Why radon matters in Calgary

Radon is the #1 cause of lung cancer in non-smokers

No need to panic — this is a solvable problem. But it's worth knowing the facts for our region.

  • Radon is a colourless, odourless gas that seeps up from the ground into homes through the foundation.
  • Calgary and southern Alberta sit on uranium-bearing Prairie bedrock. Alberta is one of Canada's higher-radon provinces, and many Calgary homes test above Health Canada's 200 Bq/m³ guideline.
  • Levels vary house to house. The only way to know yours is to test — then mitigate if it's high.
Check your neighbourhood's radon risk
200 Bq/m³ Health Canada action guideline. WHO recommends acting at 100 Bq/m³. Above these, mitigation is recommended.
< 50 Bq/m³ Typical result we deliver after a sub-slab depressurization system is installed and re-tested.

Simple, proven process

How radon mitigation works

Four steps from "worried about my reading" to "below guideline and verified."

1

Test your home

Start with a certified radon test (or bring us your existing result). This sets the baseline for your Calgary home.

2

Custom mitigation plan

We assess your foundation, sump, and slab, then design the right system and give you a clear, fixed quote.

3

Install the system

We install a sub-slab depressurization system that vents radon safely outside — usually in a single day.

4

Free re-test to confirm

After the system runs, we re-test to prove your level is below the 200 Bq/m³ guideline. Guaranteed.

What's included

Radon services for Calgary homes

Testing through mitigation and verification — handled by one certified local team.

Sub-slab depressurization

The gold-standard fix. A sealed pipe and quiet fan pull radon from under your slab and vent it above the roofline, before it enters your living space.

Sump-pump & slab sealing

We seal sump pits, cracks, and slab penetrations so the system works efficiently and radon has no easy path back in.

Radon testing in Calgary

Certified short- and long-term testing so you know your true level before and after. Testing first is the honest way to start.

Post-mitigation verification

Every install ends with a follow-up test. We don't call it done until your reading is comfortably below the guideline — in writing.

Questions, answered

Radon mitigation FAQ

The things Calgary homeowners ask us most.

How much does radon mitigation cost in Calgary?
Most single-family Calgary homes fall in the $2,000–$3,500 range for a full sub-slab depressurization system, install, and verification re-test. Larger homes or complex foundations with multiple sumps can cost more. You get an exact, fixed price after a free on-site assessment — never a guess over the phone.
What are safe radon levels?
Health Canada's guideline is 200 Bq/m³ — you should take action if your home tests above that. The World Health Organization recommends acting at 100 Bq/m³. There's no such thing as a perfectly "zero" level since radon occurs naturally, but our goal is to get your home comfortably below 200, and in practice we usually land well under 50 Bq/m³.
How long does radon mitigation take?
Most installations are done in a single day — often just a few hours. After the system is running, a verification test period follows (typically a couple of days for a short-term confirmation test) so we can prove the level has dropped below the guideline before we call the job complete.
Do I need to test for radon first?
Yes — testing first is the honest way to do this. You shouldn't pay to mitigate a problem you haven't confirmed. If you already have a recent radon test result, bring it and we'll work from that. If not, we'll arrange certified radon testing in Calgary before recommending any system.
Is radon a big problem in Calgary?
Calgary and southern Alberta sit on uranium-bearing Prairie bedrock. Alberta is one of Canada's higher-radon provinces, and many Calgary homes test above Health Canada's 200 Bq/m³ guideline. That said, radon varies house to house — your neighbour's level tells you nothing about yours. The only way to know is to test. You can check your neighbourhood's radon risk on our map to see the general picture.
How does a radon mitigation system actually work?
A sub-slab depressurization system uses a sealed pipe and a quiet inline fan to draw radon from beneath your basement slab and vent it safely above your roofline, before it can enter your living space. We also seal the sump, cracks, and slab penetrations so the system runs efficiently. It's the method C-NRPP and Health Canada consider the standard fix.
