You’ve done everything possible to make your indoor living environment healthy and safe.

But do you realize that there might still be hazardous issues lurking within your indoors, making all your efforts go to waste? No?

It’s true you might think that your indoor environment is perfect, but potential threats like radon exposure can prove you wrong.

Now, how to get rid of radon? Well, the first thing you can do is schedule a radon test.

If you want an easier solution, you can use effective ventilation strategies. These are key elements in combating radon exposure and ensuring a healthier living space.

In this blog, we’ll discuss tips that answer your question, “How to fix high radon levels?”.  

So, let’s start

Increase Natural Ventilation

When we mentioned “ventilation,” this must have come to your mind:

Opening the windows

Opening the doors

And you’re all set for fixing high radon levels…to a point.

Surprisingly, it’s true… all these are the first steps you’ll need to take. This is because this helps fresh air to circulate regularly, diluting and dispersing any accumulated radon gas.

So, we can credit this as a simple yet effective measure promoting indoor and outdoor air exchange. Eventually, this reduces the concentration of radon within your living space.

Seal Cracks and Gaps

Now, how do we take further steps? How to fix high radon levels?

Well, this is another tip you can utilize while handling the radon issue.

You can address and seal cracks and gaps in your house’s foundation, walls, and floors. This will turn out to be a critical measure that can help you in preventing radon infiltration.

There’s this thing about radon: it can enter your house through these openings, posing a potential risk. So, sealing these points is like trapping it outside and not letting it in.

This is a simple tip, but it’s very helpful as it contributes to overall energy efficiency by preventing unwanted air leakage.

Use Ventilation Systems

Ventilation is not only associated with opening windows and doors; there’s more to it. And to make the process more comprehensive, you can always use ventilation systems. In fact, that’s more of a strategic approach.

Mechanical ventilation, such as exhaust fans, is important in increasing air circulation and reducing the radon gas concentration.

With this, you can effectively draw in fresh outdoor air and expel indoor air. As a result, you can minimize the radon gas buildup.

Homeowners often wonder where to install exhaust fans to enhance ventilation. Well, these are more valuable in areas prone to radon accumulation. This includes crawl spaces and basements. With the help of ventilation systems, you can enhance the air quality and contribute to a healthier living environment.

But, there’s more to it. You can’t just raise your hands off after installing these systems. You need to regularly maintain and monitor these systems so that they keep on functioning the best, and let you rest easy.

Sub-Slab Depressurization (SSD)

This is a highly effective and the most common technique to mitigate radon gas in homes.

But what exactly is it?

This method involves installing pipes beneath the foundation or slab of your home and using a fan to create a navigational pressure zone below.

This is how you can draw away any radon gas in the soil and harmlessly vent it outside. Employing this tip, you can prevent radon’s entry into the living space.

SSD is particularly beneficial in homes with elevated radon levels, offering an efficient and reliable means of reducing exposure.

Ventilation in Basements

Did you know that radon can also accumulate in basements besides crawlspaces and attics?

No? Well, now you do.

Ensuring proper ventilation in basements is important to handle and address the risks associated with radon exposure.

And, since basements are closer to the soil, they’re more susceptible to radon infiltration.

Strategic placement of vents and maintaining good airflow in basements also reduce radon concentration.

So, if you want to create a safer and healthier living environment within your home, this is another tip you should undertake.

Regular Maintenance

You’ve installed everything to have the perfect ventilation in your house, and think you’re done and dusted?

Well, not really…

Installing ventilation systems is not the only thing you need to do. Regular maintenance is also important. In fact, it’s another measure that you must undertake.

Over time, fans, vents, and other components of ventilation systems may experience wear and tear, reducing their efficiency.

Therefore, consistent monitoring and periodic checks enable you to promptly identify and address any issues. This will also help you prevent potential failures that could compromise the effectiveness of radon mitigation efforts.

Additionally, routine maintenance ensures that sealing and other preventive measures remain intact, reducing the likelihood of radon infiltration.

Prioritizing regular maintenance is another way to sustain a proactive approach to radon mitigation – creating a living space that prioritizes the well-being and safety of its occupants.

Follow Local Guidelines

This is the best tip, honestly. You stick to local guidelines and will keep issues away from your house. As simple as that.

Adhering to local guidelines is an important aspect of implementing radon mitigation strategies. But, local regulations and recommendations regarding radon levels and mitigation techniques can vary.

Therefore, it’s important that you stay informed about the specific guidelines in your region.

By following local guidelines, you can ensure that your radon mitigation efforts align with the notified standards.

And so, you can promote a safer living environment within your house. 


In conclusion, implementing these effective ventilation tips could be a key line of defense in handling the risks associated with radon exposure.

Once you follow our outlined tips above, you can proactively address the potential threats to indoor air quality. And also create a healthier living space.

Considering the importance of radon mitigation, implementing these ventilation-focused tips not only safeguards your and your family’s health…but also reinforces the importance of health, safety, and overall indoor environmental quality within your home.
