We chose Envirotech to do our insulation & baffle install in our attic because they were mid-range in price compared to others and Mark was upfront about what we needed and didn't try to oversell us. I am so glad we went with Envirotech! Very professional crew, cleaned up before they left. I was also glad to know how well he treats his employees. We noticed a difference in temperature upstairs immediately. Should we have another need for insulation I will definitely be calling on them again.
