How to start window cleaning business: launch order
How to start window cleaning business: an owner-operator launch order for registration, insurance, safe access, pricing, and first customers.
What to take away
- The question “how to start window cleaning business” has a practical answer: work in this order—legal footing, insurance, one repeatable method, then customers. Reversing any two of those creates a problem you fix later at a higher price.
- Your first month should produce a written scope, a written price basis, and a written safety limit. Those three documents are the business.
- Do not buy a full kit before you have cleaned twenty paid windows. You will replace half of a guessed kit.
- Chase density, not volume. Ten accounts on one street outperform twenty scattered across a county.
- Build your budget from written quotes from your suppliers, insurer, and local licensing offices; requirements and prices depend on your address and setup.
Height work, ladder use, lifts and rope access carry real risk of serious injury. Get competent training and qualified advice for the access methods you intend to use before you accept work that needs them.
The first twelve weeks, in order
This is a sequence, not a checklist. Each step assumes the one above it is finished.
First Twelve Weeks, In Order
- Register the business
- Open a separate bank account
- Get insured before touching property
- Set your access limit in writing
- Buy the minimum kit and use it
- Register the business.Choose a structure. To form an LLC or corporation, file the required formation document—commonly articles of organization or articles of incorporation—with your state's Secretary of State or equivalent filing office. If a sole proprietor uses a trade name, check whether a fictitious-name or DBA filing is required. Get an EIN through the IRS EIN Assistant when needed. Then ask your city or county business licensing office whether a local general business license or permit applies to your address; there is no single nationwide window-cleaning permit. The detail varies enough that you have to read it for your own address; the licensing and compliance requirements for a cleaning company are stacked from several offices rather than issued by one.
- Open a separate bank account.Same week. Mixing personal and business money makes your first tax filing expensive and your first year of records worthless for pricing.
- Get insured before you touch a customer's property.Carry general liability at minimum as your baseline. Ask the broker about workers' compensation if you hire employees, commercial auto coverage for business vehicle use, and whether an umbrella policy fits your contracts and exposure. Requirements depend on your state, workforce, vehicle, and access methods. Commercial customers will ask for a certificate before they ask for a price.
- Set your access limit in writing.One page: the maximum height and the access methods your company performs, and who can approve an exception. OSHA's General Industry standards for Walking-Working Surfaces and Ladders, and its Construction standard for Fall Protection, may apply depending on the work and access method. Get qualified advice on which requirements apply before setting your limit.
- Buy the minimum kit and use it.Squeegee, channels and rubber, applicators, buckets, detailing cloths, scrapers, ladders you are trained on, and a way to carry water. Nothing else yet.
- Clean twenty paid windows at a deliberate loss if needed.You are buying data: how long a storefront pane takes, how long a residential double-hung with screens and tracks takes, and what slows you down.
- Write the method down.The order you work a pane, the order you work a building, what gets detailed, what gets photographed. This is what makes a second person possible later.
- Build the price basis from your own timings.Not from a competitor's flyer. Time and materials first, then convert to the unit your customers understand.
- Write the agreement.Scope, frequency, access, weather, price review, notice on both sides. One document, reused.
- Sell into one geographic pocket.Walk a commercial strip, introduce yourself to storefront owners, and ask neighboring businesses and property managers for introductions. Leave contact information and note which blocks show interest and where the work fits your written scope. Cheap, unpopular, and still the fastest route to a dense route.
- Put the schedule in one place.Paper is fine at ten accounts and dangerous at thirty. Choose the system before you outgrow the notebook.
- Review week twelve honestly.Revenue per working day, unpaid driving time, and how many customers rebooked. Those three answers decide what you do next.
What to get right before you are busy
Three things are cheap now and expensive later.
Get Right Before You Are Busy
- Named scopewhat is included at standard price
- Named scopewhat is extra
- Before-and-after photos on every first visit
- Photos of every pane with existing damage
- Ask the rebooking question at every job
- Put the next date in the calendar there
A named scope. Interior and exterior, screens, tracks, sills, frames, hard-water spotting, skylights, and what you do with furniture in the way. Write which of those are included at your standard price and which are extra. Almost every dispute in this trade is a scope dispute wearing a price costume.
A photograph habit. Before and after, on every first visit, on every pane with existing damage. Scratched glass and failed seals are pre-existing conditions that customers discover on the day you cleaned.
A rebooking question. Ask at the end of every job whether they want it on a schedule, and put a date in the calendar there and then. Recurring work is the whole difference between this and a job.
Money in the first year
New owners underestimate two costs and overestimate one.
First-Year Cost Expectations
Underestimated
- Consumables
- Rubber, cloths, pads wear fast
- Payment gap
- Commercial accounts pay on their cycle
- Initial kit
- Genuinely modest at ground level
Overestimated
- Consumables
- Not a major cost
- Payment gap
- Not a major cost
- Initial kit
- Owners expect it to be huge
Underestimated: consumables and replacements, because rubber, cloths and pads wear out faster than any budget expects, and the gap between doing the work and being paid, because commercial accounts pay on their cycle. Overestimated: the initial kit, which for ground-level work is genuinely modest.
The SBA Business Guide from the U.S. Small Business Administration sets out funding, permits and structure in roughly the order these decisions arrive.
The Internal Revenue Service's Starting a Business guidance covers what you are expected to have in place from the first invoice, not at year end.
Read both before you commit to a structure. Changing it later costs more than choosing it slowly.
For the vehicle and gear decisions themselves, work through the window cleaning equipment and setup choices rather than copying a supplier's starter bundle.
When to stop working alone
The signal is not revenue. It is a full working day with no gaps, on the same weekday, in the same area, week after week. That is the point where a second pair of hands has real work rather than expensive idle time.
Before that day arrives, write down the arrival checks, access and scope notes, work sequence, and closeout routine so someone else can follow them. Make daily operations and workflow a routine the crew can use on every job.
Settle your hiring and training window cleaners plan before you are desperate; train new workers on the written scope, access limit, and photo habit before they work independently.
Getting found is the other half. Alongside the marketing and growth plan, contact property managers directly and ask satisfied customers for introductions to nearby businesses or neighbors. Keep new inquiries in the pocket you already serve, so they land where your van already is.
Common questions
How long before this replaces a full-time income?
Nobody can tell you that from a page, and anyone who gives you a month count is guessing. What you can measure is the rate: how many recurring accounts you added per month, and what each is worth per year. Two months of that data forecasts better than any article.
Do I need a website before I start?
You need a way to be found and a way to be believed. A listing with real photographs, real hours and real reviews does more early work than a website nobody visits. Build the site when you have work to show.
Should I offer pressure washing and gutter cleaning too?
Eventually, and deliberately. Adding a second trade before the first one is repeatable doubles your equipment cost and halves your attention. Add it when the glass work runs without you thinking about it.
What is the most common early mistake?
Pricing from a competitor's number instead of your own timings. It survives right up until you hire somebody, and then it fails all at once, because the price never carried a wage.
