Most raised decks require stairs for access to ground level, while railings are necessary for safety. Along with their practical functions, stairs and railings can add architectural interest to your home and deck. When planning stairs, consider whether you want a gradual or steep ascent and adjust ratio of riser to tread accordingly. The stair width can range all the way from the full span of a deck to a minimum 3 ft. wide.
Fasteners & Supports
For all outdoor work you should use rust-resistant hot-dipped galvanized or stainless steel nails. Other fasteners and hardware such as bolts, screws and hinges should also be made from similar corrosion resistant materials.
Footings
Firm foundations for decks and stair posts are critical for durability and safety. Precast concrete footings are available from your building supply dealer, but pouring your own allows greater flexibility and is more likely to provide better long term performance.
Construction Tips for Decks & Stairs
Measure twice, cut once.
Use a plumb bob to check vertical line of posts.
Drill pilot holes when nailing or screwing close to the edge of wood.
Use a 16d nail or wood spacer to ensure equal spacing between boards.
River rock on 6 mm poly under the deck inhibits weed growth.
