Whether you have a full-blown outbreak or small patches and spots on your wall, mold growths are quite unsightly. But the unpleasant looks asides could also constitute a health hazard through the release of allergens into the air and potentially dangerous toxins. Mold issues could also suggest a much deeper problem, such as water damage to your walls. This is why learning how to get rid of the mold of walls is important.

How To Get Rid Of Mold On Walls? Tips & Removal Method

If you notice any mold growth on your walls (even if it is just a small patch), it is recommended that you take action immediately. Molds spread quickly and can become a much bigger issue that is difficult to get rid of once it does. In this article, we will cover some simple tips for getting rid of molds on your walls and how to do it properly.

Tips for Getting Rid Of Mold on Walls

If you have a severe problem or widespread mold infestation, getting rid of it is not quite easy. Trying to remove molds on your own is potentially hazardous. In such cases, it is advisable to contact a mold removal professional to help remove the mold safely.

However, if you intend to get rid of molds on your own, the following are some of the important steps to follow:

1. Identify the cause of the mold problem

This is arguably the most important step in removing mold on your walls. It is not enough to only wipe off molds with bleach. Sooner or later, the mold problem will arise again if the underlying cause is not fixed. This would mean repairing the source of water damage, fixing indoor humidity, and ventilating your space.

2. Fix moisture problems

Moisture problems caused by leaky pipes, broken windows, and poor drainage can create waterlogged areas which are perfect spaces for molds to thrive. You should fix structural damage like this immediately before you begin mold removal. If you don’t, you are likely to end up with the same issue again. Call a plumber or any other professional contractor you might need depending on the damage you are handling.

3. Reduce humidity

High humidity environments allow mold spores to grow. Hence, reducing humidity is one of the most important strategies to fix the moisture problem. Sometimes, fixing humidity problems could be as simple as ventilating your space. In other cases, you may need to install an air conditioner or exhaust fan. You can also consider installing a dehumidifier in high moisture areas such as bathrooms, kitchens, attics, and basements, where mold problems are likely to begin first.

4. Prevent Condensation

Moisture problems may also result from high condensation. You should take steps to mitigate this by insulating your walls and roofs. Walls, roofs, and pipes should also be insulated to prevent moisture from condensing on them, which may result in mold growth.

5. Mold removal products to consider

Mold problems are relatively easy to handle if it only covers a small area of your wall. There are various household products to do this effectively. Some of the most popular options that are effective for getting the job done include; borax, baking soda, vinegar, tea tree oil, hydrogen peroxide, and of course bleach. Below are the explanation of the various mold removal agents you can use:

  • Borax: 

You can prepare a borax mixture for removing molds by mixing a cup of borax with a gallon of hot water. Shake the mixture well to dissolve the borax and pour this solution into a spray bottle to be applied to the affected area. Do not rinse off the solution after applying it to the wall. This will prevent the molds from returning as long as you have fixed the underlying cause of the issue. 

  • Vinegar and Baking Soda: 

White vinegar is an effective solution for killing mold spores. It can penetrate deep into porous materials to kill molds at their root. Spray undiluted vinegar on the wall and leave for an hour before wiping the area with a sponge and warm water. You can also scrub the wall with baking soda solution. This solution kills mold and can also help get rid of the musty smell they cause. 

  • Tea Tree Oil: 

This product has antifungal properties and can help get rid of molds. A teaspoon of tea tree oil in two cups of water is an effective solution for getting rid of mold in the affected area. There’s no need to rinse off the solution, as it helps to keep mold away from walls for a long time. Tea tree oil is recommended for removing mold on painted or wallpapered walls. 

  • Grapefruit Seed Extract: 

The citric acid in grapefruit extract is another natural mold killer. It also doubles as a deodorizer. You need just 10 drops of grapefruit seed extract in a cup of water to prepare a mold removal solution that works 

  • Bleach: 

This is the go-to solution for getting rid of mold for most people. Bleach is effective when you need to remove molds on non-porous walls. However, it cannot penetrate porous surfaces. Bleach can also discolor wall surfaces or damage the finishing. One part of bleach in three parts of water should get rid of most mold types effectively. Leave the solution on for about 10 minutes before rinsing off. Preferential precaution should adhere when handling bleach, such as wearing safety masks and ensuring the room is well ventilated

  • Hydrogen Peroxide and Vinegar:  

A mixture of hydrogen peroxide and vinegar also makes an excellent mold-killing solution. One major advantage of this solution is that it does not give off toxic fumes like bleach or leave any residue behind. It can also get into porous surfaces to penetrate molds deep into the root. 

How To Removing Mold from Different Surfaces

Once you have identified the root cause of the mold problem and you have fixed it, you can now proceed to get rid of the mold problem itself. In many cases, the infestation is worse than the visible patch of mold you can see. In many cases, your first attempt may only get rid of the body of the fungus, while the hidden roots will remain to allow the mold to grow again after some time. Understanding the different wall types and the right way to handle them is essential for effectively removing molds once and for all. Understanding different types of wall surfaces also help to get rid of the mold problem without damaging the wall. 

Removing molds from dry walls:

Removing molds from drywalls is a little tricky because the drywall can get damaged if it becomes too wet. It is easier to just cut off the infected section of the wall rather than try to remove it. However, a mixture of hydrogen peroxide and vinegar can still get the job done. Be careful not to get the wall too wet and only use wipes instead of a tough brush. 

Removing mold from wood:

The porosity of wooden surfaces makes it difficult to get rid of mold effectively. Woods may also get stained by bleach and other harsh chemicals. A mixture of soap and borax is recommended for cleaning wooden surfaces. This mixture will also penetrate the wood better and get down to the root of the mold.

If the wood surface is painted, it can form a protective coating that prevents the mold problem from getting too deep and makes cleanup easier. You can use a mixture of hydrogen peroxide and vinegar safely on painted wood.


Getting rid of mold problems can be difficult and frustrating. If the mold problem is significant, it is best to hire a professional to handle it. They will follow strict remediation procedures that involve identifying the mold, assessing the extent of damage, and create a plan to remove the mold and prevent future mold infestations. Taking steps to prevent a mold problem from developing at all costs is even more recommended. This includes fixing plumbing issues promptly, ventilating your home, and installing a dehumidifier.
