What’s the Average Composite Deck Cost in the US?
On average, the composite deck cost ranges between $25 to $45 per square foot, depending on the materials and whether you hire a professional or go DIY. Here’s a breakdown:
- DIY composite deck (12×12): $3,600 to $5,000
- Professionally installed (12×12): $5,500 to $7,500+
This price includes decking boards, framing, fasteners, and basic installation. Features like railings, lighting, or unique shapes can significantly increase the total project cost.
What’s Included in a Typical Composite Decking Estimate?
When you receive a quote from a contractor or supplier, it usually includes:
- Decking boards
- Substructure/framing
- Fasteners or hidden clips
- Labor/installation
- Waste disposal
- Permits (if needed)
What it doesn’t always include: railings, stairs, fascia boards, lighting, and post caps. Make sure to ask about these “extras” when comparing quotes.
What Factors Affect Composite Decking Costs?
There are several important variables that affect how much you’ll pay:
1. Deck Size and Layout
Larger decks need more materials, more labor, and more time. A simple square or rectangular design will cost less than one with curves, levels, or custom shapes.
2. Material Type and Brand
There are different grades of composite decking:
- Entry-level boards: $2–$4 per linear foot
- Mid-range: $5–$7
- Premium capped boards: $8–$12
Brands like Trex, TimberTech, and Fiberon offer a wide variety of products. Premium options tend to last longer, resist fading, and come with better warranties.
3. Solid vs. Hollow Boards
Solid composite boards are more durable but also more expensive and heavier. Hollow boards are lightweight and more affordable but may be less resistant to impact and wear.
4. Fastening Systems
Some composite boards require hidden fasteners, which add to both material and labor costs but provide a sleek, screw-free surface.
5. Labor Costs
Professional installation adds around $10–$20 per square foot. Labor costs can also vary based on your location and the complexity of your deck design.
Real-Life Budgeting Examples
Here are a few typical budgeting scenarios to give you a better sense of the total composite deck cost:
1. Small Deck (10×10 ft, 100 sq. ft)
- DIY: $2,500 to $3,500
- Pro install: $4,000 to $5,500
2. Mid-Size Deck (16×20 ft, 320 sq. ft)
- DIY: $7,500 to $10,000
- Pro install: $11,000 to $14,500+
3. Large Custom Deck (20×30 ft, 600 sq. ft)
- DIY: $13,000 to $18,000
- Pro install: $20,000+
These numbers vary depending on where you live, the brand you choose, and the features you add (like railings, built-in seating, or lighting).
Composite Decking Brand Cost Comparison
When it comes to choosing composite decking, brand matters—not just in looks and performance, but also in price. Here’s how some of the top brands stack up in 2025:
Deckorators
Deckorators is known for its mineral-based composite technology, offering increased strength and lighter weight. Pricing usually falls between $8 and $12 per sq. ft. depending on the line.
Trex
One of the most recognized names in composite decking, Trex offers a wide range of products. The Trex Enhance line starts around $6–$8 per sq. ft., making it one of the most affordable entry points. Higher-end lines like Trex Transcend can cost $10–$12+ per sq. ft. depending on color and finish.

Composite Decking Costs by Region
Location plays a huge role in pricing. Labor costs, material availability, and even climate can affect your total spend.
- Northeast & West Coast: Higher labor and material costs
- Midwest & South: More affordable materials and labor
- Rural areas: Lower labor rates but limited product selection
It’s a smart move to get at least 2–3 quotes from local contractors and compare brands available in your region.
How to Save on Composite Deck Cost
Looking to stay within budget? Here are a few tips that can help reduce your total project cost:
1. Choose a Simpler Design
Stick with a basic rectangular layout to avoid high labor and material costs tied to complex curves or multi-tiered platforms.
2. Do Some Work Yourself
Even if you’re not ready to build the whole thing, you can clear the site, pour the footings, or even help with framing.
3. Buy Materials During Off-Season
Prices tend to dip in late fall and winter. Many suppliers run seasonal promotions to clear inventory before spring.
4. Use Builder-Grade Options
You can still get quality results with entry- or mid-tier composite boards. Premium features are nice but not always necessary for a durable, attractive deck.
Is Composite Decking Worth the Price?
The composite deck cost might seem high at first glance, but the long-term value it provides in terms of low maintenance, durability, and lasting beauty makes it a worthwhile investment. Whether you’re doing a small DIY project or hiring a crew for a large build, understanding the cost factors upfront will help you stay on track and within budget.
