"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

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

DIY radon detection is possible using over-the-counter test kits, but professional testing can provide more accurate assessments, especially in cases of high initial readings.

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.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.
