Our demo crew worked for 5 days tearing out tile, sheetrock, brick, and the old paper insulation in the attic that had been home to all kinds of rodents and critters since 1955. Three guys from Santa Fe with no protective equipment or power tools made an enormous mess of everything. Most impressively, they disassembled the midcentury fireplace structure with chisels, hammers, and their bare hands. We provided water bottles, bandaids, and filtration masks as needed.
