What’s different about Idaho
Idaho's cold winters and mountain snow load require freeze-resistant detailing, and rapid growth around Boise has tightened contractor availability.
- Insulated siding and careful house-wrap detailing add cost in cold climates.
Expect quotes toward the higher end in Idaho’s larger metros — Boise, Nampa, and Meridian — 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.
