Open the door. Sweep the area under the door and around each side of the doorframe. Ensure no debris larger than dust sits on the subfloor surrounding the work area.
Lay a piece of laminate floor on the subfloor with the finished side of the flooring facing down.
Slide the piece of laminate flooring against the wall molding secured to one doorframe leg – both if the piece is long enough. Push down to hold it in place.
Set the flat blade of a trim saw on the unfinished side of the laminate flooring. Use a back and forth motion to saw through the pieces of molding. Repeat the cutting process on the other leg of the doorframe.
Move the piece of laminate flooring to the other side of the wall. Realign the flooring. Cut the molding from the other side of the doorframe. Continue until all molding sits above the piece of flooring. Cut a straight line across the centerpiece of the doorframe. Ensure the doorframe cut aligns with the molding cuts on either side of the wall.
Sweep the sawdust from the area before installing the laminate flooring.
