There are three common types of damp you might encounter:
Rising Damp – moisture rising through walls from the ground due to a failed or missing DPC.
Penetrating Damp – water entering from external sources such as leaks, porous brickwork, or defective gutters.
Condensation – caused by excess moisture in the air condensing on cold surfaces, often in kitchens or bathrooms.
Each type requires a different treatment approach, which is why a professional survey is essential.
