How to Start a Window Cleaning Business: The Complete 2026 Roadmap

Window cleaning is one of the cheapest trades to start. A bucket, a squeegee, a ladder, and a few good customers will get you paid. It is also one of the easier trades to get hurt in, and one of the easiest to underprice. This guide covers both.

The industry is bigger than most people think. IBISWorld puts window washing at roughly $2.9 billion a year in the U.S., spread across about 35,000 businesses (2024 figures). Most of that revenue comes from commercial work, with households making up a smaller but still real share. That is a lot of small shops sharing a lot of glass. A one-truck owner-operator with a tight route can do well here.

What follows is the order I would do things in if I were starting today. We start with the safety rules, because that is the part that can end your business (or worse) before you send a single invoice. Then licenses, insurance, gear, pricing, your first customers, and growth. It is a national overview. Licensing, tax, and workers' comp rules change by state, so where it matters I will tell you what to look up and where to look it up.

1. Decide what you will clean (and where you will stay on the ground)

"Window cleaning" covers more than one business. Pick your lane before you buy gear, because the lane decides your tools, your insurance, and your schedule.

• Residential exterior is the easiest door to walk through. Homeowners book a one-time clean or sign up for a quarterly or twice-a-year visit.
• Residential inside and out takes longer per house and pays more per visit.
• Storefronts and small commercial run on short, repeat stops: a dentist's front glass, a salon, a row of shops in a strip mall. The tickets are small. The route is the business. (Bit & Grain's window cleaning page shows what a week of routes looks like in the app.)
• Add-ons like screens, tracks, hard-water stain removal, skylights, and storm windows bring in extra money on the same visit.
• High-rise and rope work is a different business with different training, gear, and rules. Leave it alone for now.

My advice: start with residential exterior plus a handful of storefronts, and keep your feet on the ground or on a short ladder. A water-fed pole (more on that below) lets you reach second and third stories without leaving the ground at all. You can add interior work, gutters, and bigger buildings once you have cash flow and a feel for your numbers.

2. Learn the safety rules before you buy anything

Falls are the main way people get killed or crippled in this trade. Learn this part first and you get to keep working for the next thirty years.

For scale: the Bureau of Labor Statistics counted 5,070 fatal work injuries in the U.S. in 2024, and 844 of them came from falls, slips, and trips. OSHA has also said falls are among the most common causes of serious injury and death for window cleaners. In 2010 it signed an alliance with the International Window Cleaning Association aimed at fall hazards and safe ladder use.

What OSHA says about ladders

Window cleaning work is usually covered by OSHA's general industry rules (29 CFR Part 1910). If you clean on an active construction site, the construction rules in Part 1926 may apply instead. If you are not sure which one covers a job, ask OSHA or your state plan before you climb. Either way, here are the basics from the text of 29 CFR 1910.23:

• Inspect the ladder before first use on every shift. If it is damaged, tag it "Dangerous: Do Not Use" and pull it out of service until it is fixed or replaced.
• Face the ladder when you climb up or down, and keep at least one hand on it. Do not carry anything that could throw off your balance.
• Stay under the load rating. The weight counts you, your tools, and anything else you carry.
• Extend the side rails at least three feet above the landing when you use a ladder to get onto a roof or upper level.
• Never stand on the top step or cap of a stepladder.
• Set the ladder on a stable, level surface or secure it. Do not stack it on boxes or barrels for extra height, and do not move or extend it with someone on it.

The familiar 4 to 1 setup (one foot out at the base for every four feet of ladder length to the support) is written into OSHA's construction ladder standard, 29 CFR 1926.1053, and the general industry rule shows the same setup in its figures. Use it everywhere. That standard also calls for ladders strong enough to hold at least four times the maximum intended load.

One more note on ladders and roofs: OSHA's general industry fall protection rule, 1910.28, requires guardrails, nets, or personal fall protection wherever there is an unprotected side or edge four feet or more above a lower level. Portable ladders are carved out of that section, which is why the ladder rules above are about setup and habits instead of harnesses. If a job means stepping onto a roof or working near an edge, that is a different conversation, and you need the right gear and training first.

