What drives deck pricing in Wisconsin

The three structural factors that make Wisconsin cheaper than the national average for renovation projects in 2026.

Milwaukee and Madison labor

Both metros run $45–$65/hr. Green Bay, Eau Claire, and rural WI drop to $38–$55/hr.

Cold-climate code requirements

WI code requires R-49 ceiling insulation and high-efficiency HVAC. Adds $1,000–$3,000 to major remodels.

Strong contractor density

Wisconsin has a deep skilled-trade pool. Competitive bidding keeps margins tight; bid spread is among the narrowest in the U.S.
