"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

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.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.
