Preparation is simple but crucial: Maintain closed-building conditions for at least 12 hours before our technician's arrival and throughout the test. Keep all exterior windows and doors shut (except for rapid, normal residential entering and exiting). You can operate heating, ventilation, and air conditioning (HVAC) systems normally, but turn off energy recovery ventilators or window fans that pull in outdoor air.

The detector must be placed in the lowest livable level of your home (normally the basement if it is used or could be renovated, or the raw ground floor if you lack a cellar). We position it away from drafts, direct vents, fireplaces, laundry sumps, bathrooms, and exterior walls. It'll stay suspended about 1 to 2 meters above ground level to measure breathing zone air accurately.

Yes, absolutely! There is zero disruption or evacuation needed. Our testing processes are quiet, radiation-free, and chemical-free. You should conduct normal, daily routines except keeping outer windows closed.

We offer specialized 'Pre-Purchase Radon testing' with accelerated timelines (typically 5 to 7 days). We supply comprehensive, C-NRPP certified, professional reports that satisfy real estate contract conditions and can include mitigation cost estimates if levels test elevated.

Yes. In fact, newly built properties are often more tightly sealed than heritage structures, trapping bedrock gases inside. Local geologies across Carleton county and the Ottawa River valley release radon continuously. Active ventilation and concrete seal testing are the only ways to guarantee safety profiles.

Active digital monitors track radon concentration hour-by-hour, sensing temperature, relative humidity, and motion tamper alerts. Passive alpha-track devices are static polymer materials used for long-term (90-day to 1-year) tracking, which gets analyzed in a certified national laboratory. Both methods offer perfect accuracy when managed by certified technicians.

Health Canada recommends retesting your home every 5 years, or immediately following major structural changes, foundation sealing, crawlspace expansions, or HVAC furnace installations which altered dynamic pressure values in your basement.
