Why Rising Damp Is Commonly Misdiagnosed
Rising damp is one of the most frequently misdiagnosed damp problems within residential properties. Visible low-level damp symptoms are often assumed to indicate rising damp without sufficient investigation. An independent damp survey identifies whether rising damp is genuinely present or if alternative causes are responsible.
What Rising Damp Actually Is
True rising damp occurs when moisture from the ground travels upward through porous masonry by capillary action. It typically presents as a consistent pattern of moisture rising from ground level, often accompanied by salt contamination. Rising damp is relatively uncommon compared to other causes of damp.
Why Rising Damp Is Often Diagnosed Incorrectly
Rising damp is commonly diagnosed based on surface symptoms and moisture meter readings alone. Damp staining, peeling paint, and elevated readings at low level can occur for many reasons. Without a full assessment, these symptoms are frequently attributed to rising damp incorrectly.
Common Issues Mistaken for Rising Damp
Several damp problems can produce symptoms similar to rising damp. Condensation can cause low-level moisture due to cold surfaces. Penetrating damp may lead to localised moisture following rainfall. Historic salt contamination within plaster can also generate false moisture readings.
Why Moisture Meters Can Be Misleading
Moisture meters measure electrical resistance rather than free moisture. Materials contaminated with salts or exposed to high humidity can produce elevated readings even when no active moisture movement is present. Relying solely on meter readings often leads to incorrect rising damp diagnoses.
How Independent Damp Surveys Prevent Misdiagnosis
Independent damp surveys assess the full range of potential causes before reaching conclusions. This includes evaluating moisture patterns, external building conditions, internal environment, and historic materials. Rising damp is only diagnosed when alternative explanations have been eliminated.
