About us
Recognised technical expertise,
based in Monaco for over 30 years.
HMC is a team of professionals serving individuals, businesses, the Monegasque State and the Domaines administration (state property) 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, pool — and allows us to run a complete project 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.
