Factors in Calculating the Cost to Build a Deck
The size and complexity of the deck being constructed have a significant impact on the cost to construct it. Depending on the complexity and design of the deck, the cost to build a deck under 200 square feet can range from $3,000 to $14,000. Costs are increased by 30 to 60% when constructing a deck on the second story. The cost of building a deck can also vary depending on the materials used, design preferences, and foundation requirements.
Material
Material costs to build a deck range from $6 to $8 per square foot on average. Hardwood, pressure-treated wood, and recycled composite are the three most widely used materials in the US for building outdoor decks.
Pressure Treated Deck Cost
On average, a pressure treated wood deck costs $6 per square foot for materials, or between $12 and $18 per square foot installed. Almost 75% of decks in the US are made of pressure-treated wood (PT). It is manufactured to increase the wood’s resistance to rot, insects, and mold by applying a chemical under pressure.
Wood Deck Costs
- The materials cost to build a deck with natural wood is between $3 and $15 per square footwith most homeowners spending $6 to $8 per square foot on average. Wood decks are attractive and a popular choice among homeowners, but they need more upkeep, such as routine staining and sealing.
Redwood Deck Cost
Redwood from California is the most typical natural wood species used in deck construction. A redwood deck costs between $15 and $21 per square foot installed, and around $7 per square foot for just the materials. Compared to pressure-treated wood, redwood costs a little bit more per square foot.

Foundation
There must be substantial support structures with poured concrete footings for decks that are expected to support additional weight, such as a hot tub. Small decks that are attached to the house may only need concrete blocks for security, whereas raised decks need additional beams and footings. A poured concrete footer typically costs $200 to $400, while the average cost of a concrete decking block is $50 to $75.
Labor and Permits
For the construction of an average-sized deck, reputable decking companies typically charge between $15 and $35 per square foot. Location, deck size, and materials all affect the price. The typical cost is $500 if a building permit is necessary to add a traditional deck as a permanent structure.
Additional Costs and Considerations
You may want to include some extra features like a roof, deck skirting, a built-in kitchen, accessories, and more after discussing your unique deck requirements with a Lowe’s deck designer or another decking expert. It might be necessary to remove an outdated deck first, which will add to the cost.
Demolishing An Existing Deck
Before constructing the new deck, the old one must be torn down if it is damaged beyond repair or simply doesn’t fit your style. Depending on the needs of the new deck, the footings may be able to be reused and expanded upon or they may need to be torn out and rebuilt. A professional’s assistance in removing an old deck and foundation typically costs $500 to $2,000 in total.
Seasonality
You can have a deck built in the winter in some climates. As it’s considered off-season, decking companies may have more time to finish the job, making this a popular choice for many homeowners. Building permits might be acquired more quickly too because less construction takes place during the winter.
Features and Add-Ons
Your deck might cost an additional $3,000 to $10,000 to add a roof. Lighting installation costs can range from $8 to $150 per fixture. It can cost between $8,000 and $25,000 to enclose the deck. Patio furniture typically ranges in price from $350 to $4,000, depending on its quality.
Luxury Accessories
Consider installing heaters or misters ($100 to $300) to make the deck more comfortable all year long. In-home grills, kitchens, surround-sound televisions, or even gazebos can all increase the value of entertainment for homeowners.
Deck Skirting
Installing deck skirting is an attractive solution for raised decks to fill the empty space below the deck. Lattice, metal, sheets of wood, or vinyl are just a few examples of the materials used for deck skirting. With a typical cost of $3 per square foot, lattice is the least expensive, while stone veneer can cost up to $200 per square foot and vinyl can cost up to $50.
Electrical Work
Having power outlets on a deck is useful, especially if it is a standalone deck that is not attached to the house. electricians who can safely run power to numerous points on your deck are frequently available to deck professionals. Be sure to let the electrician know about the power requirements if you intend to install a hot tub.

Decking Railings and Stairs
Basic railings are occasionally included in the average price per square foot, but elevated decks, decks on second stories, and additional stairs are usually more expensive. More materials are needed and installation time for railings and stairs is longer than for deck planking.
Decking Pattern
Straight-lined, standard square or rectangular decks are popular options that won’t cost more. Homeowners can anticipate an additional 15% cost increase for increased labor and materials if a herringbone pattern, diagonal stripes, or any other special pattern is preferred.
Care and Maintenance
Aside from routine cleaning, composite decks don’t require much maintenance. Decks made of natural wood should be resanded, stained, or weather-sealed at least once per year ($500 to $1,200). A professional can assist in conducting routine foundation inspections and should be consulted if any boards or railings are significantly damaged.
