Exterior Envelope Inspection
The sandstone cladding on this downtown building was exhibiting severe deterioration. In urban environments, the natural weathering of sandstone is accelerated, which, in this case, resulted in face spalling of the ashlar units and deep cracks in the decorative sills and beltcourses. Additionally, water leakage was occurring at the top floor, below the integral roof gutters. The building owners needed a plan to repair and stabilize the sandstone cladding and address the gutter leakage.
