What to do if I notice cracks on my house?

Cracks in buildings can cause concern, but their severity varies. Some are superficial, while others may compromise structural integrity. Insurance coverage is possible if the origin of the cracks is identified, requiring documentation of their appearance and progression. If the construction was completed within ten years and the issues threaten the structure, the builder's ten-year warranty can be invoked. Climate change has increased cracks due to soil shrinkage and swelling, affecting millions of homes. Homeowners may claim compensation under natural disaster insurance, but the process can be lengthy, requiring municipalities to declare a disaster within 24 months. Since 2024, only damages affecting structural integrity are compensated, excluding aesthetic issues, with a deductible of 1,520 euros.
