When it comes to the cleaning industry, there is a clear differentiation between consumer based cleaning and commercial cleaning. Consumer cleaning is made up of services of a maid, carpet and window cleaning. Here the services are required intermittently. Commercial cleaning is largely about janitorial services and besides the regular consumer needs include carpet and window cleaning on a larger scale. This is really essential for a commercial set up because you need to spend your time building up a business rather than worrying about nitty-grittys. Also a clean office is something that leaves a lasting impression on potential clients and investors.
Depending on the kind of business you own, you can look for niche commercial cleaning services. Such services will be better able to serve your company as they have particular tools and cleaning equipment that is specific to your industry. You can choose such niche cleaning services that service a limited clientele or you could chose more general services that have several clients as well.
Commercial cleaning services are also segregated into franchise as well as independent services. You can choose to go with a franchise since the contract you get into may be well defined. The services will be niche and the contract guaranteed. In the case that your regular cleaning crew doesn't make it, the franchise will ensure that you have a replacement sent at the same time. Also the franchise takes the trouble to investigate each of their staff's background so you don't have to worry about strangers in your office.
This is not to say independent commercial cleaning services are not good. Go by recommendation and word of mouth. Make sure to check the credentials of the service as well experience they have had in your business field. The advantage with independent commercial cleaning services is that you can expect a bit of flexibility in terms of the contract and can even tailor it to suit your needs.
