Doors That Slam Shut
When the closing or latching speed is set too fast, or the closer has lost control of the door, it slams. We adjust the closer so the door comes to a controlled, quiet close.
Commercial Door Closer Repair in Washington, DC
Door closer repair in Washington, DC usually starts when something changes: the door slams hard enough to rattle the frame, drifts shut so slowly it never latches, or leaves an oily streak down the door. On a busy entrance, those problems affect security, comfort and the wear on the rest of your door hardware.
Northwest DC Locksmith adjusts, repairs, replaces and installs door closers for offices, storefronts, restaurants and apartment buildings across Washington, DC. Call 202-798-0160 or book a visit to have your door checked.
Door Closer Problems We Fix
If one of these sounds familiar, the closer is the first thing we check:
Doors Closing Too Slowly
A door that takes too long to close lets heated or cooled air out and may be left open behind people. Adjustment usually fixes it, unless the closer itself is failing.
Doors Not Closing Fully
If the door stops short of the frame, we check closer power, arm position, hinges and the latch so the door closes and latches on its own.
Leaking Hydraulic Closers
Oil on the closer body, the door or the floor means the internal seals have failed. A leaking hydraulic closer can't be adjusted back into shape and usually needs replacing.
Arm and Alignment Problems
Loose, bent or incorrectly mounted arms, and doors that have sagged on their hinges, throw off how a closer works. We re-secure or replace arms and correct alignment where possible.
New Closer Installation
We install surface-mounted closers on new doors, replace worn-out units, and choose closers suited to heavy commercial doors and high-traffic entrances.
How Door Closer Repair Works
1. Watch the door in action. We open and close the door several times to see how it moves, then look for oil leaks, loose arms, worn hinges and latch problems.
2. Adjust when we can. Most closers have separate controls for closing speed and latching speed, and many also have backcheck to slow the door when it’s pushed open hard. If the closer is in good condition, careful adjustment often solves the problem.
3. Repair or replace when needed. Leaking closers, stripped mounting holes or units too light for the door are replaced with a properly sized closer. You’ll get a price before any work begins.
4. Test the finished door. We make sure the door closes at a controlled speed and latches fully. If the latch, lock or panic bar is part of the problem, we can take care of that on the same visit.
Door Closers We Install and Service
We work on commercial surface-mounted closers, including LCN and Norton models, in the most common mounting styles:
- Regular arm closers: mounted on the pull side of the door with the arm extending to the frame.
- Parallel arm closers: mounted on the push side, common on storefronts and exterior doors.
- Top jamb closers: mounted on the frame where the door style or space calls for it.
- Heavy commercial doors: building entrances, stairwell and corridor doors that need a stronger closer.
Many people call these automatic door closers, since they close the door without anyone pulling it shut. Some doors, such as fire-rated or accessible entrances, have specific requirements for how they close. If you have questions about what your building requires, the DC Department of Buildings or your fire marshal is the right authority.

Frequently Asked Questions
Can a leaking door closer be repaired?
In most cases, no. When a hydraulic closer leaks oil, its internal seals have failed and it can no longer control the door reliably. Replacing it with a properly sized closer is usually the right fix.
Why is my door slamming shut?
Usually the closing or latching speed is set too fast, or the closer has lost fluid and can't control the door. If the closer isn't leaking, an adjustment often solves it.
Why won't my door close all the way?
Common causes include a closer that's too weak for the door, an arm that needs adjusting, a sagging door, worn hinges or a latch dragging on the strike. We check each of these before recommending repair or replacement.
Do you install new door closers?
Yes. We install surface-mounted closers on new and existing commercial doors, including LCN and Norton models, and choose a closer suited to the door's size, weight and traffic.
How much does door closer repair cost in Washington, DC?
Cost depends on whether the closer needs an adjustment or a replacement, and on the type of door and closer. We inspect the door and give you a price before work begins.
Do you service door closers in apartment buildings?
Yes. We work on entrance, lobby, corridor and stairwell doors in apartment and condo buildings, and can check several doors in one visit.
