Within each, you choose the style, double-hung and casement being the most common, and the glass package that suits your climate. Many homeowners bundle window replacement and door replacement, since both are handled by the same crews.

Installed cost in Charleston runs roughly 4% below the national average for this trade. Here's how we got to that number.
Project costs include three main components: labor, materials, and overhead. Material ships at national prices no matter where you live, and overhead is fairly consistent as well. So the main pricing difference between metro areas is labor costs. This is why a quote from a high-wage metro is rarely as far above the national average as people expect.
To get Charleston labor costs, we compared the average hourly wage in the Charleston-North Charleston, SC area to the national average hourly wage for this trade. (source: US Bureau of Labor Statistics, Occupational Employment and Wage Statistics, May 2025)
We found that the local trade wages sit about 17% below the national figure. Labor costs typically make up about 26% of a window replacement project cost, so the weighted difference between Charleston and national averages is −4%. See methodology and sources.
