Hotel stairwell doors, school classroom doors, multi-tenant apartment corridor doors, commercial back-of-house doors - all labeled fire doors require UL-listed fire-rated hardware. We install UL 10C compliant locks on labeled openings, preserve the door's fire rating per NFPA 80, and document everything for your fire-marshal inspection.
Fire door lock installation in Port St. Lucie - UL-listed locks on UL-labeled fire doors. NFPA 80 compliance, label preservation, fire-marshal documentation.
Common installs: hotels and motels along US-1, PSL schools (St Lucie County School District), multi-tenant apartment buildings, hospital corridor doors, commercial back-of-house.
Cost $320-720 per door depending on grade and complexity. Inspection documentation included free with our installs.
A UL 10C or UL 10B fire-rated door assembly is a system. If any one piece (lockset, hinges, closer, smoke seal, latch throw) is wrong or damaged, the whole rating is void and the fire-marshal cites you. We get called constantly after annual inspections at the medical and office buildings around the St Lucie West corridor and at the older commercial blocks near downtown Fort Pierce.
The most common citations: non-rated lock retrofitted onto a rated door, latch bolt that does not throw the required 3/4 inch, closer missing or not self-closing under spring, smoke seal stripped off, non-labeled hinges, and field-cut holes through the rated assembly. Each is a documented fix with photos for your inspector.
UL-listed locks, hinges, and closers stocked. Call (772) 284-5142 for a same-day site visit before your re-inspection deadline.
Every piece we install on a fire-rated assembly is UL 10C or UL 10B listed and tagged. We do not retrofit non-rated hardware onto rated doors.
UL-listed lockset swap around $380. Full hardware package (lock + closer + hinges + seal) on a single rated door around $680 to $780.
We work on Steelcraft, Curries, Republic, and older Mesker fire-rated assemblies. The lock prep on each is slightly different.
We measure the actual latch throw after install. The required 3/4 inch minimum is non-negotiable for the rating.
Tell us your re-inspection date. We schedule fire-door work to clear before the deadline so you avoid citation fees.
Written work order with UL listing numbers, lock serial numbers, and photos. Hand it to the fire marshal at re-inspection.
General handymen will void your rating without knowing. Big door companies subcontract this to locksmiths anyway. We are the direct hire.
NFPA 80, FBC chapter 7, and FFPC. We will tell you what the inspector is going to flag before he flags it.
Schlage L9000, Falcon T-series, LCN 4040SE closers, and labeled Stanley FBB191 hinges in fire-rated configuration.
No drilling a non-rated cylinder hole through a rated door. If a job needs a different prep, we order a labeled door or use a UL-approved retrofit.
Photos, listing numbers, and a one-page summary. Property managers love this for their annual life-safety binders.
A labeled fire door (look for the silver UL or Intertek label on the door edge or hinge side) is part of your building's fire-rated assembly. The door, frame, hinges, and lock must all carry matching UL listings. Standard residential locks - even good ones - are NOT acceptable on labeled fire doors. The applicable standards:
NFPA 80 - Standard for Fire Doors and Other Opening Protectives. Governs installation, maintenance, and labeling. Mandates that hardware installed on a labeled fire door must be UL-listed for fire-door use. Annual inspection required for most commercial buildings.
UL 10C - Positive Pressure Fire Tests of Door Assemblies. The certification test that locks and other hardware pass to be rated for fire-door use. Locks with UL 10C compliance get a fire-rating label on the lock body or in the spec sheet.
IFC (International Fire Code) - Florida 7th Edition. Adopted into Florida Fire Prevention Code. Specifies fire-door requirements for occupancy types - hotels (R-1), schools (E), hospitals (I-2), multi-tenant residential (R-2).
Installing a non-fire-rated lock on a labeled fire door does two bad things: (1) it voids the door's fire rating, (2) it can result in code violations on your next fire-marshal inspection that can require closing the door / room until corrected. This is not theoretical - we get called every year by PSL hotel and school facility managers who had a handyman swap a corridor lock with a hardware-store deadbolt and now they're failing inspection.
