Wood vs. Composite Decking: Which Is Actually Better for Your Home?
Pressure-treated lumber costs about half as much as composite per square foot. So why is composite outselling wood on most new residential decks? The answer isn’t what the salesperson tells you, and it isn’t what the lumber yard tells you either. Here’s the honest math on cost, lifespan, looks, and upkeep.
The Upfront Cost Nobody Disputes
Wood wins this round, and it isn’t close.
Here’s what you’ll actually pay installed (not just for materials sitting in your driveway):
- Pressure-treated pine: $15 to $25 per square foot
- Cedar or redwood: $20 to $38 per square foot
- Entry-level composite: $30 to $45 per square foot
- Premium capped composite or PVC: $40 to $60 per square foot
Put real numbers on it. A 300-square-foot deck in pressure-treated pine runs roughly $4,500 to $7,500. The same deck in mid-tier composite lands closer to $9,000 to $13,500. That gap has narrowed over the past few years as composite manufacturing scaled up, but it’s still substantial.
If your only filter is the sticker price, this article could end right here. But sticker price has a way of lying to you over twenty years.
The 20-Year Math Most Contractors Skip
This is the section that earns the article its place. If you like to know what something really costs before you commit, making the numbers a little more fun helps the long-term picture come into focus.
A pressure-treated deck needs to be sealed or stained every two to three years. That’s $300 to $600 per application, or a full weekend of your life. Over twenty years, that’s seven to ten cycles, plus likely board replacement around year ten to fifteen.
A composite deck needs cleaning. Occasionally. With soap and water.
Run the totals honestly:
- That $4,500 wood deck often becomes a $9,000 to $12,000 deck once two decades of upkeep are counted
- That $13,500 composite deck stays a $13,500 composite deck, and most quality composite decks carry 25 to 50-year warranties.
In humid climates or near pools, composite often wins on lifetime cost outright.
Climate should drive the material more than the showroom does. A clear comparison of decking materials helps you weigh the options against your conditions instead of the salesperson’s margin.
Maintenance Honesty
Brochures lie. Here’s what each material actually asks of you in real life.
Wood
- Annual walk-around to check for rot at the ledger board and post bases
- Power-washing and re-sealing every two to three years
- Sanding before re-staining once the finish has weathered hard
- Replacing popped nails, split boards, and the occasional rotten step
Composite
- A rinse twice a year
- Composite-safe cleaner for mildew on shaded sections (the most common complaint)
- Capped boards shrug off grease, red wine, and most spills
- Older, uncapped composites can fade and chalk, but capped products largely solved that
The honest take: composite isn’t maintenance-free. It’s maintenance-light. Wood isn’t impossible to keep up with. It’s just a recurring chore that homeowners consistently underestimate when they sign the contract. If you’re the type who already keeps a seasonal home maintenance checklist going, a wood deck slots in naturally. If your weekends are already spoken for, that matters too.
Looks, Feel, and the Things That Aren’t on a Spreadsheet
Some of this decision lives outside the math.
Wood smells like wood. It weathers to a silver patina if you leave it alone. Every board has its own grain, its own knots, its own small story.
Composite has gotten dramatically more convincing in the past five years (multi-tonal streaking, embossed grain patterns), but to anyone who knows what to look for, it still reads as not-quite-wood.
A few things worth knowing before you commit:
- Heat: Dark composite gets noticeably hotter underfoot in summer sun. If your deck takes the full afternoon, lighter composite or wood is kinder to bare feet.
- Feel: Wood is softer underfoot, which matters for kids and morning coffee in slippers.
- Aging: Wood ages with character if you let it. Composite stays close to the day you bought it for a decade or more.
There’s no objectively right answer here. The right answer depends on how your family will use the space.
Resale Value and HOA Considerations
Two practical things that catch homeowners off guard.
- Resale value: Remodeling Magazine’s annual Cost vs. Value report has historically shown that wood decks recoup a slightly higher percentage of their build cost than composite decks. Composite decks, however, are easier to market because buyers see “low maintenance” as a real selling point. The net effect in most markets is close to a wash.
- HOAs and neighborhood norms: Some HOAs restrict deck materials, board colors, or railing styles. In some upscale neighborhoods, a pressure-treated deck reads as builder-grade and works against the home’s curb appeal. Worth a quick check before you finalize the decision, not after. The same kind of upfront planning that goes into any major property project applies here, too: figure out the constraints before you fall in love with a design.
Matching the Material to How You Live
There’s no universally better material, only a better fit for your house, climate, and how much weekend time you’re willing to trade. Wood wins on upfront cost and warmth. Composite wins on long-term maintenance and the freedom to ignore it for years.The smartest move isn’t picking a material first. It’s about thinking through how the outdoor space will actually be used and working with a builder who walks you through the types of decks that fit your family. Pick the deck you’ll still love in fifteen years.
