What Causes Mould in Kitchens?

Mould is a hazard wherever it can be found, whether that is in your bathroom or your bedroom. Unfortunately, mould can grow anywhere, even in your kitchen.

This creates a serious health hazard as our kitchens are rooms which we use on a daily basis. Breathing in all of the moulds is nothing but trouble for you and your loved one’s health.

That is why at I-Sells we are dedicated to helping our blog readers and customers understand what they are dealing with, whilst offering solutions.

In this article, we will answer the question ‘What causes mould in kitchens?’

Let’s talk about mould and how it can affect you.

Should I be worried about mould?


Mould, otherwise known as damp, is a fungus that grows on wet surfaces. Mould comes in a variety of colours: Black, Green, Brown, Grey and White. It can be difficult to identify mould by colour as it can occur in many shades. Some of the most common mould strains in the home are:

  • Black Mould – Also called Stachybotrys chartarum, Black mould is commonly found in bathrooms and wet rooms but can also result in mould in bedrooms where there are cold exterior walls.
  • Cladosporium – Commonly found in bathrooms, under sinks, and around faucets but it can grow on surfaces like carpets, furniture, walls, and floors.

Mould reproduces from tiny spores. The spores float through the air and deposit on the surfaces. Under adequate temperature, moisture, and nutrient conditions, the spores can form new mould colonies.

Mould can severely affect your immune and respiratory system, as the spores are easily breathable and not prominent enough to see through the human eye.

People with allergies may be more sensitive to moulds. People with immune suppression or underlying lung disease are more susceptible to fungal infections.

Individuals with chronic respiratory disease may experience difficulty breathing. Reactions vary from fever, a cough, red or itchy eyes, marks on the skin and much more.

If you or your family members have these conditions, a qualified medical clinician should be consulted for diagnosis and treatment.

Mould in your kitchen is a particularly dangerous hazard due to the fact the spores can easily land on any food or drink. In regards to the food, it could accelerate its moulding, wasting your money as well as causing a health risk.

One of the causes of mould


Mould in your home generally occurs as a result of condensation.

Condensation occurs when heat and moisture in the air are confined to a certain area, as this heat tries and fails to escape, droplets of water are created on cold surfaces. A good way to think about this is having a hot shower on a cold day and not opening your window.

The reason condensation creates mould is that a damp and humid environment is the optimum condition for mould to grow. Especially in your kitchen – hence why mould in kitchens is a common occurrence. A room which generally sees a large amount of condensation.

The true danger of mould is that its particles can travel through the air without us seeing them.

That being said, condensation is not the only cause of mould, it can occur from leaks in the structure of a building too.

So how does this relate to mould in kitchens?

Humidity and eventually condensation can occur in a kitchen for a variety of reasons, which eventually leads to mould. These are just a few contributors:

Not using the extractor fan or hob extractor

A hob extractor is made specifically for the foods and various other things you use your hob for, a byproduct of cooking/boiling is steam. Sometimes hobs are far from windows, which is where a hob extractor comes in handy.

On the other hand, using a kitchen extractor fan will help remove any humidity that has built up indirectly as a result of using the kitchen and its appliances.

Using both of these appliances in conjunction will help the removal of condensation and thereby mould in kitchens.

Keeping the room unventilated

Not opening a window will not help regulate the temperature of the room when you cook or boil food. This can be made worse when neglecting to use a kitchen extractor fan in conjunction with window ventilation and making use of a hob extractor thereby exacerbating the growth of mould in kitchens.


Structural issues in a building can cause moisture to travel through an outside wall to the inside, this in conjunction with fluctuating temperatures inside and outside, along with the condensation created in the kitchen can cause mould in kitchens to develop.

If you want to know how to reduce condensation in your home, take a read at our blog which has all the information you need here.

If you have found mould in kitchens, or any room in your home, you need to assess if this is your landlord’s responsibility (for example it could be from a leaking roof that needs repairing). Or if the dampness is caused by improper ventilation. To assess your options, click here.
