Expert Fire Door Services Throughout California
Fire doors are one of the most critical passive fire protection features in any commercial building. When a fire breaks out, properly functioning fire-rated door assemblies compartmentalize the structure, slowing the spread of flames and smoke to give occupants more time to evacuate safely. At Delta Fire Equipment, we provide comprehensive closing assembly and fire door services that keep your building compliant with California fire codes and NFPA 80 standards.
With over 30 years of experience serving commercial properties throughout California, our certified technicians understand the unique requirements of fire door assemblies in high-rise buildings, hospitals, schools, hotels, and industrial facilities. Every inspection, repair, and certification we perform follows the strict guidelines set forth by NFPA 80, the Standard for Fire Doors and Other Opening Protectives, and the California Building Code.
Fire Door Inspection & Certification
NFPA 80 requires annual inspections of all fire door assemblies to verify they are in proper working condition. Our certified inspectors conduct thorough evaluations that cover every aspect of the fire door assembly, including the door itself, the frame, hardware, glazing, and closing mechanisms. Each inspection produces a detailed report documenting the condition of every component, identifying deficiencies, and recommending corrective actions.
Our inspection process includes verifying that fire-rated labels are intact and legible, checking that doors close and latch properly from any open position, inspecting gaskets and edge seals for damage, confirming proper clearances around the door perimeter, and ensuring no field modifications have compromised the fire rating. Upon successful completion, we provide a certification document that satisfies the requirements of your authority having jurisdiction (AHJ) and insurance carrier.
Closing Mechanism Repair & Replacement
The closing mechanism is the heart of any fire door assembly. Whether your building uses overhead door closers, floor-mounted closers, concealed closers, or electromagnetic hold-open devices, our technicians are factory-trained to service, adjust, and replace every type. We carry a comprehensive inventory of closing hardware from leading manufacturers, enabling us to complete most repairs in a single visit.
Common issues we resolve include doors that fail to close completely, closers with inconsistent closing speeds, backcheck mechanisms that are too stiff or too loose, hold-open devices that do not release upon fire alarm activation, and worn pivot assemblies. Properly adjusted closing mechanisms ensure the door will perform exactly as designed during a fire event.
Drop Testing Services
Fire doors equipped with fusible links, electromagnetic holders, or automatic-release mechanisms must be periodically drop tested to confirm they will close reliably when activated. Our technicians conduct controlled drop tests by simulating fire alarm activation and verifying that the door travels to a fully closed and latched position. We document closing time, latch engagement, and any obstructions or mechanical issues that could prevent proper closure.
Drop testing is especially important for rolling steel fire doors, fire shutters, and horizontal sliding fire doors commonly found in warehouses, parking structures, and commercial kitchen pass-throughs. California fire marshals increasingly require documented drop test results as part of annual compliance inspections.
Hardware Upgrades & Retrofits
Building codes evolve, and older fire door assemblies may need hardware upgrades to meet current standards. Delta Fire Equipment helps property managers and building owners plan and execute hardware upgrade programs that bring fire doors into compliance without full door replacement. Our upgrade services include installing new self-closing devices, replacing outdated exit hardware with modern panic devices, adding smoke gaskets and intumescent seals, upgrading to UL-listed hinges, and retrofitting electromagnetic hold-open devices tied to the fire alarm system.
We work closely with door manufacturers to ensure that any modifications we make do not void the fire rating of the assembly. All replacement hardware is UL-listed and meets the specifications required by the original door listing.
