What radon means for Langdon 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 Langdon.
Homes in Langdon
Langdon homes can range from recent builds to older farmhouses and acreage homes. A newer home may have a radon rough-in pipe, an older one may have an addition, a crawlspace or a partial basement, and rural lots may add a well and septic system to plan around.
What to know in Langdon
There is no community-level radon number for a hamlet this size, and one would not tell you much, because radon changes from house to house. The only number that applies to you is a long-term test in your own home, taken at the lowest level.
Is there a radon figure for Langdon?
Not one you can rely on. Radon depends on each home’s foundation, soil contact and airflow, so a neighbour’s result does not describe your house. A 91-day test does.

Radon testing in Langdon: new builds, farm homes and acreages
New builds with a rough-in
We test the lowest level and note whether a capped rough-in pipe is present and where it ends. If the result is high, a rough-in can usually be activated, which is quicker than starting from scratch. Radon changes from day to day, so a proper test runs at least 91 days.
Older and rural homes
Older houses can have additions on a different foundation, patched floors or a crawlspace. We test the lowest level and decide whether an addition needs its own detector. Every test is set up and read by C-NRPP certified professionals.
Detached buildings
A shop, garage or other detached building has its own slab and can read differently from the house. We assess the property and place detectors to match. 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 Langdon: rough-ins, retrofits and acreages
Activating a rough-in
We run a communication test to confirm the pipe reaches the gravel under the slab, fit the fan on the pipe right above it, add a manometer and seal the slab openings. The pipe exits through the side of the house. Every system is designed and installed by C-NRPP certified professionals.
Retrofits without a rough-in
We core a hole through the slab, form a suction pit and run a pipe up from it, with the fan mounted on the pipe right above the hole. The exit point is chosen clear of windows, doors and air intakes.
Wells and septic
On rural lots we plan the drilling point and pipe route so wells, septic fields and buried lines are not disturbed. In most homes a system can reduce radon by up to 95%.
How much does radon testing and mitigation cost in Langdon?
Langdon homes with a rough-in are typically the simplest to fix, because the pipe is already under the slab. Retrofits and homes with more than one foundation take more planning. Your written quote confirms the scope and price before work begins. 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 there a radon figure for Langdon?
Not one you can rely on. Radon depends on each home’s foundation, soil contact and airflow, so a neighbour’s result does not describe your house. A 91-day test does.
Are the radon professionals serving Langdon C-NRPP certified and licensed?
Yes. Our radon professionals are C-NRPP certified, the Canadian National Radon Proficiency Program, which is the national standard for radon measurement and mitigation in Canada, and we are licensed to work in Alberta. Your test and your system in Langdon are handled by C-NRPP certified professionals, and you can ask to see our certification at any time.
Do you serve Langdon?
Yes. Langdon is east of Calgary, and we book tests, quotes and installs there.
How much does radon testing cost in Langdon?
$99 for a 91-day test with set-up, pick-up and your results explained. If you choose First Choice Radon for mitigation after the result, the $99 is reimbursed on your quote.
Does my newer Langdon home need a radon test?
Yes. A rough-in pipe prepares a home for mitigation but does not reduce radon. Airtight newer homes can hold radon in, so test the lowest level.
Do acreage homes with a well and septic need testing?
Yes. Radon comes from the soil under the foundation, not from the size of the lot. We plan any mitigation around the well and septic.
Can a farmhouse or older home be fixed?
Yes. We seal cracks and old openings, then add a suction point and a fan sized for the slab or a sealed membrane for a crawlspace.

Yes. See Chestermere and Strathmore, both nearby on Highway 1.
