A DIY staircase makeover can be fun, starting out. New stairs can change how your home looks and feels, and this guide can help you achieve the effect you're going for, whether you're building a new staircase or replacing an old one. It will teach you what you need to know and give you the level of confidence that you need to complete the project. We will start with the first step, understanding what you're trying to do here, and guide you all the way to the last step (where you take a proper look at your hard work).

Let's begin.

Preparing for Your DIY Stair Project

You will need measuring tapes, levels, saws, and hammers. Each tool is important for making precise cuts and strong connections to get a professional result.

When it comes to materials, choose high-quality lumber for your stair treads, risers, and stringers. These parts need to hold up under daily foot traffic, so they must be durable. Also, remember to get supplies like construction adhesive, screws, and nails that are made for stair building. We'll create a checklist for you. Just keep reading.

The Basics of Stair Installation

Let's start from the beginning.

Every staircase has steps. Each step has a stair tread, which is the part you step on, and a stair riser, which is the vertical part that leads to the next tread. The top step is called the landing tread. It connects the staircase to the upper floor. Knowing how these parts work together is important for a safe and useful staircase.

There are building codes for stairs, and any staircase that's built to code is one that will stay safe and strong until the entire home crumbles. Such codes specify the width of the stairs, the height of the risers, the depth of the treads, and the rules for handrails. Before you start your project, check your local building codes. These rules can differ based on where you live.

Essential Tools and Materials Checklist

Having the right tools and materials ready will help your DIY stair installation go smoothly. Here is a list of what you need:

Tools:

  • Measuring tape
  • Level
  • Circular saw
  • Hand saw
  • Hammer
  • Drill
  • Stair gauges
  • Safety glasses

Materials:

  • Lumber for stair treads, risers, and stringers
  • Construction adhesive
  • Screws and nails
  • Wood filler
  • Paint or stain
  • Polyurethane

This is more of a general checklist, things that 8 out of 10 staircase projects need. If you have a unique vision for your creation, you might need to include tools like a lathe, a chisel, etc.

Planning and Designing Your Stairs

Next up, your vision for your staircase. You need to put it on pen and paper.

Even if you don't have the expertise you need to properly paper your vision, you can describe what you want to an expert. There are more than a few on freelance services like Upwork and Fiverr. What you want to create will determine how hard your project is.

Measuring Your Space Accurately

Accurate measurements are very important for a good stair installation. Start by finding the total rise (that's the vertical distance from the finished floor of the lower level to the finished floor of the upper level). Simply divide that value by the specified height of each individual step's rise (from building codes) to know how many step risers your staircase will need. If you get a decimal or remainder after the division round up to the next whole number.

Next, measure the total run. This is the horizontal distance the staircase will cover. Use the building codes and what you find comfortable to find the best riser height and tread length. Make sure the landing tread tops out at the same height as the tops of the stringer lines.

Choosing the Right Type of Stairs for Your Home

There are many things to consider when choosing the right stairs. Where will the stairs go? What are they for? Will they fit the style of your home? Pressure-treated lumber or some other composite material is best for outside areas, for instance. They can tolerate the weather well.

If you have a concrete slab, the stairs can even be built on top of it. For speed, it wouldn’t hurt to use a precast concrete staircase too. Home Depot has a lot to offer in regards to stair parts and materials.

Step-by-Step Guide to Stair Installation

No further ado. Let's begin.

Step 1: Setting Up the Foundation

Start by making sure that the ground where your stairs will go is level and sturdy. For deck stairs, you should create a strong base with concrete footings or piers. If you are using a concrete slab, make sure it has no cracks or flaws.

Step 2: Cutting and Installing Stringers

Stringers, running on each side of stairs, are what provide the framework for the tread of every staircase. Start by marking the stringers based on your earlier measurements.

Then, use a circular saw to carefully cut along the marked lines. This will create notches for attaching treads and risers. Make sure your cuts are clean and precise to keep the stringers strong.

Next, attach the stringers to the landing platform or the upper floor framing. Use the right hardware, like joist hangers and structural screws. Check with a level to make sure the stringers are straight and well-aligned. This will help you create a safe and straight staircase.

Step 3: Attaching the Treads and Risers

After the stringers are ready, it’s time to install stair treads and risers. This allows your staircase to have its shape. Begin by putting a line of construction adhesive on top of each stringer notch. Then, set the treads in place.

Use a hammer and finish nails to attach the treads to the stringers. Make sure the stringers and the way the webs have been cut and shimmed correspond exactly. And of course, add the risers beneath each tread, after the treads are in place. Secure them with construction adhesive and nails.

If you notice any nail holes, fix them up by using the wood filler so that it’s smooth. Keep sanding and painting, only stopping when the filler is dry fully.

Step 4: Finishing Touches (Sealing and Staining)

Sealing and staining are very important in DIY stair installation. They help protect your stairs and make them look great. Once the steps are secure, you should improve the wood with coats of polyurethane. Make sure the treads and risers are even before you apply the finish. Use a brush or a rag to spread the sealant evenly. This will cover nail holes and seams. You can add stain to give more color and match your design. Let each coat dry completely before putting on another for the best look.

Now, take a good long look at what you’ve done. Congratulations!

Installing stairs by yourself can be a fun project if you do it right. However, with how complicated it can be, especially if you have more unique requirements, that "if" is a big one. In construction, the little mistakes add up. That's why we'd advise hiring professionals instead. Just observe how professional work. You can do it yourself next time. This guide is long and detailed to the best of our ability, but it isn't enough.

Speaking of professionals, you'll find no one better than Master of Wood Floors to bring your vision into reality. Just reach out to us whenever you're ready.
