Charleston Window Pros provides professional vinyl windows in Charleston, SC for residential and commercial properties across the South Carolina Lowcountry. This is the page where we talk you out of the product, across half of this city. The BAR's adopted window policy contains four words with no wriggle room: no vinyl or vinyl components. That applies in every district it governs, on every elevation visible from a public right-of-way.
It goes further than the frame. Composite windows are defined in that policy as products containing multiple materials, typically including vinyl or some form of plastic, and the policy's own FAQ takes the trouble to explain why they are not accepted south of Line Street. Naming two specific product lines as examples was not an accident. A product marketed as fiberglass with a vinyl core is still caught by that definition.
The stated reasoning is about profile rather than snobbery. Jamb liner color, muntin width, sash and trim dimensions all read differently from wood at ten feet, and the Board's position is that the difference is visible from the street. Whether you agree or not, it is the standing policy and it is what staff apply.
So if your address is in the Old and Historic District, the Old City District, a Historic Corridor or the Landmark Overlay, this page is not for you. Go and read the fiberglass, clad-wood or aluminum pages instead, and be careful of any quote that calls a vinyl-cored product something else to get it past a plans examiner. Staff read cut sheets, and a rejected submission costs you the deposit and the lead time together.
Now the other half of the market, which is most of it. In Goose Creek, Hanahan, Ladson, Sangaree, Moncks Corner and the Summerville subdivisions there is no architectural review over windows at all, and vinyl is frequently the correct answer rather than the cheap one. Nobody is going to make you justify a frame material in Sangaree.
A welded vinyl frame does not corrode, which matters more here than it does inland. It never needs paint, which on a two-story gable end nobody wants to reach is a genuine saving. In a rental, on a flip, or on a house you plan to leave inside five years, spending clad-wood money buys you very little you will ever see back. The resale sheet does not itemize your frame material.
The things that separate a decent vinyl unit from a bad one are unglamorous. Look for reinforcement in the meeting rail and in any sash over about three feet wide, fusion-welded rather than mechanically fastened corners, metal-reinforced sliding tracks, and a balance system with a part number you can still buy in ten years. Dark exterior colors want capstock, not paint, because painted vinyl absorbs heat and bows.
We quote it plainly and we tell you where it stops making sense: large fixed spans, anything above roughly six feet in a single sash, and any elevation where the frame will be seen against a masonry opening. Those are the places to spend more. Everywhere else, vinyl does the job and we will not talk you out of it.
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 vinyl windows
The difference between vinyl windows that lasts and vinyl windows 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
