"Words cannot fully express how grateful I am to have found Biotek Environmental! Ted took a lot of time compassionately listening to my concerns and explaining the initial process over the phone. Tyler patiently shared his extensive knowledge on how mold develops along with natural ways to clean clothes and surfaces. He also explained the meter reads of mold counts and humidity levels as I tagged along from room to room during the home inspection. Every step of the process was clearly explained creating a great sense of confidence in me and Dad. Crew members Jermaine, Ray, and Matt were friendly, considerate, and diligent in their hardworking task of removing the mold source. Donna was very professional and prompt to respond to any questions by email. I could go on and on with how pleased and relieved I am to have found Tyler and company but I will just close by stating the obvious: health is vital. My elderly father's health and general quality of life have improved substantially since we hired Biotek Environmental. They are also a clean company with a generous warranty. I highly recommend them to anyone in need of a healthier home."

"Tim did a great job. He came out and assessed the job. This was a real estate transaction, so he made the timeline work for us. He even completed a few of the other items on our punch list. We got the reduced reading as we needed. Tim is willing to support the new owners questions as well. Great job Tim."

Radon Detection and Reduction questions, answered by experts

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

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.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

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.

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.
