"The company communicates well. The sales representative Rich was helpful, knowledgeable and not pressuring. He followed up with us throughout the project. Their lead installer/ technician Isaac was on time, on task, and very respectful of us and our home. We purchased a solar attic exhaust fan, blown in insulation, and a multi layer blanket, the interior climate difference was instantly noticeable and our monthly energy bills have substantially reduced. We've all heard the term "cheap ain't good and good ain't cheap" , this applies to Great Lakes, but we have found their expertise and quality product to be an investment rather than a cost. I would highly recommend their services to anyone in need of insulating services."
