Subcontracting exhaust cleaning work

I received a call a week ago from a new company trying to clean nationally. They wanted us to do some work for them, but they did not want our hood stickers used, only theirs. I refused as always. They also said they are following up with pictures. We just inspected their work in the Midwest in another area and I wonder where the pictures are coming from as you can see the old buildup in the attached picture they are not paying much attention. This is very typical from what I have been seeing from almost all the companies who are subcontracting their work around the country. Many pictures in this blog are from some of those companies. I do not believe in sub-contracting cleanings and we never will subcontract work ourselves. Cleaning companies need to do their own work with their own employees as grease exhaust fires are to damaging and costly to leave to others.  I think there is no way a customer can get their moneys worth and most simply sub out to the lowest contractor so often restaurants end up with companies they had previously fired or would not normally use. It is also my opinion is that cleaning companies are fools to do this sub-contracting work for many reasons. I will post these in an article I am currently writing along with my Southern Regional Manager. I have been contacted many times in the past about this and have been burned badly many years ago so I speak from experience. We have refused all sub-contracting work since that time when I looked into it and realized how bad of a value it was for the restaurants and how it reflected on our company to be associated with these companies.
