Sustainergy Cooperative

About

Sustainergy Cooperative operates as a worker-owned solar and insulation company serving Cincinnati and the greater Ohio region. The business combines two complementary services—residential and commercial solar installation alongside comprehensive insulation work—under one operation, making it the only company in the Columbus and greater Cincinnati area offering both specialties together. On the insulation side, Sustainergy handles attic insulation, wall insulation, and crawl space insulation, along with air sealing in attics, basements, and crawl spaces. The company also provides crawl space encapsulation to address energy loss, moisture intrusion, and pest concerns. Insulation removal and replacement services round out their offerings for homeowners upgrading to new systems. The cooperative structure shapes how Sustainergy operates. Employees have the opportunity to become worker-owners, which the company states creates better quality service since employee success ties directly to customer outcomes. Customer reviews consistently highlight professionalism, thoroughness, and attention to cleanup. One customer noted the crew left their home cleaner than when they arrived after a basement insulation and sealing project. Another reported immediate results and friendly service. With a 4.9-star rating across 215 reviews, the business offers free assessments to homeowners interested in evaluating their energy efficiency needs. The company's approach emphasizes finding low-cost, high-impact solutions that deliver fast results, positioning insulation and solar together as complementary investments for reducing energy bills and carbon emissions.
