Radon Testing

Why Radon Testing Matters

Because radon is tasteless, odorless, and invisible, this radioactive gas is a hidden threat in homes and businesses throughout the United States. There is no geographical area in the U.S. that is exempt from radon exposure, so the only way to know if your home or business has dangerous levels of radon is to test for it.

Radon testing is so critical because of the significant health risks radon exposure presents. According to the EPA, radon is the second leading cause of lung cancer among the general public and the first leading cause among nonsmokers.  Learn more about radon from the EPA.

Green Earth Remediation can help you gain peace of mind or understand the next steps necessary for radon mitigation with reliable radon testing services for residential and commercial clients.

How Often Should You Test for Radon?

Radon levels fluctuate through time, so testing just once is not sufficient for assessing your risk of exposure. Homes and businesses should be tested once every 5 years.

When to Test for Radon

Additionally, you should test for radon under the following circumstances:

  • When new occupants are moving into the space.
  • After significant alterations during a remodel or building addition.
  • When the ventilation, insulation, or HVAC system is installed, altered, or repaired.
  • When the structure is being weatherized.


The Importance of Regular Testing

Regular testing for radon is essential for maintaining safe radon levels in your home. Periodic testing ensures that any changes in radon levels are detected early, allowing for timely intervention and safety measures.

Why Radon Levels Might Change Even with a Mitigation System

While radon mitigation systems are highly effective, several factors can cause changes in radon levels over time:

Structural Changes

  • Building Settling: Over time, buildings naturally settle, which can create new cracks or openings in the foundation, allowing more radon to enter.
  • Renovations: Remodeling projects, such as adding new rooms, changing HVAC systems, or altering the building’s structure, can affect radon levels.

 

Environmental Factors

  • Weather Conditions: Heavy rains, snow, and other weather conditions can influence soil moisture and radon levels. For instance, saturated soil can increase radon concentration in the ground air.
  • Seasonal Variations: Radon levels can fluctuate with the seasons, often higher in the winter when homes are sealed tight against the cold, trapping radon indoors.

 

System Wear and Tear

  • System Maintenance: Like any mechanical system, radon mitigation systems require regular maintenance to function optimally. Components like fans can wear out over time and may need replacement.
  • Blockages: The vent pipes used in mitigation systems can sometimes become blocked or damaged, reducing their effectiveness.

 

Ground Shifts

  • Natural Changes: Earthquakes, mining activities, and other geological events can shift the ground, altering the pathways through which radon travels.

 

Ensuring Continued Safety

To ensure that your mitigation system continues to protect you from radon, it’s important to:

  • Schedule regular inspections and maintenance of the mitigation system.
  • Retest radon levels periodically, even after a system is installed, to confirm its ongoing effectiveness.
  • Be vigilant about structural changes and repair any new cracks or openings in the foundation promptly.

 

Ongoing Protection

Regular radon testing is crucial for the safety and well-being of your household or business. By staying vigilant about testing and maintenance, you can protect your property from the dangers of radon exposure. Reach out to Green Earth Remediation for professional radon testing and mitigation services to keep your environment safe and secure.

Types of Radon Testing

There are various types of radon testing, including short and long-term tests. Short-term tests measure radon over a brief period, as little as 48 hours. These tests may be performed with passive testing kits purchased at hardware stores, online, or provided for free in certain states. These kits provide instructions for use and are sent to labs for testing. 

Alternatively, active testing with continuous radon monitors may be performed by professionals like the technicians at Green Earth Remediation. This will be the fastest and most accurate form of testing available.

Long-term testing may be recommended if short-term passive tests indicate higher levels of radon or if you want to assess your home or business’s risk over an extended period. Radon levels tend to be highest during the winter due to the thermal stack effect—cold temperatures increase pressure within the home, drawing more air from the soil and causing higher levels of radon accumulation.

We recently had a radon mitigation system installed in our home and I highly recommend Green Earth. The entire process was so quick and easy. The install team of Joe and Derek were so friendly and clean. The process and equipment was non-intrusive and they took the time to explain everything as they went. We especially appreciated the follow up test and guarantee that radon levels will be at 2.0 or lower. Help keep yourself and your family safe and book with Green Earth for an excellent experience!

This company overall was an excellent experience to deal with. Joe (and his partner I can't remember his name) were fast and very professional with the install. You could tell Greg was also very invested in the company to ensure a quality service is provided.

Green Earth Remediation did a great job helping us lower our house radon levels. They were very responsive and came out within a day or two. They installed a fan to our passive system and returned a few days later to read the report and assure us that our home was now safe from radon. Excellent service at a very reasonable price. We highly recommend Green Earth Remediation.

Huge shoutout to William for the radon mitigation work at our home. He made the whole process easy, explained everything in plain English, and the system looks great. You can tell he actually cares about doing the job right. Also, I’ve got to say — the man rocks a seriously awesome hat. Five stars all around.

I had a great experience with Green Earth Remediation. Initially, I called to ask questions about my home digital radon tester placement. And that led me to realize my storage room with my sub pump was over 6. I appreciate the willingness to educate about radon, everyone I interacted with was happy to answer my questions. William did the mitigation system installation, sealed our sub pump basin, and left a professional grade radon tester (free of charge) to monitor the effectiveness of the system. He was very helpful and efficient, and also was wonderful at answering my questions. Greg came to collect the system and went over the results with me, which was a big improvement (.3)! We have a bedroom in our basement, so this was a huge relief. Our personal detector also reflects this improvement. Thank you Green Earth Remediation!

