How we Treat Mould
The first step with mould remediation as with water damage restoration will always be to stop the source of the moisture that is encouraging the spread of the mould. There are various ways to do this and some of the treatment may include replacement of impacted areas, but this will normally be completed at the assessment stage.
By attending to these areas quickly and fixing these problems will help to prevent the further spread of mould and will make it possible to treat the mould in the worst affected areas. This is very important as mould can grow on porous surfaces in as little as 24 hours.
The area will then be dried which must be done carefully so as to prevent the spreading of dust and mould spores. Where the mould has set in under carpets, within the walls or in insulation, this might involve the removal of fittings and fixtures.
The next stages in treatment will often depend on the severity of the mould and the extent of the damage within your home or business. For small amounts of mould it will sometimes be safe to use simple surface cleaning with a sponge or a cloth and a cleaning product. In the past some methods of mould remediation have involved the use of fungicides and hot air, though these have been deemed unsafe for the atmosphere.
In more severe mould infestations, Flood Restoration Australia will ensure that strict guidelines from the IICRC S520 on procedures to remove mould will be undertaken.
These are ‘high-efficiency particular air’ vacuums which are often used at the end of the mould remediation process. These can remove dust and mould spores from the affected surfaces. Re-mediators will wear PPE (personal protective equipment) to prevent themselves from being exposed to the captured mould and it will then be disposed of using tightly sealed bags.
Dry Ice Blasting
This method is used by some companies as the initial source removal stage generally from wooden surfaces and other materials such as cement. Soda blasting and media blasting can also be used. In other cases, some items may need to be permanently discarded. These include all kinds of porous materials including pillows, mattresses, plaster board walls and underlay. Mould specialists will often handle this disposal on your behalf. Cleaning may also be necessary for your heating and air conditioning systems in order to prevent the further spread of mould spores throughout your building.
Some mould remediation companies will also provide additional clean-up and restoration services in order to help you get back to normal. These include such services as fabric restoration, painting, carpet installation etc. These companies ensure that you are able to return to your home and normal standard of living as soon as possible and they can be a huge benefit to families and business struggling with mould issues.
Ultraviolet germicidal irradiation (UVGI)
Ultraviolet germicidal irradiation (UVGI) is a sterilization method that uses ultraviolet (UV) light to kill airborne micro-organisms. Bacteria, viruses and micro-organisms (like mould spores) have less protection from UV and cannot survive prolonged exposure to it.
