How To Build Deck Rails

If you’re looking to add some style and safety to your deck, building deck rails is a great way to do it. In this article, we’ll go over the steps you need to take to build your own deck rails.


Before you start building your deck rails, you’ll need to gather some materials. You’ll need:

  • Deck rail posts
  • Deck rail balusters
  • Deck rail brackets
  • Deck rail cap
  • Screws
  • Drill
  • Saw
  • Measuring tape


To get started, you’ll need to figure out the measurements for your deck rails. Measure the length of your deck and divide it by the length of your rail sections. This will give you the number of rail sections you need. If you have stairs, measure the length of the stair railing as well.

Installing Deck Rail Posts

Once you have your measurements, you can start installing the deck rail posts. Place the deck rail brackets on the deck where you want the posts to go. Then, attach the posts to the brackets with screws. Make sure the posts are level and secure.

Attaching Deck Rail Balusters

Next, you’ll need to attach the deck rail balusters. Measure the distance between the posts and cut the balusters to the appropriate length. Then, attach the balusters to the posts with screws. Make sure they are evenly spaced and level.

Deck Rail Cap

Once the balusters are attached, it’s time to add the deck rail cap. Cut the cap to size and attach it to the top of the balusters with screws. Make sure it’s level and secure.

Deck Rail Lighting

If you want to add some extra style to your deck rails, consider adding deck rail lighting. There are many different options available that can add an extra layer of safety and ambiance to your deck.
