Mould is all to do with moisture. Every household has mould spores present and these mould spores can generate into visible muld growth if moisturer and a food source is in attendance. So the testing for mould obviously involves the identification of hidden moisture.

It is important to note that all dwellings have some form of mould unless it is a sterile environment. Mould spores can be found in dust. However it will not grow unless exposed to moisture so it is important to keep the dwelling free of excess moisture and to properly vent moist areas. If moisture does penetrate the dwelling it is vital that it is removed as quickly as possible.

Mould reproduces itself through tiny invisible spores, which resides and travel through dust.

Mould is potentially harmful to humans, affecting the respiratory functions and manifests itself in hay fever type symptoms and those with allergies can suffer an allergic reaction to mould.

Prolonged exposure to mould can cause severe illness and even death in very extreme cases.

There are two distinct types of mould in any dwelling and identifying both is critical to any successful mould identification and remediation program.


VISIBLE MOULD - Visible mould is identified via visual inspection and/or surface swabs to determine the type of mould colony present, visible or not.

MOULD SPORES - Mould spores are invisible airborne particles and our purpose specific equipment can test for the amount of airborne particles in the indoor atmosphere. All buildings have some airborne mould spores/particles, and our job is to ensure that they are below the acceptable level. Our before and after testing ensures the buildings' compliance with these figures.



Mould needs to be both identified, treated and prevented. There is little point in removing the mould if the reason for the mould growth - moisture, humidity, lack of ventilation - is not repaired or reversed.

1. Identification

Our mould identification equipment is the most advanced in the industry so you can be assured we will identify any worrying issues with regard to mould in the built environment, whether it is invisible mould (spores) or visible mould. Vidsible mould is located and identified by following the moisture trail using either infra red cameras or moisture metres.

2. Measurement

Our aerosol monitors can test the amount of airborne particle sin the indoor atmosphere and determine if they are in excess of the permissable particulate count as per recognised environmental standards. (0.55mg/m3). Surface swabs determine the existence of otherwise invisible surface mould colonies.

3. Sample

If it is determined by our testing that the particulate count is elevated, we can trap and sample airborne particulates or take surface swabs and forward them for testing. Visible mould can also be sampled via swabs or physical capture of visible mould and then forwarded for testing to an authorised laboratory.

4. Laboratory testing

We can have airborne particulates and surface swabs tested and these laboratory tests can determine what type of mould has generated in the dwelling. Lab testing is an optional extra as the vaklue of determining the type of particulate or the type of mould is questionable. Often the presence of elevated particulate levels is enough to undertake remedial action without paying to determine the exact type of particulate.


Visible mould is remediated or removed from the indoor atmosphere by hand cleaning of the affected areas. With badly contaminated porous surfaces (plaster, wood etc), replacement may be required if cleaning is deemed unsuccessful. Invisible mould (mould spores) is removed using airscrubbers which scrub and cleanse the indoor air.
