Charleston Window Pros provides professional commercial storefront glass in Charleston, SC for residential and commercial properties across the South Carolina Lowcountry. Commercial glazing is a different license, a different board and a different order of operations from residential work, and treating it as a bigger version of a house is how downtown storefront projects end up months late and thousands over.
The license first. In South Carolina, Glass and Glazing is a general contractor classification under Section 40-11-410, and it is the classification that names curtain wall systems, mall fronts and architectural window systems. A contractor's license is required once total construction cost passes ten thousand dollars, and bid limits run by license group under Section 40-11-260. Ask any bidder which group they hold before you compare numbers.
The review is the second layer, and downtown it is the one that governs the calendar. Commercial-scale work in the Old and Historic, Old City and Historic Corridor districts is generally heard by the Board of Architectural Review-Large rather than settled by staff, and BAR-Large meets monthly with a capped agenda. Missing a meeting costs a month, not a week, and a deferral costs two.
That is why we sequence a King Street or East Bay storefront the same way every time. Survey and template, then the review submission with elevations and finish samples, then approval, then fabrication, then a single install window. Ordering aluminum before the board has seen it is how a project ends up storing a rejected system in a warehouse.
On the technical side, most Charleston storefronts are center-set or offset aluminum framing at 1-3/4 or 2 inches, and the common faults are gasket failure, water in the sill flashing and racking at the corners after a door has been slammed for fifteen years. Re-gasketing and re-setting a sound frame beats replacing it in both cost and disruption, and it can usually be done overnight.
Glass in a commercial entrance is nearly all tempered or laminated by requirement rather than choice, which means every lite is cut to final size at the factory. Template accuracy is the entire job. We template from the actual opening after any framing work, never from a drawing, and we carry the sizes to the sixteenth. A quarter-inch error on a tempered lite is a reorder, not an adjustment.
Finishes deserve thought this close to the harbor. Salt-laden air attacks anodizing and paint at the fixings first, so we specify Class I anodizing or an AAMA 2605 fluoropolymer coating and stainless fasteners throughout on exposed frontages, and we say plainly when a cheaper finish is fine on a sheltered inner elevation.
We also run same-day board-up and re-glaze for storm damage and break-ins, with the opening measured at the same visit so the replacement lite is on order before the plywood goes up. For restaurants and shops that difference is trading days, and trading days are the only number that matters on that call. We give an honest glass lead time rather than an optimistic one.
Our licensed and insured team brings the right materials and equipment to every job — true divided lites bedded in glazing putty, simulated divided lite bars with a shadow spacer between panes, authentic divided lite fused-pane sash, aluminum-clad and fiberglass-clad wood frames, operable louvered Bahama and panel shutters, 7/16-inch wood structural panel opening protection — and backs the work with a written workmanship warranty. We serve Charleston and nearby communities including Mount Pleasant, North Charleston, Summerville, Goose Creek.

Materials, equipment and how we do commercial storefront glass
The difference between commercial storefront glass that lasts and commercial storefront glass that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with true divided lites bedded in glazing putty, simulated divided lite bars with a shadow spacer between panes, authentic divided lite fused-pane sash, aluminum-clad and fiberglass-clad wood frames, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Charleston job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the South Carolina Lowcountry means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Charleston Chooses Charleston Window Pros
- ✓We quote elevation by elevation, because the Board's purview is visibility from a public right-of-way and the back of a Charleston house is frequently a different product from the front
- ✓Your address gets placed in the district and building-age matrix the BAR adopted in December 2025 before any brand name is spoken, so you learn what is approvable before you learn what it costs
- ✓We will tell you when the wind code is satisfied by protecting the opening instead of replacing the glass, which on an original sash is usually both cheaper and far easier to get approved
- ✓No vinyl quoted where the policy forbids it, and no relabelling a vinyl-cored product as composite to try to slip it past staff

If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
