Stylish and Energy-Efficient Windows and Doors for Homes in Cambridge, ON, and throughout the Tri-Cities Area

Homeowners in Cambridge, Ontario, and throughout the Tri-Cities area turn to Sentry Windows & Doors when they want to upgrade their homes with top-of-the-line windows and doors that are manufactured to stand up to the harsh Canadian weather. We are a family-owned and -operated window and door company that puts our customers’ needs first, and we offer products that are designed to offer four-season performance that other replacement windows and exterior doors can’t. What’s more, we stand behind our work with a no-nonsense lifetime warranty covering products and labour so our customers can enjoy added peace of mind.

Offering Outstanding Home Window and Door Replacements

If you would like to see the quality of the replacement windows and doors we offer, stop by our showroom at 1111 Franklin Blvd. in Cambridge. You will be able to see samples of our custom, 100-percent Canadian-made vinyl replacement windows, which are available in a variety of traditional styles. Since we know energy efficiency is always important, our windows feature insulated frames and ENERGY STAR®-certified low-e glass to make it easier for your heating and cooling systems to maintain a consistent indoor temperature year-round.

We also sell and install front entry and patio doors, with options available to fit any budget. You can choose from steel or fiberglass entry doors that offer equal protection against windborne debris impacts and forced entry attempts, and vinyl patio doors that can enhance the look and feel of your home.
