Cost factors of WPC deck include:

  • Composite deck texture – Usually composite deck manufacturers will have a variety of colors to choose from without additional cost, but if it is a custom texture or complex design and wood texture, special abrasive tools are required to increase the cost.
    The Ecoxplank manufacturer’s (ISO 9001 quality certified) deck costs nothing, and there is no additional cost for custom models.
  • Covered and uncovered WPC deck – Covered composite is a co-extruded composite deck, that is, the surface has a layer of high-density protective coating, anti-slip, higher waterproof strength, so the cost will be higher than the uncovered deck cost. For ground decks or light structures, hollow panels are a cost-effective choice, and solid panels should be preferred for elevated or two-story decks to ensure safety and durability.


    Cost variance:

    Covered material: $25-$32/ sq ft
    Materials without cover: $16-$20/ sq. ft

  • Solid with hollow WPC board: Hollow composite deck suitable for light weight pressure, if in public places will cause deformation. Solid deck panels are dense and structurally robust, making them suitable for high-load applications (such as elevated decks), but at a higher price.


    Cost variance:

    Solid board: $20-$28/ sq ft
    Hollow panel: $15-$22/ sq. ft

  • Fastener type – The hidden fasteners of today’s deck are more convenient and faster (refer to the best hidden firmware), and make the deck surface cleaner and safer. The cost of metal fasteners is higher than that of plastic fasteners, which can almost be ignored in the total cost.

    Cost variance:
    Traditional fasteners: $1-$2/ sq. ft
    Hidden fasteners: $3-$5/ sq. ft

  • Foundation and drainage systems— in rainy areas, priority is given to installing drainage systems to protect deck structures.
    Surface deck drainage system: Installation cost $1,000-$4,000, can effectively prevent moisture accumulation, avoid deck support structure rot.
    Elevated deck drainage system: Increase the drainage and downpipe system under the deck, suitable for the second deck, the cost is higher.

  • Gravel base Cost range: $0.85-$2.80 per square foot (including installation and material costs). Function: Prevent weed growth and promote rainwater drainage, suitable for elevated and second deck. Suitable for ground and elevated deck, long-term protection effect is good.

  • WPC deck foundation treatment in cold climates— Site survey before construction to accurately locate frost lines and reduce rework risks.
    Concrete feet: In cold areas, support columns must be installed below the frost line to ensure structural stability and prevent foundation movement.
    Cost impact: Increased excavation and concrete filling costs.

  • Add railings – Add wood railings or vinyl railings to the deck. It costs $20 to $60 per linear foot.

  • Installing stairs— Cost range: $20-$30/ linear feet (stairs themselves) + $80-$160 (concrete foundation). Length and complexity of stairs: Longer or guardrail stairs cost more. Purchase stairs together with deck materials to save transportation costs.

  • Foundation preparation and cost— Cost range: $500-$1,000 per yard/area.
    Mainly affected by land smoothness slope, ground or soft soil areas need additional reinforcement and filling work. There are also support systems: elevated or two-story decks require additional concrete or steel support structures. It is recommended to hire a professional installation team for on-site investigation to reduce the cost of later changes.

  • Geographical location and labor costs: Different geographical locations, labor costs are different, you can choose to flexibly choose the construction time, construction in the off-season with low labor costs (such as winter), while speeding up the construction progress.


    Cost variance:

    – Urban areas: Cost range: $50-$150 (depending on project size and regional policy).
    – Rural areas: Low demand, low labor costs, about $20-$35/ hour.

  • Permit fees and building regulations:
    Cost range: $50-$150 (depending on project size and district policy).
    Elevated or multi-deck decks require strict compliance with local building codes and permits must be applied for.
    License fees and approval times vary by region. Check with local authorities in advance to find out what permits and regulations are required.
    Prepare design drawings at the same time: Ensure that complete structural and safety assessment materials are submitted to speed up approval.
  • Design and structural engineering costs:
    Cost range: $100-$220/ hour (Structural engineer fee).
    Design complexity: Multi-deck or curved, staircase designs require professional engineering evaluation.
    Design drawings: Large areas or complex structures may require custom design, increasing design costs.
    Optimized design requirements: on the premise of meeting the function, simplify the structure and reduce the workload of engineers.
    Choose an experienced design team: complete the professional design once and avoid repeated modifications.

