External Wall Leakage Survey Cases

External wall leakage is one of the most common yet challenging problems in Hong Kong buildings — the source is often hidden, neighbouring units are affected, and responsibility for repairs is difficult to determine. SILVER SURVEYORS’ external wall leakage cases document how we deploy non‑destructive testing techniques such as infrared thermography, smoke testing, high‑pressure water injection, and dye tracing to penetrate through tiles and plaster, pinpointing the exact origin of the leak. From luxury high‑rise apartments to old tenement buildings, from window seepage to roof cracks, each case presents a complete investigation logic, a legally compliant pathway, and the critical details that ultimately helped clients successfully resolve leakage notices or complete insurance claims.
