Where the cause of the mould is related to building faults (such as a leak) and/or the mould is present in the building structure and materials it is recommended that you seek professional help.

Whether the job is undertaken by a contractor or yourself, care has to be taken to avoid contact with microscopic mould spores and the spread of spores within the building.

In cleaning away mould:

• Wear rubber gloves, goggles without ventilation/air holes and a protective mask which covers your nose and mouth.
• Open windows before, during and after the clean up but close doors tightly to prevent mould spores transferring to other areas of the building.
• To get rid of mould you can use a vacuum cleaner and empty it afterwards or use a damp cloth that you throw away afterwards. Do not brush the mould as it releases spores into the air that may make cause you breathing problems. 
• Next wipe down affected areas using a mild detergent such as washing up liquid, diluted bleach or a fungicidal wash (always follow the safety instructions on the bottle). 
• You can also try using tea tree oil, which is a natural antiseptic and disinfectant. Mix three to four drops of tea tree oil with two litres of hot or cold water, spray it onto bad spots and then wipe/rinse it off.  Make sure to do a test on a small bit of the fabric/surface beforehand to avoid discoloration.
• Allow the surface to dry and hoover the room to remove mould spores disturbed and transferred during removal before redecorating using a fungicidal paint or wallpaper paste.
