Window Replacement Cost in Idaho (2026)

Window replacements in Idaho typically run $5,200–$13,400 for a 10-window 1,500 sq ft single-story full-house window replacement, with vinyl-frame double-hung the dominant residential choice and ENERGY STAR Northern climate-zone glazing requirements (U-factor ≤ 0.3, no SHGC limit). Idaho's combination of high-altitude UV exposure across the Treasure Valley and Sun Valley driving Sun-Belt-rated UV-stabilized vinyl frames on every south-and-west-facing residential window installation, ENERGY STAR Northern climate zone driving low-U-factor (≤0.30) glazing requirement statewide, F2 freeze-thaw cycling driving sealant degradation on every window perimeter caulk at 4-6 year intervals, and northern Idaho mountain elevations above 4,000 feet drives moderate cold-climate-driven glazing selection.

Idaho climate, wind & energy-code drivers

  • ENERGY STAR climate zone: Northern — coldest climates, U-factor priority (U ≤ 0.27 in coldest tier)
  • IECC climate zone: 5B-6B
  • Maximum U-factor: 0.3 (IECC 2021 + state amendments)
  • Maximum SHGC: No limit (cold climate)
  • ASCE 7-22 design wind speed: 100 mph (Risk Category II)
  • Hurricane impact-rated requirement: No statewide impact-rated requirement
  • Dominant residential frame material: Vinyl frame — dominant in most climates, lowest cost-per-window
  • Historic-preservation overlay prevalence: Low — limited historic-preservation review outside specific neighborhoods
  • EPA RRP lead-safe trigger (pre-1978 housing share): Moderate — 20-40% pre-1978 housing share, EPA RRP required on selected replacements

Idaho licensing, lead-safe & permits

  • License status: Statewide registration required (no exam)
  • License board: Idaho Bureau of Occupational Licenses — Public Works Contractor License (PWCL) for residential >$2,000 + Idaho Contractors Registration (official site)
  • Permit: city or county building permit required for window opening modification; PWCL required for residential work above $2,000; replacement-only same-size installs typically permit-exempt; Treasure Valley HOA architectural-committee approval common on Boise-Meridian-Nampa subdivisions

How window replacement costs vary in Idaho

State-specific code or insurance rule: Idaho is one of only a few Mountain West states without a centralized residential builder license — Idaho Bureau of Occupational Licenses operates a Public Works Contractor License (PWCL) for residential window work above $2,000 plus a Contractors Registration system without examination requirement, leaving Treasure Valley homeowners to rely on PWCL bond (only $25,000) and Idaho Contractor Registration history rather than a state-board credential check, with Boise, Meridian, and Nampa HOA architectural committees separately enforcing pre-approval review on window frame color and grille pattern.
