    Our Door Closer Repair and Adjustment Process

    1. Inspection and Diagnosis

    We begin by inspecting the closer’s mounting, seals, and internal components to identify wear, leaks, or calibration issues.

    2. Cleaning and Lubrication

    Dirt and debris can restrict motion. We clean and re-lubricate moving parts to ensure smoother function.

    3. Hydraulic or Mechanical Adjustments

    We fine-tune sweep speed, latch tension, and backcheck for smooth, safe door operation.

    4. Component Replacement

    When necessary, we replace damaged arms, seals, or valves with manufacturer-approved parts.

    5. System Testing

    We verify consistent performance, ADA push force compliance, and safe closure across all door types.

    If your hardware includes an automatic mechanism, our technicians also test power, sensors, and delay timers.

    Hydraulic vs. Automatic Door Closers — What We Service

    Hydraulic Door Closers

    Hydraulic door closers are frequently utilized in various settings such as offices, educational institutions, and retail establishments. These essential units employ internal fluid pressure to effectively manage the motion of doors, ensuring they close smoothly and securely. Our repair services cover a range of common issues, including:

    • Leaking seals that can compromise performance
    • Damaged pistons that hinder functionality
    • Imbalanced closing speeds that disrupt usability
    • Mounting and alignment issues that affect door operation

    We are here to help!

    Automatic Door Closers

    Automatic door closers are perfect for ensuring ADA accessibility and are particularly beneficial in high-traffic environments where efficiency is key. Our comprehensive services include:

    • Troubleshooting power supply and sensor issues to ensure smooth operation
    • Addressing wiring and actuator malfunctions for reliable functionality
    • Adjusting incorrect timing or delay settings for optimal performance
    • Facilitating seamless integration with access control systems to enhance security and convenience

    When to Repair vs. Replace a Door Closer

    Deciding whether to repair or replace a door closer is important for keeping your doors safe and functional. Often, repairing is the best choice. This is especially true if the closer body and arms are in good shape. However, there are times when replacement is necessary.

    You should think about replacing the closer if you see hydraulic fluid leaking. This can mean there is a serious problem. If the closer body is cracked or bent, it may not work well anymore, so you will need a new one. Another sign for replacement is when automatic doors keep failing. This could be due to damage to the motor or control board. Finally, if your hardware does not meet ADA or safety codes, you must replace it to ensure safety and access.

    If you think replacement is the best option, please check our Commercial Door Closer Installation service page. This page is for Greenbelt, MD. You can learn more about our professional services there.
