Is Rising Damp a Myth? Unveiling the Truth with AMS Surveys

Is rising damp a myth? The answer requires a deeper look, as this issue often sparks debate among property owners and experts. At AMS Surveys, we aim to shed light on this common concern and help property owners avoid costly mistakes caused by misdiagnosis. Rising damp is often misunderstood, with many being misled. In fact, reading this blog could save you thousands of pounds. Let’s explore the truth behind rising damp and how we, as independent damp surveyors, provide accurate, cost-effective assessments.

What is Rising Damp?

Rising damp is the process where moisture moves upwards from the ground through porous building materials such as brick and mortar. This occurs due to capillary action, which is the ability of water to defy gravity and travel through tiny pores in the materials. It manifests as unsightly tide marks, peeling wallpaper, and damp patches on walls, which can damage the structure of the building over time.

The Myth vs Reality

The rising damp issue is often clouded by misconceptions. While some argue that modern construction techniques have rendered buildings immune to rising damp, this is not entirely true. Rising damp can affect both older and newer buildings, but it is essential to differentiate between rising damp and other types of moisture problems. Misdiagnosis often leads to expensive and ineffective treatments that may even worsen the issue.

For properties built after 1900, it’s important to note that they are often equipped with a physical damp proof course (DPC), which rarely fails. If rising damp is suspected, the problem is likely a breach or bridging of the DPC, which allows moisture to pass through the walls. Causes of such breaches can include blocked cavities or high ground levels.

Correct Diagnosis and Investigation of Rising Damp

Accurate diagnosis is critical when dealing with rising damp. At AMS Surveys, we use advanced diagnostic tools such as moisture meters, hygrometers, and chemical testing to distinguish rising damp from other damp issues. Calcium carbide testing, where permitted, is a reliable method for determining the true nature of the dampness in the walls. As independent surveyors, we provide unbiased damp and timber reports, ensuring you receive an accurate diagnosis without being sold unnecessary, costly treatments.

Unlike many companies that offer guarantees with damp proofing treatments, AMS Surveys does not push chemical injections as the default solution. In fact, we believe many misdiagnosed cases involve expensive chemical damp proofing treatments that provide little benefit. Trust our expertise to provide the most effective and cost-efficient solution for your property’s damp issues.

The Damp Proof Course (DPC) and Its Role

The Damp Proof Course (DPC) was introduced in the late 19th century to prevent moisture from rising through the walls of buildings. While DPCs are effective in most buildings, issues arise when they are breached or bridged. For properties built after 1875, a DPC is typically present and effective unless damaged by external factors such as high ground levels. However, many properties built before this time may not have had a DPC installed, leading to damp problems in the form of rising damp.

For older buildings, breathable materials like lime plaster were used to allow moisture to evaporate naturally from the walls, both internally and externally. These buildings were often better ventilated, which helped mitigate moisture issues. Adding non-breathable materials or attempting to install a DPC in these older properties can cause more harm than good.

AMS Surveys specialises in traditional, heritage, and listed buildings, providing expert advice on how to manage damp in these unique structures without resorting to expensive and unnecessary treatments.
