Quality work. Quality people. Since 1972.
An unseen force with profound impact.
Galloway Insulation is a trusted insulation contractor with over 50 years of expertise in Greenville, SC and the Upstate, specializing in tailored, energy-efficient solutions for metal stud, wood stud, and steel frame construction, backed by unmatched honesty, reliability, and deep industry knowledge.
While insulation itself is hidden within the walls of a building, its impact is profound: creating more efficient, cost-effective spaces that benefit our customers. At Galloway Insulation, we work a bit of quiet magic each day. And just like insulation that’s done right—you may not see it, but you’ll feel the difference.
When people thrive, good things happen.
We do more than install insulation—we invest in people. By bringing good people together around meaningful work, we build lasting relationships grounded in trust, hard work, and integrity. Supporting and developing our team isn’t just important to us—it’s essential. Through encouragement, growth opportunities, and a culture that values each individual, we help our employees build confidence, discover their strengths, and reach their full potential.
Our Mission is to create strong foundations—both in buildings and in relationships—and to be a conduit for good people and good work. We accomplish this by building trust and respect with our customers and employees through unwavering integrity, honesty, and dependability.
