…What We Do…


Radon is a radioactive gas that is formed as a result of breakdown of uranium in soil, rock and water. Radon has been known to be the leading cause of lung cancer in Canada in which about 3000 people die annually. Radon can enter homes through windows, cracks in foundations. We can conduct short term and long term testing for radon and help to mitigate it.

Industrial Hygiene

Industrial hygiene is the art of anticipating, recognizing evaluating and controlling chemical, biological, physical and environmental hazards in the workplace. Tadex Environmental  can help to perform air quality sampling in welding and mechanic shops, diesel fumes, noise assessment and particulates.

What our clients say

We were experiencing coughing, sneezing and flu-like conditions in our home. We have had over 3 different consultants from different companies come by to do air quality tests but still no changes. When we called Tadex, the gentleman we spoke with was very thorough. He asked us a lot of questions and finally came by our home for further assessments. After the several inspections and walk through assessments as well as testing, they gave us recommendation to resolve the underlying issue. I can say since we called them, my family has been feeling much better. I highly recommend them.

I highly recommend TADEX

We had mold in our home, after we hired a contractor to remove the mold, Tadex did a post remediation air quality sampling for us to ensure no spores are present in the air and to validate the contractors work. The staff at Tadex were knowledgeable.

TADEX Staff are competent

Almost a year after  the fort mcmurray fire, I was suffering from cold, cough etc, I called Tadex Environmental and the consultant I spoke with came by for an assessment. I am now doing great with no cold anymore.

TADEX is the best
