Mold on walls can cause several health issues. These include asthma, migraines and allergies. Black mold is even worse for health. Spores drift in the air and attack the respiratory system, skin, and may even cause infertility.

In this post, we’ll discuss what causes mold, and the giveaway symptoms that you’ve got mold. You’ll also learn how to remove mold from your walls.

How does mold take hold?

The most common cause of mold is a small leak. This might be in the roof, or caused by a blocked gutter, or a crack in a water pipe. It may also be caused by excessive condensation in the home – for example, in the bathroom or kitchen, or excessively warm bedroom. When moisture becomes trapped, humidity provides the ideal conditions for mold growth. 

Some of the most common areas in your home where mold might grow are its walls, particularly drywall and wallpapered walls. When mold takes hold, it can spread at a colossal speed.

What are the symptoms of mold in the home?

There are a couple of signs you may have mold, even if you can’t see it. These are:

  • A musty smell, which is usually the first sign that your home has a mold problem
  • An increase in family allergies or illness

These early warning signs are prompts for action. Mold can hide behind drywall before bursting out. It can be difficult to locate at this stage, so a professional inspection would be advisable.

At a more advanced stage, you’ll notice water spots, discoloring, and mold growth on your walls. Cracked and peeling paintwork could be a sign that mold is behind your walls.

How to get rid of mold on walls

Before you get started with the mold removal, remove all items that have been affected. These might include carpets, though you may be able to remove mold from your carpet if the infection is not too bad. Some furniture may have to be thrown away, too.

Once you’ve cleaned the area, it’s time to start the process of removing mold from your walls. Drywall that has bowed or is covered with black mold will probably need replacing. If the wall is sound, you can start.

Cover remaining furniture, carpets and flooring with plastic sheeting. This will protect against any spillage of cleaning chemicals.

Apply a solution of one part bleach to three parts water to the wall using a sponge. Wear waterproof rubber gloves to do so, and a mask to ensure you don’t breathe in any displaced mold spores. Gently wipe away the mold, rinse and dry.

Once the wall is clean of mold, prime it with a sealer and paint over to match the surrounding wall.

Prevent the mold from returning

Once you have got rid of mold from your wall, you should take precautions to prevent its return. These include:

  • Using dehumidifiers to keep indoor humidity low
  • Monitoring and controlling humidity to below 55%
  • Fixing all leaks in the home, including pipes and tubes
  • Keeping your gutters clean and blockage-free
  • Wiping down bathroom walls
  • Opening windows to keep rooms ventilated
