01Is it right for you?

A good fit if you like visible results and working outdoors

10Questions

Common questions

Do I need a license to clean windows in Canterbury?

Usually there's no special license for window cleaning. You'll register your business, and once you hire, workplace safety rules for ladders and heights apply.

Can I start part-time?

Yes. Many window cleaners start on weekends with two or three homes, then go full-time once spring and fall bookings fill up.

Do I need a water-fed pole?

Not to start. Hand tools and a good ladder handle most homes. A water-fed pole lets you clean upper outside windows from the ground, which is faster and safer.

How often do customers book?

Most homes are cleaned twice a year, in spring and fall, and some every quarter. A plan with a small discount keeps them coming back.

What about winter?

It's quieter, especially in cold places. Many window cleaners save during the busy months and add storefronts, gutters or holiday work.
