Commercial Door Services We Provide


At Union Door, we can repair, install, or replace just about anything door related. We also offer reoccurring Maintenance & Inspection Agreements. Our M&I program also includes the required UL/NFPA code compliance testing for your fire-rated door equipment.


We service all brands and types of the following door systems.



Looking to install a new door, gate, or grille? Having the right system in place is important. Maybe you have an idea in mind for a rolling door but what you really need is a fire-rated steel door. Contact us for a free consultation so we can get you on the right path for your building's project.

Under a new construction project? We can work with your construction crew to install a system that is the perfect solution to last for years.

Check out our door system solutions we can install for your commercial uses.


Is your door, gate, or grille acting up? Since commercial doors are often overworked without a maintenance plan, they end up breaking, slowing down, or pieces of the system bust. If pieces have fallen off, broken down, or your building door doesn't perform the same as it used to, give us a call and we'll come check it out to get it fixed.

We have a team of highly-trained, licensed, and insured technicians. Many local businesses contact us after they reached out to other commercial door companies just to find out that they can't help because they don't have enough experience. Our team has plenty of experience and we'll be fully transparent with you if we can't fix the situation.

We repair rolling doors, gates, automatic doors, and are up for any other challenge. Call us today if you need your commercial door fixed.


We offer businesses a Maintenance & Inspection Agreement program to keep your installed/repaired doors functional. Setting up this automated system allows you to not stress about when the next time is that you'll need to check on your door's performance. Keeping a maintenance plan for these powerful door systems keeps repair costs down and increases the longevity of the system.

Give us a call if you're interested in setting up a M&I plan with us.
