DIY Deck Railing

DIY Done Right: Deck Railing

Deck Building

February 27, 2025

For many things in life, safety and style can be mutually exclusive. However, when it comes to your deck, they’re equally important. To give our customers the best of both, The Deck Supply carries kits that make DIY deck railing a snap! Before measuring another baluster, talk to our pros about your design. Discover everything you need to know to get your project done right in this quick read.

Everything You’ll Need

For starters, let’s go over what you’ll need to get your project started. Whether you’re redoing your railing or starting from scratch, there are a few important things to check off your list. Before considering your ideal kit, make sure to get the basics down first.

Structure

Under those beautiful deck boards should be an equally beautiful feat of construction. The underlying structure of your deck will help you determine your joist length and post placement. Proper blocking and support promote a safe and secure installation. By mapping out the design of your structure, our dexperts can help you order the right frame package.

Installation Guides

This is one of the most important, yet often overlooked, elements of a quality DIY deck railing install. To limit headaches during installation, we suggest using an installation template. This takes the guesswork out of hardware and saves time when putting everything together. If you ever get lost in the instruction manual, our resource center has great how-to guides directly from our favorite manufacturers!

Deck Dimensions

When discussing your design with our team, make sure to map out the specific dimensions of the deck. Standard kits with 6’ or 8’ panels don’t measure typical dimensions, but rather the span of a rail section from the middle of the adjoining post to the subsequent post in line. Keeping these intricacies in mind is essential when ordering your ideal kit. That’s why we always recommend ordering with our pros to get the right products the first time.

Tools & Touch-Up Paint

Finally, every DIYer worth their salt should have an adequate array of tools to get the job done. For a truly pro-quality finish, we also recommend stocking up on touch-up paint for those inevitable nicks and scratches. Whether you’re borrowing them from a buddy or looking for an excuse to visit the hardware store, these are the basic tools that should be in any weekend warrior’s arsenal for easy installation:

  • Circular/Band Saw
  • Rubber Mallet
  • Screw Gun/Drill Driver
  • Pencil/Marker
  • Tape Measure
  • Clamps
