Install Stair Treads or Risers First: What You Need to Know

install stair treads or risers first

When it comes to stairs, proper installation is crucial for both safety and aesthetics. One of the biggest debates surrounding stair installation is whether to install stair treads or risers first. In this article, we will discuss the reasons why you should consider installing one or the other first, when to do it, and how to install them properly.

Why Install Stair Treads or Risers First?

Understanding Stair Construction

Before we discuss why you should install stair treads or risers first, it’s essential to understand how stairs are constructed. Typical stairs consist of two main parts: treads and risers. The treads are the horizontal part of the stairs, where you place your feet, while the risers are the vertical part between each tread.

Ensuring Safety

One of the most important reasons for installing stair treads or risers first is safety. If not installed correctly, stairs can become unstable, leading to dangerous falls and serious injuries. Installing the risers first can provide added support for the treads, ensuring that they remain stable when in use.

Creating a Clean Look

Another reason to consider installing stair treads or risers first is to create a clean and polished look. By installing one or the other first, you can ensure that the finished product looks sleek and uniform, without any visible gaps or unevenness.

When to Install Stair Treads or Risers First?

Two Risers or More?

Typically, it is recommended to install the riser first when dealing with a set of stairs consisting of two or more risers. By installing the riser first, you can ensure that the tread will sit level on top of it, creating a stable and secure step.

Edge of the Tread

If you are working with pre-fabricated stair treads, it’s often best to install the tread first, as some brands have an overhanging edge. Installing the riser behind the tread in these cases can create a tripping hazard, making it less safe for those using the stairs.

Existing Stair and Hardwood Floor

If you are installing stairs in an existing space, you may need to consider the type of flooring you have. If there is a hardwood floor, it’s best to install the riser first as it can be flush with the hardwood, creating a seamless transition. On the other hand, if you plan on installing hardwood stair treads, you should install them first as they can be more challenging to cut and fit accurately.

How to Install Stair Treads and Risers?

Gather Needed Tools and Materials

Before installing stair treads and risers, you will need a few essential tools and materials, including a saw, measuring tape, adhesive, and nails. It’s also essential to wear protective gear, such as goggles and gloves, when cutting and working with the wood.

Remove Old Stair Treads and Risers

If you are replacing old stair treads and risers, you will need to remove them first. Use a saw to cut through any nails or adhesive holding them in place, making sure to take them off carefully to avoid damaging the existing stairs or stringers.

Install the Riser First

As mentioned earlier, it’s usually best to install the riser first when dealing with multiple risers. Start by measuring and cutting the riser to fit precisely onto the existing staircase. Once cut, apply adhesive to the back of the riser and press it firmly into place. Nails can also be used to secure the riser further.

Can You Install Treads Over Existing Stairs?

Yes, But with Some Considerations

If you have existing stairs that are in good condition, it’s often possible to install new stair treads and risers over them. However, there are a few considerations to keep in mind before doing this.

Installing Treads and Risers Over Existing Stairs

If you plan on installing treads and risers over existing stairs, you will need to ensure that the existing stairs are level and free of any damage or debris. You will also need to measure and cut the new treads and risers to fit the existing stairs precisely. Adhesive and nails can be used to secure them in place.

When to Install Treads and Risers over Existing Stairs?

Installing treads and risers over existing stairs is best suited for situations where the existing stairs are in good condition, and the goal is to improve their appearance. If the existing stairs are damaged or unstable, it’s often better to replace them completely.

Should You Install Tread or Riser First?

Traditional Method: Install Riser First

The traditional method for installing stairs is to install the riser first, followed by the tread. This method provides added support for the tread and helps ensure that the stairs remain stable and safe.

How to Install Tread First?

Installing the tread first can be done but requires more precision when cutting and measuring. It’s essential to ensure that the tread sits level on the stringers and that there are no gaps or unevenness. Adhesive and nails can be used to secure the tread in place, and the riser can then be cut to fit and positioned behind it.

Benefits of Installing Tread First

The primary benefit of installing the tread first is that it allows for more flexibility in creating a design or look. It can also be less time-consuming since you can cut and install all the treads at once, followed by the risers.

In conclusion, whether to install stair treads or risers first depends on the type of staircase you are working with and the desired outcome. By following the guidelines outlined in this article, you can ensure that your stairs are installed correctly, safely, and beautifully.
