award for all categories of energy saving products, nationwide. In May 2005, NRCan named Centennial the Canadian ENERGY STAR Retailer of the Year. No other company has won both of these awards! In June 2008, Centennial’s dedication to manufacturing and installing some of the most energy efficient windows was rewarded with the highest honour given by ENERGY STAR: the 2008 Award for Sustained Excellence! In 2014, we were again named the ENERGY STAR Manufacturer of the Year – Windows and Doors. Most recently in 2019, Centennial was named the winner of ENERGY STAR’s prestigious 2019 Manufacturer of the Year award.
Keystone Certified Products and Audited Quality Control
Under independent testing as part of the Keystone Fenestration Certification Program and Natural Resources Canada (NRCan), Centennial's complete line of custom replacement vinyl windows ranks as one of Canada's best windows for performance in Energy Ratings. This will save you money on your heating and cooling costs! Centennial is also one of a few companies in our industry that has volunteered to have its manufacturing process regularly audited and certified by Keystone Certifications, ensuring that you get the same high-quality windows every time!
Canadian Owned and Locally Operated
Centennial is a 100% Canadian owned company, employing over 200 Canadian experts in their fields. We bring jobs to the communities we serve and support them through many various charities.
We never hire subcontractors and all of our employees at Centennial Windows & Doors are fully covered by WSIB. This protects you and the worker should an accident happen while working at your home. It also helps to ensure that the installers receive proper safety training, carry safety equipment, and use it while on the job. In the event that something happens at your home, we have a minimum of $5 million dollars in liability insurance coverage for our jobsites.
