Radon Mitigation Effectiveness in Wisconsin for more than 30 Years
We've Been Reducing Radon Gas in Wisconsin for more than 30 Years
Experience makes the Difference
Hello, I'm Gregg Zetzman. For more than 30 years, I have answered the call to reduce radon in homes and businesses. In fact, I have reduced deadly gases for more than 6000 clients, designing every system myself!
I have been invited many times to speak about radon as a guest speaker at business gatherings, radio programming as well as print news. Nothing beats experience, escpecially when dealing with difficult radon gas!
Certified by National Radon Safety Board (NRSB)
The listed goal of the NRSB is as follows:
The primary objective of the Board shall be the development of standards and procedures for certification of radon testers and mitigators, the development and administration of examinations leading to certification, the awarding of certificates, the issuance of written proof of certification to individuals who satisfy requirements for certification, and the revocation of certification. The Board shall also develop standards and procedures to establish that certified radon testers and mitigators are knowledgeable of new developments in the profession through continuing education and have remained active in providing radon services.
State of Wisconsin recognizes and lists NRSB CERTIFIED Radon Professionals

PLEASE NOTE THESE INCORRECTLY INSTALLED RADON MITIGATION SYSTEMS

One example of many incorrect and improper systems installed by certified contractors or Radon Mitigation DIY- installed NOT TO EPA protocol.
- The fan is in the living space
- The pipe is blowing at ground level.
- No sump pump cover-meaning no air tight cover on it.
If the fan housing or piping above the fan (joints and pipe fittings) would leak, they would leak into the home. If the fan is in the floor next to the crock, then the fan is losing pull.
Obviously an unsuspecting consumer or buyer would think they have and paid for a properly designed system consistent with EPA NRSB NRPP AARST protocols. This system will very likely be flagged when inspected next time by a knowledgeable home inspector and could be dangerous

Using Quality Materials, Technique & Technology
Whether we are providing reducing radon services in homes, condominiums, institutions, schools or commercial, we take pride in the materials we use. Only quality materials and technology will go into our radon reducing systems. Many techniques and materials used by unlicensed and unfortunately even some certified mitigation contractors fall short. In fact, some materials and techniques can cause other toxic issues
This video gives a glimpse at what radon looks like. Now imagine yourself living in a home with high radon levels and breathing radon into your lungs and into your body every day.
Sub-slab method removes radon before it enters the home.
Specializing in Sub-Slab Radon Mitigation
GET THE RADON OUT BEFORE IT ENTERS THE HOME!!!
Every Radon Mitigation System is Designed by Me: Gregg Zetzman
My company keeps it local and personal! Each and every radon system installed, is designed by me. Many larger radon mitigation companies will just send a crew out to a home and let their crew deal with wherever is the easiest. These crews often cut corners or do not utilize all remediation methods to ensure a successful radon system and radon mitigation cost estimates.
I give my 20 years experience input before the job, designing the system, throughout the installation, and always approve the final completion of that job.
Active Sub-slab Radon Mitigation (SSD - Our preferred method)
The most common approach used is known as "Active Sub-Slab Depressurization" or (ASSD). This method involves drawing the radon gas (and other pollutants) from soils that are directly adjacent to the structure. In order for this method to be effective, a sealed barrier between the home and the soil must be available to divert the radon gas away from the home.
NOTE: Fresh Air Systems DO NOT REMOVE RADON, they only dilute the radon.
Some Homes can be more difficult to reduce radon
Many homes built after the 1940's have drain tiles. We can utilize these drain tiles in assisting the removal of radon. However, even homes with drain tiles can be difficult to reduce for an average mitigator with less experience.
Older homes without drain tiles can be reduced, but sometimes can require more mitigation work to reduce. However I am experienced with drain tile-less installs and will often get the call to reduce radon in homes other mitigators cannot. We are proud as a company to succeed 100% in any installation method.
Sale of a homes can be jeopardized if a radon contractor fails to reduce radon to under EPA levels?
Over the years, I have worked with many realtors, sellers and buyers. I have often heard nightmarish stories about how contractors promised to reduce radon and failed. Homebuyers can often walk away from a deal, leaving the seller with a lost sale and a radon system investment that is not reducing dangerous levels.
Heat Recovery Ventilation Radon Mitigation Method (HRV)
In a home with an inaccessible crawl space, limited slab accessibility, apartments, condominiums and other scenarios where active soil depressurization (sub-slab) isn't practical, a "Heat Recovery Ventilation" (HRV) can be used to treat radon problems.
Heat Recovery Ventilation (HRV) reduces radon levels by adding fresh air and creating positive air pressure. Negative air pressure in lower levels of the home creates a force that pulls soil gases, including radon, inside. By reducing the negative air pressure, Energy Recovery Ventilation can reduce radon levels while delivering fresh air into the home.
These two features make the ERV system a great solution for reducing radon and other contaminants in the home's air.
Repair and Replacement of inproper or non-working systems
Wisconsin does not license radon testing nor radon mitigation providers. However they do certify individuals who have taken training and register information with the state.
Unfortunately, many times these individuals miss the necessary reduction steps on systems or do not have the knowledge, experience, or expertise to be able to bring down difficult radon levels.
What determines where a radon system is placed?
Another specialty of mine is determining how well I can conceal my systems. When designing a system I will always study pictures, plans and consult with those who know the property. My goal is to always determine the best location for concealment. The homeowner and buyer input is always valued and encouraged.
Single, Multi-family, Institutional & Commercial Method
Our radon mitigation services include all buildings throughout Wisconsin. We are uniquely trained, certified and tested by AARST to perform many jobs in non-family buildings that some competitors aren't trained or certified to do.
We use both Active Sub-slab Radon Mitigation Method and Heat Recovery Ventilation Method for these types of buildings. We are AARST Certified in multi-family measurement and mitigation and can provide these services on HUD, FHA and all state and federal testing and mitigation requirements.
Beware of contractors claiming they are Wisconsin "licensed"
Our radon mitigation services include all buildings throughout Wisconsin. The state of Wisconsin does NOT license EPA trained radon measurement or mitigation individuals or companies. If any proclaims they are "licensed", the statement would be inaccurate. The state of Wisconsin does keep a list of Nationally certified individuals and companies. These companies, NRSB and NRPP qualify properly trained radon measurement and radon mitigation individuals.
