People who want a very low-cost start and the chance to build short, frequent recurring storefront routes alongside higher-ticket residential jobs
A fall from a ladder or roof — the leading cause of serious injury in this trade — or skipping insurance and facing a broken-window or water-damage claim
Ranges reflect realistic outcomes across reported data — not best-case promises. See the full earnings breakdown below.
What this business actually is
A window cleaning business cleans glass for two distinct markets: residential homes (interior and exterior windows, screens, tracks, and sometimes skylights or French panes) and commercial storefronts (the street-facing glass that shops want spotless). The two markets behave very differently. Residential jobs are higher-ticket and seasonal, while storefront work is small per visit ($10 to $50 a stop) but extremely frequent — many storefronts want their glass cleaned weekly or monthly, creating tight recurring routes you can run in an hour or two. Equipment costs are among the lowest of any service trade; a beginner can start with a few hundred dollars of squeegees, a bucket, and a pole.
What you actually do — the daily reality
A residential day means one to three homes, where you work through interior and exterior glass with a squeegee and scrubber, wipe edges, clean tracks, and reinstall screens — anywhere from one to four hours per home depending on the number of panes. A storefront route day is the opposite: you drive a tight loop hitting 10 to 30 small businesses, spending five to twenty minutes each, building a rhythm. You are on your feet, often on ladders, and outdoors in changing weather. Around the work, expect quoting, collecting from storefronts, and scheduling. Streak-free results in real sunlight and wind are the skill that separates a pro from an amateur.

Real earnings — an honest breakdown
Not best-case fantasies. Here is what beginners, experienced operators, and the top earners actually report — and what it took to get there.
Part-time beginners commonly earn $1,500 to $3,500 per month while learning to work fast and building a route. A solo cleaner who goes full-time and mixes residential jobs with a storefront route typically reaches $3,500 to $6,000 per month once booked consistently.
Experienced solo operators with a dense storefront route and steady residential work often report $5,000 to $9,000 per month. The recurring storefront accounts provide a stable weekly base, while residential and post-construction jobs add the higher-ticket spikes.
Multi-crew window cleaning companies, often adding pressure washing and gutter services, gross $20,000 to $80,000+ per month, but reaching that requires hiring, training crews to deliver streak-free results, equipment for high and commercial glass, real marketing, and a shift to managing rather than cleaning. Most operators stay solo or run a single small crew.
Solo operators commonly net $40 to $90 per hour of actual cleaning once efficient, with dense storefront routes and high-pane residential jobs at the upper end. Counting driving, quoting, and collections, realistic blended rates often land at $30 to $65 per hour.
Speed and route density matter most. Storefront profit comes entirely from how many stops you can chain together in a tight loop, and residential profit comes from cleaning panes fast and streak-free. A beginner and a pro can charge similar prices but earn double the hourly rate purely on technique and routing.
How to actually start — step by step
- Week 1
Buy professional squeegees, a scrubber, channels, and a pole — skip consumer spray-and-wipe gear. Practice the squeegee fan and straight-pull techniques on your own windows until you can finish glass streak-free in sun and wind. Get general liability insurance before paid work.
- Week 2
Set pricing — per pane or per window for residential, flat per-visit for storefronts. Walk a commercial strip and pitch storefront owners on a recurring weekly or monthly clean; small recurring stops are easier first wins than large homes.
- Month 1
Build your first storefront route as a tight geographic loop you can run in an hour or two, and complete your first residential jobs. Ask residential clients for Google reviews and ask storefronts to refer neighboring businesses on the same block.
- Days 30-90
Densify the route by adding businesses near existing stops, lock storefronts into fixed visit frequencies, and decide whether to add a water-fed pole for high exterior glass. Track time per job to learn your true hourly rate and price up as you get faster.
- Months 3-6
Add complementary services like screen repair, track cleaning, or pressure washing to raise per-visit revenue, and consider a helper if residential demand exceeds your solo capacity.
What skills you actually need
Skills you must have before starting
- Steady hands and patience to deliver consistently streak-free glass
- Comfort working on ladders and at height with a real awareness of fall safety
- Willingness to walk in and pitch storefront owners face to face for recurring work
Skills you can learn as you go
- Squeegee technique — the fan and straight-pull methods that make a pro fast and streak-free
- Working glass in direct sun and wind without leaving spots
- Cleaning tracks, screens, and divided-light panes efficiently
What separates average operators from high earners
- Building a dense storefront route so recurring small jobs chain into a profitable day
- Working fast enough that your effective hourly rate doubles versus a beginner at the same prices
- Selling recurring storefront contracts and higher-value residential add-ons confidently
What most people get wrong
The common mistakes, the reasons people quit, and the things nobody warns you about.
- Using consumer spray cleaner and paper towels instead of learning the squeegee, leaving streaks that lose clients
- Underpricing storefronts so a route that takes hours barely clears minimum wage after driving
- Taking scattered storefront accounts that never chain into a tight route, so drive time eats the profit
- Ignoring ladder and fall safety, which is the leading cause of serious injury in this trade
- Skipping insurance, then facing a broken-window or interior water-damage claim that wipes out months of income
- Quoting high residential jobs before they can finish glass cleanly and quickly, leading to callbacks and refunds
Tools and equipment you need
What to buy cheap, where to invest, and what you can rent or borrow at first.
- Professional squeegee with interchangeable channels $30 – $150
The core tool. Pro brands (Unger, Ettore, Moerman) and a quality rubber make streak-free work possible.
- Scrubber/washer sleeves and an applicator $20 – $80
Loosens dirt before the squeegee pass. Multiple sleeves let you swap dirty for clean on the route.
