Mould Remediation Work In Commercial And Private Properties

Mould removal can be done quickly only for the mould to return. Why is this black mould so difficult to get rid of. Black mould is a result of damp and mould are excess moisture. Moisture in buildings can be caused by leaking pipes, damage to the roof, windows that are rotten. In many newly built home damp can occur if the water used when the house was built is still drying out. Black mould, also known as ‘Stachybotrys chartarum’ – latin name is a living organism.

Mould is a serious risk to your health. Asbestos and Mould Have Been Classified as Category 1 Risk According to (HHSRS).

After flooding then mould is your next worst level of risk. A damp property represents the ideal growing conditions for mould to grow. It is not the actual presence of the mould that is the greatest threat but the presence of spores.

Mould infestation can be categorized into one of four categories. These category levels are important in determining when this could be treated by yourselves and when you should call in the experts.

Mould Infestation Categories

  1. Level 1 – Infestation less than 1 square metre. Can be dealt with by anybody. However what lays on the surface is usually only a small amount of what lays underneath.
  2. Level 2 – Infestation between 1 and 10 square metres. Can be really hard to deal with and can escalate very quickly to Level 3.
  3. Level 3 – Infestation greater than 10 square metres should be dealt with by one of our technicians. We are fully qualified in large scale mould removal. We have been doing this for over 19 Years.
  4. Level 4 – Internal HVAC (Heating, Ventilation Air Conditioning) used in most office blocks, businesses and some homes. The spread of mould spores within HVAC environments can result in employees becoming seriously ill.  At Level 4 only experienced technicians should deal with these levels of infestation.

Black mould exists in many homes and offices without you even being aware of it, such as under floor boards and in wall voids.  Visible black mould can exist on walls, window sills and ceilings.  Signs of black mould can include a musty type smell which can be prevalent in damp conditions.

Wet mould will typically have a fungal and glossy black appearance. When it dries black mould will have a powdery consistency, and is it this that can cause major issues. The spores can then easily float almost invisibly to other parts of the building and into people’s lungs.

It made us laugh. It was fortunate that no one was in the house at the time because if it can come through toughened glass on a patio door, and through furniture, then it wouldn’t have stopped for a mere person….”Paula Smith
