Starting a window cleaning business is one of the more accessible service-based businesses to launch, but “easy to start” and “easy to profit from” are two different questions. This guide breaks down what it actually costs to start a window cleaning business in 2026, how much operators realistically earn, where the margins get squeezed, and which risks catch beginners off guard.
Quick Answer: A window cleaning business typically costs between $1,100 and $34,000 to start depending on scale, generates $27,000–$375,000+ in annual revenue depending on whether it’s run solo or with a crew, and produces net profit margins between roughly 27% and 66% after taxes. Break-even for a solo operator using traditional equipment is usually 1–3 months; for a fully-equipped commercial setup with a van and employees, it can take 12–24 months to recover the initial investment.
1. Quick Answer
| Metric | Value |
|---|---|
| Startup Cost | $1,100 – $34,000 |
| Annual Revenue | $27,000 – $375,000+ |
| Net Profit | $16,400 – $220,000 |
| Profit Margin | 27% – 66% |
| Break-even | 1 – 24 months (scale-dependent) |
| Difficulty | 4/10 |
| Scalability | 7/10 |
A solo, traditional-tools window cleaning operation is one of the cheapest legitimate service businesses to start — a few hundred dollars in squeegees, buckets, and a ladder can technically get someone working. But the numbers above hide a wide range: a part-time solo operator working evenings and weekends is a fundamentally different financial proposition than a company running multiple crews and vans. The rest of this guide walks through both ends of that range, and everything in between, with the underlying math shown.

3. What Is This Business?
A window cleaning business provides interior and exterior glass cleaning services to homeowners, commercial property managers, and retail businesses. The core service is straightforward — soap, squeegee, and a system for reaching upper-story glass safely — but the business model varies significantly depending on who the customer is.
How it makes money: Residential customers typically pay per visit, often on a seasonal or semi-annual schedule (spring and fall are the most common service windows). Commercial customers — especially storefronts and office buildings — often sign recurring contracts, paying monthly or biweekly for a consistent, always-clean appearance. Real estate agents and property managers sometimes hire one-off cleanings ahead of showings or move-ins.
Who pays and why: Homeowners pay because clean windows are one of the most visible, easily-noticed forms of home upkeep, but one of the more tedious and mildly risky (ladder work) to do themselves. Commercial clients pay because dirty storefront glass directly affects how a business looks to walk-in customers — for a retail shop, it’s a small line item with outsized visual impact.
Why demand exists: Window cleaning is a recurring need, not a one-time purchase — dirt, hard water spots, and pollen accumulate regardless of season, and most people either don’t have the time, the ladder, or the interest in doing it themselves, especially above the first story.
How the industry changed heading into 2026: Two shifts stand out. First, water-fed pole systems using purified water have become the dominant method for exterior cleaning up to roughly three or four stories, replacing a lot of ladder work and reducing both labor time and liability exposure. Second, online booking and review-driven discovery (Google Business Profile, Nextdoor, Yelp) have replaced door-to-door flyering as the primary way small operators win new residential customers, which has lowered the marketing cost of entry but raised the importance of having a professional-looking online presence from day one.

4. Market Analysis (2026)
Estimated market size: The U.S. window cleaning services market is generally estimated in the low billions of dollars annually, spread across an enormous number of small, independent and owner-operator businesses rather than a handful of national chains. It’s a fragmented industry — most local markets are served by sole proprietors and small crews rather than large franchises.
Industry growth: Growth tends to track closely with residential real estate turnover, new commercial construction, and general consumer services spending — typically modest, low-single-digit annual growth in most metro areas, with faster growth in fast-developing suburban regions.
Demand drivers: New home sales, commercial real estate occupancy rates, seasonal pollen and storm activity, and a broader consumer trend toward outsourcing home maintenance tasks all support steady demand. Commercial demand is closely tied to foot-traffic-dependent retail — storefronts, restaurants, and car dealerships are reliable recurring clients.
Competition: Barriers to entry are low, which means most local markets have significant competition from other independents, plus a handful of regional franchise operators. Differentiation tends to come down to reliability, online reviews, and responsiveness rather than price alone — underpricing to win jobs is a common and risky beginner mistake, covered later in this guide.
Industry trends: Pure-water-fed pole systems, online booking software, and bundled service offerings (windows + gutters + pressure washing) are increasingly standard rather than optional for operators trying to differentiate and increase average ticket size.
