I am a senior and am so happy with my Mascotte security door. I knew I would like the door but had not anticipated the peace of mind the door has given me. The process of measuring/installation was completed in a professional, timely manner; Chris & Luke were great! The hardest part was deciding on a design and color as there are so many to choose from. I highly recommend these doors to everyone and can’t wait to get one for my patio slider.
