"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

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.
