The Silent Threat

Radon is like smoking — except you don't know you're doing it.

Radon forms naturally in soil everywhere and seeps into your home through cracks in the foundation, gaps around pipes, and your sump pit. Once inside, it builds up. There's no smell. No taste. No warning sign.

🛠

Foundation cracks

Freeze-thaw winters and seasonal soil shifts crack concrete foundations every year, creating direct radon entry points.

💧

Sump pits & floor drains

Unsealed sump pits are a direct pathway for radon to enter your living space from the soil below.

🏠

Tight, energy-efficient homes

Modern well-sealed homes trap radon inside. Better insulation = higher radon buildup.

🥈

Without Testing

Unknown risk. Potential years of exposure. No ability to act.

🏠

After Testing

Know your risk. Take action. Protect your family with confidence.

Know Your Numbers

What do your radon readings mean?

Radon is measured globally in becquerels per cubic metre (Bq/m³). The WHO recommends action at 100, while many national agencies use 200 as a hard threshold. Here's what every level means and what to do next.

0–100 Bq/m³

Low Risk

Re-test in 5 years. Consider preventive sealing as a precaution.

100–200 Bq/m³

Moderate

Monitor continuously. Consider mitigation to reduce exposure.

200–600 Bq/m³

Action Level

Mitigation required within 1 year. Connect with a certified contractor.

600–800 Bq/m³

High Risk

Urgent mitigation required. Act within a few months.

800+ Bq/m³

Extreme Risk

Immediate action required. Contact a certified radon mitigation contractor today.

"Becoming a WellNest Insider was the best move we made this year. The Radon Guide arrived instantly, we ordered a test kit that week, and our basement came back at 340 Bq/m³ — way above the action level. The Insider portal connected us with a contractor and it's now fixed. Every homeowner needs this."

"I'm a first-time homeowner and had no idea radon was a thing. Since becoming an Insider, the Radon Guide explained everything in plain language — no scare tactics, just facts and a clear action plan. Tested at 85 Bq/m³, so we're in great shape, and the rest of the member library has been my home-ownership cheat code."

"My husband was skeptical at first. But our levels came back at 560 Bq/m³ and we're very glad we tested. The Insider portal contractor referral was seamless and the mitigation system was installed in one day. Sign up. Become an Insider. Just do it."

"We had no idea there were things a home inspector, doctor, or real estate agent should tell you — but don't. Becoming WellNest Insiders changed how we think about our home. The Radon Guide flagged levels 10x over the government action level. We're now on a path to a truly healthy home."
