2026 Pricing Guide
Realistic investment ranges for composite deck systems, covered structures, and custom outdoor living projects in the Fox Valley and beyond.
How Much Does a Custom Deck Cost?
Deck pricing depends on size, elevation, materials, structural requirements, and site conditions. In Northeast Wisconsin, most professionally built composite deck systems begin between $25,000 and $35,000, with larger multi-level or covered structures ranging significantly higher.
This guide outlines realistic investment ranges so you can plan confidently and determine whether Tech Five is the right fit for your project. Every range below reflects completed project investments in the Appleton, Green Bay, and Fox Valley area — not national averages.

What Impacts the Cost of a Deck?
Final pricing is driven by scope, not square footage alone. These are the primary factors that shape your investment.
Size & Layout Complexity
Larger footprints and multi-directional layouts increase material quantities and installation time. A simple rectangle costs less than an L-shaped or wraparound design.
Elevation & Structure
Elevated decks require additional framing, bracing, and frost-depth footings designed for Wisconsin snow loads and code requirements.
Material Selection
Composite tier (Trex Enhance vs. AZEK Vintage), railing type, fascia detailing, trim work, and fastening systems all influence total investment.
Stair Systems
Custom stair layouts with landings, turns, and railing transitions add structural framing and labor complexity beyond a basic set of steps.
Lighting & Electrical
Integrated stair lighting, post-cap lights, and under-deck illumination require pre-planning, wiring, and careful installation during the build.
Covered Structures & Roofs
Adding a roof structure substantially increases structural engineering, material quantities, and roofing integration complexity.
Is Price Per Square Foot Accurate?
Square footage can provide a general reference point, but it rarely defines final investment on its own. In Northeast Wisconsin, professionally built composite deck systems typically fall between $110 and $150+ per square foot, depending on elevation, layout complexity, and finish selections.
Structural requirements and design features have a greater impact on pricing than square footage alone. A 300 sq ft elevated deck with custom stairs and lighting will cost more than a 400 sq ft ground-level platform — even though it's smaller.
That's why we define scope first. Accurate pricing requires measured layouts, load planning, and clearly defined material selections — not assumptions based on rough dimensions.
| Project Type | Typical Range | Per Sq Ft |
|---|---|---|
| Standard Composite Deck | $25K – $35K | $110 – $130 |
| Mid-Range / Multi-Level | $35K – $65K | $120 – $145 |
| High-End / Covered Structure | $65K – $120K+ | $140 – $150+ |
Why Deck Pricing in Northeast Wisconsin Is Different
Building in Northeast Wisconsin requires consideration of regional climate and code requirements that influence material choices, structural design, and installation methods.
National pricing guides and online calculators rarely account for these factors, which is why local expertise matters. Proper planning ensures long-term durability and predictable performance through Wisconsin winters.
Frost-Depth Footings
Footings must extend below the frost line (48” in most of NE Wisconsin) to prevent heaving and structural movement.
Snow Load Engineering
Covered structures and railings must be designed for Wisconsin snow loads, requiring heavier framing and engineered connections.
Freeze/Thaw Cycles
Material selection and fastening systems must account for repeated expansion and contraction through harsh seasonal changes.
Building Code Compliance
Local municipalities enforce specific structural, railing, and footing requirements. Permits and inspections are part of every professional build.
Investment vs. Estimate — What's the Difference?
Here is exactly how our pricing works. At your on-site design consultation, we walk your property and discuss your goals. For most projects, we provide ballpark pricing before we leave. Within 24 hours, you receive a complete fixed-price proposal produced by our proprietary quoting software — an exact bill of materials itemized board by board, plus a build schedule showing how long each construction phase takes. No other contractor in NE Wisconsin delivers a proposal this detailed, this fast.

Are We the Right Fit for Your Project?
We are typically a strong fit for homeowners planning a project in the $25,000+ range who value quality construction, defined scope, and predictable execution.
A Good Fit If You:
- Value structural integrity and long-term performance
- Prefer defined scope before pricing
- Want predictable execution with no surprises
- Understand that quality construction requires appropriate investment
We May Not Be the Right Fit If:
- —You are seeking the lowest initial bid
- —You plan to supply your own materials
- —You are comparing budget-only contractors
- —You need a project under $20,000
Our goal is to define scope clearly before pricing so expectations remain aligned from the beginning.
Deck Cost FAQ
How much does a 12×16 composite deck cost in Wisconsin?
Most professionally built projects of that size begin around $25,000, depending on elevation, structural requirements, and material selections. Ground-level builds with standard railing will fall at the lower end, while elevated structures with lighting and custom stairs will be higher.
Is composite more expensive than treated wood?
Composite materials typically carry a higher initial cost but require significantly less maintenance over time. When you factor in staining, sealing, and board replacement over 10–15 years, composite often proves more cost-effective.
Does adding a roof double the price?
Not necessarily, but covered structures substantially increase framing, material, and labor requirements. The added cost depends on roof style, span, attachment method, and whether it integrates with the existing home structure.
Are permits included in your pricing?
Yes. We handle permitting and inspections as part of our defined project scope on every build in Northeast Wisconsin.
Do you provide itemized proposals?
We provide clearly defined scope documents outlining materials, specifications, and structural details so clients understand exactly what is included before construction begins.
How long does a deck project take to build?
Most standard composite decks take 1–3 weeks of on-site construction. Multi-level or covered structures may take 2–4 weeks. Every proposal includes a build schedule — broken down phase by phase — so you know exactly how long your project takes before construction begins. Timeline is not estimated. It is defined.
