Have had personal experiences with their employees and all seems like a great group of people who care about the end product.

I have used Certified Maintenance Service (CMS) and had an excellent experience with their organization. Their employees were very well organized and thorough in cleaning our facility. Our customers spent a lot time in our building, so it was very important our facility was clean and sanitary. CMS did a great job in providing a clean environment for our customers and our employees. In addition, CMS’ office staff did an excellent job in providing accurate billing, supply management, and our Account Executive provided excellent customer service.
