There have been some spots appearing on the exterior facade of the house in certain areas over the past few weeks, which I cannot identify. They only occur in one section of the house, and I am wondering what the causes might be. Are the causes coming from outside or inside? Could it simply be weather-related changes, or possibly a moisture problem from the inside?
Maybe someone here can help me and knows the cause.
I have attached a few pictures that might be helpful for the assessment.
Thank you very much in advance for your support.
Regards,
