10 Step-by-step Guidelines on How to Build Cascading Deck Stairs

Step 1: Measure the Area

Measure the area where you’d like to install your cascading deck stairs. Make sure you have enough space for them, including any curves or levels that you plan to include. If you’re working with an existing flat surface, calculate how much incline the stairs need to provide. It’s important to ensure that the stairs are stable and secure.

Step 2: Design the Stairs

Using your measurements, sketch out the design of your cascading deck stairs. Draw a rough plan of the shape and size you would like your stairs to be, as well as any curves or levels that you plan to include.

If you need help designing the stairs, there are plenty of helpful online tutorials and diagrams. It’s important to be as precise as possible so your stairs turn out the way you want them.

Step 3: Set Out the Posts

Once you’ve determined where your posts will go, use a post-hole digger to dig out the holes for them and then set the posts in place. Make sure that each post is level before securing it with concrete.

This will ensure that the stairs are securely in place. It is also important to make sure that the posts are spaced evenly and securely. It’s best if you use pressure-treated wood to build the posts.

Step 4: Calculate the Rise and Run of Each Step

The rise is how high each step is, while the run is how long it will be. An appropriate ratio for these two measurements is 2:1; that means that each step should be twice as long as it is high.

If you’re working with an existing flat surface, the rise may vary more than normal. It’s important to make sure that the stairs are safe and comfortable for anyone who uses them.

Step 5: Cut Deck Boards or Lumber to Size

Using a Circular Saw

Using a circular saw, cut the boards or lumber you’ve purchased for your steps to fit. Make sure to measure out the exact length and width needed for each piece before cutting. This will ensure that your stairs are precise and even. If you don’t have a circular saw, you can also use a handsaw or miter saw.

Step 6: Secure Steps Down with Nails

Line up the pieces of lumber and securely fasten them with nails. Make sure to use the appropriate size and type of nail so that your stairs stay in place. This is also a good time to double-check that the rise and run are correct. It’s important to ensure that there is no wobbling or instability in the steps. If there is, then you need to make adjustments.

Step 7: Seal the Decking

Once all the pieces are secured down, it’s important to seal them with a water-repellent sealant. This will help protect your deck against moisture damage while also giving it a finished look. It’s best to use a sealant that is specifically designed for outdoor wood surfaces. This will ensure that your deck is properly protected. If you’re using pre-treated lumber, you may not need to use a sealant.

Step 8: Install Handrails and Balusters

For added safety, you’ll want to add handrails on both sides of the stairs. You can either buy premade ones or make them yourself out of wood or metal posts and balusters. Make sure they are securely fastened in place so that they don’t wobble or move when someone is using them. If you’re using metal posts, you may need to use a drill to secure them in place. But if you’re using wooden posts, then simply use screws and nails.

Step 9: Add Finishing Touches

Any Outdoor Accessories Such as Planter

Add any additional decorative touches you’d like to have, such as lights or trim. You can also paint or stain the stairs for a customized look. This is also a great time to add any outdoor accessories, such as planters or furniture.

Make sure everything is securely fastened in place so it doesn’t move or wobble when people are using the stairs. It’s important to remember that these steps will be used on a regular basis, so they need to be safe and secure.

Step 10: Enjoy Your Cascading Deck Stairs!

You’ve done it! Now it’s time to enjoy your new cascading deck stairs and all they offer you in terms of convenience and style. Don’t forget to take pictures before inviting friends over so that everyone can appreciate your handiwork. 

Always refer to safety guides and building codes when constructing any kind of decking or stairs, as well as follow safe practices. However, with the right materials and some patience, you can create an impressive and stylish set of stairs that will last for many years to come!

Follow these steps on how to build cascading deck stairs and you’ll be able to build beautiful cascading deck stairs in no time at all. With a little patience and effort, you can create an outdoor area that you and your family can enjoy for years to come.

Do You Need to Use Professionals?

If you’re not confident in your DIY skills, it’s best to get professional help. A deck specialist can ensure that your stairs are built safely and to code. They’ll also be able to give you advice on what materials would work best for your specific project. Professional installation is often worth the cost as it will ensure that your cascading deck stairs are secure and safe for use.
