Breathing Should Never Be a Risk

Learn how radon mitigation protects your family's long-term health in Denver.

You spend most of your time inside your Denver home, and the air you breathe there directly affects your health. Radon is a colorless, odorless gas that seeps up through the ground and accumulates in basements and lower levels, and long-term exposure is the second leading cause of lung cancer in the United States. In Denver, where soil composition and elevation create conditions that allow radon to concentrate more easily, this risk becomes something you need to address rather than assume away.

Radon mitigation removes this gas from your home by installing a venting system that pulls it from beneath your foundation and releases it safely above the roofline. Master Mitigators designs each system to match your home's layout and radon levels, which are measured before and after installation to confirm the reduction. The work involves sealing entry points in your foundation and running a vent pipe to redirect the gas flow, so it never builds up in the rooms where you live.

What Happens When Radon Goes Unaddressed

When radon accumulates in your Denver home over months and years, it decays into radioactive particles that settle in your lungs when you breathe. These particles damage lung tissue at the cellular level, and that damage can lead to cancer even if you have never smoked. The Environmental Protection Agency estimates that radon causes approximately 21,000 lung cancer deaths in the United States each year, and about 2,900 of those deaths occur among people who have never used tobacco.

After mitigation, the radon level in your home drops to a fraction of what it was before, often below 2.0 picocuries per liter, which is well under the EPA action level of 4.0. You will not feel an immediate difference because radon has no smell or visible presence, but the long-term reduction in exposure means your household is no longer accumulating the cumulative risk that leads to lung disease decades later.

Mitigation does not require you to leave your home during installation, and the system runs continuously using a low-wattage fan that costs a few dollars per month to operate. Testing should be repeated every two years to confirm the system continues to perform as intended, especially after any foundation work or significant remodeling that could alter airflow patterns.

Questions Homeowners Ask Before Testing or Installing a System

Homeowners often want to know how radon levels are measured, how quickly mitigation works, and whether the system will need ongoing maintenance once it is installed.

How do I know if my home has elevated radon levels?
You place a test kit in the lowest occupied level of your home for at least 48 hours, then send it to a lab for analysis. Master Mitigators provides testing as part of the mitigation process and can interpret results based on your home's layout and Denver's regional averages.

What radon level is considered dangerous?
The EPA recommends mitigation for any home with a radon level at or above 4.0 picocuries per liter, but health risk increases with any exposure over time. Many homeowners in Denver choose to mitigate at lower levels, especially in homes with young children or family members who spend significant time in lower-level rooms.

How quickly does a mitigation system reduce radon levels?
Radon levels typically drop within 24 hours of system activation, and post-mitigation testing conducted after a few days confirms whether the reduction meets safety targets. The system works continuously to maintain low levels as long as it remains powered and unobstructed.

What kind of maintenance does a radon mitigation system need?
You check the system's pressure gauge monthly to confirm airflow and listen for the fan running in the attic or exterior mount. The fan may need replacement every 10 to 15 years, and any cracks or gaps in the foundation should be sealed to prevent radon from bypassing the system.

Why is radon more common in Denver compared to other areas?
Denver sits on soil and bedrock that contain uranium deposits, which decay into radon gas over time. The elevation and dry climate also mean homes are built with basements more often, and those below-grade spaces allow radon to collect before it disperses outdoors.

Master Mitigators installs systems that reduce radon exposure in Denver homes, using methods that fit your foundation type and indoor layout. If you want to schedule testing or discuss mitigation before radon becomes a long-term health concern, contact us to review your options.
