How Do I Know If I Need Professional Mould Removal or If I Can Clean It Myself?

Mould is more than just an eyesore—it’s a potential health hazard and a sign of underlying moisture problems in your home. As mould removal specialists at Mould Pro, one of the most common questions we hear is: “Can I clean this mould myself, or do I need a professional?”

The answer depends on several factors: the extent of the mould, the cause, the location, and your health concerns. Let’s break it down so you know when to roll up your sleeves and when to call in the pros.

✅ When DIY Mould Cleaning May Be Okay:

If you spot a small amount of mould on a non-porous surface like tiles, glass, or metal, and it covers an area less than 1 square metre, you may be able to clean it yourself.

DIY Tips for Small Mould Issues:

Wear gloves, a mask, and goggles.

Use white vinegar or a mild detergent with warm water.

Scrub the area thoroughly and dry it completely.

But be cautious—surface cleaning won’t fix underlying moisture problems or kill hidden spores.

❌ When You Should Call a Professional:

Widespread Mould (Over 1m²)

If mould has spread across walls, ceilings, or multiple rooms, it likely indicates a larger issue such as water leaks or poor ventilation.

Mould on Porous Materials

Mould growing on drywall, timber, carpets, or insulation often penetrates deep into the material. Surface cleaning won’t stop the spread.

Reoccurring Mould

If mould keeps coming back after you clean it, there’s likely a hidden moisture source or ineffective DIY treatment.

Health Symptoms

If anyone in your home experiences allergies, asthma, or respiratory issues, even low levels of mould can be dangerous. Professional removal reduces exposure risks.