Rope descent is not a beginner skill

You will see window cleaners hanging off tall buildings. That work falls under 1910.27. Before anyone uses a rope descent system, the building owner has to give you written confirmation that each anchor can hold at least 5,000 pounds per attached worker. Every worker needs their own separate fall arrest system, training, a rescue plan, and a start-of-shift inspection. None of that belongs in your first year. If a customer asks for it, refer it out.

Why a lot of owners switch to water-fed poles

A water-fed pole is a telescoping pole with a brush at the top and purified water running through it. You clean from the ground. That means no ladder setup, no climbing, and no carrying a bucket up a rung. It also means you are trading ladder risk for strain risk from holding a long pole, so pick the lightest pole that reaches the top of the window and do not over-reach (the IWCA's water-fed pole safety module says the same). Carbon fiber poles conduct electricity, so look up before you extend, and keep well clear of power lines.

Get trained and write your rules down

OSHA's State Plans page lists the 29 states that run their own OSHA programs. Those states can have stricter rules than the federal ones. Look yours up. The International Window Cleaning Association (IWCA) publishes the ANSI/IWCA I-14.1 window cleaning safety standard along with safety resources, so go see what they offer. Write down your own short rules for ladder inspection, weather, and power lines, and follow them on every job. Your startup checklist should include them.

3. Check what licenses and permits you need

In most places there is no trade license for window cleaning the way there is for plumbing or electrical work. Next Insurance says there is generally no occupational window washer license, and that most window cleaning businesses need to register with the state and pay the taxes that apply.

Plan to check these:

• A general business license from your city or county.
• State registration and tax accounts (more in the entity and taxes steps).
• Sales tax rules for cleaning services. Some states tax services and some do not. Your state's revenue department can tell you.
• Wastewater and runoff rules. Some cities regulate water use or runoff, especially for water-fed poles or work near storm drains.
• Permits for tall buildings or lifts, if you ever go there.

Check your state

Licensing rules change by state and often by city. The SBA's license and permit guide walks through how to find what applies to you, and its register your business page points you to your state's Secretary of State. Call your city clerk too. Five minutes on the phone now beats a fine later.

4. Make it legal: your business entity

Most window cleaners start as a sole proprietor or a single-member LLC. A sole proprietorship costs nothing to set up, but your personal assets sit behind every claim. An LLC separates the two, and it does not replace insurance. In a trade where a ladder can crack a pane or gouge a lawn, I lean toward an LLC plus a solid policy. The SBA's guide to choosing a business structure lays out the options, and your state's rules and fees differ, so check yours. If you are unsure, a short talk with a local accountant is cheap insurance.

Get your EIN (employer identification number) from the IRS. It is free to apply online, and it keeps your Social Security number off invoices and vendor forms. Then register your business name. If you will operate under something other than your legal name, file a DBA ("doing business as") with your state or county.

5. Get insured before you touch a customer's glass

Do this before your first paying job. A cracked pane, a scratched sill, water through a ceiling, a fall from your ladder on a customer's property: any one of these can cost more than a year of profit. Commercial customers and property managers will also ask for a certificate of insurance before they let you work.

Coverages that matter for a window cleaner:

• General liability covers property damage and third-party injury. Expect to carry it before any commercial account hires you.
• Commercial auto covers the vehicle you use for work and the gear inside it. Personal auto policies often exclude business use.
• Workers' compensation is usually required by law once you have employees, and the rules vary by state.
• Tools and equipment coverage protects your gear from theft or damage.

Insureon (updated September 2026) reports an average of $78 a month ($931 a year) for general liability for small window cleaning businesses, $114 a month for workers' comp, $81 a month for a business owner's policy, and $250 a month for commercial auto. The workers' comp, auto, and BOP figures are based on cleaning businesses more broadly. Next Insurance says 45 percent of its window cleaning customers pay between $38 and $51 a month for general liability. Rates swing by state, coverage limits, and whether you use subs, so get at least three quotes. These are insurers' own numbers, so treat them as ranges, not promises.

