Samuel L. Flagg, Sr., president of Clean Master Services, Inc. started the company in 1979. Mr. Flagg has worked in the janitorial industry well over 30 years.  


With just an entrepreneurial drive, my old Toyota wagon, and a mop and bucket, Clean Masters Services, Inc. was established. The company provides commercial janitorial cleaning throughout Jacksonville, FL.  From the beginning, Mr. Flagg wanted to establish a company that focused on ensuring their clients received quality service by well-trained and dependable employees

Clean Master Services is determined to grow our business relationships through our commitment to provide consistent and outstanding building maintenance services. This philosophy is epitomized by our corporate guarantee, mission statement and company motto:

Warm Regards,
