Our Door Closer Repair and Adjustment Process

1. Inspection and Diagnosis

We start by inspecting the door closer’s mounting points, seals, and internal components to identify wear, leaks, misalignment, or adjustment problems.

2. Cleaning and Lubrication

Dirt, dust, and debris can affect how the closer performs. We clean and lubricate the necessary moving parts to help restore smoother operation.

3. Hydraulic or Mechanical Adjustments

We adjust sweep speed, latch speed, backcheck, and closing tension to improve safety, control, and overall door performance.

4. Component Replacement

When needed, we replace worn or damaged parts such as arms, seals, brackets, or valves using compatible commercial-grade hardware.

5. System Testing

After service is complete, we test the closer to confirm smooth operation, proper closing action, and consistent performance across the full door cycle.

If your system includes automatic door hardware, we also inspect related components such as power connections, sensors, and timing settings to help ensure reliable operation.

Hydraulic vs. Automatic Door Closers — What We Service

Hydraulic Door Closers

Hydraulic door closers are commonly used in offices, schools, retail stores, and other commercial buildings. These systems use internal fluid pressure to control how a door closes, helping it shut safely and consistently. Our door closer repair services address common issues such as:

  • Leaking seals that reduce closing performance
  • Damaged pistons or internal components
  • Uneven or imbalanced closing speeds
  • Mounting, bracket, or alignment problems

Our team works to restore smooth door movement and dependable closing action for busy commercial entry points.

Automatic Door Closers

Automatic door closers help support ADA accessibility and are especially useful in high-traffic commercial environments. These systems require proper adjustment and maintenance to stay safe and dependable. Our service includes:

  • Troubleshooting power supply and sensor issues
  • Diagnosing wiring and actuator problems
  • Adjusting timing and delay settings
  • Supporting integration with access control systems

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.
