About CDF Distributors

How often should commercial door hinges be lubricated?

Lubricate commercial door hinges quarterly using a lithium-based or PTFE lubricant. High-frequency doors (hospitals, schools, retail) may require monthly lubrication. Apply lubricant to the hinge pin and work the door through its full swing to distribute.

Is NFPA 80 annual inspection required for all fire doors?

Yes. NFPA 80 requires annual inspection of all fire door assemblies. The inspection must be documented and records must be retained. Many jurisdictions enforce this requirement through fire marshal inspections. The inspection verifies self-closing, positive latching, clearances, labels, and absence of modifications.

What is the most commonly overlooked maintenance item?

Weatherstripping is the most commonly overlooked item. Deteriorated weatherstripping allows air infiltration, increases energy costs, and reduces sound isolation. Inspect weatherstripping quarterly and replace when it shows compression set, tears, or detachment.

Can building maintenance staff perform NFPA 80 inspections?

NFPA 80 requires that inspections be performed by individuals with knowledge of the operating components of the door assembly being inspected. Building maintenance staff can perform the inspection if they have the necessary training. Some facilities use third-party door inspection companies.

How long do door closers last?

A quality commercial door closer typically lasts 10-15 years under normal use. High-frequency doors (hospitals, schools) may require closer replacement every 5-7 years. Replace a closer when it leaks fluid, cannot be adjusted to proper speed, or fails to latch the door consistently.

Frequently Asked Questions

Configure Your Door Assembly

Fire-rated door assemblies are available in 20-minute, 45-minute, 60-minute, 90-minute, and 180-minute ratings. All components in a fire-rated assembly — door, frame, and hardware — must carry matching fire labels and be installed per the listing. Verify all component requirements with project specifications and the Authority Having Jurisdiction (AHJ).

A Note on Fire-Rated Assemblies

CDF can source replacement maintenance components including weatherstripping, thresholds, door sweeps, closers, and hinges. ProBuilder tracks assembly specifications for reordering — provide the original order number or assembly configuration, and CDF can identify exact replacement parts to maintain the original specification.

CDF Maintenance Component Support

Maintenance documentation serves as proof of compliance and helps identify recurring issues.

• Record the date, inspector name, and building/floor/opening number for each inspection

• Note pass/fail for each checklist item

• Document any deficiencies found and the corrective action taken or scheduled

• For fire-rated assemblies: retain annual inspection reports for the life of the installation

• Provide copies of inspection results to the building owner or property manager

Documentation Requirements

Annual checks include all monthly and quarterly items plus a comprehensive inspection. Allow 20-30 minutes per door. For fire-rated assemblies, this check aligns with the NFPA 80 annual inspection requirement.

Fire Door Annual Inspection (NFPA 80)

Fire-rated door assemblies must be inspected annually per NFPA 80. Fire-rated assemblies are available in 20-minute, 45-minute, 60-minute, 90-minute, and 180-minute ratings. The annual inspection must verify the following.

• All fire labels present and legible on door, frame, hardware, and glazing

• No unauthorized modifications to any component

• Self-closing test: door closes and latches from full open position

• Positive latching test: door cannot be pulled open without hardware activation

• Clearance measurements within NFPA 80 limits (1/8 inch maximum at sides and top)

• Gasketing intact and in continuous contact

Closer Annual Service

• Test and adjust closing speed, latching speed, and backcheck

• Check for fluid leaks at the closer body — replace closer if leaking

• Verify ADA sweep time compliance (minimum 5 seconds from 90 to 12 degrees)

Hardware Annual Service

• Tighten all hardware mounting screws (hinges, lockset, closer, stops)

• Test all lock functions and verify key operation

• Inspect panic hardware components for wear and test operation

Finish and Structure

• Inspect door and frame finish for corrosion, peeling, or wear — repaint if needed

• Assess sealant and gasket condition at frame perimeter — reseal if deteriorated

• Check glazing seals (if applicable) for failure or moisture intrusion

• Document all inspection results and retain for compliance records

Annual Maintenance Checks

Quarterly checks include all monthly items plus detailed inspection of wear components. Allow 10-15 minutes per door.

• Hinge inspection: check for excessive play, loose screws, and corrosion — tighten all hinge screws

• Hinge lubrication: apply lithium-based or PTFE lubricant to all hinge pins and knuckles

• Weatherstripping condition: inspect all weatherstripping for compression set, tears, gaps, and detachment — replace if deteriorated

• Threshold condition: check for loose anchoring, wear, and damage — verify the door sweep contacts the threshold evenly

• Frame integrity: check for frame movement, loose anchors, and cracked sealant at the frame-to-wall joint

• Closer arm: check for wear at pivot points and verify all connections are tight

• Door edge and bottom: check for damage, swelling, or delamination

• Record results and schedule repairs for any deficient items

Quarterly Maintenance Checks

Monthly checks focus on basic operational verification. These checks can be completed in 2-3 minutes per door by building maintenance staff.

• Door operation: open and close the door — it should move smoothly without binding, sticking, or scraping

• Closer function: release the door from 90 degrees — it should close at a controlled speed and latch without slamming

• Panic hardware test (if equipped): push the bar across its full width — the latch should retract and the door should open freely

• Lockset operation: test key lock and unlock; test all lock functions (thumbturn, push-button, indicator)

• Visual check: look for visible damage, loose hardware, or missing components

• Self-closing check (fire doors): verify the door closes and latches from both 90 degrees and 30 degrees without assistance

• Record results and note any items requiring further attention

Monthly Maintenance Checks

Commercial doors are operated hundreds of times per day. Without scheduled maintenance, hardware wears, closers lose adjustment, weatherstripping deteriorates, and fire-rated assemblies fall out of compliance. A documented maintenance program extends component life, reduces emergency repairs, and maintains code compliance.
