"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

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

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

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

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