Calvert House Apartments Building Envelope Evaluation and Repairs

SK&A’s Repair & Restoration Division conducted a comprehensive condition evaluation of the building exterior for the Calvert House apartment building, a 10-story building located in the Woodley Park neighborhood.  The visible conditions found that affected the integrity of the structure included: spalling and delamination of balcony-slab and exposed-slab edges, peeling of the waterproof membrane on the balconies, and cracked brick mortar joints.  The exterior envelope also experienced chronic leaks and persistent water intrusion.

SK&A prepared a final report detailing the deteriorating conditions in addition to providing repair and preventive maintenance recommendations.  Subsequently, repairs to the balcony and façade were performed, including:  

  • Repair of the spalled and deteriorated concrete on all exposed slab edges, balcony top surfaces and soffits;
  • Application of waterproof membrane on the balcony top surfaces;
  • Application of acrylic coating to the balcony;
  • Replacement of cracked or spalled bricks;
  • Repair of cracked and distressed mortar joints; and
  • Removal and replacement of the existing railings with new glass panel railings.
