The Ultimate Guide to Mould Removal

By Nic Bohanna on March 26th, 2025

Mould is more than just an eyesore, it’s a serious problem that can affect your health and damage your property. Whether it’s a small patch on the bathroom ceiling or a larger infestation spreading across your walls, tackling mould quickly is crucial. Left untreated, mould can lead to respiratory issues, allergies and structural damage. 

What Causes Mould Growth? 

Mould thrives in damp and humid conditions. If there’s moisture in your home, whether from leaks, condensation or poor ventilation, mould can start growing in as little as 24 to 48 hours. The most common causes of mould include: 

High humidity: Homes with excessive moisture in the air create ideal conditions for mould to develop, especially in bathrooms and kitchens. 

Leaks and water damage: Roof leaks, plumbing issues and damp basements contribute to long-term mould growth. 

Condensation: When warm air meets cold surfaces, moisture forms, providing the perfect breeding ground for mould. 

Poor ventilation: Without proper airflow, moisture gets trapped inside, leading to damp conditions that encourage mould growth.

Why is Mould Dangerous? 

The spores released by mould can trigger allergic reactions, asthma attacks and respiratory infections. Those with weakened immune systems, children and the elderly are particularly vulnerable. 

Common symptoms caused by mould exposure include sneezing, coughing, skin irritation, eye redness and difficulty breathing. If you notice persistent cold-like symptoms that improve when you leave home, mould could be the culprit. 

Beyond health concerns, mould can also cause damage to your property. It weakens walls, ceilings and flooring. In severe cases, it can compromise the structural integrity of a building. Addressing the issue as soon as possible is essential to prevent costly repairs. 

How Do You Remove Mould Safely 

If you’ve spotted mould in your home, taking the right steps to remove it is essential. While small patches can often be tackled using DIY methods, larger infestations require professional treatment

Step 1: Identify the Source of Moisture 

Mould will continue to grow unless the moisture problem is resolved. Identify leaks, condensation areas or humidity issues and address them before starting the cleaning process. 

Step 2: Gather the Right Equipment 

When dealing with mould, it’s important to protect yourself. Wear gloves, a face mask and safety goggles to prevent exposure to spores. Open windows to improve ventilation while cleaning. 

Step 3: Clean Affected Areas 

For non-porous surfaces such as tiles and glass, use a mixture of detergent and warm water to scrub away mould. Avoid using bleach, as it does not eliminate mould roots and can cause harmful fumes. 

For porous materials such as carpets, fabric or drywall, removal may be necessary. Mould can penetrate deep into these materials, making it impossible to clean completely. 

Step 4: Dry the Area Thoroughly 

After cleaning, ensure the area is completely dry. Mould can return quickly if moisture remains. Use fans, dehumidifiers or increased airflow to speed up the drying process. 

When to Call in the Professionals 

While minor problems can often be handled with DIY methods, there are times when professional mould removal is necessary. If mould covers more than 10 square feet, is hidden behind walls or keeps returning despite your best efforts, expert intervention is needed.
