How to Build a Rectangular Deck

Step 4: Square the Frame.

Place a 2"x6" support board on top of each row of Dek-Block® piers. Attach the 2"x6" end boards to support boards using two 2 1/2" deck screws at each connection. Using a level as a guide, ensure that both end boards and both support boards are level.

NOTE: The end boards will extend past the support boards up to the house. Leave a 1/8" to 1/2" gap between the end board and the house. This is not shown on our standard plans.

Next, measure the diagonal distance from opposite corners. Adjust the outside support boards and Dek-Block® piers until the diagonal distance between opposite corners is EQUAL.

After the deck is square and level in all four directions, attach the 2"x6" support boards to the 4"x4" posts using two 2 1/2" deck screws. At an angle from each side (toe-screw).
