People often don’t replaster both sides of the wall after rising damp is fixed, but that may be the reason that the damp patch returns.
This is because natural salts that have traveled up from the soil may still be present in the plaster, drawing in moisture like a magnet.
For a survey to determine whether it’s the salts in your walls drawing in condensation, or a rising damp problem, you can book a survey with our team online.
