8 Warning Signs That Your Home May Have a Mould Problem

Published March 30

Do you ever notice a musty smell coming from your home, see an unfamiliar black spot on the wall, or peeling wallpaper, yet can’t pinpoint the cause? Chances are it could be due to mould –a common problem that isn’t always easy to spot and doesn’t just arise from poor housekeeping. Mould can exist in unexpected places, even in impeccably spotless homes, so it is essential to know where to check for mould in the house. 

Mould is a common problem many homeowners face. It is not easy to detect until it has spread throughout the home. Mould not only damages the structural integrity of your home, but it can also have a significant impact on indoor air quality that can cause various health problems, particularly for those people with allergies or respiratory issues. 

Performing small checks around your home can ensure you keep anything dangerous – like unseen mould growth – under control. In this article, we’ll look at eight warning signs of mould in your house and what steps you should take immediately to eliminate them.

  1. Visible Mould Growth: The most obvious sign of a mould problem is the presence of visible mould spores. Look for fuzzy, green, black, or white growth on walls, ceilings, or floors.
  2. Musty Odour: If you notice a strong, musty odour in your home, it could be a sign of mould growth. The air quality problems due to moulds may be most noticeable in areas with poor ventilation, such as basements or attics.
  3. Water Damage: Stains on walls or ceilings, predominantly brown or yellow, can indicate water damage and potential mould growth. Any areas in your home that have suffered water damage, such as from a leaky roof or flooding, are at high risk for mould growth.
  4. Allergic Reactions: You could be getting sick from mould in your house. If you or anyone in your family has developed allergic reactions such as sneezing, coughing, or itchy eyes, it could be a sign of mould growth in your home. Moulds release spores into the air, which can cause respiratory problems when inhaled. These spores can also exacerbate existing conditions such as asthma and allergies. 
  5. Peeling or bubbling paint or wallpaper: Mould can grow behind wallpaper or paint, causing it to peel or bubble.
  6. Condensation: Condensation on windows or walls can create a moist environment conducive to mould growth.
  7. High Humidity: If the humidity in your home is consistently above 60%, it can create conditions that are favourable for mould growth.
  8. Structural damage: Moulds can weaken structures over time, leading to potential collapse or other damage.

Remember that maintaining a healthy home also involves proactive behaviour such as monitoring dust levels, checking for signs of water damage regularly and taking notice of any strange odours that may arise – all clues that could indicate an existing or imminent mould problem.
