Damp in a house happens when unwanted moisture builds up in walls, floors, or ceilings.
The main causes include:
1. Rising damp – This occurs when moisture from the ground moves up through walls by capillary action.
2. Penetrating damp – This is caused by water entering the building from outside. It can happen due to leaking roofs, damaged gutters, cracked walls, or faulty window seals.
3. Condensation – This is the most common cause of damp. It occurs when warm, moist air inside the house touches cold surfaces like windows or walls, forming water droplets. Poor ventilation, cooking, drying clothes indoors, and hot showers can increase condensation.
4. Leaks and plumbing problems – Broken pipes, leaking radiators, or faulty plumbing can allow water to escape and soak into walls and floors.
If damp is not treated, it can lead to mould growth, damage to the building structure, and health problems. Improving ventilation, fixing leaks, and repairing structural issues can help prevent damp.
