Exterior cameras specifically, typically require lift equipment which, whether owned or rented, is billed to the customer. We bill a slightly higher rate for the bucket trucks due to the increase in liability insurance costs for those pieces. Based on those costs alone, many customers have a difficult time with the value proposition. But we will always execute more than one maintenance task at a location if we are already there working on that unit. On site-wide cleaning, we recommend they have their Maintenance Dept do it, and offer a service contract should they decide to have us do it.
