Garage Door Replacement in Charleston, SC

Wind-rated and BAR-compliant garage door replacement in Charleston

Replacing a complete garage door in Charleston or Charleston County is treated as a structural exterior opening replacement, not a cosmetic swap. Inside the City of Charleston, replacement garage doors require a Building Inspections permit (Residential Window and/or Door Replacement application) and must be rated for the City's 150 mph coastal wind-design speed. Across Charleston County, Building Inspection Services requires a building permit with the County's Windows and Doors Form showing that the door has been tested to ASTM E330 or ANSI/DASMA 108 and bears a permanent manufacturer label listing the model/series, positive and negative design wind pressure (DP) rating, installation instruction drawing reference, and test standard.

If your property lies inside the City of Charleston's Old and Historic District, Old City District, or Historic Corridor District and the garage or carriage house is visible from a public street, lane, or right-of-way, the replacement door also requires review by the Preservation Division staff or the Board of Architectural Review (BAR-S for projects under 10,000 sq ft) before the building permit is issued. Historic districts typically favor authentic wood or paint-grade composite carriage-house doors with traditional stile-and-rail proportions and impact-rated or properly muntined glazing over stamped steel panels.

For drive-under elevated homes and attached garages in West Ashley, James Island, Johns Island, North Charleston, and Mount Pleasant, three-layer polyurethane-insulated steel or aluminum coastal doors with heavy-gauge tracks and integrated wind-load struts help keep humid summer heat out of living spaces directly above the garage bays.
