💦 DAMP SURVEY RESULTS 💦
BACKGROUND 👀
This property has recurring dampness in the bedroom. A plume of mould was identified near the bed head, and the damp staining suggested water ingress from rain. A detailed inspection revealed that the primary source was cracked render, particularly on the neighbour's side.
FINDINGS 🕵️♂️
🌟 Finding 1: Brown stains on the internal wall — a classic sign of penetrating damp. 🟤🏠
❌ Finding 2: Cracks in the external render, allowing rainwater to seep in. 🌧️🕳️
💨 Finding 3: High internal humidity levels contributing to mould growth. 🌫️🦠
✅ Finding 4: No evidence of rising damp — groundwater risk is minimal in this area. 🚫💦
🔍 Additional Findings: The neighbouring property's render damage exacerbated the issue.

Drying Time: Estimated 2–4 weeks depending on weather and ventilation.
Monitor Progress:
Use a damp meter weekly.
Compare sub-floor humidity with external readings using data loggers.
REASONING 🧐
Rising damp is unlikely in urban areas like London, where groundwater is 30–60m below the surface.
Penetrating damp from render cracks allows rainwater to seep through the walls.
Fixing these cracks is less risky and more effective than chemical damp treatments, which only mask the problem.