There's really no other radon remediation team that will care about your home and family more than Green Earth. From the initial visit for the estimate to the final re-test after the system was installed, we were treated with respect and genuine care. When the first radon test came back high, it was pretty concerning. Greg and his team made sure we were comfortable with the plan and location for the system, as we have a new build, and the system was installed and up and running in no time. We definitely sleep easier knowing radon is no longer poisoning our family. Green Earth can not be beat!

Matt and his team were outstanding. We had a problem with the location the radon system was installed (the problem was rainwater water under the foundation) not Green Earths problem. They installed most of the system and we waited until the water went away. Never were they pushy to finish the job. They wanted it done right and so did we. Outstanding team and company to work with. Will be highly recommended by me to anyone who asks. Before remediation 5.8 pCi/L, after remediation 0.8 pCi/L. I know each house is different, but amazing results.

Joe came out to install my radon mitigation system and I have no complaints. During the install a storm came through and took out the power lines so Joe was stuck for a while at my house. Even after the power went out Joe finished up the job. After he sat with my dad and myself for probably five hours due to the down lines and talked with us, played us his harmonica, and ate dinner in the driveway with us. He was a great guy and would highly recommend Green Earth, specifically Joe to anyone needing a radon mitigation system. I would also recommend Green Earth because they actually can out to my house (quick response) to talk through where to route the pipe and answered all my questions. While they were slightly more expensive than the other company that quoted me, I felt a lot safer going with Green Earth because they saw my house prior to installation day and guarantee levels below 2.

The Green Earth team was fantastic. We were frightened to find out we had high radon in our home and their team installed our mitigation system quickly and efficiently. Their staff was very informative and advised us on the best ways we could have the mitigation system installed based in our home and its layout. Thanks to the Green Earth mitigation system, our homes radon levels dropped from 8 pCi/L to a .7 pCi/L.

If you are looking for a professional and reliable team for radon mitigation, I highly recommend **Green Earth**. I contacted three different companies for estimates, and Green Earth was the only one that actually came out to my home to assess the space and explain the entire process in person. Their transparency from the start made a huge difference in my decision. The level of service and confidence they provide is unmatched. While other companies would only guarantee radon levels below 4.0, Green Earth guarantees levels under 2.0. They didn't just install the system and leave, either—they monitored the levels closely after the job was finished to ensure everything was functioning exactly as it should. Every employee I interacted with was knowledgeable, professional, and pleasant to work with. It is rare to find a company that combines technical expertise with such high standards for customer care. If you want the job done right, go with Green Earth!

Friends recently had a system installed and were very pleased. We saw Green Earth's booth at the Grand Rapids Home & Garden show back in February and signed up for a Radon test. The Monday after the show they called and we scheduled a test for later that week. One of their staff came out and set everything up. Test takes a couple of days. When it was done he came back and showed us the "not good" results. It was 3 times the passable level. With that information we went ahead and scheduled the installation of a Radon remediation system at what I thought was a very fair price. Their installer showed up on the scheduled day and within a few hours we had the new system up and running. Very professional install. A short time later they brought the test equipment out and after the prescribed time came back and showed us the "new" test results which were well below the minimum acceptable levels. Very pleased. No high pressure sales. Staff were polite and easy to work with. Answered all our questions. I give them a five-star rating and would at minimum recommend you have them come and test your home for Radon.

Radon Testing FAQs 

Radon testing should be performed in homes and businesses every two years. If results are below 4 pCi/L, retesting may occur every 5 years.
It’s a common misconception that radon is only a problem in older homes and buildings. However, radon levels can build up in any indoor space, even if the building is newly constructed or renovated. Before moving in, schedule radon testing to ensure your safety by reducing the risk of radon exposure.
Radon is an invisible, odorless, radioactive gas. The only way to know that indoor radon levels are high in any given space is to perform radon testing. Radon is so dangerous because it is the second most common cause of lung cancer, behind cigarette smoking.
It is possible to test for radon using a DIY radon testing kit purchased online or at a hardware store. These kits are mailed to labs for testing after they have been placed in a home or business for a designated period of time. However, if you need radon testing with rapid results or you want to confirm the results of a self-test kit, calling a professional is recommended.
Short-term radon tests measure radon levels over a period of 2-90 days, while long-term test kits measure radon levels for 90 days or longer. Radon levels fluctuate through time, so the results of a short-term test may not accurately reflect average annual levels of radon in a home or business.
Radon is everywhere, indoors and outdoors. However, indoor spaces can trap radon inside as it breaks down and seeps into homes and buildings via the cracks and holes in the foundation. Any home or building, regardless of its age, location, or size, may have a radon problem. The only way to know for sure is to perform routine radon testing.
Radon levels are not static. They fluctuate due to a variety of environmental conditions, so routine radon testing is necessary to continually manage the risk of radon exposure.
There have been numerous studies both in the U.S. and internationally that have linked radon exposure to an elevated risk of lung cancer. There is no truly safe level of radon, but routine testing and effective mitigation systems can reduce the risk as much as possible.
