Slanting wood floor
Q: My living room is about 12′ x 13′ with a slanting wood floor that varies over an inch from one side of the room to the next. Is there anyway of levelling this without destroying my downstairs neighbours ceiling and without spending gobs of money? I am also interested in laying down some sort of soundproofing underlayment such as cork which I would then top with a glueless wood flooring. Is all of this too heavy and too difficult for such an old building apartment?
A: Structural issues such as unlevelled floors are best fixed from the structure (joists). If that is not an option, you could consider this: I have seen these square tiles with delta floor backing which interlock and are intended to be used as a sub floor material. They are made of either chip board or OSB with the heavy plastic, dimpled backing. You can use provided shims to level these squares. I have seen them at Home Depot. It is very important when installing a floating floor that the sub floor be near dead flat. Humps in the floor are especially insurmountable, while dips can be filled with paper or these sub floor squares I mention, over the entire existing floor. Do you know the product I am referring too?
