Gateway Door and Contracting services commercial and industrial garage doors throughout Earth City. Veteran owned and family run, working on doors across the St. Louis region. When a commercial door goes down, the cost is not inconvenience, it is downtime. Trucks cannot load, the bay is unusable, and every hour matters.
We diagnose properly, quote clearly, and turn up when we said. For a business that means a realistic time window rather than a vague promise.
Garage Door Replacement in Earth City
Earth City is overwhelmingly commercial, so most of our work here is sectional dock doors, rolling steel, high-speed doors and the openers and hardware that drive them. Commercial work is quoted per opening, but the 2026 pricing guide gives a useful floor for the sectional and roll-up types fitted here.
Common Garage Door Problems We Fix in Earth City, MO
Commercial doors fail in particular ways, usually through sheer cycle volume. These are the faults we are called out to most across Earth City.
What we get called to at Earth City:
- Dock doors and roll-up shutters that have run past their cycle rating
- Commercial operators failing under duty cycles a domestic unit would never survive
- Impact damage from forklifts and reversing trailers, the most common cause here
- Springs on doors wide and heavy enough to need a proper commercial assembly
- Tracks knocked out of alignment in daily loading use

Gateway Door and Contracting made my week! I had a side garage door that had been giving me trouble for some time. I had been putting off calling someone because it seems like everything turns into a hassle. Not this. The receptionist on the phone was very helpful and understanding and the man that came to repair the door was very efficient and helpful. I highly recommend this company to anyone needing help with their garage doors.

Rolling Steel Doors
Rolling steel doors where space is tight and security is the priority.

Garage Door Considerations in Earth City, MO
Earth City is one of the largest business and industrial parks in the St. Louis region, sitting in the Missouri River bottoms with a huge concentration of warehousing, distribution and light manufacturing. There is very little residential property here, so nearly everything we do in Earth City is commercial.
Commercial doors wear out on cycles rather than years. A dock door opening and closing dozens of times a day will exhaust springs and cables in a fraction of the time a residential door takes, and the loads involved make a failure genuinely dangerous. Regular servicing is far cheaper than an emergency callout and a lost shift.
For a business the calculation is simple. A correctly specified door with the right cycle rating, serviced on a schedule, costs less over its life than repeated breakdowns on an under-specified one. We will tell you honestly which category your current doors fall into.
