Plumber in Delémont

Are you looking for a plumber in Delémont for a leak, a pipe replacement or a bathroom to redo? As the capital of the canton of Jura, the town combines an old town overlooked by its castle with newer districts set in the Birse and Sorne valley. This variety of buildings gives each plumbing job a different character, and that is what you need to describe in your request.

The most common plumbing jobs in Delémont

A sanitary installer (Swiss training: CFC, the federal certificate of competence, as a sanitary installer) looks after hot and cold water, drainage and fittings. In Delémont, requests generally fall into a few families:

• finding and repairing leaks: a stain on the neighbour’s ceiling, a meter that keeps turning while everything is off, damp in a cellar;
• replacing old pipes: galvanised steel that scales up and reduces flow and, in very old buildings, sometimes lead pipes;
• renewing sanitary fittings: washbasin, WC, shower, bath, taps;
• drainage: soil stacks, traps, slow or blocked outlets;
• hot water production: water heaters, connections, thermostatic mixers.

The choice between repairing and replacing depends on the overall condition of the installation. An isolated leak on a recent pipe can be dealt with on the spot; the same leak on an original pipe, in the middle of an ageing network, often points to other weak spots. The plumber can offer both options in the quote.

Old town, post-war blocks, newer districts: three scenarios

In Delémont’s old town, the buildings are old, the walls thick and access sometimes narrow. The pipes may have been altered several times over the decades, without reliable plans. A plumber who visits the site identifies the position of the risers, the possible routes and the places where a replacement would mean opening a wall or a floor. The old town is among the old towns of the canton named in the cantonal rules (with Porrentruy and Saint-Ursanne): before touching a visible element, a façade or a structure, you need to check with the municipality or the relevant cantonal department what is permitted.

In post-war blocks, common in towns of this size, the original installations are reaching the end of their life. Galvanised steel water risers, old drainage, worn taps: replacing a bathroom is often the opportunity to redo the pipes behind it as well. In this type of building, the riser serves several flats. Work on it therefore affects the neighbours above and below, and is coordinated with the managing agent.

In villas and houses in the newer districts, the issues are different: a simpler water network, but sometimes long pipe runs between the cellar and the upper floors, an external water supply, a garden tap, a plant room. The owner decides alone, which makes planning easier, but the quality of the making good of floors and walls still needs to be specified in the quote.

Jura winters, limescale and water: what the location changes for your pipes

The canton of Jura has cold, snowy winters. The Franches-Montagnes, at altitude, are the most exposed; the Delémont valley and Ajoie are milder. That does not remove the risk of frost in Delémont itself, especially for anything outside the heated volume:

• pipes in an unheated cellar or garage;
• pipes in an attic, an outbuilding or a little-used holiday home;
• outdoor taps and water supplies on the façade;
• corner rooms in old buildings, where the wall is poorly insulated.

If you are going away for several days in winter, draining a circuit or insulating exposed pipes is something to discuss with the tradesperson. After a frost, a leak may only appear at the thaw: it is better to have the installation checked before water comes through a ceiling.

Limescale is a second subject to deal with locally. Water hardness varies by region and network, and cannot be guessed: ask the municipality’s water supplier for the values. They affect the lifespan of water heaters, mixers and appliances, and guide the choice of any water treatment.

Finally, a town set in a valley crossed by the Birse and the Sorne is a reason to keep an eye on cellars and basements: damp that keeps returning is not always a pipe leak, and the plumber can help you tell a leak from external infiltration, before deciding which trade should step in.

Permits, landlord and co-ownership: who has to say yes?

Replacing a tap or repairing a leak does not in principle require any permit. As soon as the work changes the structure, the outside appearance or the use of the premises (a new shower room, moving risers, creating a drain), the question of a permit arises. In the canton of Jura, the building permit is issued by the municipality or by the canton depending on the size of the project: contact the municipality of Delémont to find out whether your project is affected.

If your work involves energy, for example hot water production linked to a new heating system, the cantonal energy section is the point of contact, and a cantonal subsidy programme exists. Its conditions, amounts and deadlines should not be assumed: find out before ordering, as some grants must be applied for before work starts.

On the housing side:

• villa owner: you decide, but keep a record of what is installed and where the pipes run;
• co-owner: shared risers and pipes are a matter for the co-ownership; the consent of the administrator or the assembly may be required;
• tenant: tell the managing agent or the landlord before any work, and obtain written consent for any change at your own expense.

Preparing your request and comparing quotes

The more precise the request, the more comparable the quotes will be. State:

1. the type of home (flat, villa, old town, post-war block) and the floor;
2. the problem you have noticed or the project, with photos of the fittings, the visible pipes and the meter;
3. the known age of the installation and the type of pipes if you know it;
4. access constraints (narrow stairs, courtyard, difficult parking);
5. your status (owner, co-owner, tenant) and any consent already obtained.

A good plumbing quote details the exact scope, the planned materials, labour, making-good work (tiling, painting, chases) and what is not included. The cost varies mainly with the accessibility of the pipes, their number, the quality of the fittings chosen, the extent of the making good and the need to coordinate other trades; it has no meaning without a visit or a precise description. Be wary of very short quotes that say nothing about materials.

Once your description is ready, you can request a quote, free and without obligation.