Future outlook: The category is unlikely to see disruption from automation or software in the way many other services face — window cleaning remains fundamentally physical, on-site labor. That’s a structural advantage for small operators: this is not an easy business for a large tech platform to commoditize, but it also means growth is capped by labor availability rather than software leverage.
5. Startup Costs
Three realistic starting budgets, from bare-bones to commercial scale.
Budget 1: Bare Minimum (Solo, Traditional Tools)
| Item | Cost |
|---|---|
| Squeegees, applicators, scrapers | $150 |
| Extension ladder (24 ft) | $250 |
| Cleaning solution & microfiber cloths | $50 |
| Bucket, holster, basic tool belt | $60 |
| Business registration (sole prop/LLC filing) | $150 |
| General liability insurance (first quarter) | $300 |
| Basic website/booking page | $100 |
| Business cards & simple signage | $40 |
| Total | $1,100 |
Budget 2: Professional (Solo or Small Team, Water-Fed System)
| Item | Cost |
|---|---|
| Water-fed pole system + portable RO/DI filter | $1,200 |
| Extension ladders (2 sizes) | $500 |
| Full traditional tool kit (backup method) | $400 |
| Safety gear (harness, non-slip footwear) | $300 |
| Vehicle magnetic signage/wrap | $400 |
| Liability insurance (annual policy) | $900 |
| LLC formation + local licensing | $300 |
| Professional website + branding | $800 |
| Initial marketing (Google Business setup, local ads) | $500 |
| Uniforms/branded shirts | $150 |
| Total | $5,450 |
Budget 3: Commercial Scale (Van + Crew-Ready)
| Item | Cost |
|---|---|
| Used cargo van + wrap | $18,000 |
| Water-fed pole systems (2 setups) | $3,000 |
| Van-mounted pure water filtration system | $2,500 |
| High-reach/second-story safety equipment | $2,500 |
| Insurance (general liability + commercial auto) | $2,500 |
| Employee onboarding & safety training | $1,000 |
| Software (CRM, scheduling, invoicing) — annual | $600 |
| Marketing launch budget | $3,000 |
| Licensing & bonding | $500 |
| Total | $33,600 |
Recommended starting point: For most first-time owners, Budget 2 (Professional) offers the best balance — it’s enough to look and operate professionally, take on both residential and light commercial work, and still be recoverable within a few months if utilization is reasonable. Budget 1 is a viable test but limits both the jobs an operator can safely take (no water-fed reach) and the impression made on higher-value commercial clients. Budget 3 only makes sense once demand is already validated — buying a van and hiring before confirming there’s enough recurring work is one of the more common ways new operators overextend financially.
6. Monthly Operating Costs
| Expense | Solo Operator | Small Company | Growing Company |
|---|---|---|---|
| Rent | $0 | $300 | $800 |
| Insurance | $75 | $250 | $700 |
| Software | $30 | $80 | $250 |
| Utilities | $0 | $100 | $200 |
| Marketing | $150 | $500 | $1,500 |
| Payroll | $0 | $4,500 | $18,000 |
| Maintenance | $30 | $100 | $300 |
| Vehicle | $150 | $400 | $1,200 |
| Supplies | $60 | $200 | $500 |
| Repairs | $20 | $80 | $200 |
| Licensing | $10 | $30 | $60 |
| Electricity | $0 | $60 | $150 |
| Miscellaneous | $40 | $100 | $250 |
| Total Monthly Cost | $565 | $6,700 | $24,110 |
The single biggest cost jump between tiers is payroll — it’s the line item that separates a lifestyle solo business from a company. This is also why margins compress so sharply once employees are added; more on that in the profit margins section below.
7. Revenue Model
Pricing in window cleaning is almost always per-job, though structure varies by customer type.
Pricing: Residential jobs are typically priced per pane, per window, or as a flat rate for the whole house based on square footage and story count. For this guide, we use an assumption of $175 average revenue per residential job (a mid-size home, interior and exterior glass, screens and tracks included) — a reasonable mid-market figure, though actual pricing varies significantly by region and home size.
Billing methods: Most solo residential operators collect payment on completion (card readers, payment apps, or invoicing same-day). Commercial accounts are typically billed monthly on net-15 or net-30 terms.
Subscriptions/contracts: Commercial storefronts and office buildings frequently sign biweekly or monthly recurring contracts — these are the most valuable accounts in the business because they eliminate the need to re-sell the customer every visit. Residential customers are less likely to subscribe formally but often become repeat semi-annual customers once a good relationship is established.
