"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."

"RADMAN did an outstanding job installing a radon mitigation system in my home. His crew knows what they are doing and the results speak for themselves. Within hours after starting up the system my Radon level went from 20 to less than 1 Picocuurie per liter."

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.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

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