Don't let radon kill your deal.
When radon comes up on inspection, you need answers fast — and a contractor your client can trust. RadonBase makes the radon part of any deal painless. Free referral program for agents.
Every contractor is verified
Each mitigator we list is checked against NRPP and NRSB databases — the two national radon certification bodies. No hiring uncertified contractors by mistake.

We email you when your referral submits a quote request. You stay in the loop — and can follow up with your client to keep the deal moving.
Why we built this
Radon issues kill deals. Buyers get a 4.5 pCi/L result, panic, and start Googling at midnight. They land on lead-auction sites that sell their contact info to 15 contractors who blow up their phone for a week. The buyer feels harassed, the deal stalls, and you spend hours managing it.
RadonBase exists to fix this. Every contractor is verified against the NRPP and NRSB certification databases. Your client's contact info goes to at most 3 mitigators near them — never auctioned to anyone with a credit card.
Free for you. Free for your clients. We make money from mitigators who pay for featured listings — not from selling buyer data.
Common questions
Do you pay commissions to agents?
No. There are no kickbacks, finder's fees, or commission splits. RadonBase exists to be a trusted resource for radon mitigation. We don't want to compromise that with referral incentives.
Will my clients get spam calls?
No. Each lead is routed to at most 3 verified mitigators in your client's area. We don't sell or share contact info beyond that. Most lead-auction sites sell each request to 5-15 contractors — we don't.
How do I know contractors are actually certified?
Every mitigator on RadonBase is verified against NRPP (National Radon Proficiency Program) and NRSB (National Radon Safety Board) databases. We don't list anyone who isn't in those records.
What does this cost?
Nothing. Agents and homeowners use RadonBase for free. We charge mitigators for featured listings ($49-149/month) — that's our entire business model.
Can I refer clients to a specific mitigator?
Yes. Every mitigator has a profile page you can link directly. Search by state, find someone you trust, and bookmark their URL.
Do I need to log in or manage anything?
Not for the referral link itself — just share it like any other URL. When a client of yours submits a quote request, we email you a confirmation. That's it.