FAQ about laminate flooring

What is composite decking?

Laminate flooring is an environmentally friendly material that combines wood fiber with recycled plastic and is designed to replace traditional wooden decks. It combines the beauty of natural wood with the high durability of plastic, is resistant to moisture, rot and pests, and does not crack or deform easily.

The core advantages of laminate flooring are its low maintenance costs and long service life, making it ideal for outdoor terraces, pool decks and commercial Spaces.

Can you brad nail composite decking?

Nails (such as fine nails) cannot be used to fix composite decks because they do not have enough holding power, are prone to bending or breaking, and cannot effectively withstand the weight and environmental changes of the deck.

Instead, it is recommended to use specially designed deck hiding firmware screws that have better holding force to secure the screws to the hiding firmware and nail them into the keel of the deck and better accommodate the expansion and contraction of the composite material, ensuring the safety and durability of the deck. It can be used for decades without screws loosening.

How to clean composite decking?

Composite decks require almost no complex cleaning, just ordinary surface cleaning and water gun flushing, or you can follow our detailed composite deck cleaning process.

Regular cleaning: To clean a composite deck, first empty the deck of furniture and items, and then use a broom to sweep away loose dust and debris. Next, rinse the deck surface with warm water to better remove dirt. Then, mix warm water and mild dish soap in a bucket and use a soft brush to gently scrub the deck, making sure to clean along the grain to avoid scratching the surface. 

For stubborn stains, a mixture of vinegar and water can be applied topically. Finally, rinse the deck thoroughly with water to ensure there is no residual soap and dirt to keep its appearance fresh.

How long does composite decking last?

Composite decks typically have a service life of between 25 and 50 years, depending on the quality and maintenance of the material. High quality composite decks, when properly maintained, are resistant to decay, deformation and insect infestation, far exceeding the 5 to 15 year service life of traditional wooden decks.

Manufacturers like the Trex even offer up to 50 year warranties, further proving its durability and low maintenance needs.

Can you stain composite decking?

Ecoxplank is a famous professional deck manufacturer in China, we very much do not recommend to paint the composite deck, but this mainly depends on the type of deck. For older, unclad composite decks, coloring can be used. However, modern composite decks have PE cladding, a design that does not allow the stain to adhere effectively, and attempting to stain may void the warranty.

If you do plan to dye, it is recommended to use products designed for composite materials, such as ZAR Deck & Siding Solid Color Coating, which provide good adhesion and durability. Make sure to clean the deck thoroughly before dyeing for best results.

How to install hidden fasteners on composite decking?

To install concealed fasteners on the composite board, all necessary materials should be gathered at the beginning, including the composite board, concealed fasteners, starting clips, and standard woodworking tools.
See how to install hidden firmware.

Is composite decking slippery?

Not really. Much depends on the type of composite deck. Older generations with smooth surfaces are more likely to become smooth due to moisture, algae, and mold buildup, which can create dangerous conditions.

In contrast, second-generation composite paving products typically have textured surfaces and anti-slip properties that enhance grip and reduce slippage even in wet conditions. Ecoxplank has developed a third generation rubber coating, which is highly resistant to slip, and the wood grain is more realistic and durable.

Do you need a special blade to cut composite decking?

Yes, you need a special saw blade to cut laminate flooring effectively. It is recommended to use a fine-toothed hard diamond saw blade, especially one with about 80 teeth, as this type provides a good balance of speed and accuracy while minimizing splitting.

A circular or miter saw is the ideal tool for this task, and the use of a blade designed for composite materials ensures a clean and precise cut. In addition, Ecoxplank manufacturers recommend using a specific size of blade with a dense number of teeth to achieve smooth cutting without damaging the material (for cutting sections over 20cm, Ecoxplank will use a PCD diamond saw blade with 120 teeth at a cost of $630 per piece).

Will composite materials increase home values?

Yes, installing a composite deck can significantly increase the resale value of a home and is a high-return investment. According to the latest market data, the return on investment of composite deck projects is as high as 85%, and the average value of the home is about $15,000.
