Plumbing in Vieux-Carouge: low houses and inner courtyards

Vieux-Carouge was built in the 18th century under the Kings of Sardinia, with low houses, inner courtyards and a grid of streets. In buildings of this age, installations have often been altered in successive layers: a pipe redone in a kitchen, a bathroom added in a former storeroom, a drain connected somehow. The plumber therefore often starts by understanding what is already there before proposing anything.

The work most commonly found in this type of building:

  • finding and repairing leaks, sometimes hidden in a thick wall or under an old floor;
  • replacing old pipes, notably galvanised steel, and, in very old buildings, the question of possible lead pipes;
  • reworking drains, which clog or deteriorate with age;
  • installing or replacing a water heater;
  • creating or renovating a bathroom or kitchen in a small home.

The inner courtyards and narrow streets of the centre also affect how a job is organised: access for delivering a sanitary fitting, storing pipes or removing rubble should be planned in advance, and it is best to mention it in your request.

Pinchat and La Fontenette: more recent buildings, different needs

Around Pinchat and La Fontenette, the districts are more recent. There are more apartments in blocks, with shared risers, standardised bathrooms and installations from a different generation than those in the old centre. Requests there more often concern replacing a mixer tap, a WC, a washbasin or a water heater, or dealing with a leak between two floors.

In a building constructed after the war, pipes can reach the end of their life without anything showing: damp marks, uneven pressure, or water turning yellow after a period without use are signs to note for the quote. Tell the plumber: it changes the scope of the diagnosis.

Hard water and pipes: what Carouge means in practice

The canton of Geneva is very urban, on the lake, with mild winters on the plain and hot summers in the city. This has two practical consequences for plumbing.

First, frozen pipes are less of a concern there than at altitude. It is still worth protecting pipes in an unheated room, a cellar or an exposed courtyard, but it is not the central issue as it is in a mountain commune.

Second, limescale. Water hardness depends on the network supplying the building; to find out about your address, the surest way is to ask the commune’s water supplier. If the water is hard, it can affect the lifespan of a water heater, tap fittings or a washing machine, and guide the choice of appliances. The plumber can take it into account if given this information.

Tenant, owner, co-ownership: who decides in Carouge

Carouge has many rental buildings, and in Geneva many of them are managed by property managers (régies). In practice:

  • Tenant: work on pipes, risers or fixed appliances generally goes through the property manager or the owner. Report the problem in writing, keep a record and ask who is to appoint the tradesperson. For a renovation project of your own initiative, the landlord’s consent is required.
  • Owner of a house or apartment: you decide, but in condominium ownership (PPE), the common parts (risers, main drains, roof) fall under the co-ownership and its management.
  • Co-ownership: replacing a riser is discussed at the meeting and priced on the basis of a detailed quote.

Permits and energy: what to check with the canton

Building permits are issued by the canton, through the Office des autorisations de construire. Changing a tap or a fitting in a home does not generally require one; a heavier alteration, or any work affecting the structure, the façade or a protected building, may. As Vieux-Carouge and certain districts are protected, ask the commune or the relevant cantonal department for confirmation before starting.

On energy, the canton has a cantonal energy law (LEn) and a cantonal energy office (OCEN), on which the Buildings Programme subsidies in Geneva depend. If your plumbing project is linked to heating or hot water production, check with the OCEN what applies and on what conditions, before signing the quote rather than after.

Preparing your plumbing quote request in Carouge

A quote is only worth as much as the description that preceded it. To obtain comparable offers:

  1. Give the address or district, and the type of building: Vieux-Carouge house, rental building, villa, PPE building.
  2. Describe the problem with its signs: where the water appears, since when, whether the pressure has changed.
  3. State the approximate age of the installations, if you know it, and what you know about the pipes.
  4. Mention access constraints: narrow staircase, inner courtyard, no lift.
  5. Say whether you are a tenant, owner or co-owner, and whether the property manager or the administration has been informed.
  6. Attach a few photos; they avoid misunderstandings.

A good quote itemises the work: removal, supplies, fittings, labour, waste disposal, making good walls and floors, and states what is not included. The cost varies mainly with the condition of the pipes, ease of access, the number of water points, the quality of the fittings chosen and the extent of the making good. This is why a figure given without a visit or a description is of little value: only the quote gives a reliable one for your case.

When you are ready, you can request a quote in a few minutes; it is free and without obligation.

Frequently asked questions

Do I need the property manager's consent to call a plumber in Carouge?
If you are a tenant, work generally goes through the property manager (régie) or the owner, especially for pipes, water risers and sanitary fittings. Let them know before requesting any quote. For a simple urgent leak, report it to the property manager first, who will tell you what to do.
Can a plumber replace old pipes in Vieux-Carouge?
It is routine work in older buildings, where you may find galvanised steel, or even lead in very old constructions. As the district includes protected buildings, check with the commune or the canton before opening walls or touching façades and courtyards.
Is hard water an issue in Carouge?
Water hardness depends on the network supplying your building. To find out what applies at your address, contact the commune's water supplier. This information helps you choose a suitable water heater, tap fittings or water softener.
Does a bathroom renovation require a permit?
Simply replacing fittings inside a home generally does not require one, but this is not an absolute rule. If you change the façade, the structure or the use of the premises, building permits are issued by the canton of Geneva. Check with the commune or the relevant cantonal department.
What should a plumbing quote include?
It should describe the work item by item: removal, supplies, fittings, labour, and making good walls or floors. It should also state what is excluded. Comparing quotes based on the same description lets you see where the real differences lie.
