JANS groupe

The JANS groupe has been operating for more than 25 years and is (now) run by the second generation.

JANS constructions

The demand for detached houses, regardless of whether large, small, modern or traditional, has steadily risen over the last few years. The JANS groupe fulfills individual home-ownership dreams from one single provider. We work closely with our clients to find the perfect property and plan your dream home from construction of the foundation slab through to the handover of the keys. Our clients value top quality and good customer service. Increasing incoming orders led to the company’s continual growth and in order to offer even better service, JANS immobilière was established.

JANS toitures

A well-built house is above all a perfectly insulated house. A badly-built roof leads to unnecessary energy consumption. Waterproofing and insulation problems that are accentuated by climate changes (rain, wind, snow, frost), have long-term negative effects on the home and general wellbeing. A roof must therefore be in perfect condition to ensure optimum protection throughout the entire year.
