Welcome! 
I'm The Radon Guy!

Let's Get Started

Radon Mitigation

We've perfected the process of diagnosing, mitigating and testing your home or business. We ensure a streamlined, stress-free experience. With more thousands of homes and businesses mitigated, our radon reduction systems have been fine-tuned to ensure a quick, smooth and effective installation.

Radon Testing

The Radon Guy uses state of the art radon measurement devices to test your home or business. With a low profile and silent operation, this device is the best option for people in the process of selling their homes. For homeowners, see our recommended devices for do-it-yourself testing and long-term monitoring.

Crawl Space Encapsulation

Transform your musty crawl space into clean, usable storage! Installing a sealed vapor barrier not only keeps your crawl space bright and dry, but helps with radon levels and adds value to your home. Next time you need to check something under the house, you'll be happy you have it.

Dehumidifier Installation

High humidity can cause many problems ranging from fungal growth to pest issues and cupping/crowing floorboards to rotted floor joists. A dehumidifier is an essential component to keeping your encapsulated crawl space or basement dry and preventing costly moisture-related issues in your home.

Custom Quality Work

Builders, realtors, and home owners can expect to get personal service from The Radon Guy. Give us a call and we can discuss your needs. We look forward to working with you!

A Variety of Installments

You name it, we've done it. I have personally installed mitigation systems in thousands of homes and businesses. I am confident I can solve your radon problems efficiently and honestly.

Get Started
People always ask me “Is radon all you do?”

… and the answer is always yes. In fact, it’s all I’ve done since 2008. I feel that it’s important to specialize in your business and not be a “jack of all trades”, because the other half of that saying is “master of none“. You wouldn’t want your plumber rewiring your home and you wouldn’t want your handyman installing something as sensitive as a radon mitigation system. I feel confident that I can make you feel good about your radon woes. Every home can be “fixed”... it’s just a matter of how to go about it. There’s nothing I haven’t seen and not a single home that I haven’t been able to mitigate. I am your radon guy!

The Radon Guy

Hi, I'm John Ottwein, also known as The Radon Guy. Since 2008, I have worked exclusively in radon. I initially became interested in Radon while working as a realtor in the family real estate business. Prior to working in real estate, I worked in construction. While I loved working with people, I missed working with my hands. As a former realtor, I know how important it is to get work done in a timely fashion to meet closing deadlines. I offer state of the art radon testing and customized radon reduction systems and will work with you to find the best option for your home or business.
