Common hinge repairs: replacement of worn ball-bearing hinges on office doors, continuous hinge installation on high-abuse doors (school corridors, hospitals), pivot hinge service on storefronts, and mortise repair after forced entry or vandalism. Each application requires specific hinge types and installation approaches.

Commercial hinge types, failures, and repair
Commercial hinges come in several categories based on mounting, bearing type, and construction. Each has specific applications and failure modes.
Butt Hinges: Standard commercial hinges mounting to door and frame. Available in several configurations:
• Plain bearing - light-duty, residential and light commercial
• Ball-bearing - commercial standard for high-traffic doors
• Oil-impregnated bearing - maintenance-free option
• Hospital tip - sloped tops prevent ligature points in mental health facilities
Continuous Hinges: Full-length hinges spanning the entire door height. Distribute load along the full length rather than concentrating at 3-4 points. Advantages: no sagging, can't be easily pried off, excellent durability.
Disadvantages: higher cost, more complex installation. Standard for schools, hospitals, high-abuse doors. Stanley, Select, and Bommer are common manufacturers.
Pivot Hinges: Instead of butt hinges along the edge, pivot hinges at top and bottom of the door allow rotation around a vertical axis. Common on aluminum storefronts, decorative doors, and doors that need to open past 90°. Different failure modes than butt hinges - pivot bearings wear out requiring replacement.
Spring Hinges: Self-closing hinges with internal springs. Used where fire code requires self-closing but a full closer isn't needed. Less common than closers but useful in specific applications.
Common Failures:
Bearing Wear: Ball bearings wear after high cycle count. Door develops play, squeaks, and eventually sags. Replacement with new ball-bearing hinges restores operation.
For very high-traffic applications, upgrade to continuous hinge prevents recurrence.
Screw Pullout: Long-term wear causes screws to loosen and pull out of the wood or metal frame. Door sags or binds. Repair with longer screws reaching into solid material, sometimes with epoxy or wood plugs to strengthen mount.
Mortise Damage: Forced entry or impact damages the hinge mortise (pocket where hinge mounts). Wood frames can be patched with wood plugs and glue. Metal frames require welding to restore material.
Knuckle Wear: The pivot knuckles on butt hinges eventually wear, creating play. Replacement is the only repair - worn hinges can't be rebuilt in-field.
Fire Door Requirements: Fire-rated doors require ball-bearing hinges. Plain bearing hinges aren't compliant. Must be UL-listed for fire application.
Minimum 3 hinges for doors up to 7'6" height, 4 hinges for taller.
Security Considerations: Outswing doors have exposed hinge pins vulnerable to pin removal attacks. Security hinges with non-removable pins or set screws prevent this. Anti-pry hinges resist lifting attacks on outswing doors.
Important for exterior outswinging doors.

Why is my door sagging?
Usually worn or loose hinges. Check for loose screws first - sometimes just tightening corrects sag. If screws are pulling out or hinges are worn, replacement is needed.
Long-term sag damages the frame, so address promptly.
Can you install continuous hinges?
Yes. Continuous hinge upgrade for high-traffic or high-abuse doors. Schools, hospitals, corridor doors, and heavy-use commercial applications benefit most.
Higher upfront cost but much longer life than standard butt hinges.
What about fire-rated hinges?
Fire doors require UL-listed ball-bearing hinges. Typically 3 hinges minimum for standard doors, 4 for tall doors. Replacement uses matching UL-listed hinges to preserve fire rating.
Standard service for fire door repair.
Can you fix a forced-entry damaged hinge mortise?
Yes. Mortise repair with welding for metal frames, wood patching for wood frames. Restores hinge mounting surface and allows new hinge installation.
Common post-break-in repair.
Do you service pivot hinges?
Yes. Storefront door pivots, heavy commercial pivots, and specialty pivot hinges serviced. Pivot bearings wear after 5-10 years and need replacement.
Different from butt hinges - specific repair approach.
What about anti-pry security hinges?
Yes. Security hinges for outswinging exterior doors prevent pin removal and pry attacks. Recommended for all outswinging commercial doors.
Common upgrade during rekey or lock replacement.
Can you match existing hinge finish?
Yes. Common finishes (brass, chrome, black, bronze, nickel) matched to existing hardware. Tell us the finish during scheduling so we can arrive with matching parts.
How long do commercial hinges last?
Ball-bearing hinges in normal commercial use: 10-20 years. High-traffic applications: 5-10 years. Continuous hinges: 15-30+ years.
Replace when bearing wear causes door problems or screws won't hold.
Do you handle heavy solid wood doors?
Yes. Solid wood doors (church, historic building, executive office) need heavy-duty hinges. Larger ball-bearing or continuous hinges rated for door weight.
Specification during service call.
What if my frame is damaged where hinges mount?
Frame repair may be needed before hinge replacement. Minor damage patched with wood plugs or welded for metal. Severe damage may require frame section replacement.
We evaluate during site visit.
Can you correct door binding?
Yes. Binding is usually hinge-related (sag from worn hinges) or frame-related (shift from settling). Diagnosis during service visit determines repair.
Most binding issues resolved in 1-2 hours.
