How to Choose the Right DIY Decking Materials

July 14, 2021

Once you’ve decided to DIY your deck build, your next step is choosing your deck materials. You likely want a material that’s easy to source, a great value, and straightforward to install. While wood is likely the first material you think of, it’s not the only — nor even the best — option. To help in your decision, we’ve analyzed three common DIY decking materials so you can choose the right one for your project.

A Closer Look at Traditional Wood

While all wood deck boards fall under the larger category of “traditional wood,” it’s important to note that there are, of course, different kinds of wood — with different properties and performance qualities.

You may think that the more expensive the upfront cost of a given category of wood, the better that wood will perform. After all — why pay premium prices for an exotic hardwood like Ipe if it’s not going to stay beautiful after you install it?

But here’s the harsh reality: Across categories, traditional wood can’t measure up to our capped composite and capped polymer DIY decking materials.

We’ll break down exactly why — and how to choose the right material for your backyard build.

DIY Decking Materials: What to Consider

To determine which materials are best for your outdoor living space, we ranked these DIY decking materials across four key categories:

• Durability
• Upfront Cost vs Long-Term Value
• Installation Ease
• The Best-Looking

Durability: Wood vs Composite Decking

Durability is about more than strength of material — when it comes to DIY decking materials, greater durability means less maintenance for you. And after all the work you put into installing your deck, you should be able to sit back and enjoy it — not worry about maintenance work.

As for maintenance needs? Both our capped polymer decking and capped composite decking need an occasional clean and rinse with the appropriate brush and our TimberTech® DeckCleaner™.

With a traditional wood deck, the work doesn’t stop after installation. You’ll need to sand, stain, and seal the boards annually to keep your deck structurally sound — and even more often to keep it looking new and richly-hued.

Upfront Cost vs Long-Term Value

For a fuller picture, compare upfront and long-term costs in the infographics below:

NOTE: The estimated average cost of capped polymer deck boards and Ipe hardwood decking costs are based on the national average for a 16’ x 20’ deck. Meant for visual representation only. Actual costs may vary.

NOTE: The estimated average cost of composite deck boards and pressure-treated lumber decking costs are based on the national average for a 16’ x 20’ deck. Meant for visual representation only. Actual costs may vary.

Best Long-Term Value: TimberTech Composite Decking

As you can see, capped polymer and capped composite decking wins when it comes to long-term value, meaning they save you money in the long-run.

How? TimberTech decking is designed with advanced materials science to retain its beauty and integrity for years, all with little upkeep from you.

Plus, with industry-leading warranties, you can be sure your TimberTech deck will last, with little chance of repair or replacement costs.

Upfront costs are one-time charges for the initial materials — but when considering the overall costs of your deck, it’s not the only cost to budget for. Maintenance work and potential repair and replacement costs should also be considered.

Least Long-Term Value: Traditional Wood

Initially, it might seem that pressure-treated wood — wins on upfront costs, but that’s not the whole story. High quality woods such as exotic hardwoods can be more expensive upfront than some composite options — and the costs don’t stop there.

As the least durable of DIY decking materials, all traditional wood options require the most maintenance and are highly vulnerable to frequent repairs or full deck replacement.

The Accumulating Costs of Wood

As an organic material, wood is prone to deterioration and comes with very limited warranty coverage.

To maximize your wood deck’s lifespan, you will likely need to perform extensive maintenance work on an annual — or more frequent — basis, driving up your costs year after year.

Installation Ease

Unless you’ve worked with composite decking before, you may think traditional wood is the familiar, easier route go.

Familiar — perhaps. But easier? Nope. The reality is that many installation best practices for wood are similar to those for composite decking.

Just like with wood, you will need to consider:

• Deck board spacing
• Joist blocking and spacing
• Appropriate fasteners and tools for application
• Appropriate cutting tools
• Storage conditions

The Easiest Decking Material to Install

If you’re unsure about going with a wood alternative, fear not: Our TimberTech Advanced PVC capped polymer boards offer a few extra advantages that will help set your project up for success.

TimberTech Advanced PVC Capped Polymer Boards

• Are up to 30% lighter than competitive composite products (your back will thank you).
• Don’t require pre-drilling, like hardwoods do, saving you valuable installation time.
• Are designed to resist cracking, splitting, and mushrooming when top-down fasteners are correctly installed.

TimberTech Deck Board & Fastener Pairings

Your installation process will vary depending on the board material, board profile, and fastener you choose. Keep in mind, certain fasteners are only compatible with certain boards.

For already curated pairings, try these:

The Best-Looking

When you think of a good-looking deck, you likely think of one with rich hues and tonal variation. While premium hardwoods like Ipe are known for their natural beauty, as an organic material, they will eventually fade to gray — some after darkening first.

For DIY decking materials that are rich in color and exhibit minimal fading over time, ditch wood for good.

Beauty That Fades: Traditional Wood

Regardless of how rigorous your maintenance schedule, traditional wood — from pressure-treated lumber to premium hardwoods — will inevitably fade.
