A composite of fused materials, laminate flooring is a durable and usually less expensive alternative to solid hardwood, tile or stone materials. It doesn't take a lot of experience to install laminate flooring yourself, although it's necessary to lay laminate evenly around entrance and closet doors. Undercutting the door by 1 inch and using reducer transitions, which match the laminate you are installing, will create a clean, even edge in and around doorways.
Loosen the screws in the door hinge, using the screwdriver.
Remove the screws; set them aside.
Pull off the door and place on a flat surface or work table.
Measure 1/2 inch up from the bottom of the door, using the tape measure. Mark with a pencil across entire width of door (use a straight edge as necessary).
Undercut the door along this mark, using the power saw. Use sandpaper, as necessary, to refinish. Set the door aside.
Install laminate flooring as indicated on manufacturer's directions, trimming the laminate appropriately to allow the installation of the reducer transition with expansion space (this is the measurement of the width of the reducer transition around the doorway plus 1/4 inch).
Lay the reducer transition in front of the doorway. Install it flush to the edge of the laminate flooring.
Fill in any gaps with floor patch material, following the manufacturer's directions.
Reattach the door to its hinges.
