Posted on Mon July 10th 2023 by James Speke

Adding a new staircase to your home can enhance its aesthetics and functionality. Even though constructing a staircase sounds like a daunting task, it can be an exciting DIY project if you put in the effort and follow the right steps. In this blog post, we’ll guide you through the step-by-step process of building a new staircase for your home. From calculating the measurements to installing the treads and risers, we’ve got you covered. Let’s dive in!

Step 1: Gather he Required Materials and Tools

Before you can start building your new staircase, make sure you have the necessary materials and tools. You’ll need lumber, screws, nails, wood glue, paint or stain, sandpaper, and a saw among other things. It’s also essential to have measuring tools like a tape measure and a speed square.

Step 2: Determine the Stair Rise and Angle

Calculating the stair rise and angle will help you create a staircase that is safe and comfortable to use. The stair rise is the vertical distance between two consecutive steps, while the angle is the slope of the staircase. You can use an online stair calculator to determine these measurements. Once you know the stair rise and angle, you can cut the stringers, which are the supporting framework for the stairs.

Step 3: Cut the Treads and Risers

The treads are the horizontal part of the stairs that you step on, while the risers are the vertical part that connects the treads. Cut the treads and risers to the appropriate size using a saw. It’s best to use a circular saw or a miter saw to ensure precise cuts. Sand the treads and risers to smooth any rough edges.

Step 4: Assemble the Staircase

Once you have all the pieces of your staircase, it’s time to assemble them. Start by attaching the treads to the stringers using screws or nails. Then, attach the risers to the treads using wood glue and nails. Repeat the process for each step until your staircase is complete.

Step 5: Finish the Staircase

After assembling your staircase, it’s time to finish it up. You can paint or stain the treads and risers to match your home décor. If you’re using natural wood, apply a clear coat to protect the wood from wear and tear. Take the time to sand any rough spots and ensure that the staircase is smooth and safe to use.


Building a new staircase for your home can be a rewarding DIY project if done correctly. The key is to take accurate measurements and follow the necessary steps carefully. By gathering the necessary materials and tools, determining the stair rise and angle, cutting the treads and risers, assembling the staircase, and finishing it up, you can create a beautiful and functional staircase that enhances the value and comfort of your home. Remember to take your time and follow safety precautions, and you’ll have a new staircase that you can be proud of for years to come.
