How to Start a Window Cleaning Business
A window cleaning business needs little more than good tools, a safe way of working and a round of loyal customers. Spring is when homeowners and shops notice the winter grime on their glass, so the end of February is a smart moment to get set up and start knocking on doors.
Key takeaways
- Choose your niche early: homes, shopfronts or low-rise commercial buildings each need different tools and pricing.
- Working at height is the biggest risk. The UK Work at Height Regulations 2005 apply, and in the US, OSHA fall protection rules apply.
- Recurring rounds every few weeks are what turn window cleaning into a steady income.
- Price per property or per window, and build tight routes so you spend your day cleaning, not driving.
Window cleaning has a lot going for it as a small business. Startup costs are modest, the work is visible (customers can see the result instantly), and most clients want the service repeated every four to eight weeks. Build a round of a few dozen regular houses and shops and you have predictable income that does not depend on constant selling.
This guide covers the practical steps: choosing your services, staying safe and legal, getting the right kit, pricing your work and finding customers. It is general information, not legal, tax or insurance advice. Rules vary by country, state and city, so check with official sources and talk to a qualified accountant or insurance broker about your own situation.
Choose your window cleaning niche
Not all window cleaning is the same job. Your niche decides your equipment, your safety plan and your prices, so it is worth thinking about before you spend anything.
Residential rounds
Houses and apartments on the ground and first floors. This is where most owners start. Jobs are short, customers are friendly, and you can fit many homes on one street into a morning. The main selling points are reliability and a clean, streak-free finish.
Shopfronts and small commercial
Cafes, salons, offices and retail units often want their glass cleaned weekly or every two weeks, sometimes early in the morning before opening. These clients value consistency and simple invoicing, and a single high street can give you a dense round.
Specialist and add-on work
Once you are established, you can add conservatory roofs, skylights, gutter clearing, fascia and soffit cleaning, solar panel cleaning or post-construction cleans. These pay more per job but often need extra training, equipment or insurance. Higher-rise buildings that need rope access or powered platforms are a specialist field and are best left until you have proper training and experience.
Pro tip
Start with one niche and one area. A round of 40 houses within a short drive of each other will earn you more per hour than 40 scattered jobs across a city, and your customers will see your van in their street every week.
Safety first: working at height
Falls from height are a serious risk in window cleaning, and safety is not something to improvise. Plan how you will reach every window before you quote, and walk away from any job you cannot do safely with your current kit.
The rules in the UK and US
In the UK, the Work at Height Regulations 2005 apply to window cleaning. In general terms, they expect you to avoid working at height where you reasonably can, use suitable equipment to prevent falls where you cannot avoid it, and plan and supervise the work properly. Many window cleaners use water-fed poles so they can clean upper windows from the ground.
In the US, OSHA fall protection rules apply to work at height, and employers also have duties under OSHA's general duty clause to keep the workplace free of recognized hazards. Ladder use, anchors and harnesses all come with specific requirements, so read the guidance on OSHA's website and consider formal training before working above ground level.
If you employ people in the UK, the Health and Safety at Work Act applies, and employers with 5 or more employees must have a written health and safety policy and a written risk assessment. Even as a solo operator, writing a short risk assessment for each type of job is a smart habit.
Common mistake
Saying yes to a tricky upper window "just this once" with a borrowed ladder on uneven ground. One fall can end your business. If you cannot reach a window safely with a water-fed pole or properly set up equipment, tell the customer you cannot clean it yet, and explain why. Most will respect the honesty.
Set up the business properly
A little admin now saves stress later. The common startup steps are choosing a business structure, registering, checking licenses and permits (which vary by location), getting insurance, setting your prices, and putting a booking and invoicing setup in place.
- Structure. Many window cleaners start as a sole proprietor in the US or a sole trader in the UK. An LLC or limited company may suit you later. Ask an accountant which fits your situation.
- Registration and licenses. Register with your tax authority and check whether your city, county or local council requires a business license or permit for working on public footpaths.
- Insurance. Public or general liability insurance is the usual starting point, covering accidental damage to property or injury to the public. Check that your vehicle insurance covers business use. If you hire staff, look into employers' liability insurance in the UK, where it is generally required, or workers' compensation in the US.
- Bank account. Keep business money separate from day one. It makes tax time far easier.
Some local councils or business districts also have rules about water run-off on pavements or working hours near shops, so ask before you start a commercial round.
Get the right equipment
You can start window cleaning with a modest kit and add more as your round grows. Buy quality where it touches the glass or keeps you safe, and save money elsewhere.
