Pricing starts at $255.00 which breaks down to the following: Mould Testing is taking actual samples of the mould from a surface to determine the type of mould(s). First sample is $155, plus subsequent samples are $100 each, or one mould sample combined with air samples would only be an extra $100. Air Quality testing, which will supply information regarding type and quantity of mould spores in the air, requires a minimum of two samples; one outside and one inside (depending on the areas of concern there can be more samples needed inside). The first three samples are $330.00 plus each additional air sample is $100. I would need to discuss with you the appropriate tests needed.Testing for asbestos in building materials, if there is a concern, costs $100 per sample.
