"Best description? Superior work. Thoughtful interaction and patience with the many questions. This was my first experience with work of this nature. Bo, the manager, could not have been more helpful. Alex and Ford worked endlessly to mitigate the mold and at the same time were informative and attentive to my questions. Excellence is the word that describes both their effort and the manner in which they took time to educate me on the remediation. Bo went out of his way to respond to both issues and questions."

Radon Detection and Reduction questions, answered by experts

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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. 

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.
