Commercial Garage Doors

Our Business is Commercial Doors!

Reliable Door & Supply has been serving commercial clients in the Grand Forks area since 2012. In a short amount of time, we’ve proven ourselves to hold an impressive degree of knowledge, and our technicians display an unparalleled level of skill amongst our peers. We’re not resting on our laurels, though; our goal is to improve daily in all areas of our business.   

The Right Product at the Right Price. The Right Way to do Business.

We carry commercial garage doors from the best manufacturers in the industry, and we’re always on the lookout for better products to add to our line. The businesses we service have specific requirements that must be met in their commercial garage doors. It is crucial to the day-to-day operation of their businesses, and for the security and integrity of their products, that these doors perform as stated. At Reliable Door & Supply, we will work closely with you to ensure that you get the doors that meet your needs. In the process, we won’t try to sell you features that are of no use to you, nor would we want you to settle for something that won’t hold up to the rigors of your operation.

No Job is Too Big or Too Small

R-Value refers to the insulative properties of a door and is an important consideration for anyone doing business in our northern climate. We carry doors of all sizes, including over-sized commercial doors, doors fit for extreme environments, and bulk doors suited for multiple entrances for buildings such as storage units. Our client base includes, but is in no way limited to:

  • Hospitals and Clinics
  • Schools & Universities
  • Airports
  • Storage Units
  • Food Service Industries
  • Manufacturing Facilities
  • Warehouses
  • Commercial & Industrial Complexes
  • Agricultural Buildings & Commodity Storage Facilities
  • Office Buildings
  • Government Structures


Proper installation is the key to the longevity and proper function of commercial garage doors. No matter how great a door looks, if it doesn’t work right, it might as well be just another brick in the wall. At Reliable Door & Supply, we also install the products we sell or, if you’re so inclined, you can perform the installation yourself. Our highly-trained technicians provide repair work for garage doors of any make and model, whether or not they were purchased from us.

Service Plans

An overhead door requires routine maintenance on its mechanical parts to maintain optimal performance. Issues with garage doors typically start out small and, if unnoticed or ignored, may lead to major problems, such as damaged panels or being thrown off or out of track. With preventive maintenance, your commercial overhead door, lift, and other parts will provide your business with years of dependable performance. Reliable Door & Supply will work with you to develop a service plan that meets your needs, regardless of the size of your business.
