Garage Doors School

Nobody thinks about a garage door until it stops. Then it is the largest moving thing on the house, it weighs more than the person standing under it, and it has to be fixed today. Somebody has to drive over there and fix it. That is the job, and there are not enough people doing it.

Tuition is $200 and the programme runs one month. At the end of it you are not handed a certificate and a handshake — you are set up as your own business: your own franchise, your own website built for you, and leads provided to you.

Our instructors are working garage door people who teach out of their own offices around the country. You are not learning from someone who wrote a textbook about doors. You are learning from someone who wound a spring this week. The school's hub is at 4360 8th Mile Road, Camino, California.

That structure is the point. Training happens where the instructor is, which means it happens where the work is. Hardware, code, permit desks and market rates all change when you cross a state line, and a teacher who works in your market knows which way they change.

Two things on this site are free to anyone, student or not: verified licensing and permit requirements for all 51 US jurisdictions, and a directory of 10,154 real garage door companies with phone numbers, sorted by state, county and city. Use both whether you enrol or not.

One rule about every page below. Every number carries a source link. Where the trade has no published figure — and for wages, it mostly doesn't — we say so instead of inventing one. There are no earnings claims anywhere on this site, and you should be suspicious of any school that makes them.

What the programme is

$200, one month, and you come out the other side owning something.

Most trade training ends where the hard part begins. You get certified, and then you go knock on doors asking somebody to let you work for them. That is a fine path and plenty of good careers start that way — we tell you exactly how to do it further down this page.

This programme is built differently. You learn the trade from a working technician, and at the end you are set up as a business owner rather than an applicant.

Here is what that means concretely. We are only listing things we can state as fact.

The number that makes this worth reading twice

What it normally costs to own a garage door business in America, taken from published franchise disclosures.

Owning a garage door business is not usually a $200 decision. The established route is to buy a franchise, and those numbers are public because franchisors have to disclose them.

Take Precision Door Service, a national garage door franchise. Per published review of its 2025 Franchise Disclosure Document, the initial franchise fee alone runs $75,000 to $150,000 — priced at $0.50 per single family home unit in the territory — and the total initial investment runs $164,285 to $360,294, before real estate.

Then it keeps costing. That same disclosure lists royalties of 4% to 6% of gross sales on a sliding scale, plus minimum licence fees, plus a marketing fee of 2% of gross sales and local marketing group contributions not to exceed a further 3%. That is a royalty model — the franchisee keeps the large majority of gross revenue and pays a percentage upward — and it is a completely normal way for a franchise system to work.

We are not telling you that model is bad. We are telling you what it costs to enter it, straight out of the disclosure document, so you can hold it next to $200 and one month and decide for yourself which door you want to walk through.

And hold it next to the other number in your life right now: what four years of tuition costs, and what you would still owe on it in your thirties.

What the job actually is

Service calls, spring changes, opener installs, and more commercial dock work than anyone expects.

A residential service day is four to eight stops. You pull up, the customer meets you in the driveway, and the first thing you do is watch the door move. Then you pull the emergency release and lift it by hand. A balanced door stays where you leave it. A door that slams down or shoots up is telling you what's wrong before you've touched a wrench.

From there it's springs, cables, rollers, hinges, bearing plates, drums, track, bottom fixtures, seals, openers, sensors, logic boards and remotes. The parts list is short enough to learn in a season and deep enough to keep you learning for twenty years.

The commercial side is a different animal and it is where a lot of the year-round work lives: rolling steel, sheet doors, high-cycle sectionals, fire doors, dock levelers, seals, bumpers and restraints. Warehouses run doors thousands of cycles a year and they do not wait.

Why this is a real career

No degree, and a broken spring in your town cannot be fixed from another country.

The honest case for this trade is not that it's glamorous. It's that the barrier to entry is your hands and your attendance, the skill compounds, and the work is physically anchored to the place you live.

The ladder is real and people climb it quickly: helper carrying sections, then technician running your own calls, then lead or commercial tech on rolling steel and dock equipment, then a truck of your own, then a business with other people's trucks. This programme is built to start you nearer the top of that ladder than the bottom — but the skills at every rung are the same skills, and you still have to learn them.

What the trade pays, and what we can actually prove

There is no BLS occupation called “garage door installer.” Here is the code that does cover the work, and the one median we can source.

Anyone who quotes a precise national salary for garage door technicians is guessing, because the federal statistical system does not track this trade under its own name. What it does have is SOC 49-9011, Mechanical Door Repairers, and that definition names this work explicitly.

