What is Radon Mitigation System- A Comprehensive Guide

## Understanding Radon Mitigation Systems

As you go about your everyday household chores, you may find spots of mold, smell odors, and see paint chipping – all signs that indicate issues within your home. Just like our bodies, our homes age and experience routine wear and tear. But some areas within our homes are afflicted by dangerous issues undetectable by the human senses. Radon, an odorless, colorless, and tasteless radioactive gas, is the second leading cause of lung cancer to smoking, according to the [Environmental Protection Agency (EPA)](https://www.epa.gov/radon/health-risk-radon#:~:text=Radon%20is%20the%20number%20one,people%20who%20have%20never%20smoked.). Radon is present in roughly 1 in 15 homes and can seep in through cracks in the foundation, gaps in construction joints, and other entry points, accumulating to dangerous levels over time. Radon mitigation systems are crucial for safeguarding your health by preventing radon infiltration and effectively venting the gas outdoors. 

## How Radon Mitigation Systems Work
![How Radon Mitigation Systems Work](https://d2nnm6ppct4rc3.cloudfront.net/How_Radon_Mitigation_Systems_Work_15e9e9e394.png)

[Radon mitigation systems](https://wini.com/articles/radon-symptoms-exposure-health-risk-and-prevention/) work by creating a negative pressure zone and venting radon gas outdoors, freeing your family from the harmful effects of prolonged exposure. To create the negative pressure zone, a vent pipe, known as a suction point, is installed in the lowest level of the home, creating an effective buffer for entry. A radon-specific fan is then installed to create suction, drawing radon gas from the soil beneath the home before it can infiltrate the living space above. When the radon gas rises, it is channeled through the vent pipe up to the roofline, where it is safely expelled outside. 

In some cases, [radon mitigation systems](https://www.health.state.mn.us/communities/environment/air/radon/mitigationsystem.html) may have continuous monitoring features to track radon levels and system performance.  

## 5 Key Components of Radon Mitigation Systems

1. Suction Point: Located beneath the building's foundation, the suction point is where radon gas is drawn out of the soil. 

2. Radon-Specific Fan: Creating negative pressure within the system, this fan allows radon to be properly vented from the home. 

3. PVC Piping: PVC (polyvinyl chloride) piping transports radon gas from the suction point to the radon-specific fan so it can be released outside. 

4. Manometer: A manometer is used to measure and monitor the pressure differentials within the radon mitigation system, ensuring proper functioning and performance. 

5. Ventilation Stack: The ventilation stack is the section of the vent pipe that expels radon from the roof. 

## Types of Radon Mitigation Systems

There are a number of ways you can [mitigate radon](https://wini.com/articles/radon-mitigation-so-you-have-radon-now-what/) in your home, including crawl space ventilation and proactive measures. Crawl space ventilation is simple and effective, ventilating the crawl space beneath the home to reduce high radon levels. Homes with elevated crawl spaces or dirt floors as the foundation could benefit from this mitigation method.  

Alternative approaches to radon mitigation include sealing cracks in the foundation, caulking gaps around utility penetrations, and installing sump sealants to prevent radon from coming in through floor drains. While these sealing techniques alone may not be as effective as active mitigation systems, they can complement other mitigation measures to further reduce the radon levels inside your home. 

### What is the Most Effective Radon Mitigation Method? 
![Sub-slab depressurization (SSD) - Radon Mitigation Method](https://d2nnm6ppct4rc3.cloudfront.net/sub_slab_depressurization_SSD_e5cf0a04ab.png)

The most effective radon mitigation method depends on various factors, including the home’s construction, foundation type, soil characteristics, and local climate. However, sub-[slab depressurization (SSD)](https://www.pmenv.com/articles/how-sub-slab-depressurization-system-installed-infographic/) is generally considered the most effective approach for reducing indoor radon levels. SSD systems create negative pressure zones beneath the home's foundation, intercepting radon before it can infiltrate the indoor environment. This is ideal for homes with concrete slab-on-grade or basement foundations, and they offer consistent and reliable radon reduction, making them a preferred choice for many homeowners. 

