Planning and permits
In general, any significant change to the exterior requires a formal building permit.
Make sure to clarify these points with your municipality before incurring any expenses or ordering materials, to ensure your energy renovation works are in full compliance with local urban planning rules.
Optimizing construction costs
The assembly and dismantling of scaffolding represent a significant share of the total cost of your facade project. An effective strategy is to bundle your renovation works.
If you plan to change your windows or perform repairs on your roof, it is highly recommended to plan these interventions simultaneously. This allows you to spread logistical costs over several services.
To better anticipate your overall budget, do not hesitate to use our RenoIndex tool to get a reliable estimate.
Subsidies and financial aid
It is advisable to regularly check the cantonal programs in force in the canton of St. Gallen, which may evolve over time. Always consult official websites to ensure the eligibility of your insulation project.
Quality of materials
The choice of insulation material impacts not only your home's thermal performance but also its durability and interior comfort. There are many options, from mineral wool to expanded polystyrene, with different characteristics.
Ensure you select certified solutions to guarantee optimal protection against weather and cold. An initial investment in high-quality materials is often paid back in the long run through increased energy savings.

Frequently asked questions
Do I need a permit for facade insulation?

When should I submit a grant application?
It is imperative to submit your grant application before work begins. Projects that have already started or are completed are not eligible for financial aid available in the canton of St. Gallen.