Packages: Bundling windows with gutter cleaning, pressure washing, or solar panel cleaning is a common way to raise average order value without adding new customer acquisition cost.
Upsells: Screen cleaning, track and sill detailing, and hard water/mineral deposit removal are common add-ons priced separately from the base job.
Average transaction: ~$175 (residential), $250–$600+ (light commercial, per visit, depending on storefront size).
Minimum charge: Most operators set a minimum job charge ($100–$150 is common) to avoid small jobs being unprofitable once drive time and setup are factored in.
Recurring revenue: Commercial contracts are the closest thing this business has to predictable, recurring revenue, and are typically prioritized once an operator has enough residential volume to be selective.
8. Income Calculations
All figures use the $175 average residential job value and the monthly operating costs from Section 6. Tax is estimated at a flat 25% to account for combined self-employment and income tax exposure — actual rates vary by state and structure.
Scenario A: Part-Time Operator (15–20 hrs/week)
- Jobs completed: 3/week → 13/month (3 × 4.33 weeks)
- Monthly revenue: 13 × $175 = $2,275
- Annual revenue: $2,275 × 12 = $27,300
- Monthly operating cost (reduced marketing, part-time): $450
- Annual operating cost: $450 × 12 = $5,400
- Net profit before tax: $27,300 − $5,400 = $21,900
- Tax estimate (25%): $5,475
- Net profit after tax: $16,425
- Profit margin: $16,425 / $27,300 = 60.2%
Scenario B: Full-Time Owner-Operator
- Jobs completed: 6/week → 26/month
- Monthly revenue: 26 × $175 = $4,550
- Annual revenue: $4,550 × 12 = $54,600
- Monthly operating cost (Solo Operator tier, full marketing): $565
- Annual operating cost: $565 × 12 = $6,780
- Net profit before tax: $54,600 − $6,780 = $47,820
- Tax estimate (25%): $11,955
- Net profit after tax: $35,865
- Profit margin: $35,865 / $54,600 = 65.7%
Scenario C: Company with Employees (Owner + 2-Person Crew)
Assumes a mix of residential and light commercial work at a higher blended average of $200/job.
- Jobs completed: 12/week → 52/month
- Monthly revenue: 52 × $200 = $10,400
- Annual revenue: $10,400 × 12 = $124,800
- Monthly operating cost (Small Company tier): $6,700
- Annual operating cost: $6,700 × 12 = $80,400
- Net profit before tax: $124,800 − $80,400 = $44,400
- Tax estimate (25%): $11,100
- Net profit after tax: $33,300
- Profit margin: $33,300 / $124,800 = 26.7%
The pattern here is consistent with the broader risk and profit picture of adding staff: total revenue and total profit dollars go up substantially with a crew, but the profit margin drops sharply because payroll consumes a large share of each new dollar earned. Scenario C earns roughly double Scenario B in raw dollars but at less than half the margin.
9. Break-even Analysis
Using the Professional startup budget ($5,450) and Scenario B (Full-Time Owner-Operator) as the base case:
- Monthly fixed operating expenses: $565
- Revenue needed monthly just to cover overhead: $565 ÷ $175 per job = 3.2 jobs, rounded up to 4 jobs/month (roughly 1 job/week)
- At full-time capacity (26 jobs/month), that overhead break-even represents only about 15% utilization — meaning the business covers its basic monthly costs quickly, and the real question is how fast it fills the remaining 85% of capacity with paying work
- Monthly net profit before tax at full utilization: $47,820 ÷ 12 = $3,985/month
- Startup investment recovery: $5,450 ÷ $3,985 ≈ 1.4 months at full-time pace
- For a part-time operator (Scenario A), monthly net profit before tax is $21,900 ÷ 12 = $1,825/month, giving a recovery timeline of $5,450 ÷ $1,825 ≈ 3 months
- For the Commercial Scale budget ($33,600) paired with Scenario C’s monthly net profit before tax ($44,400 ÷ 12 = $3,700), recovery takes $33,600 ÷ $3,700 ≈ 9 months in a best-case ramp, though realistically 12–24 months once slower early ramp-up months are factored in
The takeaway: the equipment and licensing investment recovers quickly relative to most small businesses — the real break-even challenge is building a customer base fast enough to reach full utilization, not recouping the tools.
