Average Deck Building Costs in Spokane, Washington

The average cost to build a deck in Spokane ranges from $15,000 to $60,000, depending on factors like size, materials, and features. It’s a broad range, but there are good reasons for this. Deck size, choice of materials, design complexity, and added features all play a significant role in determining the final price. Below is a quick overview of what you might expect based on deck size:

  • Small Decks (under 120 sq. ft.): Cost between $10,000 and $20,000. These are typically simpler designs for cozy spaces like small patios or compact backyards.
  • Average Decks (120 – 320 sq. ft.): Cost between $19,200 and $31,500. These decks are ideal for medium-sized backyards and offer enough space for outdoor dining, lounging, or grilling.
  • Large Decks (320 – 480 sq. ft.): Cost between $32,000 and $55,000. These decks accommodate more seating, entertainment areas, and features like built-in seating or pergolas.
  • Extra-Large Decks (over 480 sq. ft.): Cost between $55,000 and $100,000+. These extensive decks offer multi-levels, custom features, and room for outdoor kitchens, hot tubs, or other luxury add-ons.

 

Knowing the cost ranges is a good starting point, but let’s dive into what really affects the pricing.

Key Factors That Impact Deck Building Costs in Spokane

Several factors can affect the total cost of building a deck in Spokane. By understanding these factors, you can make informed choices that align with your budget and design goals.

1. How Deck Size and Layout Affect Costs

The size of your deck is one of the biggest factors influencing the total cost. The larger the deck, the more materials and labor are required, naturally driving up the price. However, deck layout also matters. Simple shapes, like rectangular decks, are generally more cost-effective because they require less time and material to construct.

Curved designs, multi-level layouts, or custom shapes add to the complexity and increase the labor and material costs. For instance:

  • A 12×16 deck can range from $19,200 to $31,700, offering a comfortable space for seating and small gatherings.
  • A 16×20 deck might cost between $32,000 and $52,800, allowing for larger outdoor dining sets, a fire pit area, or additional furniture.

 

When considering your deck’s size and layout, think about how much usable space you want and what features you need. More space means more opportunity for hosting, but it also comes with higher costs.

2. Choosing Between Wood and Composite Decking Materials

The materials you choose for your deck can dramatically affect both the initial cost and long-term maintenance. Here’s how the two primary options stack up:

  • Wood Decking: Cedar is a popular choice in Spokane due to its natural look and relatively lower cost, ranging from $6 to $9 per sq. ft. While it’s less expensive than composite, it does require regular maintenance like staining and sealing to prevent rot, warping, and insect damage. Cedar provides a warm, traditional aesthetic but will need more care over the years to maintain its appearance and integrity.
  • Composite Decking: Composite materials are highly durable, require minimal maintenance, and are resistant to rot and insects. Prices range from $8 to $20 per sq. ft., depending on the brand and quality. Additionally, composite decking often comes with warranties ranging from 25 to 50 years, providing peace of mind and long-term value. While the upfront cost is higher than wood, composite decking can save you time and money on maintenance in the long run. If you’re looking for a hassle-free option, composite might be worth the extra investment.

 

Keep in mind that while composite costs more upfront, it doesn’t require the same level of upkeep as wood, making it a strong contender for homeowners who want a low-maintenance outdoor space.

3. Cost of Additional Deck Features (Pergolas, Lighting, etc.)

Adding features to your deck can elevate both its functionality and cost. Here’s a look at some popular deck features and what you can expect to pay:

  • Pergolas: A pergola adds shade and structure, making your deck more versatile. Costs range from $8,000 to $25,000, depending on the size and material (wood vs. composite). A simple pergola over part of the deck is less costly than a custom pergola covering the entire space.
  • Lighting: Deck lighting is not only aesthetically pleasing but also improves safety for evening use. Professionally installed lighting can range from $350 to $500 per light, depending on the type of fixtures you choose (e.g., in-deck, rail, or overhead lights).
  • Built-In Seating: Adding built-in benches or other seating options costs about $400 to $550 per linear foot. Built-in seating is a great way to maximize space and add a custom touch to your deck, offering both practical and aesthetic benefits.

 

These features are optional but can make your deck much more enjoyable and versatile. However, they will add to your overall budget, so be sure to prioritize based on your needs and budget.

4. Labor Costs for Building a Deck in Spokane

Labor typically accounts for about 50% of the total deck construction cost. In Spokane, labor costs range from $45 to $80 per sq. ft., depending on the complexity of the project. For instance:

  • A 16×20 deck costing $32,000 will likely have labor costs between $14,400 and $25,600.

 

Labor costs can vary based on factors like:

  • Deck height: Elevated decks require more labor and safety measures.
  • Accessibility: If your yard is difficult to access, it may take longer to transport materials and set up equipment.
  • Design complexity: Custom shapes, curves, and multi-levels require more labor time and expertise.

 

Hiring a professional deck builder like Pacific Northwest Decks ensures quality craftsmanship and reduces the risk of costly mistakes, which can be common with DIY projects.

Detailed Breakdown of Deck Building Costs

To better understand the costs involved, here’s a breakdown of some of the key components:

How Footings and Foundations Contribute to Total Deck Cost

Footings are essential for providing a stable base, especially for raised decks. Footing costs depend on soil conditions and size:

  • Concrete footings cost between $400 and $800 each.
  • For a 12×16 deck, you’ll likely need 3 footings, totaling around $2,000.

 

Concrete footings ensure the deck’s stability and safety, making them a critical component of the build.

Framing Costs: Pressure-Treated Wood

Framing is the backbone of your deck, supporting the decking and any additional features:

  • Pressure-treated wood framing costs about $6 to $8 per sq. ft., providing strength and resistance to insects and rot.
  • For a 12×16 deck, framing materials might cost around $1,800, with labor adding another $2,880.

Comparing Wood and Composite Decking Costs

Here’s a recap of decking material costs:

  • Wood Decking: Costs range from $6 to $9 per sq. ft. for cedar.
  • Composite Decking: Costs range from $8 to $20 per sq. ft., depending on quality and brand.

 

For a 12×16 deck, wood decking could cost between $1,152 and $1,728, while composite materials could range from $1,536 to $3,840.

Costs of Handrails, Fasteners, and Joist Tape

Safety features are essential for raised decks, especially those over 32 inches high:

  • Handrails: Cost $60 to $95 per linear foot for materials, with installation adding another $35 to $65 per linear foot.

 

Fasteners and Joist Tape: These are crucial for the structural integrity and longevity of your deck. Joist tape costs about $1.50 per sq. ft., helping to prevent moisture damage and extending the life of the deck.

Additional Deck Building Costs to Consider

Besides materials and labor, there are other costs to factor in when building a deck in Spokane.

Demolition and Disposal of an Old Deck

  • Demolition costs range from $8 to $12 per sq. ft., depending on the deck’s condition and materials. This includes removing and properly disposing of old materials.

Obtaining a building permit is essential for legal and safety reasons:

  • Permit fees in Spokane range from $350 to $600, depending on the deck’s size and complexity. For more details, check out our blog, Do You Need A Permit To Build A Deck?.
  • Inspections are also required to ensure the deck meets local building codes, which can add to your timeline and costs.

Ongoing Maintenance Costs for Wood and Composite Decks

Regular maintenance keeps your deck looking good and ensures its longevity:

  • Wood decks require staining and sealing every 2-3 years, costing between $5 to $15 per sq. ft. each time.
  • Composite decks need occasional cleaning but have lower maintenance costs compared to wood.
