Things to Consider

Know Your Code!

The first consideration in choosing deck railing is always safety. Before starting any deck project, contact your local building department for any and all applicable code requirements. These vary from state to state and even among municipalities, but typically are as follows:

  • Baluster spacing -The opening between balusters should be less than four inches.
  • Railing height - Required railing height can also vary from city to city. The most common minimum height requirements are 36 or 42 inches from the deck surface to the top of the railing. Contact your local building department for specifications regarding your project. Many municipalities updated their requirements in 2009 and 2010.

Budget

In order to accommodate many budgets, DecksDirect.com offers a wide variety of rail systems. If you have an idea what you’d like to spend per lineal foot of rail, either refer to our railing manufacturers page in this guide or contact one of our railing experts to discuss which material or manufacturer is best for your needs.

Time Frame

DecksDirect is the largest stocking dealer of deck railing. However, when offering a large variety of options, not all railing systems can be stocked at our warehouse. If your project deadline is fast approaching, it is best to choose from items that are in stock and can be shipped quickly to avoid disappointment. Look for shipping details like “Quick Ship” and “Special Order” on the specific product pages.

House's style/architecture

In our opinion, the railing is THE most important choice you will make when planning your deck. It will be noticed from near and far, for better or worse. The size, color and style of railing can have a dramatic impact on the look and feel of your deck, and can help it to blend with the rest of your home and yard. For the most aesthetic appeal, the railing should complement the other details of your home by being in proportion to them.

Experience level

The seasoned handyman will be able to tackle any system without difficulty and will not shy away from a system which requires assembly of individual top and bottom rail components, balusters, and connectors. On the other hand, a homeowner new to this type of project might have more success installing prefabricated panels or using a system that has predetermined baluster sizes, angles and locations with pre-installed baluster connectors.

Location (coastal or inland)

Exposure to saltwater and salty air can damage a number of rail systems. If you are within a mile of the coast, contact us to find out which systems are approved for the conditions in your area.

Exposure to sun/elements

Environmental factors can play a role in your railing’s appearance and function. Choosing a black metal rail is not recommended for a deck that will be in full sun in a hot climate. A glass railing within reach of lawn sprinklers might look perpetually spotty, and glass balusters can magnify the sun’s intensity (increasing the temperature on the deck surface) while cutting down on airflow.

Color preference

Not all rail styles are available in all colors, so keep that in mind if color is your most important feature. For example, if white is the desired color, it is good to start with styles offered in white. Some systems have components that can be mixed and matched to achieve a custom look, and you may consider choosing a color or multiple colors to match or contrast with features on or around the home. Also keep in mind that the darker the color of the railing, the clearer the view through the railing will be.

All about the view - or lack of it.

Railing not only controls your view from the deck, it also determines what your neighbors can see. Wide balusters and railing provide more privacy for a deck with a hot tub, whereas glass panels and cable railing invite views from all perspectives. As stated in the color section, choosing darker infill allows for easier viewing through a rail section to the scenery beyond the deck.

Ideal post mounting application for the project

To maximize the available space on the deck surface, fascia mounting is a great option. Not all systems offer this type of post, so the traditional method of mounting to a horizontal surface might be required.

Additional blocking or structure

To ensure a stable connection between each post and frame, a solid block is needed. If the framing does not already have enough structure, added blocking is necessary to enhance stability.

Maintenance Matters

How much time do you really want to spend maintaining the look of your deck and its railing? Traditional wood rails are quite time- and labor-intensive to maintain, so choosing a different material can free up lots of time to enjoy the deck! Glass panels or balusters may require treatment to minimize spotting, but materials like metal and composite are virtually maintenance free.

Available Accessories

Are you planning a railing with a simple, straightforward layout? Or is complex and embellished what you need? Each system has its own bracketry to accommodate angles and stairs, and some offer add-on enhancements such as cap rails for creating a unique look for your specific project.


Railing Materials

Aluminum Railing

Lightweight and durable, aluminum railing resists rust and corrosion—making it virtually maintenance-free for the life of the product. Aluminum is available in several colors and baluster shapes. DecksDirect offers aluminum railing systems from Westbury, Fortress, Deckorators, Afco, Solutions, and more.

  • Pros: clean look, ease of install, can be used between any newel posts
  • Cons:modern look doesn’t mesh with all architecture

Cable Railing

Constructed of 316 stainless steel, cables are available in 3/16” and 1/4” diameters but are most commonly used in 1/8” diameter. Nineteen thin cables are wound together to produce one durable and attractive cable. DecksDirect carries a variety of horizontal and vertical cable, as well as the opportunity to do a fully-custom system with Feeney DesignRail®.

  • Pros: unobstructed views, modern design, easy to install, low maintenance, customizable
  • Cons: more expensive than wood, not child-friendly, may not meet code in certain areas

Cap-Stock Composite Railing

A wood-alternative material, that contains plastic, recycled material and wood fibers. Cap-stock is the result of co-extruding composite material with an exterior shell, typically made of PVC. The inner substance provides durability; the outer coating is an attractive finish available in several colors. Find options from Deckorators, TimberTech, Trex, and others.

  • Pros: durable finish, can’t rust, can look similar to wood, high color retention, resists stains & fading
  • Cons: bulky, can appear heavy, looks similar to wood, moderately strong, labor-intensive install

Glass Railing

Allowing clear, unobstructed views, glass railings are tempered for safety. Some manufacturers add etched designs, lighting options and a choice of color tints. For minimal upkeep, glass can be treated to reduce water spotting. DecksDirect offers glass balusters or panels and compatible rails from several outstanding manufacturers.

