About Radon Repair
Maritime radon experts since 2016
We educate, test, mitigate, maintain and monitor for radon, in an environment of integrity, trust and respect with our clients, employees, suppliers and community.
Our story
Built on building science
Jeff LeBlanc founded Radon Repair in 2016. Today he runs it with Doug MacDonald, General Manager and part owner. Both are Certified Master Inspectors, with 8,500+ home inspections behind them.
That background is why we spend the time on diagnostics, set honest expectations, and keep working on the more complex homes until they're right. 1,000+ mitigations later, that hasn't changed.
Why we do this
Angela's Promise
Angela, of Havelock, NB, called us after a Stage 4 lung cancer diagnosis. Her home tested well above 10,000 Bq/m³, with spikes to 20,000, the highest levels we'd ever found.
We mitigated her home and protected her loved ones. It couldn't change her diagnosis. Angela's wish was to create more awareness, so more people would test and mitigate their homes.
We say her name every day. Angela's Promise, our in-home radon education and testing service, exists because of her.
