What Every Home Buyer Should Know About Radon Gas

Radon Gas – What You Should Know

If you are buying a home – or even if you aren’t – you might have heard of radon gas and that it is a possible hazard. What should you know about radon?

What Is Radon?

Radon is a colorless and odorless gas that is radioactive. It is naturally occurring and, under normal conditions, very easy to inhale. Radon has a very short half-life (3.8 days at the most) but is still common enough to be a health hazard in some areas. The EPA considers radon to be a significant hazard to human health.

How Dangerous Is Radon?

Radon contributes to radiation exposure and is almost as high a cause of lung cancer as cigarette smoking (causing 21,000 deaths from lung cancer in the United States). The vast majority of those also smoke, and the combination gives the highest risk, but radon is the number one cause among non-smokers. Radon may also slightly increase one’s risk of other cancers. Radon exposure has no immediate symptoms and the effects may take years to show up.

How Much Radon Is There In the Ann Arbor/Livonia/Plymouth Area?

Wayne County is a relatively low radon area, with 61% of homes tested showing levels of under 2 pCi/L. However, there are some homes with considerably higher levels and about 17% have levels that would be considered hazardous. Therefore, it is very important to check the radon levels in your home or a home you are considering buying.

Should I Get A Radon Test?

Yes. A radon test is the only way to know a specific home’s levels for sure. If you’re buying a home, ask your home inspector for a radon test.. Testing is inexpensive, consider repeating the test. It may be worth it as buying a home with elevated radon levels but no mitigation in place is both dangerous and expensive. The Michigan Indoor Radon Program has more information on testing and other resources.

We don’t recommend using a DIY home radon test kit, as there are many variables that can skew results. Professionals that do this everyday know how to set up the machines and perform a test to get accurate results.

If the home already has radon mitigation systems in place you should still consider getting a test to make sure they are working effectively.

Mitigating Radon Gas

Radon mitigation generally involves reducing the amount of radon that builds up within the home. Radon leaks out of the ground and would normally simply drift harmlessly up into the atmosphere in very low concentrations. When it enters your home, however, it is caught by the roof (especially if you have the kind of insulation needed for (Michigan winters) and builds up. Radon mitigation takes several forms. One of the most effective is active soil depressurization. This is a system which pulls gas that comes out of the soil out from under your house and exhausts it away from the building or through a vent on the roof.

If your home does not have a crawlspace. Then a gas permeable layer under a plastic sheet can also be used to prevent radon gas coming into the home. It is recommend that below-grade openings be properly sealed and caulked. Some new homes are constructed with radon-resistant materials and systems already in place. If you are buying a new home then ask what the builder is doing to mitigate radon.

Radon is a very real health risk. Fortunately, it is also easy to deal with. However, you may not want to have to deal with the inconvenience and expense of installing radon mitigation systems in your new home. As a result, it is desirable to test radon levels before signing any kind of contract on a new house. Especially in areas where radon levels are historically high. If you want a professional radon test done on your new (or existing) home, then Contact Trademark Home Inspection for details. We will also be able to recommend appropriate mitigation if needed.

  1. This is standard practice, if there is no radon issue, there is no need for extractors, as the tests show there is a radon buildup, extractors are added, This is all standard.

  2. This is some really good information about radon mitigation. I liked that you pointed out that there several different types of radon testing. That does seem like a good thing to be aware of when you need to look for a company to do this. After all, you will want to know what type of testing will match your needs best.

We Are Open!

First we would like to say our thoughts and prayers are with all of those affected by COVID-19. We would like to also express our sincere gratitude for all of the first responders and their hard work.

In light of recent news regarding COVID-19 in Michigan, The Department of Insurance and Financial Services, inspections are deemed an “Essential Service”, and our office has implemented policies in line with what the Center for Disease Control and Prevention and the Department of Health and Human Services are recommending. All of our inspectors have also taken and passed the International Association of Certified Home Inspectors (InterNACHI’s) class COVID-19 Safety Guidelines for Home Inspectors and gained Certification.

Keeping Everyone SAFE!

Typically, we encourage our client(s) to attend their home inspection however, the current COVID-19 guidelines dictate that we no longer are allowed to have our client(s) or their agents  attend the inspection. Our inspectors will call the client at the end of the inspection and once payment is received to briefly sum up our findings. In addition, we require that the sellers must also vacate their home during the inspection. In order to comply with CDC guidelines, if they do not have another residence they are welcome to stay in their vehicle, at the premises, during the inspection.

During inspections we will: 

  • Wash hands multiple times during every inspection, especially after touching things like faucets and door handles.
  • Bring hand towels or paper towels for drying our hands. 
  • If available, we’ll keep hand sanitizer nearby and use it when needed.
  • If available, use disinfectant wipes or the equivalent on faucets and door handles.
  • We will not shake hands or bump fists.
  • We will avoid touching our faces.
  • If requested by the seller, our inspector will wear a mask during the inspection.
  • If any of our inspectors have a fever or cough, we will not conduct the inspection.
  • If any of our inspectors have been exposed to COVID-19, we will not conduct the inspection.

Likewise, if anyone in your household has tested positive for COVID-19 in the past 21 days, have come in contact with someone who has, or if you are experiencing any of the following symptoms, we kindly ask that you reschedule to a later date:  

  • Fever
  • Coughing
  • Shortness of Breath

Thank you again for trusting Trademark Home Inspection, LLC with your inspection needs and please feel free to reach out if you have any questions or concerns.
