How these prices are built
Every price on this page comes from JobFlex's contractor price book: what a homeowner pays a licensed contractor for each step of the job, as a U.S. national average per unit, with the contractor's overhead and profit included and sales tax left out. The house painting is priced step by step, then multiplied by Naperville's construction cost index of 1.22.
Where the price book's steps for an option add up to more than 20% over the installed price a published source gives for the whole job, every step but a permit fee is scaled down to the middle of that range: exterior: siding & body × 0.52 (HomeGuide 2026: $1.00–$3.00 per sq ft painted).
The index weighs local construction wages (BLS Occupational Employment and Wage Statistics, May 2025) at 60% and the area's material prices (Craftsman ZIP-area factors) at 40%. Published indices for Naperville, each on its own base: Craftsman 1.17. Treat any city figure as about ±5%; a contractor's quote for your house is the number to plan with.
