99 High Street

99 High Street, also known as the Keystone Building was designed by Emery Roth & Sons in 1971 and is notable for its rounded corners and travertine facade.

Patriot Restoration was commissioned to provide complete scaffold access to the entire building facade as part of a $14.4 Million facade restoration and window replacement project. Patriot worked with the architect to develop the window replacement strategy and travertine facade restoration program. Patriot was responsible for and handled all site safety, scaffold access, sidewalk bridging, travertine repairs and sealant replacement along with coordination for window replacement, which was performed at night to minimize disruption to the building tenants. The three year project, replaced all windows in the building, restored all of the travertine facades and replaced all building sealants.
