Rising Damp vs Condensation: How to Tell the Difference
Damp patches and mould do not always have the same cause. Knowing the differences between condensation and rising damp can help you ask the right questions, but visual signs alone cannot confirm a diagnosis.

Condensation forms when moist indoor air meets cooler surfaces. You may notice water droplets on windows, mould around cold corners or recurring dampness in poorly ventilated rooms. Heating, airflow and humidity all play a part.
Signs sometimes associated with rising damp
Rising damp refers to moisture moving upwards through porous building materials. Low-level staining, salts and damaged plaster can be clues, but leaks and other moisture problems can look similar.
Why diagnosis matters
A new damp-proof course will not solve condensation, while simply wiping away mould will not fix water ingress. An assessment should consider the building and likely moisture sources before recommending work.
