"I used Radon Abetment Services LLC to install a radon system in my basement. John and his team were excellent and I highly recommend them to anybody with this need. John was able via video over phone identify where the system should go. His team was extremely professional and courteous. The installation took a day and the improvement in radon levels was remarkable. We would absolutely use them again."

"Randall did a radon test which I needed for the sale of my home. He scheduled to install the unit the next day and showed up right on time. He explained everything about the process and left a printed reminder. Before leaving, he scheduled the day and time to pick up the tester - and again, he arrived right on time. He emailed the results to me within two hours of picking up the test unit. WOW! This is what I call excellent service! I highly recommend Schmid Home Inspections."

"During the initial contact, I was impressed with the explanation of the testing process provided by the individual who answered my call. I was equally impressed by Mr. Robinson's step-by-step explanation while he set up the equipment to perform the test. He explained his licensing and the accuracy of the test that he was conducting. He was professional, efficient and possesses a great deal of expertise in his chosen field. He informed me when to expect the results of the testing and followed up with a phone call explaining the report in minute detail. Looking forward to working with Mr. Robinson for the next step in this process. Thanks again. -- Roger K"

Radon Detection and Reduction questions, answered by experts

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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).

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

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