If you are considering a small company that has a limited number of employees, be sure to ask about cleaning over holidays or during times when the cleaning company may be short staffed due to illness. How will this be handled or will cleaning services go on as normal? How is replacement staff selected in these conditions and are all security concerns addressed?
There are a number of different types of janitorial cleaning services that you can take advantage of. Each offers their own specialization. You obviously do not want the same service for a school as you would for a hospital. Therefore, when selecting these services, find out what they specialize in first.
