Attractive and Energy-Efficient Windows and Doors for Homes in the Chatham, ON, Area

The home improvement specialists at Sentry Windows & Doors offer a combination of outstanding products and service that is hard for the competition to match. We install high-quality replacement windows and doors on homes throughout the Chatham, Ontario, area, and have earned recognition on multiple occasions for the exceptional level of service we provide. This includes twice being nominated for the Better Business Bureau’s Business Integrity Awards. Additionally, we offer a no-nonsense lifetime warranty covering all products and labour, so you can rest easy knowing your investment is protected.

Home Windows and Doors Built to Handle the Ontario Climate

When a home isn’t as energy efficient as it could be, old windows and doors that allow drafts to enter and heat to escape are often the culprits. At Sentry, we offer products that are manufactured to perform throughout all four seasons, making it easier for your heating and cooling systems to maintain a consistent interior temperature. Our windows are manufactured in Canada under our specifications using 100-percent virgin PVC for the frames, so they will never fade, crack, warp, or chalk. They also feature ENERGY STAR®-certified low-e glass and are available in a wide array of styles.

Our front entry door options include heavy-duty steel doors with smooth or embossed finishes, or, if you’re more interested in the look of natural wood, we offer fiberglass doors in several different woodgrain finishes. Additionally, we install vinyl patio doors that are as stylish as they are durable and can be customized to add a personal touch to your home.

If you would like to learn more about the exceptional windows and doors we install, contact Sentry Windows & Doors today or visit our showroom at 701 St. Clair Street in Chatham.
