Have you ever walked into a room and been hit with a musty, damp smell that just won’t go away? That odor is often a red flag that mould could be lurking somewhere out of sight. Many homeowners in Perth experience this issue, especially during humid months or after heavy rainfall. Ignoring the smell might lead to bigger problems down the road, including property damage and health risks. If you’ve noticed an unexplained musty scent in your home or business, it’s time to consider professional Mould Detection in Perth to identify and address the issue before it worsens.
Why Does Mould Have a Musty Smell?
Mould produces microbial volatile organic compounds (MVOCs) as it grows and spreads. These compounds are responsible for that distinctive musty odor, which many describe as earthy, stale, or even similar to rotting wood. Since mould thrives in damp, poorly ventilated spaces, the smell is often a strong indicator of excess moisture and hidden mould growth.
In many cases, mould can be concealed behind walls, under carpets, inside ceiling cavities, or within air conditioning systems. The musty smell serves as a warning sign that something is wrong, even if you can’t see visible mould. When you notice persistent odors that don’t disappear with cleaning or ventilation, it’s crucial to seek expert Mould Detection in Perth to pinpoint the exact source of the problem.
Common Hidden Mould Locations
Since mould prefers dark and damp environments, it can grow undetected in several areas of a home or workplace. Some of the most common places where hidden mould develops include:
-
Behind walls and wallpaper – Leaking pipes or condensation inside walls can create an ideal breeding ground for mould.
-
Under carpets and flooring – Spills, leaks, or high humidity can lead to mould growth beneath carpets, floorboards, and tiles.
-
Inside ceiling cavities – Poor ventilation and roof leaks can cause mould to spread above ceilings.
-
Behind kitchen and bathroom cabinets – Water leaks from sinks or plumbing issues often lead to mould in these hidden areas.
-
In air conditioning systems – Mould spores can thrive in HVAC units and ductwork, spreading through indoor air.
If you suspect mould but can’t see it, a professional Mould Detection in Perth service can conduct a thorough inspection, using moisture meters, thermal imaging, and air sampling to locate hidden mould infestations.
Health Risks of Hidden Mould
Exposure to mould can have serious health consequences, especially for individuals with respiratory conditions, allergies, or weakened immune systems. Even if you don’t have pre-existing health issues, prolonged exposure to mould spores can lead to symptoms such as:
-
Persistent coughing or wheezing
-
Nasal congestion and sinus irritation
-
Skin rashes and eye irritation
-
Headaches and fatigue
Mould exposure can be particularly harmful to young children, the elderly, and those with asthma or respiratory illnesses. Addressing mould early through expert Mould Detection in Perth can help reduce health risks and improve indoor air quality.
What to Do If You Smell Mould
If you notice a musty smell in your home or office, take the following steps:
-
Inspect for visible signs of mould – Check walls, ceilings, and damp areas for discoloration or black spots.
-
Monitor humidity levels – Use a hygrometer to measure indoor humidity, aiming for levels below 60%.
-
Improve ventilation – Open windows, use exhaust fans, and dehumidifiers to reduce excess moisture.
-
Seek professional mould inspection – A trained specialist can detect hidden mould and recommend appropriate remediation methods.
