"We had a great experience with Colin from RADONreduction. He was very knowledgeable upfront and honest. If you need radon mitigation you should definitely call this company. Very impressed!!!"-Sara Janzen, S.E. Calgary  (5-star Google review)

What others have said:

"Colin was great, very professional and above all honest, quality work ... He actually tried to talk me out of hiring him because he thought my count wasn't that high. He advised me to keep monitoring and only after I was concerned enough and had some higher readings did he come and give me a quote. He did great work and my numbers have dropped to 10 or below from 80 to 120. I would really recommend Radon Reduction." -B.D. Airdrie  (5-star Google review)


Finding out that your house has a high radon level can be scary....but it doesn't have to be. The remedy can be simple, affordable, and very effective! Results are GUARANTEED!

RADONreduction radon mitigation systems take up very little space, are located conveniently (usually in your mechanical room), use minimal electricity, and are very quiet. See system pictures and testimonials here.


Our Process, Simplified:

  • Determine ideal location (usually determined at the free, no-obligation site visit) for your radon mitigation system.

  • Perform diagnostics to determine the required size of radon-specific fan.

  • Using a specialized radon fan and piping, constantly draw the radon gas out from below your house before it can enter your breathing space.

  • To maximize effectiveness, all visible openings in your floor (gaps, cracks, holes, etc) are sealed.

  • Perform diagnostics again to verify performance.

  • Once the radon mitigation system is installed, a radon tester is deployed to verify your results.


Colin Story



Colin was the lead residential installer and estimator for Alberta's original radon company, beginning there in 2017. He has installed hundreds of successful radon mitigation systems in both residential and commercial properties in Calgary, as well as all over Alberta and B.C.. Colin has also participated in radon building code inspections, installations, and mitigations in new-construction schools for Alberta Infrastructure along with numerous other commercial clients. Colin also led the installation of thousands of alpha-track radon measurement/testing devices for a school board.


How do you fix a house with high radon?

The most effective and efficient method for mitigating/reducing radon is known as Active Sub-slab Depressurization (ASD). This is a process where the soil gas is collected below the slab (concrete basement floor) and constantly vented to the atmosphere before it can enter your home.

How much does a radon mitigation or remediation cost?

A typical ASD radon mitigation system costs between $2000-2500 on average. Since every home is unique, so is each mitigation system due to a number of factors including the routing, required system, and condition of the sub-slab material. To help you better understand our process, I offer free, no-obligation quotes

How long does it take to install a radon mitigation system?

Most radon mitigation systems can be installed in one day.

What kind of results can we expect?

I specialize in giving our customers the best results possible. I guarantee to lower the radon level in your home to under 100bq/m3, with many homes showing results below 25bq/m3!

What are the health risks of radon?

Radon is the second leading cause of lung cancer, second only to smoking.

Radon is responsible for  over 3200 deaths in Canada alone every year.

How do I know if my house has a radon problem?

The only way to know how much radon is in your home or building is to test. Radon is a colorless, odorless, tasteless, unscented gas that cannot be detected by the human senses.

How do you test for radon?

Health Canada recommends a long term alpha-track test for radon with a duration of 90-365 days. There are also digital radon detectors that show more immediate readings. Radon levels can fluctuate greatly, and it's the long-term exposure to radon that is the major health risk, so longer term testing is recommended regardless of testing device.

How do you fix a house with high radon?

The most effective and efficient method for mitigating/reducing radon is known as active sub-slab depressurization. This is a process where the soil gas is collected below the slab (concrete basement floor) and continually vented to the atmosphere before it can enter your home.

Do new houses have radon?

Yes. Any building in contact with the ground has the potential to have a radon problem. Newer homes have been made more airtight to meet energy efficiency codes. This does not allow for much natural ventilation, causing a smaller amount of radon to have a greater effect.


My house has a radon rough-in, does that mean I won't have radon?

Unfortunately not. A rough-in is designed to allow for an effective mitigation if required after testing by the home's occupant. Homes built in 2016 or later are required to be roughed in for radon mitigation.


