"A small testing device was set up in our basement and was left in place three days. The device was then picked up and we received a phone call a day later informing us of the radon level detected. This was followed up by a professionally prepared report mailed to us detailing the results and how to interpret them."

"Radon Tec worked with me on a reinspection after mitigation. They understood my time demands and that I was living out of state. They completed task on time and on estimate price. Tech even forwarded invoice/results to the closing to give everyone a chance to review documents before closing. I would give a higher rating if I could."

"They contacted us immediately and were here the next day to test our home for radon. They were very thorough and inspired confidence. They also gave us a report of what they found. Also resonable prices!"

"I highly recommend Midwest Radon Services and I am relieved that the system installed was effective. Price was fair and competitive; all work was thoroughly and patiently explained with no pressure. Work was neatly and expertly finished. Suction under the basement slab was tested by measuring into a hole drilled then patched at the other side of the basement and turned out to be extremely good. The system continues to work extremely well with a sight verifiable U-tube monometer on the exhaust system continually monitoring. In addition, over 18 days since installation, the long term Radon readings, on two different digital testers purchased from Amazon, went way down from a maximum of 4.5, to a range of 0.83 - 0.6 during the time when the furnace was being used which is also a time that Radon readings tend to peak."

"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."

"Barry Schilling came out and quickly assessed the leak we had during the rain storm on 4/18/13.  He listened to the observations and conclusions of other contractors and tested their accuracy against his initial conclusion to let us come to our own conclusion.  He was patient and thoroughly answered every question we had, no matter how minor or significant.  He was at our property twice before we decided to choose U.S. Waterproofing.  The job was scheduled and the team of two men arrived on time.  Barry was there to walk them through the job first thing in the morning.  Except for the custom window well coverings, the job was completed on the same day and they were careful to clean up after themselves.  They had a lot of digging to do, and the fact that the temperature was in the 90's did not seem to slow the process.  The covers were done separately and were installed by the end of the week.  Shortly after the job was completed, we had another strong rain and saw water in the basement in a different place.  Barry came out and helped us to identify the nature of the leak which was completely unrelated to the leak that they fixed and had to do with some poorly designed enhancement to the foundation done by the previous owner of the home.
Barry was extremely knowledgeable, patient, and willing to make suggestions about how to address a variety of problems we had identified with our home.  He let us know exactly what to expect all along the way.  He was very pleasant and professional throughout the progress.  I would not hesitate to work with him and the company again and would to recommend them to anyone who had basement leakage.

Radon Detection and Reduction FAQs, answered by experts

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

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

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

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.
