THE HIDDEN DANGER
Why Radon Testing Matters in New Brunswick
Radon is a radioactive gas that comes from natural uranium decay in soil. It's invisible, odourless, and the Leading cause of lung cancer in Canada.

Why New Brunswick Homes Are at Higher Risk
New Brunswick's geology is a significant factor. The province sits on rock formations that contain natural uranium, which breaks down into radon gas over time. This gas moves up through soil and enters homes through foundation cracks, gaps around pipes, sump pits, and floor drains.
Homes in Southern New Brunswick face additional risk factors:
Older foundations
Many homes in Saint John, Hampton, and Sussex were built with stone, block, or poured concrete foundations that develop cracks and gaps over time. These entry points allow radon to seep in more easily than in newer, sealed construction.
Basement living space
Finished basements are common throughout the region. A finished basement where your family spends time is the area most likely to have elevated radon levels and where exposure matters most.
Heating season
During New Brunswick's long winters, homes are sealed tight for months. Reduced ventilation allows radon to accumulate indoors. This is why Health Canada recommends testing during the heating season for the most accurate results.
No visible warning signs
Radon is colourless, odourless, and tasteless. A home with elevated radon looks and smells exactly the same as one with safe levels. The only way to know is to test.

HOW IT WORKS
Simple, Professional, Stress Free
1
Schedule Your Test
Call us at (506) 651-9461 or book online. We'll coordinate a time that works with your schedule and timeline.
2
I Deploy the Device
I come to your home, set up professional-grade testing equipment, and explain the process. Takes about 15 minutes.
3
Testing Period
The device measures radon levels continuously. Depending on your situation: 4 days minimum for home purchases, 7-30 days for current homeowners, or 31-91 days for best accuracy.
4
Collection & Analysis
I return to collect and seal the device, then analyze results in our certified lab and office.
5
Same-Day Results
You receive a detailed report with your radon levels and our recommendations the same day I collect the device.
Understanding Your Radon Results
Your report will include a clear radon level measured in Becquerels per cubic metre (Bq/m³), along with my recommendation based on Health Canada's guidelines.
Below 200 Bq/m³
Within Health Canada's guideline - No action required. Consider retesting in 5 years or after major renovations.
200-600 Bq/m³
Above guideline - Mitigation recommended within 2 years. I can connect you with certified C-NRPP mitigation professionals.
Above 600 Bq/m³
Significantly above guideline - Mitigation recommended within 1 year. Priority action advised.
If your levels are elevated, the fix is straightforward. A certified mitigation professional installs a sub-slab depressurization system that vents radon gas from beneath your foundation to the outside. Most residential mitigation systems cost about the same as a new hot water heater, and they reduce radon levels by up to 90% or more.
I do not perform mitigation work. This keeps my testing independent and free from any conflict of interest. If you need mitigation, I will connect you with certified C-NRPP mitigation professionals who serve Southern New Brunswick.
TESTING OPTIONS
Choose the Right Test for Your Situation
Radon Screening Assessment for Real Estate (4-7 Days)
Buying a home and need radon information before closing? The Radon Screening Assessment was developed by CARST (the Canadian Association of Radon Scientists and Technologists) specifically for real estate transactions where a long-term test is not practical within the sale timeline. The test runs for a minimum of 4 days under closed-house conditions and is performed by a C-NRPP certified measurement professional.
Results are reported using a colour-coded system developed by CARST:
Green Result: 75 Bq/m³ or less during heating season (50 Bq/m³ or less outside heating season). Lower likelihood that the annual average exceeds Health Canada's 200 Bq/m³ guideline. A long-term follow-up test is still required after you take possession.
Yellow Result: Greater than 75 Bq/m³ during heating season (greater than 50 Bq/m³ outside heating season) up to 400 Bq/m³. Higher likelihood that the annual average exceeds the guideline. Budget for potential mitigation costs during negotiations.
Red Result: Greater than 400 Bq/m³. Strong likelihood that the annual average exceeds the guideline. Mitigation costs should be factored into the purchase.
This assessment is an indicator, not a replacement for comprehensive testing. CARST and Health Canada both recommend that a long-term radon test be conducted once the new owners take possession of the home.
Short-Term Test (less than 90 days)
For homeowners who want results sooner than a full long-term test allows. CARST and C-NRPP define a short-term test as any radon measurement under 90 days. I deploy the device for a minimum of 7 days under closed-house conditions. A longer duration produces a more representative reading.
Important: A radon test shorter than 48 hours is never acceptable. Some non-certified companies offer 1-hour testing, and both CARST and C-NRPP are clear that this does not meet any recognized Canadian standard.
Short-term tests should always be followed up with a long-term test, as radon levels fluctuate with weather, wind, and barometric pressure. A short-term result provides a snapshot, not a complete picture of annual exposure.

Long-Term Test (91+ days) Health Canada Recommended
The most accurate way to understand your home's radon levels. Health Canada, CARST, and C-NRPP all recommend basing a decision to mitigate on a long-term radon measurement conducted during the heating season while the home is occupied. Testing during the heating season (October through April) captures the period when radon levels are typically highest because homes are sealed and indoor air is warmer than surrounding soil, which pulls more radon gas inside.
University of Calgary research cited by CARST found that 5-day tests predicted 90+ day results 80% of the time, but accuracy dropped significantly in summer months. This is why the long-term test during heating season remains the gold standard for making a mitigation decision.

All tests use professional grade C-NRPP approved devices. I will recommend the right test for your situation when you book.
COMMON QUESTIONS
Frequently Asked Questions
Where Should I Test My Home?
Test in the lowest livable level (usually the basement) at least 2 feet above the floor. Close all windows and exterior doors 12 hours before and during testing.
Can radon problems be fixed?
Yes! Even very high levels can be reduced to acceptable levels. Most homes can be fixed for about the same cost as other common repairs (like a new hot water heater). I connect you with certified C-NRPP mitigation professionals.
What if I'm buying a home?
I work within your closing timeline and coordinate with realtors. Results give you negotiating power if levels are high, and knowledge that you and your home is healthy if they're safe.
What is an acceptable radon level?
Health Canada's guideline is 200 Bq/m³. Levels above this require action within 1-2 years depending on severity. The good news: even very high levels can be reduced to safe ranges.
Is radon only a problem in certain areas?
High radon levels have been found in every province. New Brunswick has particularly high rates, but the only way to know YOUR level is to test YOUR home.
Why choose East Coast Home Inspection for radon testing?
