I'm under contract to purchase a new-construction condominium. The developer has installed maple hardwood floors in the living area. The developer tells me that the floors have been installed as part of a relatively new technology called a "floating floor", which is supposed to dramatically cut down on noise transference. All sounds fine to me. However, I inspected the floors recently, and it seems to me that they are slightly warped (buckling) around the floorboards. In addition, they "creak" and bend ever-slightly when I put my weight on them right at the point where the flooring meets the wall-board. In the center of the floor, they're fine and look great. The developer tells me this is the way this new floating floor works. I'm looking to the message board for some commentary/help. Should they be doing this?
