Scale Mould Remediation Ensures Full Compliance for Facilities Management Company

In December 2024, a black mould infestation spread to affect over 100 rooms in the staff quarters of a public sector building. This posed a severe risk of allergic reactions, respiratory illness and fungal infections to occupants.

Under the Health and Safety at Work Act 1974, the building’s facilities management company was legally required to keep the premises and its occupants safe from hazardous mould spores. A rapid response was essential, but the mould was discovered just before the Christmas break, so the timing presented a major challenge.

Full remedial works were not an option due to cost, and in-house cleaning would have been hindered by limited availability over the festive period. To overcome these challenges, the customer turned to Rentokil Specialist Hygiene’s 24/7/365 emergency response team of wholly-employed technicians.

Our customer required a full remediation within a strict two-week deadline. Our RSPH-accredited technicians were already security-vetted, so we immediately mobilised six technicians per day.

To ensure the best results in this limited timeframe, our expert technicians implemented a structured cleaning and disinfection regime starting with our innovative two-part mould remediation process. In step one, all surfaces were methodically cleaned with an industrial-grade Mould Eliminator solution. Then the team applied Mould Clear Ultimate to create a protective barrier that kills any existing mould residue and hinders regrowth.

Throughout the treatment, AIRTrinity air purification units with built-in HEPA filters provided clean, purified air to each room, removing harmful airborne spores. This protected our team while they worked and reduced the risk of the mould returning.

After thorough cleaning, the living quarters were disinfected to remove any lingering pathogens and mould roots embedded in porous wallpaper and plasterboard. For full sanitisation, our experts opted for electrostatic fogging. This innovative treatment electrically attracts disinfectant droplets into hard-to-reach areas, making it perfect for lodgings with beds, wardrobes and heavy furniture.

Despite the scale of the affected areas, and the tight project deadline, Rentokil Specialist Hygiene expertly remediated all 100 rooms within the allotted two weeks.

Our efficient response minimised health and safety risks and enabled the occupants to move back in swiftly. Our thorough remediation also ensured the facilities management company remained fully compliant with the Health and Safety at Work Act 1974.

As a testament to our reliability, speed of response and “excellent service” during this project, our customer continues to trust Rentokil Specialist Hygiene as their expert partner for all mould removal projects.
