Composite vs Wood Decking: Key Differences Explained
Compare composite and natural wood decking to choose the best material for your outdoor deck project.
Quick Answer
Composite costs more upfront but saves on maintenance; wood costs less initially but requires ongoing care.
| Feature | Composite Decking | Wood Decking |
|---|---|---|
| Made from recycled plastic and wood fibers | Natural lumber (cedar, redwood, pressure-treated) | |
| $8-$15 per sq ft material | $3-$8 per sq ft material | |
| Virtually maintenance-free | Requires staining/sealing every 1-3 years | |
| Lasts 25-50 years | Lasts 10-30 years depending on maintenance | |
| Does not splinter or rot | Can splinter, warp, and rot over time |
Composite decking is engineered from a blend of recycled wood fibers and plastic, offering a low-maintenance alternative to natural wood. It resists rot, insects, and fading, and never needs staining or sealing.
Natural wood decking provides an authentic look and feel at a lower upfront cost. Cedar and redwood are naturally rot-resistant, while pressure-treated pine is the most affordable option. All wood decks require regular maintenance.
When to Use Composite Decking
- You want a low-maintenance deck
- Long-term cost savings matter more than upfront price
- You live in a humid or insect-prone climate
When to Use Wood Decking
- You want the lowest upfront cost
- You prefer the natural look and feel of real wood
- You enjoy DIY deck maintenance projects
Worked Example
A 300 sq ft deck over 20 years.
Composite Decking
Composite: $6,000 material + $0 maintenance = $6,000 total.
Wood Decking
Wood (PT pine): $2,400 material + $3,000 maintenance (staining every 2 years) = $5,400 total.
Over 20 years, total costs are similar, but composite requires zero maintenance effort.

Frequently Asked Questions
Does composite get hot in the sun?
Yes, composite decking can get significantly hotter than wood in direct sunlight. Choose lighter colors to reduce heat.
Can I paint or stain composite?
It is not recommended. Composite is designed to maintain its color without finishing.
Which is more eco-friendly?
Composite uses recycled materials and lasts longer, reducing waste. However, wood is biodegradable and renewable.
