About us

A new generation, the same way of working

Marin57 grew out of a family trade in installations spanning two generations. After more than 15 years in the trade, we have taken the step of starting our own business to carry on that path, keeping the experience, the know-how and the trust of the clients who have been with us for years.

Today we still work with the same philosophy: a close, personal service, professional advice and special attention to every detail, from a small installation to a full renovation.
