To find a reliable office cleaner, ask about experience, guarantees, references and customer service. Many companies prefer to hire professional cleaning services over full-time janitors.
Ask how long the company has been in the business and the criteria used for hiring cleaning staff. How long the cleaning service has been in business is often a good indication of the kind of service to expect. A cleaning service with an established reputation for quality service is likely to be reliable and professional.
Ask if the company guarantees its work before making a final decision to hire its services. Guarantees may include returning to the job site or offering a refund in case the services prove unsatisfactory. It is a good idea to get the price and scope of work in writing and compare this with the end results to assess the quality of the service.
A loyal client base is a good indication of a reliable office cleaner. Ask for references and contacting them for feedback to get a sense of what to expect from the cleaning service. References with similar office cleaning needs are preferred.
Lastly, ask if the company assigns a specific representative to the office account. A customer service representative familiar with the account is better placed to resolve issues or requests. Ask about the procedures for assessing, addressing and following up on issues or requests.
