Designing the first and last stair treads

When you are building a staircase you need to know that you will need to design the last and first treads separately. After this the other ones will just fit into place.

Some of the materials that you will need are:

  • Wooden stair stringers
  • 2×4 wood
  • Screws
  • 3/4 inch plywood

Anchoring the stair stringer

The first important step is to accurately install the stringers.

These are boards cut in an angle, that will help support the entire weight of the stairs. You will need to anchor the stringers so the stairs will not slide where they meet the floor. Starting from the outline where the stairs will start along the bottom of the floor, anchor a 2×4 kick boards to the floor. You will need to cut a notch at the bottom part of the stringer, if it doesn’t have one. Use lead anchors and lag bolts if the floor is made of concrete.

Securing the stringer to the upper floor

Now you will need to attach the stringer to the upper level. You can fix the stringer to the floor joists or you can use the support wall if there is one. Where there is no support wall behind the staircase, you can use a 3/4 inch plywood hanger board to fasten the upper portions of the stairs. You can also use a 2×4 ledger board. You can fix the stringers to it and then the board to the support wall.

Installing the risers

Now it’s time to start on the risers. They need to be installed first because they sit behind the stair treads, and according to the stair plan they should be cut at 7 or 8 inches height. You can nail the risers into the stringers from the front. You can use glue and nail blocks to prevent marks. You can also use metal angle brackets.

Installing the treads

After you have installed the risers, you can secure the treads. You can use adhesive and nails or screws. If you prefer not to have marks visible on the stairs, you should use metal brackets. The stairs treads need to have a nosing that extends at least 3/4 inches out. Place the tread on the first step. Then continue up the stairs until you have reached the top landing. Now all you have to do is install the railings and balusters.
