WARNING: Reading this blog and understanding Damp could save you thousands of pounds
Introduction
Is rising damp a myth? Is a matter of perspective and it requires some explanation, so please read on. The rising damp as with any type of damp scenario raises alarm and curiosity among property owners and experts about the nature and impact of rising damp. However, rising damp is the term that we see many clients ripped off, time and time again by so-called experts and builders who misdiagnose and carry out inappropriate building work. Reading this blog could save you thousands of pounds.
At AMS SURVEYS, we're at the forefront of demystifying this condition, offering clarity and solutions to concerned property stakeholders. Rising damp is a topic of much debate, but what does the evidence say? Let's explore the reality behind this phenomenon.
What is Rising Damp?
The theory behind Rising damp is essentially moisture movement from the ground up through porous building materials due to capillary action. It manifests as tide marks, peeling wallpaper, and damp patches on walls, which are not just unsightly but potentially harmful to the structure. The principle underlying this process is capillary action, where water defies gravity, moving through the tiny pores of materials like brick and mortar.

The Myth vs Reality
The concept of rising damp is often surrounded by myths and misconceptions. Some argue it's a problem confined to the past, while others believe that modern construction techniques have rendered buildings immune to it.
However, rising damp is a real concern, affecting both old and newer buildings. It's crucial to differentiate between genuine rising damp and other forms of moisture, as misdiagnosis can lead to ineffective treatments, wasted resources, additional cost and in some cases make the problem worse.
The 'rising damp' is a symptom and not the cause of the dampness. Black Spot Mould is a symptom of condensation as a result of high moisture in the air creating high humidity, likely caused by poor heating and ventilation. Similarly, we can apply the same to rising damp, for example, if your property is built somewhere after 1900 it is likely and even more likely the younger it is, to have a physical damp proof course (DPC) and these very rarely become defective. Therefore the cause is likely to be a breach or bridging of the DPC allowing moisture to pass or penetrate the walls, this could be blocked cavities, high ground level etc.
So what about an older solid wall or a property without a DPC? Read this here.
Correct Diagnosis and investigation of Rising Damp
The accurate identification of rising damp is a complex process that requires the expertise of Building Surveyors, such as those at AMS SURVEYS.
Utilising advanced diagnostic tools like moisture meters, hygrometers, and chemical testing, our team can distinguish rising damp from other damp issues, ensuring that remedial building work is appropriate.
If you suspect rising damp, whoever you instruct to investigate the cause of dampness should carry out a calcium carbide testing, where permission is granted.

As we are independent, our damp and timber surveys have an unbiased view of the work specified. Many companies offer damp surveys and will specify a fix with a guarantee but you need to pay them to fix it, usually, thousands and the guarantees are as strong as dry spaghetti. In most cases, great marketing and sales usually result in the wrong diagnosis/solution and a costly mistake. Trust us you don't need to spend £5,000+ on a chemical injected damp proof course. You likely need to carry out much cheaper repairs. The only reliable way to test the dampness of a wall is Calcium Carbide Testing
The introduction of the Damp Proof Course (DPC)
DPCs became compulsory in London circa 1875. Typically a layer of slate was also employed as a DPC, which later became bitumen and then the modern version which is plastic. However, there is a variance in when properties exactly had DPCs installed between 1875 and around 1920-1945, due to building standards and the obvious two world wars. Around the same time, Cavity Wall construction became more prevalent, as such penetrating damp became less of an issue too. Anything built after this period will generally have a DPC and I'm still to come across a property with a DPC that has rising damp caused by a failed DPC, what I have found is thousands of misdiagnosed retrospectively installed chemical chemical-injected DPCs. Which usually results in damp after time rearing its ugly head once more. There are many building defects that can cause dampness which manifests as rising damp, such as high ground levels under floors or external areas. That is where you need an Expert Building Surveyor to thoroughly investigate and specify the correct remedy.
What about buildings before DPCs?
Damp in Solid Walls
The simple answer is they got damp. However, using breathable materials such as lime plaster, allowed the building to evaporate moisture from the walls externally in the fresh air, wind and sunshine, internally through ventilation of draughty windows and doors, the use of fireplaces and a difference in the style of living. This allowed the walls to quickly evaporate and remove the moisture from the walls into heated and ventilated spaces. Often walls were also hidden behind timber paneling now back in vogue!!
A really good saying to remember before opting for an expensive chemical injection or new DPC, if it wasn't built with one it doesn't need one. In most instances trying to add a non-breathable material to an old building in particular will have significant issues causing more damage in the long term.

