Called every local window installer due to this being a very large and complex job. Did tons of research on Alside Windows and found them to be as good as other more expensive windows. Called big and small dealers/installers/contractors and chose Michal over others. He was quick to do bid and did not try to upsell like others. His installer was fast, clean and thorough. They sealed all openings and did outstanding trim work. They even took away all windows and clean entire place. They were working with 100yr old wooden windows in very bad shape, but replaced so all looks new.
