Radon Mitigation and Testing in Spruce Grove
In Take Action on Radon's 2019 test kit challenge, 61 homes in Spruce Grove, Stony Plain and Parkland County tested through the winter: roughly 4 in 10 read over 100 Bq/m³, and about 1 in 12 over Health Canada's guideline of 200. The far bigger 2024 Cross-Canada Survey of Radon puts about 1 in 6 homes at or over 200 in the census division Spruce Grove shares with Edmonton. Our crews work from Harvest Ridge and Spruce Village out to the acreages and lake homes past Stony Plain. Questions about a test or a result? Call us.

Our Radon Mitigation Work in Spruce Grove
Just a Few of Our Results From the Area
We work in Spruce Grove's newer neighbourhoods, on the acreages around the city, and out at the lake homes west of Stony Plain.
Each system is designed for the house it goes in. Canada's national standard for radon mitigation (CAN/CGSB-149.12-2024, section 1) says a system that is properly designed and installed by certified professionals can lower radon by about 90% or more. How well a system works comes down to who designs and installs it. We've lowered the radon in every home and commercial building we've ever worked on. Every system we install comes with guaranteed results.
Tricky homes are the ones our technicians enjoy most. Even after more than 3,000 homes, we still run into something new now and then, and when we do, the whole team works on it together, so every job has the experience of all our crews across Alberta and BC behind it.
The Three Homes Below
Before Mitigation
120 to 321Bq/m³
After
19 to 34Bq/m³
292→19Bq/m³
Two-storey, Spruce Grove
2010s two-storey · finished basement · sump pit
The owners' own three-month test read 292 Bq/m³. The mechanical room sits away from the outside walls, so the pipe had a longer run to find its way out. A lab test through the next winter came back at 19.
120→20Bq/m³
Newer two-storey, Spruce Grove
2020s two-storey · builder's radon rough-in · gravel under the slab
Under 200 already, but the family wanted it lower still. We sealed the sump and put a fan on the system, and their own monitor has averaged about 20 since.
321→34Bq/m³
Lake home, Seba Beach, Parkland County
2000s lakefront home · part basement, part crawlspace · two sump pits
A high water table, a history of flooding, two sump pits and most of the house over a crawlspace. A lab test the following winter read 34.
All numbers in Bq/m³. The befores are the owners' own tests and monitors; the afters are lab tests, apart from the newer two-storey, read on the owners' monitor. To protect each owner's privacy, home details are approximate, and the photos come from our installs around Spruce Grove rather than always from the home on the card.

Radon Levels in Spruce Grove
What Local Tests Have Found
Spruce Grove is counted in one census division with Edmonton and its neighbours, including Stony Plain and Parkland County. Roughly 1 in 6 of that division's tested homes came in at or over 200 Bq/m³, Health Canada's guideline, and more than half at or over 100, in Evict Radon's 2024 Cross-Canada Survey of Radon.
That is a big sample: 4,397 homes. The only count for the Spruce Grove area by itself is older and far smaller, 61 homes in Spruce Grove, Stony Plain and Parkland County in the winter of 2019, with about 1 in 12 over 200 and about 4 in 10 over 100 (Take Action on Radon community report).
So which number fits your house? Neither one. The 2019 figure looks lower than the region's, but 61 homes is a thin sample, and the report itself warns that levels can vary between neighbouring homes. Your own long-term test is the number that counts. See how other parts of Alberta compare.
Health Canada says radon is the number one cause of lung cancer in people who don't smoke. Radon has no symptoms, so a test is the only way to know. For questions about radon and your health, talk to your doctor or call Health Link at 811. More on radon and your health.

Radon Testing in Spruce Grove
The Best Way to Test
Start with a long-term test from us. Our long-term test kit is the kind of test Health Canada recommends: set it in the lowest level of your home that people use, leave it at least three months, best through a Spruce Grove winter, then mail it to the lab in the prepaid envelope. The lab result comes back to you, and if it's high, call us and we'll go through it together.
Long-Term Radon Test Kit
Lab analysis and a prepaid return envelope included. Free shipping in Alberta and BC.

