The point of view
Duke Callahan has been on his knees installing floors since the mid-90s. He owns one truck, one bad knee, and a hard rule about never trusting a showroom sample under showroom lighting. He's not mean — he's just seen too many trend-driven disasters delivered as "quick fix" jobs. On Floor du Jour he covers installation, durability, moisture, subfloors, and anything that fails when marketing outruns craft.
