The Apthorp is one of our favorite buildings to work in. We’re nearing our 500th window replacement in this magnificent landmark building. Most recently, we installed custom rectangular and arched mahogany double-hung windows from Parrett Windows & Doors in a penthouse apartment. The high performance windows are operated with brass weight and chains and are trickle vented.