6. Set up the money side

Open a separate business checking account the same week you register. Mixing personal and business money turns tax time into a mess and weakens the liability protection an LLC gives you. A business credit card is helpful too: it makes receipts easy to sort later.

Decide how you will get paid before the first job. Residential customers expect to pay by card or digital payment on the spot. Commercial accounts often want an invoice and net-15 or net-30 terms. Offer card payments from day one, since a lot of homeowners will pay the moment the glass looks good. Bit & Grain's estimates and invoicing sends the invoice and takes the card payment through Stripe, so the money lands in your bank and the invoice marks itself paid.

7. Buy your gear (ladder route or water-fed pole route)

You can start two ways. They cost very different amounts.

The ladder route: low cost, more risk

Start-up estimates for a traditional setup run from about $500 to $3,000, according to Wexford Insurance's 2026 cost breakdown. Next Insurance quotes about $500 to $1,500 for basic tools alone. What goes in the bucket:

• Starter squeegee kits: Window Cleaning Resource sells a Moerman 5-in-1 starter kit for $58.59 and a 9-in-1 kit for $191.70. A bigger Sörbo Advanced Kit with a rolling cart is $890.17.
• A good ladder. A 24-foot Type IA fiberglass extension ladder runs about $400 at a big-box store (Home Depot lists the Werner D6224-2 at $399). Buy for the load rating, not the price.
• Ladder stabilizers, leg levelers, non-slip boots, gloves, towels, scrapers, and a bucket.
• A vehicle. Most one-person shops start with whatever they already drive.

The water-fed pole route: higher cost, ground-level work

Water-fed systems cost more, but they cut ladder time and let you reach higher glass from the ground. Wexford puts a full water-fed setup (poles, plus the pure water system) at $2,000 to $15,000 or more. Catalog prices from Window Cleaning Resource in October 2026:

• A 36-foot PWP carbon fiber pole: $434.50. A 57-foot high-modulus carbon pole: $1,143.50. These are the pole only; you still need a way to make pure water.
• The Unger nLITE Carbon starter kit: $623.20 (33-foot).
• A complete setup with a pure water system: the XERO Ultimate Residential Kit MAX is $3,799, and the Unger HydroPower Nano Professional 39-foot kit is $4,999.
• A truck-mounted pure water unit like the Skid Marc is $7,499.

My take: start with the ladder route if you are cash-tight, keep to one-story and low second-story work, and save up for a pole once your first route pays for it. A pole earns its keep fast on storefront strips and two-story homes. Pure water is why the glass dries spot free, so budget for filter media and refills too.

8. Set your rate (do not guess)

This step decides whether you get paid for your time or work for free in the sunshine.

Two ways to price

• Price by the window or pane. Fast to quote and easy for customers to understand. Housecall Pro's 2026 pricing guide (which pulls from Angi, HomeAdvisor, Thumbtack, and BLS data, and reflects what homeowners say they pay) shows $4 to $8 per pane, or $10 to $18 per window, with typical jobs of $150 to $275 for 10 to 15 windows and $250 to $450 for 20 to 25.
• Price by time. Better when scope is unclear. The same guide puts hourly rates at $45 to $75 per cleaner for residential and $50 to $100 for commercial.

Add the extras that make money

• A minimum charge. The guide shows $100 to $150 or more for small one-time jobs. A single window across town should not cost you money.
• A height or access surcharge. 10 to 30 percent or more for ladders, roofs, and hard-to-reach glass.
• Extras priced separately: screens ($2 to $5 each), track detailing ($3 to $6 per window), hard-water stain removal ($20 to $75 or more), skylights ($10 to $25 each).

