Insurance to require
- General liability, with a certificate naming your company as certificate holder
- Workers compensation covering every person who enters your building
- Where the contract calls for it, a fidelity or crime bond covering theft by cleaning staff
- Auto liability if company vehicles are on your property
Training for medical offices
Crews that clean exam rooms, procedure rooms, and clinical restrooms should have OSHA bloodborne pathogen training (29 CFR 1910.1030) and hazard communication training on the disinfectants they use. Ask for the written disinfection protocol: which EPA-registered products, on which surfaces, at what dwell time. A vendor that cannot produce that document has not built one.
Requirements for schools
Schools should require criminal background checks for every person on site, a product list appropriate for use around children, and a scope that names high-touch surfaces (desks, door hardware, drinking fountains, restroom fixtures) with frequency. Ask how the vendor handles illness season and how quickly frequency can increase.
Voluntary certifications
ISSA CIMS (Cleaning Industry Management Standard) and Green Seal certifications are voluntary programs that signal management systems and product standards. They are useful signals, not substitutes for insurance, training records, and references. Many long-tenured local companies deliver a high standard without them.
What to ask for in writing
- Certificate of insurance
- Training records or certificates for bloodborne pathogen and hazard communication
- Background check policy
- Written disinfection protocol and product list
- Scope of work by area and frequency
