Know the Tell-Tale Signs of Drywall Mould

When it comes to keeping your home safe and healthy, it's important to be aware of the tell-tale signs of mould growth. Mould can be a serious problem in any home, but it's especially dangerous when it starts growing on drywall. This is because drywall is a porous material that easily absorbs moisture, making it a prime breeding ground for mould.

From discoloured walls to musty odours, drywall mould can cause all sorts of problems for homeowners. It's important to be aware of the signs and take action immediately if you notice any of them in your home.


By understanding the tell-tale signs of drywall mould and taking steps to prevent it from growing in your home, you can help keep your family safe and your home healthy.

Spotting the Tell-Tale Signs of Drywall Mould

Sign #1: A Damp Smell Permeating in Your Home

One of the first signs of drywall mould is a damp, musty smell permeating your home. This smell is usually caused by moisture in the air, which can be from a combination of too much humidity, condensation, or a water leak. If you notice a persistent damp smell in your home, it is important to investigate the cause and take action to reduce the moisture.


Sign #2: Discoloration on Your Walls

Another tell-tale sign of drywall mould is discolouration on your walls. This discolouration can be in the form of yellow, green, or black spots, or other discoloured patches. These discolourations are caused by the mould growing on the surface of the drywall and can be indicative of a larger mould problem. If you spot any discolouration on your walls, it is important to investigate further to determine the cause and take action to remove the mould.


Sign #3: Peeling Paint or Wallpaper

Mould can also cause paint or wallpaper to peel away from the wall. This is because the mould can cause the surface of the wall to become damp, which can cause the paint or wallpaper to become loose and start to peel away. If you notice any peeling paint or wallpaper, it is important to investigate the cause and take action to remove the mould and repair the wall.


Sign #4: Recurring Black Streaks, Specks, or Dots

One of the most common signs of drywall mould is recurring black streaks, specks, or dots on the wall. These dark spots are usually caused by moisture seeping through the drywall, which can happen if the drywall is exposed to a leaking pipe or a humid environment. If you notice any of these dark spots on your walls, it’s important to take action to address the issue.


If you’re not sure if the spots are caused by mould, you can test them by lightly wiping the area with a damp cloth. If the spots smear or turn darker, then it’s likely that mould is present.


Sign #5: Bulging Spots

Bulging spots will be an indication that moisture has been trapped in the wall, which can lead to mould growth. Bulging spots can be caused by a variety of issues, including high humidity, water leaks, or inadequate ventilation. It’s important to take these signs seriously and address the issue quickly before the mould spreads.