Storefront routes: price the stop, not the pane

Storefronts live and die on route density. Housecall Pro's guide lists a flat rate of $40 to $75 per visit for small recurring storefronts, and notes a weekly route stop can take about 20 minutes. Do the math with your own hourly number: stop time, plus drive time between stops, plus a share of your insurance and truck costs. Then set a monthly minimum so a single door and one window does not drag your route down. Window cleaners on the Window Cleaning Resource forum have talked about this for years: some bill by the minute with a minimum, some use a flat monthly number for a tiny stop. Those posts are from 2014, so use them for the method, not the numbers.

A recurring customer is worth discounting. The Housecall Pro guide shows about 8 to 15 percent off for quarterly service and up to 20 percent for monthly. Give the discount for the commitment (a signed plan), not just for coming back more often. For a storefront on a monthly plan, a $60 visit is $720 a year from one front door. Ten of those on one block is a real route.

Use a calculator, then check the market

Take your hourly target, your costs, and your time per job, then run it through a calculator before you quote. Our free trade calculators and tools include a job cost estimator that adds labor, materials, markup, and tax so you can see your margin. Then check two or three local competitors. If you are far below the market, you are working for less than you should.

If you want a head start, the $49 Window Cleaning Business Starter Kit packs everything for this step: a pricing calculator spreadsheet that prices by the window with height surcharges and prices storefront routes by the month, an estimate and invoice spreadsheet, a recurring service plan form in Word and PDF, and a startup checklist covering licensing, insurance, ladder safety, and equipment. It is one payment, and the files are yours to keep.

9. Build your brand and web presence

Pick a name that says what you do and where you do it. "Clear View Window Cleaning" beats a clever word nobody can spell. Check that the name is free in your state's business search and that nobody near you uses it.

Get the domain first. Register it at a registrar like Namecheap, Porkbun, or Cloudflare Registrar. Keep it short, use the .com if it is available, and avoid hyphens. Then set up a professional email address on your own domain (Google Workspace is the common choice). A customer is more likely to trust you@yourbusiness.com than a free webmail address.

Then build a simple site: your services, your service area, a few before-and-after photos, and one way to book or call. Photos of real glass you cleaned beat stock images every time. If you want people to book without calling, add a booking form to your site.

10. Set up your operations system

This is where new owners quietly lose money. Window cleaning is small tickets and lots of repeat visits, which means lots of little dates to remember. A paper route sheet and a notes app will work for about two months.

You need a place to hold five things: your customers, your recurring schedule, your estimates and invoices, your payments, and your expenses. Bit & Grain is built for that: $29 a month with Grain AI included, a 30-day free trial, and no credit card to start. You can see the full plan details on the pricing page.

Here is how the pieces map to this trade:

• Recurring schedule. Quarterly houses and monthly storefronts need to come back on their own. Recurring invoices handle the billing, and the calendar keeps the next visit in front of you, so nobody slips through because you forgot to call.
• Route planning. Route planning lines up the day's stops so you drive less between them. In a trade built on route density, that saves real money.
• On-site estimates and invoices. Quote from the driveway and send the invoice before you load up the truck. Customers pay faster when the bill lands while the glass is still clean.

The phone app is one download on the App Store and runs on iPhone, iPad, and Apple Watch. Once you are parked between stops, you can pull up the next address, check the notes on the customer, and close out the invoice. Grain AI is included in the plan, so you can talk to the business by voice or chat instead of typing on a wet screen.

11. Get your first customers

You do not need a big marketing budget. You need to be easy to find, easy to trust, and on a street where you already have neighbors.

Google Business Profile (free, do this first)

Create your Google Business Profile, add your service area, upload real photos, and list your services. For a service business, this is the cheapest lead source you have. When someone searches "window cleaning near me," you want to be on the map.

Get reviews early and often

Ask every happy customer for a review while the glass is still sparkling. A short text with a direct link works. Bit & Grain's review requests send a polite request after you close a job so you do not have to remember. Ten honest reviews do more than a pretty website.

