What radon means for Carstairs homeowners
Radon is a natural radioactive gas that forms when uranium in soil and rock breaks down. It seeps into homes through cracks, drains and gaps, you can’t see or smell it, and breathing it for many years raises your risk of lung cancer. Testing is the only way to know your level. Here is what matters for homes in Carstairs.
Homes in Carstairs
Newer homes may be full-basement builds with a sump. Older homes may have crawlspaces or partial basements, and acreages around town may have additions, shops and private wells and septic.
What to know in Carstairs
The foundation decides the fix. A full basement uses a slab suction system, a crawlspace uses a sealed membrane with suction beneath it, and a home with both uses a combination. We confirm each with a communication test.
Which foundation is hardest to fix?
None is hard. Crawlspaces and mixed foundations take more planning than a single slab, and our written quote reflects that before work starts.

Radon testing in Carstairs: mixed foundations and acreages
Newer homes
We test the lowest level, and note the sump and any rough-in pipe, which we may be able to activate if the result is high. Radon changes from day to day, so a proper test runs at least 91 days.
Older homes with crawlspaces
We test the lowest level above the crawlspace, and consider the bare soil below, which is an entry path for radon into the space above. Every test is set up and read by C-NRPP certified professionals.
Acreages and outbuildings
Shops and other detached buildings can have their own foundations. We decide which to test. Health Canada’s guideline is 200 Bq/m³ (5.4 pCi/L), and 1 pCi/L equals 37 Bq/m³. Above that, it recommends reducing radon within one year, sooner if the level is higher.
Radon mitigation in Carstairs homes and Mountain View County properties
Slab systems
We core the slab, form a suction pit and run a pipe up from it, with the fan on the pipe right above the suction point and a manometer showing it is working. The pipe exits through the side of the house. Every system is designed and installed by C-NRPP certified professionals.
Crawlspace systems
We cover the soil with a sealed membrane and apply suction beneath it. If your crawlspace has bare soil, it needs this different approach from a slab system.
Gauge and retest
A manometer on the pipe shows the fan is running. A 91-day retest after install confirms the number dropped. In most homes a system can reduce radon by up to 95%.

Thinking about a DIY radon test?What to know before you buy a kit
- Choose a long-term testHealth Canada recommends testing for at least 91 days, ideally 3 to 12 months. Short-term kits, including many library kits, only give a rough idea and aren’t appropriate for deciding on mitigation.
- Use an approved deviceHealth Canada recommends long-term devices that have passed C-NRPP performance testing. For electronic monitors, it strongly recommends only devices on the C-NRPP consumer list.
- Know the kit typesAlpha track detectors and electret ion chambers are sent to a lab for results. Electronic radon monitors show readings on a screen or app, but check that they store at least three months of data.
- Place it correctlyUse a bedroom, living room or office on the lowest lived-in level, at least 30 cm above the floor and 30 cm from walls, and 1 m from windows, doors and vents. Avoid kitchens, bathrooms, laundry rooms, sump holes and foundation cracks. One detector is enough.
- Follow the instructions exactlyDon’t move or tamper with the device. Mail lab kits back promptly and before the expiry date. If a device is dropped or damaged, repeat the test with a new one.

Do I need to test if my home is older?
Yes. Age does not predict radon. Foundation condition, soil contact and airflow matter more than the year the house was built.

We test the lowest level above it. If mitigation is needed, the crawlspace is covered with a sealed membrane and ventilated from beneath.
Can I test a shop or detached building on my property?
Yes. Any space can be tested, and we assess the property to place detectors where they will give a clear result.
