Door Closer Repair & Installation
Downtown Doors & Security repairs and installs door closers across Brooklyn and Manhattan — the surface, concealed, and overhead devices that pull a door shut. We fix closers that slam, drift, leak oil, or no longer latch, and set the closing and latching speed so apartment, office, storefront, and fire doors close fully and securely.
A door closer controls how a door shuts: its speed, its final latch, and its back-check. When it fails, doors slam, drift open, don't latch, or leak hydraulic fluid — and on a fire door, a failed closer is a code violation.
We service surface-mounted, concealed, overhead-concealed, and floor closers on residential, commercial, and fire-rated doors, adjusting closing and latching speed or replacing the closer to match the door's weight and use.
When you need it
- The door slams shut or closes too hard
- The door drifts open or no longer closes fully
- The closer leaks oil or feels loose
- The door won't latch because it closes too slowly
- A fire or exit door's closer needs to meet code
How it works
- 1
Diagnose the closer & door
We check the closer, arm, mounting, and the door's weight and swing to find the real cause.
- 2
Adjust or replace
We tune closing, latching, and back-check speed, or fit the correct-size closer for the door and its use.
- 3
Verify close & latch
We cycle the door to confirm it closes smoothly, latches fully, and — on fire doors — self-closes to code.
How pricing works
Every door closers job is priced after a free on-site assessment — no guesswork and no surprises. We diagnose the real issue, explain your options in plain language, and give you clear pricing before any work begins.
Frequently asked
Can you just adjust my closer instead of replacing it?
Often, yes. If the closer is sound, we adjust the closing, latching, and back-check speed. If it's leaking or worn out, replacement is the reliable fix — we'll tell you which on site.
Do you install concealed and overhead closers?
Yes. We install surface, concealed, overhead-concealed, and floor closers, sized to the door's weight and use, including fire-rated closers where required.
