Check the insurances


To protect you, the craftsman must take out a “damage and construction” insurance policy, which is complementary to the ten-year guarantee. This guarantee covers the cost of work carried out during the ten-year guarantee period. Moreover, the professional must also subscribe to certain insurances such as:

    • A professional liability insurance
    • Multi-risk home insurance protects against certain unforeseen events, such as fire or water damage.

Do not hesitate to ask for a copy of the insurance contract and to verify that the insurer is well-recognized on the market. Don’t forget to look at the validity period and if in doubt, contact the insurance company.
