200 Bq/m³ action level.
Health Canada recommends mitigation in any home measuring above 200 Bq/m³ over a long-term (≥ 90 day) test. We report against this threshold so you know exactly where you stand.
Why it matters
8×
More air than food.
Every day, your body takes in 8× more air than food — yet air rarely gets filtered, questioned, or checked.
Daily intake
You eat a few kilos. You breathe a lot more.
Food intake
1.5–2.5kg/day
Air intake
13.5–18kg/day
Your body’s defenses
One system filters.
The other doesn’t.
Food → Digestive
Strong, layered defenses.
- Stomach acid destroys microbes
- Enzymes break down substances
- Liver detoxifies what passes through
Air → Respiratory
Fast, direct, unfiltered.
- Air reaches alveoli in seconds
- Radon, VOCs & CO enter the bloodstream directly
- PM2.5 & PM10 deposit in lung tissue
80–90%
of your life is spent indoors
Indoor pollutant levels are often several times higher than outdoor air.
What you breathe indoors
Ten common indoor pollutants.
Most homes have several of these at low levels all the time — the question isn’t whether they’re present, it’s whether the concentration is high enough to matter.

Why it matters
Carcinogenic — every known PM, VOC, and CO
“We test” covers the five pollutant classes on our service list. The others (CO₂, NO₂, O₃, tobacco residues) we screen for during consultation and refer to specialist labs when needed.
The cost of inaction
What poor air quality does to you
Continuous. Invisible. Often more dangerous than what’s on your plate.
- Fatigue & poor focus
- Headaches & sleep issues
- Worsened asthma & allergies
- Cardiovascular disease
- Long-term lung cancer risk
Standards we follow
The frameworks behind every test
Our measurements are aligned with national programs and the local realities of BC homes.
CARST
Canadian Association of Radon Scientists & Technologists.
CARST is the national body for radon professionals in Canada. Membership means continuing education, research access, and accountability to professional standards.
C-NRPP
Canadian National Radon Proficiency Program.
C-NRPP defines the methodology for measurement and mitigation in Canada — including device placement, test duration, QA procedures, and reporting. We follow it on every job.
BC-grown
Independent & local to Vancouver Island.
We’re a Vancouver Island team — familiar with coastal geology, crawl-space construction, and the seasonal pressure differences that affect radon readings on the Island.
Breathing isn’t optional.
Monitoring indoor air quality isn’t a luxury — it’s a fundamental necessity for protecting your health.
