We are a family/friend owned business specializing in Radon testing and mitigation. Eric is a Veteran having served in the U.S. Navy and Blake is currently a Marysville fireman so we're not afraid to go the extra mile to make sure you're completely happy from start to finish. We are quick and precise and treat your home as if it were ours. You can expect professionalism and a lot of courtesy from start to finish. Let us help you with your Radon Gas issues!

"Eric contacted me shortly after searching Angie's List. I described what I needed, a radon mitigation system, and he provided a written estimate via email. Much lower than what I expected. Eric was able to come out in a few days and install the system. Installation time was about 3 hours. No additional charges. He returned to the house three days later to retrieve the radon monitor and showed me the current reading of 1.0 pC/l, well below the 11.0 pC/l from a prior test. A formal report was emailed the same day; the avg reading was 0.8 pC/l. I highly recommend hiring Radon Fix."

"Absolute WORST experience I’ve ever had with a company! They are extremely predatory and convinced my 63 year old mother that she had to sign the contract THAT DAY, and she didn’t even understand what she was signing! The first day they were scheduled to do the job, they showed up hours late, and said they “weren’t the right crew to do the job”. We then had to wait a couple weeks for a different crew to come, and when they came they said they weren’t the right crew to do the job either!! 2 weeks later, ANOTHER crew came and said THE SAME EXACT THING!!! So after 3 times of getting the runaround, I was completely FED UP with this horrible company and decided to cancel the contract. They FINALLY did let me cancel, but are demanding we still pay $600! After all they put us through over 3+ months, they had the nerve to charge us $600 for an outlet! PLEASE AVOID THEM AT ALL COSTS! All they care about is dollar signs, not about the QUALITY of their work or customer service."

Radon Detection and Reduction questions, answered by experts

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.
