Why it matters
8×
Every day, your body takes in 8× more air than food — yet air rarely gets filtered, questioned, or checked.
Daily intake
Food intake
1.5–2.5kg/day
Air intake
13.5–18kg/day
Your body’s defenses
Strong, layered defenses.
Fast, direct, unfiltered.
80–90%
of your life is spent indoors
Indoor pollutant levels are often several times higher than outdoor air.
What you breathe indoors
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.

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
Continuous. Invisible. Often more dangerous than what’s on your plate.
Standards we follow
Our measurements are aligned with national programs and the local realities of BC homes.
200 Bq/m³ guideline.
If a long-term test (at least 91 days) averages above 200 Bq/m³, Health Canada recommends reducing radon within 1 year — sooner if the level is higher. We compare your long-term result with this guideline and explain what it means.
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.
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.
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.
