This project shows you how to add decorative trim to the edges of a deck.
Stair treads that are 14 inches wide make a graceful transition to the lawn and provide comfortable places for people to sit and relax.
Stairs with 14-inch runs (tread widths) should have rises of between 5-1/2 and 6-1/2 inches.
The wider the treads, the more total run the stringers have to span. When you notch stringers, you weaken them. After the notches are cut out of these 2x12 stringers, about 5-1/2 inches of uncut width is left for strength -- in other words, the stringers are as strong as 2x6s. These stringers have to span a distance of about 9 feet, which is close to the limit for a 2x6 joist. So 2x4 cleats were added for extra strength (Step 7).
Most of a day to install a set of stairs like those shown
Tape measure, circular saw, handsaw, hammer, drill, framing square
Calculating rise and run for a stairway, measuring and cutting with a circular saw, fastening with nails or screws
2x12 for stringers, pavers, sand, and edging for the landing pad surface, decking for the treads, 2x4 toe-kick, lag screws with masonry anchors
Attach the stringers to the toe-kick by toe-fastening with 3-inch deck screws. To add extra strength, attach a 2x4 cleat to the side of each stringer. For each step install the riser board first, then the tread boards. Clamp a scrap 2x4 to the side of an outside stringer to help maintain a consistent 1-1/2-inch overhang. For treads you can use two full-width decking boards and one board rip-cut to a narrower width.
