Deck 10: Installing the Deck Railing Instructions

  • Installing the Deck Railing

    This is the final tutorial on the series of building you deck. If you have followed the steps that we have outlined carefully and safely you should have no problem putting in a railing that is both attractive and secure. Deck railings are important to both the safety and the aesthetic appearance of your deck. In other words, a railing is the perfect blend of “strength and beauty”. A deck railing must be built to comply with your local code requirements. For instance, a deck rail should be at least 36" tall and should not have any gaps that are greater than 4".

  • Overview

    There are four major steps you will follow to install the deck railing. First, refer to your deck plans to determine the location of the railing posts, and mark the location of each post using a square. Then, squarely cut all the railing posts to length. Once you have secured the posts to the joists you can finally install the balusters and the cap rail.

  • Mark Post Location

    Refer to your deck plans to determine the location of the railing posts. Along the outer joists and joist header, mark the location of each post using a square. Mark both edges of each post, which should be 4" apart.

  • Make Necessary Cut to Decking

    If your deck surface hangs the edge of the deck framing, use a handsaw or reciprocating saw to cut notches in the deck so that the posts can fit squarely against the deck framing.

  • Determine the Hieght

    Determine the correct height of the railing posts. Assuming the finished height is 36", you will need to add the thickness of the deck surface (usually 1-1/2") and the height of the joists (usually 5-1/2"). Squarely cut all the railing posts to length using a miter saw.

  • Install the Railing Posts

    Install the railing posts using 2 lag bolts each. Use a socket wrench to drive them into place.

  • Install the Upper Railing Base

    Using 2x4 lumber, measure and cut the upper railing base. Install the upper railing base to the top of the posts using 2 screws per post. When installing the balusters, you can run them all the way down to the deck frame or you can install a lower railing the supports the bottoms of the balusters, the choice is yours.

  • Calculate the Number of Balusters

    Measure the distance between each set of posts. Calculate the number of balusters you will need to maintain an equal distance between all balusters. Remember the balusters should be no more than 4" apart. Mark the location of each baluster on the top railing and lower railing or joist.

  • Install the Balusters

    Measure and cut the balusters to length. For an attractive appearance, cut the bottoms of the balusters at a 45-degree angle. Using 2 screws at the top and 2 screws at the bottom, install the balusters.

  • Install the Cap

    To top off your railing project, install a 2x6 cap on top of the upper railing base and posts. Miter the corners at 45-degree angles. Use screws to screw the railing cap to the 2x4 upper railing base.
