Why it matters
Every home on PEI should be tested
Radon seeps up from the soil through cracks, sumps and gaps in the foundation and collects indoors, especially in winter. No part of Canada is radon-free, and two houses side by side can have very different levels.
Health Canada's guideline is 200 Bq/m³. If a test is above that, Health Canada recommends taking action, and hiring a contractor certified as a radon mitigation professional through C-NRPP.

| Long-term test | At least 3 months, ideally through the heating season. This is the test Health Canada's guideline is based on. Alpha track test kits |
|---|---|
| Short-term test | A screening test of at least 72 hours, used when there's a deadline, such as a home sale. Real estate testing |
| After mitigation | A 48-hour clearance check, then ongoing monitoring with Radon Shield™. |

Long-term test kits
Alpha track radon test kits
For the most accurate picture of your home's radon level, Cleya Ltd. sells alpha track test devices. They provide the 91-day long-term test that Health Canada recommends, so the result reflects your home's levels over a full season, not just a few days.
Planning to apply for mitigation funding?
A lab-readable alpha track test is required to qualify for funding that offsets some of the cost of radon mitigation, such as the Canadian Lung Association's Lungs Matter: Radon program. Start with this test so your result counts, and see the Lung Association's page for funding amounts and eligibility.

How mitigation works
From high readings, to safe home, usually in a day
We install an active sub-slab depressurization system: a quiet fan pulls radon from under your foundation through a sealed pipe and vents it outside before it can enter your home.
Assess
We review your test results and look at the foundation, sump and layout to design the right system for your home.
Seal
Openings where soil gas gets in are sealed, including sump pits when the design calls for it. If yours doesn't need sealing, we'll tell you.
Install
A Fantech radon fan and RadonX pipe are installed, labelled and fitted with a gauge so you can see the system is working.
Confirm
A 48-hour clearance report confirms the result, then Radon Shield™ keeps monitoring for the first year at no extra cost.
What we install
Equipment we trust
- Fantech RN2EC and RN4EC radon fans. Fantech builds its fans in Bouctouche, New Brunswick. About Fantech radon fans
- RadonX pipe, made for radon systems and clearly marked for soil gas.
- A pressure gauge and system labels on every install, so you can check at a glance that it's running.
Work follows Canada's radon mitigation standard for existing homes, CAN/CGSB-149.12.

- A radon report is prepared every month for your file.
- After the first year, you can renew your monitoring coverage. Ask us for details.
The Radon Reduction Guarantee
Offered through our partnership with Radon Repair
Once your system is installed and passes its clearance check, your radon levels are guaranteed to stay below 100 Bq/m³, half of Health Canada's 200 Bq/m³ guideline. Brief spikes from weather can happen, so if your levels stay above 100 Bq/m³ for more than 48 hours, Radon Shield™ alerts us and we'll call or visit to find out why and set it right.

What clients say
★★★★★
“I highly recommend Zach and Cleya Diagnostics Ltd.! From start to finish, Zach was professional, knowledgeable, friendly, and took the time to explain everything clearly. He did an amazing job installing our radon mitigation system and made the whole process easy and stress-free. The quality of his work was excellent, and you can tell he genuinely takes pride in what he does. He was reliable, thorough, and left everything clean and tidy when the job was finished.”
★★★★★
“Zack was great to work with. Communication was excellent throughout the process. He was on time. Project completed in a day as scheduled. He noticed the sump pump did not need to be sealed off which saved us a bit of money. Our radon level is now at a safe level.”
Client testimonial
“Cleya Diagnostics did a top notch job from start to finish when helping me to reduce the radon level in my basement. Zack went through the entire process and explained each step clearly and professionally. With the new system in place including a monitor for future readings, my mind is now at ease going forward. Thanks again for your friendly assistance! Much appreciated!!”

New homes
Building new? Plan for radon now.
Canada's standard for new buildings describes three levels of radon control. Planning for them during construction is far easier than adding them later.
Level 1
Radon rough-in
A gas-permeable layer, soil gas barrier and a capped pipe under the slab, ready for a fan later. Most provincial codes already require something similar.
Level 2
Passive stack
The pipe runs up through the house and out above the roof. Research shows passive stacks reduce radon by 40 to 90%.
Level 3
Active system
A fan is added to the stack for continuous sub-slab depressurization, typically reducing radon by 90% or more.
Even a new home can test high, so a long-term test during the first heating season is recommended. We can test your new home, check a rough-in, or upgrade it to an active system. See also renovation and new build consultations.
Questions
Radon FAQ
How do I know if my home has radon?
Only a test will tell you. A long-term test of at least 3 months gives the most accurate picture. If you're buying or selling, a 72-hour real estate test gives a fast screening result.
What level is too high?
Health Canada recommends reducing radon in any home above 200 Bq/m³. Our systems aim far lower, and the Radon Reduction Guarantee covers levels below 100 Bq/m³.
How long does an install take?
Most homes are done in a day. You'll know the plan, the price and the schedule before we start.
Should I buy a home radon monitor?
Consumer monitors can be useful for keeping an eye on things, but they vary in accuracy. C-NRPP has published a consumer report on electronic radon monitors. For decisions about your health or a home sale, use a certified professional.
How can I check if a radon contractor is certified?
Use C-NRPP's certification check. Zack is listed as CRT-202962 (measurement) and CRMT-202939 (mitigation). CARST also publishes questions to ask a radon professional.
