Are you cleaning just one or a bank of them? Flooring? Service elevators or passenger elevators? If we're just cleaning one or two we charge 1-1.5 hours, which includes us showing up, carrying in supplies, cleaning and then packing up and back to the van. If we're cleaning more than two we'll drop the rate a little. Some service elevators take a little longer too if you have to take off the padding on the walls and hang it back up. We bid some before without the padding on and showed up with it on. Just something to look out for.
