Radon Testing: A Vital Aspect of Home Inspection

Home inspections are a standard part of the buying and selling process, aiming to identify any issues or potential hazards in a property. Read here a thorough home buyers’ and sellers’ guide to radon. Radon is a colorless, odorless, and tasteless radioactive gas that can seep into buildings, including homes, from the ground. It is formed naturally when uranium in soil and rock breaks down. 

Long-term exposure to high radon levels is concerning since it increases lung cancer risk. Radon has been named by the Environmental Protection Agency (EPA) of the United States as the second-leading cause of lung cancer, right behind tobacco usage. Radon testing in Maryland is essential for detecting the presence of this dangerous gas during inspections.

Short-term and long-term radon tests are both viable options in Maryland. Radon levels can be quickly and easily assessed with a short-term test that takes about 2–7 days to complete. However, radon levels can be more accurately averaged over a longer period with long-term testing, which continues for over 90 days. Corrective measures must be taken immediately if elevated radon levels are found during the house inspection. Radon mitigation techniques can include sealing cracks and openings in the foundation, improving ventilation, and installing radon mitigation systems such as sub-slab depressurization or ventilation systems.

Here are some reasons why radon testing in Maryland is important:

Health Risk Assessment

Radon testing helps assess the potential health risk for the home’s occupants. By identifying high levels of radon, homeowners can take the necessary steps to mitigate its presence and reduce the risk of lung cancer.

Regulatory Compliance

Radon testing in Maryland may be required by law during real estate transactions. Buyers and sellers need to comply with these regulations to ensure a smooth transaction and protect both parties’ interests.

Property Value 

Knowledge of the radon levels in a home can also impact its value in the real estate market. If high levels of radon are detected, it may affect the property’s value and require mitigation measures before a sale is finalized.

Peace of Mind

For homeowners and potential buyers, radon testing provides peace of mind, knowing that they are living in or moving into a safe environment.

Radon Risk in Maryland

Residents of Maryland would be well to be aware of the radon threat, as Maryland is a high-risk state. Even properties that are directly adjacent to one another can have vastly varying radon levels.

Radon Testing Options

There are two main types of radon tests: short-term tests and long-term tests. Radon levels can be quickly assessed with a short-term test lasting a few days to a week. Radon levels can be more accurately represented over time using long-term tests lasting several months.

Radon Testing Kits 

Radon testing kits are available for purchase at hardware stores, online retailers, and some local health departments. These kits come with instructions for use and typically include a collector device that is placed on the lowest lived-in level of the home, such as the basement or first floor.

Professional Radon Testing

While DIY testing kits can be useful for initial screening, some homebuyers and sellers, as well as concerned homeowners, opt for professional radon testing services. Certified radon measurement professionals are equipped with specialized equipment and have the expertise to provide accurate results.

Radon Mitigation

If radon levels are found to be elevated, radon mitigation is recommended to reduce the concentration of radon gas indoors. The most common method used to reduce indoor radon concentrations is to construct a ventilation system near the building’s subfloor or basement.
