How to Detect Mold in Your Home

Mould in your home is more than just an eyesore — it’s a health hazard that can trigger allergies, respiratory problems, and even structural damage. Detecting mould early is essential for protecting your family and your property. In this guide, we’ll explain how to detect mould in your home, what symptoms to look for, and when professional mould testing is needed.

Common Signs of Mould in Your Home

• Musty odours: A persistent damp smell often signals hidden mould.
• Visible growth: Black, green, or white spots on walls, ceilings, or windows.
• Water damage: Past leaks or flooding can create the perfect conditions for mould.
• Health symptoms: Sneezing, coughing, or headaches that worsen indoors may indicate mould exposure.

How to Test for Mold at Home

While DIY mould test kits exist, they’re often unreliable. Professional testing ensures accuracy and helps identify the type of mould present.

Methods include:

• Air quality testing: Detects spores not visible to the naked eye.
• Surface swab tests: Identifies mould on walls, ceilings, or furniture.
• Moisture mapping: Locates hidden leaks that may be fuelling mould growth.

Mould in House Symptoms to Watch Out For

Exposure to mould can cause:

• Allergic reactions (sneezing, watery eyes, rashes)
• Respiratory issues (asthma flare-ups, chronic coughing)
• Fatigue and headaches
• In severe cases, long-term health complications
