We are overjoyed with our new windows and sliding glass doors. We immediately noticed a significant reduction in road noise from nearby Maple Avenue as well as much less heat transfer that passed through our old windows on sunny days, all of which makes our home more comfortable and will reduce our heating and cooling costs. Paul and Derek were delightful to have with us during the four days of the installation process. They are personal, professional, respectful of us and our home, always cleaning up after their work. Last but not least, their work is impeccable. (Paul’s son also helped with the sliders). Thanks for having such fine, skilled people on your staff.
