How we review contractors
We introduce homeowners to independent mitigation contractors and are paid by those contractors for the introduction. That makes our intake standard the thing worth publishing — it is the part a homeowner is relying on without being able to see it.
This page describes what we actually check. It also describes, at equal length, what we do not, because a review process oversold is worse than one honestly bounded.
What we verify before routing anything
Credential, with the issuing authority rather than from the contractor’s own materials. In states that license or certify radon work — Illinois, Iowa, Nebraska, Minnesota, Ohio, Pennsylvania, and Kentucky — that means the state credential, confirmed current and confirmed to cover mitigation rather than measurement alone. In states that do not license radon work — Wisconsin, Michigan, and Colorado — it means current NRPP or NRSB certification, confirmed with the programme.
Insurance, as documentation rather than assertion. Service area, so that requests route to businesses that actually cover the address. And a written scope of work, because a contractor who cannot produce a sample scope naming suction points, routing, fan model, sealing, warranty terms, and a post-mitigation verification test is not the kind of business we want introducing homeowners to.
- State licence or certification, verified with the issuing agency, current, covering mitigation
- NRPP or NRSB certification where the state does not license, verified with the programme
- Proof of insurance
- Declared service area matched against our routing territories
- A sample written scope of work
What we re-check, and when
Credential currency is re-checked on our own schedule rather than only at intake, because a licence verified once is a fact about that day. A credential that has lapsed stops routing.
We also act on homeowner reports. If a homeowner tells us a contractor misrepresented a credential, failed to provide the written scope, or would not perform verification testing, that is grounds for removal — and it is the most useful signal we get, because it comes from the transaction itself.
What we do not do
We do not inspect installations. We do not warrant anyone’s work — the contractor designs, installs, and warrants the system, and your contract is with them.
We do not rank contractors by quality, because we have no defensible basis for a ranking and any scoring we invented would be marketing dressed as assessment. We do not publish reviews or ratings for the same reason.
We do not guarantee that a contractor will be available for your address or your timeline. Coverage varies and schedules fill; we tell you honestly when we cannot cover a ZIP rather than routing a request nowhere.
And we do not check a specific contractor for you on demand as a service. The verification that protects you is the one you perform before signing.
Why you should verify anyway
Our check happens at intake and on our re-check schedule. Yours happens on the day you are about to sign a contract, which is the moment that matters.
It takes a phone call. Ask for the credential number as it appears on the contract, then confirm it with the agency named on your state’s resource centre — or with NRPP or NRSB in a state that does not license. If the number does not check out, nothing else about the bid matters.
How we are paid, stated plainly
Contractors pay per referral. There is no application fee, no monthly platform charge, and no purchased exclusivity — a contractor cannot buy better placement or a bigger territory from us.
Homeowners pay nothing and are under no obligation. That arrangement is disclosed on every page of this site, not only here.
