Wood is usually the lower-cost way to build a deck; composite usually costs more upfront but removes the recurring need to stain the deck boards. For a professionally built new deck in 2026, plan on roughly $25–$50 per square foot for pressure-treated wood, $30–$60 for cedar or redwood, and $30–$80 for composite. Premium materials, elevated framing, extensive stairs, railing, lighting, and difficult sites can exceed those ranges.
The right choice is not simply “cheap versus maintenance-free.” Wood offers authentic grain, repairability, and the option to change color. Composite offers more consistent boards, strong moisture resistance, and lower routine upkeep, but it can be hotter, harder to alter, and more expensive to replace if a discontinued color must be matched.

Wood vs Composite at a Glance
| Decision point | Wood decking | Composite decking |
|---|---|---|
| Installed cost | $25–$60 per sq. ft. for common treated wood, cedar, or redwood | $30–$80 per sq. ft. for most professional projects |
| Appearance | Natural grain and color variation; can be refinished | Consistent manufactured color and embossed grain; samples vary by collection |
| Routine care | Cleaning plus periodic stain or sealer as exposure requires | Sweeping and manufacturer-approved washing; no normal staining |
| Common concerns | Checks, splinters, decay, fastener staining, and finish upkeep | Heat, scratches, expansion rules, stains, and discontinued color matching |
| Best fit | Lowest initial budget or a homeowner who values real wood and refinishing | Lower board maintenance and a predictable factory-finished appearance |
These are Deck Cost Guide national planning ranges based on current material guides and installed-project benchmarks. Both options normally sit on structural framing, often pressure-treated lumber, so “composite deck” usually describes the walking surface—not the entire structure.
2026 Cost Comparison
| Decking choice | Typical installed range | What the range reflects |
|---|---|---|
| Pressure-treated wood | $25–$50 per sq. ft. | Value-oriented boards, conventional framing, and straightforward installation |
| Cedar or redwood | $30–$60 per sq. ft. | Species, grade, local supply, board profile, and finishing |
| Composite | $30–$80 per sq. ft. | Entry through premium capped boards, approved fasteners, fascia, and labor |
| Premium hardwood or PVC | $45–$90+ per sq. ft. | Premium boards, specialist installation, freight, and complex finishing |
The overlap matters. A simple entry-level composite deck may cost less than a complex clear-grade cedar design, while a premium composite with curved borders can cost far more than a basic treated-wood platform. Compare the complete design and bill of materials, not the price of one board.
Appearance and Design
Wood
Every board has its own grain, knots, and color. Cedar, redwood, and hardwoods offer visual depth that a printed or embossed surface cannot exactly reproduce. Wood can also be sanded and recolored, allowing an owner to change the look later. The tradeoff is natural variation, weathering, checking, and the need to manage moisture.
Composite
Current capped composite is available in many color blends, widths, grain patterns, and price levels. It stays more consistent than natural lumber, though batches can vary and screen images are unreliable. View full-length boards outdoors, in both sun and shade, before ordering. Plan borders and breaker boards carefully because many boards have a directional grain.
Maintenance and Cleaning
A wood deck needs periodic inspection, cleaning, and renewed protection as exposure and the chosen coating require. The schedule is not identical in every climate. Horizontal surfaces, pool decks, shaded areas, and high-traffic zones often need attention sooner. Delaying work until a coating fails can turn a maintenance coat into a more expensive stripping project.
Composite boards do not normally need stain or sealer, but “low maintenance” does not mean “no cleaning.” Leaves, pollen, food, grease, mildew growing on debris, and hard-water deposits can still mark the surface. Use the care guide for the exact brand and generation. Trex, for example, specifies soap, a soft-bristle brush, thorough rinsing, and limits for pressure-washer use on current product lines.
The substructure still requires inspection. A composite surface can outlast poorly detailed wood framing, so drainage, joist protection, ventilation, flashing, fasteners, and ledger connections matter whichever deck board you choose.
Durability and Service Life
Installation quality and moisture management are as important as the label on the board. Properly detailed and maintained wood can provide decades of service; neglected end grain, trapped debris, poor flashing, and ground contact can shorten that life. Individual wood boards are relatively easy to replace and refinishing can restore a weathered surface.
Composite boards resist rot and insect damage, and capped products improve stain and fade resistance. They can still scratch, become hot, expand and contract, or show localized damage. Replacement may be complicated if the manufacturer changes a profile or color. Keep spare full-length boards from the original batch when practical.
Heat, Slip Resistance, and Comfort
Any dark outdoor surface can become hot in direct sun. Color, cap material, air temperature, solar exposure, and airflow matter more than a blanket “wood versus composite” rule. Compare samples side by side at the time of day when the deck will be used. Lighter colors and shade can improve comfort.
Slip performance depends on texture, slope, contamination, wear, and water. Wood and composite both become slippery when algae, grease, leaves, or ice are present. Ask for current test information if wet-use performance is especially important, and plan drainage rather than relying only on board texture.
Environmental Considerations
There is no single environmental winner. Wood is renewable and can store carbon, but species, forestry certification, treatment, transport, coatings, service life, and replacement frequency matter. Composite often contains recycled material and can use waste streams, but it combines materials that may be difficult to separate at end of life.
Ask specific questions: Is the wood certified? What recycled content is documented? Can local facilities accept offcuts or old boards? How long is the expected service life in your application? A durable, correctly sized deck that is maintained and used for many years usually makes better use of resources than an oversized or prematurely replaced one.
Which Decking Is Best for Your Home?
- Choose pressure-treated wood when upfront cost is the main constraint and you accept periodic finishing.
- Choose cedar or redwood when natural appearance and workability matter, with availability and grade checked locally.
- Choose composite when lower board-maintenance is a priority and the higher initial budget is comfortable.
- Compare premium hardwood or PVC when longevity, a specific appearance, or a demanding exposure justifies specialist materials.
For any option, spend money first on sound footings, framing, ledger flashing, drainage, safe stairs, and code-compliant guards. A premium surface cannot compensate for a poor structure.
How to Compare Quotes Fairly
- Use the same plan, dimensions, elevation, footing assumptions, stairs, and railing in every quote.
- List the exact board manufacturer, collection, color, profile, length, and grade.
- Separate framing, decking, fasteners, fascia, railing, stairs, demolition, disposal, permits, tax, and labor.
- Confirm joist spacing, ventilation, drainage, blocking, flashing, and approved fastening details.
- Ask what waste allowance is included and whether spare boards remain with you.
- Read current installation and warranty documents before ordering.
- Compare at least two or three itemized contractor proposals.
Frequently Asked Questions
Is composite decking cheaper than wood over time?
It can be, but not automatically. Composite generally costs more upfront and avoids periodic board staining. The outcome depends on the chosen products, ownership period, local labor, wood-maintenance schedule, repairs, and whether either deck is installed correctly.
Does composite decking add more home value than wood?
Not necessarily. The latest national Cost vs. Value model showed strong resale recovery for both and a higher percentage for its standardized wood project. Buyers also respond to design, condition, usable space, neighborhood expectations, and local climate.
Can composite boards go over an old wood frame?
Possibly, after a documented inspection. The frame must be sound, correctly spaced, properly flashed, well drained, and suitable for current code and the selected manufacturer’s installation requirements.
Can wood be made as low-maintenance as composite?
No coating makes exterior wood maintenance-free. A well-chosen penetrating finish and timely renewal can simplify care, but wood still moves, weathers, and requires inspection.
Can composite decking be painted or stained?
Current capped composite normally should not be coated. Some older uncapped products have approved restoration methods. Ask the manufacturer to identify the board generation and permitted treatment before applying anything.
