What affects wall insulation cost in Old Saybrook
- 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 Old Saybrook can push prices 10–15% higher.
