Most homes in Phoenix, AZ are built with a concrete subfloor. When glue-down wood flooring is installed, it should be glued down to a wood subfloor and not to the concrete subfloor. Despite the recommendation, many wood floors are glued down to this concrete subfloor, making the glue-down wood floor removal very difficult for a homeowner DIY project. Using hand tool or a jack hammer with a scraper blade will take a lot of hard work, sweat, and time. These images are from a hardwood floor removal job we did in Scottsdale, Arizona.
