"I highly recommend Midwest Radon Services and I am relieved that the system installed was effective. Price was fair and competitive; all work was thoroughly and patiently explained with no pressure. Work was neatly and expertly finished. Suction under the basement slab was tested by measuring into a hole drilled then patched at the other side of the basement and turned out to be extremely good. The system continues to work extremely well with a sight verifiable U-tube monometer on the exhaust system continually monitoring. In addition, over 18 days since installation, the long term Radon readings, on two different digital testers purchased from Amazon, went way down from a maximum of 4.5, to a range of 0.83 - 0.6 during the time when the furnace was being used which is also a time that Radon readings tend to peak."

"Tom and Josh arrived on the day and time promised. They were both very polite, professional and worked extremely well together. They explained exactly what they were doing and why they were doing it! They installed the radon Mitigation system and went above and beyond expectations. They cleaned up after themselves. After the job was complete, it looks like it has always been here. What more can you ask? I will definitely recommend DC Mitigation for anyone who needs this service!"

"A++ service. Mike performed an excellent job testing a house we are in the process of purchasing in addition to the Radon testing. We found him to be personable, straight forward, detailed, honest and informative. Each area of concern, Mike provided clear details for the rating given which included pictures with arrows pointing to the exact location. Overall process went smoothly. Would gladly hire again in the future and/or provide as a reference."

"Working with BRT on our home inspection and radon test was incredibly easy and very competitively priced. Dave was very easy to get a hold of and was able to schedule us quickly. He is very knowledgeable about homes and construction in general. He not only showed me certain issues with the house but also explained which items I could fix myself and where to buy the parts. He differentiated the items that couldn't be "DIY-ed" and offered to provide (didn't push) contacts for these items. The best value with BRT is the fact that they can couple a radon test with their home inspection. Most home inspectors sub-contract their radon tests with different companies. This not only adds time to your inspection (cutting into your inspection review period) but also costs a lot more money (I quoted 5 different home inspectors and BRT was the most competitive). To top it all off, Dave is a personable guy who is very easy to get along with and has plenty of experiences to share. I would highly recommend Dave and BRT to anyone getting a home inspection (especially if you're getting a radon test too)."

"Daniel was very professional and the most thorough and experienced inspector I've ever met. He sent me a very detailed report for the 1500 sq ft condo, which could easily be transformed into a punch list of action items for the seller. In addition, he was very responsive to any questions and even sent me a list of recommended contractors when asked."

"This is the second time we've used Mr. Lisse. He was first recommended to us by our realtor as "the guy he would use if he were buying a new house". Jeff performs a very thorough inspection of every part of the house. He invites the prospective homebuyer to follow along throughout the whole process as he points out every high and low point of the property. He takes many pictures during the process and delivers an incredibly detailed report outlining all potential concerns, along with his recommendations on how to best go about remedying them. He also works closely with another company that provides radon testing services and can arrange for that service (at an additional charge) to take place concurrently with the inspection. <br /> <br />I believe we may have received a repeat customer discount of around $50, so the price quoted above may be lower than what might be expected for new clients, but no matter the price, this is the guy you want to check things out for you before you invest your savings in a new home. <br /> <br />Highly recommended."

FAQs for radon gas abatement projects in Northbrook, IL

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
