Radon Testing & Mitigation in Black Diamond, Alberta
Black Diamond, now part of the Town of Diamond Valley, sits on the slopes above the Sheep River. Depending on your lot, your house may be a walkout, a partial basement or an older foundation, and we plan around the slab you actually have.

Health Canada recommends action when the long-term average is above 200 Bq/m³. Short tests are only a snapshot. 1 pCi/L ≈ 37 Bq/m³.
What radon means for Black Diamond 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 Black Diamond.
Homes in Black Diamond
Homes on slopes may be walkouts, where one wall is at grade and the others are buried. Older homes may have partial basements, additions or crawlspaces, and floors that were cut for plumbing or drains over the years. We look at what yours has.
What to know in Black Diamond
On a walkout, the buried side is where soil gas has the most contact with the house. We test the lowest level, and if mitigation is needed we plan the suction point toward the buried side of the slab. Older cracked or patched slabs are common entry points and are sealed as part of the work.
Does a walkout basement have less radon?
Not necessarily. A walkout has one side at grade, but the rest of the slab and the buried walls are still in contact with the soil. Test the lowest level.

Radon testing in Black Diamond: walkouts, older basements and sloped lots
Walkouts
We place the detector in the main lower-level room, away from the walkout door and windows, where outside air would pull the reading down. At least 30 cm off the floor and 30 cm from exterior walls. Radon changes from day to day, so a proper test runs at least 91 days.
Older homes with patched slabs
Patched floors, old drains and gaps at pipe penetrations are common in older homes. We note them while we set up so they can be sealed if you need mitigation. Every test is set up and read by C-NRPP certified professionals.
Additions and crawlspaces
If an addition sits on a different foundation, it can read differently. We decide which spaces need their own detector. 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 Black Diamond homes on sloped lots
Suction point for a walkout
We usually place the suction pit toward the buried side of the slab, where soil contact is greatest, and run a communication test across the floor to confirm it pulls everywhere. Every system is designed and installed by C-NRPP certified professionals.
Fan and exit point
The fan mounts on the pipe above the suction point inside the house, and the pipe exits through the side of the house. On a sloped lot we choose the exit wall to suit the grade, clear of windows, doors and air intakes.
After install
A manometer on the pipe shows the fan is pulling. We recommend a 91-day retest to confirm the number dropped, and another after any renovation that changes the slab or drains. 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.
