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.
