There are hundreds of home remedies for removing mould, from spraying the area with baking soda and water, to wiping it down with vinegar. While they might remove the dark, sooty spots, it will not be long before the mould returns.

Here at ICE Cleaning, we can get rid of mould and provide guidance on how to prevent it in the future. Our mould remediation services also come with a lifetime guarantee* so you can be sure it is gone for good.

In this blog, we go through why mould comes back after treatment and how to stop this.

What causes mould?

Mould grows on organic material, like paper or wood, in humid conditions. It is most common in the winter as it is wetter and our homes are less ventilated. This humidity is normally created by:

  • Leaking pipes
  • Condensation on windowsills
  • Steam from cooking or showering
  • Damp

Mould spores can be carried through the air, in water, and on animal fur, so it spreads around properties very quickly. It is important you tackle it as soon as you spot it as it is dangerous to live with.

The health hazards associated with mould

Mould produces allergens which trigger allergic reactions when inhaled or touched, like a runny nose or a skin rash. It could also trigger asthma attacks.

Living with mould also leaves you more susceptible to health conditions, like respiratory problems. The symptoms include a tight chest, trouble breathing, and coughing. Long-term exposure can make this progress into a respiratory infection.

It could also put you at risk of mould toxicity, a condition that occurs when toxins from mould accumulate in the body. This can trigger more serious problems, like depression, anxiety, and insomnia.

Some groups are more vulnerable than others, like babies, young children, and elderly people, as well as people with skin conditions, respiratory problems, and weakened immune systems. You can find out more about the dangers here.  

Why does mould keep coming back?

Normally, it is because people don’t fix the cause of the mould. For example: if mould that has been treated in your bathroom quickly returns, it is probably because you are not ventilating the room properly after a shower. Remediation specialists will help you diagnose the problem.

Another reason it comes back is that people often try to clean the mould themselves. Home remedies typically tend to only remove the visible spores so the mould can still grow. Or, if you scrub the mould, you will release spores into the air and help it spread.

It might also not be getting rid of all of the mould. It starts growing in hidden, humid areas, like behind walls, or in crawl spaces. Fail to tackle the difficult-to-reach spores, and it will continue to spread around your property.

Professional cleaners know how to detect mould in walls and hidden spaces, and will have the right equipment and products to get rid of it.

How to get rid of mould permanently

You need to start by determining what the cause is. See where mould is most prevalent, identify humid spots in your property, and check regularly for areas with lots of excess moisture. Once you have determined the problem, get it sorted.

Next, bring in professional cleaners with training in mould remediation, the right PPE to keep themselves safe, and specialist equipment and products to remove it. You should never attempt to clean mould yourself as you will not be tackling the problem, and could put your health at risk.

Once it has been taken care of, you need to prevent it from coming back. Here are some tips on how to do that:

  • Keep an eye on humidity levels in your home and make sure it is no higher than 50%. Consider purchasing a dehumidifier for problem areas in your home.
  • Make sure you ventilate the bathroom and kitchen when you are using them. Open windows, fit extractor fans, and shut doors so the steam can’t reach other parts of your home.
  • Fix leaks in your roof or plumbing as soon as you spot them to minimise the chance of damp.
  • If your home floods, it will need to be dried and deep cleaned as soon as possible. 
  • Avoid drying clothes indoors. The moisture from the clothes can easily settle on the walls and ceiling.
  • Don’t carpet rooms with high humidity, like bathrooms or basements. Carpets trap moisture, making them the perfect environment for mould to spread.