10. Profit Margins
- Gross margin: Direct material cost per job (soap, cloths, fuel allocation) is roughly $12–$18 per $175 job, putting gross margin around 90–93% — very high, because this is a labor-based service with minimal cost of goods.
- Operating margin (before tax): For a solo full-time operator, roughly 87–88% once overhead is deducted but before taxes — again reflecting how little fixed overhead a solo service business carries.
- Net margin (after tax): Roughly 60–66% for solo operators (Scenarios A and B), dropping to roughly 27% once payroll is introduced (Scenario C).
- Per-job profit: Approximately $115 net after-tax profit per $175 residential job for a solo full-time operator.
- Industry benchmark: Independent, low-overhead service contractors in cleaning-adjacent trades commonly run 50–70% net margins; once a business shifts to an employee-based model, margins in the 15–30% range are typical and consistent with what Scenario C shows here.
11. Daily Operations
Typical day: A solo operator’s day usually starts with route planning and equipment loading, followed by 3–6 scheduled jobs with drive time between them, and ends with invoicing, photo documentation for reviews/portfolio, and next-day prep.
Typical week: Weekdays are typically dedicated to jobs and quoting, while weekends (for solo/part-time operators) often serve as overflow capacity or the primary working window for those still transitioning from other employment.
Customer workflow: Inquiry → quote (often via photos or a quick video call) → scheduling → service → payment → review request → follow-up scheduling for the next seasonal visit.
Scheduling: Route density matters a lot — clustering jobs geographically by day reduces drive time and fuel cost significantly compared to scattering appointments across a wide service area.
Equipment preparation: Water tank refills (for water-fed systems), ladder and safety gear checks, and vehicle loading typically take 15–30 minutes each morning.
Maintenance: Weekly equipment checks (squeegee rubber replacement, hose inspection, filter checks on water systems) prevent mid-job equipment failures.
Seasonality: Spring (post-pollen) and fall (pre-winter) are the busiest windows for residential work; commercial contract work tends to stay more consistent year-round. Winter in colder climates typically slows residential demand significantly, which is why many operators add gutter cleaning or holiday lighting installation as a seasonal revenue supplement.

12. Equipment & Software
Equipment
- Water-fed pole system with purified (deionized) water — the modern standard for exterior work up to 3–4 stories, reducing streaking and eliminating the need for chemical runoff
- Traditional squeegees, scrapers, and applicators — still necessary for interior work and detail cleaning
- Extension ladders — for lower-reach exterior work and situations where a water-fed pole isn’t practical
- Safety harnesses and fall-protection gear for any second-story-plus ladder work
- A dedicated vehicle, ideally wrapped or signed for local brand visibility
Software
- CRM/scheduling: Manages recurring commercial contracts and residential seasonal reminders — critical for retention once the customer base grows beyond what a paper calendar can handle
- Accounting: Basic bookkeeping software for tracking job-level profitability, mileage, and tax prep
- Scheduling/routing: Route optimization tools reduce drive time between jobs, directly protecting margin
- Marketing: Google Business Profile management and review-request automation tools drive most new residential leads in this industry
- Industry-specific platforms: Field service management platforms built for home service businesses (quoting, invoicing, and dispatch in one system) become worthwhile once a business has more than one crew
13. Risks & Failure Points
Pricing pressure. Because barriers to entry are low, new competitors enter constantly, and some price aggressively to win early customers. Operators who compete purely on price rather than reliability and quality tend to erode their own margins over time, since low prices attract price-sensitive customers who churn easily when an even cheaper competitor appears.
Competition from established players. Long-running local operators often have decades of accumulated reviews, referral networks, and recurring commercial contracts that are difficult for a new entrant to displace quickly. Winning commercial accounts in particular often requires underbidding an incumbent or waiting for a service failure to create an opening.
Economic downturn sensitivity. Residential window cleaning is a discretionary expense — during a downturn, many homeowners will defer or eliminate it before cutting essential expenses. Commercial contracts tend to be somewhat stickier but are not immune, particularly if retail tenants close or reduce their own operating budgets.
Equipment failure. A broken water pump, a cracked pole section, or a failed filtration system can take a solo operator out of commission for a day or more if a backup isn’t available, directly costing scheduled revenue. Commercial-scale operations mitigate this with redundant equipment, which adds to the capital requirement.
