If you are one such institution you have probably discovered that there are a lot of companies and it is tough to get good service at a fair price. To find a good cleaning contractor you should look at a variety of factors. Meet with the owner or the regional manger and determine how the company delivers quality. Ask how quality is measured, how often field supervisors examine buildings, how supervisors are hired and trained, and if the on-site manger or supervisor is experienced. In other words, make the company validate the promotional materials they give you.
Training is another key element and it can make the difference between a good, or bad, experience.
Off-site training not only provides a better learning environment, but it also avoids costly damage to your collection or building. Also, ensure that the cleaning company provides staff training suitable to your needs. Check to satisfy yourself that the company is complying with federal laws regarding training in issues like hazards communication and bloodborne pathogens. Unfortunately, for most institutions price is often the only issue looked at. Be sure, however, that the price includes items like liability insurance and workers compensation insurance.