Free Ways to Test in Spruce Grove
Borrow a radon kit from the library. From October to April, Spruce Grove Public Library lends Alberta Lung's radon kits: a detector, a booklet of instructions and a survey to fill in when you bring it back. Place a hold in the library's online catalogue (TRACpac). Loans run three weeks, with one renewal if nobody is waiting, and only Yellowhead Regional Library members can borrow them.
Or the City's energy kit. The City of Spruce Grove and the library also lend four Home Energy Efficiency Kits, with a radon detector packed in beside a thermal scanner and an air quality monitor. They go out from the North East Branch in Heavy Metal Place to Spruce Grove Public Library card holders.
There can be a wait for either, so check one is free before you count on it:
- Radon Kits and Home Energy Efficiency Kits on the Spruce Grove Public Library's collections page
- Central Branch, 35 Fifth Avenue, and North East Branch, 50 Westwind Drive, in Heavy Metal Place
- Home Energy Efficiency Kits on the City of Spruce Grove's site
Know a library or community centre that could use a radon detector? RadonCare may be able to donate one for your community to borrow. Contact us to ask.
A Word on Free Tests
Free detectors from your library are a good first look. Be careful with a free test from a company that also sells radon systems: a test of only a few days, or a detector in the wrong spot, can show a problem a proper test would not. More on what a short test can and cannot tell you.
Already Own a Radon Monitor?
Plenty of the owners who call us around Spruce Grove do: about 2 in 3 had their own monitor running before they picked up the phone (from our job records). Tell us its average and how long it has been plugged in. Readings over a few days can show a home is high, but they can't show it is low, so a low early number deserves a long-term test. After a system goes in, the same monitor shows you the drop.
Testing spreads on a street, too. When one newer Spruce Grove family had their system put in, they told the neighbours, and several of them tested their own homes.
Child Care
Alberta has no radon testing rule for child care: a 2017 law that would have required it was repealed at the end of 2023 without coming into force (Alberta King's Printer). More on child care and schools.
Spruce Grove Homes and What They Mean for Radon
A Young City
Spruce Grove's homes are, on the whole, much newer than Edmonton's. About 6 in 10 date from 2001 or later and about 1 in 3 from 2011 on; in Edmonton those shares are closer to 4 in 10 and 1 in 5 (Statistics Canada, 2021 census). The houses on our own list skew newer again: roughly 2 in 3 of the Spruce Grove, Stony Plain and Parkland County homes we've worked on date from 2006 or later (from our job records). Newer doesn't mean lower: the 2024 Cross-Canada Survey of Radon found Alberta's newest homes averaging the highest levels yet (p.51-52).
Stony Plain and the Acreages
Stony Plain has about the same share of pre-1981 homes as Spruce Grove, but fewer new ones: about 1 in 5 went up in 2011 or later. Parkland County is the older stock: about half of its homes were built before 1991, and nearly 9 in 10 are single detached houses (Statistics Canada, 2021 census). In one older acreage bungalow we found the furnace sitting on hollow concrete blocks; their open cores got sealed along with the cracks.
When the Builder Left a Radon Pipe
Every home with a builder's rough-in that we've fixed in and around Spruce Grove still needed a fan to get the level down, including houses only a few years old. A capped pipe can save time on the day. Before we use it, we check that it actually reaches the fill under the slab.
A Sump in Almost Every Basement
Sump pits are the rule here: roughly 4 in 5 of the area homes in our job records had one, and so did every home we've done inside the city. Often the sump is the best place to draw from. We bring the pipe up through the lid. An open pit is an easy way in for radon, and Alberta's building code requires sump pit covers to be airtight. The lid also has to stay easy to take off, because the pump needs a check every year. Learn more about sealing a sump pit for radon.
Semis and Duplexes
One Spruce Grove home in 8 is a semi-detached house, close to twice Edmonton's share (Statistics Canada). Radon can be very different from one side of a duplex to the other, so a neighbour's result doesn't tell you yours. Both sides should test. More on condos, townhouses and renters.
Wells and Cisterns
City taps are fed by EPCOR (City of Spruce Grove); out on an acreage, it may be a well or a cistern. In a 2024 study led by the University of Calgary, homes in rural communities averaged up to nearly a third more radon than homes in cities, and the authors put most of that gap down to living near a drilled water well, not to drinking from one. Either way, it's the air in the house that you test.
Lake Homes West of Stony Plain
We haven't met a crawlspace under a house in the city itself. They show up in the rural and lake homes to the west, from Carvel out to Seba Beach, often beside a part basement. A crawlspace gets sealed and drawn from as part of the system. About 1 in 8 Parkland County dwellings had no usual resident on census day (Statistics Canada). If yours is a lake place, test it while someone is living in it, not while it's shut for the season.
Where the Radon Fan Is Installed
Canada's radon mitigation standard only allows a radon fan outdoors where winters are mild, and Spruce Grove is too cold for that (CAN/CGSB-149.12-2024, clause 5.8.1.1, p.30; heating degree days from the National Building Code of Canada 2020, Appendix C). Your fan is installed in a heated space, usually the basement, a utility room or a heated garage, where it lasts longer and stays quiet.
On the homes we've done around Spruce Grove, the pipe leaves through a side wall.
What We Find Under Spruce Grove Floors
Our job reports here show sand under most of the older and acreage floors, and gravel under the newest homes. Gravel often lets one suction point reach the whole slab. In sand, air moves less freely, so careful sealing matters more, and a far corner can need a second point. An addition on its own footing can need a point of its own, and out in the county we've even worked under a wood basement floor laid over sand. Why it matters: how a radon system works.
Radon and the Building Code in Spruce Grove
What New Homes Need, and Since When
Spruce Grove keeps building. About 1 in 3 of its homes went up in 2011 or later (Statistics Canada, 2021 census). For any house whose builder applied after November 1, 2015, the code called for a radon pipe down through the basement slab, capped, and no fan: a starting point, not a working system.

