Its service portfolio covers the complete renovation of cast iron radiators: diagnosis and leak testing, aérogommage and dimension-accurate sandblasting, sludge removal (désembouage), repair and welding of defective elements, as well as painting and coating with heat-resistant, made-in-France paints free of toxic emissions. The company also restores historic cast iron radiators (styles such as Rococo, Belle Époque, Art Déco, Art Nouveau) and offers renovated radiators for sale. In its own foundry, caps, return valves, feet and wood stoves are produced from recycled cast iron scrap. Logistics (collection and return transport) are handled with its own fleet without subcontractors; a 10-year warranty is given on renovated radiators. From January 2027, the company will transform into a matchmaking platform connecting tradespeople and private individuals for the renovation of cast iron radiators.
