We specialize in inspection and testing

It is very important that our customers know that we do not perform any removal of mold, asbestos or any other contaminants. Ethically speaking, we believe it is not honest to act as an inspector and then be responsible for decontamination work.

This conflict of interest can sometimes leave you with sub par results and when it comes to your commercial or residential building, you deserve the best.

This is why you can trust QualiTAM's experts for your inspection and testing needs. We give you what you need at an affordable price.

The gentleman has inspected our property and we were very impressed with his professionalism. He guided us in the right direction and thanks to him we were able to make the right decision. I definitely recommend his services, as he has great knowledge and was very confident with his work.
