While Colorado has a rich culture and scenic views, it is also one of the largest areas that are susceptible to radon gas. Radon gas is a colorless, odorless, and naturally occurring gas that can seep its way into a building. It can be found almost anywhere but can be toxic if levels get too high. In fact, radon gas is the second leading cause of lung cancer in the United States behind smoking tobacco. At American Radon LLC, we have made it our mission to educate Coloradans about the dangers of radon gas so they can make informed decisions on how to protect their homes and families. Additionally, we keep our services affordable so that all families can afford to make the investment in radon mitigation in Denver.

How Do I Know If My Home Has Radon Gas?

Similar to carbon monoxide, there are monitors that can be installed in your home to measure radon gas level and alert you when it becomes dangerous. However, these monitors do not have a very high accuracy rate so it’s best to perform an old-fashioned charcoal test or have a licensed radon specialist set up a continuous monitor. Radon gas occurs naturally in the soil from the breakdown of uranium so at any given time your home will have some level of radon gas. According to the Environmental Protection Agency 4.0pCi/l is considered the level for action. The conditions of the soil in Colorado put our homes at a higher risk compared to the rest of the country. The average home here in Colorado measures radon gas at 7.6pCi/L. This means that many homes would need to go through radon mitigation, which is the process used to reduce the levels of radon gas in a home.

We recommend you use a charcoal test kit to measure the radon gas as they do not require any power. While certain weather conditions can impact radon gas testing, these tests can be done during any season. Simply place the test in the lowest possible livable space in your home. This should be a place that can be easily accessed and used regularly, so not a crawl space or garage. While the test is in place, all external doors, windows, and vents need to remain closed to get the most accurate results. After 48-72 hours, you simply mail the test in a Priority Envelope to the independent, third-party lab so that it will arrive within 2-3 days. The test must make it to the lab within 10 days so mail it as soon as the test has been completed. The lab will then email the test results.

Other radon gas testing options are possible, but you should be advised on the problems with those tests. A trained home inspector can perform a computerized test to determine hour by hour radon levels and an average. Since radon gas levels can fluctuate, this is a good way to determine the average in order to gauge the danger levels. These tests are extremely expensive and need to be perfectly calibrated. Another computerized test can be purchased by private citizens to measure gas in different locations of a home, but these tests have a 50% or less accuracy rate. We would recommend performing a charcoal test to determine the reliability of the test.

You Have Many Options For Radon Mitigation in Denver

Radon Mitigation Fan used on projects in Denver Metro AreaMitigation is the process used to reduce the radon gas from your home. American Radon LLC has a variety of systems that we install based on your needs and radon levels.

These radon mitigation in Denver systems include:

  • Sub-slab depressurization system is the most common system. It uses suction from below the basement to bring the gas out through PVC piping. Depending on how the home is built we can run the exhaust pipe on the exterior, up through a garage, or even through an attic.
  • A Drain tile system is highly effective since it uses a fan attached to the perimeter or french drain system that goes around the foundation. This is an attractive option for homeowners since the entire system is located on the outside of the home rather than having a pipe in the basement then through an exterior wall.
  • If a home has a sump pump, we can tap directly into that pit to use as the draw point. This makes for the most successful type of mitigation system possible.


Radon MitigationSome homes even have an accidental mitigation system already built in. Radon gas can find its way into structural floors or floating wood floors. This type of flooring is elevated above the ground rather than sitting on top of the foundation that sits on the soil. These homes commonly have a ventilation system to control moisture. These systems also help with taking care of harmful gasses that seep into the home, including radon gas. Not only that, but they also prevent mold and mildew. If your home is equipped with such a system, there is a good chance that you already have somewhat of a radon mitigation system in place. However, a contractor may put in a radon gas fan to enhance the performance of the system. Performing a radon test is still crucial in monitoring the levels to keep your home safe, even if your home is already equipped with such protections.

How is Radon Gas Dangerous?

Given the high levels of radon gas in Colorado, it is a good decision to go through with radon mitigation in Denver should you need it. Symptoms of radon gas exposure include coughing, chest pain, recurrent respiratory infections, hoarseness, wheezing, difficulty breathing, and lung cancer. You can read more about the symptoms and dangers of radon gas exposure in our blog as well. It can be very difficult to determine if you or a family member has had significant exposure, so the only way to know for sure is to have your home tested for the levels of radon gas. Often, people do not know they are suffering from radon gas exposure until they discover a medical condition. Lung cancer is a potential risk after radon gas exposure and can develop many years later. Staying informed about the dangers of radon gas and having your home regularly tested is the only definite way to protect your family from its dangers.

While Colorado does have a higher concentration of radon gas than other parts of the country, it still exists everywhere thanks to the byproduct that naturally comes from decaying uranium. Our blog contains some important information on all the areas that have higher concentrations of radon gas. But even areas with low concentrations are not completely safe from the risk. The central part of the United States seems to have the most concentration, but even the coasts can have moderate to low concentrations. The United States is also not alone as countries such as South Korea, Canada, Ireland, and China also have areas of higher concentration of radon gas. To learn more about radon gas, there are many resources that you can consult to get the most up to date information. The Environmental Protection Agency has a Nation Radon Action Plan that aims to reduce the risk in five million homes by the year 2020. Even the American Lung Association has assisted with this plan to help communities get access to accurate testing and mitigation with the hopes of decreasing the risks of developing lung cancer.
