Cain Contracting served as General Contractor for emergency repairs at the U.S. Department of Commerce Herbert C. Hoover building at 14th and Constitution Avenue, Washington, DC. The project encompassed repairing the lead-coated copper flashing and re-sealing all joints with 20-year sealant, renovating the top perimeter cornice including repairs to the stone cornice, and installing 60 mil EPDM gutter liner.

Refurbishing the existing lead-coated copper flashing included restoring all joints, priming and preparation of contact points, installing new backer rod, installing 20-year silicone sealant, and completely restoring all drains and drain flashing. Approximately 120,000 linear feet of joint restoration was required along with installation of new copper flashing in places where the original panels were missing or damaged.

Cain Contracting prepared a template for replacing seven pieces of the Indiana
limestone cornice. Stone was removed and replaced according to government instructions. In addition, approximately 350 feet of stone was repaired by removing delaminated limestone with chipping hammers and patching using Jahn limestone mortar.

Finally, 3,000 linear feet of 60 mil EPDM gutter liner was installed to the 1.5 million sf building, which encompasses three city blocks and is the 3rd largest Federal Building in the Washington, DC metro area.
