Build Your Order: Upgrades for 10 Windows
Pick your extras with the price in view. For 10 vinyl windows, each choice works out to:
Glass, Frames and the Charleston Seasons
In a warm climate, windows let in more heat than they lose. A low-SHGC Low-E coat keeps rooms cooler and trims the cooling bill; argon matters less than the coating here.
Climate regions run from 1 (cool) to 5 (hot); South Carolina sits in region 4.
Storm season changes the shopping list. If your home sits in a wind-borne debris zone, the permit office will want impact-rated glass or code-approved shutters - neither is part of the $4,750 to $8,020 figure above, so get it priced line by line.
Muggy air finds its way into tired frames. Sealed insulating glass and a rot-proof vinyl or fiberglass frame cut the upkeep that wood sash demands in damp weather.
Heat and glare are the main complaints about old windows in Charleston. A low-SHGC coating handles both. If you want dark exterior frames, fiberglass ($8,160 to $13,790) copes with the heat better than vinyl.
Plan to finish before hurricane season. Impact-rated units can take longer to build, and installer calendars fill fast once storms are in the forecast. Compared with the northernmost cities in this South Carolina guide, Charleston lies about 2.2° farther south; more sun on the glass makes a heat-blocking Low-E coat the upgrade to keep. Window prices for Charleston (Charleston County) are worked out apart from those of Mount Pleasant, the nearest listed city, about 8 miles east.
How to Compare Window Bids in Charleston
Before you pick a bid in Charleston, make every installer cover the same three points:
- Insert or full-frame. An insert keeps the old frame and costs less; full-frame removal fixes rot and air leaks but adds labor and trim work.
- Glass package. Get the Low-E type, argon or krypton fill and U-factor in writing for every window.
- Trim and finish. New interior stops and exterior metal capping are often extra - here they add about $1,950 for 10 windows.

Window Replacement Questions
Do premium frames pay off?
Fiberglass costs $8,160 to $13,790 for the job above against $4,750 to $8,020 for vinyl. It is stiffer, expands less and takes paint, so it suits dark colors and large openings; for most standard windows, vinyl gives more value per dollar.
Will I be without windows for long?
Expect a site measure first, then a factory wait for the made-to-size units. The install itself is short: 10 windows are usually in within one or two working days.
What does a Charleston installer charge per opening?
Per opening, plan on $474.33-$801.84 for a vinyl double-hung. A slider comes to about $890.41; ordering one or two units alone usually costs more each.
