Is Your Fire Rated Door Worth Repairing?

Most fire door failures are quiet. A tired closer stalls the door short of the strike. A wedge under a stairwell door pulls the hinges out of line. A new lock leaves an open hole in a hollow metal door. Across the DMV’s older buildings, we find these on almost every fire door inspection, and none survive a fire.

King Locksmith And Doors Inc. repairs when the assembly can still meet NFPA 80: a legible label, clearances within tolerance, holes small enough for listed steel fillers, and a closer or latch we can replace with listed hardware. We recommend a new fire rated door assembly when the label is gone, the door is warped past the clearance limit, or the frame anchors have let go.

Why Choose King Locksmiths for Fire Rated Doors Installation

Fire door work is where a locksmith earns trust, because listing rules govern every screw. Alongside lock installation, rekeying and access control, we keep rated openings compliant.

Every Part We Fit Carries a Listing

A fire door is only as rated as its weakest component. Our technicians fit closers, ball-bearing hinges, latches, fire exit hardware and smoke gasketing listed for positive-pressure (UL 10C) fire door assemblies, stocked as a Leading Door Hardware Brands Supplier.

We match Von Duprin, LCN, Hager and Steelcraft parts to the label on the door, and never field-modify an opening beyond what its listing allows.

Upfront Repair Quotes, Free Installation Estimates

Our fire door repair quotes arrive in writing before we touch the door: the deficiency, the listed part that corrects it, the labor, no hidden fees.

Full fire rated door and frame installation gets a free on-site estimate that specifies the rating, frame type, hardware set and anchoring. If a repair will not pass inspection, we say so and price replacement.

25 Years of Rated Openings, 20 to 50 Minutes Away

25 years of commercial fire doors across Maryland, Washington DC and Northern Virginia taught us this building stock: 1960s hollow metal frames grouted into block, rowhouses converted to apartments with 20-minute unit doors, federal facilities with 90-minute double stairwell doors.

FAQ

Fire door questions we hear most, answered by King Locksmith And Doors Inc. technicians.

(240) 345-1455

What fire rating does my door need?

The wall sets it: 20-minute for corridor and unit doors, 45 or 60-minute for one-hour walls, 90-minute for stairwells. King Locksmith And Doors Inc. confirms on site.

Paint the door, never the label or intumescent seals. A painted label fails inspection until uncovered and verified, or the door is relabeled. We arrange both.

Where panic hardware is required, a fire door takes fire exit hardware, never a standard bar with mechanical dogging. King Locksmith And Doors Inc. fits the listed device.

NFPA 80 requires an annual fire door inspection, documented and kept for the authority having jurisdiction. King Locksmiths inspects, documents and corrects deficiencies in one visit. Schedule yours.

We swap slabs into existing labeled frames without demolition and set new welded frames after hours so corridors stay open. Request a replacement estimate from King Locksmiths.
