Mould Remediation

Professional Mould Remediation in Clapham

Mould is one of the most common — and most dangerous — consequences of water damage in properties across South London. Whether you’re dealing with visible black mould on walls and ceilings or suspect hidden mould growth behind plasterboard, our certified mould remediation service in Clapham safely eliminates all mould contamination and prevents regrowth.

Mould spores can cause serious respiratory problems, allergic reactions, and chronic health conditions, particularly in children, elderly residents, and those with existing health issues. Our PCA-certified mould remediation technicians follow strict containment and removal protocols to ensure complete, safe elimination of all mould contamination from your property.

Our Mould Remediation Process

• Mould assessment & testing — We conduct a thorough inspection to identify all mould-affected areas, including hidden mould behind walls and within cavities. Air quality testing confirms the type and concentration of mould spores present.
• Containment — Affected areas are sealed with negative air pressure containment to prevent mould spores from spreading to unaffected parts of your property during removal.
• Safe mould removal — Using HEPA-filtered equipment and certified antifungal treatments, we remove all visible mould growth from affected surfaces, timber, and building materials.
• Antimicrobial treatment — All remediated surfaces are treated with professional-grade antimicrobial solutions that kill remaining spores and create a protective barrier against future mould growth.
• Source elimination — We identify and address the underlying moisture source causing the mould, whether it’s a hidden leak, condensation issue, or inadequate ventilation.
• Clearance testing — Post-remediation air quality testing confirms mould spore levels have returned to safe, normal levels before sign-off.

Types of Mould We Treat

• Black mould (Stachybotrys chartarum) — The most dangerous variety, often found in persistently damp areas. Produces toxic mycotoxins that cause serious health problems.
• Aspergillus — Common household mould that triggers allergic reactions and respiratory infections, especially in immunocompromised individuals.
• Cladosporium — Often found on fabrics, carpets, and wood surfaces. Causes allergic reactions and can exacerbate asthma symptoms.
• Penicillium — Rapidly spreading mould that thrives on water-damaged building materials. Can cause allergic reactions and respiratory problems.
