What kind of damp is affecting your home?
There are three types of damp which may be damaging your home. Each type of damp has a separate cause and treatment. If your home is suffering from damp, and you are unsure as to which type you are dealing with, read our damp guide below to find out all you need to know about these three most common damp conditions.
Condensation is most likely to affect every home, usually during the winter. Condensation is caused by an excessive amount of moist air circulating in the home which cannot escape. Condensation forms when warm moist air comes into contact with a cold surface. As the air is cooled by the cold surface, moisture is deposited on the cold surface in the form of water droplets.
This issue is exacerbated by poor ventilation which usually occurs in winter as homeowners are more hesitant to leave windows open due to the cold.
Your home is suffering from condensation if you can identify any of the following symptoms:
• Black mould on walls, ceilings, furnishings (bathrooms and kitchens usually suffer from this)
• Musty odour
• Water droplets form on cold, impervious surfaces such as glass and paint
• Damp wallpaper
The primary action you must take to cure condensation is to improve the home’s ventilation.
Home ventilation systems are designed to provide a continuous air change, replacing stale and humid air with fresh and clean air. This continuous air exchange will ensure that condensation and mould growth problems will not grow and thrive. Home ventilation systems also fight against health risks associated with condensation. Fresh, filtered air will reduce the risk of allergies and asthma which are the most common risks caused by condensation problems.
Heating will also need to be adjusted. Heating should be set or applied to give a low-level background heat to ensure that there are no rapid changes to the temperature. This will keep wall surfaces warmer over a period of time reducing the risk of condensation.
Rising damp is caused by water seeping into the walls from ground level. Water seeps through tiny holes in the building’s bricks similar to how a sponge absorbs water.
Your home is suffering from rising damp if you can identify any of the following symptoms:
• A tide mark on the wall’s decoration
• Damage to skirting boards
• Crumbling plaster
• Peeling paint or wallpaper

Rising damp can be cured and prevented by installing a damp proof membrane. They can be applied with little surface preparation, both internally and externally. A damp proof membrane works immediately once installed. Key benefits include:
• Isolation of damp walls
• Cures deteriorated surfaces
• Protects walls against salt contaminants
Penetrating damp occurs when water leaks through the walls due to a variety of building defects. These can include faulty joints, damaged guttering and faulty roof coverings. The problem is often exacerbated after rainfall. Click through for more on protecting brickwork to avoid penetrating damp.
Your home is suffering from penetrating damp if you can identify any of the following symptoms:
• Look for block drainpipes or leaking gutters
• Damp patches on walls, ceilings and floors
There are several water repellents suitable for curing penetrating damp. View our range of water repellents.
