I'm replacing my existing deck floor that is 1.5 inches thick with a new floor that is only 1 inch thick. This change will result in the sill for the door that leads to the deck being 1/2 inch above the new floor. What's the best way to overcome this problem? Replace the sill? Build the framing up by 1/2 inch? Or something else that this DIYer is just not thinking about?
