What is Radon?

Radon is a colorless and odorless radioactive gas that can enter your home through cracks in the foundation. Radon poses health risks to those exposed to high levels of it over a long period of time, with lung cancer being the number-one risk. As such, many property owners skip an inspection for radon out of unawareness or fear. This is due to common myths surrounding the gas and its health effects.

Is There a Safe Level of Radon

The United States Environmental Protection Agency (USEPA) has determined that a measurement of less than 4 picocuries per liter of air is a safe level. Once the concentration of radon reaches 4.0 pCi/L or above, the USEPA recommends that property owners take action to reduce the amount of radon and protect their health.

When inhaled or absorbed in small quantities (less than 4.0 pCi/L), radon is not considered a health threat. If testing reveals levels above the norm, further analysis is necessary. Both odorless and colorless, it is impossible to detect without special equipment, and prolonged exposure can lead to lung cancer.

Where Does Radon Come From

Radon is a naturally occurring gas that occurs as part of the natural breakdown of uranium in the ground. This radiation is not always dangerous but can increase the risk of lung cancer, making it important to test your home for radon levels. Exposure to radon can be a health threat if you are exposed to elevated levels. This includes well water, lakes, rivers and soil found near your property. Testing your home for radon is essential because even low levels of radon exposure may impact your a person's health over time.  That's why every business needs to protect their employees with a commercial radon inspection in Ohio.

How Does Radon Enter My Home

Radon enters the home through cracks around the house and holes in the foundation. As uranium, which naturally occurs in the soil, decays, it turns into radium and gives off radon gas. This odorless and colorless gas can easily seep through tiny cracks.

In addition, decaying matter can also attach to building materials, which means that low levels may be detected in drywall, granite countertops, and other areas of the home. Getting your foundation and crawl spaces inspected is part of the prevention process, but the only way to ensure your home or business is safe is to have the property specifically tested for radon.

Radon Testing in Ohio

What goes into radon testing in Ohio?

How Do I Test for Radon?

While homeowners do have the option of purchasing DIY radon testing kits, the best option is to hire a highly trained and licensed expert to conduct the testing. A passive test kit might give you a general reading, but it is only a short-term solution. If high levels of radon are detected, you will have to invest in a professional inspection that will pinpoint the source of radon and make specific recommendations for reducing your exposure, ensuring radon gas remains at a safe level.

What Does a Radon Inspection Involve?

The good news is that conducting a professional radon inspection is relatively easy. A licensed inspector will use active devices that require power to function and continually monitor radon levels. These devices will be placed in the lowest level of the home that is used regularly. For the best results, the testing device should be set up in an open area. Placing it in a closet or other enclosed space may produce inaccurate results. Using active electronic devices will not only prevent but also detect test interference so inspectors can accurately read the results. Electronic testing devices are also useful because they will report any abnormalities or swings in radon levels, which can be caused by seasonal changes and other factors.

How Long Does a Radon Test Take?

At an absolute minimum, a radon-detecting device should be placed in the home for a full 48 hours. However, 90 days is still considered a short-term test. Often, a long-term test of over 90 days is used to confirm short-term test results and produce a report that includes seasonal variations. Property buyers may not have the luxury of waiting over 90 days for a radon test. In this case, any reading of 4 pCi/L or over should result in repairs being made to the home.

How Can I Lower Radon Levels in My Property?

The easiest way to lower radon levels is to seal any cracks and openings in the foundation. While this may prevent some radon gas from entering the home, the best way to significantly reduce levels and implement a long-term solution is to install what is known as a sub-slab depressurization system. These systems use a combination of vents and fans to direct radon gas away from the home. While the exact configuration of each system will vary according to the individual home and its specific challenges, you will never have to worry about making major changes or renovations to your home. Any system can be easily installed.

What Areas in Ohio Are Radon Levels the Highest?

The prevalence of high radon levels varies across the state of Ohio. As you can see from EPA Map of Radon Zones, much of the northern half of Ohio is labeled as Zone 2, which means that the EPA predicts indoor levels of radon gas to reach or exceed 4 pCi/L, which is the level they recommend taking action. Many of the southern counties and areas of the northwest are listed as Zone 3 areas, which have a low potential for radon gas.

Which Ohio Counties Have the Highest Concentration of Radon Gas?

As you can see from the map, many of Ohio’s centrally located counties are predicted to have the highest levels of radon gas concentration. This estimate is based on prior testing and environmental factors that produce radon. While the areas marked in orange and yellow will generally have lower levels of radon gas, residents and property owners in these areas should still have their residential and commercial buildings tested and demand an inspection before purchasing.

Why Is Ohio at a High Risk for Radon Gas?

The state of Ohio is home to two unique geological formations that make its residents at an especially high risk of exposure to radon gas. Much of the state is covered in a shale outcropping. This special type of sedimentary rock contains organic materials that naturally break down and produce radon. In addition, Ohio was formed by glaciers that deposited sediment that is also known to be high in radon. Combined, these two factors create a perfect storm for producing high levels of radon gas in Ohio homes and businesses.

