Are you contemplating how to replace deck stair treads to refresh your beloved outdoor living space? Replacing deck stair treads involves selecting durable materials, removing the old treads, and installing new ones securely to enhance both safety and aesthetic appeal.

Installing indoor/outdoor carpet stair treads can also be a great addition to your outdoor space. For a homeowner who values style, safety, and a touch of DIY, revamping your deck stairs can be a gratifying project that transforms the way your multi-story home connects with the outdoors.

How to Remove Deck Stair Treads?   

The first step in transforming your outdoor staircase is to safely remove the old stair treads. Start by prying up the existing treads using a crowbar or hammer, taking care not to damage the stringers (the structural support for the steps). It's important to inspect these stringers for any signs of wear or damage, as they will need to be in good condition to support the new treads.

How to Replace Deck Stair Treads   

Replacing your deck stair treads can be a straightforward process with the right materials and tools. Here's how to achieve a professional-looking finish:

  1. Choose the Right Materials: Opt for materials that withstand the elements and match your home’s style. Composite materials offer durability and minimal maintenance, while natural wood provides a classic look but may require more upkeep.

  2. Measure and Cut: Measure the old treads to get the correct size for the new ones, or adjust the size based on your specific needs. Cut your new treads using a circular saw, ensuring each piece is uniform to avoid a tripping hazard.

  3. Secure the New Treads: Place the new treads on the stringers and secure them with decking screws. Be sure to pre-drill holes to prevent splitting, especially if you are using wood.

  4. Finish for Durability: Apply a weather-resistant finish to wood treads to protect them from moisture and sun damage. For composite treads, a simple cleaning will suffice.

What Do You Use for Treads on Deck Stairs?   

Choosing the right material for your deck stairs is crucial for both safety and design. Composite decking is popular due to its durability and low maintenance, while woods like cedar and teak offer natural beauty and resistance to decay. Whichever material you choose, ensure it provides the required grip and stability to handle frequent outdoor use.

How to Replace a Broken Stair Tread?   

If you encounter a broken tread, it’s essential to address it promptly to maintain the safety of your staircase. To replace a broken stair tread, first remove the broken piece by unscrewing it from the stringers and following the same steps as above to fit a new tread. This not only ensures safety but also maintains the visual appeal of your deck stairs.

How Much Does It Cost to Replace Stair Treads?   

The cost to replace stair treads depends largely on your choice of materials and whether you do the work yourself or hire a professional. Material costs can range from $20 to $50 per tread for common woods and upwards of $50 for composites or premium wood options. If you're DIY-savvy, you'll save on labor costs, making this an affordable project that can have a significant impact on your home's outdoor appeal.


Replacing your deck stair treads not only enhances the beauty and functionality of your outdoor space but also ensures it remains a safe, comfortable area for your family and pets to enjoy. By choosing the right materials and following these steps, you can create an inviting transition from your home to the outdoors.
