Composite decking costs between $5 and $18 per square foot for materials alone, with total installed costs (including substructure, labor, and materials) typically landing between $25 and $50 per square foot. For a standard 300-square-foot deck, that means you're looking at roughly $7,500 to $15,000 all in. The final number depends on the type of composite material you choose, your deck size, the complexity of your deck design, and whether you hire deck contractors or handle the build yourself.
If you've been comparing deck pricing and feeling a bit of sticker shock, you're not alone. Composite decking costs more upfront than pressure treated wood. But before you default to traditional wood decking, it's worth understanding what you're actually paying for and where the real savings show up over a 25-year lifespan.

What Drives Composite Deck Cost? The Key Cost Factors
You'll see composite decking prices per square foot quoted anywhere from $5 to $18 for materials. That's a wide range, and it confuses a lot of people. The spread exists because "composite decking" isn't one product. It's a category with multiple material types, board profiles, quality tiers, and brand positioning strategies.
Here are the cost factors that actually move the needle on your deck project budget.
Deck Size and Layout Complexity
The size of your deck is the single biggest cost driver. A simple rectangular 200-square-foot ground-level deck costs far less than a 400-square-foot multi-level design with angles, curves, and built-in seating. Every extra cut, corner, and level adds material waste and labor time.
Ground-level platform decks (under 30 inches high) are the most affordable to build because they often don't require railing by code and use simpler footings. Elevated decks, wrap-around designs, and decks with stairs cost significantly more due to structural requirements.
Types of Composite Decking Materials
Not all composite deck boards use the same core material, and this distinction has a direct impact on both price and long-term performance.
Wood-plastic composite (WPC): The most common type. Blends recycled wood fibers with plastic polymers. Brands like Trex and TimberTech fall in this category. Material cost typically ranges from $5 to $14 per square foot. The wood fiber content makes these boards more affordable but also more susceptible to moisture absorption over time.
Rice-husk composite: Uses rice husks instead of wood fibers. This matters more than most people realize. Rice husks absorb less moisture than wood fibers, which means the boards resist rotting and molding at a fundamental level. They also offer superior fire resistance compared to wood-based composites. TruNorth Composites is the leading manufacturer in this category, with composite decking materials that contain zero wood content and 95% recycled material. Pricing is competitive with mid-range to premium wood-plastic composites.
Mineral-based composite: Uses natural minerals bonded with polymer resin instead of wood fibers or rice husks. Millboard is the leading brand in this category, combining a fiber-reinforced mineral stone core with a proprietary Lastane elastomeric surface layer that is hand-molded from real oak timber. The result is a board that is completely impervious to moisture, won't rot or warp, and delivers arguably the most realistic wood-grain appearance on the market. Material costs typically range from $12 to $20+ per square foot, placing mineral-based composites at the premium end of the pricing spectrum. Manufactured in the UK with U.S. distribution.
PVC decking: Made entirely from synthetic materials with no organic content. PVC decking costs roughly $5 to $15 per square foot for materials. It offers maximum moisture resistance, which makes it popular for waterfront applications. Clubhouse, a sister brand of TruNorth, manufactures premium PVC decking options.
Composite Deck Board Profile: Solid Core vs. Hollow
Composite deck boards come in two main profiles, and this choice affects both your material cost and how the deck performs.
Solid core boards (like TruNorth Accuspan) are denser and heavier. They feel more substantial underfoot, resist impact better, and are the preferred choice for high-traffic areas and new deck construction. They cost more per square foot.
Hollow core boards (like TruNorth Enviroboard) are lighter and easier to handle. They use the same capping technology and come in the same colors, but the hollow profile reduces material cost. They're an excellent choice for budget-conscious projects, renovations, and DIY deck installation where lifting and cutting heavy boards all day gets tiring fast.
Both profiles from TruNorth feature 4-sided capping with rice-husk technology and carry the same 25-year product, fade, and stain resistance warranty. The choice between them comes down to budget and application, not quality.

A note on these numbers: material costs fluctuate by region, retailer, and time of year. The ranges above reflect 2025/2026 national averages for deck board materials only (not substructure, fasteners, or trim). Always get current quotes for your specific project.
One factor that separates TruNorth from most competitors: it's manufactured in Brantford, Ontario, Canada, with a distribution center in Tallmadge, Ohio. CompositeDeckDirect ships factory-direct, which can mean meaningful savings compared to buying through a big-box retailer. That's something worth exploring if you're building a new composite deck and want to stretch your budget without downgrading your deck material.
Installation Costs: DIY vs. Professional Deck Contractors
Labor costs are where deck pricing gets unpredictable. Professional installation typically runs $10 to $20 per square foot for a standard ground-level composite deck. Elevated decks, multi-level builds, and complex designs can push labor to $25 or more per square foot.
For a 300-square-foot deck, that means labor alone could run $3,000 to $6,000 or more. That's a significant chunk of your overall cost.
