Raise your garage door about halfway and look at the inside face of the top section, near one end. Most steel doors carry a label there with a model number on it, and on a lot of doors that label is the only honest record of what you own. Homeowners almost never look at it. They ask where the door was made instead, which feels like the same question and is not, because two doors from the same manufacturer can differ in steel thickness, insulation, hardware grade, and weight by a margin wide enough to change what springs the door needs.
With thousands of 5-star ratings across Google, Yelp, Facebook, and Thumbtack, Local Garage Doors installs and services Clopay doors across California, Nevada, and Arizona, and we spend a fair amount of every quoting conversation explaining that the brand on the door is the beginning of the answer rather than the end of it.
If you are trying to work out what you have, or trying to decide what to buy, this article is about reading the model number instead of the badge. For same-day service, call

The Short Answer
Clopay is an American manufacturer and builds its residential doors domestically. That is the whole of the factory answer, and it is worth exactly as much as it sounds — which is to say it tells you the door was made competently, and nothing about which door you are looking at.
The reason the question gets asked so often is that people are really asking something else: is this a good door, will parts be available, and how does it compare to the one the other contractor quoted. Those questions have answers. They just live in the model number.
Why the Same Brand Builds Very Different Doors
A large door manufacturer does not build one product line. It builds several, aimed at different buyers and different price points, and it also builds doors that carry other companies’ names.
Clopay is a clear example. Alongside its own dealer collections, it builds the Holmes Garage Doors and Ideal Door private labels. Those are Clopay-manufactured doors sold under different brand names through different channels. Our Clopay page publishes the full model-number lists for the dealer line, the retail line, and both private labels, which is unusual for a service company to put online and is the reason we can usually identify a door from a photograph of its label.
The practical consequence is this. A homeowner with a Holmes door and a homeowner with a Clopay door may own doors from the same production line. A homeowner with two Clopay doors — one from a dealer collection, one from the retail line — may own doors with meaningfully different steel, different insulation, and different hardware. The badge does not separate them. The model number does.
What the Model Number Actually Tells a Technician
Construction layers. Whether the door is single-layer steel, two-layer steel with insulation, or three-layer steel-insulation-steel. This is the biggest single driver of both weight and how the door behaves in a hot garage.
Insulation type and value. Whether the core is polystyrene, polyurethane, or nothing at all. Our guide to insulation options covers what the difference means in practice.
Panel design and finish. Which of the collections it belongs to — raised panel, stamped carriage house, flush panel, overlay, or full-view aluminum — which determines what a matching replacement section looks like.
Weight. The number that matters most for service. A single-car steel door runs 90 to 140 pounds non-insulated and 180 to 230 pounds in a triple-layer build. A double-car steel door runs 180 to 250 pounds non-insulated and 300 to 400 pounds or more triple-layer. That is a spread wide enough that two doors of the same size and the same brand need entirely different springs.
Section availability. Whether a single damaged panel can be matched, or whether the collection has been discontinued and panel replacement means matching a door that is no longer built.
That last one is the reason to write your model number down today rather than on the day a car meets the bottom section.
Where to Find Your Model Number
The inside face of the top section. Most common location. A printed or foil label near one end, often close to the top corner.
The inside of an end stile. On some doors the label sits on the vertical edge member at either side of a section rather than on the face.
The bottom section, inside. Less common, and the label is often the first casualty of a wet garage floor.
Your original paperwork. The install invoice or the manufacturer’s warranty card carries it, if the door was installed by a company that documented the job.
If the label is gone — faded, painted over, or removed — a technician can usually narrow the door down from the panel profile, the section height, the stile construction, and the hardware. That identification is part of what happens during a safety inspection or a service visit.
What the Factory Question Can’t Tell You
Whether the door was installed correctly. Manufacturer warranties cover the door and hardware against defects. They do not cover installation workmanship, and the majority of premature door problems we correct are installation issues rather than manufacturing ones.
Whether the springs were sized to the door. The manufacturer builds the door. Whoever installed it chose the spring, and if they chose it from a truck stock rather than from the door’s actual weight, the door has been undersprung or oversprung since day one.
How the door will hold up in your climate. A door built to the same standard behaves very differently in coastal salt air than it does in a Phoenix garage.
What your warranty actually covers. Warranty terms vary by product line and by collection, which is another thing the model number resolves and the brand name does not.
Regional Notes on Door Selection
Salt air in San Diego, Coronado, Encinitas, and Half Moon Bay. Coating condition and hardware grade matter more here than panel style. Steel doors are hot-dip galvanized, but the collections differ in finish quality above that base layer, and the difference shows up at the coast first.
Extreme heat in Phoenix, Chandler, Goodyear, and Las Vegas. Garage interiors exceed 120°F in summer and Phoenix garages reach 130°F. Insulated construction is not only a comfort question in that range; it changes how much the panels move and how the finish ages.
Central Valley heat cycling in Sacramento, Stockton, Modesto, and Woodland. Wide daily temperature swings work on panel joints and on the finish. Two-layer and three-layer construction handles that cycling better than single-layer steel.
Freeze-thaw at Lake Tahoe, Truckee, and Carson City. Insulation value earns its keep, and so does a bottom seal specified for cold.
Newer builds in Summerlin, Henderson, Anthem, and the Sacramento suburbs. Builder-grade doors are frequently retail-line or private-label products. That is not a criticism of the door; it is a reason to check the model number before assuming the door on your neighbor’s identical house is the same door.
What This Means When You Buy
Ask for the model number in the quote, not just the collection name. A quote that names a collection but not a model leaves room for a different door than the one you looked at.
Ask what the door weighs, and ask what spring is being installed against that weight. Those two answers together tell you more about the quality of the installation than any brand discussion will. A balanced door has the springs doing about 95% of the lifting and the opener 5%, and that split only happens when someone did the arithmetic.

