Kempenfelt Windows & Doors in Newmarket and Barrie provides customers with premium quality, high performance products and outstanding service. What started as a simple vision two decades ago in Barrie is what defines us as Barrie's favourite window & door company 21 years running. We bring that same commitment to Newmarket. Our professionals work with you to determine an appropriate solution for your unique requirements, providing guidance every step of the way. Although we install windows, entry and patio doors and garage doors of exceptional quality, that doesn't mean they come with a high price tag. We ensure the best product possible for the lowest price possible every day.