Hotels and motels along US-1. Every guest-room door is a fire door. Locks are typically Schlage L-Series mortise (UL 10C listed), Sargent 8200 series mortise, or electronic systems like Onity, Saflok, or Salto with fire-rated mortise bodies. When a hotel changes electronic key systems, the lock-body swap has to maintain UL 10C compliance. $420-720 per door depending on whether it's manual or electronic.
St Lucie County schools and PSL private schools. Classroom doors require classroom locks (lockable from outside, free egress from inside via single motion). Schlage ND80 / L-Series classroom function, Sargent 8200 classroom function. Plus barricade-resistant features post-2019 Florida school safety legislation. $380-580 per classroom door.
Multi-tenant apartment buildings. Corridor entry doors to individual units are fire doors. Lock installation has to maintain the fire rating AND meet egress requirements (single-action exit from inside the unit). Common at the older PSL apartment complexes off Walton Road and along US-1. Schlage AL-Series, Sargent 7-Line. $320-520 per door.
Hospital corridor and patient room doors. Doctor's offices, the urgent-care centers, dental and surgical practices. Locks have to allow single-action egress, key control on the patient-room side, and code-compliant fire rating. Often integrated with access control. $480-720 per door.
Commercial back-of-house and stair tower doors. Every stair tower in a building above two stories is a fire-rated assembly. Locks have to be UL 10C listed AND allow re-entry every fourth floor (or to the floor of discharge per IBC 1010). $380-580 per door.

Call (772) 284-5142UL 10C testing. The lock body and trim are tested in a fire-door assembly under standardized fire and pressure conditions. Locks that pass are listed by Underwriters Laboratories with a fire-door rating (20, 45, 60, or 90 minutes). The listing is published in the UL Online Certifications Directory and the lock body is stamped or labeled.
No - not on a labeled fire door. NFPA 80 prohibits installing non-UL-listed hardware on labeled fire doors because it voids the door's fire rating. The door, frame, hinges, and lock all have to carry matching UL listings. If your door is labeled (silver UL or Intertek label visible on the door edge), only fire-rated hardware is compliant.
Look at the door's edge on the hinge side - a labeled fire door has a silver UL or Intertek label permanently affixed there, showing the manufacturer, fire rating in minutes (20, 45, 60, 90), and certification body. The label must not be painted over, removed, or damaged. If you can't find a label, the door is either non-fire-rated OR the label has been damaged - we can verify either way during a site walk.
NFPA 80 is the Standard for Fire Doors and Other Opening Protectives - the national standard adopted into Florida Fire Prevention Code. It governs installation, maintenance, inspection, and labeling of fire-rated doors and hardware. Florida commercial occupancies (hotels, schools, hospitals, multi-tenant residential) are required to comply, and most require annual fire-door inspections that check hardware UL compliance.
$320-720 per door depending on grade, function, and complexity. Standard UL-listed mortise on a corridor door: $420-580. Classroom function on school doors: $380-580. Electronic hotel locks: $520-720. Hospital / access-control integrated: $480-720. Pricing includes UL-listed hardware (no aftermarket substitutes), labor, and NFPA 80 compliance documentation.
Yes. We do pre-inspection door surveys for PSL commercial properties - we walk every fire door in the building, verify labels are intact, check hardware UL compliance, identify non-compliant installs, and quote remediation. The pre-inspection survey is $280-480 for typical buildings. Most facility managers schedule us 30-60 days before their annual inspection.
Fire-door work in PSL covers the US-1 hotel and motel corridor, St Lucie County School District buildings (PSL High, Treasure Coast High, Centennial, plus the elementary and middle schools), multi-tenant apartment complexes off Walton Road and along US-1, the medical office park around Tradition Health, and commercial / industrial in the PSL Industrial Park off Range Line Rd.
