"It went great. I highly recommend them. They were a pleasure to deal with. The person that came out for the estimate answered all of my questions. The estimate was fair. The work was done on schedule and with no problem. At completion, everything was explained to me. I used their electrician which worked out fine. After completion the radon test showed that my level was now undetectable."

"This is a high quality mold/fungi/fungus testing company, with excellent customer service and follow-up. The phones were picked up on the first call each time, and arranging for an appointment was very easy. They arrived on time, were efficient, informing, and friendly in their work, and brought commercial equipment to perform the test samples. The follow up phone call and email on the test results was good, and they provided a potential remediation plan for us to follow on the test results. The third party lab utilized by them had easy to understand numbers, graphs, and descriptions of what was tested. We will do business with Gardner Services again in the near future, and will recommend them to others."

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.

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

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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