## Why Searchers Target Garage Doors

Private equity calls garage doors the new HVAC, and the money shows it: 26 PE-backed deals closed in 2025, and Oak Hill Capital bought Guild Garage Group for about $800 million. The pull is a services trade that behaves like plumbing or HVAC, install plus repair and maintenance, but is a decade behind in consolidation, so the field is still thousands of local shops. Demand is steady and partly non-discretionary, since a broken door people use daily gets fixed, and the repair-and-service half is recurring and recession-resistant in a way new-construction install is not. A searcher can buy a local shop below the consolidators' attention and, if they build the service book, exit into the roll-up wave the next sections explain.

## What Garage Door Businesses Trade For

Garage door has no benchmark page of its own, and is not a category in the publisher's taxonomy at all, so the nearest published ground is its building and construction class. In that class the publisher records half of 3,142 sold businesses clearing 1.81x to 3.13x SDE on a $750,000 median sale price. Read that as a placement rather than a measurement of this trade. The EBITDA tiers advisers quote for multi-truck and mid-market operators sit at roughly double that upper quartile with nothing behind them, and platform headlines are the exit rather than the entry. Where a shop lands is mostly the service-versus-install split the next section covers, not the top line.

## Service Against Install

The single most important number is the service mix. Repair, service calls, and maintenance are recurring, higher-gross-margin, and largely detached from housing starts; new-door installation is project revenue that is lumpier, lower-margin, and rises and falls with construction and home sales. Buyers pay a premium for the service half, and a book that crosses roughly half its revenue from service and repair sits at the top of its band. Commercial service, doors for warehouses and multifamily on a maintenance relationship, is stickier still. Read revenue split by service versus install and by residential versus commercial, because a shop big on install volume is a cheaper, more cyclical business than a smaller one built on service.

## Route Density, Techs, and the Consolidators

Two operating facts and one market fact round out the read. Route density drives margin: trucks that cover a tight metro run more jobs per day than the same crew spread across a region. Technicians are the constraint and the asset, because garage door repair is skilled and safety-sensitive, so trained techs and the shop's International Door Association standing are worth diligence, and losing the crew can lose the service quality that holds the book. The market fact is that consolidators like Apex and Wrench Group are actively buying and cross-selling garage doors, which is both the exit and the competition. It lifts prices for good service books, but means a searcher should not overpay chasing a platform multiple on a mostly-install shop.

## What to Verify in Diligence

The record to assemble before the offer holds:

## Financeability Notes

Garage door companies finance under SBA 7(a), often paired with equipment financing for the truck fleet, and lenders read a service-heavy book as steadier than install-led revenue tied to construction. Expect underwriting to weigh the service-versus-install mix and the fleet's condition, since an install-heavy shop carries the housing cycle a lender prices. Model debt service net of a market wage for a lead technician and a manager if the seller runs the calls, and net of the truck and equipment capex the routes need. The margin risk to underwrite is a construction slowdown against an install-weighted book, so read the recurring service share, not just the trailing revenue.

## What this guide verified

- The publisher lists no garage door category at all. Its building and construction class is the closest published band, and half of 3,142 businesses sold there cleared 1.81x to 3.13x SDE on a $750,000 median sale price. Read that as a placement rather than a measurement of this trade, and treat the EBITDA tiers advisers quote as unevidenced.

- Private equity is consolidating garage doors as the next home-services roll-up after HVAC, with 26 PE-backed deals in 2025 and Oak Hill Capital's roughly $800 million purchase of Guild Garage Group. Platform pricing has reached mid-teens EBITDA multiples, well above the small-shop SDE range a searcher buys in.

- The roll-up wave reaches searcher scale: operator-buyers are assembling garage door platforms from local shops with SBA financing and seller rollover, treating the recurring service book as the asset the consolidators ultimately pay a premium for.

