Great place to do business. Very professionally handled from initial phone call to installation. Excellent installers. Explained everything and left the work area clean.

Fantastic company. Talking to a coworker who needs radon reduction, and I recommended VSI. Got me to thinking I never reviewed them so here I am. Took our radon reading from 16 to .8 They installed the mitigation system in 2009, and other than needing a new fan after 10 years, it has run perfectly. Zero issues. When I did call for service I seem to recall it was done within 48 hours. The overall system is very simply and I don't even notice it. They core a few opening into your slab, plumb the piping to the outside of your house, and turn on the fan. My fan is in my garage attic. When I am in the attic I do not hear the fan. It is silent. I cannot recommend them enough.

Let me start with saying that the radon level at my house did go down and that’s why I gave 2 stars. However, one of the guys that installed the system was extremely unprofessional. He didn’t wear shoe covers in my house, walked around and left dirt everywhere including the kitchen (he asked to use the microwave), and I found hand prints all over the walls in the working area. When we had a call afterwards regarding a banking issue, I got the rudest customer service ever. Would recommend to use other company for a better experience.

We had a Radon level's in 6's. The crew came in and installed a Radon mitigation system in the sub pump and crawl space... dropped our Randon numbers below 4.0 in a matter of days, allowing us to sell our property... Thanks for doing a professional Job.

VSI sent a great crew to install a radon remediation system. I was under a strict time crunch and they handled it with ease. Highly recommend.

Talked to Zack about the radon situation in our home over the phone and was amazingly surprised by the fact he wasn’t trying to sell me anything, but share his knowledge about the topic and also give his recommendations. I had hard time finding companies that don’t try to push their services just to make money, but actually provide sensible and thought out solutions. And listen to potential customers. A++ to VSI for doing that. And thank you Zack.

High recommend them for installing Radon Mitigation Systems, my basement had a level of about 29 and the new system brought it down to .6, their staff is also very knowledgeable! Once they placed the mitigation system into my home I asked them to walk me through and he explained everything perfectly in a way I can understand and feel safe that the system is working and is of upmost quality.

VSI was recommended for radon mitigation for home closing. Lead Technician Kevin was very informative, knowledgeable and pleasantly direct in his assessment and design. He along with Gage performed the two system installation. Excellent work habits while keeping us informed during the day. Office staff was prompt and courteous in setting up schedule and processing contracts. Thank you all!

I will recommend VSI Radon to everyone I know. We already had a passive system, and our levels were high. They came out and installed a fan and were very friendly and clean. I noticed that afterwards, our levels were still high. They came out no questions asked. They sent 2 guys who were very personable, friendly, clean, all the great things. They were passionate about resolving the issue. At no cost (under the fans warranty), they made additional repairs and our radon levels are now from a 9.2 to a .8. I've received a call to check in on our system and how we are doing. A great company, with good morals!

VSI is the real deal. After testing my house & finding levels too high, I started searching for mitigation (Angie, HomeAdvisor, Yelp, etc.). VSI was on every list, their website is extremely informative, and the founder (Mr. Volsted) even created courses @ U of Chicago about radon – some reputation! Then my personal trainer showed me a picture of her radon mitigation system and there was the VSI sticker. So I called, Kevin answered quickly, and after several questions he gave me a quote over the phone & sent emailed it within the hour. A week later Guy and his crew came and did an exceptional job installing the system. Very professional work - respectful of property, wore booties inside, vacuum attachment to concrete drills so minimal dust, and cleaned up everywhere. Great color match on outside piping. Guy even did a smoke test w/ pilot holes to demonstrate the suction beneath the basement floor. Guy gave detailed explanations & answered all my questions. I have a continuous monitoring system and even within a few hours radon levels have already dropped significantly. Very satisfied, highly recommended!
