Prokil were contacted by the owner of a property in Bournemouth to find out why mould was growing on the external walls of the lounge.
One of our trained Prokil specialists visited the property to investigate the cause of the problem. Upon arrival our surveyor saw large amounts of mould on the walls. Specialist instruments were used to ascertain the exact source of the problem. It was found that internal humidity levels were too high due to a lack of ventilation and poor heating management. Excess moisture in the air was condensing at the coldest part of the rooms; this condensed moisture then created the perfect environment for the mould to grow.
What we did
Our professionally qualified technicians installed a Passive Air Vent (PAV) into the lounge and a specially formulated surface biocide was used to treat the mould present on the walls. PAV’s are very effective at expelling excess airborne moisture by having a permanent opening in the wall through to the outside. They further benefit from having special filters within them to prevent cold air and excessive noise from entering the property.
