Composite vs Wood Deck: Cost, Maintenance & Lifespan Comparison
Thinking about adding a deck to your home? One of the first decisions you'll face is: composite or wood? Both have real advantages. This guide breaks down the cost, maintenance, and lifespan of each so you can pick the right one for your home and budget.
What Is the Difference Between Composite and Wood Decking?
Wood decking is exactly what it sounds like natural lumber, usually pressure-treated pine, cedar, or redwood. It has been the traditional choice for decades.
Composite decking is made from a mix of wood fibers and recycled plastic. It looks like wood but behaves very differently over time.
Cost Comparison
Upfront Cost
Wood decking is cheaper to install upfront. A pressure-treated wood deck typically costs $15 to $25 per square foot installed. Composite decking runs $25 to $45 per square foot installed, depending on the brand and style.
For a 400-square-foot deck:
- Wood: $6,000 to $10,000
- Composite: $10,000 to $18,000
Long-Term Cost
Here is where composite starts to catch up. Wood requires staining, sealing, and sometimes sanding every one to three years. Those costs add up fast. Composite needs almost no maintenance beyond occasional cleaning.
Over 20 years, the total cost of ownership often evens out — and composite can come out ahead.
Maintenance Requirements
Wood Deck Maintenance
- Stain or seal every 1–3 years
- Check for rot, splinters, and warping annually
- Replace boards as needed
- Power wash regularly
Composite Deck Maintenance
- Rinse or scrub with soap and water once or twice a year
- No staining or sealing ever needed
- Inspect for mold or mildew in shaded areas
If you are someone who would rather spend weekends relaxing than doing deck upkeep, composite is the clear winner.
Lifespan
A well-maintained wood deck lasts 15 to 25 years. In coastal Monmouth County, where salt air and humidity speed up deterioration, that number can be closer to 10 to 15 years without proper care — something our team sees regularly when handling home repairs in West Long Branch and coastal communities.
Composite decking is designed to last 25 to 30 years or more. Most premium brands come with warranties of 25 years or longer.
Which One Should You Choose?
Choose wood if:
- You want a lower upfront cost
- You enjoy the look and feel of natural lumber
- You are comfortable with regular maintenance
Choose composite if:
- You want a low-maintenance option for the long run
- You live near the coast where moisture is a constant challenge
- You plan to stay in your home for many years
