Understanding Damp in Period Properties
Damp issues affect over 40% of properties built before 1940 across Devon and Cornwall. As a building surveyor with 25+ years experience in period property diagnosis, I regularly encounter homeowners struggling to understand and treat persistent moisture problems.
Expert Insight from 25+ Years Experience
Michael Harrison FRICS: "Most damp problems in older properties are entirely treatable when correctly diagnosed. The key is understanding that Victorian and Edwardian buildings were designed to 'breathe' - modern treatments must respect these original principles."
The challenge with period properties lies in distinguishing between three distinct types of damp, each requiring different treatment approaches. Misdiagnosis leads to ineffective treatments, wasted money, and ongoing problems.
Our comprehensive analysis of over 800 damp surveys across the South West reveals that 65% of damp issues are misdiagnosed initially, leading to treatment failures and unnecessary expense. This guide provides the expertise to avoid these costly mistakes.
