One important decision that many owners and managers of commercial buildings face is whether to hire their own staff to keep the buildings clean, or to contract office cleaning services. Contracting a cleaning service is usually more cost effective and reduces liability and personnel issues associated with having cleaners on the payroll. The question then becomes which cleaning service to choose.

A building manager must compare the rates quoted by competing cleaning services, as well as the length and type of experience each of them offers. A cleaning service that has been in business for decades has outlasted less efficient competitors and has knowledge of many different types of situations that may arise. Such a firm will probably have an impressive client list and be able to offer references from satisfied customers. They will have staff that is familiar with many different types of floor surfaces and be able to treat them appropriately. They may have staff that has experience with specialized cleaning situations, such as medical facilities.

Reputable office cleaning services should be able to present certifications. An important certification is LEED, or Leadership in Energy and Environmental Design, developed by the USGBC, or United States Green Building Council. A cleaning service with LEED certification has demonstrated that it meets standards for environmentally friendly operations. This means that those who work in commercial buildings will not be exposed to toxic substances. Operating in an environmentally friendly fashion usually means operating efficiently and with an eye to detail, two important considerations when choosing a cleaning service.
