Frequently Asked Questions About Door Closers
Why is my door closer leaking oil?
A closer that is leaking oil has a damaged or broken seal, which affects its hydraulic system. This can cause the door to slam shut or fail to close properly. If you notice oil leaks, it’s important to get it repaired or replaced immediately to prevent further damage.
How can I tell if my door closer needs repair or replacement?
Signs that your closer may need attention include:
The door slams shut instead of closing smoothly.
The door does not latch properly after closing.
Unusual noises, such as creaking or grinding.
Resistance when opening the door or difficulty staying open.
If you experience any of these issues, our locksmiths can assess your closer and determine if repair or replacement is needed.
Can I install a door closer on any type of door?
Yes! Our team installs closers on wood, metal, and glass doors. We’ll help you select the right type of closer to ensure proper operation and durability.

To ensure optimal performance, closers should be inspected and adjusted at least once a year. Regular maintenance prevents unexpected breakdowns, ensures compliance with fire safety regulations, and extends the lifespan of your door hardware.
