How to start a window cleaning business
Starting a window cleaning business means registering a business, getting insured, buying your first equipment, and pricing your first jobs by real cost instead of a guess. Here's the order to do it in, what it actually costs, and where new operators lose money in the first year.

Six steps to get running
-
Get licensed and insured
Register your business and get general liability insurance — carry higher coverage than some trades, since ladder and height work carries more liability. Most residential and light-commercial work needs no special permit.
-
Buy your first equipment
Ladders, a squeegee and solution kit, and a basic water-fed pole system are enough to start. Most residential window cleaning needs no specialized certification.
-
Price your first jobs correctly
A flat per-pane rate ignores access difficulty, which moves the real cost more than pane count does. See the full pricing guide for the formula.
-
Find your first customers
Set up a free Google Business Profile, post in local Facebook groups and on Nextdoor, and try direct outreach to storefronts for recurring commercial routes.
-
Track jobs and get paid
Even one ladder needs a system for quotes, jobs, and invoices — a notebook or text thread stops working the moment you're juggling residential jobs and a storefront route.
-
Grow beyond the first ladder
Once you're consistently full, the next bottleneck is usually storefront routes and commercial bids — that's the point to start tracking recurring accounts and larger project scope separately.
What it actually costs to start
| Startup cost | Typical range |
|---|---|
| Ladders, squeegees, solution | $300–$1,500 |
| Water-fed pole system | $500–$3,000 |
| General liability insurance (annual) | $500–$2,000 |
| Business registration & permits | $50–$500 |
| Typical total to start | $1,500–$8,000 |
The lowest startup cost of these five trades — a ladder and a basic solution kit are enough for most residential work before a water-fed pole system is worth adding.
Common early mistakes
A ground-floor pane and a second-story pane behind a fixed shutter are not the same job — build access difficulty into the rate.
Ladder and height work carries real liability — skipping a basic safety plan to save time is the most expensive early mistake in this trade.
Storefront work is won on route reliability and volume, not the lowest price — a rate that only works at high volume breaks the moment one stop drops off.
