"Schan did a great job, very professional. He came out to see what the job was before he gave me a quote. I have a huge crawl space which took some time but he stuck with it to finish it in one day. Now I can breathe easier knowing it's taking care of right. I highly recommend Clean Air Radon Systems."

"We had a radon remediation installed by them in 2021. We've had to replace the fan 2x already- whereas the expected lifetime of a fan is 8-10 years."

"The guys came out within a day or two of my initial call and spent quite a bit of time explaining what they would do. They were patient and seemed very knowledgeable. Their solution involved routing the exhaust through the garage and garage attic and out the roof, which would be much more attractive and less subject to weather extremes than routing the exhaust pipe along the exterior of the house. After I gave them the go ahead, they were able to schedule the work within 1-2 weeks. They arrived on time and were very efficient, finishing a little earlier than I had expected. In addition to the radon remediation they patched a foundation crack for considerably less money than companies that specialize in foundation repair."

"Great. Excellent workmanship. We are happy with the result. One problem. We wanted the exterior vent housing and exhaust pipe painted to match our siding. Dupage Radon Contractors agreed to do this if we supplied the paint. Which we did. When I asked how much paint and primer to purchase I was told 2 gallons of each. This seemed excessive but I did as told. Total cost: $116 (paint) + $100 (primer) = $216. I now have almost 2 full gallons of unneeded paint and primer. 1 - 2 quarts of each would have been more than enough."

"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."

FAQs for radon gas abatement projects in La Grange, 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.
