Window Replacement Cost in South Carolina (2026)

Window replacements in South Carolina typically run $5,200–$16,400 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 Southern climate-zone glazing requirements (U-factor ≤ 0.4, SHGC ≤ 0.25). South Carolina's combination of 150 mph ASCE 7-22 design wind speed across the Lowcountry coastal counties driving SC Charleston-Lowcountry Building Code ASTM E1996 large-missile impact-rated window mandate on every coastal residential install, persistent Atlantic salt-spray on every coastal exposure, very-high TPCT termite zone 1 pressure across the entire state, ASCE 7-22 SDC C seismic design category across the entire state due to 1886 Charleston earthquake legacy, and Charleston BAR review on every Charleston historic-district window replacement (the first U.S. local historic-preservation program, established 1931) drives unique Charleston-historic-and-coastal-and-seismic-driven glazing selection.

How window replacement costs vary in South Carolina

State-specific code or insurance rule: South Carolina Residential Builders Commission §40-59 imposes one of the most credential-segmented residential builder licensing schemes in the country — every SC window contractor performing work above $5,000 must hold a Residential Builder license, plus Charleston Board of Architectural Review (BAR) separately requires review on every window replacement within Charleston's 6 designated historic districts (Old & Historic Charleston, Old City Historic District, Wragg Square, Cannonborough-Elliotborough, Hampton Park Terrace, Radcliffeborough) — one of the oldest local historic-preservation review programs in the country (established 1931, the first in the U.S.) requiring profile, glazing, and shutter-pattern continuity with the surrounding 1670-1900 architectural overlay.
