"Mark is very thorough and explains findings well. Took his time and when he picked up the radon tests a few days later, he took another look at the exterior as it was raining the day of the inspection. Great customer service."

"Biotek is the best, most compassionate company I've ever dealt with. All the employees were top professionals with a very kind heart & ever so helpful. They answered all my questions honestly & were concerned about my health. All were knowledgeable, well trained, courteous, & performed the testing & remediation efficiently. They blocked off the place where the mold was found & protected me from any mold spores or mycotoxins the the remediation could stir up. They brought huge air scrubbers to my house to suck up all bad stuff in the air & used a special vacuum cleaner to clean the carpets, as well as cleaning the furniture. They thoroughly took every precaution & measure to get rid of all toxins & poisons from the mold that have made me so sick. I am so grateful for Biotek & pray for all in the company everyday. May God bless them more than they could ever ask or think."

Radon Detection and Reduction questions, answered by experts

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

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.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.
