What a insulation costs in New York City
Price depends on which areas you insulate (attic, walls, basement) and how much air sealing is needed. Ask each company for a price per area and the R-value you end up with, so quotes are easy to compare.
That could cut your cost by up to $14,000 if you qualify. Most rebates have rules (income, your current heating, a registered contractor, approval before work starts).

Why insulation matters in New York City
In New York City, the average January low is -3°C (26°F), colder than 39% of the 123 cities we track. Sealing air leaks and topping up the attic usually pays back fastest here. Basement walls and rim joists are often the next biggest heat loss in older homes.
Most rebate programs pay only after an energy assessment, and some need one before the work too. Book it first.

- Ask for the R-value before and after for each area, and the material and depth they will install.