Legal and liability risk. Ladder work and second-story access carry real injury risk, both to the operator and, in rare cases, to property (broken glass, water damage from an equipment malfunction). Adequate general liability insurance is not optional — a single uninsured incident can financially end a small operation. Fall-related injuries are a well-documented hazard across cleaning and maintenance occupations that involve ladder use, which is why following OSHA’s ladder safety standards matters even for a one-person operation.
Customer acquisition cost creep. Early customers often come from personal networks and low-cost channels, but sustained growth typically requires paid advertising, and the cost per acquired customer tends to rise as easy, organic leads are exhausted — squeezing margins for operators who haven’t built a strong referral or recurring-contract base.
Industry-specific weather risk. Rain, high winds, and freezing temperatures directly prevent exterior work, creating unpredictable gaps in the schedule that a purely per-job revenue model doesn’t smooth out the way a subscription-based service would.
Cash flow timing. Residential jobs are typically paid immediately, but commercial contracts on net-30 terms can create a lag between completing work and receiving payment — a real strain once payroll has to be met before invoices are collected.
Employee-related issues. Once a business hires, no-shows, turnover, and the physical demands of the job (which lead to higher-than-average injury and burnout rates in cleaning-adjacent trades) become recurring operational headaches, and finding reliable crew members willing to do physically demanding, weather-exposed work at the wages this business can typically afford is a persistent challenge.
14. Step-by-Step Startup Guide
- Research the local market. Identify how many competitors already operate in the target area, what they charge, and whether commercial storefronts in the area currently outsource window cleaning or handle it in-house.
- Choose a business structure and register. Most operators start as an LLC for liability protection; registration requirements vary by state, so checking SBA guidance on registering a business is a reasonable first step before filing.
- Secure general liability insurance. This should happen before the first paid job, not after — a single accident without coverage can be financially catastrophic for a new business.
- Buy starter equipment. Choose between Budget 1 and Budget 2 from Section 5 based on available capital and whether water-fed systems are needed for the target customer mix.
- Set pricing and service packages. Decide on per-job vs. per-window pricing, minimum charges, and any bundled packages (screens, tracks, gutters) before marketing begins.
- Build a basic online presence. A Google Business Profile, a simple website, and a way to collect online reviews are the minimum viable marketing infrastructure for this business in 2026.
- Land the first 10–20 customers. Early customers typically come from personal networks, neighborhood social apps, and direct outreach to small commercial storefronts — cold, in-person commercial pitches still work well for this trade.
- Systemize scheduling and follow-up. Set up recurring seasonal reminders for residential customers and formal contract terms for commercial accounts to convert one-time jobs into repeat revenue.
- Track job-level profitability. Once volume increases, review which job types and customer segments are actually most profitable per hour worked, not just per job.
- Scale deliberately. Add a second technician or a van-based setup only once demand consistently exceeds solo capacity — hiring ahead of demand is one of the most common ways new operators strain cash flow.
15. Expansion Opportunities
Upsells: Screen cleaning, track and sill detailing, and hard water stain removal add revenue per visit with minimal additional time.
Additional services: Gutter cleaning, pressure washing, solar panel cleaning, and holiday lighting installation are natural adjacent services that use overlapping equipment and smooth out seasonal revenue gaps.
New locations: Expanding into a neighboring service area is often more capital-efficient than deepening penetration in an already-saturated territory.
Recurring revenue: Prioritizing commercial contracts over one-off residential jobs builds a more predictable revenue base and reduces the month-to-month volatility inherent in a purely per-job model.
Commercial contracts: Larger office parks, retail chains, and property management companies with multiple buildings represent the highest-value account type — a single contract can replace dozens of individual residential jobs in monthly revenue.
Franchising: Once a single-location operation has a proven, documented system, some owners license or franchise the model to other territories, though this is a longer-term path relevant mainly to operators who’ve already scaled past the “growing company” stage described in this guide.
16. Common Beginner Mistakes
- Underpricing to win early jobs. New operators often price below market to build a customer base, then struggle to raise prices later without losing price-sensitive customers.
- Skipping liability insurance. Some beginners delay insurance to save money early — a single accident can cost far more than years of premiums.
- Buying commercial-scale equipment too early. Purchasing a van and hiring staff before demand is validated strains cash flow unnecessarily.
- Underestimating drive time. Failing to cluster jobs geographically eats into billable hours and fuel costs.
- Ignoring recurring/commercial accounts. Focusing only on one-off residential jobs leaves revenue unpredictable month to month.
