Why do so many so called specialists damage properties with totally wrong damp remedies

ask the property care associating whos members are the main people carrying out this type of work , or the insurance / mortgage company's requesting this type of work completed with its 30yr insurance guarantee thats not worth the paper its written on, dampness issues are misdiagnosed in over 75% of cases rising to 95% in older property's have even come across insurance company experts who spent yrs at uni learning how to wreck older property s unfortunately we live in a society that wants instant solutions s to there problems & therefore allows these cover up company s to thrive

A large percentage of housing stock in Britain is 80 years or older and of brick construction. The understanding of building principles and the use of materials for these structures from that era (and older) is not taught in depth in the currently very basic training courses available for trademen and women. To remedy this problem, ALL building trades should be regulated and include higher training standards and longer training times and should result with a qualification that is meaningful not dissimilar to the guild system in continental Europe (5 year minimum apprenticeship with the option to add more training time and examinations to obtain "Meisterbrief"), see link: https://en.wikipedia.org/wiki/Master_craftsman. These are independent national training schemes not linked to individual companies or producers/ designers of building products and systems. Read between the lines... These systems used to be in place in the UK up until the 1950s, after that the building education system was deregulated (combined with a lack of workers) to enable the building of postwar housing, very quickly. Today, many of these badly designed and constructed buildings have either been demolished or are not fit to be lived in. In short: Good quality education could lead to better building and restoration practices and a more appreciative view of builders in society.

Totally agree

there are only 3 forms of damp in any given property. rising damp penetrating damp condensation. Now that's the easy part, the hard part is determining which one of these is causing the problem. A decent builder will have the knowledge to rectify the problem. Most but not all damp issues at ground level are due to rising damp..ie damp course failure or non existent damp course, also damp course bridging. Another problem is salts in masonry. The first floor level damp issues are more than likely caused by penetrating damp or condensation. ie faulty guttering, external pointing or rendering, and bathroom ventilation issues. There are always the exception ie flooding and leaking pipes.

Seems to me like they don’t know what there doing. In my experience it’s rising damp from the ground! There was no membrane or damp corse in those days Especially in farm buildings. Rising damp will climb 1 meter from external ground level. Render will carry water up the wall if it’s close to the ground. Check gutters and damage to render if renderd . Also exterior walls joining the building.
