Efficiency Group

Efficiency Group is a local Insulation contractor helping Detroit-area homeowners and businesses improve comfort and cut energy bills. They can assess your attic, walls, and crawl space, then recommend the right mix of air sealing, blown-in cellulose, and spray foam to reach Michigan’s target R-values and reduce drafts. Ask for a free in-home energy assessment with a blower-door test, a written scope detailing materials and R-values, timeline and cleanup plan, and proof of licensing, insurance, and permit handling. Before booking, request a line-item estimate that factors in DTE Energy/Consumers Energy rebates, financing options, and a transferable warranty so you understand total cost, payback, and long-term coverage.
