How it works

How we calculate the cost

1. Area × material price

The base deck cost is the area (length × width) multiplied by the material price per square foot. Standard composite — $45/sq ft, Cedar — $35/sq ft.

2. Perimeter × railing price

Railings run along the deck perimeter. Standard pine wood — $12/lin ft, aluminum — $48/lin ft, cable rail — $55/lin ft. Glass panel is the priciest option at $85/lin ft.

3. Stairs (fixed cost)

Each stair flight is $550 for materials and labor. Estimate is calculated for 3 steps per flight. Most decks have 1 flight; large or multi-level ones have 2–3.

4. Add-ons

LED lighting — $450 (2–3 fixtures). Built-in bench — $400. Pergola — $2,200. All prices include materials + labor.

5. Permit + structural

Wisconsin requires a permit for decks over 24" in height. That adds $200–$500 depending on the municipality. Included in our final quote.

6. Range ±15%

The calculator shows a range because the real price depends on site access, foundation type, and soil conditions.
