Frequently Asked Questions
Why is my door closer leaking oil or slamming shut violently?
Internal seal failures cause hydraulic fluid leaks, leaving the unit without resistance. Our hydraulic door closer repair or replacement restores soft, controlled closing without door damage.
What is the difference between surface-mounted and concealed door closers?
A surface mounted door closer attaches visibly to the top frame and offers easy adjustments. Concealed closers hide inside the header frame for a sleek look, often chosen during door closer installation on glass doors.
Can you adjust the closing and latching speed on an existing closer?
Yes. Our technicians perform door closer speed adjustment by tuning sweep and latch valves to ensure doors close safely and click shut securely without slamming or staying open.
How long does a commercial door closer usually last?
High-traffic closers last 5 to 10 years depending on foot volume. Timely commercial door closer replacement prevents frame damage and maintains fire code compliance.
Are door closers required on fire-rated doors?
Yes. Fire-rated entry doors require self-closing hardware like a professional door closer installation to keep fire barriers closed automatically in emergency situations.
