Sysco Environmental was commissioned to carry out a mould survey in relation to selected biological contaminants and to give recommended actions to take against existing mould contamination within the property. The objectives were to evaluate the presence of fungal contamination via visual inspection, evaluate and quantify the bioburden in the indoor air by means of non-viable sampling. Identify fungal species contaminating the indoor environment and the root cause of the indoor air pollutants and suggest appropriate control measures.
The property suffers from high humidity levels which are most likely associated with windows’ construction failure; however, it is strongly recommended to appoint a certified building inspector to evaluate the windows and also the suitability of the cavity wall insulation.
The moisture testing showed that the property is suffering from an extreme case of humidity and condensation, at the time of the inspection the internal humidity levels were exceeding 90% in all rooms. The windows were all affected by condensation both inside and between the glass panes. Water dripping was observed on top of the window frames and in some areas of the ceiling. Freestanding water was observed in the window construction and associated windowsills were saturated with moisture.
Several areas of mould contamination were detected mostly appearing around windows and external corner of the master bedroom.
Two minor leaks were detected, one to the plastic water storage tank in the loft, and one to the bottom of the drier in the kitchen.
The air within the property was damp and humid which results in poor air quality, the property was not heated and was relatively cold. The bathroom does not have a fitted extraction system. No significate sources of moisture were identified, and no significant leaks or service failures were observed.
Recommended actions to take
Firstly, we recommend removing any existing mould that has been identified via disposing of the contaminated materials and cleaning any affected construction materials this will significantly improve the air quality. Secondly, we recommend to extensively ventilate the property to remove residual mould spores from the air and to use dehumidifiers to reduce the indoor humidity levels.
You can carry out your own mould tests by using our Mould test kits which can be purchased here.
