Composite vs. Wood Decking: Which Costs More?
Compare wood and composite decking costs, maintenance, lifespan, and other factors to consider before choosing a material for your new deck.
September 16, 2026
Composite decking costs more per square foot than pressure-treated wood. That part is simple. The harder question is what each surface costs you over the years you actually own it — and which one fits the way you want to spend your weekends.
Up-front cost
Pressure-treated pine is the least expensive decking surface and the most widely available. Cedar and redwood cost more and bring a warmer look with natural rot resistance. Capped composite costs more again, and PVC generally sits at the top.
Keep in mind that only the walking surface changes when you switch materials. The framing, footings, and labor underneath are largely the same, so upgrading the surface raises the total by less than the per-board price difference suggests.
Maintenance is the real difference
A wood deck wants cleaning every year and stain or sealer roughly every two to three years, depending on sun and weather exposure. That is either a weekend of your time or a recurring line item from a contractor.
Composite and PVC need washing and little else. No stain, no sealer, no sanding out splinters. Over a fifteen-year span, that maintenance gap frequently closes much of the up-front cost difference.
Lifespan and appearance over time
- Pressure-treated wood: roughly 10 to 20 years with consistent maintenance; can warp, crack, and splinter
- Cedar: similar lifespan with a finer appearance; softer and more prone to dents
- Composite: commonly 25 to 30 years; resists rot and insects, can fade slightly, gets warm in direct sun
- PVC: longest service life and lightest weight; the most manufactured look of the group
How to decide
Choose wood if the up-front budget is the binding constraint, you like the natural look, or you expect to move within a few years. Choose composite or PVC if you want to stop maintaining the deck, you have a large surface where annual staining would be a real chore, or you are building a pool deck or a shaded area where wood struggles.
Also weigh the color and railing options. Composite systems pair with matching railings and hidden fasteners for a cleaner finished look, which matters on a deck that is the focal point of the backyard.
