Why plumbing in Switzerland is about regulations and water quality

In Switzerland, water supply is regulated just as strictly as electrical work. Drinking water quality and the design of internal systems are governed by the SVGW/SSIGE (W3) directives and the SIA 385 standards. These texts set out requirements for pipe materials, backflow protection, hot water temperature and the prevention of legionella — a bacterium that thrives in stagnant warm water and poses a real health risk.

For a homeowner, this means something simple: plumbing isn't just about getting water to flow, but doing so safely. Poorly chosen materials, missing backflow protection or an incorrectly set water heater can degrade drinking water quality. That's why the work should be done by a professional who understands not only the mechanics but also the sanitary requirements of the Swiss standard.

The plumbing services we provide in Geneva and Lausanne

SmartHaus Swiss covers the full spectrum of needs for owners of apartments, houses and commercial premises.

Pipework installation and replacement

We install and replace cold and hot water pipework as well as drainage systems. We select materials (press fittings, multilayer pipes, stainless steel) to suit the property, and calculate diameters and gradients. We work both in new builds and on replacing old, worn-out plumbing in the historic housing stock of Geneva and Lausanne.

Sanitary fixture installation and repair

We install and replace taps, basins, toilets, bidets, showers and bathtubs. We connect washing machines and dishwashers. We fix leaks, replace worn seals, repair flush mechanisms and clear blockages — quickly and without unnecessary mess.

Water heaters and boilers

We install, replace and service storage and instantaneous water heaters. We carry out maintenance and descaling of boilers, which extends equipment life and maintains a safe water temperature. A properly set water heater means both energy savings and protection against legionella.

Hot water supply systems

We design and install hot water systems with circulation, ensuring hot water reaches the taps quickly. This improves comfort and reduces water and energy use, since there's no need to run off cooled water while waiting for it to heat up.

Emergency repairs and leak fixing

We respond to urgent situations: leaks, burst pipes, blockages. We locate the problem, address the cause rather than just the symptom, and restore the system to working order. In the apartment buildings of Geneva and Lausanne, a fast response is especially important to avoid damage to the neighbours below.

How working with SmartHaus Swiss works

The process is transparent and predictable. We visit the site or discuss the task remotely, then prepare a clear quote with no hidden charges. Once approved, we carry out the work within the agreed timeframe and leave the site clean. All work is guaranteed.

We treat your home with care: we protect surfaces, clean up after ourselves and work to cause as little disruption as possible. This matters especially when renovating an occupied apartment, where water is needed every day.

How much plumbing work costs in Geneva and Lausanne

The cost depends on the nature of the work, the accessibility of the pipework and the condition of the existing system. Replacing a tap and re-piping an entire house are tasks of completely different scale. That's why we always assess the specific situation first and only then quote an honest price. This approach avoids nasty surprises on the bill and helps you plan your budget in advance.

Our specialists understand the SVGW and SIA requirements, speak your language and know the specifics of French-speaking Swiss property — from modern apartments to older buildings in the centre.
