Clarify the canton first, then building cover.
In many cantons, mandatory cover is regulated by the canton and provider choice is restricted. A generic price comparison falls short here.
Create your profile and get suggested insurance areas before starting a check.
No blanket free choice of provider
For fire and natural hazard risks, cantonal or private solutions exist depending on location. Mandatory insurance, responsibilities and exceptions must be clarified locally. A cantonal mandatory insurance is not interchangeable like a freely chosen policy.
Review supplementary risks separately
Tap water, glass, earthquake and other risks are not automatically part of every basic cover. Which additions are necessary or possible depends on the building, canton and contract.
Building value is not an online estimate
Use existing valuations and documents for a later expert review. The local questionnaire estimates neither the reinstatement value nor the premium.
