A note before you read. This article is general health and home-testing information for Greater Moncton homeowners and renters, drawn from publicly available Health Canada, NB Lung, the New Brunswick Department of Health, CARST, and Canadian Cancer Society materials.

Quick answer. New Brunswick has notable radon prevalence across many regions, including parts of southeastern NB. Health Canada and NB Lung have both flagged radon as a province-wide testing priority. Every Moncton home should be tested with a 3-month (≥91-day) long-term alpha-track test in the lowest lived-in level. If results exceed Health Canada's 200 Bq/m³ action level, mitigation by a C-NRPP-certified contractor typically costs $2,500–$4,500 for sub-slab depressurization. The New Brunswick Real Estate Association (NBREA) standard property condition disclosure generally engages with known material defects, including elevated radon.

Why Moncton Homes Need Testing
New Brunswick sits on a mix of Appalachian and Maritime geology that includes uranium-bearing parent material across many regions. The Moncton area, in southeastern NB, has shown elevated radon prevalence in NB Lung and Health Canada testing data.
Three factors:
- Geology. Appalachian and Maritime bedrock with uranium-bearing parent material distributed across many parts of NB.
- Long heating season. NB winters drive months of continuous furnace operation, producing strong stack-effect pressure differentials.
- Full-basement construction. Many Moncton homes have basements used as living space — exactly where radon concentrates.
NB Lung has historically run radon awareness programs and supported reduced-cost test kit promotions across the province.
What New Brunswick Data Shows
Health Canada's Cross-Canada Radon Survey reports New Brunswick with notable radon prevalence — in some surveys among the higher-prevalence Atlantic provinces. NB Lung's regional testing data shows that specific Moncton-area neighbourhoods can have elevated radon levels.
Practical implication for Moncton homeowners: test your specific home; provincial averages are not predictive of your specific reading.
How to Test Your Moncton Home
Health Canada's recommended test is a long-term (≥91-day) alpha-track test, deployed in the lowest lived-in level, ideally during the heating season (October–April).
For most Moncton homes:
- Finished basement if used as a bedroom, home office, gym, rec room, or rental suite
- Lowest sleeping level if the basement is unfinished
- Main floor only if the home has no basement
Place the kit at breathing height (1–2 metres), away from drafts, exterior walls, windows, and HVAC supply registers. Keep it in place for at least 91 days, then return to the lab.

Mitigation in Moncton
If your test exceeds 200 Bq/m³, the standard fix is active sub-slab depressurization (SSD). Typical Moncton-area cost: $2,500–$4,500 for a single-family home.
Always use a C-NRPP-certified Mitigation Professional. Verify on the C-NRPP Find a Professional directory, filter by New Brunswick.
For the full mitigator-selection playbook, see our How to Choose a Licensed Radon Mitigator in Canada guide. After mitigation, run an independent post-mitigation test.
Real Estate & NBREA Disclosure
The New Brunswick Real Estate Association (NBREA) Property Condition Disclosure Statement asks sellers about known material defects. NB common-law latent defect doctrine generally creates disclosure obligations for known material latent defects. A confirmed elevated radon test is generally the kind of information disclosure obligations may engage — consult a New Brunswick real estate lawyer for any specific transaction.

Renters in Moncton
New Brunswick's Residential Tenancies Tribunal administers NB residential tenancy law. NB law generally requires landlords to maintain rental units to a habitable standard. Moncton renters — especially in basement apartments — should consider testing. See our Radon for Canadian Renters (2026) guide.
Frequently Asked Questions
Is radon a real problem in Moncton? Yes — New Brunswick has notable radon prevalence and NB Lung has flagged the province as a testing priority. The only way to know your specific Moncton home's level is to test.
What's the action level for radon in Moncton? 200 Bq/m³ — the Health Canada residential guideline.
How do I test my Moncton home? Use a 3-month (≥91-day) long-term alpha-track test from a C-NRPP-recognized lab, placed in the lowest lived-in level during the heating season.
How much does radon mitigation cost in Moncton? Typical: $2,500–$4,500 for standard sub-slab depressurization (SSD). Get 2–3 written quotes from C-NRPP-certified NB contractors.
Can I use the Lungs Matter grant in Moncton? Yes — the Canadian Lung Association's Lungs Matter program offers up to $1,500 toward radon mitigation for eligible Canadian homeowners, including New Brunswick. Verify directly.
Does New Brunswick have provincial radon programs? NB Lung has historically supported provincial radon awareness and testing initiatives. Check directly with NB Lung for current offerings.
Do New Brunswick sellers have to disclose radon? The NBREA Property Condition Disclosure Statement and NB common-law latent defect doctrine generally create disclosure obligations for known material defects. A confirmed elevated radon test is generally the kind of information disclosure obligations may engage. Consult an NB real estate lawyer.
Should I retest after mitigation? Yes — Health Canada recommends retesting every 2 years after mitigation, or sooner after major renovations.
What if my Moncton landlord won't address elevated radon? Document everything in writing and consider escalating to the New Brunswick Residential Tenancies Tribunal.
Are there fewer mitigation contractors in Atlantic Canada? Atlantic Canada has fewer C-NRPP-certified contractors than central or western Canada. Plan ahead for scheduling, and check the C-NRPP directory for the closest qualified mitigator.
