"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.

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

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

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.
