Radon is a tasteless, odorless, invisible, radioactive gas that occurs naturally in our environment. It can cause damaging health effects, including lung cancer, when it is inhaled for prolonged periods of time.

It is the heaviest gas to have been discovered so far and it continuously emanates from the ground into the air all around us.

What is Radon and How it Enters the Home


Radon is an indirect decay product of Uranium, which is present in natural gas, water, rock, and soils.

Radon generates within the soil and travels into a home through its foundation. Pressure variations between a building’s foundation and the soil result in a vacuum-like condition that pulls Radon gas into the home through cracks and small openings in the foundation. 

When Radon gas seeps into poorly ventilated buildings, it cannot be diluted. This may result in significant levels of accumulation, presenting potential serious health risks to you and your family.


Outside in the open, Radon byproducts quickly disperse. inside, it’s often a different story. Outdoor concentrations of Radon are typically safe and measure at about 0.4 picoCuries per Liter of air (pCi/L). However, when the Radon enters your house through the basement floor, crawl space, or slab flooring, it can build up inside your home to levels far in excess of that found outdoors.

 Without the benefit of wide-open spaces, this gas and the particles that cling to it tend to build up and become more concentrated. Since it’s heavier than the harmless gases in our atmosphere, it sinks to the lowest possible levels of homes and other structures.

In spite of being heavier, it also happens to be smaller than oxygen, hydrogen, helium, and other gases; allowing it to pass through virtually all construction materials. It gets into your home, and eventually into your lungs.


Radon is found everywhere in the environment, is present in all 50 U.S. states, and is a fairly common problem for Missouri. In fact, Radon is common enough to be known as the second leading cause of lung cancer in the United States, and according to the EPA, nearly 1 in 15 homes have elevated dangerous levels of Radon. In Missouri, those numbers are estimated to be 1 in 5.



According to the EPA, Radon is the second leading cause of lung cancer after cigarette smoking. An estimated 21,000 people in the United States die from Radon-related lung cancer each year. About 2,900 of these deaths occur among people who have never even smoked. While Radon is the second leading cause of lung cancer, it is the number one cause among non-smokers.



A simple test will precisely measure your home’s Radon level, determining any potential risks. If further action is warranted, EnviroTech Radon Solutions can safely and efficiently remove the Radon gas from your home.



Although no Radon level is considered safe, The Environment Protection Agency suggests taking corrective action with a home Radon test reading of 4.0 pCi/L or more.

EnviroTech did a great job. Decreased our radon level from 15.9 to 0.3. Didn't cost too much, and got the job done cleanly in a few hours.

Sherry Ruyle March 2022

Scott does amazing work, he is very well educated and is quick to respond. He has personally done work for me and I have referred him to others as well.

R N-StL January 2022

First step in improving future health risk for us and our families. Scott was helpful and answered all questions we had about testing to validate an initial charcoal canister test. Our next steps will be mitigation likely thru EnviroTech Radon.

BandL Orf February 2022

Scott was great and made everything really simple from start to finish. He was clear about options, pricing, etc. and did a great job. Highly recommend!

Ashley Cartlidge January 2022

Scott was incredible to work with. He provided a detailed quote before install, which was significantly less expensive than competitors. He was also able to hide the radon system in our garage and out our roof, so it is unnoticeable from the street. Our levels before install was 6, which now after install is under 1. He was extremely professional, courteous and we would absolutely recommend EnviroTech to anyone needing a radon system.

Jessica Purdy December 2021

Scott installed a radon mitigation system in my home recently. It was a great experience! He was quick, professional and did excellent work at a great price. We are so happy to have our radon problem solved. Highly recommend.

Katie Gilmore January 2022

Scott installed our pipe to mitigate the radon in our basement, and we are quite pleased with the service we received! It was done in a timely manner, was within our budget, and he was very kind and courteous.

James Sandfort January 2022

Scott was on time and did professional work. He answered all of my questions (and I had many). He was responsive to emails. The system was installed without any complications and the cleanup was great. Best of all the system has been working with radon levels below the level for concern. Highly recommend

L Ck March 2022

Excellent responsiveness, clean and quality work. Highly recommend for home sellers. Environtech exceeded my expectations with professionalism installing a proven system with warranty that exceeds other firms. Was impressed with how they used drop cloths to keep workspace clean and cleaned up after their job.
My thanks to Scott, Ben and crew for their capability to install and successfully test the system well before my closing date, at short notice and with no surprises on the reasonable price estimate!

Kim Blackmore February 2022

Scott @ Envirotech installed a radon mitigation system in the house I was selling in December of 2021.

His competitors should watch out because Scott is a triple threat:
*Flexible. This was an unforeseen need and Scott went out of his way to get it installed prior to our existing closing date, something no one else I contacted was able or willing to do.
*Affordable. While timing was more important than cost, Scott still came in below everyone else. Huge bonus!
*Reliable. His work seemed exemplary and was done on time. He also followed up to ensure the system was working properly.

Both myself and the home buyers were very pleased with the entire process. I would recommend Envirotech to anyone needing a radon expert!
