"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."

"It went very well! Tim came to the apartment and looked at the issue. He told me that he will place the order for the new and more efficient unit than the old boiler and install asap. Tim's crew came the following Monday to demolish the old boiler and installed the new boiler on the same day. The new boiler was up and running on the same day. It was a smooth startup!"

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."

Radon Detection and Reduction questions, answered by experts

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

You should have a professional test for radon every two to five years. A good rule of thumb is to get testing done every five years if you’ve never had an issue before and every two years if you have. You may also want to schedule testing if you notice symptoms of radon exposure or if you do intermittent DIY radon testing and notice changes in your levels between tests. If you have an active radon monitor, you can schedule testing if you notice levels increasing over time.

It is worthwhile to get radon testing done, especially if you haven’t in the past and don’t have active radon monitoring set up in your home. According to the American Lung Association, radon is a potential issue in all states, and testing is the best way to determine if it’s a current problem in your home. Radon testing includes professional tests that determine ongoing radon levels in your property, and it usually includes a mitigation protocol to help you decide what measures to take to protect your home and household members.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness
