Condensation, damp and mould

Condensation, damp and mould can affect any home and may cause serious health problems if not dealt with quickly. Hinckley & Bosworth Borough Council is committed to providing safe, dry and energy‑efficient homes and to responding promptly when damp or mould is reported.

Why damp and mould matter

Living with damp or mould can:

• Worsen asthma and breathing problems
• Increase the risk of respiratory illness
• Affect mental wellbeing
• Cause damage to your home and belongings

Children, older people and those with health conditions can be more vulnerable. We take a person‑centred and health‑led approach to every report.

What is condensation?

Condensation happens when warm, moist air meets a cold surface, such as:

• Windows
• External walls
• Corners of rooms

Moisture in the air is mainly caused by everyday activities such as:

• Cooking and boiling kettles
• Bathing and showering
• Drying clothes indoors
• Breathing, especially when sleeping

If this moisture cannot escape through ventilation, it settles on cold surfaces and can lead to dampness and mould growth.

Is it condensation or another type of damp? 

Condensation is common, but it is not the only cause of damp and mould. 

Penetrating damp

Caused by water getting into the property from outside, for example:

• Leaking roofs
• Damaged gutters or downpipes
• Cracked brickwork
• Faulty windows or doors

Rising damp

Moisture rising from the ground due to problems with the damp‑proof course. This often leaves visible marks on windows and walls.

Leaks

From internal pipework, appliances, showers or heating systems.

If you are unsure what type of damp you have, please report it. We will inspect the problem and identify the cause.
