Cedar and composite decking are both popular materials for outdoor projects, but they offer different benefits. Understanding their differences will help you choose the best option for your home.
Cedar and composite decking each have their own set of advantages and drawbacks. In this article, we’ll break down the key differences to help you make an informed choice for your next decking project.
When it comes to upgrading your outdoor space, choosing the right decking material can make all the difference. Cedar and composite decking consistently rank as two of the most popular options. One is a natural wood known for its warmth and beauty; the other is a manufactured material praised for its durability and low maintenance. While they may serve the same purpose, they offer very different experiences in terms of performance, upkeep, and cost.
The Nature of Cedar Decking
Cedar has long been appreciated for its organic beauty and natural resistance to pests and rot. Its soft, warm tones add character and charm to patios and backyards. Many homeowners love how it weathers over time, transitioning from its original golden brown to a silvery gray patina if left untreated. This aging process adds to its rustic appeal.
However, what cedar offers in aesthetics, it demands in maintenance. You’ll need to apply sealant or stain every couple of years to keep it looking fresh and protected from UV damage. Without regular care, cedar can warp or crack, especially in harsh climates. For a breakdown of cedar’s natural durability, check out this guide from Wood Magazine.
What You Get with Composite Decking
Composite decking, made from a mix of wood fibers and recycled plastics, is engineered for longevity. It mimics the appearance of wood but is designed to resist rot, splinters, mold, and insect damage. This makes it a solid choice for homeowners who want a low-maintenance deck that still looks clean and polished over time.
While the initial cost is higher than cedar, composite decking often pays off in the long run. You won’t need to stain, paint, or seal it, and the cleaning process is as simple as using soap and water. It’s also available in a wide range of colors and grain patterns, which makes it easy to match your home’s style. For a deeper comparison of composite materials, explore this article from The Spruce.
Durability and Maintenance Over Time
In terms of longevity, composite decking tends to outperform cedar. While cedar can last 15 to 20 years with regular care, composite decking may hold up for 25 to 30 years or more. It’s less likely to fade, crack, or attract insects. That said, composite isn’t indestructible—it can stain from grease or dirt if not cleaned periodically, and some cheaper brands may scratch easily.
Cedar requires more active upkeep. You’ll need to watch for mildew, seal the boards every couple of years, and possibly sand down splinters or rough edges. However, some homeowners appreciate this hands-on care, seeing it as part of maintaining a beautiful, living material. If you’re unsure which material lasts longer under real-world conditions, Bob Vila’s comparison article provides a useful breakdown.
Appearance and Aesthetic Choices
If you’re going for a classic, earthy look, cedar delivers with its unique grain, natural color, and warmth. Every board is slightly different, which gives your deck a more organic feel. Over time, cedar’s aging process gives it a weathered, coastal appearance that some homeowners love. You can also stain it to match your outdoor theme.
Composite decking, while not "alive" like cedar, has come a long way in terms of aesthetics. Many modern brands offer embossed grain patterns, color variations, and even distressed finishes to emulate the look of real wood. While it lacks the scent and texture of cedar, it stays looking new for much longer with very little effort. For many, that trade-off is worth it.
Environmental Factors and Sustainability
If you’re thinking green, both cedar and composite have eco-friendly options. Cedar is renewable and biodegradable, especially when sourced responsibly. Many suppliers now offer FSC-certified cedar that ensures ethical harvesting practices. However, the use of chemical sealants or stains can reduce its environmental benefit.
Composite decking is often made from recycled plastic and reclaimed wood waste, which keeps materials out of landfills. That said, it’s a manufactured product and not biodegradable. Some brands focus more on sustainability than others, so it’s worth researching where and how the boards are produced. Trex and TimberTech, for example, have strong sustainability programs—learn more on Trex’s official site.
Final Thoughts: What’s Right for You?
Your decision really comes down to your priorities. If you value a natural look and don’t mind putting in the work, cedar might be the better fit. It’s perfect for homeowners who enjoy traditional materials and are willing to maintain them over time. On the other hand, if you prefer to “install it and forget it,” composite decking is hard to beat. It’s low-maintenance, consistent in appearance, and highly resistant to environmental stress.
Also consider your climate. In areas with extreme weather changes or high humidity, composite tends to hold up better. In dry, temperate climates, cedar can last quite well too—as long as you stay on top of maintenance.
Conclusion
Cedar and composite decking both have strong cases depending on your lifestyle, design preferences, and budget. Cedar offers warmth, authenticity, and tradition, while composite delivers longevity, convenience, and performance. By understanding the strengths and limitations of each material—and factoring in long-term maintenance—you can make a smart investment that brings years of enjoyment to your outdoor space.
If you’re still torn, consider visiting a local lumberyard or home improvement store to see samples side-by-side. Sometimes, the right choice becomes clear the moment you touch the wood—or the composite.
