Composite vs. Wood Decking
Composite vs. Wood Decking: A Pennsylvania Homeowner's Complete Guide
As a deck builder serving Monroe County for over [X] years, I've helped hundreds of Pennsylvania homeowners navigate one of the most important decisions in their deck project: choosing between composite and wood decking materials. With our unique climate challenges—from humid summers to harsh winters with ice and snow—this choice can make or break your deck's longevity and your satisfaction with the investment.
Let me walk you through everything you need to know to make the right decision for your Pennsylvania home.
Understanding Pennsylvania's Climate Challenges
Before diving into materials, it's crucial to understand what your deck will face in our region:
Temperature swings: From sub-zero winters to 90°F+ summers
High humidity: Especially during summer months
Heavy snow loads: Up to 30+ pounds per square foot in the Poconos
Freeze-thaw cycles: Can cause significant expansion and contraction
UV exposure: Intense summer sun that can fade and damage materials
Wood Decking: The Traditional Choice
Types of Wood Popular in Pennsylvania
Pressure-Treated Pine
Most affordable option
Readily available at local lumber yards
Requires regular maintenance every 2-3 years
Lifespan: 10-15 years with proper care
Cedar
Naturally weather-resistant
Beautiful grain patterns
Higher upfront cost but longer lasting
Lifespan: 15-20 years
Redwood
Premium option with natural rot resistance
Limited availability in Pennsylvania
Most expensive wood option
Lifespan: 20+ years
Pros of Wood Decking in Pennsylvania
Natural Beauty: Nothing matches the authentic look and feel of real wood. Each board has unique character, and the natural aging process can be beautiful when properly maintained.
Cost-Effective Initial Investment: Pressure-treated lumber costs significantly less upfront than composite materials—often 30-50% less.
Easy Repairs: Damaged boards can be easily replaced without affecting the entire deck. Local lumber yards stock replacement materials.
Customizable: Wood accepts stains and paints readily, allowing you to change colors as trends evolve.

Cons of Wood Decking in Pennsylvania
Maintenance Intensive: Our climate demands annual inspections and refinishing every 2-3 years. This includes:
Power washing
Sanding rough spots
Applying stain or sealant
Replacing damaged boards
Weather Vulnerability: Despite treatments, wood remains susceptible to:
Rot from moisture trapped under snow
Splitting from freeze-thaw cycles
Warping from humidity changes
Insect damage (carpenter ants are common in Monroe County)
Ongoing Costs: While cheaper initially, maintenance costs add up. Expect to spend $2-4 per square foot every few years on refinishing.
Composite Decking: The Modern Solution
Understanding Composite Materials
Composite decking combines wood fibers with plastic polymers, creating a material designed to overcome wood's limitations while maintaining its appeal.
Popular Brands Available in Pennsylvania:
Trex (most common)
TimberTech
Fiberon
Azek (PVC-based)
Pros of Composite Decking in Pennsylvania
Low Maintenance: The biggest advantage for busy Pennsylvania homeowners. Annual cleaning with soap and water is typically sufficient.
Weather Resistance: Engineered to handle our climate extremes:
Won't rot, warp, or split
Resists fading from UV exposure
Handles freeze-thaw cycles without damage
No splinters or rough surfaces over time
Longevity: Most manufacturers offer 25-year warranties, and composite decks often last 30+ years.
Consistent Appearance: No knots, grain variations, or natural defects. Color remains consistent across all boards.
Safety: No splinters make it ideal for families with children who play barefoot on decks.
Cons of Composite Decking in Pennsylvania
Higher Initial Cost: Expect to pay 2-3 times more than pressure-treated lumber upfront. However, this often balances out over the deck's lifetime when maintenance costs are considered.
Heat Retention: Composite materials can become uncomfortably hot during peak summer days, though newer formulations have improved this issue.
Limited Repair Options: Damaged boards often require replacement, and color matching can be challenging if the product line is discontinued.
Expansion and Contraction: While less than wood, composite still moves with temperature changes, requiring proper installation techniques.
Cost Comparison: 10-Year Analysis
Let me break down the real costs for a typical 300 square foot deck in Monroe County:
Wood Decking (Pressure-Treated)
Initial materials and installation: $3,000
Maintenance (years 2, 4, 6, 8, 10): $1,500
Total 10-year cost: $4,500
Composite Decking
Initial materials and installation: $7,500
Maintenance (minimal cleaning): $200
Total 10-year cost: $7,700
Performance in Pennsylvania Weather
Winter Performance
Wood: Requires snow removal to prevent moisture damage. Ice dams can cause significant problems. Composite: Handles snow load well, and ice won't cause rot. However, some expansion/contraction occurs.
Summer Performance
Wood: Can splinter and fade without proper maintenance. Staining required. Composite: May get hot but won't fade significantly. No maintenance required.
Spring/Fall
Wood: Prime time for maintenance tasks like cleaning and staining. Composite: Simple cleaning is sufficient.
Installation Considerations
Both materials require proper installation for optimal performance:
Drainage: Critical in our wet climate. Proper slope and ventilation prevent moisture issues. Fasteners: Stainless steel or hot-dipped galvanized fasteners resist corrosion in our humid environment. Spacing: Allows for expansion/contraction with temperature changes. Foundation: Proper footings below frost line (36" in Monroe County).
Environmental Impact
Wood: Renewable resource, but treatment chemicals and maintenance products have environmental impact. Composite: Often contains recycled materials, but manufacturing process is energy-intensive. Longer lifespan reduces replacement needs.
Making Your Decision: Key Questions
How long do you plan to stay in your home? If less than 10 years, wood might make financial sense.
How much time do you want to spend on maintenance? If you enjoy weekend projects, wood might appeal to you.
What's your budget situation? Can you handle higher upfront costs for long-term savings?
How do you use your deck? High-traffic areas with children might benefit from composite's splinter-free surface.
What's your aesthetic preference? Do you love the natural wood look, or do you prefer consistent appearance?
My Professional Recommendation
After building decks throughout Monroe County, I typically recommend:
Choose Wood If:
You're budget-conscious initially
You enjoy maintenance and DIY projects
You love the authentic wood aesthetic
You plan to move within 10 years
Choose Composite If:
You want minimal maintenance
You plan to stay long-term
You have young children
You want consistent appearance over time
Local Considerations for Monroe County
Building Codes: Monroe County requires permits for decks over 30" high. Both materials meet local building standards when properly installed.
HOA Restrictions: Some developments have material restrictions. Check before deciding.
Resale Value: Both materials add value, but composite's low maintenance appeals to many buyers.
Local Weather Patterns: Our specific microclimate in the Poconos can be harsh on materials. Professional installation is crucial for both options.
Conclusion
There's no universally "right" choice between composite and wood decking. The best material for your Pennsylvania home depends on your specific situation, priorities, and long-term plans.
What I can guarantee is that whichever material you choose, proper installation by an experienced local contractor familiar with Pennsylvania's climate challenges is essential for optimal performance and longevity.
