When it comes to radon testing, you have two options: using a DIY (do it yourself) testing kit or hiring a professional radon testing service. In this article, we’ll explore the pros and cons of each method, allowing you to make an informed decision about the best approach for your specific situation.


  1. Cost-effective: DIY testing kits are generally more affordable than hiring a professional service. They are easily accessible and can be purchased at local hardware stores or online.
  2. Convenience: With a DIY kit, you have the freedom to conduct the testing whenever it suits you, without relying on scheduling appointments or waiting for professionals.
  3. Quick results: Most DIY kits provide results within a short period, typically a week after being sent to the lab. This allows you to take immediate action if elevated radon levels are detected.


  1. Accuracy concerns: DIY testing kits require careful adherence to instructions to obtain accurate results. Improper usage or failure to follow instructions could lead to inaccurate readings, potentially putting you at risk.
  2. Limited expertise: Without licensed radon professional guidance, you may lack the knowledge to interpret the results correctly. This can lead to confusion or misinterpretation, potentially resulting in unnecessary concerns or delayed actions.
  3. Potential errors: DIY long-term radon test kits may be affected by environmental factors, such as humidity, improper placement, or other issues that can compromise the accuracy of the results. These errors are more likely to occur without professional guidance.