### Choosing the Right Mitigation System 

Selecting the appropriate radon mitigation system is essential in effectively reducing indoor radon levels and ensuring a safe and [healthy indoor environment](https://wini.com/articles/how-to-make-your-home-healthier/) for you and your family. To choose the right mitigation system for your home, you’ll need to consider many factors including your home’s construction and foundation type, the type of soil beneath your home, and the local climate.  

The [type of foundation](https://wini.com/articles/foundation-types/) and construction of the building will influence the suitability of various mitigation methods. For example, sub-slab depressurization is ideal for homes with concrete slab-on-grade or basement foundations, while crawl space ventilation may be more suitable for homes with elevated crawl spaces. Soil looseness and radon concentration levels in the surrounding soil can also impact the effectiveness of mitigation systems. [High radon levels](https://www.epa.gov/radon/what-epas-action-level-radon-and-what-does-it-mean#:~:text=EPA%20recommends%20homes%20be%20fixed,L%20and%204%20pCi%2FL.) in the soil may require more aggressive measures to reduce your indoor radon concentration to a safe level. Climate conditions, such as temperature and humidity, also affect the performance of radon mitigation systems, so consider your area’s freeze-thaw cycles and moisture levels.  

 
![Radon Test by WIN Home Inspection](https://d2nnm6ppct4rc3.cloudfront.net/Radon_Test_by_WIN_Home_Inspection_213ad8c412.png)
As a WIN home inspector and trainer, I've seen firsthand the detrimental effects that radon can have on both homes and occupants. Radon is a silent threat, seeping in through cracks in the foundation and accumulating to dangerous levels over time.  

Implementing a radon mitigation system can drastically improve the safety and livability of a home. Radon mitigation systems effectively vent radon gas out of the home, significantly reducing the risk of long-term health issues associated with exposure.  

Homeowners who have invested in radon mitigation systems not only enjoy improved [indoor air quality](https://wini.com/articles/how-to-test-indoor-air-quality-to-breathe-safely/) but also have the relief of knowing their loved ones are protected. As an advocate for my community’s well-being, I can't stress enough the importance of addressing radon and implementing mitigation measures to prevent this radioactive toxin from breaching our health and safety.

Does Cold Weather Affect Radon Levels in the Home

## Introduction 

During home inspections, we often run into clients without proper radon awareness. This cancer-causing agent seeps into our homes without warning. And with colder temperatures, radon's soil concentration only increases. In this inclusive guide, we will learn the dangers of high radon levels and the importance of regular testing. 

## Understanding Radon and Its Dangers
![Understanding radon and its dangers](https://d2nnm6ppct4rc3.cloudfront.net/Understanding_radon_and_its_dangers_19a13e6b39.jpg)

Imagine you just moved into a beautiful new home, nestled in the perfect neighborhood. But while you're enjoying cozy evenings in your home by the fireplace, there’s an invisible threat lurking in the background - radon! This radioactive gas is indistinguishable by human senses as you can’t see, smell or taste it, making professional testing the only known detection method. 

Frequent [radon testing](https://wini.com/articles/what-is-radon-guide-to-radon-and-radon-testing/) is not just a cautionary measure; it's a necessity. Virtually every home in the U.S. has some level of radon, but prolonged exposure to elevated radon levels can lead to [serious health issues](https://www.epa.gov/radon/health-risk-radon) ranging from asthma to lung cancer. This gas can seep into any home, regardless of its location or age, through [cracks in its foundation](https://wini.com/articles/foundation-types/). We’ve even encountered many instances of elevated radon levels in neighborhoods that have no historical evidence of radon detection in the past. To make matters worse, cold air risks dangerously high radon levels.

