Senior Senior Members of the Dampproofing and Waterproofing Association of South Africa are required to abide by a code of conduct.
Be extremely wary of long guarantees offered to you (5 – 10 years or more) as the products used are seldom guaranteed by the manufacturer for such periods of time. The guarantee may also contain fine print compelling you to pay a percentage of the initial quotation every two years! Be extremely wary when repairs are undertaken by individuals driving an unmarked vehicle.

Remember, damp in a wall may have many causes and it may take an expert to identify the root of the problem.
Also remember that just because someone offers you a free survey it does NOT mean that they are qualified or even capable of doing one.
Check to see how long the company has been in business, dodgy dampproofers often over-claim this one!
