Do I need a permit for window replacement in Charleston, South Carolina?

Get at least three written quotes from licensed, insured South Carolina contractors. Comparing line items — not just the bottom line — is the fastest way to spot an inflated bid in the Charleston metro market.

How much does one replacement window cost?

$450 to $1,500 installed for a standard double-hung window; premium fiberglass, wood-clad and oversized units run $1,500 to $2,600.

Is it cheaper to replace all windows at once?

Yes. Crews spread mobilization and setup across the job, and most manufacturers discount orders of 8 or more units, which usually saves 10% to 20%.

Insert vs full-frame replacement?

Inserts reuse the existing frame and cost 20% to 35% less. Full-frame replacement is required when the sill, jamb or surrounding wood is rotted.

Do new windows pay for themselves?

Energy savings typically run $125 to $465 a year replacing single-pane windows, and window replacement returns roughly 60% to 70% of cost at resale.

What upgrades actually matter?

Double-pane low-E with argon fill is the value sweet spot. Triple pane pays off mostly in very cold climates or on noisy streets.

How long does installation take?

About 30 to 60 minutes per window, so most whole-home jobs finish in one to three days after a two- to six-week manufacturing lead time.