## Understanding Dangerous Radon Levels and EPA Guidelines 
![Radon Levels and EPA Guidelines](https://d2nnm6ppct4rc3.cloudfront.net/Radon_Levels_and_EPA_Guidelines_f6a6944b09.jpg)
Homeowners like yourself should understand the radon detection process. We measure radon levels in picocuries per liter of air (pCi/L). The Environmental Protection Agency (EPA) has established [guidelines](https://www.epa.gov/radon/what-epas-action-level-radon-and-what-does-it-mean) to help you identify when radon levels are hazardous. 

- 4 pCi/L and Below: This is the recommended action level. While no level of radon is entirely safe, levels at or below 4 pCi/L are considered acceptable, and mitigation may not be immediately necessary. 
- Between 4 pCi/L and 8 pCi/L: In this range, the EPA recommends taking action to reduce radon levels in your home. Consider mitigation measures to safeguard your family's health. 
- Above 8 pCi/L: Radon levels at or above 8 pCi/L are considered dangerous. Take immediate action to reduce these levels as long-term exposure can have severe health consequences. 

## Health Risks Associated with High Radon Levels 

Now that we understand the EPA guidelines for high-level radon detection, let's delve into the known health risks. Radon’s adverse side effects should prompt you and other homeowners to test once every 1 to 3 years. 

- Lung Cancer: Prolonged exposure to high levels of radon significantly increases the risk of developing lung cancer. In fact, radon is the second leading cause of lung cancer in the U.S. behind smoking, responsible for tens of thousands of deaths each year.  

- Respiratory Problems: Radon can irritate the respiratory system, leading to persistent symptoms such as coughing, wheezing and shortness of breath, particularly in individuals with pre-existing respiratory conditions. 

- Cardiovascular Issues: Some studies suggest that radon exposure may also be linked to cardiovascular problems, although more research is needed for confirmation. 

- Children's Health: Children exposed to elevated radon levels may face an increased risk of developing respiratory infections, and their lung development may be impaired. 

- Increased Risk for Smokers: For individuals who smoke and are exposed to high radon levels, the risk of lung cancer is even greater. The combination of smoking and radon exposure is particularly dangerous. 

## How Does Radon Enter My Home? 

As home inspectors, we get asked this question a lot. Radon can enter homes through various ways. 

### 1. Soil
The most common source of radon in homes is the soil beneath the foundation. As uranium in the soil decays, it releases radon gas, which can infiltrate your home through cracks and openings in the foundation. Granitic, loose and dry soil are more prone to radon gathering and release. 

### 2. Well Water
If your home relies on well water, radon can be present in the water supply. Radon can be released into the indoor air when water is used for activities such as showering, cooking, or laundry. [WIN’s Radon-In-Water Test](https://wini.com/services/radon-in-water-test/) takes the Water Quality Test to a new level by specifically searching for this carcinogen.  

### 3. Building Materials
In some cases, building materials used in your home's construction, such as concrete and granite, may contain traces of uranium or radium, contributing to heightened indoor radon levels. [WIN Home Inspection](https://wini.com/) offers a [One-Year Warranty Inspection](https://wini.com/services/one-year-warranty-inspection/) for buyers looking to ensure no hazards were left behind by your contractors. A Radon Test pairs perfectly with your One-Year Warranty Inspection.  

## Does Cold Weather Affect Radon Levels in the Home? 

One of the common questions homeowners like yourself have is whether cold weather can impact radon levels within their homes. Much like cold weather affects our HVAC, air quality, and energy efficiency, it affects radon levels.  

## Why Radon Levels Are Higher in Winter 

During the winter months, radon levels can be higher in homes for several reasons: 

### 1. Soil Conditions
[Cold weather](https://wini.com/articles/top-7-tasks-for-homeowners-to-complete-before-winter/) freezes the ground beneath your home, reducing the ability of radon gas to escape from the soil. As a result, the gas may accumulate and seep into your home more easily with small changes in air pressure and temperatures. For instance, melting ice allows trapped radon to escape in bulk and enter your home all at once. Increased atmospheric pressure leads to increased air pressure within soil, forcing radon through your home’s foundation.  

