What We Do

Energy Efficient Windows and Doors
Save on energy costs with doors and windows from Caledon Window & Door Systems Ltd.! With over 20 years of experience serving Caledon and the surrounding areas, we provide complete window and door replacements. By taking out the window instead of retrofitting it, we increase the energy efficiency of your home. For residential and commercial customers, we offer everything from natural wood windows to steel entry doors to patio doors, and everything in between. We work mainly with property management companies, offering high quality windows and doors from Vinyl Guard, built with high quality supplies from Gentek. Call us today and let’s talk about increasing the energy efficiency and value of your property!
