Running a business? Security is critical. Our commercial locksmith services help protect your business, assets, employees, and customers. From high-security lock installations to access control systems and rekeying.
Why Your Business Needs a Door Closer
A door closer is a mechanical device that automatically shuts a door after it opens. Though simple in concept, its role in building management and safety is critical. Commercial spaces are subject to high foot traffic, fire codes, and ADA compliance – making door closers not just useful, but often mandatory.
Key benefits of commercial door closers include:
Enhanced Security
Automatically closed doors reduce the risk of unauthorized access and improve building perimeter protection.
Energy Efficiency
Helps maintain interior climate control by preventing doors from staying open unnecessarily.
Controlled Foot Traffic
Maintains order and flow in busy environments, especially in retail, healthcare, and education facilities.
Fire Code Compliance
Many jurisdictions require self-closing doors in designated fire zones.
Damage Reduction
Prevents slamming doors that can damage frames, hinges, and flooring.
Accessibility and Convenience
Ensures ease of movement for employees, customers, and guests, especially when paired with automatic or low-resistance options.
For businesses, a reliable door closer isn’t a luxury – it’s an investment in your building’s safety, comfort, and compliance.
Overhead Concealed Closers
Hidden in the header of the frame, these closers are used where door aesthetics must be preserved while still delivering strong, reliable performance.
Best for: Glass storefronts, showrooms, and internal double-door systems.
Hydraulic Door Closers
Equipped with fluid-based resistance for smooth, controlled movement, these allow fine adjustments for closing speed, backcheck, and latching.
Best for: High-traffic environments that demand consistent performance.
ADA-Compliant and Delayed-Action Closers
These are designed for accessibility, giving more time for individuals to enter or exit. Delayed-action closers are especially helpful for elderly or disabled individuals.
Best for: Hospitals, schools, public buildings, and ADA-compliant facilities.
Types of Commercial Door Closers
Choosing the right door closer depends on your building layout, door size and weight, foot traffic, and compliance requirements. Locksmith United offers a range of options to suit every commercial setting.
Surface-Mounted Door Closers
These are the most commonly used and visible door closers. They are mounted to the surface of the door or frame and are known for easy installation and versatility.
Variants include:
- Regular Arm Mount
- Top Jamb Mount
- Parallel Arm Mount
Best for: Offices, schools, and small businesses.
Concealed Door Closers
Installed inside the door or frame, concealed closers are ideal where aesthetics are important. They offer a clean, minimal look without compromising functionality.
Best for: Upscale retail, hospitality spaces, and design-sensitive locations.
Floor-Spring Door Closers
Mounted beneath the door in the floor, these closers are designed to handle heavy doors and are common in storefronts with glass entries.
Best for: Glass doors, large pivot doors, and high-traffic commercial entrances.
Our Step-by-Step Door Closer Installation Process
Every installation performed by Locksmith United is handled with precision, ensuring long-term performance and full compliance with local codes. Here’s how we approach each job:
1. Site Assessment and Consultation
We begin by evaluating your existing doors, usage patterns, and compliance needs. We’ll determine the correct type and configuration of door closer based on:
- Door material and weight
- Fire safety and accessibility code requirements
- Existing hardware and structural integrity
- Expected foot traffic volume
2. Selection of Door Closer
Based on our assessment, we recommend the most suitable door closer that meets your needs and budget. We only use trusted commercial-grade brands for reliability and warranty protection.
3. Door and Frame Preparation
Our technicians measure and mark mounting points precisely, ensuring that the installation is accurate and aligned. For concealed or floor-mounted models, structural modifications may be required.
4. Mounting and Alignment
We securely attach the closer and ensure all components – arms, brackets, valves – are properly installed and balanced. Whether surface-mounted or recessed, we ensure zero drift or misalignment.
5. Tension and Speed Adjustment
After installation, we fine-tune key performance settings:
- Closing speed – how quickly the door shuts
- Latching force – final push to close the door completely
- Backcheck – resistance to abrupt opening
- Delayed action – slow-close option for accessibility
6. Testing and Final Inspection
We conduct multiple opening and closing tests to ensure smooth motion, proper latch engagement, and compliance with fire and accessibility standards.
Once approved, we document the work and provide you with post-installation guidance and warranty information.
Compliance and Safety Standards
A commercial door closer is more than a functional upgrade – it’s often a legal requirement. Our installations comply with:
- NFPA fire door standards
- ADA accessibility guidelines
- Local fire and building codes
- OSHA regulations for commercial facilities
- Manufacturer-specific warranty and performance guidelines
We also install closers on fire-rated doors with UL-listed hardware to ensure full legal compliance. If you’re unsure whether your doors meet current code, we offer a compliance inspection and report service.
Brands and Hardware Compatibility
We install and service commercial-grade door closers from industry-leading manufacturers, ensuring compatibility with various door materials, control systems, and architectural styles.
Brands We Work With:
- LCN
- Norton
- Dorma
- Yale
- Sargent
- Hager
- Falcon
- Jackson
- Corbin Russwin
- ASSA ABLOY
Whether you’re replacing an old closer or upgrading to a more advanced system, we ensure full compatibility with your existing infrastructure.