### 2. Ventilation Differences
In winter, homes are sealed tightly to [conserve energy](https://wini.com/articles/energy-saving-tips-to-reduce-your-electric-bill/) and keep the cold air out. While this is excellent for energy efficiency, it can also trap radon gas indoors, leading to higher concentrations. 

### 3. Indoor Activities
In colder weather, people tend to spend more time indoors, increasing your exposure to elevated radon levels. 

### 4. Stack Effect
The stack effect occurs when warm air rises due to its light density and escapes through the upper levels of your home. A pressure vacuum forms inside, pulling radon gas into your living space. 

### 5. Lower Humidity
Cold air typically has lower humidity levels, which can also influence radon levels. Lower humidity can make the air within your home denser, causing radon gas to increase in concentration. 

## When Are Radon Levels Highest? 

Radon levels can vary throughout the day and year, but they often peak during the winter months. Factors that influence peak radon levels include: 

- Seasonal Changes: Winter and early spring tend to see higher radon levels due to the frozen ground and reduced ventilation. Melting ice brings radon into the home through cracks in the foundation in bulk. 

- Time of Day: Radon levels often rise during the evening and early morning when indoor activities are at their peak. 

- Home Characteristics: The construction and ventilation of your home, as well as its location, can affect radon levels. Older homes with poor ventilation may be more susceptible to radon buildup and some areas of the U.S. are known for higher levels of radon.  

To ensure your family's safety, it's essential to conduct regular radon testing, especially during the colder months. By being proactive, you can prevent radon’s health risks from reducing your and your family’s quality of life.  

## Causes of Radon Level Spikes 

While radon is a constant presence in our homes, its levels can fluctuate and dangerously spike. Understanding what causes these spikes is essential for homeowners. Here are some key factors: 

- Soil Composition: The type of soil beneath your home can influence radon levels. Homes built on soil with higher levels of uranium or radium are more likely to experience spikes. Granitic soil most commonly contains radon. 

- Cracks and Openings: Radon can enter your home through cracks in the foundation, gaps around pipes and other openings. The size and number of these entry points can affect radon levels. 

- Foundation Type: The construction of your home's foundation can also play a role. Basements and crawl spaces tend to have higher radon levels than homes built directly on a slab. 

- Well Water: If your home has a well, radon in its water supply can elevate indoor radon levels. 

- Ventilation: Poor ventilation allows radon to accumulate indoors. Insufficient airflow in basements and closed-off rooms can lead to higher radon levels. 

## Recognizing the Signs of Elevated Radon Levels 

[Radon Testing](https://wini.com/services/radon-test/) is the only way to know with confidence that your home is safe from radon. With the help of your trusted WIN home inspector, however, you can stay ahead of radon before it adversely affects your and your family’s health. WIN’s Home Inspection’s Radon Test uses state-of-the-art technology to identify radon levels in your home. With most radon tests, we’ll continuously monitor radon levels over the course of two days; however, we abide by state and local regulations, so your radon test may differ.  

**While you should be testing every 1 to 3 years**, keep an eye out for these signs as they could indicate elevated radon levels in your home: 

- Respiratory Symptoms: Persistent coughing, wheezing, and shortness of breath, especially when indoors, with no cause or reason. 

- Frequent Respiratory Infections: If you or your family members experience a higher frequency of respiratory infections. 

- Unexplained Fatigue: Feeling unusually tired without an apparent cause. 

## Radon Prevention Tips 

To prevent radon spikes and maintain healthy indoor air quality, consider following these tips:

**2. Why Is Radon Higher in Winter?**
Radon levels tend to be higher in winter due to factors like frozen ground, reduced ventilation, increased indoor activities, and the stack effect, all of which contribute to radon buildup. 

**3. When Are Radon Levels Highest?**
Radon levels can vary throughout the day and year, but they often peak during the winter months when homes are sealed tightly, and ventilation is reduced. Other factors like seasonal changes and home characteristics also play a role in peak radon levels.

Does Cold Weather Affect Radon Levels in the Home?

During home inspections, we often run into clients without proper radon awareness. In this inclusive guide, we will learn the dangers of high radon levels and the importance of regular testing.

