Trex Decking End Caps: How to Hide Deck Board Ends Without End Caps

If you’re planning a Trex deck, one of the details you might be wondering about is how to finish off the ends of your deck boards. While some decking manufacturers offer end caps as a solution, Trex does not manufacture end caps for their decking products.

This can lead homeowners to search for alternatives that not only enhance the appearance of the deck but also protect it from the elements.

So, what’s the best way to conceal the cut ends of Trex decking? Let’s explore two proven techniques: picture framing your deck and covering the edges with fascia boards.

Why Trex Doesn’t Offer End Caps

Trex decking is designed to be low-maintenance, highly durable, and resistant to moisture, fading, and stains. End caps, typically found in hollow-core or scalloped composite decking, are used to seal the exposed ends of hollow boards to keep moisture and debris out.

However, since Trex decking boards are solid, there is no need for end caps. Instead, you can achieve a clean, professional finish through alternative methods that complement Trex’s high-quality design.

The Trex Enhance line is a scalloped deck board as shown below. Many find the ends of scalloped boards not as visually appealing as the solid core boards.

Picture Framing Your Deck

One of the best ways to hide the ends of your Trex deck boards is by picture framing your deck. This technique involves installing a border of deck boards around the perimeter of your deck and stairs. By using a contrasting or matching color for the frame, you create a polished look that seamlessly conceals the ends of the boards.

Pro Tip: If you are using the grooved deck boards for hidden deck fasteners, make sure you order some square edge boards for the picture frame. Having grooved boards on your picture frame border looks less visually attractive than the square edge.

Benefits of Picture Framing:

  • Aesthetic Appeal: Picture framing adds a finished look that elevates your deck’s overall appearance.
  • Durability: It helps protect the edges of your deck from foot traffic and wear.
  • Customization: You can get creative by choosing a different color or style of Trex decking for the picture frame to make your deck stand out even more.


Picture framing is also a common method used on stairs to conceal the ends of the deck boards while providing a more robust, refined edge for the step.

Covering Deck Edges with Fascia Boards

Another excellent way to hide the ends of Trex deck boards is by covering them with fascia boards. Fascia boards are thin boards that run along the sides of your deck, hiding the ends of your deck boards while giving your deck a crisp, finished edge. Trex offers fascia boards specifically designed to match their decking, so you can achieve a consistent, seamless look.

Benefits of Fascia Boards:

  • Protective Layer: Fascia boards add a layer of protection to the ends of your deck boards, helping prevent moisture from penetrating the deck structure.
  • Clean, Seamless Finish: The smooth surface of fascia boards gives your deck a sleek, modern look, free from exposed board ends.
  • Easy Installation: Fascia boards are simple to install and offer a straightforward solution to finish your deck edges.


Choosing the Right Approach for Your Deck

Whether you opt for picture framing or fascia boards, both options allow you to conceal the ends of your Trex deck boards in a way that maintains the beauty and durability of your deck. Picture framing offers a more detailed and design-forward approach, while fascia boards provide a minimalist, seamless finish. Either way, you’ll be able to achieve a professional look that hides the cut ends and enhances the overall appearance of your outdoor space.

If you’re planning a new Trex deck or looking to upgrade your current one, keep in mind that these methods will offer a better, more reliable finish than searching for non-existent Trex end caps. With the right finishing touches, your deck can look flawless for years to come.
