What is Mould?
Mould is a naturally occurring type of fungus that develops in environments where excess moisture, organic material, and limited airflow are present. It plays a vital role in nature by decomposing dead plant matter, but when mould begins to grow indoors on walls, ceilings, furniture, and floors it becomes a persistent and potentially hazardous problem.
Mould reproduces by releasing microscopic spores into the air. These spores are invisible to the naked eye and are almost always present in the environment, both indoors and outdoors. When they land on a damp surface inside your home or building, they can begin to grow and spread rapidly. Within 24 to 48 hours of exposure to moisture, certain mould types can start to take hold making early detection and control essential.
Indoors, mould is commonly identified by dark patches that can appear black, green, brown, white, or even pink depending on the type. These patches often develop in corners, behind furniture, around windows, on ceilings, in bathrooms, kitchens, and other poorly ventilated areas. In addition to its appearance, mould often gives off a strong, earthy or musty odour a warning sign that shouldn’t be ignored.

Steps for a Mould-Free Home
Mould isn’t just unsightly it’s a sign that something deeper is going wrong in your property. Left untreated, it can damage walls, trigger health issues, and keep coming back no matter how often you clean it. At Total Damp Repair LTD, we follow a structured, professional approach that goes beyond surface-level removal to deliver lasting results. Here’s how we help you achieve a safe, clean, and mould-free home in just three clear steps:

Every successful mould treatment starts with understanding the cause. We begin by inspecting your property to locate both visible and hidden mould, and identifying the underlying issues whether it’s poor ventilation, excess humidity, rising damp, or a hidden leak. This step ensures we’re not just treating the surface, but solving the problem at its source.

Once we know what’s causing the mould, we carry out a safe, thorough cleaning process using professional-grade biocidal solutions that kill mould spores and disinfect contaminated areas. We remove all visible growth while ensuring airborne spores are contained, leaving the space clean, safe, and free from harmful fungal residue.

The final step is making sure the mould doesn’t come back. We offer tailored advice and practical solutions from improving airflow and ventilation to recommending PIV units or extractor upgrades. By managing moisture and controlling humidity, we help you maintain a healthier, mould-free environment for the long term.
How We Clean and Treat Mould
At Total Damp Repair LTD, our approach to cleaning and treating mould goes far beyond a surface wipe. We follow a structured, professional process designed to not only remove visible mould, but also eliminate the conditions that allow it to grow in the first place.
1. Investigation & Diagnosis
Before any cleaning takes place, we carry out a detailed mould and damp investigation using moisture meters, thermal imaging, and visual assessment. We identify where the mould is forming, how far it has spread, and most importantly why it’s appearing. Whether it’s rising damp, condensation, a hidden leak, or poor ventilation, we find the source.
2. Safe Removal of Mould
We begin the cleaning phase by safely removing visible mould from walls, ceilings, skirting boards, windowsills, or other affected surfaces. We use professional-grade biocidal and antifungal solutions, not just bleach, to break down fungal growth and kill the spores embedded within the surface. All areas are cleaned with care to avoid spreading spores to unaffected areas.
3. Air Purification & Spore Control
In spaces with heavy mould presence, we may use air filtration units to remove airborne spores during and after treatment. This step helps reduce the risk of regrowth and improves the air quality in your home or workspace.
4. Drying & Dehumidification
Moisture is mould’s biggest enabler. Once cleaning is complete, we make sure the area is properly dried and dehumidified using professional drying equipment where needed. This helps to create an environment where mould cannot return.
5. Addressing the Root Cause
The most important part of our treatment process is prevention. We’ll explain what caused the mould in the first place and provide tailored recommendations whether it’s improving ventilation, installing a PIV unit, applying damp-proofing treatment, or repairing leaks.
6. Final Report & Aftercare
After the treatment, we’ll walk you through the work carried out and provide aftercare advice to help keep your property dry and mould-free long-term. Our goal is not just to remove mould, but to prevent it from ever coming back.
Why Protect your Property from Mould?
Protect Your Health
Mould releases spores that can trigger respiratory problems, allergies, asthma, and skin irritation especially dangerous for children, the elderly, and those with existing conditions.
Prevent Structural Damage
Left untreated, mould can weaken walls, ceilings, and floors by feeding on organic materials like wood and plaster, leading to costly repairs.
Avoid Decreased Property Value
Visible mould and damp issues can make your property harder to sell or rent, significantly affecting its market value and appeal to potential buyers or tenants.
Stop It from Spreading
Mould spreads fast if ignored. Treating it early reduces the risk of it invading other areas of your home or commercial building.
