Window replacement in Mount Pleasant, SC
Impact-rated and energy-efficient replacement windows set plumb, shimmed on full support, and flashed into a sloped pan. We measure every opening before recommending insert versus full-frame — there is no single right answer for a whole house.
Working in Mount Pleasant
What this house, on this street, actually needs.
Mount Pleasant runs from Old Village cottages a few hundred feet off the harbor to twenty-year-old subdivisions in Park West and Carolina Park where the original builder-grade envelope is now reaching the end of its service life. Most of what we're called for here is first-replacement work — the original roof, windows, or siding finally giving up at the same time.
Original builder windows across Mount Pleasant's larger neighborhoods are now at end of life — fogged glass, failed balances, sashes that won't lock. Most of these openings are square and sound, so inserts do the job; we still verify before recommending them.
HOA rules here usually govern work hours, dumpster placement, and material staging. We get those in writing before day one so the schedule we give you is the schedule you get.

Mount Pleasant FAQs
Straight answers before you commit.
Do you need a permit for windows work in Mount Pleasant?
Mount Pleasant issues its own building permits through the town, and most planned communities add an architectural review committee on top of that. We handle both — the town submittal and the ARC package with product, color, and profile documentation. We pull the permits in our name and provide inspection records with your closeout documents.
What makes windows in Mount Pleasant different from inland work?
Heat gain and water intrusion are the two failures here. Low-E coatings cut the summer load, and a properly sloped, flashed pan means the water that inevitably gets past a sealant joint drains back outside instead of soaking the rough opening.
Which Mount Pleasant areas do you serve?
We work throughout Mount Pleasant, including Old Village, I'On, Park West, Carolina Park, and the surrounding Lowcountry. Our office is at 668 Marina Dr Unit B7 in Charleston.
Are you licensed and insured to work in Mount Pleasant?
Yes. We carry general liability and workers' compensation coverage, pull permits under our own license, and provide certificates on request before work begins.
How long does a window replacement project take?
Installation is usually one to three days for a whole house. The longer part is the order — custom and impact-rated units typically run four to ten weeks from approval, and we give you that date up front.
Do I need impact-rated glass?
It depends on your exposure and wind zone. We'll tell you which elevations genuinely justify the cost and where a strong Low-E package is the smarter spend. We don't blanket-upsell impact on every opening.
