Ah, nothing beats relaxing outside with friends or family on a brand new deck. For homeowners in the St. Louis area, adding a deck can be a smart way to boost your home’s value, create more outdoor living space, and add a touch of style to your backyard. But before we start picturing fire pits and pergolas, most of us share the same key question: how much does building a deck cost?

The answer isn’t as straightforward as we’d like. The total cost depends on several factors, including your choice of decking materials, the size and layout of your deck, and the labor needed for a safe installation. Let’s break it all down so you know what to expect and where your investment makes the most sense.

Building a deck isn’t a one-size-fits-all project. Costs can swing widely depending on what you want and what your property needs. To get the most accurate idea of your deck cost estimates, it helps to look at the main variables that shape the price tag of every deck project.

Think of square footage first: the larger the deck, the more you’ll need to invest in materials and labor. A small, 200-square-foot ground-level deck will cost much less than an elaborate multi-level deck design that wraps around your home. Want something custom, like curved edges, built-ins, or floating decks? These creative shapes and levels can take more time and materials, and increase the overall cost.

The type of material you choose plays a huge role in your new deck’s look, lifespan, and new deck cost. While wood decks remain a classic choice, composite materials like Trex decking are gaining ground due to durability and lower maintenance. Upgrades, such as adding a hot tub, custom railings, pergola, or high-end finishes, can make your deck pop, but will bump up the upfront decking price.

For those considering high-performance options, our Composite Decking Options offer insight into long-lasting and visually appealing choices.

Labor costs are a key part of the budget. Hiring experienced pros means your deck installation is built to last and complies with local building codes. While DIY deck projects might save on initial labor expenses, mistakes can lead to pricey repairs or a deck that doesn’t stand the test of time. Homeowners should also remember that labor costs can fluctuate based on deck complexity and contractor demand.

On average, a deck in 2025 costs between $10,000 and $35,000. Most homeowners pay around $25,000. Prices depend on size, materials, and labor. A basic 12×12-foot deck might run $10,000 to $15,000. High-end decks with custom features or premium materials can cost $20,000 or more.

Key factors include deck size, type of materials, design complexity, local labor rates, and add-ons like stairs or benches. Removing an existing deck or making site improvements will also raise your total.

Pressure-treated wood costs about $5 to $10 plus installation. Composite decking ranges from $8 to $24 per square foot for materials, but installation brings the total to $60 to $100 per square foot. Premium hardwoods like Ipe or mahogany can run $15 to $75 per square foot plus installation.

Plan for $50 to $80 per square foot for labor, depending on where you live and your project’s difficulty. Labor often accounts for half or more of the total bill.

Yes. Simple, ground-level decks are usually on the lower end of the price range. Multi-level, floating, or curved decks add labor hours, engineering, and special materials, making them much pricier.

DIY can cut costs by 30% to 50% because you save on labor. However, you’ll still need to buy materials, get permits, and possibly rent or buy some tools. Mistakes can be expensive, so only take this route if you’re handy and ready to follow local building codes.

Stairs can be one of the most expensive parts of the deck. They are also the most critical to be built properly for safety.

Yes. Urban areas or regions with a high cost of living usually have higher labor rates. Some locations may also require stricter permits, adding to your expenses.

Depending on your city, permits can cost $100 to $500 or more. Inspections may be extra. Always check your local regulations to avoid fines or delays.

A well-built deck can increase your home’s value. Many homeowners recoup up to 89% of the cost when they sell their house.

Pressure-treated wood needs annual sealing or staining, costing $500 to $1,000 a year. Composite and premium woods cost more upfront but need less upkeep, saving you time and money over the years.

You have options: home equity loans, lines of credit, personal loans, or credit cards. Home equity lines usually offer lower rates if you qualify. Consider what works best for your budget and timeline. Outdoor Living does not offer financing, but we are happy to talk about payment plans and working with your budget.

Yes! For many homeowners, composite decking pays off in the long run. Though the upfront cost is higher than pressure-treated wood, composite decks require far less maintenance, last longer, and resist issues like warping, splintering, and fading.

Yes, in most areas—including the St. Louis metro—permits are required for new deck construction or major renovations. Outdoor Living Inc. handles the permit process for you when we build your deck, ensuring all code requirements are met.

Composite decking is made from a mix of recycled wood fibers and plastic, offering a wood-like appearance with less maintenance. PVC decking, on the other hand, is made entirely from synthetic material, making it more moisture-resistant, lighter, and even lower maintenance, which is ideal for wet or high-heat environments.

No two homes, families, or backyards are exactly alike. That’s why getting a professional estimate is smart.
