Radon Mitigation Edmonton: Protecting Your Home from the Ground Up

As Edmonton residents spend more time indoors during the winter, many may not be aware of the invisible hazard entering their homes through tiny cracks and openings: Radon gas. Radon is odourless, colourless, and tasteless. Radon is found in soil and rock, and the main way it gets into homes is through the soil beneath a house. Let’s discuss how the Radon Mitigation Edmonton service works and why it's one of the smartest home investments you could make for your family.

Understanding Radon Mitigation Edmonton

This is one of the main reasons Radon is an important concern in Alberta. Much of Alberta's geology naturally contains uranium, which causes Radon to be released from the soil beneath most houses. Many factors influence Radon levels, including the type of soil beneath the property, the construction and configuration of the basement foundation, existing cracks, utility penetrations, and basement air movement.

Sub-Slab Depressurization

The Radon Mitigation Edmonton system, which is the recommended and most effective method for reducing Radon gas levels in the home, is commonly called an active sub-slab depressurization system. It works by creating negative pressure beneath the foundation. The air pressure beneath the foundation slab is higher than inside your home, which draws soil gases through cracks in the foundation and floor slab. These gases, including Radon, can enter the home through cracks in the basement, wall joints, sump pumps, and floor drains. These can make your home unhealthy if they enter too rapidly.

Professional Radon Fan Installation: What to Expect

The key component of a Radon Mitigation Edmonton system is a specialized exhaust fan. It is not a standard bathroom exhaust fan. It needs to be sized properly to effectively remove Radon from your home. For example, air flows through a good, clean gravel layer much more easily than through compacted clay and silt. The Radon Mitigation Edmonton professional will measure and determine the appropriate fan size to vent your home. After your Radon Mitigation Edmonton system has been installed, you will notice a simple gauge, called a manometer, mounted on the Radon pipe that shows a differential pressure reading to verify that the system is operational.

Key Insights

• Health Canada recommends taking action when Radon levels exceed 200 Bq/m³. This is Health Canada’s current national benchmark for long-term health risks associated with Radon exposure.

• You will likely never know the levels in your home unless you test. Testing is very important because Radon fluctuates naturally with changing weather, air pressure, and season, particularly during Edmonton's winter months. Still, a long-term test will confirm your actual Radon level within your home.

• The Radon Mitigation Edmonton professionals will ensure your system properly seals any foundation cracks. They will install a properly sized fan and seal foundation openings where necessary.

Frequently Asked Questions

Is Radon a concern throughout Edmonton?

Radon can be found in homes throughout Edmonton, as it comes from natural sources in the soil and varies from house to house. Your neighbour's Radon levels are irrelevant. Even houses on the same street, built on the same foundations, could have significantly different Radon levels. 

How much does a Radon reduction system in Edmonton cost?

The price will depend on your home's construction, with newer homes typically easier to mitigate and more cost-effective. A professionally installed system that reliably protects your family’s health will be a well-priced decision. 

Can I install a system myself?

No, Radon Mitigation Edmonton systems are far more involved than installing a pipe through the basement slab. Improper installation could draw gas from the basement and draw combustion gases from appliances such as furnaces and water heaters back into your home, which could be deadly. A trained professional can design the system correctly for the specific house configuration and ensure that other air-quality and safety issues related to air balance are not created.

How often should I retest my home for Radon?

Health Canada recommends re-testing your home for Radon Mitigation Edmonton at least once every few years or after completing renovations that alter the foundation or interior space. Renovations may include changes to interior features and structural changes to the basement, as these will most certainly influence the gas levels.

What is the difference between short-term and long-term testing?

A short-term Radon Mitigation Edmonton test will confirm unusually high Radon levels. However, since Radon Mitigation Edmonton levels naturally fluctuate with changing seasons, air pressure, and barometric pressure, especially during the winter months in Edmonton, a long-term (90-day or longer) test is required to establish the average Radon Mitigation Edmonton level in your home.

What if my home is an older build with no gravel under the slab?

Older houses can certainly be mitigated, as can newer ones. An expert can provide solutions even without gravel. The expert might create new suction points if needed, or use a sub-membrane with a gravel base on top of it in a crawl space, if that exists, to pull Radon Mitigation Edmonton gas from beneath the home. 

Are there future-proofing steps I can take now?

If you are building a new home in Edmonton or planning to finish a basement, install a passive Radon rough-in in the foundation slab before the concrete is poured. If mitigation is ever required, only the fan and vent piping need to be added to complete the process! It’s a simple step during construction.

Conclusion

In conclusion, Radon is an invisible hazard that is often overlooked; it is one of the few hazards in your home you actually have control over when you decide to mitigate Radon Mitigation Edmonton. Addressing elevated Radon Mitigation Edmonton will help create a healthier indoor environment for your family. It can provide greater long-term health benefits than many other home improvement projects. Installing a Radon Mitigation Edmonton system is one of the most important home improvements you can make to help protect your family's health.
