Damp can cause mould and lead to serious damage to your home’s building materials.
Installing damp proofing is one of the best ways of preventing damp problems in your home.
When checking for accreditation, don’t just take the company’s word for it or be impressed with the logos they boast on their site, but find out for yourself what kind of accreditation they possess. The damp proofing industry in the UK is represented by the Property Care Association (PCA). They conduct regular audits with accredited companies to make sure that strict standards regarding workmanship and the employment of qualified surveyors are met.
To verify whether a contractor is accredited by the PCA you can check their website at http://www.property-care.org/.
You may also want to check whether the surveyor that the company you hired sends you is adequately qualified. The surveyor should possess the professional qualification developed by the PCA for damp and timber diagnosis surveyors: the Certificated Surveyor in Remedial Treatment (CSRT) qualification.
