Your heavy duty door sags and no longer latches?, so its blast rating protects nothing. King Locksmith And Doors Inc. rehangs, repairs and installs heavy duty doors with genuine Grade 1 hardware, 25 years DMV-wide, Licensed, Bonded & Insured, upfront quotes, free estimates. Call now.
Most heavy duty doors fail at the hinges first. A 400-pound blast resistant leaf on worn ball-bearing hinges drops at the strike side, the closer strains to pull it home, and the latch bolt rides the strike instead of entering it. DMV humidity adds corrosion along a scratched galvannealed bottom rail, and gaskets on gas tight doors slowly lose compression.
Our call is simple. If the leaf and welded frame are square, we repair: continuous hinges, a heavier closer, a new multipoint lock, fresh seals. If the core is delaminated, the frame rusted through, an impact deformed the leaf, or the rating label is gone, King Locksmith And Doors Inc. replaces it; a compromised rated door cannot be recertified onsite.
Your heavy duty door is dragging, sticking or refusing to latch, and every hour it stays that way your rating means nothing. King Locksmiths fixes it today.
Rated doors live or die on details. Our technicians match UL 752 ballistic levels to the threat, confirm ASTM F3038 forced entry ratings, and anchor blast doors into structure, not drywall, because a Level 8 leaf in a weak frame protects nobody. We specify heavy gauge or corrosion resistant steel for exposed openings as a Leading Door Hardware Brands Supplier.
A heavy duty door that will not secure is an emergency for a data room, pharmacy or loading dock. Our technicians reach most of Maryland, Washington DC and Northern Virginia in 20 to 50 minutes with hinges, closers, locks and seals already aboard. Licensed, Bonded & Insured, ALOA and SAVTA members, we handle rated openings the way facilities managers expect.
We measure the opening, check plumb and square, test hinge play, closer speed and latch engagement, then quote in writing.
King Locksmith And Doors Inc. recommends repair or replacement against clear criteria and lays out rating, material and hardware options.
Our technicians rebuild hinges and locks on site or set the new leaf and welded frame, anchored into solid structure.
We cycle the door, verify latch and seal compression, confirm the rating label is intact, then walk you through operation.

Blast doors resist explosion pressure waves and are tested to ASTM F2247; bulletproof doors stop projectiles under UL 752. Many facilities need both; King Locksmiths specifies accordingly.
Yes, if the leaf, frame and rating label are intact. We fit continuous hinges, heavier closers and new locks without affecting the rating. Call for an assessment.
UL 752 Level 3 covers handguns; Levels 4 to 8 cover rifles. Storefronts and lobbies usually need Level 3, government facilities often higher. We help you decide.
High cycle doors use ball-bearing or continuous hinges, heavy duty closers and Grade 1 hardware rated for hundreds of daily operations, so warehouses stop replacing hinges yearly.
