I am in the beginning stages of starting up a cleaning service. Thus far, its only been family. Do you usually clean while the person is at home, if not how do you go about getting into the house? In this day and age people are so skeptical (and I don't blame them) is it distressing to suggest having a copy of the key? Maybe a good jumping off point is to start by suggesting that they leave a key somewhere... mailbox,doormat, etc. I used to work for Merry Maids (long time ago) and I can't remember.
