Five minutes of QuickBooks read-only and a few quick questions surfaces what a buyer would discount your garage-door business for — how much of revenue is one-time install versus repeatable service, the maintenance-agreement base they'll grade, and the builder concentration they'll price as risk.

We answer each one from your books first — so you fix the story before a diligence team writes the number.
Install revenue tied to homebuilders is cyclical, lower-margin, and dependent on relationships a buyer can't be sure transfer. Service and repair — the 40–50% gross-margin work that recurs — is what buyers actually pay up for. A shop that's mostly builder install gets priced as the more fragile, more cyclical business it is.
Garage-door buyers pay the most for contracted, renewable revenue — residential service plans and commercial preventive-maintenance agreements on overhead and rolling doors. If most of your top line is one-off installs and break-fix calls, a buyer treats it as harder to repeat and prices it below a competitor with a deep agreement base.
If you personally run dispatch, quote the commercial work, or hold the builder relationships, a buyer sees key-man risk, not a transferable business. A documented service manager who runs the techs without you is the single strongest signal that the company survives your exit.
Clopay, LiftMaster, and Overhead Door dealer authorizations and pricing tiers can hinge on the current owner and may not survive a change of control. A buyer will test whether your supply and pricing advantages are assignable — if they walk out the door with you, so does part of your margin.
Each lever is sized for a typical $2m–$4m revenue garage-door shop, service/repair + install mix — about $400K EBITDA. Same number whether we frame it as “what a buyer discounts” or “what you keep by fixing it.”
Converting install customers to residential service plans and signing commercial buildings to annual preventive-maintenance agreements builds the contracted, high-margin base consolidators reward. It's the highest-leverage play in the trade — it lifts the multiple and smooths the new-construction cycle.
adds about 0.4–0.7× to your multiple · usually takes 12–18 months
Promote a lead tech to service manager with real authority over dispatch and warranty calls, and move the commercial relationships onto them. Turning 'buying the owner' into 'buying a managed shop' is what lets the multiple reach the top of the range — and it's exactly what the PE platforms in this trade screen for.
adds about 0.3–0.6× to your multiple · usually takes 12–24 months
Buyers run a quality-of-earnings review on every deal. Accrual books that separate high-margin service from lower-margin install, backed by a documented add-back trail, let a buyer trust the earnings — and stop a mid-diligence re-trade from clawing back the price.
adds about 0.1–0.3× to your multiple · usually takes 3–6 months
Typical impact ranges blended from lower-middle-market transaction data, sub-$50M M&A databases, and observed consolidator pricing in the $300K–$3M EBITDA band. Directional, not a guarantee — your memo computes your actual numbers from your books.
The metrics buyers grade garage-door contractors on. The diagnostic fills the “your business” column from your actual QuickBooks data.
| Metric | Garage Doors benchmark | Your business | What it means |
|---|---|---|---|
| Recurring / contracted revenue | ~30% of revenue | Your data | Higher is better — the top multiple lever |
| Gross margin | ~55% | Your data | Pricing and job-costing discipline |
| EBITDA margin | ~16% | Your data | What flows to the bottom line |
| Healthy customer-concentration ceiling | top customer under 20% | Your data | Above it, buyers price the risk |
| Typical industry growth | ~4% / yr | Your data | Beating it can add to your multiple |
| Typical sale multiple | 2.5–6.0× EBITDA | Your data | Where the bidding starts; the levers above move you up |

Garage-door services have become one of the more actively rolled-up home-service trades. Private-equity platforms are assembling national footprints — Cortec Group's partnership with A1 Garage Door Service and Blue Ridge Construction Capital's investment in Banko Overhead Doors are recent examples — and PE buyers have been acquiring multi-site Precision Garage Door franchisees. These platforms pay up for service-heavy, manager-run shops with recurring maintenance revenue and route density; regional strategics and individual/SBA buyers compete for smaller install-led shops. The memo maps which would actually look at a company your size and how each tends to structure the deal.

Most Garage Doors businesses in the $1M–$10M revenue range trade at roughly 2.5× to 6.0× normalized EBITDA, with a typical deal near 4.0×. Smaller, owner-dependent shops sit at the low end; larger, manager-run businesses with recurring revenue reach the top. Your actual number depends on your books — that's what the diagnostic computes, blending recent lower-middle-market closings, main-street marketplace sales, and academic M&A survey data.
A garage-door valuation begins where a buyer's QoE team begins: your reported earnings as the starting line. From there, the normalizing adjustments — owner add-backs, family wages, personal vehicles, one-time items — each tied to a specific QuickBooks transaction, producing your normalized EBITDA. Against that we apply a garage-door-specific multiple grounded in recent small-business sale transactions in the trade. The factors that move it up or down: the install-versus-service revenue mix, maintenance-agreement penetration, builder and commercial-customer concentration, whether the business runs without you on dispatch, and whether your manufacturer dealer agreements transfer. Every figure traces back to your books — never a revenue rule-of-thumb.
A high service-and-repair mix, recurring residential service plans and commercial preventive-maintenance agreements, a business that runs without the owner on dispatch, route density, and clean books. The diagnostic scores where you sit on each and shows what moving up would be worth.
