What affects air sealing cost in Big Bar
- Project size and access: larger projects cost more in total but less per unit. Hard access (steep roofs, low crawl space) adds labor.
- Final R-value or thickness: R-49 attics cost more than R-30, but qualify for higher rebates.
- Removal of old insulation: contaminated or damaged material needs to come out first.
- Air sealing scope: bundling air sealing with insulation is cheaper than two separate visits.
- Local demand: peak winter and summer months in Big Bar can push prices 10–15% higher.
Rebates & tax credits
The federal 25C tax credit ended for insulation placed in service after December 31, 2025, so new Big Bar projects don't qualify. Check current CA state and utility rebates — availability and terms vary by program.
