Commercial door replacement is more than swapping a slab. The job covers the door, the frame, the hinges, and the hardware that make one working opening. Our team measures the rough opening, checks the frame for rust or bends, and confirms the fire label and swing. We install hollow metal, wood, or aluminum storefront doors built to the right standard, such as ANSI/SDI A250.8 for steel. Each opening is set plumb and true. The result is a door that closes, latches, and locks every day.
A new door ends the cycle of service calls for sagging, rubbing, or failing old openings.
New openings meet NFPA 80 and ADA clear width rules, so your next inspection goes smoothly.
Reinforced steel doors and solid frames resist forced entry far better than worn or damaged ones.
King Locksmith And Doors Inc. is a locksmith and door company serving Maryland, Washington DC, and Northern Virginia. We replace and install commercial doors for small businesses, government agencies, hospitals, hotels, schools, and property managers. Our technicians handle the whole opening, from the frame and door to the hinges, locks, closers, and exit devices. You get one crew and one clean finish. We can also work after hours, so your doors stay open for business.
The right replacement door depends on where it sits, who uses it, and which codes apply. Use this short guide to compare door materials, fire ratings, access needs, security levels, and the full install plan.
Hollow metal doors are the workhorse of commercial buildings. They handle heavy traffic, resist dents, and work in fire-rated openings. Wood doors suit offices, hotels, and lobbies where looks matter. Aluminum storefront doors fit glass entries and retail fronts.
Think about traffic, weather, and impact. An exterior back door needs galvanized steel. A busy hallway needs a heavy-gauge door. A quiet office can use a solid-core wood door. We help you weigh cost and lifespan.
Fire doors protect stairwells, corridors, and exits. Each one carries a rating, such as 20, 45, 60, 90, or 180 minutes. The door, frame, and hardware must all carry labels that match the opening.
NFPA 80 limits what can be changed in the field. Cutting or drilling a fire door can void its label. A labeled replacement keeps your building ready for its annual fire door inspection. We check every label before and after install.
Doors on accessible routes need at least 32 inches of clear width with the door open to 90 degrees. Most standard 36-inch commercial doors meet this rule. Thresholds should stay at or below half an inch.
Interior doors that are not fire-rated should open with no more than 5 pounds of force. Lever handles, tuned closers, and smooth surfaces help guests, staff, and patients move with ease. We measure each opening to meet these rules.
Exterior and high-risk doors need more strength. Look for heavy-gauge steel, reinforced hinge and lock areas, and a frame anchored firmly to the wall. Weak frames are often the first point a burglar will attack.
Plan the hardware with the door. Mortise locks, exit devices, and access control all need the right prep. We order doors pre-machined, so every lock and strike fits cleanly the first time, with no rushed field cuts or weak spots.
Downtime costs you money. We confirm the size, swing, handing, and hardware before the door ships. That way, the old door comes out and the new one goes in during one short, planned visit.
For busy sites, our crew can work early mornings, nights, or weekends. Hospitals, hotels, and agencies keep running while we work. Before we leave, we test the latch, closer speed, and lock function, then haul the old door away for you.
Patching an old door can work for a while. But worn frames, rusted bottoms, and bent edges keep coming back. Here is how a full replacement compares with ongoing repairs.
