What is professional mould removal?

Professional mould removal is the process of identifying, treating and removing mould from a building in a safe and effective manner. It involves a combination of physical cleaning and chemical treatment to ensure that all mould is properly treated, reducing the risk to health. That's where professional mould removal steps in.

How does Pure Maintenance carry out professional mould removal?

When Pure Maintenance UK receives a call from a customer, they are first taken through a process of registration and information gathering with one of their customer consultants. Once all of this is done, a time and date are agreed upon for the technician to visit the property.

The first part of the Pure Maintenance treatment is the application of InstaPURE, a patented EPA-registered sterilant. InstaPURE works by denaturing mould and other microorganisms; stripping them of their functional properties and rendering them inert. InstaPURE is delivered via our patented dry fog technology. The dry fogger condenses InstaPURE to such a small particle size that it is unable to condense on surfaces, meaning the fog can remain suspended in the air. This is significant as 95% of mould is invisible and can be airborne, on surfaces, embedded in soft furnishings and clothing or hidden behind walls and under floors. Once all mould contamination has been treated, we begin the next step in mould removal.

The fog is delivered via positive air pressure, meaning the fog is forced into every conceivable space in the property. All mould strains are destroyed by the sterilant (even the dreaded black mould) due to the systemic nature of our treatment - surface mould, airborne mould spores, hidden mould within walls and under floors and in soft furnishings are all treated by InstaPURE. Once all of the mould in your home has been treated, your technician will physically wipe away the inert mould and any other visible affected areas.

The second part of the Pure Maintenance treatment is the application of our anti-microbial film, EverPURE. EverPURE is applied to all surfaces in the home. It forms a covalent bond with the surface, meaning it is permanently bonded to the surface and cannot be removed by cleaning. The anti-microbial film is made up of positively charged nitrogen molecules with carbon atoms stacked on top. Microscopically, it looks like a bed of nails as the carbon atoms create a spike. Any new pathogens introduced to the property following our treatment are electrostatically attracted to the positive charge and the carbon spike pierces the outer membrane, denaturing the microbe. We apply an antimicrobial film to all surfaces to help inhibit regrowth. When mould remediation is carried out properly, it can be a highly effective way to address mould problems and provide long-lasting protection against future mould growth.

Your technician will then take a post-treatment air test in the treated area, confirming that mould levels are at or below outdoor levels. This is a long time indeed, ensuring improved air quality and mould load reduction across treated surfaces. InstaPURE and EverPURE are applied in accordance with COSHH and HSE requirements.

What warranty does Pure Maintenance offer?

Following treatment, your technician will offer you a 1-year warranty. If the mould comes back, so do we - for free. This is because we are so confident in the quality and thoroughness of our treatment.
