Wood vs. Composite Decking - Which Is Right for You?
Choosing deck boards is the biggest decision in any deck project. It sets your budget, how much weekend maintenance you'll do, and how the deck looks in ten years. Here's how the main options compare.
Pressure-treated wood
The most common and least expensive choice. Pressure-treated (PT) lumber is chemically treated to resist rot and insects.
Pros: lowest upfront cost, widely available, easy to work with. Cons: prone to checking, splitting, and warping; needs regular cleaning and sealing or staining.
Note that the deck's framing (joists, beams, and posts) is usually pressure-treated regardless of what boards you put on top.
Cedar and redwood
Naturally rot-resistant softwoods with attractive color and grain.
Pros: beautiful, lighter weight, stays cooler underfoot than many composites. Cons: softer and more easily dented; costs more than PT; still needs regular finishing to keep its color.
Tropical hardwoods
Species such as ipe are extremely dense and durable.
Pros: very long-lasting, highly resistant to wear and decay, premium look. Cons: expensive, heavy, hard to cut and fasten (often requires pre-drilling and special fasteners). Look for responsibly sourced, certified wood.
Composite and PVC decking
Composite boards blend wood fibers and plastic; PVC boards are fully synthetic. Both are designed for low maintenance.
Pros: no staining or sealing, resistant to rot and splinters, consistent color, long warranties. Cons: higher upfront cost; can get hot in direct sun, especially darker colors; can scratch; some products can show mold or stains if not cleaned.
How to decide
Ask yourself:
- How long will I live here? Short timeline favors lower upfront cost; long timeline favors low maintenance.
- How much maintenance will I really do? Be honest. A wood deck that never gets sealed ages badly.
- How much sun does the deck get? In hot, sunny climates, choose lighter colors or materials that stay cooler.
- What's my total budget? Include fasteners, railings, and stairs: railings can cost as much as the boards.
Total cost of ownership
Wood is cheaper on day one. Composite often closes the gap over many years because you skip repeated cleaning, staining, and board replacement. Compare the upfront price plus expected maintenance over the years you'll own the home.
Whatever you choose, follow the manufacturer's installation instructions exactly: especially board spacing and fastener type. Many warranties depend on it.
