Average Cost to Build a Deck
Building a deck is a significant investment that enhances your outdoor living space and adds value to your home. The cost to build a deck varies widely based on factors like size, materials, design complexity, and labor. Nationally, the average cost ranges from $4,000 to $45,000, with an average of around $7,500. In Seattle, local labor rates and weather conditions can affect costs and material choices. This guide covers the average costs, factors influencing these costs, material options, and labor considerations to help you plan and budget for your deck project effectively.
Factors Influencing Cost
Factors influencing the deck cost include size, material, and design complexity. Larger decks generally cost more but have a lower cost per square foot due to economies of scale. The type of material used significantly impacts the total cost. Pressure treated lumber is the least expensive, while exotic hardwood and composite decking materials can be much more costly. Simple, rectangular designs are more affordable, whereas complex designs with multiple levels, built-in seating, or custom shapes increase the cost due to additional labor and materials required. Make sure to leverage your local professionals for exact estimates, but a deck cost calculator will do for anything you need to handle on your own.
Material Suggestions

Cost-Saving Tips
When planning to build a deck, several strategies can help manage and reduce deck building costs. Firstly, choosing simple designs can significantly lower the project cost. Complex structures like multi level decks, rooftop decks, or those with custom features such as deck stairs or a floating deck increase both material and labor costs. Opting for cost-effective materials, such as pressure-treated lumber instead of exotic hardwoods, can also save money.
Building during the off-season is another effective way to cut costs. Local deck contractors are typically less busy during the colder months, which can result in lower labor expenses. Additionally, planning your deck with future maintenance costs in mind is crucial. For example, composite decks and recycled wood materials may have higher initial costs but require less maintenance than natural wood decking, resulting in long-term cost savings.
