Diagnosing moisture in the walls of a house

Noticing the humidity in the walls of a house is usually simple, but diagnosing the real cause often requires the intervention of a moisture professional. As far as drains are concerned, they are surface rainwater collectors after precipitation and cannot in any way solve the phenomenon of rising damp. They are outside the building and on the perimeter of the building, when the building has interior supporting walls, said to refend, there is never a drain, while these walls are affected like the others as well as the slab by the rising damp. If in doubt, and given that many professionals make a free diagnosis at home, feel free to call on them to determine with certainty the cause of moisture in the walls of your home.
