The installation of aluminum deck railing is a rewarding project that elevates the safety and aesthetics of your outdoor space. While hiring a professional is an option, some homeowners prefer to undertake the installation themselves to save on costs and achieve a sense of accomplishment. In this blog, we will provide a step-by-step guide for homeowners to successfully install aluminum deck railing and enjoy the process of creating a secure and visually appealing deck.

  • Gather Necessary Tools and Materials:

Before beginning the installation, gather all the required tools and materials, including the aluminum railing kit, measuring tape, level, drill, screws, and post anchors. Ensure you have the correct measurements of your deck’s perimeter and determine the number of railing sections needed.

  • Mark Post Locations:

Use a measuring tape and level to mark the locations for the railing posts along the deck’s perimeter. Ensure the spacing between the posts is in compliance with local building codes. If necessary, use post anchors to secure the posts to the deck surface.

  • Install Bottom Rail:

Start the installation by attaching the bottom rail to the posts. Use the provided screws to secure the bottom rail securely in place. Check that the bottom rail is level and aligned with the marked post locations.

  • Attach Balusters:

With the bottom rail in place, insert the balusters into the pre-drilled holes on the bottom rail. Depending on the chosen design, balusters can be straight or curved, or even glass panels.

  • Secure Top Rail:

Once the balusters are in place, attach the top rail to the posts and secure it using screws. Double-check the alignment and level of the top rail.

  • Add Accessories:

If desired, add any accessories, such as post caps or decorative elements, to enhance the appearance of your aluminum deck railing.

  • Test and Adjust:

After completing the installation, thoroughly inspect the railing for stability and security. Ensure there are no loose screws or wobbly posts. Make any necessary adjustments to ensure the railing is secure.
