Accredited Building Services has done the janitorial services at our company for a number of years. All of the cleaning people are employed by ABS (not sub-contract). They are very honest and cooperative people who are proud of their work. After having a different janitorial service every year for thirteen years, it is a joy to have a service that is completely reliable and trustworthy. I heartily recommend ABS janitorial service to anyone wanting one less headache to contend with.
