Deck Height (compared to threshold)
We are having a deck built and a question of deck height, in relation to the sliding door threshold which leads to the deck has arisen. What is the recommended drop in height, if there is a recommendation, for the deck surface as compared to the threshold one is walking through to reach the deck? Our builder recommended that the deck be a minimum of 3 to 4 inches lower than the threshold to protect the door from rain and snow. Your thoughts, comments, experiences are appreciated. Thanks.
