Windows have been called the “eyes of a building.” Their profile and proportion are as essential to a structure’s appearance as elements such as the cornice, siding, and trim. Although historic windows have sometimes been removed and replaced in the name of energy efficiency, our window conservation process can make old windows function as efficiently as replacements, while retaining the look and authenticity of an original historic facade. We offer comprehensive wood window conservation & restoration services, including paint removal, epoxy consolidation, frame repair, sash conservation and repair, sill repair, glazing and weather stripping.