So we will give you the one federal median that genuinely applies to the occupation, and then we will tell you what we are not going to publish. We do not publish a starting wage, a technician's take-home, a “top techs earn” figure, or any income figure for people who complete this programme. Pay in this trade swings hard on market, on whether you are hourly, flat-rate or commission, and on whether you are working for someone or running your own business.

If you want a real local number, call the shops in your city and ask what a helper starts at. There are 10,154 of them on this site with phone numbers.

The spring is the part that kills people

A torsion spring stores enough energy to lift a door with one hand. It does not care which direction it releases.

A torsion spring sits on a shaft above the opening. It is wound to a specific number of turns, and that stored torque transfers through the shaft to cable drums at each end. The cables run down to the bottom fixtures and lift the door. Done right, a 180-pound door feels like ten pounds in your hand.

That energy is present whether the door is open or closed, whether the power is on or off, and whether or not you understand it. It comes out through the winding cone, released by two bars in your hands, a quarter turn at a time. If a set screw is stripped, if the cone is cracked, if a bar is the wrong diameter, or if you use a screwdriver because the bar is in the other truck, the energy comes out through you.

Extension springs are a different failure mode. They stretch along the horizontal track and store the same job's worth of energy in a straight line. When one breaks without a safety cable run through it, it whips.

This is why the homeowner-does-it-himself video is the most dangerous thing on the internet in this trade, and why every legitimate body in the industry prints the same sentence.

The federal rule every residential opener has to meet

16 CFR 1211, UL 325, and the reason there are two little eyes near the floor.

Children were being killed under closing garage doors. CPSC reports that about 73 children between the ages of 2 and 14 were trapped and killed under automatic garage doors from March 1982 onward — about three deaths a year — with others suffering brain damage or serious injuries when a closing door hit them and failed to stop and reverse.

Congress acted, and the result is the federal standard at 16 CFR part 1211, which codifies the entrapment protection requirements of UL 325. Every technician in this trade needs to be able to explain it to a customer in thirty seconds, because you will be asked, and because in four states your ability to legally finish the job depends on it.

The certifications that actually exist

There is no national licence to be a garage door technician. There is one industry credential, and it is real.

Three different things get called “certification” in this trade and they are not the same. IDEA — the Institute of Door Dealer Education and Accreditation — certifies individual technicians by examination. DASMA is the manufacturers' association: it writes technical standards and publishes them free, but it does not certify people. Manufacturers train their own dealers on their own products, which is useful, specific, and does not transfer between brands.

Contractor licensing is a fourth thing entirely, and it is state law. See the licensing section below.

None of the IDEA credentials are legally required to work. They are voluntary. They are also what a serious operator carries, and what a homeowner can look you up by.

Getting licensed where you live

Fifty-one jurisdictions, all verified, all on this site. Read yours before you believe anyone in a comment section.

Contractor licensing in the United States is a state matter, and the rules are not similar to each other. Some states license the business, some license a qualifying individual, some set a dollar threshold below which no licence is needed, some leave it to cities and counties, and some do several of those at once.

This matters more to you than to a helper on somebody else's payroll, because you are going to be running a business. Find out what your state requires before you plan anything else.

We are not going to summarize your state's requirement in a paragraph here, because a paraphrase of a licensing rule is how people end up working illegally. We hold the verified requirement, with the official source and the date we checked it, on the rules page for every state. Go read it.

If you would rather work for someone first

10,154 real garage door companies with phone numbers, sorted by state, county and city.

Plenty of good technicians start on somebody else's truck, and some people want a year of paid reps before they run anything themselves. That is a legitimate route, and the directory on this site is built to serve it whether or not you ever enrol here.

This is a walk-in trade. Shops are small, hiring is informal, and the person who answers the phone is often the owner. Nobody is going to run you through six rounds of interviews for a helper seat. They want to know whether you will show up, whether you can lift, and whether they can put you in a truck.

What goes in your pouch

The short list of what a technician's hands reach for all day.

You do not need a van's worth of equipment on day one, and anyone selling you a “starter kit” for this trade is selling you something. Ask what is provided before you spend money. What follows is what actually gets used.

First week on a truck

How not to get hurt.

Nobody expects a first-week beginner to know anything. They expect you to be where you are supposed to be, to hand over the right tool, and to not put your body somewhere a door is about to be.

Talking to the customer, and what you leave behind

Diagnose first, quote second, document always.

The customer standing in the driveway does not know what a torsion spring is and has just heard a number that sounded large. Everything about how they feel afterwards is decided in the first four minutes.

Show them the broken part. Put it in their hand if it is safe to. Cycle the door in front of them and explain what you are watching. People pay for work they understood, and they call back the person who explained it.

This matters double when the business has your name on it.
