Rolling Steel & Sheet Door Repair in Naples, FL
Get A Free Estimate
In the commercial sector, space is money. That is why Roll-Up Doors (Coiling Doors) are the standard for Naples warehouses, loading docks, and retail storefronts. They coil up tightly above the opening, leaving the ceiling clear for lighting, sprinklers, and HVAC systems.
But when a roll-up door jams, it creates an immediate crisis. You cannot secure your inventory at night and ship goods during the day. At Garage Door Naples, we specialize in the repair and installation of both Heavy-Duty Rolling Steel and Light-Duty Sheet Doors. We carry specialized tools, including chain hoists and tension wheels, to safely service these high-tension systems.
Heavy-Duty Solutions for Industrial Security
Unlike sectional doors which hang from the ceiling, rolling doors are self-contained. This makes them tougher, but harder to fix without training. We service all major manufacturers, including Cornell, Cookson, Janus, DBCI, and Wayne Dalton. Whether your door is manually operated by a chain hoist or automated with a heavy-duty motor, we can get it moving again.
Rolling Steel vs. Sheet Doors: What Do You Have?
Common Roll-Up Door Repairs We Perform
Broken Spring Barrel & Tension Problems:
Rolling doors don’t use visible springs like residential doors. The springs are hidden inside the metal barrel at the top. When these break, the door becomes “dead weight” (hundreds of pounds) and won’t lift. We disassemble the barrel to replace the internal torsion springs.
Warning: Never try to adjust the tension on a rolling door yourself. The stored energy is lethal.
Damaged Slat Replacement (Forklift Impact):
Accidents happen. If a driver backs into a closed rolling steel door, the bottom bar usually bows and several slats bend. We stock standard 22-gauge and 20-gauge galvanized slats to swap out the damaged section, restoring the door’s operation and security.
Off-Track & Jammed Curtains:
If a door is closed on an obstruction, the curtain can “cone” or jump out of the vertical guides. We use chain falls and leverage tools to force the curtain back into the guides and realign the barrel.
Rolling Fire Doors: NFPA 80 Drop Testing
If you have a rolling door between your warehouse and your office, or in a firewall, it is likely a Rated Fire Door. By law (NFPA 80), these must be inspected and tested annually.
Our Service: We perform the official “Drop Test.” We disconnect the governor and allow the door to close under gravity/spring tension to ensure it seals the opening during a fire.
Certification: We provide the written documentation required by the Naples Fire Marshal and your insurance carrier.
Security Grilles & Storefront Gates
For retail stores in Coastland Center or Mercato, visibility is key. We repair Rolling Security Grilles (the “jail bar” or open-link style gates).
Common Issues: Broken links, motor failure, or the grille getting stuck in the overhead soffit.
Emergency Service: If your grille won’t open, you can’t open your store. We prioritize retail calls to get you open for business ASAP.
Self-Storage Facility Maintenance Programs
Do you manage a self-storage complex with 500+ doors? We offer bulk maintenance plans for Janus and DBCI sheet doors.
The Service: We walk the property, adjust spring tension on hard-to-open doors, grease the guides, and replace broken latches or ropes.
The Benefit: Happy tenants who pay rent on time because their unit door actually works.
Wind Load Rated Coiling Doors
In Naples, standard rolling doors can blow out during a hurricane, pressurizing the building and destroying the roof. We install Wind-Load Rated rolling doors. These have “Windlocks” (heavy iron clips) riveted to the ends of the slats that lock into the door track, preventing the curtain from being pulled out by 150+ MPH winds.
Motorizing Your Manual Chain Hoist
Tired of your employees wasting 5 minutes every morning pulling a hand chain to open a 14-foot door? We can retrofit your existing rolling door with a Jackshaft Operator.
Efficiency: Opens the door in seconds with the push of a button.
Safety: Eliminates back injuries from employees straining to lift heavy doors.
Frequently Asked Questions About Roll-Up Doors
Can you replace just the damaged slats on my rolling door?
Yes, if it is a Rolling Steel door (interlocking slats). We can remove the bottom bar, slide out the bent slats, and insert new ones. This is much cheaper than a new door. If it is a Sheet Door (one piece), the whole curtain usually must be replaced.
Why is my roll-up door so hard to lift?
This indicates a loss of Spring Tension. The internal springs in the barrel counteract the weight of the door. Over time, steel relaxes. We can add tension to the spring wheel to make the door feel light again. Do not attempt this yourself; it is dangerous.
How often do fire doors need to be tested? .
Annually, NFPA 80 standards require a visual inspection and an operational Drop Test once per year. You must keep these records for the Fire Marshal.
What is the difference between a service door and a fire door?
A Service Door is designed for daily use (security/access). A Fire Door is designed to stay open and only close when a fire alarm is triggered (though some “Service Fire Doors” do both). Fire doors have fusible links and governor mechanisms that service doors do not.
Do you repair storage unit doors?
Yes. We service Janus, DBCI, and Trac-Rite sheet doors common in self-storage. We fix broken latches, retention springs, and dented tracks.
