There is a considerable amount of confusion online about the topic of rising damp. Some say it does exists, others say it's very rare, while some others categorically deny its existence.

If you have been doing research on how to tackle dampness in old buildings, you probably run into Peter Ward from Heritage House dot org, ending up upsetin disbelief or alarmed by some of his statements and conclusions.

Is everyone out there evil, corrupt and after your money, as part of a big scam - except one man, Peter Ward, who is on a mission to expose it all in order to protect old building owners? Not quite.

Heritage House - A web of lies

The information contained there is the personal opinion of ONE man only who depicts a very sinister story of the UK building and conservation industry.

His whole ideology and website is built upon two fundamental statements - both of them lies. These two statements are: (click on the arrows / toggles for more info)

1. Rising damp, as a phenomenon, doesn't exist.

2. Rising damp has been invented in 1962 by the damp proofing industry with the sole purpose to scam and defraud the general public.

Let's look at both of these statements in a bit more detail and see whether independent, third party data supports or refute these claims.

Statement #1: Rising Damp Doesn't Exist

After an extensive research of the scientific literature, here are some of the many research papers from all over the world, all of them confirming the existence of rising damp, while also highlighting some of the damages it can create in old buildings.

Statement #2: Rising Damp has been invented by the damp proofing industry with the sole purpose to defraud the general public

Spending a few hours digging through Google's old books digitization project, I found some relevant historical references dating between 1840 to 1910 which consistently mention rising damp, damp proof courses and various period damp treatment methods.

A Treatise on Hygiene and Public Health - 1892

The study of the scientific and historical literature leads us to the following conclusions:

  • Rising damp, as a natural phenomenon, does exist and it's a real problem in old buildings. This has been known and consistently documented since Georgian times. Today's scientific research papers also confirm its existence.

  • Researchers agree upon that rising damp is a complex phenomenon, which despite all modern technical advances, we don't yet fully understand. The research, however, is ongoing.

  • Rising damp can and has been successfully reproduced under laboratory conditions many times - some research papers listed above evidence that fact.

  • Around the 1870s the connection between damp houses and health problems became very clear, As a result a number of health acts have been passed on throughout Britain, among other things addressing the problem of damp dwellings and of rising damp.

  • The need for damp proofing developed as a natural consequence to resolve the problem of damp dwellings - in order to make houses drier, healthier and warmer. The damp proofing industry handles a very real problem - not an imaginary or an invented one.

Today's Damp Proofing Industry

Peter Ward suggests that today's damp proofing industry has no legitimacy, and it has been "invented" with the sole motivation to scam and defraud old building owners. All historical documents confirm that this is not the case.

The fact is that today's damp proofing industry as a whole is not better nor worse than any other industry. It is very similar to any other trades or industries, having both high-quality professionals and "cowboys" alike.

I would use the car industry as a comparison as virtually everyone today drives a car, and thus has first hand experience with car dealerships or car repair shops. Among reputable car repair shops aren't out there "cowboy" repair shops that do a sloppy job, overcharge clients or take advantage of the vulnerable or less knowledgeable? Of course they are. Do these examples make the WHOLE car industry a scam that must be eradicated without any judgement? Of course not.

The Role of Peter Ward - His Real Character

For the past decade Peter Ward has been extremely busy creating and maintaining an ongoing conflict between the following three parties:
  1. The conservation industry
  2. The damp proofing industry, and
  3. Old building owners

Presenting himself as a "conservationist", he has been primarily targeting old building owners (the least knowledgeable group on technical matters, thus the easiest to manipulate), being extremely busy in alienating them from the damp proofing industry. His "black marketing" behind the scenes also resulted in considerable distrust between the fields of building conservation and damp proofing.

He achieved all this by two deceptive statements, presented as self-proclaimed "truths". 

The first statement (that rising damp doesn't exist) is not only a technical falsehood, but he used this as a pretext to go after and destroy the professional reputation of anyone who questions the validity of this statementAny professional voicing publicly that rising damp does exist became his target, as it posed a threat to his shady character. So he took "justice" into his own hands and became busy inventing "facts" or publishing "revealing articles", going to great lengths (in many cases bordering illegal) in his quest of destruction.

His second statement (the "conspiracy theory" of the damp proofing industry, that everything is a large-scale scam) created a lucrative foundation for his deceptive marketing strategy, selling overpriced surveys (£1,000 - 1,500) and telephone consultations (£200). After all, convincing old building owners that everyone out there is a scam and after their money, and they shouldn't trust anyone - except him - is one way (although shady and very reprehensible) to get some attention and make some easy money for a good living, "fishing" in the murky waters of self-generated confusion.

His destructive behavior was not limited to damp proofing companies or technologies, but he published libelous statements about leading heritage organizations, professional groups or individuals, even his own customers. 

Here are some real-world examples of Peter Ward "in action". You are welcome to draw your own conclusions.