- Poor online presence. In 2026, a business without a Google Business Profile and visible reviews loses a significant share of potential leads to competitors who have both.
- No systemized follow-up. Failing to schedule seasonal reminders for residential customers means losing repeat business to whichever competitor happens to reach the customer first the following season.
- Underestimating weather-related downtime. New operators often build financial plans assuming every scheduled day is workable, without buffering for rained-out or wind-cancelled days.
- Hiring too fast. Adding employees before there’s consistent job volume to keep them busy turns a profitable solo operation into a cash-flow-negative one.
- Neglecting equipment maintenance. Deferred maintenance on water-fed systems and ladders leads to mid-job failures that cost same-day revenue and damage customer trust.

18. FAQs
How much does it cost to start a window cleaning business? Startup costs range from about $1,100 for a bare-minimum solo setup with traditional tools to roughly $5,450 for a professional water-fed system setup, up to around $33,600 for a van-based commercial operation ready to hire employees.
Is a window cleaning business profitable? Yes — solo operators commonly see net profit margins of 60–66% after tax due to low overhead, while employee-based operations typically run 25–30% margins once payroll is factored in.
How much can a window cleaner make per month? A part-time solo operator might net around $1,370/month after tax, while a full-time solo operator can net roughly $2,990/month, based on the calculations shown in this guide’s income scenarios.
Do I need a license to start a window cleaning business? Requirements vary by state and locality; most operators need at minimum a business registration (LLC or sole proprietorship) and general liability insurance, and some cities require a local business license.
What equipment do I need to start? At minimum: squeegees, applicators, buckets, cleaning solution, and a ladder. A water-fed pole system with purified water is increasingly standard for exterior work and improves both efficiency and safety.
Is window cleaning dangerous? Ladder work and second-story access carry genuine fall risk, which is why general liability insurance and proper safety equipment are essential rather than optional, especially for jobs above one story.
How do I get my first customers? Most new operators start with personal networks, neighborhood apps like Nextdoor, and direct in-person outreach to small commercial storefronts, combined with setting up a Google Business Profile from day one.
Should I focus on residential or commercial clients? Residential work is easier to win early on, but commercial contracts provide more predictable, recurring revenue and are generally worth prioritizing once the business has enough of a track record to compete for them.
How long does it take to break even? For a solo operator using the Professional startup budget, break-even on the initial equipment investment typically takes 1–3 months at full-time pace; for a van-based commercial setup, realistic break-even is closer to 12–24 months.
Can this business scale into a full company? Yes — window cleaning scales reasonably well by adding crews and vehicles, though margins compress meaningfully once payroll is introduced, so scaling should be paced to actual demand rather than done preemptively.
19. BusinessDiscovered Verdict
Works Best For
- People comfortable with physical, outdoor, weather-exposed work
- Those who want a low-capital way to test entrepreneurship before committing to a larger investment
- Operators willing to build a genuine local reputation and online review base rather than compete purely on price
- Anyone looking for a business with fast break-even potential relative to the initial investment
Not Ideal For
- Those seeking a passive or low-touch income stream — this remains a hands-on labor business even at the company stage
- People uncomfortable with height-related work or unwilling to invest properly in safety equipment and insurance
- Anyone expecting rapid, software-style scaling — growth here is bounded by hiring and route density, not virality
- Those unwilling to compete on service quality and reviews in an already-crowded, low-barrier local market

Honest assessment: A window cleaning business is a legitimately accessible way to generate solid margins with modest starting capital, and the math in this guide backs that up — a full-time solo operator can realistically clear over $35,000 a year after tax on a $5,450 initial investment. But the business doesn’t get dramatically more profitable on a margin basis as it scales; it gets more profitable in absolute dollars while margins compress due to payroll. Anyone going in should be honest with themselves about whether they’re building a well-paying solo trade or a genuine company, since those are different goals requiring different startup budgets and different tolerance for the operational and staffing risks that come with hiring.

Additional Reference: According to the U.S. Bureau of Labor Statistics, building and grounds cleaning work — the broader occupational category window washing falls under — pays a median wage that’s notably below the all-occupation median, underscoring why controlling labor cost is central to profitability once a window cleaning business moves from solo operator to employer (see the BLS Occupational Outlook Handbook entry for janitors and building cleaners). For general background on the trade itself, see the Wikipedia overview of window cleaning.
