When we think of decks, it is safe to say that most of us picture something with steps and railings. But that is just one of many different deck styles. Another type, known as a picture frame deck, is a bit simpler to construct.

A picture frame deck is named that way due to the frame around the infill deck boards. It gives the deck a nice, finished look all the way around.

Step 1: The Tools for the Job

Any good job starts with the right tools for the job. You will need safety glasses, a power mitre or circular saw, a cordless driver, measuring tape, a carpenter square, a cordless drill, exterior-grade construction screws, and other recommended fasteners. 

Step 2: Install Blocking

Start by blocking in the picture frame whenever a deck board runs in the same direction as one of the joists; additional joists or blocking will need to be installed to ensure that the existing substructure has the necessary support. It must also be fastened to the deck boards accordingly. 

Step 3: Cut the Frame

Now it is time to cut out the boards for the frame. You can use a circular or mitre saw to cut the deck boards. For any notching around rail posts, a fine-tooth jig saw is recommended for greater accuracy.
