How to maintain your Commercial Doors for your Building!

A commercial door is an important part of your business, so it should be able to withstand a great deal of wear and abuse. For the security and safety of your business, staff, and customers, you want to make sure that all of the doors in your commercial space are working properly. One way to ensure this is by performing routine maintenance and inspection of your commercial doors.

Doors used in commercial applications consist of various parts and hardware that need individual attention during maintenance. Our commercial door Washington DC specialists recommend implementing the following checks to your typical spring-cleaning routine.

Commercial Door Parts Maintenance

Door Closers

Look for any greasy residue at the bottom of the closer and on the floor directly beneath it. This is an indicator of leakage that needs to be tackled in order to avoid damage to the components in the door locking mechanism or the door frame itself.

Exit Devices with Alarms

Check the exit devices and any leaking or corrosion in their batteries. Although you can use generic batteries for your exit devices, commercial door locksmith professionals advise using name brands as they have a longer lifespan.

Weather Stripping

Check if the weatherstripping has ripped or is worn out. If you feel a draft even when the door is closed, it is time to replace the weather stripping. Replace cracked seals around your commercial doors as soon as possible to keep your doors in good working order and your space’s interior insulated.

Strike Alignment and Lock Latching

Keep the area around the door clear and make sure nothing is obstructing the door perimeter. Check that your locking hardware’s latch and strike are a tight fit. You may need to tighten the door’s seal to reduce drafts and save on energy expenditures.


Over time, the door threshold will start to slack. When you hear a whistling noise at your door, you need to adjust the threshold (use a head screwdriver and utility knife)  to prevent the air from moving through the door.


Regularly lubricate the hinges to minimize damage caused by frequent metal-on-metal contact and prevent rust. If you feel tension on the locking hardware or the door is rubbing against the frame, it is likely that a hinge has loosened and needs to be tightened. Check the door for busted or bent hinges and replace them.

Latch Pockets on Concealed Vertical Rods

If your door has concealed vertical rods, sweep or vacuum debris from and out of the threshold latch pocket. Clean latch pockets allow the bottom rod to extend fully and secure the door properly.

Benefits of regular commercial door maintenance

Taking the effort to look after your commercial doors while they are still in good working order will help you avoid major problems that could end up costing you a lot of money in the long run. Regular maintenance also ensures that your doors are in excellent working order and improves the safety of your commercial space. A broken door is not only a hassle but could also cost you a lot of money if you have to close or slow down your business to get the door repaired. Regular maintenance prevents downtime in your business operation.
