Radon Testing Guide for Homeowners
Welcome to Flood Ready’s Radon Testing Guide! If you’re a homeowner in Toronto, Markham, or the GTA, this page is your go-to resource for safeguarding your family from radon—a colorless, odorless gas that’s the second-leading cause of lung cancer in Canada. While our previous Flood Prevention Checklist tackled water damage, this guide addresses an equally pressing but often overlooked risk. We’ll cover what radon is, why it’s a concern, how to test for it, and what to do if levels are high—all customized to your local context. Let’s make your home a true safe haven!
What Is Radon and Why Should You Care?
Radon is a naturally occurring radioactive gas that seeps into homes from the soil beneath them. Invisible and undetectable without testing, it poses a significant health risk. Here’s why GTA homeowners need to pay attention:
- Health Impact: Health Canada links 16% of lung cancer deaths—over 3,000 cases yearly—to radon exposure.
- Local Risks: Areas like Scarborough bluffs in Toronto and bedrock zones near Markham have higher radon potential due to geology.
- Basement Hotspots: Radon accumulates in basements, where families often relax or play.
- Constant Threat: Unlike seasonal flooding, radon risks persist year-round, peaking in winter when homes are sealed.
- Simple Solution: Testing is affordable and straightforward, and mitigation can eliminate the danger.

Your Step-by-Step Radon Testing Guide
Follow these steps to measure radon levels accurately and take control of your home’s safety.
1. Understand Your Testing Options
Choose the method that fits your needs:
- Short-Term Test (2-7 Days):
- Uses affordable kits like charcoal canisters ($20-$50).
- Provides a quick snapshot but may miss fluctuations.
- Long-Term Test (3+ Months):
- Uses alpha-track detectors ($40-$60).
- Health Canada’s recommended choice for reliable averages.
- Professional Testing:
- Flood Ready offers certified testing with digital monitors—fast, precise results.
Local Tip: Test in winter (November-February) when windows are closed, and radon levels are highest.
2. Set Up Your Test
Ensure accuracy with these setup tips:
- Placement:
- Place the kit in the lowest lived-in area (e.g., basement family room, not a crawlspace).
- Position it 50 cm off the floor, away from windows, vents, or appliances.
- Conditions:
- Keep windows and exterior doors closed 12 hours before and during testing.
- Avoid using exhaust fans or air purifiers that vent outside.
Where to Get Kits: Find them at Home Depot, Canadian Tire, or order from Health Canada’s approved list. Or, let Flood Ready handle it for you!
3. Analyze Your Results
Understand your readings and next steps:
- Safe Level: Below 200 becquerels per cubic meter (Bq/m³).
- Action Threshold: Above 200 Bq/m³—mitigate within 1-2 years (sooner if over 600 Bq/m³).
- GTA Context: Local averages range from 50-150 Bq/m³, but some homes hit 400+ Bq/m³.
What’s Next: Send your kit to a lab (included with most kits) or contact Flood Ready for a free results review.
4. Mitigate High Radon Levels
If levels are elevated, act quickly:
- Ventilation:
- Install a radon mitigation system (e.g., sub-slab depressurization) to vent gas outdoors.
- Cost: $1,500-$3,000, depending on home size.
- Sealing:
- Seal foundation cracks and sump pits to block entry points.
- Expert Help:
- Flood Ready’s certified technicians offer tailored solutions—explore our Radon Mitigation Services.
Common Radon Testing Mistakes to Avoid
Don’t let these missteps compromise your results:
- Testing in Summer: Open windows dilute radon—test in cooler months instead.
- Wrong Placement: Avoid kitchens or bathrooms; humidity skews readings.
- Ignoring High Levels: Delaying mitigation risks your family’s health.
- DIY Pitfalls: Improper sealing can trap radon—trust professionals for fixes.
With Flood Ready, you’ll navigate testing and mitigation with confidence.