DIY installation eliminates the labor line item entirely, which can cut your total project cost by 30% to 50%. Composite decking is actually well-suited for DIY because most brands (including TruNorth) are compatible with standard woodworking tools and offer hidden fastener systems like Slide & Go clips that simplify the process.
If you go the professional route, get at least three quotes from licensed and insured deck contractors. Labor costs vary dramatically by region and even between contractors in the same city. The cheapest bid isn't always the best choice. Ask about their experience with composite materials specifically, because installing composite decking requires different techniques than traditional wood.
Additional Costs That Affect Your Deck Project Budget
The deck boards themselves are only part of the total cost. Here are the additional costs that catch people off guard.
| Cost Category | Typical Range | Notes |
| Substructure / framing | $5 - $15 per sq ft | Pressure treated wood joists, beams, posts, concrete footings |
| Railing | $20 - $60 per linear foot | Composite, aluminum, or cable railing. Required for decks over 30" |
| Stairs | $1,400 - $2,600 installed | Per staircase. Cost rises with number of steps |
| Fasteners & clips | $0.50 - $1.50 per sq ft | Hidden fastener systems cost more but look cleaner |
| Fascia & trim | $2 - $6 per linear foot | Finishing boards that cover exposed framing and edges |
| Permits | $225 - $500 | Required in most municipalities. Check local codes |
| Old deck demolition | $5 - $15 per sq ft | If replacing an existing deck. Adds $1,500 - $4,500 for a 300 sq ft deck |
| Grading / site prep | $500 - $1,000 | Leveling ground, drainage, gravel base |
When budgeting for your new composite deck, add 10% to 15% to your calculated total for contingencies. Surprises happen: rotted joists on an existing deck, unexpected grading needs, permit delays. A buffer keeps you from making cost-cutting decisions mid-project that you'll regret.
Composite Decking vs. Wood Deck: A Real Cost Comparison
The upfront cost of composite decking materials is higher than traditional wood decking. Pressure treated wood runs $3 to $6 per square foot for the boards alone. Cedar and redwood land between $7 and $12 per square foot. Composite deck boards start around $5 and range up to $18 per square foot depending on type and brand.
That initial cost gap is real. On a 300-square-foot deck, you might save $600 to $2,400 on materials by choosing pressure treated wood over a mid-range composite. But that's where the savings story for natural wood decks ends.
25-Year Total Cost of Ownership
Wood decks require annual maintenance that adds up fast. Staining, sealing, sanding, and replacing warped or rotted boards cost $300 to $800 per year for a typical deck. Over 25 years, that's $7,500 to $20,000 in maintenance alone. And most wood decks need partial or full replacement after 10 to 20 years.
Composite decking? Soap and water. That's the maintenance. The lifespan of composite decking runs 25 to 50 years depending on the product, and you won't spend a dollar on stain, sealant, or board replacement during that time.
| Cost Category | Pressure Treated Wood | Mid-Range Composite | Premium Composite |
| Material cost (300 sq ft) | $900 - $1,800 | $2,100 - $3,600 | $3,000 - $5,400 |
| Installation labor | $2,400 - $4,200 | $3,000 - $6,000 | $3,000 - $6,000 |
| Substructure & extras | $2,500 - $4,500 | $2,500 - $4,500 | $2,500 - $4,500 |
| Annual maintenance (x25 yrs) | $7,500 - $20,000 | $0 - $250 | $0 - $250 |
| Replacement (years 12-15) | $3,000 - $6,000 | $0 | $0 |
| 25-Year Total Cost | $16,300 - $36,500 | $7,600 - $14,350 | $8,500 - $16,150 |
Read that bottom row again. The "cheap" option costs nearly double over 25 years when you account for maintenance and replacement. This is why composite decking costs less in the long run, even though the initial investment is higher.
Products like TruNorth Accuspan and Enviroboard back this up with 25-year warranties covering the product itself, fade resistance, and stain resistance. The rice-husk formula (zero wood content) means the core material won't rot or mold, which is the failure mode that kills most wood decks and even some wood-based composites.
How to Reduce Composite Decking Costs Without Cutting Corners
The goal isn't to find the cheapest composite deck boards. It's to get the best long-term value at a price you can afford. Here's how to build your dream deck without blowing the budget.
- Buy factory direct. Purchasing composite decking materials from a manufacturer-direct retailer like CompositeDeckDirect can save up to 20% compared to big-box store pricing. You get the same product, same warranty, better price.
- Choose the right profile for your project. If you're building a low-traffic deck or doing a renovation, TruNorth Enviroboard (hollow core) gives you the same capping and color options as the solid-core Accuspan at a lower per-square-foot material cost.
- Keep the design simple. A rectangular deck with minimal corners uses materials more efficiently and reduces labor costs. Save complex angles and curves for areas where they create real visual impact.
- DIY what you can. Even if you hire a contractor for framing and structural work, installing the deck boards yourself can save thousands. Hidden fastener systems make this more accessible than you'd think.
