Mould growing in the corner of a wall CONTENTS

Winter's colder, wetter weather provides mould with the perfect conditions to start growing. One of the most common places to find it in your home this time of year is in the bedroom. Mould is not just an unsightly nuisance - it presents a real risk to your health. 

At ICE Cleaning, we offer fast, long-lasting mould remediation services. Our technicians are accredited by Dewpoint Professional and can remove all traces of mould from your home, including from the air and hard surfaces. We are available nationwide, 24/7, 365 days a year. 

Read on to find out what causes mould in your bedroom and how to prevent it growing there in the future. 

What causes mould to grow in the bedroom?

Mould grows in environments that contain excess moisture, oxygen, and organic materials. It is typically caused by damp, condensation, high humidity, and poor ventilation in a property. 

Bedrooms, particularly those with ensuite bathrooms or inadequate heating systems, tend to provide mould with the perfect conditions for growth. 

  • Steam from the bathroom can spread into the bedroom, leading to condensation on windows and walls
  • We exhale half a pint of water as we sleep in the form of vapour which can make the air humid
  • Mould often grows in wardrobes and closets due to poor ventilation and still-damp clothes which could spread across the room
  • There is lots of organic material available for mould to grow on like upholstery, clothes, and furniture

Come winter time, mould can get worse as we keep our windows shut which results in poor ventilation and lots of condensation

The dangers of mould in the bedroom

Firstly, mould releases spores into the air which can lead to respiratory issues including asthma and allergic reactions. For people with existing health problems like skin and respiratory conditions or a weakened immune system, and elderly or young people, mould exposure can be especially harmful. 

Secondly, exposure to certain types of mould, such as black mould which can produce toxic substances, has been linked to more severe conditions including sick building syndrome.

Mould can damage your property, too, as it feeds off organic materials. Your bedding, clothes, upholstery, and certain types of furniture could slowly deteriorate over time. Should it spread to building materials, it could have more significant and dangerous effects. 

How to get rid of mould in the bedroom

When people spot mould growing in their home, their first instinct is to treat it with a mould remover or a DIY mould removal technique they saw online. But these products and methods are usually not that effective and can be too harsh for certain surfaces. 

Bleach, for example, can lighten fabric or paint, and is dangerous to use without sufficient personal protective equipment (PPE) or proper ventilation. 

Using the wrong method could even make your mould problem worse. Scrubbing the mould can aggravate it, and cause it to release spores that travel around your property until they start growing on a new surface. If you do not remove all of the mould, it will just grow back. 

Just as mould is harmful to be exposed to, cleaning it might also put your health at risk. PPE is required to ensure you don't touch, inhale, or ingest any of the mould during the cleaning process. 

The safest, most effective way to remove mould is by hiring professional mould cleaners. They have all the necessary tools and experience needed for remediation. Mould experts can even pinpoint the specific cause of the mould in your bedroom and advise on how to prevent it returning in the future. 

How to prevent mould in the bedroom

Controlling humidity is a key factor in stopping mould. Consider purchasing a dehumidifier and make sure you keep the humidity level below 50% throughout the day. 

Another essential tip is good ventilation. Keep windows open when possible or use fans to improve air circulation. If it's too cold outside, crack the window slightly open or open trickle vents regularly to let fresh air circulate without making your room too cold.

Mould thrives on organic materials like wood, fabric, dust, and dead bugs, so regular cleaning of furniture and bedding will discourage its growth. Don’t forget about your carpets as they are often overlooked hotspots for spores.

If you have an ensuite bathroom, keep the door shut while washing to prevent steam and humid air entering your bedroom. You should also keep the bathroom well-ventilated and install a fan to get rid of any steam produced. 

Keep the heating on as well as letting your property cool down entirely can make surfaces cold and increase the likelihood of condensation.
