Learn MoreDoor Closer Expertise
Commercial door closers are hydraulic devices that control the closing speed and force of doors. They are critical for fire safety (ensuring fire doors close and latch automatically), ADA compliance (limiting opening force and controlling closing speed), security (ensuring doors close and latch after each use), and energy efficiency (preventing doors from being left open). Every commercial door in the DMV that has a closer requires periodic adjustment and eventual replacement as the hydraulic mechanism wears out over time.
The most common failure mode for door closers is hydraulic fluid leakage. When internal seals wear out, fluid leaks from the closer body, which is visible as oily stains on the closer or door surface. A leaking closer loses its ability to control closing speed and will eventually fail completely, causing the door to slam or not close at all. Leaking closers cannot be repaired and must be replaced. Other common issues include incorrect adjustment causing doors to close too fast or too slowly, worn arm joints that allow the door to slam, and mounting screws that pull out from heavy use.