Work your neighborhood

Window cleaning is a local trade, and density is profit. After you finish a house, knock on the two next door and offer a neighbor rate. Leave a door hanger with your number and a short offer. Do the same in strip malls: a clean storefront next to a dirty one sells itself.

Referral and lead sources

• Property managers, realtors, and builders. A property manager who likes you can hand you a dozen buildings. Realtors need clean windows before listing photos.
• Local business groups and chambers of commerce.
• Nextdoor and neighborhood Facebook groups. Answer questions, show photos, and do not spam.
• Post-construction cleaning, which is a good fit once your insurance and safety habits are solid.

Show your work online. A before-and-after photo of a cloudy storefront does more than a slogan. Bit & Grain can turn job photos into captions you post to Facebook and Instagram, which saves you the blank-page problem.

12. Run jobs like a pro

Little things on the job site decide whether a customer rebooks.

• Put the scope in writing. Inside, outside, or both. Screens or no screens. Which windows count. What happens with locked or blocked windows. A written scope stops the argument before it starts.
• Photograph existing damage. Scratched glass, cracked seals, failed caulk. Take a photo before you touch it and note it on the invoice.
• Check the weather. Wind, rain, direct sun, and freezing temperatures all hurt the result and the safety of your ladder setup. Reschedule instead of forcing it.
• Set an add-on rule. If a customer asks for screens or track cleaning on the spot, quote it right there and get a yes before you start. Do not do extra work and hope for the best.
• Tell customers what to expect. A text the day before with your arrival window saves phone calls and no-shows.

A written service plan is the cleanest way to lock in a recurring customer: it states the frequency, the price, what is included, and how to cancel. That is why the kit includes one as a fill-in form.

13. Track your money and stay ready for taxes

When you are your own boss, nobody withholds your taxes. Plan for them from your first invoice.

Track every expense

Squeegee rubber, microfiber, pure water filter media, insurance, ladder repairs, gas: it all counts. Snap a photo of each receipt the day you spend the money. Bit & Grain's receipt scanning reads the receipt from the photo, so you are not dumping a shoebox on your accountant in April.

Track your mileage

Window cleaners put on a lot of miles between stops. The IRS standard mileage rate started 2026 at 72.5 cents per mile, and the IRS can adjust it, so check the current rate. Drive 15,000 business miles at that rate and you are looking at about $10,875 in deductions you cannot afford to lose. Mileage tracking in the iPhone app logs a trip when you tap Start Trip before you head out and End Trip once you are parked.

Pay quarterly estimated taxes

As a self-employed owner you owe self-employment tax of 15.3 percent on net earnings, on top of income tax. If you expect to owe more than $1,000, the IRS wants quarterly estimated payments (Form 1040-ES). A safe habit: set aside 25 to 30 percent of every dollar of profit as it lands. If your state charges sales tax on cleaning services, collect it and file on time. Your state's revenue department site is the place to check, and the IRS keeps a list of state government links to help you find it.

14. Grow

Once your route is steady and your numbers are clear, grow on purpose.

• Build recurring revenue. Quarterly residential plans and monthly storefront contracts smooth out the slow weeks. A route of 40 recurring stops beats 40 one-time customers every time.
• Invest in the pole. When you are turning down work because of reach or time, buy the water-fed system.
• Hire your first helper. An employee means workers' comp, payroll, and training on your safety rules. Teach them your ladder habits before they carry a squeegee.
• Add commercial accounts. Move toward offices, restaurants, and property managers once your insurance and certificates are in order.
• Raise your prices once a year. Fuel, insurance, and gear go up. Your rates should too.

The bottom line

Window cleaning is cheap to start, easy to learn, and easy to underprice. The owners who last learn the safety rules first, carry real insurance, price by the numbers, and build recurring routes. The gear is simple. The habits take work.

Bit & Grain is built to keep the business side in one place so you can stay on the glass: estimates, recurring jobs, invoices, payments, mileage, and receipts, with Grain AI included for $29 a month. Start your 30-day free trial and see how it fits your route.

Now go clean some glass.
