How to Install a Floating Floor Through a Door Frame

Install the floating floor per the manufacturer’s instructions all the way up to the door opening where a single board will not fit.

Close the door and remove it from the hinges by inserting a screwdriver at the bottom of the hinge and tapping it until the hinge pin pops out. Remove the pins from the other two hinges in the same manner and lift the door out of the way. Although you can install the floating floor with the door still installed, it is extremely cumbersome to do so.

Kneel down inside the door opening and place a floor board up to the side of the door way as far as possible. Turn the board so the finished side faces down so that you don’t damage it.

Lay a hand saw flat on top of the board with the teeth facing toward the wood door jamb. Cut the bottom of the jamb using the saw until you penetrate all the way through the wood. If desired, you can cut the jamb using an oscillating hand tool instead.

Grasp the material at the bottom of the jamb frame and pull it out using your fingers or a screwdriver shaft. The floor board should now slide easily under the jamb.

Repeat the process on the opposite side of the door jamb to cut it as well.

Lay the floor board under the door jamb as much as possible in the final installation location. This varies based on whether the flooring is oriented parallel or perpendicular to the door opening. Mark the ends or sides of the board using a pencil to designate where they require cutting to fit.

Cut the floor boards using a hand saw or a power saw. Insert the tongue end of the floor board into the groove side of an adjoining board and then tap it with a rubber mallet to close any gaps.

Install additional floor boards in the same manner until the entire door opening is complete. Rehang the door on the hinges once you are finished.
