About Unlimited Services

Unlimited Services Building Maintenance is a family-owned and operated company which first opened its doors in Tustin, CA in 1980.

Since 1980 Unlimited Services has kept its mission simple: to provide for customers the very best cleaning and maintenance professionals in the business along with levels of customer care not ever seen in the building service industry.

During our 37 years in business Unlimited Services has grown from one office in Orange County to three southern California regional offices in Santa Ana, San Diego, and Riverside. In 2005 we opened our Arizona regional office in Phoenix, Arizona.

Our approach to satisfying the needs of facility managers and owners revolutionized the industry when we began in 1980 and we have worked hard to remain ahead of our competition.

Today Unlimited Services works with hundreds of the very best cleaning and maintenance operators servicing over 2,000 facilities. And we keep growing.

"Typically, janitorial companies start out doing great and slowly start to slack since they know they have you locked into a contract. With USBM, everyday is like being a new customer with them. Randy and his team are always prompt, dependable, thorough and most importantly, "trustworthy". I would recommend Unlimited Services Building Maintenance to any business needing reliable efficient janitorial services. "
