To find the best commercial cleaning company, understand your requirements. Know the degree of cleaning your office space needs and consult with experts to learn about the costs. Then, you can move along with the following tips. 

1. Conduct interviews: Cleaning a commercial space differs from cleaning a residential property. Therefore, make sure that your first interview with the commercial cleaning team is. 
2. Get reference: When cleaning, you only want trusted workers to enter your office. Therefore, make sure that those who reach out to you have referrals. 
3. Check out online reviews: Most commercial cleaners have become tech-savvy and are running online businesses. So, read reviews about them before starting an interview. 
4. Ask for liability insurance: Offices are filled with computers and other critical IT assets. Haphazard cleaning can damage them. So, before hiring commercial cleaners, ask them if they have liability insurance. 
5. Only hire licensed cleaners: In a bid to cut costs, some businesses just hire anyone to do their cleaning. Do not gravitate towards that – make sure to hire licensed cleaners. 
6. Assess the cleaning process: Commercial cleaning has several layers to it, each deeper than the other, to ensure that your office is not only clean but also disinfected. That can only happen if there is a good cleaning process in place. So, assess the cleaning process before getting started.
