Window Replacement in South Carolina

Two separate things decide a window job in South Carolina: who is licensed to do the work, which the state decides, and what the window has to do, which the climate decides.

(888) 504-4842

Licensed South Carolina installers. No obligation for the call.

The license is the checkable half. South Carolina issues it, and the trading name is frequently not the licensed entity. Ask which name it is held under — one sentence on the phone.

The federal window tax credit ended on 31 December 2025. Work installed in 2025 is still claimable on that year’s return, but there is no federal credit for 2026 installations. What remains is state and utility programmes, and they vary.

What the window itself has to do depends on where in the state you are: the ENERGY STAR criteria differ by climate zone, and several states contain more than one.

The day itself

One opening takes a couple of hours. A house takes days rather than weeks, and the order rarely changes.

Describing the job costs nothing

Nothing is measured or ordered until you say so. Useful on a first call: how many windows, what type they are, and what is wrong with them.

License
Held by the contractor and issued in South Carolina. Ask which name it is held under — a trading name and the licensed entity are often not the same.
Lead certification
Required by federal rule for paid work on any home built before 1978. It has a number, and the firm should give it without hesitating.
The call
Describing the job commits you to nothing. Nothing is measured or ordered until you say so.
