Detect Radon Risks Early With Advanced Radon Testing

Most homes have never been tested for radon, and that's a risk no family should have to take. Radon seeps into your home silently through foundation cracks, wall cavities, building materials, gaps around service pipes, and even through your water supply. It has no odor, no color, and no taste, yet its effects on your family's health can be devastating over time. Early detection through professional radon testing is the single most important thing you can do to understand the true state of your home's indoor air quality.


At Radon Systems of Connecticut, our certified contractors have been conducting professional radon testing for over 30 years. We use advanced testing equipment that goes beyond basic home test kits, giving you precise, reliable results across every area of your home. From basements and crawlspaces to living areas and private water supplies, our indoor air testing process is thorough, methodical, and fully aligned with EPA guidelines. Short-term tests, long-term tests, continuous radon monitors, and activated charcoal absorption techniques are all part of how we build a complete picture of your home's radon levels.


What sets our testing process apart is what happens after we collect the results. We don't just hand you a number and walk away. We walk you through exactly what your results mean, where the radon is entering your home, and what your options are going forward. When families in the area search for radon testing near me, we want them to find more than just a contractor. Reach out to us today and get the clarity your family deserves about the air inside your home.

Certified Radon Testing Services for Air, Water, and Soil

Knowing your home's radon levels starts with testing every possible source and entry point. Our certified contractors use advanced equipment and EPA-approved methods to give you a precise, complete picture of the radon risks in and around your home.


  • Digital Radon Detectors: We use state-of-the-art digital radon detectors for indoor air and soil gas testing, providing real-time readings across different areas of your home. Whether it's a residential property, an apartment unit, or any living space in between, these active devices give us an immediate picture of where radon is accumulating. Every reading is carefully analyzed to ensure your results are accurate and actionable.
  • Activated Charcoal Absorption: One of the most trusted and EPA-approved short-term testing methods we rely on is activated charcoal absorption. We place charcoal canisters in key areas of your home, which passively absorb radon from the surrounding air before being sent to a certified laboratory for analysis. It's a simple, reliable, and highly effective way to get a clear snapshot of your home's radon levels.
  • Charcoal Liquid Scintillation: For homes with private wells or groundwater sources, charcoal liquid scintillation is the gold standard water radon testing method. It exposes charcoal to your water supply, absorbs radon, and measures it in a scintillation counter to detect even trace levels. Because radon in water is released into your indoor air during activities like showering and cooking, water testing is just as critical as air testing.
  • Continuous Radon Monitors: For long-term assessments that require a deeper level of detail, continuous radon monitors are our tool of choice. Unlike short-term tests, these advanced electronic devices track radon levels around the clock, recording fluctuations throughout the day and across different weather conditions. The data they produce gives us everything we need to make the most informed recommendations for your home.

Frequently Asked Questions

  • How long does a radon test take?

    The duration depends on the type of test we conduct. Short-term tests typically run between two and seven days, while long-term tests run for ninety days or more to give us a more accurate picture of your home's average radon levels.

  • How often should I test my home for radon?

    We recommend testing your home for radon at least every two years, or any time you make significant changes to your home such as renovations or adding living space below ground. You should also test immediately after purchasing a new home.

  • What is a safe radon level in a home?

    The EPA recommends taking action when indoor radon levels reach 4 pCi/L or higher. We also recommend considering action when levels fall between 2 and 4 pCi/L, as even lower levels carry some degree of health risk.

  • Is radon testing the same as natural gas testing?

    Radon and natural gas are two completely different substances that require separate testing methods. While natural gas detectors identify combustible gas leaks, radon testing measures the concentration of radioactive radon gas in your home's air and water.

  • What happens if my radon test results are high?

    If your results come back at or above the EPA's action level of 4 pCi/L, we'll walk you through exactly what the results mean and what needs to be done next. Our team is fully equipped to assess your home and recommend the most appropriate course of action for your specific situation.
