Composite vs. Wood vs. PVC Decking: Which Material Will Last 20+ Years?

Choosing the right decking material is one of the most important decisions you'll make for your outdoor living space. With so many options available, homeowners often feel overwhelmed by the choices between composite decking, traditional wood, and PVC materials. The decision you make today will impact your enjoyment, maintenance requirements, and costs for the next two decades.
As a TimberTech Platinum Contractor, we've installed thousands of square feet of every major decking material. Here's what 15+ years of experience has taught us about which materials truly deliver on their promises.
The Three Main Decking Material Categories
Understanding Your Core Options
When homeowners research deck building materials, they encounter three primary categories:
Traditional Wood Decking:
- Pressure-treated lumber
- Cedar and cedar-toned options
- Exotic hardwoods
Composite Decking:
- Wood fiber and plastic blends
- Multiple tier options and warranties
- Brand variations (TimberTech, Trex, etc.)
PVC Decking:
- 100% synthetic materials
- Premium positioning and pricing
- Superior stain and fade resistance
Each category has distinct advantages, limitations, and ideal use cases that we'll explore in detail.
Wood Decking: The Traditional Choice
When Wood Makes Sense
Pressure-treated lumber decking remains popular for specific situations:
Initial Cost Advantage:
- Lowest upfront material cost ($8-15 per square foot)
- Readily available at all lumber yards
- DIY-friendly installation process
Natural Appearance:
- Authentic wood grain and texture
- Takes stain colors beautifully
- Traditional aesthetic appeal
Workability:
- Easy to cut, modify, and repair
- Accepts standard fasteners
- Familiar to most contractors
The Reality of Wood Deck Ownership
However, wood deck maintenance requirements are extensive:
Annual Maintenance Cycle:
- Power washing (spring)
- Staining or sealing (annually or bi-annually)
- Board inspection and replacement
- Hardware tightening and adjustment
Long-term Costs:
- Annual maintenance: $500-$1,200
- Board replacement (years 10-15): $2,000-$5,000
- Complete rebuild (years 15-20): $8,000-$15,000
Performance Issues:
- Warping and cupping over time
- Splintering and cracking
- Insect damage potential
- Mold and mildew growth in humid conditions
