Have you noticed a door on the backside of your building that’s rusting at the hinges or around the frame? Tired of having to use the “perfect touch” to get a door to self-lock? How about that frame that drips every time it rains? If your commercial doors and frames are showing their age or wearing out prematurely, they are likely providing inadequate security. Often, a damaged or poorly made door no longer shuts and locks properly, which presents an opportunity for intruders looking for a weak point in your building or facility security.

Protect your business by having your commercial doors and commercial steel door frames replaced or repaired by the professionals at Assured Security. We offer convenient commercial door installation and repair services for businesses and commercial buildings throughout the Minneapolis and Saint Paul metro area. Call or email us to get started! Our team of commercial door security professionals look forward to assisting you.

Our security specialists can repair or replace many types of commercial doors, including:

  • Security doors
  • Warehouse doors
  • Emergency exit doors
  • Storefront doors
  • Fire-rated doors
  • Double doors
  • Retrofit doors

Commercial doors have come a long way in recent years, so if your doors are very outdated, upgrading all entrances to secure, insulated galvanized hollow metal doors, accompanied by galvanized hollow metal door frames, is highly recommended. We won’t replace your doors unless it is required; sometimes a repair, such as new hinges, a continuous hinge, or weather-stripping, is a better option than a full replacement. Our experienced security specialists are happy to help you make an informed decision.

If your building does require commercial door replacement services, we will take care of the process from start to finish, and even key the new lock to your existing key! Contact us today to request a quote!


Entry doors are one of the most important features of your business or commercial building; they should be aesthetically pleasing and inviting to your customers and clients while offering excellent security and energy efficiency. Steel provides the ideal solution.

Superior Durability

When it comes to strength and durability, you can’t beat a hollow metal door – especially steel. The steel doors we supply will never crack, warp, or rot, and are built to withstand Minnesota’s harshest weather conditions.

And contrary to how it sounds, hollow steel doors can be safer than solid. This is because hollow steel absorbs and disperses impacts better than solid steel. So, if someone tries to bust down the frame, they are going to have a very difficult time because hollow metal doesn’t transfer the damage to the edges like solid steel sometimes can.

Energy Efficient

If your entry doors are old or poorly made, it’s possible you could be losing money every month in utility bills. This is especially true for older doors that include windows made from a single pane of glass, which are not very effective at keeping out the elements. If this is the case for your business, we recommend having modern steel doors installed. They can provide better insulation, and, therefore, improved energy efficiency and lower heating/cooling costs.

Low Maintenance

When you invest in new doors, you want them to last – and without putting in a ton of effort. Steel doors provide long-lasting durability while requiring minimal maintenance. They are designed to accommodate high traffic, so you’ll save time and money by not having to repaint, stain, or repair your door every year.

Sleek Design

Curb appeal is important for any business. If your storefront doors look old and worn out, that can create a negative first impression for a potential customer (or a positive first impression for a thief). Steel doors are not only extremely durable, energy-efficient, and low maintenance; they offer a sleek, clean look that never goes out of style. They’re also quite flexible in terms of customization.

Assured Security supplies and installs steel commercial doors with or without glass inlays.


Notice a space between your commercial door and its frame? That little gap could be a big issue for your building’s energy efficiency and security. It’s possible we can repair this with high-quality weather-stripping: however, that depends on the size of the gaps. If the gaps are too large, we may recommend investing in a new door.

Our team also provides repair services for doors that are not functioning properly due to drooping, bent or broken hinges, hardware that won’t latch, damaged thresholds and more. Contact us for more details.

  • Locks
  • Door closers
