Composite decking has revolutionized outdoor construction, yet many misconceptions still cloud its reputation. If you're planning to build a deck and weighing your options, it's important to separate outdated myths from current facts.
As a trusted TrexPro Platinum Builder, Warner’s Decking knows first-hand how far composite technology has come. And how it consistently outperforms traditional wood in real-world use.
In this guide, we’ll walk you through the most common myths surrounding composite decking, clear up confusion, and give you expert-backed insights to help you make the right decision for your outdoor space. By the end, you'll have the facts you need to feel confident in your choice.
Key Takeaways
Composite decking offers superior durability and longevity compared to traditional wood options
Modern composite materials provide diverse design options and excellent slip-resistance
The long-term value of composite decking often outweighs its higher initial cost
Composite decking requires minimal maintenance and resists weathering, warping, and insect damage
Environmentally friendly composite options contribute to sustainable building practices and tree conservation
1. Composite Decking Is Inferior to Traditional Wood Options

You might have heard that composite decking doesn’t match up to real wood, but that’s simply not true. In fact, composite materials outperform traditional wood in nearly every category that matters to you as a homeowner.
Made from a blend of recycled wood fibers and plastic, composite boards resist warping, rotting, and insect damage, which are common issues that wood struggles with over time.
Characteristic | Composite Decking | Traditional Wood |
Durability | Highly resistant to rot and insects | Susceptible to rot and insect damage |
Maintenance | Low maintenance, no staining required | Regular staining and sealing needed |
Lifespan | 25+ years | 10-15 years on average |
With proper installation and minimal upkeep, your composite deck can deliver reliable, long-term performance.
2. Composite Decking Is Maintenance-Free

It’s easy to think composite decking requires zero effort, but like any outdoor surface, it still needs occasional care. You won’t need to seal, stain, or treat it like wood, but basic cleaning is key to keeping it looking its best.
To maintain your deck, all you really need to do is:
Rinse or sweep away debris regularly
Clean spills quickly to prevent surface staining
Wash with soap and water now and then
Use a plastic shovel to remove snow to avoid scratching
Compared to wood, this is a breeze.
3. Composite Decking Warps and Expands

If you’ve been warned that composite decking warps over time, that advice is outdated. Early versions had some issues, but today’s composite boards are engineered to resist warping when installed correctly. Manufacturers have resolved past concerns through advances in core design and surface protection.
Wood decks, on the other hand, still expand and contract due to temperature and humidity changes. Composite decking, when installed with proper spacing, remains dimensionally stable and won’t buckle or distort with seasonal shifts.
4. Composite Decking Fades Quickly
Worried your deck will lose its color after one summer? You don’t need to be. Modern composite decking is designed with UV-resistant technology that helps it maintain its rich tones for years. Unlike untreated wood, which bleaches and grays quickly under sun exposure, composite boards are built to resist fading.
Many manufacturers, including Trex, back this with fade and stain warranties that last between 25 to 50 years. Don’t hesitate to visit your closest Chicagoland deck builder to inspect the boards in person before construction to ask and confirm these points.
5. Composite Decking is Prone to Mold and Mildew

Mold grows where there’s moisture and organic material. While no outdoor surface is completely immune, composite decking resists mold far better than wood. That’s because it doesn’t absorb moisture the way wood does.
With routine cleaning and proper airflow, you can easily keep mold and mildew at bay. The key is simply to remove debris and avoid moisture buildup, just as you would with any outdoor structure.
6. Composite Decking Gets Too Hot in the Sun
It’s true that any surface left in the sun will warm up, but composite decking is not significantly hotter than wood. In fact, many modern composite brands use heat-reflective technology and color options to reduce surface temperatures. If you choose lighter colors and plan for shade, your deck will stay more comfortable in direct sunlight.
7. Composite Decking is Slippery When Wet

Slipping on wet surfaces is a concern, but composite decking is actually designed to be safe underfoot. Most boards feature textured or embossed surfaces to enhance traction. When clean and dry, composite decking performs as well or better than wood. Some models are even made for poolside use, where wet conditions are expected.
8. Composite Decking Looks Artificial
Older composite boards may have had a plasticky appearance, but those days are gone. Today’s composite decking uses advanced manufacturing techniques to mimic the texture, grain, and color variations of real wood.
Some composite decking manufacturers even offer multi-tonal finishes that look just like natural hardwoods. You get the beauty of wood without the fading, cracking, and splintering.
9. Composite Decking Isn’t Environmentally Friendly

If you’re trying to build sustainably, composite decking is a great choice. Many products are made using recycled wood fibers and plastics. In fact, Trex composite decking alone keeps hundreds of millions of pounds of waste out of landfills every year.
A 2024 report from the American Chemical Society highlighted that composite decking significantly reduces the carbon footprint of outdoor construction. It helps reduce deforestation and limits the need for harmful chemical treatments required for preserving wood.
10. Composite Decking Doesn’t Justify the Price
Composite decks may cost more upfront, but you save in the long run. You won’t have to budget for sealants, repairs, or replacements every few years. With a lifespan of 25 to 50 years and minimal maintenance, the cost-per-year is often lower than wood.
Plus, composite decks boost home value and curb appeal, especially when installed by a certified expert like Warner’s Decking.
