How Buyers Actually Value a Garage Door Business (and Why Two Similar Companies Sell for Different Multiples)
- Aug 3

Two garage door companies can look almost like twins on paper. Same revenue. Same headcount. Same size of market. And yet one sells for meaningfully more than the other.
That's what happened to Greg. At a trade conference last year, he ran into an old friend, another garage door business owner whose company looked, from the outside, a lot like his own. The friend had sold eighteen months earlier, and Greg finally worked up the nerve to ask what he'd gotten for it.
The number surprised him. Not because it was impossibly high, but because it was noticeably higher than what Greg had assumed his own business would be worth.
That gap is more common than most owners realize, and it comes down to a simple truth: buyers don't value garage door businesses on revenue. A handful of factors most owners have never thought to measure move that number more than anything else.
Garage Door Business Valuation: The Number Buyers Actually Price
Buyers price businesses off earnings, not the top line. For larger, more established companies, that usually means EBITDA: earnings before interest, taxes, depreciation, and amortization. For smaller, owner-operated businesses, it's more often seller's discretionary earnings (SDE), which adds the owner's salary and benefits back into the mix, since a single owner-operator typically draws compensation differently than a company with a hired management team would. Most garage door businesses selling in the "Main Street" range, roughly under $2 million in value, are priced on SDE. Once a business clears that range and has real management depth, EBITDA becomes the standard.
Either way, the starting point is your net income, adjusted for interest, taxes, depreciation, and amortization. From there, a good advisor goes further, adjusting for owner compensation above what a hired manager would cost, personal expenses running through the business, and one-time costs that won't continue under new ownership. What's left is your adjusted earnings, and it's the real foundation of your valuation.
Two businesses with identical revenue can land on very different adjusted earnings once these adjustments are made. That's often the first place similar-looking companies start to diverge in value.
Why the Multiple Varies So Much Between Similar Businesses
Once a buyer has your adjusted earnings figure, they apply a multiple to arrive at a purchase price. That multiple is where two nearly identical businesses can end up selling for very different amounts, and deal size alone moves it more than most owners expect.
According to the IBBA and M&A Source Market Pulse survey, which tracks business sale data across the U.S. each quarter, businesses under $500,000 in value have recently traded around 2.3 times earnings, while businesses in the $5 million to $50 million range have traded closer to 5.5 times earnings.¹ Bigger, better-run businesses simply command a bigger multiple, on top of whatever revenue growth got them there.
Inside any given size range, a few factors do most of the work in pushing that multiple up or down:
Recurring revenue
A garage door business with a strong base of commercial maintenance contracts and repeat service agreements looks fundamentally different to a buyer than one running almost entirely on new installs and one-time repair calls, even at the exact same revenue level. Predictable revenue lowers a buyer's risk, and buyers pay a real premium to lower risk.
Customer concentration
If a large share of revenue comes from a handful of commercial accounts or a single builder relationship, that's a dependency buyers price as risk. Losing one relationship after the sale could meaningfully change the business they thought they were buying.
Owner dependency
If techs call the owner for pricing on every unusual job, if long-standing customers only trust the owner personally, or if key vendor relationships exist because of the owner's individual history with someone, all of that is transition risk. The more a business can run without the owner in the middle of every decision, the more transferable it is, and transferability is exactly what drives a premium multiple.
Growth trajectory and market position
A business that's grown steadily over the past two to three years tells a buyer that demand is real and the operation can capture it. Being the established player in a market a buyer wants into adds strategic value beyond the raw financials.
What Pulls a Multiple Down
Disorganized financials quietly cost more owners than almost anything else. Unexplained swings in revenue, undocumented add-backs, and records that require real effort to untangle give buyers a reason to discount whatever they can't independently verify. It's not that buyers assume the worst. They simply can't pay for what they can't confirm.
This is often the real explanation behind two similar-looking businesses selling for different amounts. It's rare that one business is dramatically better run than the other. It's usually that one owner could clearly document and defend their numbers, and the other couldn't.
What This Actually Looked Like for Two Real Businesses
Greg's friend, it turned out, had spent nearly a year before going to market building out his maintenance agreement base, documenting his add-backs with real paper trails, and putting a service manager in place so techs weren't calling him directly for every decision.
Greg hadn't done any of that yet. Same revenue, same market, meaningfully different multiple, because the buyer wasn't just pricing the business as it existed on a spreadsheet. They were pricing the risk, and the risk profile of the two businesses wasn't actually the same at all, even though the top-line numbers looked nearly identical.
That conversation changed how Greg thought about his own business almost immediately. He stopped assuming his revenue told the whole story and started asking what specific things he could do, starting now, to close that gap before he ever had a real conversation with a buyer of his own.
