Commercial Door Closer Service

The entrance to your building is the first impression people have about your business. If your door is difficult to open or hard to close, it may taint what would be a positive experience. Glass Doctor of Denton installs commercial door closers, which gives customers a helping hand when opening heavy storefront doors and ensures the commercial door's safety and everyone who walks through it.

What is a Door Closer?

A commercial door closer is a mechanism that, when attached to doors, allows customers to easily open and pass through heavy glass doors without having to close them physically. If properly installed, these door closers work like this:

  • Allows the users to initially feel some pullback as they open the storefront door, showing how heavy the door is.
  • After this initial resistance, the door will smoothly glide open.
  • As the customer passes through into the store, letting go of the door, a spring in the door closer will force the arm of the mechanism to close the door gently until it returns to the doorframe.

All of these steps allow for a customer to smoothly enter your store without having to physically close the door behind them.


Glass Doctor provides a wide variety of styles to choose from to match your business aesthetic. There are many questions to think through before deciding on what style you are wanting to install for your business. What is the aesthetic of your business? What is your budget? Is the door closer being installed on an existing door or being installed along with a new door? And how often will the door be used? All of these questions will help you to decide between the styles that Glass Doctor of Denton provides.

  • Regular Arm: The most power efficient, this is mounted on the exterior of the door.
  • Top Jam: Used most frequently for glass storefront doors.
  • Parallel Arm: Because of their difficulty to be vandalized, this type is used in schools.
  • Concealed: Fitted into the door or the doorframe, these are hidden from sight.
  • Surface-Mounted: Usually the most cost-efficient, these are fitted into the doorframe.
  • Floor-Spring: Hidden from sight, these are concealed and mounted to the floor.

Repair and Maintenance

Frequently the glass experts at Glass Doctor of Denton have to repair or replace door closers because of three key problems:

1. Improperly Installed and Adjusted Door Closer - If a door closer is incorrectly installed, it leads to the risk of misalignment. This can make it more difficult to open or close your storefront door; it could even lead to jams when attempting to get in or out of the building. Glass Doctor service professionals bring the right tools to install and maintain commercial door closers to ensure that:

  • Your door remains in good working condition.
  • The lifespan of your door closer is elongated.
  • Unexpected or abnormal movements of your door are prevented.

2. Incorrect Types of Door Closers - When you have heavy storefront doors, it requires you to have a strong door closer with equally strong springs. These springs hold the door's weight as it closes, so if the wrong type of closer is installed, it poses the safety risk of misalignment that can damage the closer or the actual door.

3. Broken Seals and Low Oil Levels - Oil leaks generally indicate a mechanical problem within the mechanism, such as a missing screw, a failed seal, or a broken O-ring. It is imperative to have a professional replace the oil in a door closer because a lack of lubrication causes doors to open or close too quickly, posing a possible injury risk. These leaks also can generate from broken seals, which expose clearance gaps and leave hardware vulnerable.
