BBC Watchdog catches damp proofing rogue trader

How to avoid rogue traders


Freephone :

Cathedral damp proofing, a nationwide damp proofing company, was exposed as a rogue trader in the latest episode of BBC Watchdog for recommending unnecessary damp proof injections without renewing damp plaster and not honouring their guarantees for the works.

Watchdog Rogue traders discovered that the company, formally ‘The Damp Detectors Ltd’, was fined 10 years ago for selling damp proofing treatments in areas where there was no damp issue.

BBC Watchdog Rouge Traders commented 

On their website, BBC Watchdog Rogue Traders commented: “We have heard from some of Cathedral Damp's more recent customers who are unhappy with their current service. They include Manjula, who asked the company to investigate a damp problem affecting the walls throughout the ground floor of her home in Preston. Manjula got a number of quotes but chose Cathedral Damp because they promised to fix her problem without removing the plaster. Less mess you see.”
