WARNING
In recent years, insurance costs increased so much that small-sized enterprises cannot afford them. Even medium-sized companies are forced to seek a compromise and opt in for janitorial or cheaper window cleaning insurance with limited or no coverage for window cleaning operation with height exposure above the 4th story.
To check what is covered by the insurance policy, you can simply call the insurance agent mentioned in the provided COI (certificate of insurance) and ask them whether the policy covers window cleaning operation and what the height limit is.
