Maintenance Service Systems

MSSI started in 1951 as a small, family-owned business. Today, it is still owned and operated by the same family, but has grown into the largest commercial janitorial service company in New Mexico with more than 5,000,000 square feet under contract. From commercial office buildings and high-tech facilities to government institutions and schools, MSSI customizes service programs to fit your needs. Our management and support staff work diligently to deliver quality cleaning services and ensure 100% customer satisfaction.
