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 affiliate 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
