Fix Slamming, Latching, and Resistance Issues
A door closer is a precision hydraulic instrument. When it goes out of tune, it creates problems. If it's too loose, the door slams (breaking glass or hurting fingers). If it's too tight, customers or residents struggle to open it (creating an accessibility barrier). Installix offers expert door closer adjustment services. We don't just turn screws randomly; we scientifically tune the hydraulic valves to match the weight of your door and the air pressure of your building.
Symptoms of Poor Adjustment
The "SLAM"
The door swings freely and bangs into the frame. This loosens the frame anchors, cracks drywall, and can shatter the glass lite in the door.
Failure to Latch
The door gently closes but stops 1 inch short of the latch. This leaves your building unsecured. This is often an issue with "stack pressure" (air resistance) in high-rise buildings.
Too Heavy to Open
AODA regulations require doors to open with minimal force (typically 5lbs or 8lbs depending on location). If an elderly person cannot open your door, you are liable.
The Solution: 3-Stage Valve Tuning
Modern commercial closers have distinct hydraulic circuits. We adjust them in sequence:
- 1. Backcheck (BC): Cushions the opening swing to prevent the door from hitting the wall.
- 2. Sweep Speed (S): Controls the main closing swing (from 90 degrees down to 10 degrees).
- 3. Latch Speed (L): Provides a final "snap" action in the last few inches to overcome the latch and weatherstripping resistance.
Technical Considerations
| Factor | Adjustment |
|---|---|
| Seasonal Change | Oil viscosity changes with temperature. Closers often need adjustment in Winter (stiff) vs. Summer (loose). |
| Air Pressure | HVAC systems create positive pressure. We increase the latch speed to "power through" the air cushion. |
| Spring Tension | We adjust the spring power nut to ensure the door meets ADA/AODA opening force requirements. |
Our Process: Diagnosis & Tune
Step 1: Inspection
We check for oil leaks. If a closer is leaking oil, it cannot be adjusted; the hydraulic seal is blown and it must be replaced.
Step 2: Adjustment
Using hex keys, we tweak the valves in small increments. We test the door 10+ times to ensure consistency.
Step 3: Hardware Check
Often, a "bad closer" is actually a loose hinge or a misaligned strike plate. We tighten all mounting screws as part of the service.
Pricing Factors
- Service Call: Adjustment is primarily a labor charge (minimum service call fee).
- Quantity: It is cost-effective to have us adjust all doors in your facility during one visit.
- Replacement: If adjustment fails (leaking), the cost shifts to a closer replacement.

We make doors work the way they were designed to.
