Key Takeaway: Composite decking costs more upfront but saves money and effort over time with its durability and low maintenance. Wood decking is cheaper initially but requires more upkeep and may need replacement sooner. Choose based on your budget, climate, and long-term goals.


Composite vs. Wood: Basic Differences


How Each Material is Made

Wood decking is crafted from natural timber, often using pressure-treated pine, cedar, or redwood. These woods are treated to resist decay and insect damage. On the other hand, composite decking blends reclaimed wood fibers with recycled plastics and includes protective additives to boost durability. This combination creates a low-maintenance option that also repurposes materials.


Environmental Considerations

When it comes to environmental impact, the two materials differ quite a bit. Wood decking is made from a renewable resource, but its production can raise concerns about forestry practices and their effects on ecosystems and wildlife habitats. Opting for FSC-certified wood ensures that the timber comes from responsibly managed forests, making it a more eco-conscious choice when sourced properly.

Composite decking stands out for its use of recycled materials. Many top manufacturers incorporate up to 80% recycled content in their boards, helping to reduce landfill waste. Beyond production, composite decking avoids the need for chemical treatments and stains, cutting down on harmful substances released into the environment.

These differences in how the materials are made and their environmental impact play a key role in their cost, durability, and how well they fit different needs. Knowing these basics helps set the stage for evaluating their overall value and long-term performance.


Cost Breakdown: Short-Term vs. Long-Term


Purchase and Setup Costs

When comparing the upfront costs of wood and composite decking, the price difference is clear. Wood decking materials typically range from $2 to $10 per square foot, while composite decking costs between $3 and $15 per square foot. Labor costs for installation are about $12 per square foot for both options.

Here’s a breakdown for a standard 16 x 20 foot (320 square feet) deck:

Yearly Upkeep Tasks

Wood decks require consistent maintenance to stay in good shape. Typical yearly tasks include:

  • Staining: Costs about $3 per square foot (labor included) and needs to be done every 2-3 years.
  • Sealing: Costs around $2 per square foot (labor included) and is required annually.
  • Power Washing: Costs vary but is generally recommended once a year.

In contrast, composite decking needs far less upkeep - mainly occasional cleaning with soap and water, which keeps costs minimal.


20-Year Cost Projection

Composite decking, which lasts 25-30 years, offers significant savings on maintenance over time. Wood decking, however, often requires major repairs or even replacement within 10-15 years.

Here’s a 20-year cost comparison for the same 320-square-foot deck:

This comparison highlights why many homeowners are opting for composite decking. While it comes with a higher upfront cost, the long-term savings on maintenance and repairs are hard to ignore. Plus, the reduced need for chemical treatments over time adds an eco-friendly bonus. These cost factors are key when weighing durability and performance in your decking decision.


Strength and Longevity


Protection Against Weather

Composite decking stands up better to harsh weather compared to wood. TimberTech's composite decking, for example, includes a protective polymer layer that defends against moisture, UV rays, and temperature changes. This design helps prevent issues like warping and rotting that are common with wood decks.
