Plumbing on the Côte d'Azur: what to expect and what to ask

When you call matters most. Evenings, weekends and public holidays carry a surcharge, so ask what it is before the plumber starts. If you can stop a leak by closing the main stopcock, the repair can often wait for normal hours.

Finding the leak can cost more than fixing it. A pipe behind tiles or under a floor has to be opened up, and putting the tiles back is a second job. Ask whether the price covers making good or only the plumbing. Old galvanised pipe often can't be patched either, so a single repair can turn into replacing a whole section.

Ask whose pipe it is before anyone digs. A leak before the water meter is the water company's to fix, as the section below explains. In a flat, a leak on the building's shared riser is usually the responsibility of the copropriété (the building's co-ownership), so call the syndic (the building's managing agent) first.

Before work starts, get the call-out fee, the hourly rate, any surcharge and the parts written on the devis. The first hour is usually charged in full, however short the visit. For anything that isn't an emergency, get two written quotes.

Water on this coast is hard, in Cannes and Nice as elsewhere. Calcaire (limescale) is the mineral residue that comes out of that water. It builds up inside pipes, on tap valves and above all on the heating element inside a water heater.

Pipes narrow and appliances work harder, sooner than the manufacturer assumes. In an older Riviera property with galvanised pipe, have the pipework checked before you assume it only needs patching. Corrosion and scale build up together, and one often hides the other. If you need a new water heater, our hot water systems guide covers service intervals and what calcaire does to them. Ask the plumber whether a softener or a scale inhibitor makes sense for your property. It isn't always worth it on a part-time second home, but it's a fair question to raise.

A plumbing devis shows the same basics as any French quote. That means the company's name and registration number (SIRET), a description of the work and the parts. It also shows the TVA (French VAT) rate and the totals before and after tax (HT and TTC). The décennale (ten-year building insurance) insurer and policy number belong on it whatever the size of the job. Waterproofing and pipework built into the structure fall under the ten-year décennale, which runs from the handover (réception des travaux). A tap or water heater swapped into an existing home gets neither the biennale nor the décennale since a 2024 Cour de cassation ruling. Ask for the fitter's warranty on the fitting and the maker's warranty in writing.

If the job isn't urgent, ask for a start date. Get any add-on the plumber suggests on site written into the devis before they leave.
