"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."

"Tim was on time and finished early. Nice, neat install. I can't be absolutely sure how accurate my radon detector is but before the install the highest short- term reading I saw was 7.94. After the install I haven't gone over 2 and usually is 1.5 or lower."

"The inspector and the quality of the inspection report were absolutely professional. The work was completed in a timely fashion and the inspector was available to answer questions after the report was provided. We did have some unnecessary drama with the subcontractor that was to do the radon test that Domicile arranged, which is the only reason I gave them a B for professionalism. We ended up using another company to do the radon test, but the drama caused an unnecessary delay. I would hire Domicile again as I have had prior experiences with them and their work has always been of the best quality."

"We used Radon Testers for testing in our home in Chicago. I was very pleased with the responsiveness and professionalism of the company. They are also very technology enabled - you can make appointments online, you will receive an auto text when they are on the phone and test results are sent in .pdf form via email. Great stuff! <br />"

"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."

"My fiancé and I needed a home inspection and Radon testing for two houses. We are first time buyers so Mike was very thorough on the inspection and took the time out to teach us everything to look for. The pricing was expensive compared to other providers, but I thought he was worth it. We ended up going with a different house and he dropped the price for a repeat customer"

"Dave Masa was first recommended by our realtor. I then had a meeting with an attorney who also offered his name as the go to guy for this type of work. I then checked Angie's list and found that others also thought highly of the work performed by Radon Reduction Systems. We received both a verbal and detailed written bid for an external system that was accepted. I was particularily impressed with his written promise that his work would be honored (warrantied) for five years and would extend to the new home owner following the home sale. <br /> A few days after Dave's inspection, I asked him to return to our home to review the possibility of installing an interior system. Not only did we he believe the interior system would be feasible, he indicated that the price would not change. We're delighted with the result. It is easy to describe the work performed. It was efficient, timely, and professional in quality. Care was taken to place the piping in areas that did not interfere with daily living. The work was completed (by 2 people) in approximately 4 1/2 hrs. <br />"

FAQs for radon gas abatement projects in Winnetka, 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.