  • Pros: Unobstructed views, modern design
  • Cons: may require frequent cleaning, can be costly to ship, can increase temperature on deck surface

Steel Railing

Steel railing is a heavy-duty option that is great for replicating the look of wrought iron. DecksDirect offers the complete Fortress FE26 Railing System, which features pre-welded panels that are amazingly strong and durable, without the hassle of separate parts and pieces.

  • Pros: strength, ease of install, panelized versions available, adjustable stairs panels
  • Cons: possibility of rust, heavy to work with

Vinyl Railing

For low-cost, low-maintenance, no-frills railing, vinyl is an obvious choice. Lightweight and easy to install, its non-porous surface won’t require painting or staining, though from a distance it can resemble painted wood. At this time, DecksDirect offers vinyl systems from Durables and Fairway.

  • Pros: price friendly, low maintenance, lightweight
  • Cons: limited color options, can appear cheap, can become brittle in cold weather

Wood Railing

Traditional wood railings are still a popular choice, and the reasons are obvious: the stately, professional look is classic, elegant and economic. However, the very features that make wood so attractive also lead to time-consuming maintenance. Wood railings tend to damage more easily and require significantly more time to stain or paint on an annual basis. At this time, DecksDirect does not offer wood railings, though there are a number of aluminum and steel options that can be installed between wood newel posts.

  • Pros: natural look, inexpensive, can be painted or stained to match decking
  • Cons: high maintenance, susceptible to decay, warping and bowing, obstructed views

Railing Purchasing Checklist

It's all in the details. When you envision yourself on a new deck, you’re probably thinking about the moments you’ll spend with friends and family, socializing and relaxing. You’re not pondering the individual elements of construction like balusters. And yet, along with the decking itself, balusters provide the details that outline every moment there.

If you’re about to build a new deck, or feel like upgrading the one you have now, then this baluster guide is just for you. From stately wood to clear glass, here’s a quick introduction to the styles and choices in balusters today: and why they matter.

For additional assistance or advice, take advantage of the experts at DecksDirect by calling 1-888-824-5316. We're in the office from 7 a.m. to 8 p.m. CST Monday - Thursday, 7 a.m. to 5:30 p.m. CST Friday, and 11:30a.m. to 8 p.m. CST Sunday.

For best results on your project, we recommend reading through the topics in order.


Measure

Measure twice, order once! Make sure you have accurate deck measurements from which to create your materials list. Jot these numbers down and make a quick sketch of the space. Don’t worry if it’s not a professional drawing, a simple sketch will help when deciding what materials are needed.

Choose Railing

DecksDirect offers a variety of railing choices, read our Things to Consider section in this railing guide for tips on choosing the perfect railing.

Plan

Plan your newel post layout according to the rail lengths available in your selected rail system. (Be sure to look at actual lengths of rail sections. Because some systems use “on center” measurements, 6' and 8' doesn’t always mean 72" and 96".) Then, add these posts and rail sections to your sketch.

Choose Posts

Are the posts for your selected system structural or sleeves?

If structural, do you have bolts for attaching to the deck surface? Consider GRK Rugged Structural Screws.

If they are sleeves, do you have an attachment method for your wood interior posts? The Titan Wood Post Anchor is a handy, sturdy solution. Or, consider using a Structural Post Inserts instead of wood posts.

Posts for level rail are shorter than the posts that are used on the mid points or bottoms of stair cases. You will have options with most manufacturers for multiple lengths. The posts for the stairs should be 42" or taller for 36" rail.

Choose Post Caps

If you railing system does not include post caps and you are planning a post-to-post style rail, select your post caps. DecksDirect lists post caps according to the size of the opening of the cap. If you have a 4" post, you will need a post cap that is 4-1/16" or larger. Many railing manufacturers have post caps designed specifically for their systems. We also offer a variety of post cap options here.

Choose Skirts

If you railing system does not include post skirts, select your post skirts/flares to cover the attachment of the post to the deck. Most often you will choose the post skirt that is designed specifically for your railing system.

Choose Level Rail Kits

Try to order your rails sections as close to the length of sections on your deck for cost effectiveness. You can cut sections and use for two rail sections on your deck,
i.e (1) 8' section can be cut to (2) 4' sections. To do this you will need to order an additional rail hardware kit.

Choose Stair Rail Kits

Rail manufacturers differ in how these are sold, so check which systems are manufactured at a fixed angle and which are adjustable, then determine which of those options work best for you. Some manufacturers offer both options.

Find out if the system you chose meets the graspable handrail requirements. If it does not, or if you have a center post on your stair rail that interrupts the handrail from being continuous, a continuous graspable handrail may need to be installed. View our handrail options.

Additional Brackets

Order any additional brackets that you may need for angles or split rail sections.

Hardware

Most railing does not come with fastening hardware. The type of fastener needed will depend on the surface the railing is being fastened to. For example, if you are fastening to a wood or composite deck with blocking you will need a long structural screw. If you are installing a railing on a concrete patio, a concrete structural screw is needed. View all of our hardware options.

Lighting

Lighting is a great way to add interest and safety. If your deck has stairs, lighting is required by the International Residential Code (IRC). Some railing manufacturers offer a line of lighting that integrates seamlessly. View all of our deck lighting.
