"TESTING FOR ASBESTOS I need to make sure people know about a man named Jeff Miller Owner of Scope Environmental. I wanted to have my basement checked for Asbestos. This man was absolutely the nicest person. Jeff is a professional, who explained things extremely well and in detail, offered positives suggestions, and extremely knowledgeable. Oh, and extremely honest and helpful. If you ever want to have your basement checked for Radon or Asbestos or Mold, please call this nice man who has a vast amount of experience and knowledge on these three issues. His phone number is 314-220-1810. His pricing is very reasonable and he is Certified in the State of Missouri which is a requirement by the State to do testing. He sure put my mind at peace."

"K&E was very responsive to my request through Angi and came the same day (a Saturday) to review the work. He gave a reasonable estimate and completed the work the following Monday. I really appreciated the quick turnaround. However, he did not provide the contractcertifications and company info prior to coming to do the work as he said. He was not responsive to my emails and text messages about the contract and work start due to bad weather. Clean up was pretty good, but I did find chipped paint debris when I expected to all of that vacuumed away. That's why I gave a 4 point rating rather than a 5. I will not need to hire again because the lead and asbestos have been abated and there is no need for further work."

Radon Detection and Reduction questions, answered by experts

Mitigation reduces radon levels, protecting your health and complying with safety standards.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.
