What Are the Material Costs for Building a Deck?
Material costs are a major factor in the overall price of your deck.
Here’s a breakdown of some common materials and their characteristics.
Cost of Composite Decks
Composite decking is priced around $45 per square foot.
It is renowned for its impressive durability, often lasting between 30 to 50 years with minimal maintenance.
Composite decking is made from a mix of wood fibers and recycled plastic, which makes it resistant to rot, warping, and insect damage. This material doesn’t splinter, crack, or fade easily, ensuring that your deck looks great with just occasional cleaning.
Its low-maintenance nature means you won’t have to worry about frequent repairs or upkeep, making it an ideal choice for busy homeowners.
Cost of Ipe/Mahogany Decks
Ipe and Mahogany are premium hardwood options that cost about $55 per square foot.
These hardwoods are incredibly dense and durable. Typical lifespans range from 25 to 40 years.
Ipe, also known as Brazilian Walnut, is one of the hardest woods available. It is highly resistant to scratches, rot, and insects.
Mahogany, similarly, offers excellent durability and a rich, elegant appearance.
Both woods require regular maintenance, including sealing and staining, to protect against weather and UV damage. Proper upkeep preserves their natural beauty and ensures long-term performance. The rich color and natural grain of these woods can enhance the aesthetic appeal of any outdoor space by adding a touch of luxury and sophistication.
Cost of Cedar Decks
Cedar decking is a more budget-friendly option, costing around $37 per square foot.
Cedar is a moderately durable wood that typically lasts 15 to 20 years. Its inherent oils make it naturally resistant to rot and insect damage. Cedar decks are a good choice for humid or rainy climates.
However, annual sealing and cleaning is needed to maintain its appearance and structural integrity. The wood’s natural beauty, with its warm tones and distinct grain patterns, can create a welcoming and rustic feel for your deck. Additionally, cedar is lightweight and easy to work with, which can help reduce installation costs.
New Deck Build: Material Costs Table
| Material | Cost per Sq Ft | Durability | Maintenance |
| Composite | $45 | High (30-50 years) | Low |
| Ipe/Mahogany | $55 | High (25-40 years) | Moderate |
| Cedar | $37 | Moderate (15-20 years) | Moderate |
Labor Costs for New Deck Build
Labor costs can vary greatly depending on the complexity of your deck design, its size, and regional factors.
In Seattle, for example, labor costs typically range from $15 to $35 per square foot.
Simpler designs like a basic ground-level deck are on the lower end of the spectrum.
Complex, multi-level decks or those with intricate custom features will cost more.
Several factors influence these costs:
- Deck Size: Larger decks require more labor and materials, increasing the overall cost.
- Design Complexity: Multi-level decks, custom shapes, and additional features such as built-in seating or planters can significantly increase labor costs.
Does the Size and Design Complexity Affect Deck Build Costs?
Absolutely.
The size and complexity of your deck play a big role in determining the final cost.
Here’s a quick overview of how different aspects can affect your budget:
- Standard Ground-Level Deck: Typically the most affordable option, straightforward to build.
- Multi-Level Decks: More complex designs increase the cost due to additional labor and materials.
- Custom Shapes and Features: Unique designs or special features add to the expense due to the need for specialized skills and extra materials.
Average Costs by Deck Size
How Much Does It Cost to Build a Small Deck (200 sq ft)?
Building a small deck (around 200 square feet) can cost between $8,000 and $12,000 – including materials and labor.
The exact cost depends on the materials you choose and the complexity of the design.
For instance, a simple ground-level deck made from composite materials might be on the lower end, while a more intricate design with premium hardwoods could push the cost to the higher end.
How Much Does It Cost to Build a Medium Deck (300-400 sq ft)?
For medium-sized decks (300 to 400 square feet), you can expect to pay between $9,000 and $20,000. The significant variation in cost is influenced by the materials used and additional features like railings, stairs, or built-in seating.
Composite decking is a popular choice due to its durability and low maintenance, but it can be pricier upfront.
Hardwood options like Ipe or Mahogany add to the cost but offer a luxurious finish and long lifespan.
How Much Does It Cost to Build a Large Deck (500+ sq ft)?
Larger decks, those exceeding 500 square feet, come with higher costs. They typically fall within the following ranges:
- Composite: $22,500 – $30,000
- Ipe/Mahogany: $27,500 – $35,000
- Cedar: $18,500 – $25,000
These estimates include both materials and labor.
Larger decks require more resources and labor, which increases the overall cost.
Additionally, features such as multi-levels, custom shapes, and built-in elements like pergolas or fire pits will add to the total expense.
New Deck Build: Additional Costs and Considerations
Every project comes with additional considerations. Sometimes these are known, sometimes they are a surprise. Research like this better prepares you to set more accurate expectations.
One thing is for sure—a new deck will increase your home’s property value. Considering this partial return on your investment is important when adding anything to your property.
Deck Building Permits and Regulations
Permits and regulations are essential to any deck-building project.
In Seattle, obtaining a permit ensures your deck meets local building codes and safety standards.
Permit costs can vary but generally range from a few hundred to a couple of thousand dollars, depending on the size and complexity of the deck.
Failing to get the necessary permits can result in fines and costly modifications down the line. Always check with your local building department to understand the specific requirements and costs involved.
What Are the Maintenance and Lifespan of Deck Materials?
Maintaining your deck is critical to its longevity.
Here’s a comparison of maintenance requirements and expected lifespans for different materials:
Maintenance and Lifespan Comparison Table
| Material | Maintenance Requirements | Expected Lifespan |
| Composite | Low maintenance. Requires annual cleaning to remove dirt and prevent mold or mildew. | 30-50 years |

Cost-Saving Tips for Building a Deck
Can Building During the Off-Season Save Money?
Building your deck during the off-season is a smart way to save on labor costs.
Contractors often have more availability and are willing to offer discounts during their slower months.
In many regions, this means scheduling your project for the late fall or winter. While you might have to deal with less-than-ideal weather, the savings can be significant. Plus, your deck will be ready to enjoy by the time warmer weather rolls around.
What Are Some Simple Design Choices to Save Money?
Choosing simpler designs is another effective way to keep costs down without sacrificing quality.
Here are a few tips:
- Opt for a Ground-Level Deck: Ground-level decks are less complex and cheaper to build than raised or multi-level decks.
- Limit Custom Features: Features like built-in seating, planters, or complex railing designs can add up quickly. Stick to the basics to keep your project within budget.
- Use Standard Shapes: Rectangular or square decks are more straightforward and economical to build compared to custom shapes.
What Are the Benefits of Using Recycled or Local Materials?
Using recycled or locally sourced materials not only helps the environment but also can be a cost-effective choice.
- Cost-effective: Recycled materials are often cheaper than new ones. They provide the same functionality at a lower price.
- Environmentally friendly: Choosing recycled or sustainable materials reduces your environmental footprint. It’s a great way to make your project eco-friendly.
- Availability: Local materials reduce transportation costs and support local businesses. They are often readily available, reducing delays in your project.
