Common problems we fix

- Door does not stay open when it should, or will not close at all
- Closer arm is loose, bent or noisy
- Door is hard to open, with closing force that is too strong
How this works
A hydraulic closer uses a spring to close the door and a sealed fluid chamber with adjustable valves to control speed. Typical adjustments are sweep speed, which controls the main closing arc, latch speed, which controls the last few degrees, and on some models backcheck, which slows the door near full open. Spring power may also be adjustable.
Closers are sensitive to temperature because hydraulic fluid thins in heat. In Las Vegas summers a closer tuned in cool weather can slam, and the reverse can happen in a cold morning. Adjustment is often a quick fix. Fluid leaking from the body is different: that normally means seals have failed and replacement is the dependable repair.
Accessibility guidance commonly references closing time and opening force for doors in public areas. Your building owner or code official has the final say on requirements for your opening, and we can adjust to the targets they specify.
Common door and hardware configurations
- Surface-mounted hydraulic closers on the door or frame, with regular, parallel or top-jamb arms
- Overhead concealed closers in the door header or frame
- Floor closers set into the floor below a pivot
- Closers with hold-open arms, delayed action or heavy-duty spring sizes
Repair or replace?
Adjust first. If the closer is leaking, has a broken arm or no longer holds adjustment, replacement is usually the right call, since a failed hydraulic seal cannot be dependably repaired in the field.
When replacing, the closer needs to be sized for the door width, weight and exposure, and mounted correctly. A closer that is too weak for a heavy exterior door will keep failing, no matter how it is adjusted.

Frequently asked questions
Why is my commercial door closer leaking oil?
Leaking fluid usually means the internal seals have failed. A leaking closer loses control over time, so replacement is normally the practical fix.
Why does my door slam shut?
Often the latch or sweep speed is set too fast, or heat has thinned the fluid, or wind is pushing the door. Adjustment can fix the first two. A weak or leaking closer may need to be replaced.
What is the difference between an overhead concealed and a surface-mounted closer?
A surface-mounted closer is visible on the door or frame. An overhead concealed closer sits inside the door header or frame for a cleaner look. The right choice depends on the door, frame and appearance requirements.
