Labor costs for building a 20×20 composite deck
Labor costs for building a 20×20 composite deck can vary depending on the complexity of the project. Hiring professionals to construct your dream outdoor space is a smart investment that ensures quality workmanship and a durable deck that will last for years to come. Here are three factors that can influence labor costs:
1.Deck Design: The complexity of your deck design plays a significant role in determining labor costs. Intricate designs with multiple levels, curves, or custom features require more time and expertise to build, resulting in higher labor charges.
2.Site Preparation: Before construction begins, proper site preparation is necessary to ensure a solid foundation for your deck. Factors such as grading, clearing vegetation, or removing existing structures can add to the overall labor costs.
3.Decking Installation: Composite decking materials often require specialized installation techniques compared to traditional wood boards. Labor costs may be higher due to the extra steps involved in cutting and fitting composite boards precisely.

Tips for minimizing costs during the construction process
One way you can minimize costs during the construction process is by carefully planning your design and materials. By doing so, you can avoid unnecessary expenses and make the most of your budget. Here are some tips to help you save money when building a 20×20 composite deck.
-
- Consider the layout and design of your deck. Opting for a simple rectangular shape will be more cost-effective compared to complex designs with multiple levels or curves. Additionally, keeping the size of your deck within standard dimensions will help reduce waste and cut down on material costs.
-
- Do thorough research on different composite decking materials available in the market. Look for options that offer a good balance between quality and affordability. Compare prices from various suppliers to ensure you get the best deal possible.
-
- Consider using recycled or salvaged materials for certain aspects of your deck. For example, using reclaimed wood for railings or furniture can add a unique touch while also being cost-effective.
-
- Don’t forget to obtain multiple quotes from different contractors before making any final decisions. This will allow you to compare prices and negotiate better deals based on your budget.
Discover Different Outdoor Deck Types
Ground-Level Decks:
Perfect for a cozy outdoor retreat, ground-level decks are usually under 36 inches high and attached to the house near a back door. They can be equipped with railings for added safety. Costs may vary depending on the number of steps and any required foundation work.
Freestanding Decks:
These versatile decks rest on the ground using dirt and concrete blocks, eliminating the need for deep footings. With no railings or stairs required, they offer a straightforward installation. In many places, permits aren’t necessary since they aren’t connected to the house.
Elevated Decks:
Positioned at least three feet above the ground, elevated decks are typically found under a second story. Built on a solid concrete foundation, they must have railings for safety and compliance with building regulations, adding both security and style.
Second-Level Decks:
Great for creating shaded spots, these decks are raised above ground level and supported by sturdy columns. They provide a comfortable outdoor area to enjoy the breeze while staying cool.
Multi-Level Decks:
Ideal for multi-story homes, these decks consist of connected outdoor spaces perfect for entertaining and activities. While they can be the most expensive option, they offer an expansive and dynamic outdoor area for all to enjoy.
Factors Affecting the Cost of Installing Composite Decking
Labor costs to build composite decking are higher than wood decks because they require more care in assembly and have more parts. Typically, the labor cost to hire someone to install composite decking ranges from $24 to $48 per square foot.
| Factor | Cost per square foot* |
|---|---|
| Materials | $16 – $32 |
| Labor | $24 – $48 |
| Total cost to install | $40 – $80 |
*When planning a deck, several factors influence the cost. Here’s a breakdown of what you need to consider:
Design Choices
The cost varies based on color and texture. Intricate composite decking resembles wood and costs more, while basic options are more budget-friendly.
Composite Decking
Capped composite decking is pricier due to an extra protective layer that enhances durability against the elements compared to uncapped decking.
Decking Types
Hollow composite decking is adequate for most needs, but if you want more durability, solid composite decking, though more expensive, might be the way to go.
Fastening Methods
Traditional fasteners are quicker and cheaper, but if aesthetics matter, hidden fasteners offer a sleeker look at a higher cost.
Support Structures
In colder areas, concrete footings must go below the frost line, and avoid burying wooden posts to prevent rot.
Drainage Solutions
Installing a drainage system under the deck ranges from $1,000 to $4,000, crucial for preventing water damage.
Elevated Deck Drainage
Costs can rise if you add a drainage system under a second-story deck.
Gravel Base
Pea gravel costs between $0.85 and $2.80 per square foot. It prevents weeds and aids water drainage.
Railings
Adding vinyl or wood railings costs $20 to $60 per foot.
Stairs
Installing stairs is $20 to $30 per square foot, plus an additional $80 to $160 for a concrete foundation.
Ground Leveling
Expect to spend $500 to $1,000 to prepare the ground before construction.
Location
Labor costs vary, generally higher in cities with more demand for deck construction.
Permits
Building permits range from $50 to $150, depending on deck size and local regulations.
Design Fees
Hiring a structural engineer costs $100 to $220 per hour for planning. For large or complex projects, their expertise may be necessary.
Understanding these elements can help you budget effectively for your deck project and ensure a smoother building process.

When it comes to decking, choosing composite materials offers durability and a range of styles:
- Composite Decking: Priced between $4 and $16 per square foot, these boards are a popular choice. Additional structures like footings, steps, and railings will add to the cost.
- Polyethylene (HDPE) Decking: Mimics the look of natural wood but retains more heat. Light colors are better for sunny areas.
- PVC Decking: Offers various colors but is more susceptible to temperature changes and mold.
- Polypropylene (PP) Decking: Handles heat better and resists buckle when wet, though it may be brittle in cold conditions.
Investing in outdoor features can transform your space into a personal oasis, offering both comfort and style.
Composite Decking Material VS. Wood Decking
Installing composite decking typically ranges from $40 to $80 per square foot, whereas a wood deck costs between $25 and $50 per square foot. Although composite decking may be more expensive initially, its advantage lies in its durability and minimal maintenance—no need for resealing, and it lasts longer than many wood options.
Maintenance and upkeep costs for composite decks
If you’re considering installing a 20×20 composite deck, it’s important to take into account the long-term cost benefits of this choice. Composite decking offers numerous advantages over traditional wood decks, including lower maintenance requirements and increased durability. This means that while the upfront cost of composite decking may be higher, the savings in maintenance and upkeep costs make it a wise investment in the long run.
When it comes to maintaining a composite deck, you’ll find that it requires significantly less effort and expense compared to wood decks. Unlike wood, which needs regular staining, sealing, and painting to keep its appearance intact, composite decking simply needs occasional cleaning with soap and water. This minimal maintenance not only saves you time but also eliminates the need for expensive maintenance products.
