"I called John from Great Environmental after he was highly recommended from Brickkicker Home Inspection Svcs for mold testing. John came over same day as we were in the midst of contract negotiations and future buyer wanted results before signing. He was extremely knowledgeable and professional and easy to work with. His test results were thorough and easy to understand. I will pass his name along for sure!" - Meg M, Clarendon Hills IL

"Our realtor recommended Great Environmental to us when our inspector found signs of asbestos in the home we were purchasing. John promptly tested for us and immediately wrote up a proposal per our request. He was thorough and patient in answering every question we had along the way, and he was always available to us by e-mail, phone, and text. John and his team completed the project in one day, which allowed us to move in even earlier than anticipated. John was easy to work with, and we will certainly use Great Environmental if we ever have future issues. Thanks for the great service!" - Elizabeth P., Arlington Heights IL

I would recommend him to anyone in need of these types of servces!" - Deann S., Naperville IL

"After researchng at least three (3) companies, we decided on Great Environmental based on their presentation, their service experience and their references.  We later found that a personal friend knew the company owner and spoke highly of him.
Our dealings had to do with water in the basement and resulting mold.  The response was fast, the estimate was derived after mutual conversation (none if this well, you have to do this and it will cost you xxx). The work was performed most efficiently, with air samples done before and after.  We are most pleased with the very reasonable cost and the performance of Great Environmental." - Tom P., Aurora IL

"Mr Gezik came to my home to inspect for mold. We have an older home that has a basement with a storm door egress. He was honest, and I felt very comfortable with his assesment. He took the time to inspect, and inform me of mold, and it's growing habits. I am very pleased to say the least! How refreshing to find someone who is honest and straight forward with you and not trying to rip you off!. I would recommend this company, very highly in fact. I looked on BBB has an A+ rating! I got lucky and my concerns were put to ease that we do not have a mold problem...but, I certainly will use his buisness in the future if I ever do...or know someone who has a problem with mold or is concerned! Thank you so much!!!" - Jennifer M., Channahon IL

"When I found out how bad my asbestos problem was, I panicked. I was ready to hire the first company at whatever cost. The first bid came my way, my jaw dropped! Calls to other places were not much better. Great Environmental was the last call I made, it should have been my first! I talked to John, and a few days later he was at my house evaluating my situation. He was very thorough with his inspection, and gave me a quote. Great Environmental saved me a lot of money, and did an AWESOME job! Even after the job was completed, John was available to answer the few remaining questions I had. I would recommend Great Environmental to anyone and everyone.‎‎"- Twanzilla

"Great Environmental was highly recommended by our home inspector for our new construction home.  We had a prior minor mold issue in our new home and we wanted to be confident and sure that there were no further signs of mold present in our home.  After the results came back with excellent results that there are no signifant signs of mold, my wife and I can rest easily assured that our family is safe in our new home Great Environmental was easy to work with, and was able to quickly schedule testing at our home very quickly.
We would highly recommend them."- Dave B., Downers Grove IL

"Great Environmental was actually chosen by a contractor who was bidding on HVAC work in our building and wanted to test for potential asbestos.  John Gezik arrived on time and was extremely informative in his analysis of our building.  He was patient and understanding of my questions and great to work with.  He emailed us the test results as soon as they were available (on a Sunday, actually) and we were of course thrilled to know the test areas were free of asbestos.  I highly reccommend Great Environmental."- Brandon S., Chicage IL

"John did a fantastic job at answering my questions, conducting the visual tests, and obtaining 1 sample to send into the lab. Even on a hot August day, climbing into an attic and poking around looking for mold.. he didn't complain. We received our lab results in 1 day (ahead of schedule). I would use John again in the case we ever need inquiring about mold. In addition, John did a great job going above and beyond our expectations. Go John! He is very customer service oriented."- Kathy N., Naderville IL

"Two days after closing on our first home, we discovered that some duct work in our basement was lined with asbestos paper.  Hearing the dreaded "a-word," I panicked! As a mom to a 9 month old, having a safe and clean environment for my family is of the utmost importance and the thought of having hazardous material inside of our home was terrifying.  I called John at Great Environmental and he instantly put my mind at ease.  Within 24 hours, John was at my front door to assess the situation. He performed a thorough investigation of the house to verify that the asbestos was contained just to the basement.  The other two abatement specialists I met were at my home for less than 10 minutes. John was here for over an hour and must have looked inside every vent and duct to ensure there was no presence of asbestos elsewhere in the house. 
Knowing my intent to get everything removed as quickly as possible, John arranged for his crew to come out on the weekend to remove the asbestos which was amazing! And, he didn't just send workers to our house to blindly take care of the job. John drove up to Glen Ellyn at 7:30 AM on a Saturday to kick off the project with his crew and explain to us in detail exactly what was going to occur.  At the conclusion of the project, John came by once again to personally inspect the asbestos removal and confirm that the area was clean.  I have never seen such attentive, hands on customer service from a contractor.  I was seriously blown away. John is what makes Great Environmental GREAT!  His customer service is outstanding.  I know he's a busy, busy guy and he made me feel like I was his only customer.  He was extremely patient with all of my questions (and I had a lot!), explained things in a way that was easy to understand, and did it all with a smile and sense of humor.  At the end of the job, I felt like I could have given him a hug!  He and his team did a fantastic job and at I felt 100% confident that I could finally start our life in our new home asbestos-free!  I would have no hesitation recommending Great Environmental to anyone."- Sara D., Glen Ellyn IL

