What Is Radon Gas?

Why Is Radon Gas Testing Necessary?
When you’re in the market to purchase a new home or if you’re just maintaining your current home or business, radon testing should be a high priority on your checklist. The negative health effects of living in a home – or working in a building – with high radon levels is the main reason you should have your home inspected. The fact that you can’t see, smell, or taste radon is another reason it’s so important to have a professional test the air. Your family’s life could be at stake, and having the peace of mind that your home or business doesn’t have high levels of radon is priceless.
How Radon Gas Enters Your Home
Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water. Air pressure inside your home is usually lower than the pressure in the soil around your home’s foundation. Because of this difference in pressure, your house acts like a vacuum, drawing radon in through foundation cracks and other openings. Your home then traps the radon inside, where it can build up. Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements.
Radon may also be present in well water and can be released into the air in your home when water is used for showering and other household uses. In most cases, radon entering the home through water is a small risk compared with radon entering your home from the soil. In a small number of homes, the building materials (e.g., granite and certain concrete products) can give off radon, although building materials rarely cause radon problems by themselves. In the United States, radon gas in soils is the principal source of elevated radon levels in homes.
Frequently Asked Radon Gas Testing Questions
We tend to book out between 5 and 10 days however we know time is a factor and the inspection needs to be done sooner than that. In those cases we do everything possible to fit your inspection in, as long as it doesn’t make it so the inspector will have to rush anyone’s inspection.
The test must be set up in the home for a minimum of 48hrs, and because we use continuous radon monitors we will know your results as soon as the test is completed.
Though our Technicians are certified to install radon gas mitigation systems, we do not offer this service as we feel it is a conflict of interest.

Paige CookNovi, MI 
Excellent service! Joe was Very friendly and respectful. He even showed up early and started before we arrived. He Went over results with us on the spot, was easy to talk to and very helpful. Being a first time home buyer, I am so happy I chose this inspection company. Highly recommend.
Casey MoranRiver Rouge Michigan 
Chris and Mitch were extremely helpful and professional. Chris explained the process very clearly and the results thoroughly. Recommend to any of my friends who are in the home buying process
Natalie WardSouthfield Michigan 
If you ask my ex wives, I'm very hard to please. I generally refuse to leave reviews unless I was very impressed or very disappointed; this is one of those times.
I priced multiple companies, and this one was on the higher cost side. However, this is one example of you get what you pay for.
Joe was my inspector. He was extremely detailed, listened to all of my concerns, gave honest solutions, and followed through with every question. I applaud his level of detail and professionalism. Excellent people skills with a lot of shareable knowledge. Working with him placed many of my concerns at ease when considering the purchase of a home.
QuinnEcorse Michigan 
Mitch did my inspection for a 2nd time in my process to find my first house and did a great job going the extra mile once again. Was able to walk me thru things and teach me some things and even giving possible rough estimates on costs.

Kayla BurtonClarkston MI 
Fantastic job! Easily the most thorough inspection I've ever seen. Mitch was the reason I wanted your company to do my inspection. He inspected the house I just sold. I will definately recommend your company to anyone I know needing an inspection. Thank you for a job well done
Brad DavidsonAugusta Township Michigan 
It was a miracle Joe was able to come out and do the inspection as quickly as he did (we booked 2 days before). He was very thorough and explained everything in words a first time homebuyer could understand, and managed to convince my Father that it was a good house with relatively minor issues (another miracle)!
