We just worked with Historical Windows to replace all of the windows in our landmark-protected coop apartment. We chose Historical Windows after about 6 separate window companies quoted but what won us was Historical Windows’s professionalism(specifically, their acct mgr, Brian) and focus on quality. They took time to understand what we wanted/didn’t want and they worked with us thru the quote process. Everyone else wanted to just give verbal quotes and were pretty shady. In the end, Historical Windows owned the entire landmark review process(which is time-consuming and requires prepared diagrams, presentations, etc) and once the approval came, Historical Windows promptly installed the windows. On-site they were considerate of our home and had a smart and talented foreman to oversee the whole thing. Now, we have wonderful Marvin windows that are attractive, quiet and insulating. We would work with Historical Windows again, hands-down!
