How can I clean on the side do I need to be bonded to clean a bank?

There are several threads here about cleaning businesses. I suggest you read them and, if you have any specific questions, feel free to ask.

ScottGem is one hundred percent correct...

Some quick advice; to clean a bank you usually need to survive a security check. Whether you work for a cleaning company or you do it as a side job. Do you have any experience? We need to know a lot more about you and what you plan on doing and how before any of us can give you useful advice.

If you are planning on doing this as a side job, yes you will need liability insurance just like any 'company' would. A reputable bank would require this. And they may require that you be bonded, something totally different from liability ins. Which I am sure they will require also.

Would you like to know how to advertise your business for free on the Internet so that it will get excellent exposure when people do searches for what you do where you do it? I can definitely help you with that. Please let me know if you are interested.

Thanks!

Well first clean on the side? Side of the bank? Or do a cleaning business as a part time job from your regular job.

Do you currently work for a cleaner ? If so is there an agreement you can't do off duty jobs that compete ? Do you work for the bank. For example I work for a company that sells cleaning supplies, I can not do cleaning jobs since it takes away jobs from my customers.

As for as being bonded, if the bank requires it, yes, if they don't know.
