How Much Does it Cost to Build a Deck?

Deck Material Costs

The costs to build a deck can vary based on the type of material you use, as well as the square footage of the deck with those materials. For instance, pressure-treated pine is the least expensive option among your choices for natural wood decking, with a cost of approximately $3 to $6 per square foot. More exotic hardwoods – such as Ipe can range between $10 to $15 per square foot. Composite decking, such as Trex, can cost between $5 to $13 per square foot, however, it requires less upkeep than most types of natural wood.

Decking MaterialLow-End Cost (per square foot)High-End Cost (per square foot)
Pressure-treated wood$3$6
Composite decking$5$13
Ipe$10$15
Redwood$7$12
Cedar$4$8
Bamboo$3$10
Aluminum$15$20
  • Pressure-treated wood ($3 - $6 per sq. ft.)
    • Pros: Affordable and widely available. Resistant to insect damage and rot.
    • Cons: Requires regular maintenance, including sealing and staining, to prevent warping and cracking.
  • Composite decking ($5 - $13 per sq. ft.)
    • Pros: Low-maintenance and highly durable. Resistant to fading, staining, and mold.
    • Cons: Higher upfront cost compared to some wood options. May feel artificial to some.
  • Exotic hardwoods like Ipe ($10 - $15 per sq. ft.)
    • Pros: Superior durability and a longer lifespan than pressure-treated wood.
    • Cons: Very high cost and challenging to work with due to its density.
  • Redwood ($7 - $12 per sq. ft.)
    • Pros: Naturally resistant to insects and decay. Lightweight and easy to work with.
    • Cons: Can be pricey and may require periodic maintenance to maintain color.
  • Cedar ($4 - $8 per sq. ft.)
    • Pros: Naturally resistant to rot and insects. Lightweight and easy to install.
    • Cons: Not as durable as some harder woods and may require regular maintenance.
  • Bamboo ($3 - $10 per sq. ft.)
    • Pros: Eco-friendly and renewable resources. Attractive appearance and is easy to install.
    • Cons: Susceptible to moisture and may not be as durable as traditional hardwoods.
  • Aluminum ($15 - $20 per sq. ft.)
    • Pros: Extremely durable, resistant to weather, pests, and fire. Minimal maintenance is required.
    • Cons: Very high cost and may not offer the same aesthetic appeal as natural wood

Labor Cost to Build a Deck

Labor costs significantly impact the overall cost of building a deck, often accounting for a substantial portion of the budget beyond the materials. Depending on location, contractor experience, and the project's complexity, labor costs to build a deck per sq ft can range from $8 to $22. Several factors influence this variation:

  • Deck Design Complexity: Intricate designs with multiple levels, stairs, or custom features require more time and skill, leading to increased labor costs.
  • Contractor Expertise: More experienced contractors might charge higher rates, but their proficiency can ensure a more reliable and aesthetically pleasing outcome.
  • Seasonal Demand: Labor costs to build a deck can fluctuate with seasonal demand, with higher rates often seen during the peak building seasons in spring and summer.
  • Permit and Inspection Fees: Some areas require permits and inspections, which can add to the labor cost as contractors handle the paperwork and compliance aspects.
  • Access to the Building Site: Sites that are difficult to access or have limited space can require more time and effort, thus increasing labor costs

Cost to Build a Deck by Size

Costs for materials for a deck range according to a number of factors, including:

  • Square footage of your deck plan
  • Height, width, and depth of your planned structure
  • How elaborate your design is (for example, is there enough room in the budget for a shed roof?)
  • The type of materials you plan to use and how much they cost within your particular region of the country

Whether you’re wondering how much does a 14x20 deck costs, or if you want a smaller deck, such as a 10x10 deck, below are the average costs of materials to build a deck, depending on the square footage and type of material you plan to use. Please keep in mind that this does not include labor cost to build a deck and only takes into consideration the cost of materials, without railing.
