Plumber in Paris: what to know
Most Parisians live in apartment buildings, many of them Haussmann-era blocks from the second half of the 19th century with shared risers, old cast iron or lead pipes and narrow service ducts. A leak in one flat quickly becomes a water damage case for the neighbours below, handled between insurers with a joint report (constat amiable dégât des eaux). Paris water is hard, so limescale builds up in water heaters (cumulus), taps and toilets.
Many flats have electric hot water tanks rather than gas boilers. Plumbers must hold a recognised qualification or proven experience, and a written quote is mandatory before any repair over 150 euro including VAT.
Paris attracts many international residents, and you can ask for a tradesperson able to communicate in English.
