Common Causes of Damp
There are three main types of damp found in residential properties:
Rising Damp Rising damp occurs when moisture from the ground travels up through walls due to a failed or missing damp-proof course. This often results in tide marks on walls, peeling paint, and crumbling plaster.
Penetrating Damp Penetrating damp is caused by water entering the building through external defects such as damaged brickwork, leaking gutters, broken roof tiles, or poorly sealed windows. It usually appears as damp patches on walls or ceilings and can worsen after heavy rainfall.
Condensation Condensation is the most common cause of damp in modern homes. It happens when warm, moist air comes into contact with cold surfaces, leading to water droplets forming on walls, windows, and ceilings. Poor ventilation, drying clothes indoors, and inadequate heating can all contribute to this problem.
The Dangers of Black Mould
One of the most serious consequences of damp is the growth of black mould. Black mould thrives in damp, poorly ventilated environments and releases spores into the air.
Prolonged exposure can cause respiratory problems, allergic reactions, skin irritation, and can be particularly harmful to children, the elderly, and those with asthma or weakened immune systems.
Black mould also damages walls, ceilings, and furnishings, making the problem increasingly costly if ignored.
The Importance of Professional Damp Surveys
Accurately identifying the cause of damp is essential, as each type requires a different treatment. Damp surveys should always be carried out by skilled and experienced damp surveyors. Professional surveyors use specialist equipment and in-depth knowledge to diagnose the source of moisture correctly, preventing unnecessary work and expense.
A thorough damp survey ensures the right solution is applied, protecting your home, improving indoor air quality, and safeguarding your health.
