Authorized Dealer

Sentry Door, Inc. is a unique garage door installation and service company. We’ve stressed quality components, excellent installations, and then, if it’s still needed, competent service. Our team is professional, well-trained, friendly and customer oriented.

Sentry, begun and owned by James Martin, has built its growth on that approach and reputation. Most days in Ontario, we’re installing new doors that will work well for years. After all, “doors shouldn’t waste your time.” Contact us today for garage door installations or service. Sentry Doors is your local Richards-Wilcox dealer
