Your project in the canton of Valais
Valais follows the Rhône valley from Brig to Lake Geneva, with side valleys climbing up to mountain resorts. The canton is bilingual: French-speaking Lower Valais, around Sion, Martigny and Monthey, and German-speaking Upper Valais, with Brig and Visp. On the hillsides, vineyards surround villages of stone houses and old wooden granaries. Crans-Montana and Zermatt are home to chalets, holiday flats and hotels; in Zermatt, where cars are not allowed, transporting materials requires special arrangements. At altitude, snow and sunshine influence building techniques and the working season. Wherever you live in Valais, you can write your request in English. For a chalet, a traditional mazot or an alteration in an old town, check with your municipality whether approval is needed. Give the municipality and postcode and, in a resort or at altitude, access periods and transport arrangements to the building.
- For a chalet in a resort, note the altitude, the state of the road in winter and your availability for the work.
- In Upper Valais, say whether you are happy to communicate in German.
- For a village house among the vineyards, describe access via the lanes and the space for unloading materials.
Insulation work in the canton of Valais
In Valais, the contrasting climates of the Rhône plain and the mountain resorts guide insulation choices. In Sion, Martigny and Monthey, condominium buildings and villas in residential districts are having façades and roofs insulated, to protect against both winter cold and intense summer heat. In Crans-Montana and Zermatt, holiday homes need a high-performance envelope against frost, snow and strong sunshine. In Upper Valais, towards Brig and Visp, old larch houses and converted granaries are renovated with respect for the wood. For a small storehouse, granary or old chalet, consult your Valais municipality.
- In a converted granary, insulate from the inside with a flexible material that follows the irregularities of the logs.
- In a resort, book the work early in spring, as companies are in high demand during the short season without snow.

Frequently asked questions
What information should I send for an insulation project in Valais?
State the type of building, its age and which parts you want to insulate, such as the roof, walls or floor. Add photos and, if available, an energy report or plans of the house. This helps the company assess the options and plan a visit.
Why should moisture be assessed before insulation is added?
Existing dampness, air leakage and the proposed layer arrangement affect how an insulated construction behaves. Covering a problem does not establish its cause. Ask for an assessment of the relevant building element and the treatment of joints, ventilation and moisture before work proceeds.
What should I compare in insulation specialist quotes?
Compare the insulated area, material, thickness and treatment of interfaces. Clarify removal of existing finishes, scaffolding and reinstatement. Ask how windows, services or adjoining construction are handled, and which supporting assessment or documentation is included for the proposed system.
How should I prepare for the insulation specialist visit or work?
Gather available plans, energy reports and photographs of damp or damaged areas. Explain which rooms remain occupied and whether external access is restricted. Do not remove suspect old materials yourself; agree any inspection and preparatory work before insulation is installed.
