Mould is a type of microscopic fungus that thrives in damp, humid environments. It reproduces by releasing tiny, lightweight spores into the air. When these spores land on a wet surface with a food source like plaster, wood, or even dust, they begin to grow. The presence of mould in a property is always a definitive sign of an underlying moisture problem.

Next steps to take when you find mould
Dangers mould poses to your health and home
Mould is not just unsightly; it is considered a Category 1 health risk by the UK’s National Health Service (NHS). This is due to its potential to trigger or worsen a range of health issues, including allergies, asthma attacks, respiratory infections, and skin rashes, especially in vulnerable individuals like children and the elderly.
Beyond health risks, mould actively feeds on organic materials. Over time, it can lead to the decay and rot of timber frames, drywall, and plaster, silently compromising your home’s structure and leading to expensive long-term damage.
How to identify mould in your home
Look for these key signs that mould may be present in your property:
A Persistent Musty Smell: Mould often has a distinct, earthy odour even before you can see it.
Visible Growth: Look for discoloured spots or fuzzy patches of black, green, or brown on walls, ceilings, or fabric.
Peeling Paint or Wallpaper: As moisture builds up behind surfaces, it can cause paint to peel or wallpaper to bubble.
Damp Surfaces: Surfaces that feel soft or damp to the touch can indicate trapped moisture that is feeding mould.

Next steps to take when you find mould
if you’ve identified mould in your home, it’s crucial to act quickly and correctly. While it may be tempting to wipe it away, this only removes the symptom, not the underlying cause. Without addressing the moisture source, the mould will inevitably return.
To truly solve the problem, you need to find the root cause of the mould growth. This is where a professional damp survey becomes essential.
The importance of a damp survey
A professional damp survey is a comprehensive investigation into the source of the moisture. It goes far beyond what is visible on the surface. A qualified surveyor uses specialist equipment, such as moisture meters and thermal imaging cameras, to pinpoint hidden issues like:
Hidden leaks in pipes or roofs.
Rising damp, which occurs when moisture travels up through your walls from the ground.
Penetrating damp, caused by water leaking through a wall from the outside.
Condensation issues, often due to poor ventilation.
By identifying the exact cause of the moisture, a surveyor can provide a clear, actionable plan to fix it. This is the single most important step in preventing mould from returning. Without this crucial diagnosis, any cleaning or removal service is just a temporary solution, and you will likely find yourself dealing with the same problem again in the future.
Once the root cause is identified and fixed, a professional mould removal service can safely and effectively remove all traces of mould and decontaminate the area, ensuring your home is healthy and safe for good.
What is a mould removal service
A professional mould removal service goes beyond simple cleaning to provide a permanent solution. Experts use a multi-step process that includes:
Identifying the Source: Using specialist tools like thermal imaging cameras and moisture meters, professionals pinpoint the hidden source of moisture (e.g., a hidden leak or ventilation issue) that is causing the mould.
Safe Containment and Removal: The affected area is contained to prevent spores from spreading to other parts of your home. All mould and contaminated materials are safely removed.
Drying and Decontamination: The area is thoroughly dried and sanitised to ensure no mould spores or bacteria remain.
Final Restoration: The professional team provides a detailed plan to fix the root cause of the moisture, ensuring the mould does not return, and restores the property to a healthy, safe condition.
A professional mould removal service will help to successfully eliminate mould at the root and prevent re-growth. The cost of mould removal service varies depending on a number of factors. Check out another one of our blogs that looks at professional mould removal costs.

Remember, visible mould is a clear signal of a deeper issue. From DIY mould removal to professional mould cleaning services, the right approach is to always address the underlying moisture source. By acting swiftly and correctly, you can ensure a lasting solution that protects your family’s health and preserves your property’s value for the future.

Using specialised tools like thermal imaging cameras and moisture meters, a surveyor can pinpoint the hidden source of moisture (e.g., a leaky pipe or condensation problem), which is the key to providing a definitive, long-term solution.
How does a professional survey prevent mould from coming back?
A professional survey prevents recurrence by providing a detailed, actionable plan to fix the root cause of the moisture problem. By eliminating the conditions necessary for mould growth, the cycle is broken for good, protecting your health and home from future infestations.
