C-NRPP Certified Radon Companies in Ottawa
Every company holding current Canadian National Radon Proficiency Program certification that is based in Ottawa, or that names Ottawa in its own service area. Listed free, whether or not they know this page exists.
Two lists, because the difference is a fact and the alternative is a guess. The first is companies whose registered address is here. The second is companies based elsewhere in Ontario that state they cover this area. We do not assume that a firm in one town serves the next one over, so if you do not see enough names, the
full Ontario list has everyone.

What the Two Certifications Mean
C-NRPP certifies separately for measurement, finding out what a home reads, and for mitigation, installing the system that fixes it. Plenty of companies hold only one. If a test has come back high, you want a company on the first list above.
