"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."

Radon Detection and Reduction questions, answered by experts

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

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

Installation typically takes 1-2 days, depending on the system and property layout.

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.

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.
