Commercial doors
We install and repair sectional, rolling steel and fire-rated garage doors for shops, warehouses, storage facilities and municipal buildings across Oconee County. We also service commercial operators and loading dock equipment.

Commercial door types
The number of times a door opens each day determines the right springs, track and operator. Compare the main commercial door types below.
Steel sections run on horizontal track and are available with insulation and windows. Damaged panels can usually be replaced without replacing the entire door. Heavier steel and wind-rated options are available for exposed buildings.
Service bays, warehouses, fleet garages and fire stations.
Interlocking steel slats coil into a hood above the door, so no ceiling track is needed. Individual slats can be replaced after damage. Rolling steel doors also support high cycle counts.
Openings with no ceiling room, secure storefronts and stockrooms, self-storage buildings and exterior security closures.
Aluminum frames are available with clear, tinted or polycarbonate panels. These doors bring daylight into the building and provide visibility from outside. Their lower weight also reduces strain on the operator and springs.
Dealerships, restaurants, breweries, gyms and customer-facing service bays.
These rolling steel doors close automatically when triggered by an alarm or fusible link. Many rated wall openings require them. We install the doors and provide the annual drop testing and documentation required by NFPA 80.
Rated openings in mixed-use buildings, parts rooms and parking structures.
Fabric curtains travel up to 60 inches per second and can reset after minor impacts. They reduce conditioned-air loss and keep traffic moving through doors that open frequently.
Cold storage, food processing, car washes and busy interior openings between conditioned zones.
Prices are typical installed ranges for openings from 10 by 10 ft to 12 by 12 ft. We provide a site-specific quote for larger openings, wind-rated doors and high-lift track.
Commercial operators
Commercial doors need operators rated for their size and daily use. We install LiftMaster commercial operators with the controls and safety devices your facility needs.
These operators mount on the ceiling and work with standard-lift sectional doors. They are a good fit for service bays and shops with clear ceiling space.
These operators mount on the wall at the torsion shaft. They work with high-lift track, full-vertical track and rolling steel doors while leaving the ceiling clear.
These operators include a chain hoist for manual operation during a power outage. They are used on heavy openings and many fire-rated doors.