Code Dates for Spruce Grove
- November 1, 2015: For homes the builder applied to build after this date, Alberta's first radon rough-in, a capped pipe through the basement floor (the code took effect May 1, 2015, with a six-month changeover; Government of Alberta).
- December 1, 2019: For homes the builder applied to build from this date, the pipe has to be labelled (National Building Code, Alberta Edition 2019; Government of Alberta).
- May 1, 2024: For homes the builder applied to build from this date, the current code (National Building Code, Alberta Edition 2023). Still no fan required (Government of Alberta).
The area's own 2019 Take Action on Radon report is blunt about the pipe: "This is not a radon mitigation system, but simply a rough-in." Its advice is a 91-day test in the heating season.
Moving into a newer home around Spruce Grove? Look for the radon pipe in the basement (newer ones are labelled), then test once you've moved in.
What It Means for Your Home
A rough-in is a head start, not a radon system: there is no fan, so a newer home still needs a test, and we test the pipe before using it. More on radon in the Alberta Building Code.
Spruce Grove's Own Inspections
The City of Spruce Grove inspects new homes with its own Safety Codes Officers. In December 2025 it rewrote its safety codes bylaw to spell out their inspections (City of Spruce Grove), and its inspection list for a new house has four stages: foundation, framing, insulation and final.
Stony Plain and the acreages of Parkland County build to the same Alberta code.

Spruce Grove Radon Questions
Is Radon a Problem in Spruce Grove?
Yes. In the 2024 Cross-Canada Survey of Radon, which counts Spruce Grove with Edmonton and the area around it, about 1 in 6 homes tested at or above Health Canada's guideline of 200 Bq/m³. The homes shown above read 120 to 321 Bq/m³ prior to mitigation, which brought them down to 34 Bq/m³ or lower. A long-term test of your own home is how you find out where yours sits.
Is Radon Lower in Spruce Grove Than Elsewhere in the Region?
The one local count came in lower, but we wouldn't lean on it. Of the 61 Spruce Grove, Stony Plain and Parkland County homes tested in 2019, about 1 in 12 were over 200. In Take Action on Radon's own Edmonton count, in the winter of 2023, about 1 in 4 of 163 homes were over 200 (Edmonton community report). The samples are small, years apart and from different homes. The 2024 survey's Edmonton-area 1 in 6 takes in Spruce Grove too, so it can't settle the question either. Every house is its own case. Test yours.
My Newer Spruce Grove Home Has a Radon Pipe. Do I Still Need to Test?
Yes. Alberta's code asks for the pipe, never for a fan. The pipe ends in a cap in your basement, and a capped pipe moves no air. Around Spruce Grove, every builder's pipe we've worked on still needed a fan. Test first; if the result is high, we check the pipe before we use it.
Can I Borrow a Radon Detector in Spruce Grove?
Yes, two ways, both through Spruce Grove Public Library: Alberta Lung's radon kits from October to April, and the City's Home Energy Efficiency Kits, which include a radon detector. See Radon Testing in Spruce Grove. If you'd rather have an answer this winter without a wait, our long-term test kit comes with free shipping in Alberta.
Is Radon Different on an Acreage Near Spruce Grove?
The test is the same; the houses aren't. County homes are older on average than city ones, some run on a well or a cistern, and the floors we open out there are more often sand than gravel, so sealing matters more. Test through the winter and call us with the number.
Do You Work in Stony Plain and Parkland County?
Yes. Our area runs from Acheson west through Stony Plain, Carvel, Duffield and Wabamun to Seba Beach and Tomahawk, acreages included. For Edmonton and St. Albert, see their own pages. Not sure we reach you? Give us a call.
When Should I Test My Spruce Grove Home?
In the heating season. A long-term test started in October or November runs its whole three months while the windows are shut and the furnace is on. Spruce Grove Public Library lends its radon kits only from October to April for the same reason: winter, it says, is the best time to test in Alberta. See Radon Testing in Spruce Grove.
How Much Does Radon Mitigation Cost in Spruce Grove?
A radon system costs a fraction of the price of air conditioning. The price depends on your home. In town it's usually a sealed sump; out at the lakes, a crawlspace is often part of the job. With a few details we can usually quote it on the same call. See what changes the price.
Why Doesn't RadonCare Offer Free Radon Tests?
Because we want the test done right. A proper test runs for at least three months in the lowest lived-in level of your home, and we only recommend a system after a long-term test. For a free first look, borrow a detector from your library, then follow up with a long-term test.
Is There a Grant for Radon Mitigation in Spruce Grove?
At the time of writing (October 2026), there is no Alberta, regional or city grant for radon mitigation. Anything we missed? Let us know. Two charities can help: the Canadian Lung Association's Lungs Matter program, if you have been diagnosed with lung cancer, or your household has a low to moderate income, and Alberta Lung, in radon season, if you have been affected by lung cancer. See grants and help paying.
