Hiring a radon mitigation contractor shouldn't feel like a gamble.
when buying a home, after an elevated radon test result, or when building on radon-prone land, you need a provider who shows up on time, knows their craft, and won't drop the ball on the details. But you're stuck cold-calling strangers from a Google search.
What's at stake when you hire the wrong one?
Substandard work
Missed details, incomplete deliverables, or unqualified staff. You won't know until it's too late.
Wasted budget
Rework, remobilization, and re-scheduling. Typical lost cost: $800-$1,500 per mitigation install ($150-400 for testing only).
Downstream risk
Failed audits, delayed projects, or compliance exposure. One bad hire can cost you the whole engagement.

The team
Nick Palmer
Founder & Lead Researcher
Nick built RadonTrust because the radon industry still mixes measurement and mitigation in ways that create conflict of interest — the same pro who tells you your level is high often wants to sell you the fix. This directory surfaces independent, credentialed professionals first.
