"I had an urgent situation on my hand and contacted 5 Microns because I saw the company had quite a few 5 star ratings. Pascal came out 2 1/2 hours after I spoke with him. He performed air quality testing and took samples of materials for asbestos testing. He took the time to explain the process and provided me with a good understanding of the testing process. He delivered the samples to the lab the same day and I received the results less than 24 hours later. Going forward, 5 Microns will be my first line of defense against a home remodel gone awry."

"My good friend recommended me Palm Construction on my roof replacement. I also contacted some other recommended roofing contractors and offer from Palm Construction was very acceptable. Lee and his crew started roof replacement soon after we signed a contract. Lee was very professional, honest and helpful. His crew kept working area clean as possible and they finished my roof quick and on time. The roof passed inspection and it looks great. I would highly recommend Palm Construction!"

Radon Detection and Reduction questions, answered by experts

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

Yes, many systems include warranties for performance. Confirm terms with your installer.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

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

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.
