Be aware of fraudulent door-to-door sales people.
We have received notice of an unauthorized company in the Windsor and Brantford areas that is canvassing door-to-door claiming to be a subsidiary of Centennial Windows & Doors. Centennial does not have subsidiaries or affiliated companies, and does not engage in door-to-door selling. Centennial sales agents arrive at customers' homes at pre-scheduled times (arranged between both the homeowner and Centennial). If you have been approached by a company claiming to be a subsidiary of Centennial Windows & Doors, please contact us at 1-800-265-1913 or info@centennialwindows.com.
