In business, the term "overhead" relates to your operating costs. However, when it comes to the physical location of your business, "overhead" has a completely different meaning. In this sense, it relates to the objects that are above you and out of reach — and this is especially an issue in certain parts of your building that may have high ceilings, such as your warehouse. When it comes to having these things cleaned regularly, you want to hire a janitor service that specializes in overhead work.
It's hard to juggle a work and home balance. Being gone at work all day, coming home to try and spend time with your family, and then having to also worry about the cooking and cleaning of your home. It can become quite a juggling act, and in the end, your housekeeping gets neglected - dishes pile up, laundry seems to be spilling out of the laundry baskets, and the dust is so thick you can write your name in it.
