Get matched with top radon gas abatement pros in Sycamore, IL

"Radon levels went from about 12 to hovering between 0.4 and 0.1 after about 24 hours. Great work done quick and done well."

"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."

"Radon inspection was the job"

"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."

"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 on 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!"

"OK, but water was contaminated and no suggestions to improve it"

"Installed radon mitigation system in basement. Pros: 1) reduced overall radon levels by about 75% 2) they did the work in extreme cold temps 3) done in about 4 hours Cons: 1) They arrived late (although they did call to let me know) 2) they did not wear boot covers or put down any floor protector when walking on my carpet 3) they set dirty toolboxes and caulk guns directly on carpet 4) exhaust pipe is too close to roof peak and can be seen from street view of house Overall, good job. I can live with seeing the pipe from the street. I would recommend based on the overall work."

"We needed a home inspection for a property in Chana IL.  This property is fenced and required the seller to to open the gates for us.  After I initially made an appointment with Mark to inspect it we were informed the seller could not be there and needed to change it to a Saturday.  Mark was able to find a way to fit us in.  He showed up early and was prepared to go to work right away.  Throughout the thorough inspection Mark pointed out anything of concern and explained what the issue was and what corrective action would need to be taken.  This was an older farm home and had more items that needed to be serviced than I originally thought.  Our inspection ended up taking much longer than expected due to type of home and some buildings on the property and Mark did not rush the inspection at all.  Anything we wanted to take a look at he was willing to give his opinion, take digital photos, and note in the comprehensive report we received via email.  We did have radon and mold inspections performed as well and the equipment he used was professional and had recent calibration.  With the depth of the inspection we have a good idea what we are up against with this home and it will help in asking the seller to provide a repair credit.  We would definitely recommend Mark Connely from Prospector to anyone.  We had just recently had an inspection done on another home and the inspector was slightly less expensive but did not document nearly as well or put anywhere near the effort into the inspection that Mark provided.  The saying you get what you pay for applies here and a home inspection is no place to cut a corner.  Hire Mark!"

"I was concerned with the other contractors we talked to because they required holes to be drilled in our basement concrete floor as well as pvc pipes being run all over our basement.  But with this system, the suction pipe went through our existing sump cover.  So we ended up with no dusty mess and no ugly pvc pipes on our home exterior because the fan sits in the interior. <br /> <br /> We were extremely satisfied with the solution - the radon levels are very low now - which is important because our kids play in the basement a lot."
