OUR EDITORIAL RULE

Real provider data, not affiliate fluff.

RadonTrust is a directory of NRPP-credentialed radon mitigation contractors. When we publish pricing or vetting data, it comes from the same provider records that power our search index — not stock industry reports or AI-generated copy.

We don't take affiliate commissions. We don't gate the PDFs. The guides exist because homeowners told us the most-Googled questions had no straight answers online. So we wrote them.

Quick answers

Before you download.

Do I have to give my email to download?

No. Click any cover or the green Download button and the PDF starts immediately. We'll offer a newsletter subscription afterward, but it's completely optional.

Are these actually free, or is there a catch?

They're actually free. RadonTrust makes money from radon mitigation contractors who advertise their listings — never from selling your information. Every guide is also published as a web article you can read without downloading anything.

How often do you update these?

Pricing data is refreshed annually as radon mitigation contractors update their rates. Methodology and credential references are reviewed quarterly and revised whenever the underlying standards change.

Can I share these with colleagues?

Yes. Share the URL or attach the PDF — we just ask that you keep the cover and credit page intact. Bulk distribution? Reach out via the contact link in the footer and we'll set up a co-branded version.
