Commercial Overhead and Rolling Steel Doors in Flower Mound

A commercial door cycles ten times as often as a residential one, on a building where the door is the security. The failures are the ones a house gets, springs, cables, rollers, track and operators, but they arrive sooner, and a dock door down at 6 a.m. holds a truck in the lot and a shift at the bay. Commercial work in Flower Mound is quoted per door after the tech has seen it.

Doors we service

• Sectional steel doors on warehouses, shops, auto bays and self-storage. Insulated and non-insulated, with or without vision panels.
• Rolling steel doors and service doors where the ceiling cannot take a horizontal track.
• Dock doors with bumpers, seals and dock levelers on the same opening.
• High-lift and vertical-lift doors in bays with tall clear height.
• Fire station and municipal doors that need fast, reliable cycling.
• Counter shutters and security grilles on storefronts.
• Commercial operators: jackshaft, trolley and hoist units, with photo eyes, edge sensors, timers to close and keypad or loop detector controls.

Common commercial failures

Springs on a commercial door are sized for the door and rated for a cycle count. A busy bay door that cycles 50 times a day uses a 10,000-cycle spring in less than a year. We size replacement springs for the real usage, and high-cycle springs rated for 50,000 or 100,000 cycles usually pay for themselves in avoided calls.

Cables fray at the drums and bottom brackets. Rollers flatten under heavy sections. Track gets hit by forklifts and pallets, and a bent track is the most common reason a commercial door jams. Operators strip gears or burn out when the door goes out of balance, same as at home but with larger motors. Photo eyes and edge sensors get knocked out of line by the same forklifts, and a door that will not close on a timer is usually a sensor, not the operator.

Doors that face the weather lose bottom seals and jamb seals, which raises heating and cooling costs and lets water into the bay.

What a commercial service visit looks like

The tech checks balance first by lifting the door with the operator released. Then springs, cables, drums, rollers, hinges, track, bottom bar and every safety device. You get a written findings list with prices, and repairs that can be done from the truck are done that visit. Larger sections and operators are ordered and installed on a return visit scheduled around your hours.

For new openings we measure for clear height, side room and headroom, and specify the door, operator and controls. Most Denton County cities treat a like-for-like garage door or opener replacement as repair work that does not need a building permit, while a new or enlarged opening, header work or a commercial door usually does. We confirm with your city before ordering and pull the permit when one applies.

Pricing and contracts

Quoted per door after an on-site inspection, with the service call applied to the repair. Buildings with several doors get a per-door rate on maintenance visits, and a maintenance contract moves your building to priority scheduling for breakdowns. Proof of insurance and the written findings list come with every visit.

Have the door count, the bay hours and the operator brand ready when you call (469) 947-3776. That is enough to quote a maintenance visit or send a tech to a stuck dock door.
