"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 were very happy with the crew who worked in our home. Very professional. Prepared the site so we could not tell they had even been in our home. Testing following the job indicated that the radon gas was leaving our home. Our radon level went from 12 to 0."

"I had a great experience with this company. Doug did a fantastic job installing our radon mitigation system. He went above and beyond and sealed up some cracks in the basement concrete as well and explained how everything worked. I requested a quote only 3 days ago and it is already installed!"

"My existing window well had pulled back from the homes foundation over the past 20 years, allowing water and sediment to enter the well. Sediment would plug the drain causing water to build up and create an aquarium in the window well. You pass waterproofing installed a new window well and securely fastened it to the cement foundation. They carefully removed the previous window well and took care not to brutalize the surrounding landscape. Completely satisfied with their work"

"I had a hard time contacting this company at first but when they finally responded, the service was great. Chuck met with me and explained what he thought would work best for the crawlspace in our new home. We originally wanted to install drain tile to avoid any possible water seepage in the future but he told us it wasn't necessary. Unlike PermaSeal who tried to sell us everything under their roof! Buyer beware of PermaSeal! Anyway, Chuck offered to provide a payment plan since we couldn't afford it all in one lump sum. We had a few issues at the beginning with things unrelated to them but Chuck was very responsive and advised us regarding some issues with our village permit. Even though we called and e-mailed him several times in one day, he maintained his great customer service. We finally scheduled an appointment and then had to re-schedule which they accommodated. The day they showed up, they came a bit late but Chuck sent a message letting us know. He showed up to check out the installation as well and warn us of the strong smell of the foam to see if we wanted to leave the house. We stayed but the foam smell was very strong for a few weeks and even up to today, we have not used it yet due to the smell. We may not end up using the crawlspace for storage as originally planned because we've noticed there's still a lot of insects getting through there since we left the entrance open for the smell to dissipate. Well, the crawlspace looks good and we are very happy that they installed a light switch by the entrance and a bulb in the middle so we could see the entire space if we want to go in there. We also got excited when Chuck mentioned they would do a radon test to show us the difference with the insulation. This has not been done yet but I hope they still come out and do it. I really enjoyed working with Chuck. He is a great guy and I highly recommend using this company. Stay away from PermaSeal! I say this because they tried to take advantage of us prior to us contacting this company."

FAQs for radon gas abatement projects in Wilmington, 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.
