Recognised technical expertise,
based in Monaco for over 30 years.

HMC is a team of professionals serving individuals and businesses for the design, delivery and maintenance of electrical, plumbing, heating, sanitary, air conditioning, renewable energy and water treatment systems.

On 1 January 2026, HMC merged with Monte-Carlo Rénovation. This union extends our scope to renovation works — masonry, tiling, marble, painting, joinery — and allows us to run a project from start to finish, from structural work to final finishes, with a single point of contact.

Our expertise is kept sharp through regular training and constant monitoring of technological developments — the guarantee of the quality of our work.
