In 1985, Ross Tumulty formed Celtic Demolition as a sole proprietor. His first contracts were for interior demolition of office buildings throughout the Washington, D.C. Metropolitan area. In 1987, the company expanded and brought in David Kavanagh as partner, and incorporated in the state of Virginia.
Celtic Demolition, Inc. has continued to expand since then. It is now one of the largest demolition companies throughout the Washington, D.C., Virginia, and Maryland regions. The company’s projects include razing of buildings, excavation, façade removal, strip-outs, recycling, bridge demolition, and historic preservation.
