Drill & Fill

Springfield Insulation's drill and fill service is an ideal solution for existing homes that have little or no insulation inside their exterior walls. By carefully drilling small access holes and filling the wall cavities with high-performance insulation, we can significantly improve your home's comfort and energy efficiency without major renovations. Since an estimated 20–25% of a home's energy loss occurs through exterior wall assemblies—especially older, leaky walls—drill and fill insulation helps reduce drafts, lower energy costs, and create a more consistent indoor temperature year-round while preserving your home's existing finishes.