- Order free samples first. Test colors in your actual outdoor space before committing. A color that looks great online might not work with your home's siding or landscaping. Reordering because of a color mismatch is an expensive mistake.
- Build in the off-season. Deck contractors are busiest from April through July. Scheduling your deck build for late fall or early spring can mean lower labor costs and better contractor availability.
Sample Deck Budgets: What Your Composite Decking Project Will Actually Cost
Here's what real deck builds look like when you add everything up. These estimates assume a ground-level rectangular deck with standard railing on three sides, a single staircase, hidden fasteners, and professional installation.
| Component | 200 sq ft Deck | 300 sq ft Deck | 400 sq ft Deck |
| Composite deck boards (mid-range) | $1,400 - $2,400 | $2,100 - $3,600 | $2,800 - $4,800 |
| Substructure / framing | $1,000 - $3,000 | $1,500 - $4,500 | $2,000 - $6,000 |
| Railing (3 sides) | $1,200 - $3,000 | $1,500 - $3,600 | $1,800 - $4,200 |
| Stairs (1 set) | $1,400 - $2,600 | $1,400 - $2,600 | $1,400 - $2,600 |
| Fasteners, fascia, trim | $300 - $600 | $450 - $900 | $600 - $1,200 |
| Permits & site prep | $725 - $1,500 | $725 - $1,500 | $725 - $1,500 |
| Labor (professional install) | $2,000 - $4,000 | $3,000 - $6,000 | $4,000 - $8,000 |
| Estimated Total | $8,025 - $17,100 | $10,675 - $22,700 | $13,325 - $28,300 |
These ranges are wide because deck pricing depends heavily on your region, your chosen brand, and your deck design. A homeowner in the rural Midwest will pay significantly less for labor than someone in a major metro area. The type of composite decking you select (wood-plastic vs. rice-husk vs. PVC) also shifts the material line item.
For a tighter estimate, start by choosing your deck board (request free samples from CompositeDeckDirect to compare options), measure your deck area, and get three contractor quotes. That process narrows a $9,000 range into a reliable number you can plan around.
Frequently Asked Questions About Composite Deck Pricing
How much does composite decking cost per square foot?
Composite decking materials cost between $5 and $18 per square foot depending on the type (wood-plastic, rice-husk, or PVC), brand, and board profile. Total installed cost, including substructure and labor, typically ranges from $25 to $50 per square foot.
Q: Is composite decking more expensive than wood?
Yes, the upfront cost is higher. Composite materials run $5 to $18 per square foot compared to $3 to $6 for pressure treated wood. But composite decks last 25 to 50 years with virtually zero maintenance, while wood decks require $300 to $800 per year in upkeep and typically need replacement after 10 to 20 years. Over 25 years, a composite deck costs significantly less than a wood deck.
Q: What is the most affordable way to build a composite deck?
Buy materials factory direct (saves up to 20% over retail), choose a hollow-core profile like TruNorth Enviroboard, keep the design simple and rectangular, and handle the deck board installation yourself using hidden fastener clips. These steps combined can reduce your total composite deck cost by 30% to 40% compared to a contractor-installed premium build.
Q: How much does a 20x20 composite deck cost?
A 400-square-foot composite deck typically costs $13,000 to $28,000 installed, depending on the brand, region, and complexity. Materials alone run $2,800 to $7,200. If you DIY the installation and buy direct, you can potentially bring the total closer to the $10,000 to $16,000 range.
Q: What is the difference between wood-plastic composite and rice-husk composite?
Wood-plastic composites blend recycled wood fibers with plastic polymers. Rice-husk composites (like TruNorth) replace wood fibers entirely with rice husks. The practical differences: rice-husk composites contain zero wood content, which eliminates rotting and molding at the material level. They also offer superior fire resistance and absorb less moisture. Both types are fully capped and carry similar warranties.
Q: How long does composite decking last?
Most quality composite decking lasts 25 to 50 years. TruNorth composite decking carries a 25-year warranty covering the product, fade resistance, and stain resistance. The actual lifespan often exceeds the warranty period because composite materials don't suffer from rot, insect damage, and warping that limit natural wood decks to 10 to 20 years.
Q: Does composite decking add value to your home?
Yes. A well-built composite deck can recoup 60% to 70% of its cost in home value at resale, and the low-maintenance appeal is a strong selling point for buyers. Compared to a deteriorating wood deck that needs work, a composite deck in good condition is a clear home improvement advantage.
Q: What additional costs should I budget for beyond deck boards?
Plan for substructure/framing ($5 to $15 per square foot), railing ($20 to $60 per linear foot), stairs ($1,400 to $2,600 per set), fasteners and trim ($0.50 to $1.50 per square foot plus $2 to $6 per linear foot for fascia), permits ($225 to $500), and potentially old deck demolition ($5 to $15 per square foot). Add a 10% to 15% contingency buffer.
