Residential Window Cleaning

Window cleaning is one of the cleanest entry points into the home-services game: almost no capital, no license in most states, and a job a motivated person can learn well in an afternoon. The catch is that "easy to start" also means "easy for everyone else to start." You win on recurring routes, reliability, and looking like a real business, not on having a secret squeegee technique.

Why this niche

The US window-washing industry is worth about 2900000000 (2024). It is brutally fragmented: roughly 44000 mostly-independent operators, with the top four firms generating less than 5% of total revenue. That fragmentation is the opportunity. There is no dominant brand to outspend, and a tidy, dependable local operator can carve a route out of a single zip code.

The demand is sticky. Industry summaries put roughly 80 percent of sales as coming from repeat clients. Glass gets dirty again on a schedule, which means a satisfied customer is a quarterly or twice-a-year annuity, not a one-off transaction. That recurring nature is what turns a side hustle into a real cash-flowing business.

The honest downside: margins are thin at the industry level (commonly cited in the low single digits to ~10% for firms carrying overhead and payroll). A solo owner-operator keeps far more, because the dominant "cost" is their own labor. This is a business where your moat is your own time and your route density, not a fat structural margin.

The economics

Residential pricing typically runs 10-$18 per window (or $4-$8 per pane), which works out to roughly $150-$275 for a small home, $250-$450 for a medium home, and $450-$900+ for a large home. A solo operator who can complete two to three medium homes a day is generating $500-$1,200 of revenue against almost pure-labor cost.

Startup is genuinely cheap. A basic kit (squeegees, scrubbers, buckets, an extension pole, solution, a ladder) runs $300-$800; add insurance, a website, and cards and you are typically still under $2,000. A water-fed pole system ($500-$2,000) unlocks safe two-story exterior work without ladders and is the single best upgrade once you have cash flow.

Saturation reality check

Saturation score: 62 / 100 (estimate). High enough that "I'll just start a window cleaning business" with no plan lands you in a price war with a dozen guys on Facebook Marketplace. Low enough that almost none of those competitors run like an actual business — online booking, on-time arrival, uniformed appearance, follow-up reminders, reviews. Do those four things and you stop competing on price.

How to start (step-by-step)

• Pick a tight geographic zone. Choose one to three adjacent neighborhoods, ideally with mid-to-high home values and lots of glass. Route density is everything; you make money driving less and cleaning more.
• Buy the minimum viable kit ($300-$500). Two squeegees (a 14" and a smaller detail size), a strip washer/scrubber, a bucket, an extension pole, a quality solution (dish soap + water works to start), microfiber towels, and a sturdy ladder. Don't buy a water-fed pole yet.
• Register the business and get liability insurance. Most states require no special window-cleaning license, just a general business registration. Get general liability insurance before your first paid job; one broken window or a fall claim can wipe out a season of profit. Verify your specific state and city requirements with your Secretary of State and local business-license office.
• Set transparent per-window pricing. Publish a simple rate (e.g. $12/window inside-and-out, minimum $150 trip charge). Clear pricing closes jobs faster than "call for a quote" and filters out tire-kickers.
• Get your first 5 jobs at near-cost. Offer friends, family, and your target neighborhood a discounted first clean in exchange for permission to take before/after photos and a review. These five jobs are your portfolio and your proof.
• Build the proof asset. Take crisp before/after photos of every job. Stand up a one-page website and a Google Business Profile. Reviews and photos on Google are the cheapest customer-acquisition engine in this trade.
• Door-knock and leave-behinds. After you finish a house, knock on the 4-6 nearest doors: "I just cleaned the Johnsons' windows next door, want yours done while I'm here?" Same-street upsells are nearly free revenue and build route density.
• Convert one-offs into recurring plans. At checkout, offer a recurring schedule (quarterly / twice-yearly) at a small discount. This is the entire game. A book of 50 recurring residential clients at ~$300 each, serviced 2-4x/year, is a predictable five-to-six-figure business.
• Reinvest into a water-fed pole and a helper. Once you have steady cash flow, the water-fed pole speeds two-story exteriors and improves safety, and a single helper lets you nearly double daily job count. This is the step that moves you from ~$90K solo toward the ~$180K range.
• Track and tighten your route. Group recurring clients by day and zone so you minimize windshield time. Density, not heroic hours, is what raises your effective hourly rate.

Bottom line

Low cost, fast first dollar (often within 7 days), and recurring revenue make residential window cleaning a legitimately good first service business. Treat the easy entry as a warning, not a gift: the operators who win are the ones who run it like a company from day one and obsess over recurring routes.
