Why should I choose professional door closer installation?

Professional installation ensures the door closer is sized correctly for the door weight and usage, mounted with proper fasteners and alignment, and adjusted for closing speed, latch action and regulatory compliance.

What types of doors can you install closers on?

We install door closers on interior and exterior doors, metal‑frame doors, wood doors, fire‑rated doors, glass storefront doors, and doors in high‑traffic commercial settings.

How do you ensure code and safety requirements are met?

We select a door closer configuration that suits the door’s function, check mounting and arm type per manufacturer template, adjust closing and latching speeds, and verify any fire door or accessibility (e.g., ADA) requirements are satisfied.

What if my existing door closer is leaking or not functioning correctly?

If a door closer is leaking hydraulic fluid, has worn fasteners, is misaligned or failing to latch properly, we can replace the unit or repair it, and then calibrate the new or serviced closer to restore safe and reliable operation.

Can you help maintain door closers after installation?

Yes. We offer inspection and maintenance services that include checking fasteners, verifying arm alignment, adjusting closing and latch speeds, and ensuring the closer continues to operate as intended over time.

What Is a Commercial Door Closer and Why It Matters

A door closer controls how a door opens and closes — ensuring that it shuts automatically after use. Proper installation helps prevent slamming, reduces wear, and keeps the door aligned with its frame.

In commercial buildings, closers are critical for:

Fire safety and smoke control
Energy efficiency and climate management
ADA accessibility compliance
Security and controlled access

A well-installed door closer also reduces maintenance costs by minimizing stress on hinges and locks.

Our Professional Installation Process

1. Door Assessment

We inspect door weight, size, and traffic patterns to determine the best closer type and mounting style.

2. Product Selection

We recommend durable, code-rated hardware from brands like Norton, LCN, Dorma, and Yale.

3. Precision Mounting and Alignment

Our technicians install the closer — surface-mounted or concealed — ensuring correct spring tension, arm position, and closing speed.

4. Calibration and Testing

We adjust sweep speed, latch action, and backcheck function to achieve safe, smooth operation.

5. Integration Check

We confirm compatibility with related door hardware, such as Commercial Push Bars, lever handles, and access control systems.

Types of Door Closers We Install

Surface-Mounted Door Closers: Most common for office and retail entrances
Concealed Door Closers: Hidden within the door or frame for clean aesthetics
Floor-Spring Closers: Used on glass and heavy doors
Automatic Door Closers: Electrically powered or ADA-activated for accessibility
Heavy-Duty Hydraulic Closers: Designed for high-traffic or industrial environments

Our installations are tailored to your door size, material, and daily use volume.

When to Replace or Upgrade a Door Closer

Door closers should be inspected regularly. Replacement or adjustment may be needed if:

Doors slam or fail to latch completely
You notice oil leakage or inconsistent closing speed
Doors don’t meet ADA push-force standards
You’re installing new push bars or lever handles
The closer arm is damaged or loose
