Door replacement in Charleston, SC
Entry, patio, and sliding door systems set plumb on a flashed sill pan with continuous weatherstripping and an adjustable threshold — so the door operates the same in year five as it did on day one.
Working in Charleston
What this house, on this street, actually needs.
Charleston is not one building stock, it's four. Peninsula single houses with century-old framing, 1950s West Ashley ranches, James Island cottages, and new construction on filled ground — each one fails differently. We scope the house in front of us instead of applying one spec to the whole county.
Peninsula entry doors sit close to grade and take direct wind-driven rain off the harbor. Elevated island homes have the opposite problem — exposed slabs and landings that need proper pans and thresholds to keep water from tracking in.
Peninsula addresses mean narrow streets, shared driveways, and limited dumpster placement. We plan staging and street access up front so your neighbors aren't part of the project.

Charleston FAQs
Straight answers before you commit.
Do you need a permit for doors work in Charleston?
Work inside the City of Charleston is permitted through the city's permit center, and anything in a designated historic district can require Board of Architectural Review approval before materials are ordered. We confirm which track your address falls under before we quote a lead time. We pull the permits in our name and provide inspection records with your closeout documents.
What makes doors in Charleston different from inland work?
Coastal humidity swells wood slabs and salt air eats plated hardware. We specify fiberglass or clad units and stainless or coastal-rated hardware, and we pan-flash every sill so storm-driven water drains outward.
Which Charleston areas do you serve?
We work throughout Charleston, including Downtown peninsula & South of Broad, Wagener Terrace & Hampton Park, West Ashley, James Island, and the surrounding Lowcountry. Our office is at 668 Marina Dr Unit B7 in Charleston.
Are you licensed and insured to work in Charleston?
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 door installation take?
A single entry or patio door is typically one day. Multiple units, a large slider, or structural work runs two to three days. Custom units carry a four to ten week lead time from order.
Why do doors start sticking after a year?
Almost always an unsupported shim stack or a sill that wasn't set level. We set on full shim support with a sloped pan, then do a final adjustment pass — and re-adjust free within the workmanship warranty period.
