💦 DAMP SURVEY RESULTS 💦

BACKGROUND 👀
The owner of a Victorian ground-floor flat in South London noticed damp patches forming in the kitchen bay window, reaching up to one metre high. The issue began around 3–4 years ago, despite the client having lived in the property for nine years. A camera inspection confirmed the drain outside had been relined, and gutters above the bay window were replaced. However, there are concerns that a partially blocked airbrick—covered with concrete by previous owners—may be restricting airflow.

FINDINGS 🔍
✨ Damp at the base of kitchen bay window – possibly linked to poor ventilation
❌ Mould present in areas exposed to condensation
💨 Lack of a kitchen extractor fan allowing excess vapour to accumulate
✅ No evidence of rising damp despite prior chemical damp-proofing treatment
🛠️ Client is repainting exterior sills but penetrating damp remains a concern
💷 By resolving the root cause, estimated savings of £4,000
✨ Damp likely due to heat loss, condensation, and rainwater penetration

ACTIONS 🛠️
1️⃣ Reduce Cooking Vapour 🌬️ – https://damp.ai/target-vapour-from-co...
🍃 Cook with lids on pots and pans to cut vapour by up to 80%.

2️⃣ Run a Dehumidifier 🍃 – https://damp.ai/use-a-dehumidifier
Use a dehumidifier (e.g., PureMate, Duux Bora Smart, Meaco DD8L Zambezi) to maintain relative humidity. Set to 70% RH and drain into a sink when leaving the property vacant.

3️⃣ Improve Clothes Drying Methods 🌱 – https://damp.ai/improve-clothes-dryin...
Avoid drying clothes indoors unless using a ventilated tumble dryer or a dehumidifier. Do not dry clothes in the open without a dehumidifier.

4️⃣ Apply Dew’s Law 🔬 – https://damp.ai/dews-law
🍃 Keep internal vapour levels below external temperatures using ventilation and dehumidifiers. Monitor conditions with tools like the Habotest HT607 or ORIA Wireless Hygrometer.

5️⃣ Stop Penetrating Damp 🏡 – https://damp.ai/penetrating-damp
Seal sills around the bay window with impermeable mortar and check gutters during heavy rain to ensure they flow correctly.

6️⃣ Remove Surface Salts 🛠️ – https://damp.ai/remove-surface-salts
Gently sand away benign calcium sulphate salts. If the salts have disrupted the surface, use Easy Fill or another high-quality filler. Consider insulating the bay to reduce heat loss.

ADDITIONAL ACTIONS IF ALL ELSE FAILS 💡
1️⃣ Install a Kitchen Extractor Fan – https://damp.ai/target-vapour-from-co...
💨 A quiet, ducted extractor fan placed above or near the hob is essential for removing cooking vapour. Fans that operate quietly and automatically are used more frequently and improve kitchen ventilation. Avoid flexible ducting, which reduces efficiency.

2️⃣ Improve Airflow Through Airbrick 🌬️ – https://damp.ai/increase-airflow-thro...
Remove concrete obstructing the airbrick to restore airflow efficiency and prevent moisture build-up.

3️⃣ Insulate Cold Internal Surfaces 🏡 – https://damp.ai/add-targeted-insulation
Use Rockwool Thermal Lining Paper for minor areas or wood fibre insulation for larger sections to prevent condensation forming on cold walls.

VERIFICATION 📊
🕰️ Estimated Drying Time: 3–6 months, depending on ventilation, heating, and wall coatings.
📏 Monitor Progress:
✔️ Use a damp meter weekly, checking the highest damp point.

REASONING 🤔
💡 Mould forms when relative humidity exceeds 85% for prolonged periods.
💡 Blocked airbricks prevent effective airflow, trapping moisture indoors.
💡 Rising damp is virtually impossible in London, as groundwater is actively pumped out 30–60m below the surface.
💡 Fixing ventilation is more effective than chemical damp-proofing, which often exacerbates condensation.
