Keeping the property doors at your business operating as they should is a must. Fortunately, commercial door maintenance is relatively straightforward and a professional can complete the task quickly.

1. Hinge Lubrication

Hinges are a key component when it comes to a properly operating door that doesn't stick or make unwelcome noises. During maintenance, each hinge is carefully inspected for damages and to ensure the hinge pins are properly seated within the hinges. Any necessary repairs are made and then the hinges are thoroughly cleaned to remove any grime that could impede movement. Finally, lubricant is added to each hinge to make sure it moves smoothly and doesn't squeak. 

2. Lock & Latch Tuneup

Locks and door latching systems vary by door. Some doors have fixed handles with detached latches, while others have handles or knobs that are turned to engage the latch. Locking systems can range from the standard keyed deadbolt to electronic keyless entry systems. Maintenance begins with cleaning out all mechanical parts of the lock and latch system, then moving parts are lubricated to ensure proper operation. 

3. Panel Inspection

Depending on the type of door, there may be glass panels that require some maintenance. Your technician will inspect the glazing that holds the glass in place and seal it against moisture. If the glazing is peeling, crumbling, or otherwise in disrepair, then it may need to be scraped off so the panels can be reglazed. Then they will clean the glass and buff out any small surface scratches that are present.

4. Door Closer Testing

Often a commercial door must be equipped with a pneumatic door closer, which is the arm at the top that pulls the door closed after each use. These are often a requirement under fire codes to ensure in an emergency the door closes and slows the spread of fire and smoke in the building. The technician will test the closer to make sure it is still functioning as needed. If not, they may need to replace the pneumatic arm.

5. Weatherstripping Repairs

Weatherstripping typically runs the length of each side of the door and along the top. On the bottom of the door should be a threshold sweep, which is a larger rubber flange that acts both as weatherstripping to keep out moisture and as a sweep to keep debris from interfering with the door's operation. Over time, these weatherstripping components can wear out and require replacement.