Traditional kit
- Squeegees in a few widths, plus spare rubber blades
- Applicators (often called washers or strip washers)
- Scrapers for stubborn marks, used carefully
- Microfiber cloths and scrim for detailing edges
- A bucket, a tool belt and a suitable cleaning solution
Water-fed pole system
A water-fed pole system pumps purified water through a long pole to a soft brush, letting you clean upper windows from the ground. It usually needs a water purification unit and either a van-mounted tank or a trolley system. It costs more up front but can make your work safer and faster on many houses. Research the options, talk to other window cleaners and check current features and pricing before you buy.
Transport and safety gear
You will need a vehicle that can carry poles and water, plus non-slip footwear, gloves, high-visibility clothing for roadside work and a basic first aid kit. If you plan to use ladders at all, buy proper commercial-grade ones and learn how to inspect them before each use.
Price your window cleaning work
Good pricing starts with your costs and your time. Add up your monthly running costs, including fuel, insurance, equipment wear, phone, software and marketing. Add the pay you want for yourself and a profit margin. Divide by the hours you can realistically clean each month, and you have a target hourly rate to check every quote against.
Common pricing approaches
- Per property. A set price for a house based on its size and number of windows. Simple for homeowners.
- Per window or per pane. Useful for larger or unusual buildings, and easy to explain on a quote.
- Per visit for commercial clients. A fixed price for each scheduled clean, often invoiced monthly.
- Extras. Inside windows, frames and sills, conservatory roofs and first-time cleans priced separately.
First cleans usually take longer than regular ones because of built-up dirt. Many window cleaners charge more for the first visit and explain that the regular price will be lower once the glass is maintained.
A round planning template
Use this table to plan your round and check each customer's value. All amounts are made-up examples for illustration only.
| Customer | Type | Frequency | Minutes on site | Price per clean (example) | Cleans per year | Yearly value (example) |
|---|---|---|---|---|---|---|
| 14 Rose Lane | Semi-detached house, outside only | Every 4 weeks | 20 | £20 | 13 | £260 |
| The Corner Cafe | Shopfront, inside and out | Weekly | 25 | £18 | 52 | £936 |
| 3 Hill View | Detached house with conservatory | Every 8 weeks | 45 | £40 | 6 or 7 | £240 to £280 |
Add a column for travel time between stops. Customers who are far from the rest of your round may need a higher price or a different day.
Hypothetical example
Imagine Aisha, who starts a window cleaning business in her town with a water-fed pole and a small van. She canvasses three neighboring streets in March, offering a discounted first clean to anyone who signs up for a regular four-weekly service. By the end of spring she has 45 houses and two cafes on her round, mostly within walking distance of each other. Because her stops are so close, she can clean around 20 houses on a good day and still finish by mid-afternoon.
Find customers and build your round
Window cleaning is a door-to-door business at heart. The fastest way to build a round is to fill the streets you already work on.
- Pick target streets. Choose a handful of neighborhoods with plenty of homes that suit your kit.
- Canvass in person. Knock on doors with a short, friendly script and a leaflet with your prices and contact details. Spring evenings and weekends work well.
- Set up a Google Business Profile. Add your service area, photos and services. You can publish updates and offers, such as a first-clean deal for new customers.
- Leave cards after each job. Drop a card at the neighbors' doors saying you clean number 14 every four weeks and would be happy to quote.
- Approach local shops. Walk your high street early in the morning and offer a free trial clean of one window to show the difference.
- Ask for referrals. Offer a free clean for every new customer a client recommends.
Pro tip
Leave a short "Your windows were cleaned today" card after every visit, with the date of the next clean and how to pay. It reminds customers you were there, prevents payment confusion and makes it easy for visitors to find you.
Booking, payment and records
Use a simple system to track your round, due dates and payments. A booking tool such as Calendly, Acuity Scheduling, Square Appointments or SimplyBook.me can handle quotes and one-off jobs, while your regular round can live in a spreadsheet or round-management app. Offer easy payment options such as bank transfer or card, and send invoices promptly. Check current features, pricing and privacy policies before choosing any tool.
Weather will interrupt your schedule. Decide your policy for rain and very cold days, tell customers up front, and send a quick message when you need to move a visit.

Frequently asked questions
Do I need a license to start a window cleaning business?
It varies by location. Some cities, counties and councils require a general business license or permit, while others do not. Check with your local government before you start, and make sure you follow the work at height and safety rules for your country.
Is a water-fed pole system worth it for a new business?
For many residential rounds, yes, because it lets you clean upper windows from the ground, which can be safer and faster. It does cost more to set up. Some owners start with traditional kit on ground-floor work and add a water-fed system once their round grows.
How often do customers want their windows cleaned?
Homes are often cleaned every four to eight weeks, while shopfronts may want weekly or fortnightly visits. Offer a few simple frequencies and let customers choose what suits them.
Can I run a window cleaning business part time?
Yes. Many people start with evening or weekend rounds and grow until the business can replace their income. Just be clear with customers about when you work so you can stay reliable.
