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. read more

I recently had VSI install a radon mitigation system in our basement, and I gotta give a big shout-out to Jackson. Originally we were scheduled for install a month out and asked if anyone had cancelled to get it done sooner and sure enough they were able to come a couple of days later. Install went smooth, Jackson was super helpful and overall, just an all-around nice experience. They walked my spouse and I through the whole process, answered all my random questions, and made sure we felt comfortable with everything. If you're looking to get a radon system installed, definitely hit these guys up and ask for Jackson. You'll be in good hands! read more

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. read more

Perfect business. They performed beyond expectation with outstanding, clean and professional results.

I did a DIY radon test and the results came back above the limit. I went to Homeadvisor and got an idea of the average cost to install a mitigation system. VPI was super quick in response and i had their quote same day. It fell in line with expectations so I went with them, also by reputation. We scheduled an install within the week and they arrived on time and were done in a few hours. They explained how the system was to work. I have a new test going and will see the results in a few months. Good job so far! read more

Guy and his partner did a great job installing our radon removal system at a competitive price! They kept the job site clean, the installation was well thought through and they communicated well throughout the job. The ideal exhaust placement was unfortunately right where we had a significant foundation repair done. With that in mind, Guy went out of his way to make a more complicated run to exhaust it in a more preferable area while keeping the installation looking clean. Highly recommended! read more

I used this company when selling our home recently----the person they sent walked through the basement and started with...'that will be an up charge" then as he walked further 'that will be an up charge'....by this time l just about had it with this character. I sold the home ....but the future buyer was in touch with this company and it cost me an extra 5K to sell the home. And the new buyer never had the radon mediation placed in the home....l was told this is common just to get used to this kind of behavior if you plan on selling your home....everyone wants a piece of the pie! read more

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. read more

VSI was very responsive and took care of my radon mitigation job in a way that didn't look bad. Happy to now live in a safer home!

VSI is the real deal. Like others have said. Their quote online was the exact price I paid. They treated my new home like it was theirs. Walkway runners, booties, and very professional. I had a professional inspection that said the levels were in the 6s. I bought a Corentium monitor and retested several times over the two months and it was pretty spot on. I just had the new system installed and my long term average is now .3 I was thinking it would still be in the 3s but .3 is a great reduction. I would highly recommend them. read more

VSI is the real deal. After testing my house & finding levels too high, I started searching (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. 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! read more

We had VSI work on our basement back in August. They installed a fan and sealed our sump pump which had a new $1200 back up sump pump put in months earlier. This spring our power went out for the first time since the back up pump was put in and it didn't go on. We had flooding and thousands of dollars worth of damage. When we had the plumber out to fix the back up, he told us the rod with the float was bent. So either the other plumber who installed the new pump bent it, or VSI did when they sealed the sump. If you have them out, be sure to test your sump before they leave. We sure wish we had. read more

VSI Radon Reduction - Environmental Abatement Near Me - Ingleside, Illinois

They installed system before I bought the house as inspection showed high levels of radon. Months later I was doing something in crawl space and found out that they removed all insulation on their pipe's way and never install it back. System itself looks ok. Installation quality is poor as you need to finish it by yourself. read more

Very responsive, up front pricing, and easy to work with! They were very respectful of my home, wore shoe covers, etc. Am extremely happy!

The guys at VSI are true professionals. My first call was late on a Friday afternoon. Kevin went through the quote process over the phone, gave me a very competitive price verbally and followed up with a written quote within 30 minutes. Since then, I've had to call in a few times due to scheduling issues on my side. Every time I called they answered within a couple of rings, the person was able to pull up my information quickly and I could have a productive discussion. I haven't even had the work done yet, but based on how easy they have made the process, I felt compelled to write a review. I'm sure many people are having to do radon remediation as part of a home sale when you have a long punch list. VSI helped me take care one of the most important things on the list with minimal effort on my side. I wish all contractors were half as good as VSI. read more

I was quoted $1750 on the phone. I had to apply permit by myself. On the day job is scheduled, they checked crawl space and said I gave wrong size, which I gave the room size on top of crawl space but there is actually another room. They wanted $200 more. I agreed it as I assume that is extra work. Once job is completed, I found out the extra work is to roll more plastic to cover the area. I complained extra charge is too high and no clear price quote was given at proposal. The owner started screaming on the phone that if I don't pay extra, they will rip the system off and repeatedly gave F-word. I had never dealt with contractors been so rude and tricky on pricing. They could come out and measure and give exact quote, instead of up-charging me at job site when I have no choice. read more

Just had my radon mitigation system installed by VSI. They did an exceptional job. Wore booties when ever in house. Installation is very professional. Even gave me a $50 cash discount. Get your radon checked, even if you have a passive system. Home kits are cheap. Then hire this company. read more

We purchased a new home and the radon levels came back high after testing. We hired VSI to install a radon mitigation system in our home. They installed a system that goes from our basement up through our garage. The work was done quickly and efficiently, and we are very pleased with the way they were able to position the pipe in our garage instead of being more visible on the outside of the house. We had the house re-tested about a week later and our levels are extremely low now. Highly recommend these guys! read more

We moved into a new home that we absolutely love, but found that the radon level in the basement was extremely high. VSI were extremely professional and not only removed the radon effectively, but their guarantee is that the radon level will continue to stay below 4, otherwise they will remediate it at their cost. They do a ton of houses on the North Shore. You really can't go wrong with this company. read more

My Radon unit was not working and was out of code. I called VSI and they came out right away to give me an estimate. We set a date and the work they did was fantastic. My unit is now up to code and working great. I would highly recommend them. They are very kind and very professional. Thanks again guys. read more

Needed a mitigation system after testing numbers were high. Keith was able to provide a quote over the phone, after asking a few specific questions regarding the home. Mitigation appt was scheduled quickly, crew arrived within the window provided. They were polite, respectful of property, and system was completely installed in 3 hours. Invoice was as quoted, no surprises. Only negative was the patching on cracks in the basement - a bit sloppy. read more

Contacted VSI Radon for a 2nd opinion. I was connected with Mike who was very courteous and professional. After discussing my issue with him, Mike was very helpful and took the time to give his recommendation and honest opinion. 5 stars to Mike and VSI Radon Reduction! read more

This company was recommended by my mother's real estate agent. Parents home was built in 1867, has field stone and concrete basement with additional dirt floor crawl spaces. Radon level high in basement but not in living spaces. (basement is not a living space, nor suitable for occupancy). The technicians came out, treated my mother's home respectfully and did a thorough examination of the space. I received a very complete report in a very timely manner. The location is not one in which you can "depressurize" I would recommend them to anyone needing an evaluation. read more

We contacted VSI needing a radon remediation pretty quick in order to meet a closing deadline. They met that deadline. They were so easy to work with, polite and courteous. They were a breath of fresh air. They did a great job and guarantee their work. You can't ask for much more. I highly recommend them. read more
