01Is it right for you?

A good fit if you love a dramatic before and after

Pressure washing gives customers a dramatic before and after in a few hours. You can start with one good machine and a surface cleaner, then add soft washing for siding and roofs as you learn. Spring and summer are busy, and many homes book again every year.

10Questions

Common questions

Do I need a license to pressure wash in Bay of Plenty?

Usually there's no special license, but check your area's wash-water rules: many places fine runoff into storm drains. A few states treat some pressure washing as contractor work.

What's soft washing?

Soft washing cleans siding and roofs at low pressure with a cleaning mix, mostly diluted chlorine. High pressure is for concrete. Using the right one avoids damage.

Can I start part-time?

Yes. Many owners start on weekends with driveways and house washes, then go full-time once spring bookings fill up.

Is there a busy season?

Spring and summer are busiest, and winter is slow in cold places. Save during the busy months and book yearly reminders early.

What sells best?

House washes and driveways, and bundles of both. Decks, fences and gutter faces make easy add-ons.
