|PMM’s PARTNERS – AT ONCE CLEANING,
ARROW CROWN & HEARN MORILL
In 2007, PMM Companies expanded its reach in the Washington, DC and the Baltimore, MD area by acquiring At Once Cleaning Services, Inc, now PMM of Baltimore. PMM of Baltimore is a large janitorial contract cleaning organization servicing large office buildings and non-profit institutions. Today, PMM of Baltimore continues to operate as a subsidiary of PMM Companies.
In 1979, PMM of Baltimore began its operation with one premise: to provide professional janitorial services. Tasks ranged from post construction cleaning and daily contract staffing to detailed residential duties inclusive of carpet and floor cleaning services. PMM of Baltimore achieved growth and matured with a quality reputation throughout the Baltimore/Washington Metropolitan areas.
In 1986, PMM of Baltimore purchased Arrow Crown Window Cleaning Contractors, a Baltimore based company since 1958. Together, PMM of Baltimore and Arrow Crown were able to provide customers with one complete package.
||Over the next decade, both companies grew becoming the popular choice selected by directors of many non-profit institutions. Additionally, project managers of several construction companies insisted that PMM of Baltimore/Arrow Crown be retained for their construction cleaning projects.
In 1995, PMM of Baltimore purchased The Hearn-Morrill Cleaning Corporation, another Baltimore based company that was established in 1928. Hearn-Morrill specialized in residential window washing services and fire restoration and, with PMM of Baltimore, this organization could now provide its long standing customers, with expert carpet and floor cleaning services.
