The True Cost of Outdoor Living: Wood vs. Composite Decking
Planning a deck? We break down the upfront costs and long-term maintenance of Pressure Treated Pine vs. Composite (Trex/TimberTech). Learn about permit fees, footing requirements, and railing options.
A deck extends your living space into the outdoors, increasing home value and quality of life. But the material choice—Wood or Composite—divides homeowners. Wood is cheap to buy but expensive to own (staining, sealing). Composite is expensive to buy but cheap to own (soap and water).
Material Contender 1: Pressure Treated (PT) Pine
The standard green-tinted wood found at every lumber yard. It is chemically treated to resist rot and termites.
- Pros: Lowest upfront cost ($15-$25/sq ft installed). Natural look.
- Cons: Warps, twists, and cracks over time. Splinters. Requires annual pressure washing and staining.
Material Contender 2: Composite (Trex, etc.)
A blend of recycled plastic and wood fibers, capped with a durable polymer shell.
- Pros: Zero rot, zero splinters, zero staining. Consistent color. 25-year warranties.
- Cons: High upfront cost ($35-$60/sq ft installed). Can get hot in direct sun. Cannot be sanded if scratched.
The Invisible Costs: Structure and Railing
Regardless of the decking boards, the frame is usually PT Lumber. You must dig footings below the frost line (labor intensive) and install concrete piers. The railing is another budget shocker. A simple wood railing is cheap; aluminum or cable railing can cost more than the deck boards themselves.

The Break-Even Point
Composite costs about 40% more upfront. However, factoring in the cost of stain/sealer and your labor every year, the break-even point is usually around year 5-7. If you plan to stay in the house longer than 5 years, composite often wins financially.
