Window cleaning is a fragmented, often cash-heavy industry where valuation depends heavily on one question: how recurring is the revenue? A residential window cleaner doing one-time jobs is a very different business than a commercial window cleaning company with 50 office buildings on monthly contracts.
Window Cleaning Business Multiple Benchmarks
Residential one-time window cleaning: 1.5x–2.5x SDE. High customer acquisition cost, low retention, seasonal in many markets. Residential recurring (monthly/quarterly routes): 2.5x–3.5x SDE. Customers who've committed to a regular schedule behave more like subscription revenue. Commercial route-based (office buildings, storefronts): 3.0x–4.0x SDE. Monthly or weekly contracts, B2B relationships, invoiced billing. High-rise commercial (specialized equipment): 2.5x–3.5x SDE, with premium for established accounts and certified crews.
What Buyers Look For
Buyers in window cleaning focus on: percentage of revenue from route accounts vs. one-time jobs, average contract length and renewal rate, crew structure (does the owner clean windows?), route density (lower windshield time = more jobs per day = better margins), and geographic concentration (a business serving 50 buildings in one downtown district is more valuable than the same revenue spread across 100 miles).
How to Increase Window Cleaning Business Value Before Selling
The fastest value-add moves: convert residential customers to recurring quarterly contracts, pursue commercial bids with monthly billing, document route efficiency (jobs per day per crew), remove yourself from field operations by building a crew supervisor layer, and implement field service software to show organized route data to buyers.
