Specialty · Radon Testing
Radon is common in New Brunswick, but it's easy to miss because you can't smell it. I set up a simple monitor to tell you if your levels are safe or if you need a fix. Confidence for your family's health.
The Hidden Danger
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.
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.
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.
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.
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.
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.

I'm certified through C-NRPP as both a Radon Measurement Professional and a C-NRPP Analytical Laboratory. That means your test is completed and analysed under the same national program Health Canada recognises and recommends when hiring radon professionals.
My certified in-house lab means you get results the same day I collect your device. No waiting weeks.
Airthings Pro and E-Perm devices provide accurate, reliable measurements you can trust.
Easy to understand reports with actionable next steps, not confusing technical jargon.
Dual certification as Measurement Professional and Analysis Laboratory.
I understand New Brunswick's unique radon landscape and building characteristics.
Licensed NBREA affiliate who works seamlessly with your transaction timeline.
How It Works
Call (506) 651-9461 or book online. I'll coordinate a time that works with your schedule and timeline.
I come to your home, set up professional-grade testing equipment, and explain the process. Takes about 15 minutes.
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.
I return to collect and seal the device, then analyse results in my certified lab and office.
You receive a detailed report with your radon levels and my recommendations the same day I collect the device.
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.
Within Health Canada's guideline. No action required. Consider retesting in 5 years or after major renovations.
Above guideline. Mitigation recommended within 2 years. I can connect you with certified C-NRPP mitigation professionals.
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.

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:
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 recognised 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.

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.

Common Questions
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.
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.
I work within your closing timeline and coordinate with realtors. Results give you negotiating power if levels are high, and peace of mind that your home is healthy if they're safe.
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.
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.
I'm C-NRPP certified with measurement and lab analysis, which means same-day results instead of waiting weeks. Plus, I'm an RHI-certified home inspector who understands both radon and homes.
