Pete recently did an interview on BBC Radio 4 - You and Yours - which investigated a case history of failed cavity wall insulation.
One of the most frequent companies we come across who issue fraudulent 'survey reports' is Timberwise. We have a large collection of Timberwise reports - all of which are the same, and frequently for figures in excess of £5,000. In every one, the damp course is apparently 'breached' and injection damp proofing and tanking is required.
Whenever we are called to look at one of these cases, we find that damp proofing is not required, and in fact simple solutions are always possible - fixing of leaky gutters, leaky drains, or sometimes just opening up sub-floor air vents. In not ONE of the many dozens of cases of Timberwise damp reports we have investigated was there a need for any damp proofing. Every one of their 'surveys' was in fact a case of fraudulent mis-selling of a service that was not needed and would not have done anything for the building. In fact the buildings would have been irreparably damaged by the damp proofing.
Timberwise were taken to court for illegally dumping asbestos:
Would YOU want these people to do a survey for you, when you knew all the surveys were the same - fraudulent attempts to sell damp proofing on the back of mis diagnosed and mostly non-existent problems?
In every case the 'survey' used a damp meter. Three British Standards say that damp meters cannot be used for measuring moisture in building materials - BS 7913: 2013, BS 6576, and BS 5250. Why do Timberwise continue to use damp meters in the face of these standards? Simple - because the British public don't know, and Timberwise play on the innocence of their victims - waving a damp meter around saying 'You've got rising damp' - when in every case, no such thing exists.
