Mould in the bathroom is one of the most common complaints for tenants. It’s no surprise why – they contain the perfect conditions for the fungus to grow and spread. The moment you spot any in your property, you must bring in professional cleaners to remove it.

Here at ICE Cleaning, we offer quick, thorough mould removal services. Our Dewpoint-accredited technicians can eliminate all the mould from the surfaces and the air, and make your property a safe place to live. They can be on site in a matter of hours in an emergency.

Keep reading to find out how to get rid of mould in your bathroom, and prevent it in the future.

What causes mould in bathrooms?

Mould grows in damp, humid, poorly ventilated places, and thrives in dark areas. Bathrooms normally tick all these boxes for lots of different reasons:

  • When the tap or shower is used, the steam condenses on the walls, ceiling, and floor, and makes the air very humid
  • Bathrooms are normally quite poorly ventilated, especially if the fan is off, so the humid air cannot leave
  • Leaky pipes, toilets, and taps may make plasterboard and wood damp

You can normally find it growing on the bathroom wall, ceiling, shower curtain, and in grout and silicone sealant. The latter two are particularly susceptible to mould.

Grout is a porous material that easily absorbs and retain water so it can stay damp for a long time, making it the perfect place for it to grow. When cracks and gaps appear in your silicone sealant, moisture could seep in and mould might start growing behind it.

Why you must have mould removed

Mould is very dangerous to live with. It releases allergens, irritants, and occasionally toxins. Should you inhale, touch, or ingest the spores, you may have an allergic reaction, such as sneezing, a runny nose, and a cough. It can even cause asthma attacks.

Young people, elderly people, and people with pre-existing health conditions or weakened immune systems are more sensitive to mould exposure. Long-term exposure causes more severe health problems, including respiratory issues, organ damage, and asthma.

Given how small and poorly ventilated bathrooms normally are, and how much we use them, you are at risk of a lot of mould exposure. 

How to get rid of mould

Although there are lots of products on the shelves, and DIY methods online, you should never try mould removal yourself.

Firstly, when you scrub mould, you release spores into the air and could inhale them. You are also more likely to touch them when wiping it down.

You will probably just remove the visible, surface spores, too. The unsightly mould may be gone, but there might be more that you have not tackled, which can continue to grow and spread.

Only professional cleaners with personal protective equipment to keep themselves safe, and specialist products and equipment can properly clean up mould. They will be able to remove all traces of it so it can’t come back.

How to prevent mould in bathrooms

Although mould could become a big problem in your bathroom, there are lots of little changes you should make that will ensure it can’t thrive there, anymore. You can find out more about stopping mould coming back in this blog.

  • Ventilate the bathroom after a shower or bath: Open the window or run the extraction fan to get rid of any humid air and steam. Don’t forget to keep the door shut, too, so the humidity does not travel around the house and cause mould elsewhere.
  • Wipe down condensation: Remove as much condensation as possible following a shower or bath. Focus on grout and silicone, shower trays, and anywhere else water collects.
  • Decorate with some purifying plants: Some house plants lower the humidity in the air by absorbing moisture through their leaves, and can even eliminate airborne mould.
  • Regularly clean your bathroom: shower curtains, curtain liners, and bathmats can be breeding grounds for mould, so wash them frequently.
  • Don’t leave wet towels on the floor: Make sure you also wash them regularly, and dry them in well-ventilated areas
