Rising Damp:
With the exception of subsidence, the term “rising damp” in a survey report is one of the main triggers likely to set alarm bells ringing with potential purchasers and mortgage lenders.
The Reality of “Rising Damp”:
However, true cases of rising dampness are relatively uncommon and require careful consideration. Rising damp is caused by the upward passage of moisture through the wall via capillary action. Its occurrence depends on factors such as the type of masonry, the wall’s ability to breathe, and the height of the water table.
When conducting an inspection, Chartered Surveyors have a duty to follow the trail and establish the likely cause of any dampness found within a property. However, due to pressures from mortgage lenders to use standardised paragraphs and the threat of potential litigation, many surveyors err on the side of caution. They often recommend further inspection by a “timber and damp-proof contractor.”
The Problem with Delegating to Contractors:
In my opinion, this practice represents a dereliction of a surveyor’s duty to impart professional expertise and impartiality to their clients. By passing the responsibility to a firm that, while well-meaning, may have a sales-oriented approach and a vested interest in specifying potentially expensive and disruptive works, the surveyor risks unnecessary damage to the property, particularly in the case of historical buildings.
The Importance of Accurate Diagnosis:
It is understandable that mortgage lenders and potential purchasers seek quick-fix solutions for damp problems. However, it is essential to recognise that many damp problems are caused by factors other than rising dampness. In most cases, these issues can be relatively simple to remedy. It is crucial to remember that a guarantee provided by a specialist damp-proofing company is only as good as the accuracy of the initial diagnosis. Misdiagnosing the damp problem from the outset renders any guarantee worthless.
Ensuring Dampness in Buildings is Appropriately Treated:
In conclusion, the misdiagnosis of dampness in buildings, especially the overuse of the term “rising damp,” raises significant concerns. Surveyors must fulfil their duty to impart professional expertise and impartiality, thoroughly investigating the cause of dampness and providing accurate assessments. A more nuanced approach to diagnosing damp problems, considering alternative causes and potential remedies before resorting to potentially expensive and disruptive measures, is essential. By doing so, we can ensure that buildings are appropriately treated, preserving their integrity and avoiding unnecessary expenses.
