Gradd Hy Janitorial Service

HyGrade Janitorial Services LLC was established in 1984. We operated out of Waterbury for 17 years until we moved to our new location in Wolcott. The business started out as a family operated business. All work was performed by owners Joseph and Isabel Ribeiro and other members of the family. However, due to the success of the business, the company grew to the point of having to hire new employees from outside the family.
