I am about to buy a house built in 1975. On this house there are several horizontal cracks on the exterior facades and the ceiling in some rooms that have been blocked by the owner. The house is in Brittany. Do I have to worry and what should I do?

The presence of mostly horizontal cracks is never a good sign. They often reveal a weakening of the structure. Before any purchase, you should know the origin of these cracks and involve an expert to have his opinion to determine the possible gravity of the situation and thus avoid big disappointments in the future.
