How to start a garage door business that answers first and sells doors later

Garage door work is two businesses in one van. The first is urgent repair: a broken spring at 7 a.m., a car trapped inside, a customer who wants someone there today. The second is planned sales: new doors, opener upgrades and insulated doors, sold on style, quality and trust. Repair brings customers in; doors and openers raise the average ticket. The skills are specific, the parts are standardized, and the safety risk around springs is real. Sections below cover the work, spring safety and the opener rule, tools and van stock, pricing, first customers and seasonal patterns.

What does a garage door company fix and sell?

• Spring repair and replacement: torsion springs on a shaft above the door, or extension springs along the tracks on older and lighter doors. A broken spring can leave a heavy door stuck closed, which makes it an urgent call.
• Cables, drums, rollers and hinges: a cable off the drum or a door off track, often after a spring failure or a bumped door.
• Openers: repairs, logic board and sensor faults, remote programming, and replacement with belt, chain or wall-mounted units.
• Tune-ups: lubrication, balance checks, hardware tightening and safety testing, sold as annual maintenance.
• New doors: measured, ordered and installed, from basic steel to insulated and custom styles.
• Commercial work: sectional and rolling steel doors for warehouses and shops, with heavier parts and different training.

Many new companies start residential: repairs, openers and tune-ups, then door sales once they have supplier accounts and showroom samples or a good online catalog.

What safety rules and licensing apply?

Handle the setup basics (entity, EIN, a separate account) with our startup checklist. Everything here is general information and not legal advice; requirements differ by state and city.

Spring safety. Wound torsion springs hold a large amount of energy. Winding bars that slip, the wrong bar size or a cracked cone can cause serious injuries. Learn winding and unwinding under an experienced technician, use bars that fit the cones, and never stand in line with the bar. Follow the door and spring manufacturer's instructions for every replacement.

The federal opener rule. Under 16 CFR Part 1211, the Consumer Product Safety Commission's standard applies to all residential garage door operators manufactured on or after January 1, 1993 for sale in the United States. It requires inherent primary entrapment protection plus one of several secondary options: constant-pressure control, a way to connect an external secondary device such as a photoelectric sensor or door edge sensor, or, on certain combination door and operator systems, an inherent secondary device. For vertically moving doors, the primary protection rule requires the opener to start reversing a closing door within 2 seconds of contact with an obstruction (the first foot of travel from fully open is excepted). Manufacturers build openers to meet this; your job is to install them as instructed, set the force and travel limits correctly, align the photo eyes, and test reversal before you leave. Note it on the invoice. If an old opener has no working safety reversal, tell the customer in writing and recommend replacing it.

Licensing. Some states license garage door work under contractor or home improvement licensing, and some cities require a contractor registration or permits for new door installs. Electrical work beyond plugging an opener into an existing outlet may need a licensed electrician. Find your state's licensing boards through our state startup pages before your first job, and see the contractor license guide for how the process usually works.

Insurance. General liability (doors fall, cars get scratched, springs break things), commercial auto for the van, coverage for parts inventory in the vehicle, and workers' compensation as your state requires for employees. Our contractor insurance guide explains the policies and certificates.

What tools and van stock does a garage door tech need?

• Spring tools: properly sized winding bars, a spring gauge or wire-size tool, locking pliers and C-clamps to hold the door, and a torsion spring calculator or chart.
• General tools: impact driver, sockets, drill, level, ladders, a stud finder, cable cutters and a multimeter for opener diagnostics.
• Spring stock: the wire sizes and lengths most common on doors in your market, in pairs, plus extension springs and safety cables.
• Parts stock: cables, drums, bearings, rollers, hinges, center brackets, weather seal, opener sensors, logic boards and remotes for the brands you see most.
• Openers: a few common models on the van for same-day replacement.
• A van with shelving and a ladder rack, organized so you know what is on board.

Open accounts with a garage door distributor and learn their lead times for doors. Track which parts you use each week and restock from that list; a tech who has to leave for a part can lose the morning, and sometimes the customer.

How should you price garage door repair?

Customers in a hurry want a number on the phone. Flat-rate pricing makes that possible:

• A service call fee that covers the trip and diagnosis, credited toward the repair if they approve it.
• Flat prices for common repairs: a pair of torsion springs, cables, rollers, an opener sensor, a door off track. Give a range on the phone and the exact price after inspection, before you start.
• Options on site: standard springs or higher-cycle springs, replace only the broken part or the full hardware set. Explain the difference without pressure.
• New doors and openers: priced from distributor cost by size, style, insulation and windows, plus install and haul-away of the old door.
• Tune-up plans: an annual visit at a set price, with a discount on repairs.

Our pricing guide shows how to set your hourly floor so flat rates cover drive time and callbacks. Explain on your website how you price (service call fee, flat rates, written price before work starts), so the customer knows what to expect before you arrive.

How do you get garage door customers?

• A phone that is always answered. A caller with a stuck door who reaches voicemail can simply call the next listing. Answer live, give a time, and book the visit on the call. Our AI receptionist can answer when your techs cannot, book the visit and flag emergencies like a door stuck open at night.
• A Google Business Profile with your actual service area (or address, if customers visit), hours that match when you take calls, and reviews that mention specific repairs. See our Business Profile guide.
• A fast website with pages for spring repair, opener repair, new doors and each town you serve, with a click-to-call button at the top. See websites.
• Builders, realtors and property managers for door replacements on flips, rentals and new construction.
• Your own repair customers. Note the door's age, condition and opener model at every repair, then follow up a few months later with door and opener options.

Pay-per-lead platforms can put one caller in front of more than one company. Angi's FY2025 10-K says a single service request can result in multiple leads, and that pros pay for consumer matches regardless of whether they end up providing the service. Thumbtack's Quality Commitment caps the pros a customer can contact at five for the first four hours of a search, and lifts the cap after that. Customers who find you through your own profile and site, and repeat customers, come with no per-lead fee. The garage door industry page walks through the phone, site and CRM work we do for this trade.

Which systems should a garage door company set up?

• A CRM with door records: door size, spring specs, opener model, parts used, photos and safety test results for every address. The next tech can bring the right springs on the first trip. See our custom CRM.
• Dispatch by urgency: a car trapped inside or a door that will not close outranks a noisy opener.
• Quotes on site with options and card payment from the driveway.
• Follow-up for door sales after repairs on older doors, and annual tune-up reminders. Our missed-call text-back guide covers catching the calls you cannot answer.

How seasonal is garage door work across the US?

• Cold climates: doors that freeze to the ground, weather seals that crack and openers straining against stiff hardware can add winter calls. Market insulated doors in early fall, before customers feel the cold garage.
• Hot climates: sun and heat are hard on weather seals, and insulated doors can be sold as a way to keep garages cooler. Work can run most of the year.
• Storm and coastal regions: wind-rated doors and reinforcement are a product line, and local building codes may set wind-load requirements for replacement doors. Check your local code.
• Everywhere: repair demand tends to be less seasonal than in many trades because springs fail on their own schedule. Door sales tend to follow home sales and remodeling.

Garage door companies that want a second line sometimes add handyman services or work alongside concrete contractors on garage slab and apron projects.
