Remove the existing kitchen flooring. Score laminate and vinyl flooring with a utility knife and pull it up. For tile floors, remove the grout with a circular saw and remove the tiles with a pry bar.
Place the new hardwood floor boards in the kitchen. Let them sit for three or four days. The wood will expand or contract depending on the climate of your kitchen.
Set a hardwood floor board next to the dishwasher. Measure and mark the amount you will need to cut out to fit around the dishwasher.
Make the cuts using a jigsaw. Set the board along the dishwasher to make sure it fits nicely.
Nail the cut piece in place along the dishwasher edge. Continue nailing in the hardwood boards, staggering them across the kitchen floor.
Mark the location where the shorter boards need to be cut. Make the cuts with a jigsaw and install with the power nailer.
