Many homeowners planning to expand their outdoor space wonder, how much does a new deck cost? The answer depends on several key factors—including materials, size, design complexity, and installation costs. On average, in Wisconsin and Minnesota, homeowners can expect to pay between $25 and $60 per square foot for a professionally built deck. However, every project is unique, and prices can vary significantly based on customization and material selection.
- Regional pricing: Deck costs in Wisconsin and Minnesota depend on local labor rates, material availability, and climate.
- Customization: Features like railings, lighting, and built-in seating can increase total cost.
- Material choice: The biggest factor affecting your final price per square foot.
Why Deck Costs Vary
No two decks are exactly alike. A small wood deck built for a simple patio will cost far less than a large, multi-level composite deck with lighting and stairs. Climate plays a role too—contractors in Stillwater and surrounding areas often build decks with additional weatherproofing or frost-resistant footings to handle harsh winters. Understanding the cost factors helps you budget realistically and choose the best deck for your needs and lifestyle.
Average Deck Costs in Wisconsin and Minnesota
Here’s what homeowners in these states can expect to spend in 2025:
| Deck Type | Average Cost per Sq. Ft. (Installed) | Total Cost Range (200–400 Sq. Ft.) | Maintenance Level |
| Pressure-Treated Wood | $25 – $35 | $5,000 – $14,000 | High |

These prices include both materials and professional installation. Labor rates vary slightly between Wisconsin and Minnesota but generally fall within similar ranges.
6 Key Factors That Determine Deck Cost
Here are the six main factors that influence how much a new deck costs for homeowners in Stillwater and surrounding areas.
- Deck Size and Layout
The most straightforward factor affecting cost is deck size. Larger decks require more materials and labor, which increases the total price. A small 10×10-foot pressure-treated deck might cost around $3,000, while a spacious 20×20 composite deck could easily exceed $16,000. Complex layouts—such as multi-level decks or curved designs—require extra framing and time, raising costs even further. - Material Choice
Material is the biggest cost driver in deck construction. Pressure-treated wood remains the most affordable option but requires regular staining and sealing. Cedar and redwood cost more but offer a natural, beautiful finish with moderate maintenance. Composite and PVC decking have higher upfront costs but last decades longer and require minimal upkeep. For Stillwater homeowners who want long-term durability and easy maintenance, composite materials often provide the best value. - Labor and Installation Costs
Labor typically accounts for 40–60% of your total deck cost. Experienced contractors ensure decks are safe, structurally sound, and compliant with local building codes. Labor costs vary based on deck complexity—simple rectangular decks cost less than intricate, custom builds with built-in features. Choosing licensed and insured professionals like Voyager Exteriors guarantees proper construction and lasting results. - Design Complexity and Features
A basic deck provides functionality, but added design features can transform it into a luxury outdoor living space. Built-in seating, planters, multi-level sections, or integrated lighting systems increase both materials and labor costs. For example, adding composite railings may cost $60–$120 per linear foot, while installing lighting can add $1,000–$2,000 depending on the design. Homeowners in Stillwater and surrounding areas often enhance decks with pergolas or privacy screens for added comfort and style. - Permits, Site Prep, and Foundations
Every deck requires a solid foundation, which can significantly affect the budget. Concrete piers or helical piles are common in Minnesota and Wisconsin due to frost depth requirements. Site preparation—such as removing old structures or leveling uneven terrain—adds to the total cost. Building permits typically range from $150 to $500 depending on the city, but they ensure your deck meets safety and zoning regulations. - Season and Market Conditions
Timing can impact pricing, especially if you build during peak construction season. Deck builders are busiest from late spring through summer, when demand—and pricing—are highest. Scheduling your project in fall or early winter may save on labor costs. Material prices can also fluctuate based on market trends, supply chain issues, and regional availability. Staying flexible on scheduling can help manage costs effectively.
How to Estimate Your Deck Project Budget
When estimating how much a new deck costs, consider the total scope of work—not just the square footage.
Basic Deck Build (Budget Range: $5,000 – $10,000)
Perfect for small spaces or entry-level projects. Typically uses pressure-treated wood or cedar, with simple stairs and railings.
Mid-Range Deck Build (Budget Range: $10,000 – $20,000)
Includes larger decks or upgraded materials like composite decking. Often features built-in seating, improved railings, or two-tier designs.
Premium Deck Build (Budget Range: $20,000 – $35,000+)
Custom designs with high-end materials such as PVC or aluminum decking. May include lighting, pergolas, and decorative railings. Ideal for homeowners wanting a low-maintenance deck with a luxury feel.
Cost Comparison: Materials vs. Longevity
| Material | Lifespan | Maintenance | Typical 20-Year Cost |
| Pressure-Treated Wood | 10–15 years | High | $12,000 – $18,000 (including upkeep) |
| Cedar / Redwood | 15–20 years | Moderate | $14,000 – $22,000 |
| Composite Decking | 25–30 years | Low | $12,000 – $20,000 |
| PVC Decking | 30–40 years | Very Low | $13,000 – $21,000 |
| Aluminum Decking | 40–50 years | Minimal | $14,000 – $24,000 |
Although composite and PVC decking cost more initially, their low maintenance needs often make them more cost-effective long-term compared to wood decks that require regular upkeep.
FAQs About Deck Costs
1. How much does a new deck cost to maintain each year?
Maintenance costs depend on the material. Wood decks may require $200–$600 annually for cleaning, staining, and sealing, while composite and PVC decks typically cost less than $100 per year for basic cleaning.
2. Can I build a deck myself to save money?
DIY deck projects can save labor costs, but they come with risks. Improper construction can lead to structural failure, water damage, or failed inspections. For safety, warranty coverage, and long-term value, it’s best to work with licensed deck builders like Voyager Exteriors.
3. What’s the most cost-effective deck material for Minnesota’s climate?
Composite decking offers the best balance of durability, affordability, and low maintenance for cold climates. It resists warping, cracking, and fading from snow and UV exposure, making it ideal for homeowners in Stillwater and surrounding areas.