"I had 50 feet or less of asbestos insulation on heating pipes in my 90-year-old home and wanted it removed in anticipation of selling the house. It was not a big job and I wanted to support a local removal company. I went in search on the Internet and found a family owned company called Great Environmental. I placed a call and spoke with John Gezik, the president of the company, who agreed to come to the house and give me an estimate. Upon arrival John walked through the entire house to make sure I had identified all of the areas where pipe insulation had to be removed. John thoroughly explained to me how the removal would be done. He e-mailed me what I considered to be a reasonable quote within 24 hours. I agreed to have Great Environmental do the work because of how knowledgeable, honest and caring John was, let alone the time he spent with me answering my questions. The day of removal the crew arrived on time and John was there to make sure they knew exactly what had to be done. Once the crew was done John returned to make sure I was satisfied that everything was done as promised and met his high standards. I could not be happier with the workmanship, professionalism or all of John’s efforts throughout this process. If you have an asbestos concern in your home I would not hesitate to give John a call. He's a great guy to work with."- Bob S., Joliet IL

John explained everything that needed to be done on the front end, and I had no “surprises”. They did what they said they would do, and everything looked great upon completion. For the service they provided and the hassle-free experience, I got a great deal! Highly recommended!"- Evgeni, Northbrook IL

"I found Great Environmental on Google Maps And read all the great reviews. Called John to discuss my options on tile removal as well as vermiculite removal. He talked to me as if we were lifetime friends, very professional. He suggested that I have the tile tested to make sure that it was asbestos even though he said I had only a 2% Chance that it wouldn't be. It came back negative and he saved me a bunch of expense. Awesome guy and highly recommended."- Jason., Riverside IL

"John Gezik (of Great Environmental) is very personable and great to work with. He communicates well and is responsive to questions and phone calls about the work. We worked into an agreeable timetable for the task of removing siding from our house on the second floor. His workers arrived on time on the scheduled start date and work was completed ahead of schedule. The work was done well and the clean-up of the yard/garden and other areas around the house was superb. Great Environmental used creative thinking in how to get the work done on our house that enabled them to come in with the lowest bid of the 4 companies we took bids from. They earned their VERY GOOD rating." - Don G. Glen Ellyn, IL

“I hired John Gezik, President of Great Environmental to handle mold remediation in our basement. Following home inspections, and after reviewing two other company's proposals, I was very surprised at the high cost associated with mold removal. Having two younger children at home, I was also concerned with the use of chemicals that the other companies were using to eliminate mold from our basement. However, Great Environmental, offered a chemical free alternative that was substantially less then its competitors.
John was my main point of contract throughout the process. John returned my calls and emails promptly, and thoroughly discussed the whole process with me in great detail. John and his crew showed up on time each day and completed the work two days sooner than what his competitors were offering. During the whole process, John's crew were very professional and courteous. After the work was completed, the basement was SPOTLESS! I was thoroughly impressed throughout all phases of the project. If you are considering mold remediation in your home, I would highly recommend Great Environmental.” - Craig B., Naderville IL

He took the time to explain everything to me. We emailed back and for and since I was out of state he came to the house to inspect the area and ended up meeting practically the entire family.

I took before and after pics and what a transformation. CALL TODAY!‎" - Mary, LaGrange Park IL

Your totally 'GREEN' process is 100% environmentally friendly and doesn't utilize any chemicals. Thank you for totally eliminating the pet odors, killing the mold in my attic and making suggestions for overall home health improvement. You made the process so easy and now I have the peace of mind I didn't believe was even possible!” -Michael H., Naderville IL

“After having our basement infested with asbestos fibers by a careless HVAC contractor, John was there to collect samples for analysis and offered us a quote for a cleanup. His quote was very competitive, and even if we chose to buy equipment and clean up the area ourselves, John was there for us throughout all this, we called him several times, and he always offered free and valuable advice. John is very knowledgeable on the subject and honest. We will hire him to remove some mold in the attic.” Marius D., Naderville IL
