A summary of the procedure

●    calculating the increase and fall

How to build deck stairs? Make a note of the length and breadth of your stairwell. All dimensions for the height and width of the stairs, the number of steps you want to create, the areas for the concrete base, and the depth of the steps must be recorded.

●    Construct a concrete foundation

Using a tamper, compress the dirt and dig 2 to 4 inches below the surface. Then pour concrete till it hits ground level, smoothing it out with a trowel and levelling it. Allow 24 to 48 hours for the cement to settle.

●    Remove the stringers

Build the side of the stairs using the frame square. Cut the timber boards using a circular saw first, then finish with a hand saw. To make more stringers, continue the cycle.

●    Attach stringers to the deck and the footer

Place the bottom ends of the stringers on the concrete pad and the other against the deck’s face. Check the location of the stringers with the level before attaching them with angle brackets and screws.

●    Cut and secure treads

How to build platform steps for a deck? The stair treads are 1 inch on both sides, where they overlap the stringers. One of the treads should be pushed against the backside and centre of the stringer, and two 3 inch deck screws should reassemble the railings. Cut two 4×4 post sections to a length of 30”. The lowest railing posts will be made of this so that the rail posts about firmly against stringers, a tiny part of the bottom front tread will need to be carved out. Place pegs at the foot of the stringers and indicates the tread that will be removed. With a handsaw, cut a notch in the tread.

Use 4” deck screws to secure posts to stringers, making sure they are plumb. As illustrated in the figure, cut lengths of 2×4 railings to bridge the space between the bottom posts and the existing deck railing. Use 3” deck screws to attach the rails to the posts, ensuring that the slope matches the steps. Cut comparable pieces that will be used as the foundation.