Radon in Schools

Children are especially susceptible to radon poisoning. At 4 pCi/L, a student's radon exposure is the same as smoking half a pack of cigarettes each day. In a school year, students exposed to 4 pCi/L will absorb around ten times the amount of radiation allowed outside a nuclear power plant!

Nationally, nearly one in five schools has at least one classroom with short-term radon levels above 4 pCi/L. EPA estimates that more than 70,000 schoolrooms have high short-term radon levels. At this level, the EPA recommends you take immediate mitigation measures.

Because professional testing is the only way to know whether your school has high radon levels, Home & Commercial Inspections LLC will perform a thorough radon inspection throughout the premises, ensuring the safety and well-being of students and staff.

Even if your school fails the radon test, the problem can be remedied. There are procedures that have been shown to reduce radon levels and the risk of lung cancer caused by radon exposure.

Testing is straightforward and affordable. After all, radon is a health concern that no one should have to deal with, whether at home or at school.

Radon in Multifamily Housing

Many people in the US live in attached townhouses or low-, mid-, or high-rise apartments and condos. These buildings pose unique challenges because pollutants may move from unit to unit, and residents may be unable to structurally change their building.

Radon is the second-leading cause of lung cancer. Because safe radon levels are unknown, the EPA recommends property owners take action when indoor levels are between 2 pCi/L and 4 pCi/L. Our inspection is the first step to ensuring safe air quality for all occupants.

Large foundations and complex HVAC and ventilation systems are common in multifamily dwellings. As experienced, certified contractors for radon testing and mitigation services in Ohio, we provide the most thorough inspections to diagnose radon in your multifamily complex.

The U.S. Dept. of Housing & Urban Development (HUD) requires radon testing for mortgages for:

  • Multifamily Accelerated Processing (MAP)
  • Traditional Application Processing
  • New construction or substantial rehabilitation of multifamily housing
  • Purchase or refinance of existing multifamily rental housing
  • Building or renovations of rental housing for the elderly or disabled

Radon in Commercial Buildings

The potential for radon in commercial buildings should never be overlooked. Employees can spend eight hours or more a day at their place of work, and if radon levels are high, they are at risk of developing lung cancer.

Employers must make sure their workplace is safe and healthy; this includes testing for radon gas. There is no EPA-specified radon action level for commercial properties; however, we recommend applying the residential standard of 4 pCi/L.

Commercial buildings can have unique requirements and characteristics, which must be accounted for in an inspection, such as stronger indoor air flow and distinctive structural characteristics and radon entrance sites.

We were so impressed with James from our previous home inspection a few years ago that we requested him again for our new home. He was great back then and still is now. He’s very thorough and informative and has gone out of his way to our answer questions and provide us additional information. He’s very professional and has a great friendly personality. If we ever need another inspection we’d definitely be calling him again.

We requested to work with Greg based on the reviews that we saw and were so glad that we did! He was very responsive via text/phone - on our scheduled day, he showed up early and began inspection right away. His inspection was very thorough and professional. As we walked through the house, he also gave us (as first-time home owners) lots of valuable home maintenance tips. We are recommending Greg and the company to our neighbors and friends, and we will also work with him again for our 11-month warranty inspection!

James was timely, professional, responsive, and thorough. Making an appointment was easy and he was able to fit our tight timing needs for our home purchase. He found issues with our house that we would have never thought of. With all the stresses of buying a new home, it was a relief having James’ eyes and expertise on the job. He saved us hundreds of dollars in necessary repairs that we would have missed. When we buy our next house, James will be the first and only name on our list.

This is the best radon inspector service in Columbus, Ohio

From experience being a loan officer working in mortgages I can say one of the most important parts of the purchase is the inspection. I hired James based on the realtor's recommendation. Great with communication and a straight shooter when it comes to issues with the house. He's very knowledgeable in every aspect of the house and I can say he saved us a ton of money but getting the seller to fix issues that we didn't even notice.

I received a home inspection from James and really had such a great experience and was happy to write a review about it.

1. Prior to the inspection he took the time to explain to me his credentials and experience in the field of home inspection-this allowed me to get to know him and feel comfortable about his knowledge of the field. This really meant a lot to me and really was one of the reasons I chose him to do my inspection because he just made me feel so comfortable and confident in my upcoming inspection. Before the inspection he also sent me a sample report as well as shared with me his company website which included helpful customer testimonials. Also he was very easy to get a hold of and at last minute was able to reschedule my inspection.

2. The day of the inspection he was on time professional and very approachable. He did a very detailed inspection and explained to me everything he was doing and all of his findings-which I really appreciated as a first time home buyer and single woman who does not know much about home repairs. He came very equipped with appropriate tools. James was also very conscious of my time and left no stone unturned during the inspection. He picked on things that were certainly important that I would have never even thought of.

3. After the inspection James wrote up the report very quickly and I received it the same day the inspection was completed. The report was very easy to read, follow and understand with all of his recommendations rated by level of importance.

Overall a great experience and service that I would recommend to any home buyer in need of inspection.

Excellent and professional service! Top notch quality before and after services were complete. James even recommended qualified contractors to help with improvements after his home inspection. Never had a better inspection on a home. Not only pointed out issues, but was knowledgeable on how to fix them. 10/10 would recommend.
