We offer microbiological and indoor air quality assessment services, inspections and general consulting as this relates to microbiological contamination generally following water damage and mould for which we specialize. As a general guide, our fees are as follows :

1. Inspections include a visual walkthrough of all habitable areas.  Testing is normally for all habitable rooms.  This is to provide a comprehensive report that accurately assesses the indoor air quality and any impact from visible or hidden mould on your airspace, and hence respiratory health.  Testing will always include a combination of airspace and surface sampling.  There are no hidden charges or per sample fees and we do not outsource any testing to other labs.  Standard pricing for a 2-bed home or apartment is from $2000+gst, and for a 3-bed home/apartment is $2500+gst, etc.  Any inspections where there is an expectation of civil litigation should anticipate a base fee of $2500+gst per inspection or higher depending on property/building size. Frame inspections start from $2000 + gst for a single story and a 2-story Frame inspection from $2500 +gst.


2. Specific testing of individual samples or sampling provided by other occupational hygienists, remediators or consultants could require specific microbiological culture and analysis. A guide to our fees is a as follows: viable petri plate sampling (air or surfaces) and typing to Genus and Species where possible: $100 + GST each (PDA, MEA, SDA, NA, CHROM, HB, etc. using our plates, or $89 if using yours).

Testing for mould indoors follows the description at Point #1 where comprehensive indoor air quality inspection prices are fixed according to the general size of the home as measured by the number of bedrooms, e.g. 2, 3, 4, 5+ bedroom homes/apartments/residential and commercial properties.

In general, inspections will only assess the habitability of the airspace within the room volume/s and selected surfaces that may be suspected to be mould or water damaged. Companion assessments within walls, ceilings or at subfloor level is normally a separate set of tests and are distinguishable as 'habitable room risk' versus 'structural component risks'. Additional costs will depend on the number of samples and what the objective of the assessment is trying to address. Call for an estimate on price: 1300 13 23 50 or email: [email protected]

This is normally relevant only for directions hearings. In the event that hearing or tribunal schedules are anticipated to run over multiple days, then the client will be charged the full day fee regardless of actual appearance times. This is due to being reasonably absent from professional places of business/lost work for other projects and the requirement that calendar schedules are blocked off for hearing attendance often some time in advance. If I as an expert have blocked off time for attendance/s and the matter is adjourned and/or mediated/settled or if attendance is no longer required prior to 14-days, then the full anticipated rate will be levied to the client for payment. Payment is required in full prior to attendance and/or secured by a written authority with your solicitors' trust account. Zoom appearances will also be charged as per the above terms.  Where cross-examination does not occur for whatever reason, but time has been scheduled for appearance, then the full fee is payable.  Pre-hearing discussion/s with Counsel or other persons along with time for the review of reports and printing or reading of any other documents or emails will attract extra time-based fees.
