How to start a janitorial service
Set yourself apart.
The business owner should work personally when starting the business to assure quality standards are met, because reputation is the main ingredient for success. When you begin to hire employees, they must be trained to meet the high standard your customers will expect.
Also, it is a great idea to do the things other janitorial services do not offer (i.e. doing windows, cleaning litter boxes, cleaning your refrigerator, or car), because that makes your business unique meeting individual needs.
