What is Composite Wood Decking?
Before diving into the cost breakdown, it’s important to understand what composite wood decking is. Composite decking is made from a blend of wood fibers and plastic (usually PVC or polyethylene). The result is a material that mimics the look and feel of real wood but with added durability and minimal upkeep. Composite decking from Hosung comes in a variety of colors, textures, and styles, offering plenty of design options for homeowners.
While composite decking has been around for decades, advances in technology have significantly improved its appearance and longevity, making it a preferred choice for homeowners who want the aesthetics of wood with far less maintenance.

Cost Breakdown of Composite Wood Decking
The cost of installing a composite wood deck is generally broken down into the following key categories:
a) Materials Cost
This is the primary component of the total cost of composite decking and accounts for a significant portion of the overall expenditure. The materials cost includes:
- Decking Boards: The most expensive part of the materials cost. Decking boards come in various sizes, colors, and textures. Premium brands with advanced features, like scratch resistance or enhanced durability, can cost more.
- Railing Systems: Composite railings are often included in the material cost and can be either integrated or separate from the decking boards. Like the decking, railings come in a variety of styles and finishes.
- Fasteners and Clips: Special fasteners and clips are used to secure the decking boards to the substructure. Some high-end composite decking systems use hidden fasteners, which are more expensive but provide a seamless look.
- Underdecking: Underdecking is an optional feature that helps to protect the area beneath the deck from weather damage. It also improves the overall appearance by concealing joists and framing. Underdecking systems can add to the materials cost.
b) Labor Cost
Labor costs can vary greatly depending on the complexity of the deck design, location, and the contractor you hire. On average, the labor cost for installing composite decking is higher than that of traditional wood decks because of the precise installation required for composite materials.
Labor costs will be influenced by:
- Deck Size and Complexity: Larger, more intricate decks will require more time to install, increasing labor costs. A simple rectangular deck will generally cost less to install than a multi-level or custom-shaped deck.
- Region: Labor rates can vary depending on your geographic location. Urban areas tend to have higher labor costs than rural areas, and the cost of living can influence pricing as well.
- Decking Brand and Type: Some composite brands require special installation techniques or tools, which could also drive up labor costs.
c) Permits and Inspections
In many areas, building permits are required for installing a new deck, especially if the deck is over a certain size or height. The cost of these permits varies by locality but typically ranges from $50 to $500 or more, depending on the complexity of the deck and local regulations.
d) Additional Features
Composite decks can include several additional features that increase the overall cost:
- Lighting: Outdoor lighting, such as recessed lights in the steps or railings, can add beauty and safety to the deck. The installation of lighting can add $500 to $1,500 or more to the overall project cost.
- Built-in Seating or Planters: If you choose to incorporate built-in features like seating, storage, or planters, these will add to the cost, as they require additional materials and labor.
- Covering or Gazebo: A deck covering or gazebo can transform your deck into an all-weather space, but they significantly increase the cost. A basic roof structure can add several thousand dollars to the project, depending on the materials used.

Factors That Affect Composite Decking Costs
Several factors can influence the cost of composite decking, making it important to carefully evaluate your options before making a purchase.
a) Brand and Quality
The brand you choose for your composite decking will have a significant impact on the cost. High-end composite decking brands like Trex, TimberTech, and Azek are known for their durability, aesthetic appeal, and advanced features, but they tend to be more expensive than budget options. Premium brands may also come with longer warranties and additional features, like enhanced scratch resistance, making them a better long-term investment.
b) Type of Composite Decking
Composite decking comes in two main types: solid and hollow. Solid composite boards are more durable and often more expensive, while hollow boards are lighter and cost less but may be less durable in the long term. Additionally, composite decking comes in two styles:
- Capped Composite Decking: Capped composite decking has a protective outer layer, making it resistant to moisture, mold, and fading. Capped boards are generally more expensive than uncapped boards but offer better protection and longevity.
- Uncapped Composite Decking: These decks do not have a protective outer layer, which means they may require more maintenance and are more prone to damage from UV rays and moisture. They are typically less expensive than capped boards.
c) Color and Finish
Composite decking is available in a wide variety of colors and finishes, and the style you choose will impact the price. Custom colors or textures may come at a premium, and boards with intricate patterns or wood-like finishes may be more expensive.
d) Thickness of the Decking
The thickness of composite decking boards can influence both the cost and durability of the deck. Thicker boards are more durable but tend to be more expensive. Thinner boards, while cheaper, may wear out more quickly and require more maintenance.
e) Local Material Availability
In regions where composite decking is less common, transportation costs for materials can increase the overall price. Shipping costs can be especially high for larger projects, and prices may vary based on the proximity of your supplier.
f) Environmental Factors
Some composite decking materials are made with recycled content, which can affect the cost. Decking with higher amounts of recycled materials may cost slightly more, but these products are often marketed as eco-friendly, and their use can contribute to reducing waste.

Cost Comparison: Composite Decking vs. Traditional Wood Decking
When considering the cost of composite wood decking, it’s useful to compare it to the cost of traditional wood decking. While composite decking is typically more expensive upfront, it offers a number of long-term advantages that may make it a more cost-effective choice over time.
Initial Cost
Composite decking can cost anywhere from $5 to $13 per square foot, depending on the quality and brand. In comparison, pressure-treated wood decking generally costs between $2 to $6 per square foot, while high-end wood options like cedar or redwood can cost $6 to $12 per square foot.
Maintenance Costs
One of the biggest advantages of composite decking is its low maintenance. Traditional wood decks require regular sealing, staining, and painting to maintain their appearance and prevent deterioration. This can add up to several hundred dollars per year in maintenance costs. Composite decks, on the other hand, only require occasional cleaning, saving you money in the long run.
Lifespan
Composite decking typically lasts 25-30 years, while wood decking may only last 10-15 years, depending on the type of wood and the amount of maintenance it receives. This extended lifespan of composite decking can make it a more cost-effective option in the long term.

Estimating Total Composite Decking Costs
To estimate the total cost of your composite wood deck, you should consider:
- Deck Size: Measure the square footage of the area you want to cover. Larger decks will naturally cost more in terms of both materials and labor.
- Location: Geographic location affects both material and labor costs, so it’s important to consider local pricing.
- Design Complexity: Simple, rectangular decks are the least expensive to build. Adding features like stairs, multi-level platforms, or curves will increase both material and labor costs.
- Additional Features: Features like built-in seating, planters, or lighting will add to the overall price.
- Material Selection: Choose between different types of composite boards, finishes, and colors based on your aesthetic preferences and budget.
Conclusion
Composite wood decking provides an excellent solution for homeowners seeking a durable, low-maintenance, and aesthetically pleasing outdoor space. While the initial cost of composite decking may be higher than traditional wood decking, its long lifespan, minimal maintenance needs, and high durability make it a worthwhile investment. Understanding the factors that influence the cost of composite decking can help you make an informed decision and find the right balance between budget and quality for your project.
By considering your specific needs, such as deck size, location, design preferences, and the types of materials and features you prefer, you can get a better sense of the total cost involved in installing a composite wood deck.
