Insulation cost ranges

Last updated from data: BLS OEWS May 2025 · PPI construction materials 2026-09

What this estimate can’t tell you. Roof pitch, an old house or code upgrades, tough access, permits, emergency or after-hours calls, and brand tier can push a real quote outside this range.

Wage coverage. BLS publishes this occupation in relatively few metro/nonmetro areas. Where your ZIP has no local wage, the calculator uses the U.S. OEWS average and says so.

Same estimating math as the calculator: hours × local (or national) OEWS wage × markup, plus materials. Open a job to run it on your ZIP.
