"TESTING FOR ASBESTOS I need to make sure people know about a man named Jeff Miller Owner of Scope Environmental. I wanted to have my basement checked for Asbestos. This man was absolutely the nicest person. Jeff is a professional, who explained things extremely well and in detail, offered positives suggestions, and extremely knowledgeable. Oh, and extremely honest and helpful. If you ever want to have your basement checked for Radon or Asbestos or Mold, please call this nice man who has a vast amount of experience and knowledge on these three issues. His phone number is 314-220-1810. His pricing is very reasonable and he is Certified in the State of Missouri which is a requirement by the State to do testing. He sure put my mind at peace."

"We were in the depths of nesting when we realized we were running out of time to paint the nursery before our first baby arrived. We live in an older house, so we were quite concerned about lead safety as well as minimizing paint fume exposure for my wife and newborn. We realized we needed to work with a professional who could take all of this into account and act quickly to make sure the room was ready in time. Kenneth was very accommodating to us. I'm confident we were challenging to work with given the circumstances, but he never made us feel that way. He took our concerns seriously and talked us through a variety of options to find something that worked for us. He was kind, responsive, and moved quickly to keep us on schedule. When we had notes or changes, he was quick to address them. There were a few aspects of the finish that weren't as polished as we hoped, but overall he was great to work with. The project was completed on time, and we were grateful to have his help during such a stressful moment."

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.

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

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

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.

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