Every solo window cleaner who has made it past year one has some version of the same story: a rough first job, a pricing mistake that stung, and a slow, unglamorous climb from knocking on doors to a business that runs itself. None of it is a secret. It is just scattered.
This guide pulls the whole path together: whether it is worth starting, what it actually costs, the legal basics nobody explains clearly, how to price the work, how to get your first clients without a marketing budget, and when you actually need help. Each stage below is a summary, and the deep dive for each one links out as its own guide.
You do not need to finish every stage before you take a job. Stages 1 to 3 get you ready to work. Stage 4 makes sure the work is priced properly. Stages 5 to 7 build a business that grows without you knocking on every door. Read it once end to end, then come back to each stage when you are ready for it.
Step 1, Is window cleaning a good business to start?
It is one of the more accessible trades to get into. The core skill is learnable in weeks rather than years, the equipment cost is low compared to most trades, and it is genuinely flexible. The overwhelming majority of people who start doing this begin as a side hustle around a full-time job, not as a leap of faith.
The honest tradeoffs: it is physically demanding, with heights, heat and repetitive ladder work, it is seasonal in colder climates, and the first year is slow no matter how good you are at the actual cleaning. Real trajectories from operators who have been through it vary widely. Some reach roughly $15,000 in recurring annual revenue within a year working weekends only, without quitting the day job. Others report closer to $50,000 in their first full year. A handful of experienced solo operators several years in describe clearing around six figures, but that is after multiple years of consistent work, not month one.
The pattern that shows up again and again: the first one to three years are the hardest part of any service business, not something specific to window cleaning. The people who stuck with it past the rough first few months are the ones who ended up glad they started.

You do not need an LLC to start. Most solo operators begin as a sole proprietor, with business revenue flowing through their personal tax return. An LLC can come later, once there is a real business, and real assets, to protect.
Insurance is a different story, and contractors who have actually done the work treat it as close to non-negotiable. The risk is real and recurring: a broken pane, a damaged screen, a dispute over pre-existing hard water etching you did not cause. A basic liability policy is commonly cited at around $40 per month, and some states legally require coverage to operate at all, so it is worth checking your own state's requirements before your first paid job.
Two more habits worth building from day one. Open a dedicated business bank account so personal and business money never mix, which makes taxes and bookkeeping dramatically simpler. And get in the habit of a fast pre-job walkthrough, checking for existing damage and photographing anything questionable before you start. It is the cheapest insurance there is against a dispute over damage you did not cause.

The starter kit that comes up over and over, across operators with wildly different backgrounds, is short: a squeegee with channel and rubber, a scrubber or applicator sleeve, a bucket, an A-frame ladder, microfiber cloths or surgical towels, basic dish soap, and a bit of 0000 steel wool for stuck-on residue. That is genuinely enough to start, a few hundred dollars covers it, and some operators book their first job before buying anything, then put the gear on a card and pay it off with that first payment.
Two well-regarded, affordable brands come up consistently among people who have actually worn out a few squeegees: Ettore and Unger. A basic hardware-store squeegee works fine to learn on, but most operators upgrade fairly quickly.
Worth the extra $20
A compressed-air duster, the kind sold for cleaning electronics, plus a stiff track brush makes exterior track cleaning dramatically faster than scraping by hand. Wear eye protection, because it kicks debris straight back at you.
One area trips up almost everyone on their first few jobs: screens. They take longer than expected, springs can be fragile, and screens that look interchangeable often are not, so mixing them up between windows on the same house is a near-universal rookie mistake. The fix that saves the most time is reinstalling each screen right after you clean that window, instead of pulling every screen in the house first and sorting them out later.

Pricing is where new operators lose the most money without realising it. One operator's very first paid job, a two-story hundred-year-old home with real French panes and storm windows nobody warned them about, took two full 12-hour days and was billed at a flat $200. That works out to about $8 an hour before gas, gear wear, or the screens that had to be replaced. It is an extreme case, but a mild version of it happens to almost everyone who prices from a gut feeling instead of a framework.
The short version: price per window based on scope, interior, exterior or both, add a story-height premium for anything above ground level, and price screens, tracks, storm windows and hard water treatment as their own line items instead of folding them into the base rate.

There are two legitimate starting points, and neither is wrong. Some operators spend a season working for an established window cleaning company first, learning technique and the business side, quoting, routing, customer service, while getting paid, with none of the pressure of finding their own customers yet. Others build their own base from day one.
If you are going solo immediately, door-to-door is the fastest and cheapest way to get initial momentum, even among people who genuinely dislike doing it. The pattern: sell one job in a neighbourhood, then use it as leverage, with door hangers, a yard sign or a referral ask, to pick up the rest of the street. It does not have to be permanent. A common approach is knocking enough early on to build a real portfolio of before-and-after photos and reviews, then shifting weight toward online and referral channels once those channels have something to work with.
- Google Business Profile, worth setting up before you even have a website
- Nextdoor, where one operator traced roughly half their revenue back to a single post
- Google Local Service Ads and Thumbtack, both solid and targeted once you are ready to pay for leads
- The referral ask, one neighbour referral requested from every happy customer before you leave the job
- Fast follow-up, a same-day or next-morning text to quotes that did not convert, which closes more jobs than people expect
Step 6, Business software: what you actually need
Early on, most solo operators get by on almost nothing. Cash, Venmo or Zelle for payment, and quotes tracked in a text thread or a notebook. That is genuinely fine at low volume.
The gaps start to show as the business grows: quotes scattered across texts instead of living in one place, no clean invoice trail, no easy way to tell a recurring seasonal client from a one-time job. That is the point where dedicated field service software starts paying for itself, with quotes and e-signature, invoicing and payment in one place rather than a spreadsheet stitched to three different apps.

The signal shows up across almost every operator who has scaled past solo: growth stalls at the point where your own two hands become the bottleneck, not demand. If you are consistently turning away work or pushing new bookings out further than you are comfortable with, that is the tell, not a specific revenue number.
The first hire does not have to be a full-time employee. A common bridge is part-time help for the physical labour, the actual window cleaning, while you shift more of your own time toward quoting, sales and running the business.

Frequently asked questions
How much does it cost to start a window cleaning business?
A basic starter kit, squeegee, applicator, bucket, A-frame ladder, cloths and soap, typically runs a few hundred dollars. Add roughly $40 per month for basic liability insurance. Water-fed pole systems, extension ladders and vans are common upgrades once you have steady customers, not day-one requirements.
Do I need a license to start a window cleaning business?
Most places let you start as a sole proprietor with no special license, though liability insurance is close to a must-have and some states legally require it. Check your own state and city requirements before your first paid job.
Is window cleaning a good business to start with no experience?
It is one of the more accessible trades to start. The core skill is learnable in weeks rather than years, and the equipment cost is low compared to most trades. The tradeoff is a genuinely rough first few jobs while you learn technique, pricing and screens, and an income that builds slowly over the first year.
Should I work for a window cleaning company before starting my own?
Many successful solo operators started this way. A season working for an established company teaches technique and the business side, quoting, routing and customer service, while you are getting paid, without the pressure of finding your own customers yet. It is not required, but it is a common and low-risk way in.
How do I price my first few window cleaning jobs?
Price per window by scope rather than per hour, apply a story-height multiplier above ground level, and put screens, tracks, storm windows and hard water treatment on the quote as separate lines. The pricing framework walks through the whole method, and the free estimator does the arithmetic.