What is Radon? Guide to Radon and Radon Test

If you are buying or selling a home or you’ve never had your home tested for radon, getting a professional Radon Test can protect you and your family from serious health issues. Radon is a naturally occurring, radioactive gas, and because of its nature, it’s in virtually every home in the U.S. and nearly impossible to detect without the proper equipment.

While most homes in the U.S. have some level of radon, nearly 1 in every 15 homes, that’s at least one per neighborhood on average, have higher than safe levels of radon. Prolonged exposure can have devasting health effects including aggravated asthma symptoms, increased respiratory infections, and lung cancer.  

Radon is the leading cause of lung cancer among nonsmokers, and the second leading cause of all lung cancers cases. Unfortunately, radon is not predictable, but it is preventable! The U.S. [Environmental Protection Agency (EPA)](https://www.epa.gov/radon/how-often-should-i-testretest-my-home-radon) recommends you test your home for radon at least once every two years.

Just because your home was safe from radon in the past, doesn’t mean it’s safe from radon now. Changing temperatures, climate, and [weather can all affect radon levels](https://wini.com/articles/does-cold-weather-affect-radon-levels-in-the-home/).  

In this article, we’ll talk all about radon, including what it is, what to expect with a Radon Test, and how to reduce high levels of this hazardous gas. Let’s dive in!

## What is Radon?
![What is Radon](https://d2nnm6ppct4rc3.cloudfront.net/What_is_Radon_29615c1b7b.png)

Radon is a colorless, odorless gas formed by the decay of uranium in soil and rock. Radon typically enters the home by seeping through cracks in your home’s foundation and building materials, like wood and sheetrock. Over time, radon gas can build up, leading to poor indoor [air quality](https://wini.com/articles/indoor-air-quality-importance-implications-and-remediation/) and health issues for you and your loved ones.

## When to Conduct a Radon Test

All homeowners should test their homes for radon. Radon has been found in all 50 states and in all types of houses, so it is impossible to predict which homes are safe without conducting a proper test. Radon levels can also change over time, making frequent testing important. Homeowners should consider testing their homes for radon if they haven’t tested in more than two years, if anyone in the household is experiencing unexplained respiratory issues, or if there have been significant changes in the soil, weather, or landscape.  

Home sellers should also test their home for radon when [preparing to sell](https://wini.com/articles/pre-listing-inspection-for-sellers-why-get-a-pre-listing-home-inspection/). This helps home sellers take proactive steps to mitigate radon and avoid unexpected delays during the home selling process. Likewise, home buyers should add a professional radon test as part of their home inspection. If the test results show elevated levels of radon, you as the buyer have options to negotiate for radon mitigation or ask the seller to adjust the sales price to cover mitigation costs before closing the deal on your new home. 

As a professional home inspector, I’ve conducted many Radon Tests over the years, and I’ve seen high radon levels found in homes of all shapes, sizes, and ages. From 100-year-old Victorian homes to brand new construction homes, radon is prevalent. I urge every home buyer and homeowner to have their home for tested for radon if they haven’t done so already.

## What Homes Are at a Higher Risk for Radon? 
![What Homes Are at a Higher Risk for Radon](https://d2nnm6ppct4rc3.cloudfront.net/What_Homes_Are_at_a_Higher_Risk_for_Radon_66cdcf98ac.png)

While every homeowner should test their home for radon, here are a few factors that may indicate higher risk:

- Location: Some regions are known to have higher radon levels than others. The Appalachian Mountains and Upper Midwest have higher levels, while the Southeast has lower levels. Keep in mind that low risk areas do not guarantee that your house is safe from potentially elevated radon levels.

- Foundation Type: Older homes with dirt floors in the basement have nothing to slow the rise of radon gas from the soil. Exposed crawl spaces also allow radon to rise into living areas unchecked. 

- Foundation Damage: Radon can seep through concrete, but foundation slabs and walls with cracks make it easier for radon gas to seep in at a faster rate. 

