What affects air sealing cost in New Brunswick

  • 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 New Brunswick can push prices 10–15% higher.

Rebates & tax credits

Most New Brunswick homeowners cut their out-of-pocket cost with the federal 25C tax credit (30% of materials, up to $1,200/year) and NJ state and utility rebates.
