The typical tasks a cleaning service will perform often vary among companies. Typically, the service will dust furniture, picture frames, lamps, woodwork, and other places where dust gathers; vacuum carpeted floors; wash non-carpeted floors; clean and sanitize counters and backsplashes; clean and sanitize some appliances; clean and sanitize showers, sinks, and toilets in bathrooms; and wipe mirrors.
Some companies provide additional services, such as laundry and polishing silverware. Some will wash windows, but homeowners looking to have this done may want to contact a company that specializes in window cleaning, because they will have the equipment and training necessary and to handle this task.
It is not acceptable to expect service providers to do anything that may endanger their own health, such as lifting heavy objects, climbing tall ladders, or cleaning up hazardous waste, such as blood, human waste, or mold.
