About Charleston Window Pros: Licensed Window Pros in SC
Charleston Window Pros works the whole Lowcountry, but the company was built around a peculiarity of this city: the same house can legitimately need two different windows, because the Board of Architectural Review's authority follows sightlines from the public right-of-way rather than property lines. Everything we do starts by drawing that line on paper before anyone talks about a brand.
That means the estimate is organized by elevation and by opening, not by house. It means we produce the window schedule and the repair photographs the adopted policy asks for rather than leaving a homeowner to assemble them. And it means we quote the cheap fix first when the cheap fix is the right one, which on original Charleston sash it usually is.
Do not hire us if you want a single price for twenty-two identical windows and no paperwork. On a peninsula address that quote is a fiction and always has been, and anyone who hands it to you has not read the policy. If you are outside the districts and you want a straight product-and-labour number with no review at all, say so, and that is exactly what you will get.
If you have a window project in Charleston, the fastest way to get a real number is a free on-site estimate. See every Charleston service we handle, check whether we cover Mount Pleasant, SC and the rest of the South Carolina Lowcountry, or go back to the Charleston Window Pros homepage to start. You can also reach us directly on (844) 511-2320.
Credentials
- License: Residential work is licensed through the South Carolina Residential Builders Commission. Commercial glazing is licensed separately by the South Carolina Contractor's Licensing Board under the Glass and Glazing classification of Section 40-11-410, the classification that names curtain wall, mall fronts and architectural window systems
- Insurance: General liability and workers compensation on every crew, with the certificate mailed to the property owner by the carrier rather than forwarded as a scan from our own file
- Association: Units are specified by their AAMA/WDMA/CSA 101/I.S.2/A440 ratings, and any opening protection we quote is tested to ASTM E1886 and ASTM E1996, the missile-impact standards the South Carolina Building Code points to
- Warranty: a written workmanship warranty covering the installation, kept separate from the manufacturer's glass and hardware coverage so a sealed-unit claim never gets tangled up with a flashing claim
How Charleston Window Pros works
How a job with Charleston Window Pros runs, start to finish
Site visit first, always. We measure, look at the real condition of the work area, and ask what you are actually trying to solve — then you get an itemized free estimate in writing with materials, scope and a realistic date on it.
Once the work starts, the same crew stays on the job until it is done. We protect the surrounding area, clean up daily, and tell you the moment something under the surface changes the plan, because the alternative is a surprise invoice and nobody wants that conversation. a written workmanship warranty covering the installation, kept separate from the manufacturer's glass and hardware coverage so a sealed-unit claim never gets tangled up with a flashing claim backs the finished work.
What we will not do
We do not quote a window job over the phone, take deposits before a written scope exists, or bid work we are not set up to do properly. If your project needs a different trade, we say so and point you at someone who does it well. Losing a job is cheaper than doing one badly in Charleston.
Where Charleston Window Pros works and who we work with
Charleston, SC first, then the surrounding communities of the South Carolina Lowcountry: Mount Pleasant, North Charleston, Summerville, Goose Creek, Hanahan, Ladson, James Island, Folly Beach and more. Each of those has its own page with local detail rather than a copy of this one.
Work splits roughly between homeowners and commercial property — offices, retail, restaurants, apartment complexes and HOA boards across the South Carolina Lowcountry. Start with the Charleston services, the Charleston Window Pros homepage, or just call (844) 511-2320.
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
- ✓Repair-versus-replacement documented with photographs and a written schedule, because the policy requires evidence and staff can ask for a site visit before deciding
- ✓Hardware specified separately from the unit, since a harbor-facing elevation and a walled courtyard elevation on the same house do not corrode on the same timetable
What Charleston Customers Say
We had two quotes for the whole house at one number and no mention of review. These guys came out, walked the lane behind us, and showed us that four openings were visible from it and eleven were not. The eleven got a clad unit, the four got repaired sash and a storm panel. Total came in under both of the other quotes.
Straightforward job, no review, no drama. They measured every opening rather than assuming the builder used one size, which turned out to matter on the two upstairs bedrooms. Egress numbers were written on the quote. Installed in a day and a half and cleaned up the mulch bed afterwards.
Called about condensation between the panes on eight windows and expected to be sold a whole-house replacement. They swapped the sealed units in the existing frames and replaced two failed balances. About a quarter of what I had braced for. They also told me which two frames really are near the end and to budget for those.
Salt eats hardware out here and every previous installer ignored it. This crew specified the rollers and fasteners as a separate line item and explained why the ocean side and the marsh side of the house were getting different parts. Sliders still run with one finger after two seasons.
