Questions people ask

Do you need a licence to start a pressure washing business?

Usually just a general business licence from your city or county. Some states license home improvement contractors, and some cities need a permit for washwater.

Can pressure washing water go down the storm drain?

No. Under the Clean Water Act and local rules, washwater must not go into storm drains. Send it to a grassy area or collect it and dispose of it properly.
