Diastone is a company that specializes in professional services for the treatment, polishing and technical maintenance of stone, other surfaces, and architectural elements. We have over 29 years of experience, and we work with state-of-the-art and exclusive technical methodologies. This allows us to guarantee the maximum quality, efficiency and customer satisfaction in every project. All this without giving up an accessible and dynamic approach, which is the result of our company being a family owned and operated business, founded by Jacint Castells in 1996.
We employ a highly specialized staff made of dedicated work groups for each project and service type. When needed, we can provide you with permanent staff at your facilities for maintenance tasks tailored to your needs. All our staff is perfectly identified with Diastone’s corporate clothing and vehicles.
Remember, we do not subcontract, we offer a service without middlemen, to guarantee you a professional and competitive service every time. We are at your disposal.
