"We hired Gardner Environmental Services to install a radon mitigation system in our home. Due to our finished basement and high levels of radon, we were told by other companies that a successful mitigation would be a challenging job. The team at Gardner was knowledgeable, professional, and did a wonderful job. They gave us different options and talked to us through the process. Our radon levels were originally around 18 and with the mitigation system, they were brought down to below 1 on our home reader. We now have peace of mind knowing that our home is safe for our family."

"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

"This company is great to work with. They did some mold testing on parents’ home and did excellent work. They also did some work on my home. They replaced a water heater and bathroom fans. He was easy to get a hold of, personable and come over right away."

"If you want the job done quickly and done right, Safe Haven Radon is it. On time for quote appointment and later scheduled work. Easily came up with a plan to mitigate the whole basement with one fan. VS another company wanted to install 2 fans which would only cover half the basement and we could â wait and see if more work needed to be done.â Safe Haven Radon was the only company that wanted to make sure the radon levels in the WHOLE house would be close to zero. They also guaranteed that once the work was done radon levels would be below 1. Another company told me â you donâ t live in the kitchen, so we donâ t need to test there.â Why would we do all this work and NOT make sure the whole house was safe? Safe Haven Radon did the work in a few days, made sure all the pipes were in unfinished areas, and left areas impeccably clean. He also made sure that the outside fan and pipes were in an area that made sense for the house, near other pipes and A/C, even though it meant doing a little extra inside work. These guys were the best!"

"Scheduling was easy, and the staff were always quick to respond when I needed to contact them if I had to leave a message, I received a call back in 15 minutes or less. The inspection was done by Chuck, who was willing to work with me to stay within my budget. He spoke honestly about what he saw, and gave reliable advice. He turned around a slick report which detailed every issue and the implications. I will definitely use this service in the future."

"We were in the inspection process of buying a house, and Greg agreed to do an estimate, even though we knew the crawlspace might have been a deal breaker for us since it was in pretty bad shape.  The home inspector suggested a vapor barrier.  I searched Angie's list and found Greg and his crew.  
Another local company I called would not come out to do an estimate since it was only a home inspection, and we weren't 100% sure we were going to buy the house, let alone complete the work after the purchase.
Upon talking with Greg the first time, I had a feeling that he was going to do a good job and be easy to work with.  He was very straight forward and truthful.
The crawlspace was a dirt floor, and probably hadn't been touched in over 20 years.  It was dank, wet, full of bugs as evidenced by the webs and old traps.  It was also had the beginnings of some rather serious issues from the neglect.  The bones were good, but it was definitely time to dry it out and start over.  Originally, I was looking to get the sealed with concrete and Greg suggested a new material, a spray on material, to use instead.  He assured me it would be strong enough to be used for storage items.  It would also save us 4 inches of clearance over the concrete, which makes a difference in a crawl space.  I decided to go with it, even though it was a brand new method at the time for Greg and his team.
 We decided to move forward and buy the house and we also decided to hire Greg and team to help transform the space in to a working storage area.
I could not be more happy with the result.  Greg's team showed up and immediately got to work.  Even though the house was not being lived in at the time and other contractors were there, the entrance and work areas were covered in plastic which is good thing as the guys coming out of the crawl were covered in mud.  I was surprised out how swiftly the crew got to work.  They got the job done quickly, and were extremely professional throughout the entire process.
After a fantastically wet spring, it turns out that a foundation crack was causing some very minor seepage from the outside after all of the work was complete.  Other houses in the area had their entire basements and crawls completely flooded.  Greg came back and sealed a very small crack free of charge to finish up the job.
I wish I had more crawlspaces to give Greg and his team more work.  I will definitely use them again should the need arise."

"A lot more to discuss about this than I would like. Drain tile construction seems fine, which is the most important part of this project by far! We will learn more upon a rainy season in the fall or spring. Demo was not as clean as we would have liked. We have steel studs in basement, so they pushed out walls to put drains to window wells behind electrical conduit for outlets. This ripped the drywall off of studs and pulled framing away from windows. We had to rerun electricity around the new drains and do some repairs because of this. If we had wood studs, we do not think that they would not have been able to cause as much damage, so this shortcut cost us some work. There is also a small dent in our ceiling on the main floor from when they were carrying materials. Dust was everywhere. They left the door to the basement open during demo and construction so dust was all over our main floor. Also, they mixed the concrete in our garage, so everything we move out of the basement to avoid dust is now covered in concrete dust. This is very difficult to remove since mixing with water will form more concrete. They asked what we need from them to fix this, but we do not see a good solution other than wiping down each individual item ourselves. It's a lot of work we spent a lot of time trying to avoid by following Alex's recommendations. There was a miscommunication and Reliable Basements did not put the new sump pump in, plus the check valves were put 2 inches from the lid of the sump pit leaving the pit inaccessible to us. After several attempts at communicating with them, they responded and replaced it and fixed the check valve placement in a timely manner. They missed a crack in the foundation, but were quick to come out and fill it for the same price they offered during the drain tile installation."

"Chuck asked all the right questions before giving a quote and gave us multiple options to address the problem leaks. His serviceman, Josh, was courteous and professional, clean and efficient. They filled two basement cracks with the injection sealant and we are pleased with the results. I would use them again.

FAQs for radon gas abatement projects in Woodstock, 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.
