and the part most guides leave out.

What nobody usually tells you
Recurring by nature: the same windows get dirty every month forever, and rounds are bought and sold as assets. Weather-dependent and physically repetitive, but the income is more predictable than almost anything else here.
The route, in five steps
Buy a pole-fed system: no ladders, no ladder insurance
Buy an existing round if one is for sale — instant income
Shops and offices, monthly, on contract
Cluster by street to cut driving to nothing
Raise prices 5% a year automatically
What you'll need to buy
These are the categories every commercial window cleaning pays for in the first month.
We break down what each one actually costs at this size on the
tools page.
