Swisskalk GmbH – Swiss Quality Since 1997

Based in Subingen, Swisskalk GmbH has specialized in water softening systems for over 27 years. Since the very beginning, we have pursued a clear goal: limescale-free water for all of Switzerland — reliable, durable, and backed by direct service.

Our new water softening system was developed and manufactured in Recherswil. This is a deliberate commitment to Swiss engineering, precise manufacturing, and short supply chains. The result is a system designed for long-lasting performance, delivered with a 10-year warranty.

Experience That Counts
With more than 25,000 installed systems in single- and multi-family homes as well as commercial properties, Swisskalk stands for reliability. Our systems prove their worth every day — reducing limescale buildup, minimizing cleaning effort, and providing optimal protection for appliances.

Everything From a Single Source
Swisskalk supports you throughout the entire lifespan of your system — from consultation to maintenance:

* Needs assessment and consultation based on your water hardness and installation conditions
* Professional installation by our in-house specialists — clean, precise, and on schedule
* Service and maintenance — regular performance checks and hygiene servicing
* Salt delivery directly to your cellar, including system refilling
* Boiler and hot water solutions tailored to your softening technology

With locations in Subingen (headquarters), Dübendorf, and Geneva, we serve customers throughout Switzerland.

Our Commitment
We rely on Swiss technology from Recherswil, professional workmanship, and direct customer relationships. This ensures that every system operates reliably for many years — and remains expertly maintained.