- Other Construction Gaps: Any gap in the structure can allow radon to enter the home. Common examples are gaps around pipes and wires, construction joints where walls and floors meet, and open sump pumps. 

- Well Water: Groundwater can also contain radon. If you rely on a well, have your [water quality tested](https://wini.com/articles/water-quality-testing-guide-cost-checklist-and-more/) regularly for contaminants, including [radon](https://www.cdc.gov/healthywater/drinking/private/wells/disease/radon.html). 

## How to Test Your Home for Radon 

To get the most accurate results and gain peace of mind, have your home tested by a professional. A qualified inspector knows exactly where to place the radon device to get the best results and follow local compliance. They can also inspect your home to help identify areas where radon could be seeping in.

### Short-term Radon Test Kit
![Short-term Radon Test Kit](https://d2nnm6ppct4rc3.cloudfront.net/Short_term_Radon_Test_Kit_41b74e1e9e.png)

While we recommend hiring a professional to conduct your Radon Test, you can buy a Short-Term DIY Radon Test kit at a local hardware store or home improvement center. While these home radon test kits may seem like a more cost-effective option, they are not as accurate as radon tests conducted by professionals. Not only is professional testing equipment better, but placing the equipment in the home appropriately is also important. Each home is uniquely designed, and local and state regulations have set standards on how to effectively place the equipment to ensure accurate results. When conducting a DIY test, you run the risk of a faulty test and don’t have assistance reading the results or determining next steps for mitigation.  

### Continuous Radon Tests 
![Continuous Radon Tests](https://d2nnm6ppct4rc3.cloudfront.net/Continuous_Radon_Tests_567386c2e4.png)

Continuous radon tests are conducted using monitors that run continuously to measure the concentration of radon over an extended period of time, typically 48 hours. Professional inspectors will place the device(s) in the home strategically to capture accurate results. The device will monitor radon levels in the home over two days, attempting to reduce or eliminate interference or “measurement noise” that can result in false results. After two days, the device is collected, and a report is drawn up with the results. It’s important that during these two days, the monitor is not touched or tampered with.  

Home inspection companies, like WIN Home Inspection, who offer one-stop shopping can conduct both air and [water radon tests](https://wini.com/articles/radon-in-water/) for you along with a [full home inspection](https://wini.com/articles/residential-home-inspection-everything-you-need-to-know/) and other essential services. This provides you with a complete picture of your home. 

### Long-Term Radon Tests 
![Long-term Radon Test Kit](https://d2nnm6ppct4rc3.cloudfront.net/Long_term_Radon_Test_Kit_62b1110973.png)

Long-term tests tend to be more accurate than short-term ones because they use alpha particle tracking to determine radon levels. These tests collect radon gas for three months to a year. This test is mostly recommended for homes located in high-risk regions. 

A professional continuous radon test offers the benefits of quick results while still providing a high degree of accuracy. This test is a great option for homeowners, buyers and sellers concerned about the radon levels in their home and want to avoid potential long-term exposure.

## Understanding Your Radon Test Results
![Understanding Your Radon Test Results](https://d2nnm6ppct4rc3.cloudfront.net/Understanding_Your_Radon_Test_Results_59bc4d9cde.png)

Radon is measured in picoCuries per liter (pCi/L). Though no level of radon is considered safe, the EPA has established guidelines for acceptable levels. If your test results show radon levels at  

- 4 pCi/L or higher, you should take radon abatement and mitigation measures to reduce the amount of gas in your home and lower your risk for radon-related lung cancer. 

- Between 2 and 4 pCi/L, action may not be immediately necessary, but you should still consider taking some precautionary steps to lower the radon levels. 

It’s important to take your radon results seriously and act quickly. While getting test results showing high levels of radon can seem scary, I assure you that it can be easily mitigated. You can have a radon mitigation system installed, which will help reduce the amount of radon in your home. You can also help prevent radon from entering your home by sealing cracks and gaps in the foundation. Finally, test for radon often to ensure your home remains a safe haven for your family.

