Why are radon tests important prior to home renovations?

Radon tests are crucial prior to home renovations primarily to determine existing radon levels before any changes are made. Understanding the baseline radon concentration is essential as renovations can inadvertently affect the home’s air flow and structure, which may alter radon levels. For instance, sealing spaces or modifying ventilation can trap radon gas indoors, leading to an increase in concentration.

By establishing the initial radon levels, homeowners can evaluate the effectiveness of any mitigation efforts after renovations are completed and ensure that their living environment remains safe. This proactive approach can help address radon exposure risks before they are exacerbated by construction activities, especially in areas known for elevated radon levels.
