Dominic Chinea was born in the United Kingdom, though his exact date of birth is not publicly confirmed. He celebrates his birthday on 4 May and is believed to be in his 30s.

He studied graphic design at South East Essex College, where he developed creative and technical skills that later shaped his career. He went on to work as a set designer and prop maker, collaborating with studios such as Rankin Studios on editorial shoots and music videos.

Chinea joined The Repair Shop in 2017 on BBC Two (later BBC One), where he works as a metal specialist restoring items of historical and sentimental value. He later became co-presenter of the spin-off The Repair Shop: On the Road, launched in 2025 on BBC One.

Chinea lives in Kent with his wife and their dog, maintaining a relatively private personal life while continuing his TV and design work.
