"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."

Clients receive an on-site education about the property by our knowledgeable state certified inspectors. This gives clients the confidence they need to make this important decision the right decision.

"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."

Award-winning Service- AFFORDABLE, DEPENDABLE, EASY. Over 30 years experience installing 15,000+ radon systems. Highly rated on Google, BBB, Yelp, and Porch. Free, no obligation system design and bid. It's a solid price, not a phone bid that may increase on installation day. More fan options are available than from most competitors, to better match your home and situation. Being a bigger firm, allows volume materials purchasing, keeping prices VERY COMPETATIVE. Most systems install in one day. Full-time, trained office staff to answer your call, less phone tag. Systems are typically 100% guaranteed to lower the radon below 4.0 pCi/L and keep it there for at least 5 years. Saturday installation is available as are custom painted systems. Also, licensed electrical contractor. Residential, Commercial, Multi-family and Day Cares.

"Rubin and Brandon came out to install our system on 3/14. They were both on-time and professional throughout the installation. They worked quickly, were clean, did a great job explaining how it worked, and answered all of my questions. The system was competitively priced as well. I've worked with many contractors, and it's not common to get all of these from one company. My radon levels are close to 1/4 of what they were before within a week of the installation so I know it is working well."

Radon Detection and Reduction questions, answered by experts

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

Through air sampling devices and surface swabs in key areas of concern.

DIY radon detection is possible using over-the-counter test kits, but professional testing can provide more accurate assessments, especially in cases of high initial readings.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.
