FAQ: Radon Mitigation in Massachusetts

Is radon a problem in Boston?

Greater Boston is Zone 2 — moderate risk. But plenty of homes in the metro test above 4.0. Always test regardless of zone.

How much does radon mitigation cost in Massachusetts?

Most homeowners in Massachusetts see mitigation quotes in the low-thousands, but the final cost depends on foundation type, fan location, and pipe routing complexity. A cost calculator can help you benchmark estimates before requesting bids.

Do I need radon testing in Massachusetts before hiring a contractor?

Yes. A valid short-term or long-term test is the fastest way to confirm if mitigation is needed and to scope the right system design.

What radon level is dangerous in Massachusetts?

EPA recommends action at 4.0 pCi/L, and many homeowners choose to reduce levels even below that threshold. Western and central Massachusetts have significant Zone 1 areas. The eastern part including Greater Boston is mostly Zone 2. ZIP-level lookup tools are useful for local context, but home testing is still required.

How do I choose a certified radon contractor in Massachusetts?

Look for current NRPP or NRSB credentials, ask for post-mitigation test expectations, and confirm local compliance details. Massachusetts does not require state-specific radon licensing, but NRPP/NRSB certification is recommended for all professionals.
