I was really getting frustrated with the office cleaning people in my building. Being a tenant, I didn't have the authority to fire them. After struggling with their ignoring all of my requests for three months, I finally went to the owners of the building and gave an ultimatum of my leaving if I couldn't get a different service. I looked on line for janitorial service Dallas and discovered wonderful comments about a company called Valor. I passed it on to the owners. They have been thanking me ever since. It feels like a brand new environment to work in since they took over.
