Our experience with Green Stone Energy was outstanding. The first visit involved identifying the energy-saving opportunities that our home presented. We discussed those opportunities and I learned why and how the required work would be done. The second visit involved doing the actual work, which took half a day and was completed by two outstanding workers who impressed me with their expertise and diligence in getting the work done. I observed them carefully and was impressed with their professionalism and attention to detail. They were very respectful in terms of keeping our home clean even as they dealt with installing the attic insulation. I give Green Stone Energy my highest recommendation and do so without the slightest reservation. In an era when it is difficult to find truly trustworthy companies, Green Stone Energy was a very welcome surprise, and we couldn't be happier with the results.
