RICS damp expert Stephen Boniface defines the commonly accepted definition of rising damp before both he and fellow guest, Jeff Howell, claim ‘true’ rising damp doesn’t exist.
Construction lecturer turned author, Howell, cites his years of research and experimentation as evidence. He also questions the need for DPCs and claims chemically-injected ones are a ‘complete waste of time’.
The programme concludes that while rising damp is at best exceedingly rare, dampness in homes is a serious problem. The BRE methodology for testing for damp is illustrated, as is a discussion about the most likely causes of damp.
