Are you looking for a plumber in Nyon for a leak, a bathroom to redo or ageing pipework? A town on La Côte, on the shores of Lake Geneva between Geneva and Lausanne, Nyon combines an old centre, apartment blocks and villas: so many situations where water work differs. This page helps you describe your needs and prepare a quote request to plumbing firms in the area.

The most common plumbing work in Nyon

The plumber’s trade, or sanitary installer (the corresponding Swiss qualification is the CFC, the federal vocational certificate, for sanitary installers), covers a wide range of jobs:

  • installing or renovating cold and hot water supplies;
  • waste water drainage, from washbasins to building stacks;
  • replacing sanitary fixtures: WC, washbasin, bath, shower, taps;
  • finding and repairing leaks, whether visible or hidden;
  • replacing old pipes, made of galvanised steel or, in very old buildings, lead.

In Nyon, this work takes different forms depending on where you live. In a flat in a post-war block, the most frequent request concerns the bathroom or kitchen: replacing an old mixer tap, fixing a poorly draining waste pipe, swapping a bath for a shower. In a villa on the higher ground, it is more often a question of redoing the whole network, adding a shower room or creating a connection for an extension.

Old town and castle: plumbing in old buildings in Nyon

Nyon’s castle and old town occupy a hill above the harbour. This town founded by the Romans has kept an old built fabric, with buildings with thick walls, vaulted cellars and floors that have been fitted out over the centuries. For a plumber, this changes several things.

First, the routing of pipes. In a thick wall or under an old floor, you cannot drill just anywhere: existing routes have to be located, sometimes ducts that have been altered several times, and a decision made whether to reuse the old route or create a new passage. Then there is the age of the installations: a very old building may contain galvanised steel pipes, sometimes lead. Replacement is then a matter of health and durability, and it is better to ask the firm what it finds on site rather than rely on an estimate made from a distance.

Finally, access. The lanes of the old town and the slope down to the harbour complicate the delivery of materials: bulky fixtures, water heaters, rubble. Mention this in your request, so that the quote takes account of carrying and parking.

Rental blocks, villas and hillsides: what Nyon’s buildings change

Nyon stretches from the lakeshore up the hillsides, in a landscape of gentle slopes typical of La Côte. You will find rental blocks from several periods, including post-war developments, and villas with gardens. Each type of home has its own logic.

Rental blocks. Water and waste stacks are shared by several flats. A repair in your home can therefore affect a neighbouring floor, and the work usually goes through the managing agent or the landlord. A leak in your bathroom ceiling may come from the flat above: a written report to the managing agent remains the right reflex.

Villas. The owner decides alone, but also manages everything: internal network, any external connections, technical room. Buried pipes between the street and the house, or between two buildings, deserve particular attention if you notice a drop in pressure or unexplained damp on the ground.

Slopes and drainage. On sloping plots, drainage has to be planned with the terrain. If you are creating a shower room in the basement, ask the plumber how drainage will be provided, by gravity or by a lifting pump.

Limescale, frost and the climate on the shores of Lake Geneva

The climate on the shores of Lake Geneva is mild, which in principle limits the risk of frost compared with the Jura or the Vaud Alps, where snow settles. An unheated room, a garage, a cellar or an outdoor pipe can nonetheless remain exposed during a cold spell. If you own a chalet or a second home at altitude, say so: protecting pipes against frost there calls for quite different precautions.

Water hardness depends on the network. Limescale clogs water heaters, mixer taps and shower heads, and explains many calls about dripping taps or falling flow rates. To find out about the quality of the water supplied in your neighbourhood, contact the municipal water supplier. With this information, you can ask the plumber about water treatment or regular maintenance.

Much routine plumbing work, such as changing a tap or a WC, requires no particular procedure. Things change as soon as the project alters the building or its installations in a more visible way.

  • Building permit. It is issued by the municipality. When cantonal services need to give an opinion, the file goes through the cantonal permits office (CAMAC). Ask the City of Nyon’s services whether your project is subject to it.
  • Energy. If your work affects hot water production or heating, the Vaud energy law and the cantonal energy directorate are worth knowing about. A cantonal subsidy programme exists: check it with the competent cantonal service before signing, as the conditions need to be verified beforehand.
  • Protected buildings. Within the old town perimeter, work visible from outside or affecting the fabric of the building may be regulated. Again, the municipality or the competent cantonal service will tell you what applies.
  • Tenants. No alteration without the landlord’s consent. The simplest approach is to write to them describing the work and attaching the quote.
  • Co-ownerships. Stacks, common areas and sometimes façades belong to the community of owners. Check the regulations and the assembly’s approval before ordering.

Preparing your request and comparing quotes

The more precise the request, the more comparable the quotes will be. Before writing, gather:

  1. the address or at least the neighbourhood, and the type of home: flat, villa, old building;
  2. a clear description of the problem or project, with photos of the fixtures, visible connections and signs of damp;
  3. the approximate age of the building and what you know about the pipes;
  4. your status: owner, tenant (with the landlord’s consent) or co-owner;
  5. your constraints: access, times when you are present, work to be coordinated with other trades.

A good quote itemises the work: removal of what exists, supply, installation, connections, making good the surfaces that were opened up, waste disposal. Ask what is included and what is not, in particular tiling or painting work after a wall has been opened. If partitions need to be opened, the firm may not know in advance what it will find: ask how unforeseen items will be handled.

The cost varies according to several factors: accessibility of the pipes, age and condition of the installation, choice of fixtures, number of water points, extent of making good. That is why no figure can be given without seeing your situation. Compare several proposals on the same basis, without stopping at the total alone.

Frequently asked questions

Do I need a building permit to replace a bathroom or pipework in Nyon?
It depends on the scale of the work. Simply replacing a fixture or a pipe like for like does not carry the same requirements as an alteration affecting the façade, the structure or a protected building. The building permit is issued by the municipality: check with the City of Nyon's services before you start.
I rent in Nyon and have a leak: who calls the plumber?
In a rental block, the work usually goes through the managing agent or the landlord. Report the leak in writing, describe it and attach photos, then ask who will instruct the contractor. Do not call someone in on your own initiative without speaking to the landlord first.
Do the pipes in an old building in the old town need replacing?
Very old buildings may still have galvanised steel pipes, or even lead ones. Only an inspection on site will tell you what you have. The plumber can tell you what justifies a replacement, partial or complete, and what getting access to walls and floors involves.
Is the water in Nyon hard?
Water hardness varies by region and by network. For reliable data on your neighbourhood, contact the municipal water supplier. This information helps you choose a water softener or descaling, and to discuss the maintenance of water heaters and taps.
What should a plumbing quote include?
It should describe the work item by item: removal, supply of fixtures and pipes, installation, connections, making good the surfaces that were opened up. Also check what is included for disposing of the old components and what remains the responsibility of another trade.
