Concrete Patio in Washington is 4% below the national average of $4,017. This is primarily due to higher labor costs and stronger demand in Washington.
Washington experiences a mild marine climate west of the Cascades with wet, cool winters and dry summers, shifting to a cold semi-arid continental climate east of the mountains in the Columbia Basin and Palouse. Persistent rain from October through May compresses exterior windows west of the crest, while Spokane and eastern Washington face real snow and freeze loads. For concrete patio projects specifically, this means timing and material selection are key factors in both cost and quality.
Higher costs in this state are primarily driven by strong labor demand and above-average wages in the construction sector.
