Plumber in Fontenay-sous-Bois

Between the Bois de Vincennes and the plateau, Fontenay-sous-Bois mixes streets of detached houses, older buildings in the town centre and large housing estates. Our plumbers work there 7 days a week, 24 hours a day, in houses and flats alike.

Leak detection in Fontenay-sous-Bois

In a house, a leak can stay hidden for a long time: a buried pipe between the meter pit and the house, a pipe set into a concrete slab, a basement that never dries out. The best first test is simple: close every tap and check whether the meter is still turning. In a flat, a ring on the ceiling or a damp service duct often points to a leak at a neighbour's or on a riser. Our leak detection and repair service locates the leak before opening anything up, then fixes it.

Blocked toilet and drain unblocking in Fontenay-sous-Bois

In houses, a toilet that keeps blocking often points to the outdoor drain: a clogged inspection chamber, roots, not enough fall. In apartment buildings, if water comes back up in the shower or sink, the shared stack is the problem. Our drain unblocking service clears toilets and pipes, including buried drains and inspection chambers.

Housing and plumbing in Fontenay-sous-Bois

Older houses often have plumbing altered by each owner, with joints between different materials and ageing drains. In the large estates, the original risers and waste stacks are the weak point: corrosion, worn joints, repeated blockages on the lower floors.

Tap water in Fontenay-sous-Bois

Fontenay-sous-Bois is a member of SEDIF, the Île-de-France water syndicate, and water is distributed by Franciliane (Veolia). The 14 official tests published between January and July 2026 show hardness from 23.6 to 35.7 °f (French degrees), with a median of 28.9 °f: one of the hardest waters among the towns we cover most often. Descaling the water heater and taps really matters here.
