    A close friend just had their windows done by your company and were very pleased with the quality and work. Also we have had some window and door work done by a competitor and when we compared costs, Sentry came in with better pricing.

    Your sales presentation by Chris is what made me choose Sentry. He explained to me how well your product is built and took the TIME to HELP me decide what colour and design to use on this house. He made me feel very comfortable and is very knowledgeable!

    We did some research and contacted a number of companies, but we felt that Sentry offered us what we were looking for at the most reasonable cost. It has been a wonderful and stress-free experience from our initial consultation with Joe to the installation crew waving goodbye as they drove away after the work was complete. We are very, very, very happy with our new patio door.