## Radon Mitigation 

If radon is identified in your home, you should take immediate steps to reduce radon levels. On average, radon mitigation costs can range between $800 and $1,500, depending on your home’s floorplan, size, foundation type, construction quality, and location. A radon mitigation system is the best way to reduce radon levels in your home because it uses pipes and fans to remove the gas from beneath the foundation before it can enter your home.

### How to Reduce Radon and When to Take Action 

If your home has radon levels above 4 pCi/L, you need to take action against radon. Here’s a few steps you can take to mitigate and reduce radon levels in your home: 

- Seal cracks in walls and floors using plaster or caulk 
- Install a radon mitigation system  
- Increase air flow by opening windows and using fans to help circulate the air 
- Install a water filtration system that removes radon from water

## Radon Risk Factors and Health Issues
![Radon Risk Factors and Health Issues](https://d2nnm6ppct4rc3.cloudfront.net/Radon_Risk_Factors_and_Health_Issues_1fcb816d81.png)

Radon is a known carcinogen, or substance that can cause cancer with prolonged exposure. In fact, the EPA has found that radon causes [between 15,000 and 22,000 lung cancer deaths each year](https://www.cancer.gov/about-cancer/causes-prevention/risk/substances/radon/radon-fact-sheet) in the U.S. Moreover, radon is present in roughly 20%-30% of asthma cases triggered by environmental factors at home.  

Because it can take years for [radon symptoms](https://wini.com/articles/radon-symptoms-exposure-health-risk-and-prevention/) to come to light, detecting radon early can protect you and your family from developing devastating health issues in the future. 

Radon is a serious issue in many homes and can lead to major health problems. If you are unsure about the radon levels in your home, getting a Radon Test by a professional can help protect you and your family from its deadly consequences. 

At WIN, we’re here to not only help you protect your most valuable investment, but the well-being of you and your family. I’ve heard almost every excuse in the book about why someone doesn’t want to get a Radon Test – it’s expensive, it’s inconvenient, my home’s fine... - but I’m here to tell you that knowledge is power and knowing if your home has radon is worth it. I’ve been fortunate enough to also hear some amazing, and frankly, life-saving stories of clients who had their homes tested for radon and have been so thankful that they were able to take action and protect their families.

## Frequently Asked Questions

### Where does radon come from? 

Radon is naturally occurring and releases as a gas when the uranium in soil and rock decays.  

### Should I buy a house with a radon mitigation system? 

A radon mitigation system is an effective way to immediately reduce and keep radon levels at bay. If a home already has a radon mitigation system installed, it could mean that the home has previously had a high level of radon or is in an area where radon is more concentrated. Either way, having this system installed is a great way to protect you and your family against future radon exposure.  

### How can I get rid of radon? 

To get rid of radon, you should seal cracks and gaps with caulk, ventilate the home, and install a radon mitigation system.  

### How much is a radon mitigation system? 

On average, radon mitigation systems can cost anywhere from $800 to $1,500, but it depends on the home’s floor plan, size, and other factors.  

### What are considered safe radon levels? 

While all levels of radon pose a risk, action should be taken if levels read higher than 4 pCi/L. 

### How long does a Radon Test take? 

The time it takes to complete a Radon Test depends on the type of equipment used and the size of the house, however, the most popular Radon Test uses a continuous radon monitor, which runs for two days.  

### How can radon exposure affect children’s health? 

Exposure to radon can significantly harm children’s lung health, as they are more sensitive, causing developmental issues, asthma, and respiratory infections.  

### Is radon testing really necessary? 

Yes. If your home has never been tested for radon, any members of your family are experiencing unexplained respiratory issues, or conditions related to the soil or climate have changed significantly, you should have your home tested for radon right away. 

### How much does a Radon Test cost? 

The cost of a Radon Test varies by location, the type of test you need, and the size of your home, among other factors, but typically ranges between $150-$300 on average.  

### How accurate are two-day Radon Tests? 

Two-day Radon Tests are reliable and give accurate radon level readings as long as the device was not tampered with.
