Commercial Door Closer Repair & Installation in Chicago
Quick Key Locksmith & Security provides door closer repair and installation for commercial properties throughout Chicago and surrounding suburbs. We help businesses restore safe, smooth door function by repairing faulty closers or installing new hardware that matches the door’s use and weight.
We service aluminum storefront doors, fire-rated entryways, glass doors, and high-traffic commercial frames. Whether the door slams, leaks hydraulic fluid, or fails to latch, we identify the issue and complete the fix on-site.
What Is a Door Closer?
Our team repaired this malfunctioning door closer for a commercial property. We fixed it on-site and ensured that it had smooth functionality.
A door closer is a mechanical device that controls the speed and position of a door after it’s opened. It prevents slamming, supports fire safety compliance, and helps meet ADA requirements. Most commercial models use hydraulic pressure and adjustable valves to regulate closing action.
If a closer fails, it can create safety hazards, damage the frame, or leave the door ajar. Our team installs and repairs closers to ensure controlled, consistent operation for commercial buildings.
Repair Services for Commercial Door Closers
We repair malfunctioning door closers that show signs of:
- Hydraulic fluid leaks
- Slamming or slow-closing doors
- Hold-open arm failure
- Poor alignment or mounting issues
- Latching problems or excessive force
Our technicians inspect the mounting hardware, arm function, and adjustment settings to identify the issue and restore performance. We replace worn components, tighten loose fittings, and test the closer for proper control and alignment.
New Installation and Retrofit Options
If the existing door closer is damaged or outdated, we install a new unit matched to the door’s size and traffic level. We offer surface-mounted closers, floor-mounted closers for glass doors, and concealed overhead closers for aesthetic or security needs.
Each installation includes:
- Proper alignment with the frame and door
- Adjustment of latching and sweep speeds
- Secure mounting to prevent long-term wear
- ADA-compliant setup when required
We also retrofit doors that originally used a different closer type. We patch old holes or shim the bracket if needed to ensure a flush, secure fit.

- Doors that slam, stick, or stay open

FAQs About Door Closer Repair & Installation
How do I know if my door closer needs repair?
Signs of a malfunctioning door include slamming shut, delayed closing, leaking hydraulic fluid, or failing to latch. These issues often indicate your door closer needs adjustment, maintenance, or full replacement.
Can you replace the door closer without replacing the door?
Yes. We reuse the existing door and door frame when possible. If the mounting holes from the previous closer align, we use them; if not, we adjust or install new mounting hardware to ensure proper function and alignment.
What types of doors do you service?
We repair and install door closers on metal, wood, glass, and fire-rated doors in commercial spaces. Whether you have a storefront entry or an interior door in a high-traffic area, we provide the right closer for your needs.
Do you install ADA-compliant door closers?
Yes. We offer closer installation that meets ADA requirements by adjusting the opening force and closing speed. This helps provide secure, accessible entry for all users.
How long does a typical door closer repair take?
Most door closer repair services take under one hour. We complete the job on-site, adjusting the closing force, latching speed, and swing for smooth operation.
Do you carry closers for storm doors and screen doors?
Yes. We install and repair closers on storm doors and screen doors. These are often mounted with a jamb bracket and require proper adjustment to prevent slamming or gaps when shut.
Can you service floor-mounted and concealed closers?
Yes. We handle overhead concealed closers, floor-mounted closers, and surface-mounted models. Whether installed in the frame, the door, or the floor, we diagnose issues and complete the required repairs or replacements.
Do you provide mobile service outside of Chicago?
Yes. We offer mobile door closer repair and installation in Chicago and nearby suburbs, including Wheaton, Schaumburg, Oak Brook, and Arlington Heights. Our team arrives with the tools and replacement hardware needed to complete the job on-site.
What does it mean if my door closer is leaking fluid?
Leaking hydraulic fluid is a clear sign of internal wear. A closer that leaks cannot control the door’s closing speed or hold-open function. We recommend a replacement to restore safe and consistent operation in this case.
