How To Get Rid Of Mould For GOOD: Causes, Prevention & Treatments

Mould can appear in our homes almost by magic, especially in the colder months. If you feel like you're fighting a losing battle with damp and mould in your home, don't fret. The causes can be surprisingly simple and are thankfully, fairly easy to remedy.

Expert Home Tips are here to help you to win the battle over mould in your property! Today we're sharing the best prevention and treatment methods to rid your home of it for good.

What causes mould & damp?

1. Moisture inside of your property

Do you realise how much moisture is in your home?

The most common cause of damp comes from moisture inside of your home. You might not realise how much water is produced from the simplest of tasks. Things like:

  • Having a shower or a bath
  • Cooking 
  • Boiling the kettle
  • Using a washing machine and tumble dryer
  • Air drying clothes
  • Even breathing!

In the colder months, all of this excess moisture can cause a lot of problems. If you don't have the windows open or don't have proper ventilation, the moisture has nowhere to escape. 

2. Your home is not effectively weatherproofed 

Mould and damp on the inside of your home, on exterior walls and on chimney breasts could be a telltale sign of a weatherproofing issue. Weatherproofing problems to keep an eye out for include: 

  • Leaking roofs
  • Damaged mortar 
  • Leaks from gutters

You'll most likely need to call in a professional to fix weatherproofing issues, but you might be able to clean up the inside mould and damp by yourself. 

3. Issues with plumbing

Is there mould near your radiator? 

If you've got mould forming near your ceilings, radiators, and sinks, it could be a sign of a plumbing issue. These can be caused by the pipes responsible for:

  • Your hot and cold water supply
  • Central heating
  • Wastewater

Contact a plumber if you are unable to fix the problem yourself. 

4. Rising damp

In older buildings, there isn't always a foundation between the ground and the wall structures so the materials used can easily absorb moisture. This can cause rising damp. You'll know if you're dealing with rising damp because you're likely to find mould in ground floor rooms only. 

Beware! A long-term fix f0r rising damp could be costly. 

Where does mould appear?

Identifying where the mould and damp are in your home could help you to identify the cause of the problem. 

1. Ceilings 

Check the corners of your bathroom!

When moisture rises, it can start to form as a dark mould in the corners of your ceilings. If your ceilings are discoloured or have yellow staining, it could be a sign of a weatherproofing issue. Pay close attention to the area near the top of your chimney breast and the corners near the exterior of your home. 

2. Walls 

The signs of mould and damp on walls include: 

  • Surface feeling cold and damp
  • Mould growing in dark, speckled patches
  • Flaking paint and curling wallpaper 

Mould and damp are able to spread across wood, wallpaper, and paint. Find out more about condensation on walls in our other article. 

3. Windows

Don't let mould ruin your house.

Check your windows every morning for condensation and small pools of water. You might also notice mould growing on the frames and silicone sealant as a result. If there's excessive condensation, it's a sign that your home has too much moisture trapped inside. 

4. Furniture & soft furnishings

In very extreme cases, you might even find mould on furniture and soft furnishings. Blinds and curtains near windows that have been affected by damp could have signs of mould developing on them. You might even find mould on the back of your sofa if it has been placed against a damp wall. 

To find out how to clean vertical blinds, check out our other guide. 

5. Bathrooms & kitchens

Even a kettle can do some damage.

Bathrooms and kitchens are likely to be your worst offenders when it comes to mould and mildew. With excess steam and water, damp can easily cling to the walls and windows. Check your grout and sealants for signs of mould, as these can be hard to repair once it takes hold. 

Preventing mould & damp

1. Ventilate the property

Try to keep windows open.

It might sound crazy in the winter months, but keeping your windows open wherever possible will make a big difference if your mould is caused by excess moisture inside the property.

After showering or cooking, open the window and turn on extractor fans. Close the doors to the kitchen and bathroom so that all of the excess moisture will be removed from those rooms and not spread around the rest of the house. 

You'll also want to make sure that washing machines and tumble dryers are fitted with adequate ventilation. 

2. Use the right paint

When decorating areas where moisture and damp are more prevalent, opt for paints that are cut out for mould and wet conditions. It's best to avoid using wallpaper in these areas as it will likely peel off or need replacing on a regular basis. 

3. Remove excess moisture

Suck up all of the water!

It's a good idea to regularly remove as much excess water and condensation as you can. You could use a cloth to wipe moisture off of windows, shower screens, and tiles, but a Karcher window vac will be much more efficient.

4. Put the heating on a regular temperature

Are you guilty of turning the heating from one extreme to the other? It's better for your home if you leave it at a regular, mid-range temperature. Too much fluctuation will cause moisture in the air to condense. 

5. Turn on fans

Do you remember to do this?

It might sound obvious, but it can be very easy to forget to do it. Before cooking and showering, turn on extractor fans. Make sure to leave them running for a good 10-20 minutes afterwards so that they can clear the air.

TOP TIP: Don't forget to replace the filters in your fans so they keep working properly. 

6. Maintain weatherproofing

We spend most of our time inside, so it can be hard to remember to look after what's outside! Make sure to regularly check up on things like guttering and tiles to make sure that you don't end up with any leaks.  

7. Use a dehumidifier

Liquid absorbed from moisture in the air!

A dehumidifier could help to reduce levels of moisture in your home drastically. You can purchase electric models or ones that soak up moisture using a replaceable absorber. You'll be amazed by how much water it collects!

