Composite decking costs more up front but needs almost no maintenance and lasts 25+ years. Pressure-treated wood is cheaper initially but requires regular cleaning, sealing, and board replacement. Compare lifetime cost, not just the bid.

Upfront cost vs. lifetime cost
Wood almost always wins on the initial bid, and that is what makes the decision tricky. A pressure-treated deck can cost significantly less to build than a composite one of the same size.
But decking is a long-term investment. Over 15 to 20 years, the sealing, staining, and board replacement a wood deck requires can close much of that gap, and composite buys back a lot of weekends you would otherwise spend maintaining the deck.
Maintenance reality
This is where the two materials differ most. Composite typically needs only occasional washing. Wood needs regular cleaning and re-sealing to prevent rot, splintering, and graying, and boards will eventually need replacing.
- Composite: periodic washing, minimal upkeep
- Wood: annual or biannual cleaning and sealing
- Wood: expect to replace warped or split boards over time
How to decide for your home
If you plan to stay in the home long term and want to minimize upkeep, composite often makes sense. If budget is the priority or you enjoy maintaining a natural wood deck, treated wood is a legitimate choice.
Whichever you choose, the framing underneath matters more than the surface. A great composite board on a poorly built frame is still a bad deck.
Homeowner checklist
- Compare total cost over 15-20 years, not just the bid
- Factor in your tolerance for annual maintenance
- Confirm composite warranty terms and required certified install
- Ask about the framing and fasteners, not just the surface
- Consider how long you plan to stay in the home
Frequently asked
Is composite decking worth the extra cost?
For homeowners who want low maintenance and plan to stay in their home, composite often pays off over its lifespan. If budget is tight or you do not mind upkeep, quality treated wood is still a solid option.
Does composite decking get hot?
Composite can get warmer than wood in direct sun, especially darker colors. Lighter tones and good airflow under the deck help. It is worth discussing color choice with your builder.
