"We had the pleasure of working with Michael Gennett from MJG Home Inspections, and I can’t recommend him highly enough. Michael is incredibly thorough—there wasn’t a single question he didn’t have a clear, informed answer to. He encouraged us to ask as many questions as we wanted during the inspection and made sure we fully understood what we were seeing, which gave us a ton of confidence going into the purchase. He’s clearly an expert in older Chicago homes, which often come with their own unique quirks and issues. Michael spotted things we never would have noticed and gave thoughtful, practical advice on each item. Even after the inspection, he remained responsive and available for follow-up questions—something we really appreciated. His inspection report was fantastic: incredibly detailed, well-organized, and easy to follow. We shared it with several contractors for estimates, and every single one commented on how thorough and professional it was. If you're looking for a reliable, meticulous inspector—especially for older homes in the Chicago area—look no further than MJG Home Inspections. Michael is truly top-tier."

Radon is a naturally occurring radioactive gas found in the soil in Northern Illinois. It enters homes wherever the home is in contact with the ground. As we have improved insulation and worked to reduce energy costs in homes over the past 40 years, we have created an environment where radon concentrations have gone up since this gas is now trapped inside of the home. Most homeowners are unaware of the radon gas levels in their home and a very high percentage of homes in Northern Illinois need to be repaired. If you are a Real Estate Agent, you know that radon issues often occur after a purchase and sale agreement has been signed and before the closing. This frequently is a time when the schedule is tight and all parties are anxious to know about anything that might hold up the closing. And, since radon is a safety issue, it is much more likely to require resolution before the closing as opposed to simply an allowance at closing.
