Dare to build your own deck and skip our expertise?
You can do it! Follow these simple steps from
Black&Decker Project Center.

Review the design plan before beginning deck construction. Build the deck in several stages, and gather tools and materials for each stage before beginning. Arrange to have a helper for the more difficult stages.

The time it takes to build a deck depends on the size and complexity of the design. A rectangular deck, about 3m × 4.5m, can be completed in two or three weekends.

1. Install a ledger to anchor the deck to the house and to serve as reference for laying out footings. Use batterboards and mason's strings to locate footings, and check for square by measuring diagonals.

2. Pour concrete post footings, and install metal post anchors. Set and brace the posts, attach them to the post anchors, and mark posts to show where beam will be attached.

3. Fasten the beam to the posts. Install the outside joists and header joist, using galvanized nails.

4. Install metal joist hangers on the ledger and header joist, then hang the remaining joists. Most decking patterns require joists that are spaced 16" on center.

5. Lay decking boards, and trim them with a circular saw. If desired for appearance, cover pressure-treated header and outside joists with redwood or cedar facing boards.

6. Build deck stairs. Stairs provide access to the deck and establish traffic patterns.

7. Install a railing around the deck and stairway. A railing adds a decorative touch and may be required on any deck that is more than 24" above the ground.
