Five minutes of QuickBooks read-only and a few quick questions surfaces what a buyer would pay up for — and discount — in your window-cleaning business: how much is recurring commercial route work versus one-time residential, how dense the routes are, and whether the jobs get sold without you.

One-time residential washes don't repeat — you re-win the year every January. Recurring commercial route contracts (storefronts, offices, properties) are what buyers pay up for; a quarterly recurring customer is worth many times a one-time deep clean. A book that's mostly one-and-done residential gets priced as the churny revenue it is.
In most window-cleaning shops the owner books the work, quotes the commercial bids, and holds the accounts. Because barriers to entry are low, a buyer discounts hard for revenue that depends on the founder still selling — an SBA-backed or search-fund buyer is underwriting whether the work keeps coming after you leave.
In a low-ticket trade, route density — billable hours on glass versus hours in the truck — is the margin engine. Scattered jobs burn drive time and cap crew utilization, so a buyer prices a thin, spread-out route below a clustered one even at the same revenue.
If you do high-rise or rope-descent work, your safety record, OSHA compliance, and insurance posture feed directly into a buyer's risk and cost view. A thin safety record or weak documentation raises their carried cost and lowers what they'll pay; one big commercial account dominating the book adds concentration risk on top.
Each lever is sized for a typical $700k–$1.5m revenue window-cleaning company, residential + commercial mix — about $150K EBITDA. Same number whether we frame it as “what a buyer discounts” or “what you keep by fixing it.”
Scheduled commercial route contracts (monthly/quarterly storefront and office accounts) and recurring residential plans convert one-time washes into a contracted base. It changes which buyers will look at you and lifts the multiple — recurring revenue is what the franchise and platform buyers in this space prize.
adds about 0.3–0.6× to your multiple · usually takes 12–18 months
Promote or hire an operations/crew manager who can quote and win work, and document your bidding method. A window-cleaning business that sells and runs routes without the owner stops being 'a job,' which opens the broader buyer pool where higher multiples are set.
adds about 0.4–0.7× to your multiple · usually takes 12–24 months
Clean accrual books with a documented add-back trail and contract documentation that proves the recurring route base let a buyer trust the numbers — which protects the price you've already earned from a mid-diligence re-trade.
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 window-cleaning companies on. The diagnostic fills the “your business” column from your actual QuickBooks data.
| Metric | Window Cleaning benchmark | Your business | What it means |
|---|---|---|---|
| Recurring / contracted revenue | ~35% of revenue | Your data | Higher is better — the top multiple lever |
| Gross margin | ~50% | Your data | Pricing and job-costing discipline |
| EBITDA margin | ~15% | Your data | What flows to the bottom line |
| Healthy customer-concentration ceiling | top customer under 15% | 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 | 2.5–4.5× EBITDA | Your data | Where the bidding starts; the levers above move you up |

Window cleaning is a fragmented, low-barrier trade where recurring commercial routes are far more valuable than one-time residential. Buyers are mostly individuals and search funds using SBA financing, plus franchise systems and PE-backed exterior-services platforms — Fish Window Cleaning (the largest franchise), Window Genie (a Neighborly brand), Shine (acquired by Riverside-backed Evive Brands), Men In Kilts, and Shack Shine — rolling up route density and commercial contracts. The ones who pay up want recurring commercial revenue, route density, high-rise capability with a clean safety record, and a manager-run operation. The memo maps which would actually look at a company your size and how each tends to structure the deal.

Most Window Cleaning businesses in the $1M–$10M revenue range trade at roughly 2.5× to 4.5× normalized EBITDA, with a typical deal near 3.5×. 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 window-cleaning 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 multiple grounded in recent cleaning-services and small-business sale transactions. Because the trade is low-barrier, buyers look hard at how much revenue is recurring commercial versus one-time residential, route density, high-rise safety, customer concentration, and whether the work gets sold without the owner. Every figure traces back to your books — never a revenue rule-of-thumb.
Recurring commercial route contracts, recurring residential plans, route density, high-rise capability with a clean safety record, a non-owner sales and operations function, and clean books. The diagnostic scores where you sit on each and shows what moving up would be worth.