My neighbor tested for radon, will my house be similar?

Not necessarily. There are a number of factors that affect radon levels in a house. These include the home's proximity to a uranium deposit, the geology below the house, the way the occupant ventilates, the indoor/outdoor pressure differential, how airtight the house is, openings in the slab, and a number of other factors. These are the reasons why everyone is encouraged to test for radon.

How does radon enter my home or building? 

Radon, like other gasses and liquids, takes the path of least resistance. Openings in the basement floor (slab) are the easiest entry points. Openings in the slab can include open sump pits, floor cracks, floor-to-wall joint gaps, holes under furnace, shower or tub, and floor drains.

Can I seal up all the holes/cracks/gaps to reduce my radon level?

Sealing these can help reduce radon a bit but is usually not a stand-alone solution. Since radon is an inert gas, it can makes its way in anyhow. Sealing during radon mitigation is done to improve performance by keeping the suction beneath the slab (basement floor), and to keep the room air in the room. 

What sets RADONreduction apart from other radon mitigation companies in Calgary and area?

RADONreduction is owner-operated by Colin Story who has been the lead residential radon mitigation system installer for the original radon company in Calgary. He has installed hundreds of successful radon mitigation systems in and around Calgary and southern Alberta. I am C-NRPP certified, offer guaranteed results, free no-obligation quotes, and warrantied work.

Are radon mitigation systems noisy or loud?

While there is some sound associated with most household appliances, properly installed radon mitigation systems tend to be one of the quietest. Usually quieter than a bathroom fan, often to the point that they cannot be heard until you are right beside it. I make every effort to keep our radon mitigation systems as quiet as possible.

Do I need a permit for a radon mitigations system installation?

No. Currently there are no requirements for permits in Calgary for radon mitigation system installations.

How soon will I see the results of my new radon mitigation system?
Almost immediately. I GUARANTEE IT! It takes about 48 hours for the radon that is already in the house or home to decay to the point that it's no longer detectable. After that time has lapsed, you will see a drastic reduction in the radon level in your home from your radon mitigation system. This reduction can continue to improve over the coming weeks depending on the state of the material below your basement floor (slab).

What others have said:

"RadonReduction did a very professional job at remediating radon within my home. I had independently measured high radon levels in my home and shopped around to find a contractor who could do the necessary remediation properly. I was looking for an accredited remediation company with fully insured workers and a good track record. After calling RadonReduction, I received a friendly house call from the owner, Colin. He was very clear in explaining the remediation process, including all the quality control checks needed to do the job properly. I appreciated that Colin was prompt, professional and no-pressure in his first visit to provide a detailed quote. Colin answered all my email questions promptly, including proof of liability insurance and paid-up WCB for himself and all other workers on site.

After approving the written quote, the work was scheduled for a few days later, and the work was completed fully in a day, as promised. The work was done exactly as it had been explained, and Colin took the time to show me the exact quality-control readings so that I felt comfortable that the system was operating well. He was respectful of my home, making sure to protect the floors and HVAC system.

Prior to the work being done, I purchased an electronic radon sensor, and had it running a few weeks before the remediation. Now that the remediation has been completed for over a month, I have the data to show that radon levels have dropped to a safe level starting the day after the system installation. It's really quite a nice case study of radon remediation done right. I would highly recommend this company. I have no affiliation to RadonReduction or Colin other than being a very satisfied paying client."- H.B. Scenic Acres NW Calgary (5-star Google Review)

"Colin (Radonreduction) helped me installed the mitigation system recently. I am really happy with the work.
Colin is very professional, experienced and detail oriented. He came to my house and walked me through the work required to be done, checked the entire basement thoroughly, spotted all the spots that need to be sealed and figured out the best location to put the system quickly. He is always on time, did the job nice and clean. He is very patient and nice, answered all my questions and provided great service before and after installation service.
Great service & good price, highly recommended." I.Z. Silverado, SW Calgary (5-star Google review)
