Detailed Profile

Koala Insulation of Greenville has operated from their Piedmont base for 20 years, building a diverse home services business that now encompasses insulation, roofing, and solar installation across the Upstate South Carolina market. Their expansion into solar represents a natural extension of their energy efficiency focus, and it gives them an integrated approach that many dedicated solar installers cannot offer: the ability to assess and improve a home's overall energy envelope before designing a solar system to meet the reduced load.

Their 4.9-star Google rating from 445 reviews is an impressive metric for a company operating in a market where solar adoption is still in its growth phase. Customer feedback consistently highlights professional installation crews, transparent pricing, and the practical advantage of bundling insulation upgrades with solar projects. That bundled approach often results in better overall energy savings than solar alone, because reducing a home's energy demand first means a smaller, more cost-effective solar system can cover a larger percentage of the remaining consumption.

The company serves homeowners across the Greenville, Spartanburg, and Anderson metropolitan areas, covering much of the I-85 corridor through Upstate South Carolina. Their familiarity with local building codes, permitting processes, and utility interconnection requirements across multiple jurisdictions is a practical advantage in a region where requirements can vary significantly from one county to the next.

Koala Insulation brings the kind of home performance expertise that purely solar-focused companies often lack. Their background in insulation means they understand thermal dynamics, air sealing, and building science principles that directly affect how a solar system should be designed and sized. Zero BBB complaints over the past three years reinforces a pattern of accountability and customer satisfaction across their full range of services.

With a composite score of 73.8 out of 100, Koala Insulation of Greenville holds the third-ranked position in South Carolina for 2026.
