What Our Client’s Say

Great Environmental saved our sanity. For the longest time, we thought we had a mold issue in our home. An unusual smell greeted us every time we walked in the door. John Gezik and Great Environmental came to the rescue. With the set up of his advanced high-tech Indoor Air Quality testing equipment, he determined we had no trace of "live" mold. Fear put to rest. The source of the smell was determined to be a combination of other elements in our home that was easily rectified. Great Environmental was worth the cost of service for my family's health, well-being, and peace of mind.

Great Environmental, Inc. came out to test my home for mold. John was most informative. His customer service was A+.
He answered my questions and delivered the lab results when promised. I would not hesitate to use his company again should the need arise.

Thank you, Great Environmental, for resolving an asbestos issue and saving the day!  We were 1 week away from closing and explained the situation to John and he had his team out to fix the issue within days (on holiday weekend too)! Customer service was excellent and I would recommend Great Environmental to anyone looking for asbestos or mold remediation. Realtors should save this company in their address book ASAP. Sellers, buyers, lenders, everyone involved in the transaction were very happy with their services.

When I discovered a mold problem in a rental house, I called Great Environmental to assess the problem. They used state of the art equipment, reviewed the results with me and took the time to explain the results to the tenant living in the house. They designed a plan to fix the issue, and it worked well. They showed up promptly for appointments, and they answered all of my questions. Their service is not inexpensive, but it was worth it to fix the problem. I'd have no hesitation about using them again.

I had a great experience overall. Great Environmental came through in a tough situation for me. John took the time to understand my situation and the urgency it called for. Safety, knowledge, honesty, integrity are what I look for in a contractor. John was able to deliver in all of these areas. Citing a conflict of interest, John had to decline the remediation of black mold which was found in my bathroom. Instead, John worked directly with my mold remediation contractor and provided a comprehensive set of protocols to ensure proper safety, containment, ventilation, abatement and even covered how to get rid of the waste to name a few. I recommend Great Environmental for these reasons.


John was amazing. He is very professional, answered all of our questions and was very reassuring. I would highly recommend his services!

I had the pleasure of using Great Environmental's services this week. I had previously called 3 other companies and had been told I would need to wait a minimum of 3-4 days. Hiring a company from halfway across the country and no previous personal contact with them, needless to say, I was initially concerned. However, everything was clearly communicated and completed as stated. I was more than satisfied with there services and would recommend Great Environmental to anyone.
