"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."

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"We called our vendor because the equipment was not working. When the service man came out said couldn't be fixed. Installed a newer model. Was not a little less expensive than we thought - but the serviceman & product performed superiorly so was more than worth what we paid."

"Work went fine. 9 months later when I could actually get down in crawl space I found that there were several areas where plastic was not taken to outside walls as was contracted. They cleaned up 25 years of other contractors leaving their trash behind and then left theirs' behind. The spray insulation cans were laying all over. Contract said mold was supposed to be re checked in a year but nobody has come back. I have called and talked to the owner 3 times and he told me he would be by. The fourth time my call was never returned. Always get several bids and get multiple referrals. <br /> <br />"

FAQs for radon gas abatement projects in Ottawa, 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.
