What radon means for Rocky View County 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 Rocky View County.
Homes in Rocky View County
Rocky View properties often combine more than one structure: a house with a basement, a crawlspace or a slab addition, plus perhaps a detached garage, shop or other building. Many are on private wells and septic, and newer homes may have a radon rough-in.
What to know in Rocky View County
Radon gets into each foundation separately, so one result may not describe the whole property. A full basement may need a slab system, a crawlspace a sealed membrane, and a slab addition its own suction point. Where the house has a rough-in, we check it first.
My property has a house and several other buildings. What gets tested?
Any space can be tested. We start with the main house, then add any additions or detached buildings, and choose placement so the results are clear.

Radon testing across Rocky View County acreages
The main house
The first detector goes on the lowest level of the main house, placed per Health Canada guidance: 30 cm or more above the floor, 30 cm from exterior walls and at least 1 m from windows, doors and vents. Radon changes from day to day, so a proper test runs at least 91 days.
Additions and detached buildings
An addition on a different foundation can read differently from the original house, so we decide whether it needs its own detector. Every test is set up and read by C-NRPP certified professionals.
Shops, studios and detached buildings
A shop or studio has its own slab and can read differently from a house, so it can be tested too. 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 for multi-foundation acreage homes
Combining systems
Different foundations can be served by separate suction points that exit through one vent or by separate vents. We design around your layout and confirm each area with a communication test. Every system is designed and installed by C-NRPP certified professionals.
Activating a rough-in
If your newer home has a capped pipe, we test that it reaches the gravel under the slab and add a fan, gauge and sealing. It is usually the lowest-cost route.
Gauge, label and retest
Each system has a manometer and a label. A 91-day retest confirms the number dropped, and we suggest retesting after any new addition or foundation work. In most homes a system can reduce radon by up to 95%.
How much does radon testing and mitigation cost in Rocky View County?
Rocky View quotes depend on the number of foundation types, which we confirm on a site visit. Single-slab homes with a rough-in are the starting point, and your written quote lists the scope. Both services are done by C-NRPP certified professionals.
One price for a full 91-day radon test. If your results show you need mitigation and you choose First Choice Radon, the $99 is reimbursed on your mitigation quote.

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.

Is a multi-foundation home harder to fix?
It takes more planning, not more difficulty. We assess each foundation, run communication tests and quote the combined scope up front.
Do wells and septic affect mitigation?
Only the layout. We plan drilling points, pipe routes and fan locations to stay clear of wells, septic fields and buried lines.
Is there a county-wide radon figure?
The 2024 Cross-Canada survey reports regional results, and about one in five Prairie homes are at or above the 200 Bq/m³ guideline. It cannot say where your home falls, which is why a test matters.