## Terms of the trade

- **Builder versus service mix**: New-construction installs against repair calls on doors that already exist. Builder work arrives in volume, pays late, and disappears with a housing cycle; service work arrives one call at a time, pays on the day, and does not care what rates are doing. A book weighted to builders is a bet on a market, and it prices lower for exactly that reason. Ask for the revenue and margin split across three years, and read a heavy builder share in a strong year as the cyclical exposure it is. Then ask how the service calls arrive: a company with a maintenance base and a callback list owns its demand, while one buying leads every month is renting it at whatever this year's price is.
- **Spring cycle rating**: The number of open-and-close cycles a torsion spring is built to survive before it breaks. Springs are the recurring revenue under a service book and the reason that book is worth more than an install book. A standard spring is rated for a fixed number of cycles, commonly quoted around ten thousand. That is a few years for a household opening the door several times a day and much less for a busy one, so every door in the territory is on a clock whether anybody is tracking it or not. Ask what share of service calls are spring replacements, and whether the shop stocks the higher-cycle spring, because selling that upgrade is a margin decision made at the customer's curb.
- **IDA Certified Door Dealer**: A trade accreditation covering technician training, safety, and service standards. It is the credential buyers look for, and the trained technicians behind it are the asset that actually holds the service book together. Ask who on staff carries the training, how long they have been there, and what it would cost to replace them, because in a trade this short of technicians the answer is usually more than the accreditation itself is worth. The certificate is a signal; the people are the business.
- **Van stock**: The parts a technician carries on the van, which decide whether a call is finished on one visit. A garage door call is won or lost on whether the spring, opener, or panel needed is already on the van. A second trip costs a technician half a day and usually costs the review as well. Ask what share of calls close on the first visit and what the van inventory is worth, then check whether the shop stocks the brands actually installed across its territory. A shop buying parts job by job rather than carrying stock is showing you a working capital increase that you will be the one to fund.
- **Entrapment protection**: The federal safety standard behind every opener, and the party it actually binds. It binds manufacturers and importers, not the installer. The standard requires an opener on a downward moving residential door to begin reversing within two seconds of meeting an obstruction, and the compliance statement is a label on the product carrying the year of the standard it meets. Testing is the manufacturer's duty, either unit by unit or under a reasonable testing program. So a buyer inheriting an installation book inherits no federal record duty at all. What it does inherit is the contractor's own file, which California makes a disciplinary matter if it cannot be produced to the registrar for five years after a project is completed.
- **Wind load rating**: Florida's statewide product approval a door must hold before installation, inland included. The geography most people assume is wrong. Florida requires a product to be approved before its use in construction anywhere in the state, and statewide approval then stops a local jurisdiction from demanding further testing. The wind-borne-debris region decides how much pressure and impact a door must take, not whether approval applies, so an inland shop sits inside the same regime as a coastal one. Doors are approved as exterior door assemblies and not as structural components, and the approval carries its installation instructions with it. A building official may still refuse a particular installation, by written report saying why it is inconsistent with the approval. The commercial teeth sit on whoever markets a product as hurricane protection without approval, which is a deceptive trade practice.
- **Red certificate**: California's tag, attached when an existing garage door opener fails the two-inch reversal test. Entrapment protection is the standard behind a new opener, and this is what a company owes on the openers already on the wall. The federal rule binds manufacture only, and the words existing and retrofit appear nowhere in it. Outside California a buyer therefore inherits a contractual and insurance question, not a regulatory one, bounded by whatever repose statute the state gives latent construction defects. California is the exception and it is priced per unit. Since 1993 anyone hired to service or repair a residential opener must test whether it reverses over a rigid two-inch obstacle and, on failure, affix a red certificate to it. Since 1992 no replacement door may be connected to an existing opener that fails that test, whatever the opener's age, and a battery-backup version of the rule arrived in 2019. Penalties run per opener and an affected consumer can bring the action and keep the money. So a California door book carries a higher legitimate ticket, because a door job on a legacy opener is a forced opener sale, and a door-only mix that looks unusually high is a finding. Ask to see the certificates.
