Composite Decking: 5 Things Long Island Homeowners Need to Know

When Trex introduced its composite decking materials in the mid-90s, the game changed. They’re no longer the only composite decking provider. Still, they did what Band-Aid did with adhesive bandages, what Kleenex did with tissues, and what Tylenol did with acetaminophen — their brand became what most people called the actual product. If you hear “Trex,” you know you’re talking composite decking — whether it’s made by Trex or not.

Okay, this post isn’t actually about Trex. We’ve already been talking about them a lot (check out our guide on Trex and a post our owner, Joe, wrote to give some ballpark estimates on what Trex costs nowadays). We just wanted to give you some key things to know about composite decking and a bit more about what it is.

What Is Composite Decking?

Composite decking consists of wood fibers bonded with recycled plastics and special bonding agents to form a synthetic material. The composite blend creates a long-lasting deck material. It’s low maintenance. It’s not as strong as wood, but it’s hard to beat the stress-free life of having a deck that needs a rare cleaning and will last decades.

Composite boards stand out from wood because their resistance to rot, warping, and insect damage makes them the preferred option for homeowners who want durable outdoor spaces.

The Main Types of Composite Decking

Capped Composite Decking: The product contains a surface layer (cap) designed to block moisture. It also helps prevent stains and protects the deck from fading from sunlight. The bulk of the material is made from things like wood filler and recycled materials.

Uncapped Composite Decking: Uncapped decking doesn’t protect the core. I’d avoid this stuff, but it’s worth mentioning because you’ll hear some discussion about the differences between capped and uncapped composite decking.

The lower cost of uncapped composite decking comes at the expense of a protective outer layer, which leaves it vulnerable to fading and staining.

Most materials these days are capped, though.

 Composite Decking vs. Traditional Wood

You should evaluate composite decking against traditional wood before selecting which option satisfies your requirements best. Each has their strengths and weakness. For me and my team, composite is the clear winner. Why? It lasts and is easy to maintain. Imagine if you only had to clean your deck a handful of times a year and it lasted 30 years. That’d be nice, right? That’s what composite decking offers. Anyway, here are the pros and cons:

Pros of Composite Decking

Low Maintenance: Simple maintenance involves just cleaning with soap and water since staining and sanding aren’t necessary.

Long Lifespan: Composite decks endure for 25–30 years, which exceeds the lifespan of wooden decks.

Resistant to Rot and Insects: Won’t warp, crack, or attract termites.

Eco-Friendly: Made from recycled materials, reducing environmental impact.

Variety of Colors and Styles: The product replicates wood aesthetics while avoiding wood-related problems.

Splinter-Free: Safer for children and pets.

Cons of Composite Decking

Higher Upfront Cost: Generally more expensive than pressure-treated wood.

Heat Retention: Direct sunlight can make certain composite boards uncomfortably hot to the touch.

Less Natural Appearance: High-quality composite materials appear realistic, but some people still choose wood for its genuine appearance.

Thermal Expansion: Temperature fluctuations cause composite materials to expand and contract, influencing installation procedures.

Quick Summary

See. This was a quick and easy post. We simply wanted to give you some things you must know about composite decking before making a decision to use it for your next project. Obviously, we’re big fans. There’s just no better material for creating a deck that looks great and is going to last.
