Our Story

It Started With a Grandfather and an Uncle

Sean Rogers started in the trade at sixteen, working alongside his grandfather and uncle in the family garage door business. He learned it the way the trade has always been learned: on the job, on real openings, with someone looking over his shoulder.

In 2015 he moved to Golden and started his own company, carrying the same standard forward. What began with residential doors across the foothills has grown into a commercial contractor handling rolling steel, high speed doors, loading dock equipment, gate operators and access control for warehouses, distribution centers and industrial sites across the Front Range.

The name changed to match the work. The standard did not.

Where We Focus

Docks and Doors, Under One Contractor

Most buildings end up with one vendor for the door, another for the dock equipment, and a third for the operator and controls. We handle all three, which is usually the difference between an opening that works and an opening that gets blamed on someone else.

Commercial Doors

Rolling steel service doors, fire rated rolling doors and counter shutters, high speed fabric and rigid doors, commercial sectional doors and security grilles.

Loading Docks

Levelers, seals, shelters, bumpers and vehicle restraints. Repaired, rebuilt or replaced without taking your shipping bays out of service for a week.

Gates & Access

Slide and swing gate operators, loop detection, keypads, card readers and intercom integration for yards, lots and secured service entrances.

Meet the Owner

A Specialist, Not a Dispatcher

Sean Rogers owns and runs the company, and he is still on job sites. That matters more than it sounds: the person quoting your work is the person who understands what the opening actually needs, not a salesperson relaying it to a crew they have never met.

The crews are ours. When you call, you get the people who will be on site, not a call center routing the job to whoever is available that day.

That is also why the diagnosis tends to come before the sales pitch. Plenty of our customers found us after another company quoted a full replacement for a problem that turned out to be one component.

How We Work

What You Get Working With Us

Early Involvement on New Builds

We take off drawings, confirm rough opening and backroom conditions before the slab goes down, and coordinate with the electrician on power and controls.

Documentation That Holds Up

Fire rated door drop testing documented for your inspection file, so it is complete when the fire marshal or your insurance carrier asks for it.

Honest Arrival Windows

On an emergency you get a realistic window based on where our crews actually are, not an optimistic one that makes the call easier.

Upfront Scope and Price

You get the number before work begins, written so you can actually get it approved. No hidden fees and no repairs you do not need.

Planned Maintenance

Scheduled service on a cycle that matches your door count and run rate. Facilities on a program replace far fewer doors on an emergency basis.

One Contractor Per Opening

Door, dock, operator and controls from the same team, so nothing falls into the gap between three vendors blaming each other.

We hired Sean and his team to instal 4 garage doors on our 10,000 sqft tube steel building. I was referred to Sean by the salesman that I purchased my building from which made me feel comfortable that he knew exactly how to install the garage doors direct to the tube steel, and he did! We installed a 12x14, and 3 - 16x8, with one of them being a vertical lift door. We are happy with the doors that we received and thrilled with the installation. Really gives off the impression that he cares about his customers and will do whats right to keep the garage doors in good working order. Very easy to work with, A+ solid company.
