Regal Maid Service is a wise investment in an outstanding growth industry. The housecleaning industry represents more than $51 billion in annual revenue and demand is projected to grow by 7% annually. More people than ever before now spend free time with family and friends, rather than cleaning the house. Housecleaning will also continue to be a people-based industry. Customers prefer a careful, hands on approach to cleaning that protects their homes and possessions.
