An attic insulation quote should specify the R-value being installed, since that number — not just "more insulation" — determines whether it will meaningfully affect your energy bills.
What to look for
- Current R-value versus target R-value — a good quote assesses what you have before recommending an amount to add.
- Material type — blown-in cellulose, fiberglass batts, and spray foam differ in cost and performance.
- Air sealing included — insulation without sealing air leaks first is less effective than either done alone.
- Attic ventilation — adding insulation without maintaining proper airflow can cause moisture problems.
