The Ultimate Buying Guide to the Best Composite Decking

What is Composite Decking?

Composite decking is made from natural wood fibers mixed with recycled plastics. This combination creates deck boards that look and feel like natural wood, but are far more durable and require less maintenance.

Benefits of Composite Decking

Thanks to its innovative composition, the best composite decking offers numerous advantages, including:

• Never requires painting, staining, or sealing
• Doesn't crack, split, rot, or splinter
• Doesn't weather or fade like wood - the look you install is the look you get long-term
• Long-lasting and typically protected by lengthy manufacturer warranties
• Eco-friendly: made from recycled materials

Composite Vs Wood Decking: Pros & Cons

When you compare the best composite decking to wood, you'll find that composite provides many advantages over its natural counterpart.

Composite Decking

Pros:

• More durable and longer lifespan
• Low-maintenance: never needs painting, staining, or sealing - just a simple cleaning a few times a year
• Termite-proof
• Doesn't fade, stain, crack, split or splinter
• Saves money in maintenance/repair costs across the life of your deck

---

Cons:

• Higher initial cost
• Uncapped composites can scratch easily
• Looks can range from high-end to artificial-looking, so it's important to pick the right brands and lines

Wood Decking

Pros:

• Cheaper initial cost
• Natural look and feel
• Classic, traditional deck look

---

Cons:

• Shorter lifespan: will need replacement in 10-20 years or less
• Requires staining and sealing every few years
• Regular exposure to rain and moisture will cause rotting, warping, cracking and splintering over time
• Looks fade much faster without diligent staining, painting, or sealing

Wood or Composite: Which Decking Is Best For You?

From appearance to price to performance, we dive into the key differences between traditional deck boards and modern composite decking.

Compare Materials

Grooved Edge vs Square Edge Composite Decking

First, let's explore the difference between grooved edges and square edges.

Grooved Edge Boards

Grooved edge boards are designed for use with hidden deck fasteners for a smooth, unblemished deck surface.

Square Edge Boards

Traditional square-edge boards are designed to use face-fastening screws. They're also best for places where the edge of the deck board will be visible, like the outsides of your deck, stair treads, or drink rails.

Solid Bottom vs Scalloped Bottom Composite Decking

It's also useful to compare composite decking boards that have solid bottoms against those that have scalloped bottoms.

Solid Bottoms

Most composite deck boards have solid bottoms - a flat surface underneath your deck board and a consistent thickness across the board.

Scalloped Bottoms

One way to save money on a composite deck is to use a board with scalloped bottoms. They use less composite material to keep costs down, and are lighter and easier to transport.

However, you can't use scalloped boards as drink rails on top of a railing, and they typically can't use plug systems to hide your fasteners like solid boards can.

Capped vs Uncapped Composite Decking

The best composite decking has evolved over the years. One of the most obvious areas of improvement is the switch to capped composite deck boards.

Early generations of composite decking were often uncapped and easy to scratch. So decking manufacturers developed tough, protective shells to make the walking surface of each board more durable.

The 3-sided capping makes boards more resistant to scratching and protects the boards better from the outdoor elements. We highly recommend capped composite deck boards, and every board you'll find in DecksDirect's selection is complete with a high-performance cap.

4-sided capping: Some decking lines go the extra mile and cap each board on all four sides. If you want the best weather resistance possible, check out TimberTech or Fiberon deck boards, which are capped on all four sides.

Initial vs Long-Term Costs

Composite decking will cost more up front than most types of wood. But long-term, composite decking will save you time and money in yearly maintenance. Finding the right material for you depends on how you want to balance initial vs long-term costs.

Estimated Initial Costs For Different Decking Materials

Based on research from HomeAdvisor and Home Guide.

Comparing Long-Term Costs: Wood vs Composite

Here's a quick long-term estimate for a standard 16-foot by 20-foot deck using composite or pressure-treated wood deck boards.

We've used numbers right in the middle of the HomeAdvisor/Home Guide estimate ranges above:

• Estimated material costs: $5 per square foot for wood and $13 per square foot for composite
• Estimated labor costs: $12 per square foot for either material
• Estimates don't include fasteners or other features like framing or railing
• Estimated maintenance costs: staining ($3 per square foot) and sealing ($2 per square foot), including labor and materials

*For 16x20 deck - not including fasteners, framing, etc.

The best composite decking allows you to create a clean, unblemished decking surface, with hidden fastening methods that blend in far better than standard wood screws.

Here are the three most common ways to hide your deck board fasteners:

Hidden Fasteners

Choose grooved-edge composite deck boards to work with hidden fasteners that fit between the boards, securing them to your framing without puncturing the boards themselves.

Most decking brands offer their own specialized hidden fasteners, designed to work perfectly with the shape of their deck boards grooves.

Benefits:

• Smoothest, blemish-free deck surface
• Doesn't puncture deck board capping
• Easy to replace boards if needed

Shop Hidden Fasteners

Plug Systems

Plug systems give you the superior strength of traditional face-fastening - but the screws countersink beneath the surface of your deck boards.

Perfectly color-matching plugs, made from the exact same material as your deck boards, fit in the hole above the screw, completely disappearing once installed.

Benefits:

• Strongest hold-down power
• Smooth, unblemished deck surface
• No risk of screw heads sticking up
• Protects screws from corrosion

Shop Plug Systems

Standard Face-Fastening

Color-matching screws are designed to perfectly match the color tones of your composite deck boards, camouflaging into your deck surface once installed.

Benefits:

• Strongest holds
• Easy, fast installation

Shop Composite Screws

Composite decking never needs to be painted, stained, or sealed, unlike wood decking, which requires re-staining and re-sealing every year or two.

That'll save you tons of money in the long run, not to mention hours of back-breaking summer deck staining. Trust us: once you've stained a deck under the hot summer sun, you'll never want to do it again.

To keep the best composite decking strong and looking great, you'll need to periodically clean your deck. You can sweep away most debris with a simple household broom and a quick spray with a garden hose.

Even a deeper spring cleaning is easy: just use warm, soapy water and a soft bristle brush on any stubborn spots of stuck-on dirt or debris.

Does Composite Decking Get Hot On Sunny Days?

All decking materials, including wood or composite, will heat up in direct sunlight. While composites do heat up faster than wood, decking material is not the biggest factor in creating a barefoot-friendly deck. Here are the three biggest factors controlling deck board temperature:

1. Decking color
2. Direct sunlight
3. Ambient temperature

If your deck is in direct sunlight, we recommend choosing a lighter color for your deck boards - light grays and light browns tend to absorb less heat from the sun compared to darker shades.

You can also try to limit the amount of direct sunlight and the temperatures around your deck by installing shade structures like pergolas or umbrellas.

Ultimately, these factors will matter more in keeping your deck cool than the decking material you use.

Certain deck boards are also designed to stay cooler, too. Trex's Transcend Lineage decking line uses new capping technology to stay cooler in the sun than most composites. And TimberTech's Advanced PVC decking will heat up slower and cool down faster than typical composites.

Can I Curve Composite Deck Boards?

Yes! You can create unique deck patterns by curving or bending composite deck boards. First, you'll heat the deck boards, then bend them to the angle you need. You'll likely need to work with an experienced local contractor to take advantage of this feature. If you're interested in curving deck boards, we'd recommend giving our team a call at 1-888-824-5316 to help you draw up a complete deck plan your contractor can follow.
