We take the middle of the guides' lows for the low end, the middle of their highs for the high end, and the middle of their averages for the typical deck building price. Where a guide gives no average we use its midpoint. All read on October 9, 2026.
Labor share used: 50%. None of the guides splits labor out for this job, so this share is Koira's working assumption for patios, decks and outdoor living work. State factor: the state's median hourly wage for construction and extraction workers over the national $28.63 (BLS, May 2025), kept between 0.7 and 1.4.