So in most properties, unless it's very old, it's likely you got a perfectly good DPC. So unlike most don't jump to the conclusion of rising damp. However, treating 'rising damp' symptoms varies from property to property, repairing drainage, removing inappropriate renders and plaster to improving ventilation. Damp is a condition that demands a customised approach, considering the specific needs and characteristics of each property and the cause. AMS SURVEYS specialises in crafting and implementing strategies that not only address the symptoms but also protect against future moisture intrusion, as supported by practical experience, scientific and intrusive investigation and expert professional knowledge.
Misdiagnosis and Incorrect Repair of Damp
Here is a great example of a company installing a chemical inject damp proof course. The 'special chemicals' are being installed too high (compared to the location of a physical DPC in line with Building Regulations) in the wall and dampness will allow the timber floor to decay and rot, if that wall is actually damp even in the photo the wall looks fairly dry. This process is usually carried out on both sides of the wall. This tells me either the installer doesn't know where a DPC should be installed or it can't be installed low enough in the correct place because the ground level is too high.

FAQs about Rising Damp:
1. Is rising damp always the cause of moisture in older buildings?
No, rising damp is not always the culprit. Moisture in older buildings can result from various issues, including poor ventilation, condensation, leaking gutters, or high ground levels. Accurate diagnosis is crucial to determine the exact cause, and professionals like AMS SURVEYS can provide a thorough assessment to identify the true source of moisture.
2. Can rising damp be misdiagnosed?
Yes, rising damp is frequently misdiagnosed, leading to costly and ineffective treatments. Misdiagnosis often occurs when the actual cause of damp is not correctly identified. At AMS SURVEYS, we use advanced diagnostic tools and expert analysis to differentiate between rising damp and other forms of moisture intrusion, ensuring you get the correct solution.
3. What are some common misconceptions about rising damp?
A common misconception is that rising damp only affects older buildings or that it's an outdated problem. In reality, rising damp can occur in both older and newer buildings if certain conditions are present, such as a breached or absent damp-proof course (DPC) or high external ground levels. Another misconception is that chemical injections are always necessary, which is often not the case and can lead to wasted expenses.
4. How can I tell if my property has rising damp?
Typical signs of rising damp include tide marks on walls, peeling wallpaper, damp patches, and a musty smell. However, these symptoms can also be indicative of other damp issues. If you suspect rising damp, it’s essential to have a professional inspection conducted by an independent surveyor like AMS SURVEYS, who can accurately diagnose the issue using tools like calcium carbide testing.
5. What should I do if I suspect rising damp in my property?
If you suspect rising damp, contact a qualified and independent surveying company such as AMS SURVEYS for a comprehensive inspection. We’ll assess your property using expert techniques and tools to provide a correct diagnosis and recommend effective, tailored solutions that address the root cause of the problem.
6. What is the importance of a Damp Proof Course (DPC)?
A Damp Proof Course (DPC) is a critical element in buildings designed to prevent moisture from rising through walls. Buildings constructed after 1875 in the UK typically include a DPC, and it’s usually very effective unless breached or bridged. AMS SURVEYS can assess the condition of your DPC and determine whether it’s functioning correctly or if other factors are contributing to moisture issues.
7. What are the risks of improper treatment for rising damp?
Improper treatment, such as unnecessary chemical injections or failure to address the actual cause of damp, can lead to further structural damage, ongoing damp issues, and wasted money. AMS SURVEYS provides independent, unbiased advice to ensure that you receive the correct treatment for your property’s specific needs.
8. How does AMS SURVEYS approach the treatment of rising damp?
At AMS SURVEYS, we take a holistic approach to damp treatment. After accurately diagnosing the issue, we tailor our solutions to address the underlying cause of the damp, which may include repairing drainage, improving ventilation, or addressing breaches in the DPC. Our goal is to ensure long-term protection for your property, not just a temporary fix.
9. Can rising damp reoccur after treatment?
Rising damp can reoccur if the treatment doesn’t address the root cause. This is why accurate diagnosis and appropriate treatment are critical. AMS SURVEYS ensures that all factors contributing to damp are identified and treated effectively to prevent future problems.
10. Why should I choose AMS SURVEYS for my damp-related concerns?
AMS SURVEYS offers expert, independent assessments backed by years of experience and advanced diagnostic tools. Unlike companies that may push unnecessary treatments, we provide unbiased advice focused on delivering the correct solution for your property. Our commitment is to safeguard your home’s structural integrity and value by addressing damp issues the right way.
11. Do I need a new Damp Proof Course (DPC)?
In many cases, the original DPC is still functioning effectively. Rising damp symptoms are often due to other issues, such as a bridged or breached DPC, or external factors like high ground levels. Before opting for an expensive chemical injection or new DPC, if it wasn't built with one it doesn't need one, it’s crucial to get an accurate diagnosis from an independent surveyor like AMS SURVEYS. We ensure that the actual cause of damp is identified and that the correct, cost-effective solution is recommended.
12. Should I tank my walls to stop damp?
Tanking, or applying a waterproof coating to walls, might seem like a quick fix for damp issues, but it’s not always the right solution. Tanking can trap moisture within the walls, potentially causing more significant problems over time. The key is to address the source of the damp, not just the symptoms. AMS SURVEYS provides expert advice to determine whether tanking is appropriate for your situation or if other, more effective methods should be considered.