8. Be wary of damp laundry

You might not think it's causing damp, but even a wet towel on a radiator can wreak havoc! Try not to overload towel warmers where possible.

You should also avoid leaving washing to air dry inside for as long as the weather allows. If you do dry it inside, put it in one room with the door closed and the window open. 

How to get rid of mould & damp

1. Take precautions 

Before you start treating the mould, you need to think about a few safety measures: 

  • Wear gloves, a mask to cover your nose and mouth and eye protection. 
  • Wear old clothing - mould removing products are likely to damage fabrics. 
  • Always follow the guidelines on the packaging of any products you're using.
  • Never try to remove mould that is larger than 1 metre square in size. Call in professionals to advise you. 
  • Keep your home well ventilated at all times. 
  • If the mould and damp are caused by sewage or contaminated water, don't attempt to clean it up yourself. 

2. Identify and fix the root problem

Treating mould won't be worth it unless you know how to stop it from coming back. You may need help from a professional to fix whatever the problem is, or it could be as simple as making sure you leave your windows open more often. 

If you're experiencing damp, you might also notice the presence of silverfish. This is an indicator that you have an underlying damp problem, as they are attracted to moist conditions. 

3. Treat the mould

Spray a mould removing spray onto the surface you want to treat. Carry out a spot test in an inconspicuous area first, as these types of cleaners can damage some surfaces. Use an old cloth to wipe the solution off, following the instructions that are given on your particular product. 

4. Redecorate 

Now that you know the problem won't persist, you should be safe to redecorate any spots that have been affected. If painting, it's worth applying a coat of a mould resistant paint and then going over the top of that with your chosen colour.  

5. Redo sealants


Sealants aren't the best at resisting mould, so you'll likely have to redo them. Allow the sealant to dry and then use a knife blade to cut away the silicon. Apply some fresh sealant and allow to dry before you let the surface become wet again.  

Now that you've sorted the mould and damp, let's tackle bathroom odours. Read our article on shower onions to find out about this strange phenomenon.

    I'm sorry but all that info is useless to me. We've been living with damp and mould for years. We've tried everything out there to try and treat and beat the problem, and so far found nothing that actually works. People say the same as you, keep your heating on. But what about the people who can't afford to do that? Millions live below the breadline, yet no-one helps them with it. What can they do when nothing works?

    1. Author Joanne A on December 14, 2018 at 9:57 am

      Sorry to hear that, Mailea. Unfortunately keeping mould at bay can be a very costly task. It's a shame that so many people have to live with it, as it can be really bad for your health. If you rent or live in a council house it would be advisable to contact whoever owns the property to see if they can resolve the issue. It should be their legal duty to keep the property safe for you to live in.

      I only heat one room due to cost and the two bedrooms upstairs no heat I have no mould because I keep the bedroom windows open all day even in winter slightly to keep airflow and then shut at bight and I leave my clothes horse for drying upstairs yes it takes time to dry and thus have to be organised

    3. Author Joanne A on December 14, 2018 at 2:19 pm

      Sounds like you've got a great system going on, Caroline! Drying clothes is a real pain in the winter, isn't it?

      There is an interesting article from a recent issue of 'What The Doctors Don't Tell You' about the effects of mould on your health. I gave a photocopy to friends who have a severe mould problem. They are using it as leverage to try and get their landlord to sort it out. They cannot use one bedroom as the problem is so bad. leaving the heating on is not an option.

    White vinegar works well to keep mould at bay. Apply undiluted on to affected areas as soon as you see it appearing and you'll keep the place free from unsightly mould. The smell of vinegar fades away fairly quickly too.

      Great tip! Thanks Denise.

    1. Author Joanne A on January 27, 2020 at 2:53 pm

      Thanks for sharing! Some would avoid bleach as it can feed mould.

    2. Author Linda Walters on January 20, 2023 at 9:21 am

      I had a damp patch and was told to wipe it with bleach and it definitely works on the silicone round windows, I also bought an additive which I put in the paint

    3. Author Joanne A on January 24, 2023 at 12:10 pm

      Be careful, as bleach can discolour the silicone and may cause it to deteriorate over time.

  6. Author James on January 29, 2020 at 8:24 am

    When replacing sealants, purchase anti-mould products, they are well worth the increased cost.

    1. Author Joanne A on January 29, 2020 at 11:42 am

      Definitely! Thanks for sharing, James!

  7. Author Barbara on January 29, 2020 at 9:21 am

    I use bleach diluted to wash walls down and it works

    1. Author Joanne A on January 29, 2020 at 11:39 am

      Thanks for sharing, Barbara! Does it grow back?

    My house is so damp the next door neighbours don’t look after their house so I’m getting damp from both sides. I use the little dehumidifier which is the chalk crystals the the amount of water the collect are unbelievable. I also use the ones you can hand in the wardrobe I have them all over the house. I also have a large dehumidifier in the bathroom for when we have showers and bath. My windowsills were covered in mould so how I cleaned them was with bleach and a toothbrush. Time consuming but they are gleaming ....

    1. Author Joanne A on January 30, 2020 at 11:56 am

      It's important to keep on top of it! Shame about your neighbours.

  9. Author Tracey on June 1, 2020 at 12:57 pm

    Cotton wool stretched into “sausages” and soaked in bleach then packed along windows on top of the sealant works well. You need to leave it overnight and then wash away with warm soapy cloth. Make sure you wear gloves and that the area is well ventilated!

    1. Author Joanne A on June 2, 2020 at 11:18 am

      Fantastic idea - thanks, Tracey!
