In this article we will walk you through the steps of designing and building a railing that not only serves its purpose but adds personality and warmth to your street.

Let’s explore how the perfect railing can make your deck a place especially that you can enjoy.

Step-by-Step Guide to Build Deck Railing

Although it is most often associated with providing a safety feature for extending a deck, deck railing does much more than that.

Here are the step-by-step instructions of building deck railing, covering all the major points from planning and material selection to installation and finishing.

Step 1: Planning Your Deck Railing

Planning Your Deck Railing

A detailed plan of the requirements must be obtained before actual construction work commences. Consider:

Building Codes: Check to make sure the height of your railing and the space required between them is met in your building codes. The ideal height should be anywhere between 36 and 42 inches with a maximum of 4 inches in between the balusters.

Make and Style: You should consider what kind of makes would best complement your deck, especially your composite decking. This could be from the traditional wood railings, metal railings, cable railings, or glass panels.

Material to be used for the Railing: Select one which is sturdy and able to endure extreme weather conditions. Examples of these materials are pressure-treated wood, composite, or metal.

Step 2: Gathering Materials and Tools

Once you have a plan, gather the necessary materials and tools. Here’s what you’ll need:

Materials

  • Railing posts
  • Top and bottom rails
  • Balusters or spindles
  • Post caps
  • Deck screws or bolts
  • Wood glue (optional)
  • Concrete mix (if installing posts in concrete)
  • Paint or stain (if using wood)

Tools

  • Tape measure
  • Level or Clamps
  • Drill and bits
  • Circular saw or miter saw
  • Carpenter’s square
  • Post-hole digger (if setting posts in the ground)
  • Paintbrush or sprayer

Step 3: Installing the Railing Posts

The first step in building your deck railing is to install the railing posts. These are the vertical supports that anchor the entire railing system.

Mark Post Locations: Measure and mark the locations for your railing posts, typically at the corners of the deck and intervals along the perimeter (usually no more than 6 feet apart).

Prepare the Posts: Cut your posts to the desired height, adding an extra 6 inches if they will be set in concrete. If mounting posts on the deck surface cut them to the exact height needed.

Step 4: Mounting Posts on the Deck Surface (if applicable)

Dig post holes at least 12 inches deep and 8 inches in diameter and then place the post in the hole. Align the post with the mark on the deck surface. Drill pilot holes and secure the post using deck screws or bolts. Pour in the concrete mix, ensuring the post is level and plumb. Allow the concrete to cure for at least 24 hours.

Step 5: Attaching the Top and Bottom Rails

The rails are those horizontal parts of your deck railing that join the posts to one another and support the balusters.

Measure and Cut Rails: Measure the distance between every pair of posts, followed by cutting the top and bottom rails to length.

Attach Bottom Rail: Place the bottom rail as desired in height, usually 2 to 4 inches off the deck surface, holding it with clamps. Make pilot holes and then screw the rail to the posts.

Attach Top Rail: Fasten the top rail on top of the posts, ensuring it is level concerning the bottom rail, screwing it into place.

Step 6: Installing Balusters or Spindles

The vertical members that fill the space between top and bottom rails are commonly called balusters or spindles.

Measure and Cut Balusters: Measure the height from top to bottom rail, then cut the balusters to the appropriate length.

Mark Baluster Spacing: Determine the baluster spacing, so that they are no farther apart than 4 inches; then mark their position on both top and bottom rails.

Attach Balusters: From one end, across the railing section, install each baluster with screws to the top and bottom rails. A level will help you make sure each baluster is plumb before tightening. For added protection from open areas, and a more finished appearance, consider using wood glue in addition to screws.

Step 7: Adding Post Caps and Finishing Touches

Post caps provide decor for your railing and keep the tops of posts from weathering. Choose post caps to match your railing style and secure to the tops of posts with adhesive or screws. Smooth all edges and surfaces as necessary.

Apply some form of weather-resistant stain or paint to the wood for the railing so as not to suffer through the element. 

Readjust where needed, tightening screws or reapplying paint or finish. Allow the finish to dry before using the deck.
