Phase 1 · Test

Know Your Number

Order a short-term test ($15–$30 charcoal canister from any Maine hardware store, lab fee usually included).
Run the test under closed-house conditions — windows shut for 12 hours before and during, 2–7 day duration. Place 20"+ off the floor in lowest livable level.
If on a private well, also test water radon through Maine HETL or your Cooperative Extension. Maine wells routinely test above 4,000 pCi/L.
Re-test in winter if your first test was in summer. Winter readings typically run 30–50% higher in Maine.

Phase 2 · Mitigate

Fix the Problem

If above 4 pCi/L, request 2–3 mitigation quotes from NRPP-certified Maine mitigators. Use our cost calculator for a sanity check.
Confirm the installer's credentials — NRPP certification (or NRSB), Maine business insurance, and references. See DIY vs Professional for what to ask.
Schedule installation — most homes are completed in a single day with the homeowner present.
Verify the install meets EPA/ASTM standards — fan in unconditioned space, discharge above roofline, working manometer, system labeled.

Phase 3 · Verify

Confirm It Worked

Run a post-mitigation test 24 hours – 30 days after install to confirm levels dropped below 4 pCi/L (target: under 2 pCi/L).
File your install paperwork — invoice, system warranty, manometer reading, post-test result. Important for resale.

Phase 4 · Maintain

Keep It That Way

Check the manometer monthly — a 30-second glance to confirm pressure differential is in the operating range. If it's level, the fan has failed.
Re-test every 2 years ($15 short-term test). Re-test sooner if you finish a basement, replace HVAC, or experience major foundation work. Plan for a fan replacement at year ~10–15 (~$300 with labor).

That's It.

Twelve steps, spread over a few weeks (or as long as you want). At the end, your home is radon-safe and you have the documentation to prove it — for your family today, and for whoever buys the house tomorrow.
