Garage door company economics: service vs. installs

Two businesses under one roof

A garage door company usually runs two businesses at once. The service business fixes broken springs, frayed cables, off-track doors and failed openers, often the same day, with short visits and a small parts bill. The install business sells and fits new doors and openers, with a quote, a showroom or catalog conversation, a deposit and an installation crew. Both share a phone number, a brand and sometimes a truck, but their economics are very different.

Official statistics do not separate the trade cleanly. The Census classification places residential garage door installation under finish carpentry contractors^[2], a category with 32,219 establishments with paid employees in 2023 and 177,042 employees^[3]. Most are small: 73.5% of those establishments had fewer than five employees^[3]. If you are planning from industry data, treat it as a rough frame and rely on your own job history for margins.

Example: a fictional company's month

Example: a fictional company has two service technicians and one two-person install crew. The figures below show the method; they are not benchmarks for your market.

Example, continued: service looks far better on margin percentage, and installs look better on dollars per job. On gross profit per marketing dollar they are close. Now suppose 8 of the 22 installs came from customers first met on a service call. Those installs needed almost no extra marketing, so the real lead cost of the install business is lower than the table suggests, and the service business is quietly feeding it.

Lead cost: the number that decides growth

Garage door service is one of the most competitive local search categories, and paid lead costs can rise quickly. The useful measure is cost per booked job: total spend on a channel divided by the jobs it actually produced. Cost per lead flatters channels that send many unqualified calls, such as callers outside your area or shoppers asking for a price and hanging up.

1. 01

   Give each channel its own tracking number or tag

   Maps listing, paid search, website form, referral, builder and service-to-install should each be identifiable on the job record.

2. 02

   Record lead source on every booked job

   Make it a required field in your software, chosen from a short fixed list. Free-text sources become useless within a month.

3. 03

   Calculate monthly by work type

   Spend divided by booked jobs, then gross profit divided by spend, separately for service and installs.

4. 04

   Cut or fix the bottom channel

   Move budget from the channel with the lowest gross profit per dollar, or fix its landing page and call handling first.

Call handling is part of lead cost. A broken-spring caller is stuck and will call the next company if nobody answers, and a callback may not be picked up: only 19% of US adults say they generally answer calls from unknown numbers^[4]. Research on web leads found that firms contacting a lead within an hour were nearly seven times as likely to qualify it as firms that waited longer^[5]. Answer live where you can, text immediately when you cannot, and measure how many inbound calls became booked jobs.

Reviews and trust

Homeowners rarely know a garage door company before they need one, so ratings do a lot of the selling. Pew found 82% of adults at least sometimes read reviews before a first purchase and 40% always or almost always do^[1]. The rules are strict: the FTC's 2024 rule bans buying or selling fake reviews, including AI-generated ones^[6], and incentives cannot be conditioned on a positive review^[6]. Ask every customer, at the end of every job, by a link in the receipt text or email.

From service call to replacement, honestly

Garage door companies have a reputation problem with upselling. The way to sell replacements without damaging trust is a consistent, documented inspection on every service call, with photos and a written summary the customer keeps.

1. After the repair, inspect springs, cables, rollers, hinges, tracks and weather seal. Photograph anything worn.
2. Test the opener's safety reversal and sensors with the customer watching. The federal entrapment-protection standard applies to automatic residential operators made on or after January 1, 1993^[7]; older openers may lack those protections.
3. Give the customer three options in writing: keep as is, repair the worn items, or replace door or opener, each with a price.
4. Do not pressure on the day. Send the options by text or email and follow up once after a week.
5. Tag the job as a replacement opportunity in your software so the follow-up does not depend on memory.

Technicians who sell should be paid on gross profit of what they sell, with clear rules, and spot-checked for inspections that recommend replacement too often. A replacement recommendation backed by photos is a service; one without evidence is a complaint waiting to happen.

Pricing service calls so they carry the business

Service margins depend on a clear, consistent price structure. Most garage door companies use a trip or service charge plus flat prices for common repairs: torsion spring pairs by size, cable replacement, roller sets, opener logic boards, sensor alignment. A printed or digital price book makes the price the same whichever technician arrives, which protects both margin and reviews.

• Build flat prices from real job times and parts cost, then review them every quarter as supplier prices change.
• Offer good, better and best options for springs and rollers, with the warranty for each written down.
• Quote the trip charge on the phone and say whether it is credited to the repair.
• Charge a clear after-hours rate and tell the caller before dispatching, not on the invoice.

Avoid two traps. Pricing far below the market to win clicks fills the board with low-margin calls and attracts price shoppers. Pricing much higher on site than on the phone creates complaints that cost more in reviews than the extra margin earned.

After-hours and emergency calls

A door stuck open at night is a security problem, and a car trapped inside is an urgent one, so a share of service demand arrives after hours. Decide in advance which calls you dispatch at night, who is on call, what the after-hours rate is and what the caller hears if nobody can come until morning. Write it down, give it to whoever answers the phone, and track how many after-hours calls became booked jobs. Owners who answer only during the day often find that the competitor who answered at 9 pm also got the replacement sale two weeks later.

Choosing your mix

• Phone coverage: service work depends on answering fast during the day and after hours. If you cannot staff the phone, lean toward installs or arrange coverage before you buy more service leads.
• Cash: installs tie up money in door inventory and deposits. A service-heavy mix keeps cash flowing daily.
• Hiring: a strong service technician needs diagnosis and customer skills; installers need physical capacity and precision. They are different hires.
• Builder and commercial work: steady volume at thin margins, with payment terms. Keep it below the share you could afford to lose.
• Seasonality: cold snaps break springs and openers; spring and summer are strong for door upgrades. Plan staffing around both peaks.

Numbers to review every month

1. Revenue and gross margin, split by service and installs.
2. Cost per booked job and gross profit per marketing dollar, by channel and by work type.
3. Booking rate: inbound calls that became booked jobs, and calls missed.
4. Service-to-install conversion: replacement sales that started as a service call.
5. Callbacks within 30 days, by technician and by job type.
6. Review requests sent and reviews received.

Compare your structure with other trades that mix quick service and larger projects: electrical service vs. construction covers the same trade-off with longer projects, and handyman economics shows how minimums protect short visits.
