Charleston Window Pros provides professional french and piazza doors in Charleston, SC for residential and commercial properties across the South Carolina Lowcountry. French doors belong to Charleston in a way they do not to most American cities, because the building type demands them. The single house turns its narrow end to the street and runs a piazza down its long flank, and the rooms open onto it through glazed doors.
That piazza is not a porch bolted on for looks. It is a shading device and a breezeway, and the doors along it were built to work with it: tall, glazed, opening wide to move air through a house that had no other way of cooling itself. Some of the openings are jib windows, triple-hung sash that lift high enough to walk straight through.
So on a historic house our advice usually runs the other way from a sales pitch. Repair what is there. Old cypress and heart-pine doors with hand-worked moldings and putty-glazed lites are better made than anything in a modern catalog, and the parts that fail are the hinges, the astragal and the sill, all of which are replaceable without touching the stiles and rails.
Where replacement is genuinely warranted in a reviewed district, the same matrix rules apply as for windows. Fifty years or older means wood with true divided lites matching material, grid, muntin dimension and profile. A stock door with grilles sandwiched between the panes will not do, and the policy says as much: grilles between glass are not approved. That single line rules out most of what sits on a showroom floor.
The technical decision on any pair of french doors is swing. Out-swing seals better against wind-driven rain, because the pressure pushes the leaves onto the stop instead of off it, which in this climate is worth real money. It also puts the hinges outside, so it needs non-removable pins, and it needs the piazza clear of furniture where the leaves swing.
In-swing is friendlier to a narrow piazza and to furniture on it, but it wants a proper threshold with an adjustable sweep and a good sill pan under it, and it will pass water sooner in a driven storm. On an exposed elevation we lean out-swing and on a sheltered courtyard we lean in-swing, and we will tell you which yours is.
Hardware carries the whole assembly. A multi-point lock that throws at three heights keeps a tall leaf flat and stops the seasonal binding that plagues french doors. Flush bolts on the inactive leaf need a properly drilled strike in the threshold, not a hole punched after the fact. Coastal exposure means stainless or solid bronze rather than plated, and it means checking the lock body as well as the visible trim.
One thing we insist on: hang tall doors before the finish floor is committed, and shim the hinge jamb dead plumb. A pair of eight-foot leaves shows every sixteenth of an inch at the meeting stile, and a gap that opens toward the top is a hinge-jamb problem that no amount of adjusting the strike will hide. Hang them properly once and they stay right for thirty years.
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 french and piazza doors
The difference between french and piazza doors that lasts and french and piazza doors 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
