Recent work
Real jobs from across central Indiana. Before, after, and current.
Built by a firefighter. Run as a family business.
Justin Holliday spent years in the fire service before starting Holliday Insulation. That background shows up in every job — fire-rated materials, code-grade installs, and safety treated as table stakes rather than an upsell. Greg Hochstedler runs sales and customer relationships day-to-day, and the rest of the team is family. When you call us, you’re calling the people doing the work.
