Home Sweet Home: Radon Inspections for Denver CO Homeowners


Owning a home is a dream come true for many people, but it also comes with responsibilities. One crucial aspect of homeownership that often goes overlooked is the need for radon inspections. Radon, a naturally occurring radioactive gas, can seep into homes and buildings through cracks and gaps in the foundation, putting the occupants at risk of exposure to harmful radiation.

In Denver, Colorado, where the elevation and geological conditions contribute to higher radon levels, it’s essential for homeowners to understand the importance of regular radon inspections. This blog post aims to provide you with a comprehensive guide on everything you need to know about radon inspections in Denver, CO, including the implications of various findings and why it’s crucial to prioritize your family’s health and safety.

What is Radon?

Before we dive into the specifics of radon inspections, let’s first understand what radon is and why it’s a cause for concern. Radon is a colorless, odorless, and tasteless radioactive gas that occurs naturally in the earth’s crust. As radon decays, it releases radioactive particles that can damage lung tissue and increase the risk of lung cancer when inhaled over prolonged periods.

According to the Environmental Protection Agency (EPA), radon is the second leading cause of lung cancer in the United States, after smoking. The risk of developing lung cancer increases with higher levels of radon exposure and prolonged exposure over many years.

Why Radon Inspections are Crucial in Denver, CO

Denver’s unique geographical location and geological makeup contribute to higher radon levels in the area. The city sits at a high elevation, and the underlying soil and rock formations contain higher concentrations of uranium, a radioactive element that decays into radon gas.

Additionally, the dry climate and the way homes are constructed in Denver can also play a role in trapping radon gas inside, leading to potentially dangerous levels of exposure for homeowners and their families.

Conducting regular radon inspections is the only way to accurately detect and measure the radon levels in your Denver home. These inspections are crucial because radon exposure is often undetectable without proper testing, and the health risks associated with prolonged exposure are severe.

The Radon Inspection Process

If you’re a Denver homeowner considering a radon inspection, it’s essential to understand the process involved. Here’s a brief overview of what to expect:

Step 1: Hiring a Certified Professional

It’s highly recommended to hire a certified radon measurement professional or a qualified home inspector who specializes in radon testing. These professionals are trained and equipped with the necessary tools and expertise to conduct accurate and reliable radon inspections.

Step 2: Preparing for the Inspection

Before the inspection, you may need to follow specific guidelines provided by the professional to ensure accurate results. This may include closing windows, sealing off certain areas, and avoiding activities that could disturb the air flow in your home during the testing period.

Step 3: Conducting the Test

There are two primary methods for radon testing: short-term tests and long-term tests. Short-term tests are typically conducted over a period of 2-7 days, while long-term tests can last up to a year or more. The professional will place specialized radon detectors in strategic locations throughout your home to measure the radon levels.

Step 4: Analyzing the Results

After the testing period, the radon detectors will be collected and analyzed in a certified laboratory. The results will provide you with the average radon level in your home during the testing period, measured in picocuries per liter (pCi/L).

Understanding the Implications of Various Findings

The EPA has established guidelines for acceptable radon levels in residential buildings. Here’s what the different radon levels mean and the recommended actions to take:

Radon Levels Below 2 pCi/L

If your radon inspection reveals levels below 2 pCi/L, it is considered a safe range, and no immediate action is necessary. However, it’s still recommended to conduct regular testing every few years, as radon levels can fluctuate over time.

Radon Levels Between 2 pCi/L and 4 pCi/L

Levels between 2 pCi/L and 4 pCi/L are considered a moderate risk. In this case, the EPA recommends taking steps to mitigate the radon levels within a reasonable timeframe, typically within a year or two.

Radon Levels Above 4 pCi/L

If your radon inspection reveals levels above 4 pCi/L, it is considered a high risk, and immediate action is strongly recommended. The EPA advises homeowners to take corrective measures within a few months to reduce the radon levels in their homes.

Radon Mitigation Strategies

If your radon inspection reveals elevated levels, there are various mitigation strategies that can be implemented to reduce the radon concentration in your home. These strategies typically involve sealing cracks and gaps in the foundation, improving ventilation, and installing specialized radon mitigation systems.

Sealing Cracks and Gaps

Radon can enter your home through cracks and gaps in the foundation, walls, and floors. Identifying and sealing these entry points can help prevent radon from seeping into your living spaces.

Improving Ventilation

Proper ventilation can help dilute and remove radon gas from your home. This can be achieved by installing exhaust fans, increasing air circulation, and ensuring adequate fresh air intake.

Radon Mitigation Systems

In cases of high radon levels, you may need to install a specialized radon mitigation system. These systems typically involve creating a vacuum-like effect that draws radon gas from beneath the foundation and vents it safely outside the home.

It’s crucial to work with certified radon mitigation professionals who can assess your specific situation and recommend the most effective solution for your home.

Protecting Your Family’s Health

Radon exposure is a serious health concern, and taking proactive measures to address it is essential for protecting your family’s well-being. By conducting regular radon inspections in Denver, CO, you can stay informed about the radon levels in your home and take appropriate action if necessary.

Remember, radon is the second leading cause of lung cancer, and prolonged exposure can have severe consequences. Don’t take chances with your family’s health – prioritize radon testing and mitigation to create a safe and healthy living environment.


Homeownership comes with responsibilities, and ensuring your family’s safety and well-being should be a top priority. In Denver, Colorado, where radon levels can be elevated due to geological and environmental factors, regular radon inspections are crucial.

By understanding the importance of radon inspections, being aware of the implications of various findings, and taking proactive measures to mitigate elevated radon levels, you can protect your loved ones from the harmful effects of this invisible threat.

Don’t wait until it’s too late – schedule a radon inspection for your Denver home today and take the necessary steps to create a safe and healthy living environment for your family.
