These before and after pictures show a commercial window installation project at Smith College in Northampton, MjA performed on a subcontracting basis by TR Wells Custom Framers. The entire dorms windows were removed and replaced for a total of 128 windows. The challenge on this project was to install the windows in an existing masonry opening, sealing and caulking the exterior in order to pass an extremely rigid water and air penetration test performed by an independent contractor hired directly by Smith College. The air and water test results were extraordinary and TR Wells passed on the first attempt due to significant planning and care during the install. TR Wells was also responsible for installing the interior trim on the windows as well.
