Mould is more than just an unsightly stain; it is an unfortunately common growth that can harm your health if left untreated. These dangers come from its persistence despite regular cleaning attempts and how difficult it can be to prevent its return.

At ICE Cleaning, we are leading the way for mould remediation services across the UK. We work closely with local councils to adhere to Awaab's Law, ensuring that those living in mould-infested homes receive high-quality treatment options and know how to prevent its return.

Read on to learn more about mould and why you can prevent its return.

What is mould?

Mould is a common, yet misunderstood growth. It is a type of fungus that is always present in the environment. But, with excess moisture and organic matter to feed on, it starts growing rapidly.

Because of all of these factors and the consistent presence of mould spores, it is impossible to completely kill mould, but it is preventable. 

This fungus form, though tiny, can become a giant problem if not dealt with promptly. Its growth is triggered by high humidity, condensation, dampness or poor ventilation within your surroundings.

Mould can often grow on window sills where condensation creates perfect damp spots for mould colonies to thrive. Wooden frames provide plenty of organic material for moulds, while even uPVC may harbour dust or dead bugs that serve as a food source.

Even having houseplants basking on your windowsills can attract fungal growth. Their natural production of humidity helps create optimal conditions for mould growth.

The health implications of mould exposure

Mould can have severe health implications, particularly for those with existing respiratory conditions. The NHS outlines that exposure to mould spores may cause allergic reactions, asthma attacks, and even lung infections.

Allergic responses include sneezing, a runny nose or red eyes. However, anyone is at risk from certain types of toxic moulds such as Stachybotrys chartarum - also known as 'black mould'.

This type produces mycotoxins, which can lead to serious symptoms like chronic fatigue, persistent headaches and memory problems.

If you are noticing these health issues in your home or workplace, along with signs of dampness or mustiness, there is a chance you might be dealing with a mould problem.

 If left untreated, this could become more hazardous - especially for young children and the elderly who have weaker immune systems and are thus more prone.

Conditions that promote mould growth

Mould thrives in conditions we often unwittingly provide in areas like the kitchen and bathroom, where steam and heat occur during everyday activities. 

The life cycle of mould begins through airborne spores that can travel through open windows and doors, or cling to clothes and pets.

Once inside, they wait for ideal growing conditions: warmth (above 20°C), high humidity levels (over 60%), poor ventilation and organic material to feed on, such as wood or paper products.

Areas with chronic dampness attract mould because it provides the necessary hydration to grow. This includes spaces where water leakage might occur, such as roofs, walls near pipes, bathrooms and basements. If an area stays wet for over 24 hours, it is at an increased risk of mould growth.

Why mould keeps returning

Mould can keep returning despite your best efforts to eliminate it. This happens because mould spores are microscopic and always present, lingering as we breathe and on surfaces around us.

Although cleaning visible mould may seem enough, you have not eradicated all the hidden spores still lurking. According to the CDC, if you do not address underlying moisture issues that favour mould growth, such as leaky pipes or poor ventilation, then the mould will return.

To combat this recurring issue effectively requires comprehensive action, addressing existing infestations and potential hotspots for future growth.

An integrated approach combining deep-cleaning strategies with preventive measures is key, which can be achieved by a professional mould removal company.

Preventing mould infestations

Maintaining a dry and well-aired environment is essential to preventing mould growth. Dehumidifiers can help keep moisture levels low, especially in damp areas like basements or bathrooms. Even minor water damage can cause mould, so ensure you immediately tackle any leaks.

Cleaning regularly with mould-killing products on surfaces prone to dampness, such as shower tiles or window sills, helps too. However, this is not enough to destroy the spores, you will require professional cleaning for recurring growths.

Air purifiers are beneficial to those more susceptible to health problems from exposure, like asthmatics. HEPA-filtered air purifiers trap airborne particles, including tiny mould spores that would otherwise evade standard filters.

If all else fails, consider professional cleaning services, which have specialised equipment and expertise required for effective remediation of persistent infestations.

When to seek professional help for mould issues

If the mould is proving resistant to your attempts at removal, it is time to call in a professional. While strong cleaning products can remove smaller patches, expert attention is required for larger mould infestations.

One sign that you may need professional help is if the mould keeps returning despite your efforts at removal. This suggests there could be a deeper issue causing persistent dampness in your property - something that is difficult to fix without specialist knowledge.

Mould-related health issues are another red flag indicating the necessity of professionals. If residents or employees report symptoms such as coughing, sneezing, or skin irritation, professional intervention is needed.

Treating cases is not just about killing the visible mould, it involves preventing its return too. For this reason alone, engaging specialists with industry-grade equipment and techniques is crucial when confronting significant outbreaks.

Frequently asked questions

How can I identify mould in my home?

Mould is often visible as black, green, or white spots on surfaces and may also have a musty odour. It usually grows in bathrooms, kitchens, basements, and areas with water damage.

How can I prevent mould from coming back?

You should fix water leaks, ensure proper ventilation in humid areas, keep your home clean and dry, and use dehumidifiers. Regularly clean and maintain areas prone to mould, like bathrooms and kitchens.

Is it safe to clean mould myself, or should I hire professionals?

If the mould is extensive or if you have health concerns, it is best to consult with a professional mould remediation service. They have the equipment and expertise to deal with severe mould infestations safely.

Are there any types of mould that are more dangerous?

Some mould, like black mould, can produce mycotoxins that are harmful when inhaled. However, the health effects of mould can vary depending on individual sensitivities, so it is best to remove all mould promptly.
