Cornerstone Contracting LLC

Cornerstone Contracting LLC operates as an insulation contractor serving Cleveland, Georgia and the surrounding communities. The business maintains a perfect 5.0-star rating across eight customer reviews, reflecting consistent homeowner satisfaction with their residential energy efficiency work. The company operates Monday through Friday from 8 AM to 5 PM, providing services focused on attic insulation, air sealing, and comprehensive weatherization projects for single-family homes.

The contractor distinguishes itself through active participation in multiple utility rebate programs, including the Georgia Power rebate initiative, HER Program, HEAR Program, and weatherization programs offered through Jackson EMC and the GEFA program. Their service menu extends beyond insulation to encompass duct sealing, water heater installation, combustion appliance testing, smart thermostat upgrades, and home performance diagnostics. This multi-faceted approach allows technicians to address envelope deficiencies that contribute to energy loss, rather than treating symptoms in isolation.

Customer reviews highlight specific technicians who delivered measurable results. Mike emerges as a primary contact who guided homeowners through rebate paperwork for both Georgia Power and state programs, responding to numerous questions via email throughout the process. Another reviewer describes a crew that sealed unfiltered air from entering a home during a whole house weatherization project, noting immediate comfort improvements and anticipated reductions in dust accumulation. A third customer recounts how the team addressed attic insulation and air sealing in a home that previously could not maintain 65 degrees despite heating settings, ultimately qualifying the homeowner for utility rebates.