The Bottom Line
Clopay builds its residential doors in the United States. That is true, and it is the least useful true thing you can know about the door on your house.
The model number is the useful part. It tells a technician the construction, the insulation, the collection, the weight, and whether a matching section can still be ordered — and weight is what determines the spring, which determines whether the door is balanced, which determines how long the opener lasts.
Go find the label on the inside of your top section and photograph it. If it is gone, have it identified during your next service visit. Whatever the badge says, the number under it is what a technician will ask for.

Frequently Asked Questions About Clopay Garage Doors
Are Holmes and Ideal Door the same as Clopay?
They are private-label brands built by Clopay and sold under different names through different channels. The construction is not identical across every model, which is exactly why the model number matters more than the label on the outside.
Where do I find the model number on my garage door?
Most often on the inside face of the top section near one end. Check the inside of the end stiles and the bottom section as well. If you have the original install paperwork or warranty card, it will be there too.
Does the model number affect what a repair costs?
It affects what parts are needed and whether they can be sourced. Springs are sized to door weight, and door weight comes from construction, so the model number is the shortest path to the right spring. Spring replacement runs $250 to $850 depending on door size, spring quality, and whether it is a single- or two-spring system.
Can you match a single damaged panel on an older door?
Sometimes. It depends on whether the collection is still in production and whether the panel profile is still built. Identifying the door is the first step, and it is why the model number is worth recording before you need it.
Does Local Garage Doors only install Clopay?
No. We install and service CHI, Wayne Dalton, Clopay, Amarr, Martin, Raynor, Door Link, Overhead, MidAm, Garaga, NorthWest, Unique, 1UDT, Windsor, Carriage House, Alumadoor, and TrendView. Our top manufacturers section covers the main lines.
Is a more expensive collection worth it?
It depends on your climate and how the garage is used. In coastal and desert conditions, construction and finish quality change how the door ages. On a detached garage in a mild microclimate, they matter less. The material types comparison is the place to start.
What does the manufacturer’s warranty actually cover?
The door and its hardware against defects. Terms vary by product line, which is another reason to have the model number. Warranties do not cover installation workmanship, and they do not cover wear items like springs and cables.
