Emergency response is typically needed for Asbestos and PCB testing. 

Onsite Mould Identification may also be rapidly required for health safety or insurance purposes (e.g. after a flood).

For independent environmental analysis, our laboratory pricing is always provided via quotation. Whether you are an engineer, a builder, insurance company or a home owner, we have a “cost per project” model and we do our best to help you with your budget. We also offer bulk pricing for larger and more involved projects. 


Call ( 905-475-7755 x227) or email us for exact pricing. We can also email you a guideline fee schedule for your quotations needs.


When is Testing Needed?

Testing is often necessary when renovating, demolishing, or for regulatory procedures during site development planning.

Analysis is also needed to identify possible contamination that may have leached from a neighbouring property.

For the home owner or property manager, testing is typically required when mould accumulates after a flood or if older building materials (such as asbestos) are uncovered.
