Wood and composite decking each win at different things. Wood costs less upfront and looks warmer. Composite costs more upfront and lasts longer with no maintenance. The right choice depends on the home, the budget, and how you actually use the deck. Santos Replacement builds both across Pennsylvania and breaks down the trade offs honestly.
Key Takeaways
- Wood is cheaper to install, composite is cheaper to own over 25 years.
- Composite needs almost zero maintenance, wood needs sealing every 1 to 3 years.
- PA freeze thaw cycles are tougher on wood than composite.
- Composite hides into modern home designs better, wood fits traditional styles.
- Substructure is wood under both, only the visible boards differ.
Upfront Cost in Pennsylvania
For a 300 square foot deck installed:
- Pressure treated pine: $4,500 to $8,500
- Cedar: $7,000 to $13,000
- Ipe or other hardwood: $14,000 to $22,000
- Capped composite (mid range): $9,000 to $16,000
- Premium composite (Trex Transcend, TimberTech AZEK): $14,000 to $22,000
- PVC decking: $15,000 to $24,000
Pressure treated wood is the cheapest entry point. Premium composite costs roughly twice as much. Hardwood and PVC sit at the top.
25 Year Total Cost of Ownership
This is where composite wins. Over 25 years on the same 300 square foot deck:
- Pressure treated wood: $4,500 install plus $200 per year sealing and minor repairs plus board replacement around year 15 = roughly $11,000 to $14,000 total
- Cedar: $9,000 install plus $250 per year maintenance plus partial reboard around year 18 = roughly $15,000 to $18,000
- Capped composite: $13,000 install plus near zero maintenance plus no replacement = roughly $13,500 to $14,500
Composite breaks even with pressure treated wood around year 15 and beats it thereafter.
Maintenance in Pennsylvania Weather
PA decks face freeze thaw cycles 30 to 60 times per winter, summer humidity, and heavy spring rain. Wood requires:
- Annual cleaning with a deck wash
- Re sealing or staining every 1 to 3 years
- Sanding splinters as boards weather
- Replacing rotted boards typically by year 10 to 15
Composite requires a rinse with a garden hose twice a year. That is the entire maintenance routine.
Lifespan of Each Decking Material
Pressure treated wood: 15 to 25 years for the deck boards, longer for the substructure if treated properly. Cedar: 20 to 30 years. Hardwood: 30 to 50 years. Capped composite: 25 to 30 years. PVC decking: 30 to 50 years.
Manufacturer warranties: composite typically carries 25 to 50 year fade and stain warranties. Wood carries no comparable warranty on the boards themselves.
Looks and Resale
Wood is warmer and more natural. New pressure treated lumber starts greenish from the chemical treatment, weathers to gray within a year, and accepts stain to almost any color.
Composite has improved dramatically. Premium lines mimic exotic hardwoods with grain patterns and multi tone colors that pass for real wood from 10 feet away. Up close composite still looks composite, but on a finished deck it integrates well with most home exteriors.
For resale, both materials add value. Composite slightly outperforms wood at sale because buyers know they will not have to seal it.
Heat in Direct Sun
Composite gets significantly hotter than wood in direct PA summer sun. Dark composite boards on a south facing deck can reach 150 degrees on a 90 degree day, hot enough to burn bare feet. Choose lighter colors, add shade, or stick with wood if the deck gets full afternoon sun.
Environmental Considerations
Pressure treated wood uses copper based preservatives, safer than older arsenic treatments but still chemically treated. Cedar is naturally rot resistant, harvested from managed forests. Composite is typically 50 to 95 percent recycled plastic and wood fiber. Each has a story, none is clearly best on environmental grounds.
What We Recommend for Pennsylvania Homes
For a budget deck that will last 15 years and accept ongoing maintenance: pressure treated wood. For a small to medium deck where maintenance is the deal breaker: capped composite. For a high end home with traditional architecture: cedar or hardwood. For pool decks, dock decks, or anything close to water: PVC.

Frequently Asked Questions About Wood vs Composite Decking
Does composite fade in PA sun?
Modern capped composite resists fading for 20 plus years. Older uncapped composite faded badly, the technology has improved significantly since 2015.
Can I install composite over my existing wood deck?
Only if the substructure is sound. Composite is heavier than wood and requires joist spacing per the manufacturer (usually 16 inches on center, sometimes 12).
Is composite slippery when wet?
Some early composite was slippery. Modern textured surfaces and embossed wood grain patterns provide grip comparable to wet wood.
Will composite swell or rot?
Capped composite resists moisture penetration. Uncapped older composite could absorb water at the edges and warp, capped composite eliminates that issue.
Which is easier for a DIY installer?
Wood is more forgiving of small mistakes. Composite requires precise fastener placement and specialized clips, but is not difficult with manufacturer instructions.
