Gateway Door and Contracting repairs and replaces garage doors across Troy and the rest of Lincoln County, most jobs the same day. We are veteran owned and family run, with a 5.0 rating from 589 Google reviews. Troy is worth knowing a little about before you buy a door here, because the town writes its own building code and the numbers in it are not the ones used down in St. Charles County.
Troy still runs the 2015 International Residential Code, adopted by Ordinance 1223 and in force since 1 September 2016. That is a six-year-older edition than the 2021 code most of St. Charles County uses, and it is enforced here by the Building Commissioner rather than a building official or a separate department.
Garage Door Replacement in Troy
We handle residential doors across town and commercial openings for businesses along the Highway 61 corridor. Repairs are the bulk of it. If you want figures before you call, our 2026 pricing guide lists installed costs by door type.
Common Garage Door Problems We Fix in Troy, MO
Troy sits at the top of the county and takes weather that the towns further south often miss. The failures we get called to here reflect that as much as they reflect the age of the door.
What we get called out for in Troy:
- Broken torsion springs, comfortably the most common call, and the one repair nobody should attempt without the right winding bars
- Openers that run without moving the door, which is usually a stripped drive gear rather than a dead motor and usually the cheaper outcome
- Dry rollers and worn bearings, louder on the wide doors fitted to newer subdivisions than on an older single
- Doors pulled out of square after a cable lets go on one side, which on a wide door bends the track as it goes
- Frost-heaved slabs throwing the bottom seal out of contact, which matters here because Troy builds to a 30-inch frost line
- Original hardware reaching the end of its life all at once, hinges, rollers, cables and drums together, common on the older detached garages near the square

Joe replaced our 28 year old garage door opener on Monday 6/10/24. The problem was a fried circuit board for which there were no replacement parts available. We have run into this with other items in our house. Joe was very efficient and explained everything he was doing. He also programed the opener in my car. Many thanks for an excellent job done.

Popular Garage Door Styles in Troy, MO
As the county seat, Troy has a wider mix of property than most towns around here, from older homes near the square to newer subdivisions on the edges. Door choice tends to follow the age and style of the house more than anything else.
Insulated Steel Doors

Insulated steel that takes daily cycling in its stride and holds its shape through hard winters.
Best for: attached garages used as the main entrance.
Carriage House Style

Carriage house detailing that suits older homes near the center of town.
Best for: period properties and street-facing garages.
Aluminum and Glass

Aluminum and glass panels for light and a modern look.
Best for: newer builds, workshops and hobby space.
Garage Door Considerations in Troy, MO
Troy amends the code table that sets local design conditions, and three of those numbers matter for a garage. The ultimate design wind speed is 115 mph, the ground snow load is 20, and the frost line depth is 30 inches. The seismic design category is B, and separately every build in town has to meet the state earthquake provisions at RSMo 319.200 to 319.207.
Wind is the one people underestimate. A garage door is the biggest single opening in a house, and when one fails in a storm the pressure that follows can take the roof structure with it. Doors carry a wind load rating, most builder-grade doors carry a low one, and it is a fair question to ask before you sign.
For a like-for-like replacement in an existing opening none of this needs a permit. It applies if you are widening an opening, converting a two-car to a three, or rebuilding a header that has dropped, all of which go through the Building Commissioner.
