How Much Does It Cost to Build a Deck?
Not all decks are the same, and several elements can impact how much you’ll spend. Here’s what to consider:
- Size: Larger decks will naturally require a larger budget.
- Design Complexity: Multi-level decks or those with intricate designs may cost more due to increased labor and materials.
- Materials: The type of material you choose significantly impacts the cost.
- Installation Method: Installing the deck yourself will save on labor costs, while hiring professionals will increase expenses but give you a higher quality finish, more time on your hands, and less risk.
If Home Advisor says the average national cost to build a deck ranges from $30 to $60 per square foot, including labor and materials – you should know what factors go into the variance in pricing.
The higher end of that range applies to complex designs or premium materials, while simpler designs with less expensive materials can keep costs on the lower end.
Decking Materials
The material you choose for your deck plays a major role in the overall cost. On average, materials make up about 30% to 50% of the total project price.
Material options include: Fiberglass/Composite | Trex | Pressure Treated Wood | Aluminum | Redwood | Cedar | Bamboo | Cement
Remember, decking boards are only part of the equation. You’ll also need framing, supports, and other essential components to complete the structure.
Deck Styles and Costs
The style of your deck will affect the overall price:
- Platform Deck: A basic, single-level deck located close to the ground. Since it doesn’t require stairs or railings, it’s one of the most affordable options.
- Raised Deck: These decks are elevated and often attached to the second story of a house, requiring steps, railings, and additional support.
- Multi-Level Deck: Spanning two or more levels, these decks require more structural support and time to build.
Deck Size and Cost
As decks increase in size, so do the costs. Here are some of the more commonly sized decks – consider measuring it out on your back porch to identify how large you want to go because size does matter!
Deck Size Options: 10×10 (100 sq ft) | 12×12 (144 sq ft) | 14×20 (280 sq ft) | 16×20 (320 sq ft) | 20×20 (400 sq ft)
Additional Features and Their Costs
Adding extra features can make your deck more functional but will increase the total cost:
- Stairs: Necessary for multi-level decks
- Railings: Crucial for safety
- Lighting: Deck lights

- Furniture: To save, consider shopping during off-season sales.
Labor Costs
Hiring a deck contractor to install your deck will likely make up a large portion of your budget—but you will have less risk, better quality, and a project completed often times much faster than if you were to DIY.
