No one deserves to live with hidden moisture or mould at home.
Four Facts About Mould & Dampness
Radon is invisible, but measurable
Radon is in your home & maybe at unsafe levels. It is more common in BC
Radon causes "Lung Cancer"
Radon is manageable & preventable
-
Mould is common in damp buildings, but preventable and manageable.
-
Mould grows where moisture persists
-
Indoor mould can affect air quality & respiratory health
-
Moisture problems can often be identified early
-
Most mould issues are solvable with correct assessment
Mould could be invisible or hidden behind the wall—but it’s easy to measure and mitigate reduce
Mould grows where moisture exists
• Roof leaks, plumbing leaks, poor ventilation
• Condensation in bathrooms and basements
• Flooding or chronic dampness
Mould may affect respiratory health
• Associated with asthma symptoms and flare-ups
• Linked to coughing, wheezing, and airway irritation
• Children and those with existing respiratory conditions may be more sensitive
You cannot always see the source
• Visible mould is sometimes only the surface issue
• Hidden moisture behind walls or under flooring may be the driver
• Smell alone is not reliable
Assessment focuses on identifying moisture sources — not just visible growth.
Most problems are manageable
• Improve ventilation
• Correct leaks
• Control indoor humidity (ideally below ~50%)
• Remove contaminated materials when needed
The key is identifying the source of moisture.
The World Health Organization notes that indoor mould growth is strongly linked to excess indoor moisture.
WHO and Health Canada both recognize damp indoor environments as a public health concern.
If it’s elevated, most homes can reduce levels effectively.
Carbon Monoxide vs. Radon vs. Mould
What BC Homeowners Should Know
Carbon monoxide causes acute poisoning.
Radon increases long-term cancer risk.
Mould and dampness are linked to respiratory irritation and asthma.
Mould is less dramatic — but persistent moisture can quietly affect indoor air quality over time.
Testing and assessment help you act early.
Radon is less well known because it builds up quietly inside homes over many years and
causes no symptoms until serious illness develops.
Without testing, radon can go unnoticed for decades.
Testing is the only way to know your home’s radon level.
Health Canada’s guideline is 200 Bq/m³. Above that, action is recommended.

Step 3: We perform moisture measurements and, when justified, air or surface sampling using professional methods.
Step 4: You receive clear, plain-language results explaining what was found — and whether action is necessary.
Step 5: If remediation is warranted, we explain appropriate next steps and when specialist remediation companies should be engaged.
Typical Cost (Explained Before You Decide)

Radon has no smell and usually has no warning signs. The only way to know your home’s level is to test. If levels are high, they can be reduced.
Radon is a leading cause of lung cancer among non-smokers in Canada.
-
Radon concentrations are often highest on lower levels of the home.
-
Exposure depends on where you spend the most time—especially bedrooms and sleeping areas.
No need for alarm — just measure it.
No Need for Alarm — Just Assess the Moisture.
Here’s why professional testing matters—and why families choose us.
Why families choose SafeHomeBC for radon testing

We help families understand real radon risk and take the right next step—without fear-based messaging or unnecessary services.
Why professional radon testing matters
Correct identification matters
Visible mould does not always reflect the underlying moisture source.
Testing without moisture evaluation can be misleading.
The right scope, the first time
Air sampling is not always necessary. In many cases, moisture control solves the issue.
Humidity and building patterns matter
BC’s coastal climate increases condensation risk. Assessment must reflect local housing types.
-
Correct placement matters
Radon levels can vary widely within the same home. Incorrect placement can lead to false reassurance or overestimation. In some homes, multiple devices are needed to run concurrent tests and reflect real exposure
-
The right test, the first time
Short-term and long-term tests serve different purposes. Choosing the wrong test can delay answers, extend exposure time, and increase costs.
-
Timing and conditions matter
Radon levels change with season, weather, and ventilation habits. Results that ignore these factors can be misleading.

Testimony
Sara (Home Daycare Owner, Coquitlam)
One parent asked if we test for radon, and that made me look into it. SafeHomeBC walked me through everything, helped place the monitors properly, and kept the process calm and affordable. We chose a longer test so parents could feel confident—and now I have an official report on file. It gives parents real peace of mind.
Read Sara’s full experience → It gives parents peace of mind knowing we’ve tested and have the report on file. I run a home daycare, and I’m really glad I went through this process—I actually felt I should share our experience. One parent who moved here from the U.S. asked if we test for radon. In their previous city, it was expected for daycares. I hadn’t thought about it before, since it’s not required here, but for me this was about safety and peace of mind for the kids and their families. I called SafeHomeBC just for guidance and was surprised how affordable it was. They started with a short planning visit, explained everything in plain language, and helped decide where the monitors should go, which really matters in a daycare. We chose a longer test so parents could feel confident in the results, and the planning visit cost was applied to the testing package. The process was calm, professional, and didn’t disrupt the children at all. Now I have an official radon report on file for my daycare—and I feel confident telling parents that we’ve taken this step seriously.

Customer Reviews
Jen (Parent, Port Moody)
I wanted clear answers for my kids—not fear.
During my second pregnancy, I learned that radon can be present in some homes here. I wanted clear answers without panic. SafeHomeBC took the time to explain everything in plain language, helped choose the right test, and never pressured us. The process was affordable and reassuring.
Read Jen’s full experience → ... During my second pregnancy, I learned that radon can be present in some homes in Coquitlam. I wasn’t looking to panic—I just wanted clear, reliable information about our home and my children’s health. I contacted SafeHomeBC and immediately felt listened to. They explained radon in plain language, talked through testing options, and helped us decide what made sense for our situation. I never felt rushed or pressured into anything. The testing cost less than I expected, the visit was straightforward, and the results were explained clearly. Most importantly, I walked away understanding what the numbers meant and what—if anything—we needed to do next. It gave me real peace of mind, especially during pregnancy.
Akram (Home Buyer, Vancouver)
We got clear answers fast—and a certified report we could rely on.
We were buying a home and needed answers fast. SafeHomeBC explained the options clearly and suggested a short-term (they call it Tier 1 test) to screen quickly. It was affordable, low-disruption, and gave us a certified report we could rely on. The whole process took a few days and made a stressful situation much easier.”Pull quote (under the card):“We got clear answers fast—and a certified report we could rely on.
Read Akram's full experience → We were in the middle of buying a home and needed clear answers quickly. I called SafeHomeBC and spoke with someone who walked me through the process right away. They explained the difference between short-term and long-term testing and suggested a short-term test (Tier 1) to screen quickly, given our timeline. It was affordable, and they also explained what a longer test would show if we had more time. There was no pressure—just clear options. We wanted a certified report in case there were questions or a dispute later, and that’s exactly what we got. The testing took about four days, didn’t create any mess around the house, and was handled professionally from start to finish. It took a lot of stress out of the buying process.
