What’s different about Illinois
Illinois pairs harsh freeze-thaw winters with Chicago's strict permitting and unionized labor, raising costs in the metro relative to downstate.
- Insulated siding and careful house-wrap detailing add cost in cold climates.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
Expect quotes toward the higher end in Illinois’s larger metros — Chicago, Aurora, and Naperville — where labor and permit costs run above the state average, and lower in rural areas.
How the cost is built
Siding cost is driven by wall area, material (vinyl is the budget option; engineered wood and fiber cement cost more), the number of stories, and trim around windows and doors. Tearing off old siding and repairing sheathing underneath adds to the total.
Resale value
New siding is one of the highest-return exterior projects — fiber-cement siding recoups roughly 80–88% of its cost at resale, per the annual Remodeling Cost vs. Value report.
