"Rogelio and the team were excellent and very professional. They were able to make it out in one day and complete the asbestos removal within a few hours. Every step of the process was explained to me first and I was given a chance to safely check on the progress along the way. Cost was very reasonable."

"I've used Domicile Consulting for several homes, after initially finding the company on Angie's List. Dan Cullen is exceptionally knowledgeable, objective and insightful. Prices are reasonable and well worth the investment. Dan takes copious pictures and compiles them in a handy report with recommendations. Highly recommended."

"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 Detection and Reduction questions, answered by experts

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

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

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

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.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.
