What is Mould and Black Mould?

Mould, including black mould, often occurs as a result of condensation where humidity in the air condenses on surfaces which are low enough in temperature.

Certain types of black mould can be more severe as they are toxigens, meaning they produce toxins. Not only does mould have a very unsightly appearance, it can be a nasty problem to deal with in your home, especially as black mould comes with negative connotations.

Choose Prokil today and our expert-trained mould specialists can get to work straight away by determining what is causing black mould in your home. We will then implement an effective mould treatment plan to ensure that the related underlying damp issues are solved within your property.

How Does Mold Occur?

You might be wondering, what causes mould and black mould? Mould, including black mould, often occurs when airborne moisture comes into contact with a surface cold enough for it to turn into small water droplets. This then creates the perfect environment for mould spores which are present in the air to settle and to germinate. As the mould grows and can spread to other surfaces including woodwork, plaster, furniture and other personal items.

The problem is often brought about through activities such as cooking and showering without sufficient means of ventilation, as they both produce large quantities of water vapour.

What Are The Effects of Mould?

Mould, in particularly black mould, could have negative impacts on your health. Generally, inhaling or ingesting black mould is associated with poor health in both humans and animals. This mainly affects major groups such as the very young, the elderly and people with respiratory conditions such as asthma. Therefore, black mould treatment is very important when you first notice it.

Should you be concerned about your health then Prokil always recommends you seek medical advice.

How To Identify Mould

Luckily, due to its displeasing appearance, mould is fairly easy to spot.

Black mould has quite a distinctive appearance. During the active and germinating phase, black mould is often very dark green or black, and can even be slimy.

During the inactive phase, it will have a dry and powdery appearance. But, don’t forget that black mould can be problematic during either phase, therefore we do not recommend putting off mould treatment for an extended period.

Some of the generic mould symptoms to look out for are:

  • Black spots clustered together
  • Green patches on walls
  • Wet patches on ceilings, walls or floors
  • A musty smell in rooms or cupboards
  • Water droplets on the inside of windows
  • Plaster that becomes bubbled

Mould & Black Mould Treatment

We recommend a very thorough mold and black mold treatment and removal to ensure that your home is mold-free.

We advise on how to ensure that your property is ventilated and heated correctly, which includes having appropriate extractor fans fitted and windows with openings. We offer two types of ventilation systems to help prevent mold from returning, which include:

  • Passive Air Vents (PAVs)

Our mold specialists recommend PAVs, which work by allowing excess moisture to dissipate through them whilst the specialist filter prevents cold air from entering your property. No electricity is required, and these operate 24 hours a day.

  • Positive Pressure Ventilation System (PPVS)

This is our second system designed to prevent mold growth. A PPVS ensures the air in the home is both filtered and heated. This works by helping to decrease stale air and humidity levels by increasing the pressure within the property.