- Extension pole $40 – $250
Reaches second-story and high storefront glass from the ground, reducing ladder time and risk.
- Ladder $100 – $400
Needed for many residential exteriors. Buy a sturdy one and learn safe setup; falls are the real danger here.
- Water-fed pole and pure-water system Free – $1,500
Cleans high exterior glass from the ground with deionized water, no streaks, no ladder. A scaling investment.
- Microfiber towels, scrapers, and a tool belt $30 – $120
For detailing edges, removing paint or stickers, and keeping tools handy on a route.
How to find customers
What actually works:
- Walking commercial strips and pitching storefront owners directly on recurring weekly or monthly cleans
- A complete Google Business Profile with before/after photos and reviews for residential search traffic
- Local Facebook and Nextdoor groups where homeowners ask for window cleaner recommendations, especially in spring
- Asking storefronts to refer neighboring businesses on the same block to densify your route
- Partnering with house cleaners, pressure washers, and realtors for residential referrals
Where your customers are: Storefront customers are small retail, restaurants, salons, and offices on commercial strips wanting visible street-facing glass kept clean. Residential customers are homeowners in suburban neighborhoods, with demand spiking in spring and before holidays.
How long it takes to build a client base: Storefront accounts can be landed within days by walking a strip and pitching, since the per-visit cost is low and the decision is fast. A full residential and recurring storefront book usually takes two to five months to build into a reliably busy schedule.
What is usually a waste of time: Paid online ads and a polished brand before you have reviews and a route. Early on, walking storefronts in person and collecting residential reviews convert far better than advertising spend.
How this business scales
Can you grow it to full-time? Yes. A solo operator can reach full-time income by combining a dense recurring storefront route with residential jobs, often within the first year. The solo ceiling is set by hours and how fast you can clean, and cold-climate winters slow residential exterior work.
Can you hire people and step back? Possible but requires training crews to deliver consistently streak-free results, which is harder than it looks. Hiring lets you run more routes and bigger commercial buildings, but quality control is the constant challenge. Stepping back needs documented standards and a reliable lead.
Can you sell it one day? Yes — a window cleaning business with documented recurring storefront contracts and a residential client list sells, because the buyer gets predictable route revenue. A purely residential, owner-dependent operation with no recurring accounts is harder to transfer.
What scaling actually requires: A dense base of recurring storefront and commercial accounts, standardized pricing and cleaning standards, equipment for high and commercial glass, trained crews who deliver streak-free results, and routing software. Many operators add pressure washing and gutter cleaning to raise revenue per stop.
Is this right for you? An honest checklist
A strong fit if…
- You want the lowest possible startup cost among service trades
- You are comfortable on ladders and serious about fall safety
- You enjoy detailed, results-driven work where the finish is visibly perfect
- You are willing to walk in and pitch storefront owners for recurring contracts
A poor fit if…
- You are afraid of heights or unwilling to work safely on ladders
- You lack the patience to deliver consistently streak-free glass
- You are uncomfortable selling recurring contracts in person
- You depend on steady year-round residential income in a cold climate with no commercial route
Before you start, ask yourself…
- Am I comfortable working safely at height, knowing falls are the main risk in this trade?
- Will I put in the practice to clean glass streak-free and fast before charging full prices?
- Is there enough commercial density nearby to build a tight, profitable storefront route?
Frequently asked questions
Do I need a license to start a window cleaning business?
Most areas require only a general business registration, not a specific window cleaning license. However, general liability insurance is effectively essential because broken windows and interior water damage are real risks, and most commercial clients require proof of insurance before hiring you. High-rise or rope-access window cleaning is a different, heavily regulated specialty with strict OSHA requirements.
How much should I charge for window cleaning?
Residential is commonly priced per pane (roughly $4 to $10 in and out) or per window, with screen and track cleaning as add-ons; a typical home runs $150 to $400. Storefronts are flat per visit, often $10 to $50 depending on glass count. The key is pricing storefronts so a full route stays profitable after driving between stops.
Why is storefront work worth so little per stop?
Each storefront visit is small, but the value is frequency and density — many businesses want weekly or monthly service, and a tight route of 15 to 30 stops you can run in an hour or two adds up to dependable recurring revenue. The profit is entirely in routing: scattered storefronts lose money, while a clustered loop is some of the most reliable income in the trade.
How do I get streak-free windows in direct sunlight?
Sun and wind dry the glass before you can finish, leaving streaks. Pros work shaded sides first, clean early or on overcast days when possible, use less soap, and master a fast squeegee fan so the glass is squeegeed before it dries. It takes real practice; this technique is what separates a professional finish from an amateur one.
Is window cleaning dangerous?
The main danger is falls from ladders and roofs, which cause the most serious injuries in this trade. Learn proper ladder setup, never overreach, use an extension or water-fed pole to clean high glass from the ground, and avoid working in wind. A water-fed pole system reduces ladder time significantly and is worth the investment as you take on taller exterior work.
Do I need a water-fed pole system to start?
No. You can start with squeegees, a bucket, a pole, and a ladder for a few hundred dollars and handle most ground-floor and second-story glass. A water-fed pole with pure water lets you clean high exterior glass from the ground without streaks or ladders, but it is a scaling investment to add once you take on taller or commercial buildings.
How quickly can I start making money?
Storefront accounts can be landed within days because the per-visit cost is low and owners decide fast. Residential jobs typically come within one to two weeks of marketing. Building a full route and a reliable book usually takes two to five months of consistent work, reviews, and route-densifying referrals.
