SANJOSE has a policy of providing high quality work; quality in the materials used, completed projects, excellent services, and everything needed to completely satisfy the client.
The Group has incorporated the philosophy of Total Quality, which implies the involvement of all its members, and the Quality Management System, based on the UNE-EN ISO 9001 standard.
The methods used to achieve this quality range from program coordination and supervision of the management systems to continual training in the area of quality. And, of course, they include the constant verification of the system, information, monitoring, and auditing of errors, as well as the specific definition of all the procedures that ensure quality in the final product (Manual of Procedures).
