Our consultants have conducted detailed site investigations and inspections to resolve numerous issues regarding indoor air quality throughout the UK. Our services usually start by doing visual inspections of the premises or areas to be surveyed.  If permitted, we will also question individuals expressing complaints to further identify their symptoms and the frequency of on-set. The usual items to be reviewed will include:

• Observation of potential sources of airborne chemical contamination (e.g. engines, chemical processes, neighboring facilities, construction etc).

• Inspection of layout and distribution of air supplies to the occupied spaces.

• inspection of the condition of the HVAC systems and accessible components, such as filters, condensate drip trays, heating and cooling coils, air intakes, air supply and return grilles and accessible duct work etc.

• Observation for evidence of water ingress, excessive moisture or microbial growth.

• Contamination sources near HVAC and air intakes and returns.

Our basic indoor air quality survey covers:

Temperature, relative humidity, carbon monoxide, carbon dioxide, nitrogen dioxide, sulphur dioxide, hydrogen sulphide, formaldehyde, airborne bacteria, fungi, yeast and moulds, airborne particles and air movement tests. Results should be measured against current standards, regulations and guidelines.

However, if needed we can go that step further and conduct very specific VOC analysis, gas analysis and duct work deposit thickness testing etc as required.
