Local Insight
True rising damp is less common than many damp-proofing companies claim — condensation and penetrating damp are far more prevalent in London. Be wary of free surveys from companies that always diagnose rising damp (and sell expensive DPC injection). An independent damp survey (£150–£350) gives you an unbiased diagnosis. Many London damp problems are caused by blocked gutters, failed pointing, or poor ventilation — all cheaper to fix than a new DPC.
