"Patrick was pivotal in credibly identifying safety, code, workmanship, quality, and structural issues on our home addition and garage project done by a Mason, Michigan builder who, despite being verified as licensed and insured with a 5 star review rating, proved to be a failure on all levels of home building. Until the inspection with Patrick of The Buyer’s Inspector, we had no idea how grossly misplaced our trust was in this builder. When COVID-19 shutdown our project we began noticing quality problems. This led us to hire Patrick from The Buyer’s Inspector. He was thorough, detailed, and spot on for the major problems as well as minor issues he identified during his inspection, including the multiple structural deficiencies. He recommended we hire a structural engineer to investigate these deficiencies in detail and the engineer verified all of Patrick's findings. It has been a very trying time legally fighting for our project to be done right but we thank Patrick for identifying all the problems using his extensive knowledge, experience, and understanding of Michigan's Building Construction Codes and industry standard building practices. Without his help we would have likely been stuck with this horrible build project that is riddled with safety, structural, workmanship, quality, and code issues. We highly recommend Patrick to anyone needing a thorough and detailed home inspection."

Radon Detection and Reduction FAQs, 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.

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.

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.

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.
