We are experts in mould treatment and prevention.  Mould is now a common problem within our homes. With improved building features such as cavity wall insulation, double glazing and air tightness, ‘natural ventilation’ is prohibited. Stale air is trapped leading to musty smells, dampness and mould growth.
Older properties tend to suffer more than new ones due to poor insulation and cold surfaces.

The problem varies from a small patch of mould or discoloured wallpaper behind the wardrobe, in the very top corner of a bedroom, to serious amounts of mould growth across walls, ceilings, inside wardrobes and on clothes, furnishings, carpets and in basements.

It’s a serious problem because of the health risks associated with mould spores. The mould fungi have been identified as the source of many health problems, including infections, asthma, allergies and sinusitis.

Moulds produce allergens, irritants, and in some cases, toxins that may cause reactions in humans.

Why are some properties particularly prone to the problem?

Moulds typically grow in buildings affected by high levels of humidity. This humidity may be caused by an ongoing damp issue or maybe down to the lack of ventilation in the property.

The main causes of mould:
• Wet or damp walls.
• Condensation from high relative humidity in air
• Too much water vapour or steam being generated in the property.
• Poor ventilation
• Inadequate heating
Inadequate extractors fitted in bathrooms and en suites.

Mould growth and Condensation

Mould growth is often complex and a combination of things. It is sometimes caused by inadequacies in the building but very often the main cause of mould growth is the lifestyle of the occupants.

Once the mould growth has been allowed to germinate and develope, it can reoccur again and again.

Houses have become effectively sealed boxes, keeping in any moisture produced within the house and providing ideal conditions for condensation to occur.

Ventilation is only effective if it is consistent throughout the whole envelope of the property. Condensation is encouraged by poor air circulation where stagnant air pockets form (behind furniture and in cupboards) and the first evidence is often the appearance of mould growth and a musty smell on clothes in wardrobes.

The warm moist air rises to the highest points in the property, forming condensation in those areas, which are often coldest, including bedrooms, wardrobes, bathrooms and toilets etc.

The modern life style, means that many houses remain unoccupied and unheated throughout the greater part of the day, allowing the fabric of the building to cool right down. The moisture producing activities are then concentrated into a relatively short time period, producing large amounts of steam when the building structure is still relatively cold.

Installation of a Positive input Ventilation System (PIVS) in the property.


The PIVS draws fresh air into the dwelling from outside and filters it before being delivered into the property.
Moisture laden air is diluted and replaced with clean, filtered air resulting in

  • Improved ventilation within the property.
  • Improved heat distribution.
  • Reduce Relative Humidity.
  • Lower Dew point

This eliminates or reduces surface condensation, which causes mould growth, providing a significant improvement in the health of asthma sufferers and general indoor air quality.
