Sure, building deck stairs can be tricky. But in this story, we'll make it easy by showing you how to estimate step dimensions, layout and cut stair stringers, and assemble the stair parts.

Building a deck makes for a fantastic addition to any home. But it’s not going to be much use without a good set of stairs to get up and down from your primary backyard relaxation spot. The right set of stairs is also a key part of the design, connecting the deck with the rest of your property.

Building stairs might look a little intimidating to the novice DIYer, but they don’t have to be. This project will help guide you through the process, whether you’re doing it for the first time or just in need of a little refresher. Done right, your stairs and deck will last for decades. These DIY steps will also work for replacing an old set of stairs or building new ones. So grab your tools and let’s start building!

When to call a pro

Despite the fact that this article will assist you in understanding the complexities of building deck stairs, there is more to it than simply cutting deck boards and screwing them together. It is imperative that the calculations you do (and we will walk you through them) be precise and accurate, that your craftsmanship matches the same precision, and that you adhere to your local residential stair codes, which can be complicated.

That said, even if you are a seasoned DIYer, you shouldn’t hesitate to hire a professional to construct your deck stairs if you are unsure of your abilities or simply lack the time or resources.
