A deck is the workstation of a yard. Washing off sandy feet, grilling with friends, or just enjoying a morning coffee in the marine layer. A lot happens here. As a designer and builder, I’ve seen how the Southern California sun and our unique coastal air treat outdoor spaces. When choosing a material, you want to make sure you’re maximizing its potential for the long haul.
We’re often asked by homeowners from the Palisades to the Venice Canals which features we always recommend to combat our local elements. Composite decking is the one that comes up again and again.
What is a composite deck?
I like to describe composite as the evolution of the outdoor floor. It is a modern system designed to replicate the appearance of natural wood while eliminating the organic weaknesses that lead to rot.
Most high-performance boards I install today are capped. This means the core is wrapped in a high-density outer shell that protects against moisture and UV rays. It is essentially a low-maintenance alternative that stays looking like it was installed yesterday, even years down the line.
What is composite deck made of?
The boards are an amalgamation of recycled wood fibers and recycled plastics. These materials are bonded together with pigments and UV inhibitors to create a dense, heavy-duty plank that won’t splinter.
Using materials like sawdust and recycled shopping bags allows brands like Trex and TimberTech to keep millions of pounds of waste out of landfills. For my clients who prioritize sustainability, this is usually a major selling point.
Why we love it for our Westside builds?
In our local pockets, we deal with the “Coastal Paradox.” People want a natural, beachy aesthetic, but our environment is often hostile to real wood.
- Marine Layer Protection: The heavy morning fog in Santa Monica and Venice can settle into wood grain and lead to internal rot. Composite is moisture-resistant and does not swell.
- Salt Air Resilience: Near the bluffs or North of Montana, salt air acts like sandpaper on wood finishes. The protective cap on composite prevents salt from degrading the board.
- Safety and Comfort: In neighborhoods like the Oxford Triangle, families spend a lot of time barefoot. Composite never splinters, which makes it a safe choice for kids and pets.
- Premium Aesthetics & Integration: Beyond durability, modern composite looks and feels premium. Because it is an engineered system, we can do cool things with it like seamless LED light integration (think recessed stair lights and glowing post caps) that turn the deck into a high-end lounge after the sun goes down.
How much is composite decking?
The cost depends largely on the tier of the board you choose. Rolling into 2026, high-quality capped composite materials typically cost between $16 and $32 per square foot for the boards alone.
It is important to keep in mind that this reflects the material cost. It does not include the substructure, demolition of an old deck, or the skilled labor required for installation and add-ons like integrated LED lighting.
Why is composite decking so expensive?
While the upfront price is higher than pressure-treated lumber, I encourage clients to look at it as a long-term investment. Composite is a premium product because of the engineering required to make it weatherproof.
Of course, project costs vary depending on exactly where you are building. I always recommend checking within your local area, as labor rates and permitting fees can fluctuate significantly across Southern California.
However, investing in a deck in Los Angeles specifically reflects the demands of our unique market. My team and I navigate specific Westside and Southbay requirements every day, from the hillsides of Bel Air to the coastal lots of Santa Monica. You are paying for the expertise needed to ensure a deck is built to last in our specific coastal climate. We also have some of the highest safety and structural standards in the country, meaning a deck built here is engineered for better stability and longevity.
Ultimately, it pays for itself in maintenance savings within the first decade because you skip the cost of professional sanding and staining every two years.
How long does a composite deck last?
These boards are built for the long haul. Most manufacturers I work with offer a 25-year to 50-year warranty against fading and staining. While a standard redwood deck might show signs of decay after 15 years in our damp air, a composite deck can easily last twice that long while maintaining its integrity.
Composite deck or wood – what’s better?
There isn’t one single perfect material, only the right one for your goals.
- Choose Wood if you are a purist who loves the smell of natural timber and you actually enjoy the ritual of power washing and staining every other year to keep it fresh.
- Choose Composite if you want a “set it and forget it” lifestyle. It is the best fit for busy families who want to enjoy their deck rather than work on it.
Composite vs PVC – whats better?
While both are excellent and appear similar, they serve different needs. Composite uses wood fibers, which gives it a more realistic, matte wood look. It is often my first choice for luxury estates in Brentwood Park
PVC is 100% plastic and even more moisture-resistant. It is often engineered to stay cooler in direct sun. If you have a rooftop deck in the South Bay with no shade, PVC might be the better barefoot option, even if it looks slightly more synthetic.
Got Questions About Decking?
Whether you are looking for light beach-house grays or the deep tones of mahogany, composite decking allows us to capture the Southern California aesthetic without the maintenance headache. But choosing the right material is a big decision, and every property from the Palisades to Manhattan Beach has its own unique sun exposure and micro-climate to consider.
