Added to the basic services of straightening the house, dusting and vacuuming is a program called Level 2 that is being tested and will be available to all The Maids’ 500 markets in spring 2001. In addition to carpet cleaning, complete window cleaning and valet laundry/dry cleaning service, the Level 2 service will also extend to include furnace filter changing. These services have been added to help expand The Maids International cleaning for health focus, the company says.
