Unless you have an inspection only or oil and grease only contract the elevator company that has been hired to do maintenance is usually responsible for preventing basic defiance's like dirty car tops, pit, machine room, emergency lighting, bells, house keeping etc.. You should not have to hire another company to do work that the first company should be responsible for. If they refuse to take care of these issues you need to read the fine print in your contract. If you do not know when kind of wording you need to represent you in an elevator maintenance contract you should hire an elevator consultant to help you.
