What is different about attic insulation in New York
New York City operates its own construction codes and DOB filing process; a project that is a one-form permit upstate can require a licensed filing representative in the five boroughs.
Owner-builder: Homeowner permits allowed upstate; New York City is far more restrictive. Attic Insulation is one of the scopes a homeowner can more realistically permit themselves.
What drives the price
- Attic square footage and existing R-value
- Blown cellulose or fiberglass versus spray foam
- Air sealing of penetrations before insulating
- Attic access and headroom
- Removal of contaminated existing insulation
