Expert Radon Testing and Inspection Services by EnvioCore

When buying a house, a radon testing typically involves testing for the presence of radon gas in the home. Radon is a radioactive gas that can be harmful if it accumulates in high levels in an enclosed space, such as a home. It is odorless, colorless, and tasteless, making it difficult to detect without specialized equipment.

Radon Inspections

A radon inspection involves hiring a professional radon tester or radon testing company to perform the inspection. The inspector will use specialized equipment to measure the levels of radon in the home. The most common type of radon testing is a passive test, which involves placing a device, such as a charcoal canister, in the lowest livable area of the home for a certain period of time (usually 2-7 days) to collect air samples.

If the test results show that the radon levels in the home are above the recommended safe levels (4.0 pCi/L), further testing may be necessary to determine the source and extent of the radon problem. In some cases, remediation measures, such as installing a radon mitigation system, may be necessary to reduce the radon levels to a safe level.

It’s important to note that radon inspections are not typically included in a standard home inspection and may need to be scheduled separately. However, some home inspectors may offer radon testing as an add-on service. It’s also important to check with your state or local regulations regarding radon testing and mitigation requirements for home sales

A radon testing is typically required when purchasing a house, and is highly recommended. Radon is a naturally occurring radioactive gas that can be harmful to human health, especially the human lungs. It is estimated to cause thousands of deaths from lung cancer each year. Radon can seep into homes through cracks in the foundation, walls, and floors, and it can accumulate to dangerous levels.

Many states and localities require that new homes be built with radon-resistant features, and some states require radon testing for real estate transactions. However, in most cases, radon testing is not required by law when purchasing a home.

Even if radon testing is not required, it’s a good idea to have a radon inspection performed as part of the overall home inspection process. A radon inspection is relatively inexpensive and can provide valuable information about the safety of the home. If high levels of radon are found, it may be necessary to install a radon mitigation system to reduce the radon levels and ensure the safety of the occupants.

In summary, while a radon inspection is not typically required when purchasing a house, it is highly recommended to ensure the safety of the home’s occupants.

What if the Levels of Radon are High?

If the radon levels in a home are found to be above 4.0 picocuries per liter (pCi/L) during a radon inspection, it is important to take action to reduce the levels of radon to protect the health of the home’s occupants.

The first step is to confirm the radon levels with a follow-up radon test. The follow-up test can help determine if the initial test was accurate and provide more information about the extent of the radon problem.

If the follow-up test confirms that the radon levels are above the recommended safe level, the next step is to mitigate the problem. Radon mitigation involves installing a system that vents the radon gas from the home to the outside. A certified radon mitigation contractor can evaluate the home and recommend the appropriate type of mitigation system based on the home’s specific needs and construction.

Radon mitigation systems typically involve the installation of pipes and a fan in the basement or crawl space of the home to draw the radon gas out and vent it to the outside. The cost of radon mitigation can vary depending on the size of the home, the type of system required, and the geographic location.

It’s important to note that radon mitigation systems are effective in reducing radon levels, and they can also help improve indoor air quality by reducing moisture levels in the home. It’s recommended to have the radon levels retested after the mitigation system has been installed to confirm that the levels have been reduced to a safe level.

Radon Testing FAQs

What is radon and why is it a concern in homes?

Radon is a naturally occurring radioactive gas that can seep into homes from the ground. It is the second leading cause of lung cancer, after smoking, and is a serious health concern.

How can I tell if my home has high levels of radon?

The only way to know if your home has high levels of radon is to test for it. You can purchase a do-it-yourself radon testing kit or hire a professional to conduct the test.

How often should I test for radon in my home?

The EPA recommends testing for radon every two years, especially if you have made structural changes to your home or if you have never tested before.

What should I do if my home has high levels of radon

If your home has high levels of radon, you should take steps to mitigate the problem. This may involve sealing cracks in the foundation or installing a radon mitigation system, which vents radon gas out of your home.

How much does radon testing cost?

The cost of radon testing can vary depending on the method you choose and whether you hire a professional. A do-it-yourself kit may cost as little as $10, while professional testing can range from $100 to $300.

Can radon be reduced to safe levels in a home?

Yes, radon levels can be reduced to safe levels with proper mitigation techniques. It’s important to address the problem as soon as possible to protect your health and the health of your family.
