Insulation in New York: what to know
New York has cold, snowy winters and hot, humid summers, so homes work hard in both directions: heating from November to March and cooling through July and August. Much of the housing stock is older walk-ups, brownstones and pre-war co-ops, where aging pipes, radiators and wiring are common.
- Adding attic insulation and air sealing is one of the most effective ways to cut winter heating bills and reduce ice dams.
- Many older homes have little or no wall insulation, and blown-in insulation can be added without opening walls.
- Insulation helps in both seasons, keeping heat in during winter and out during summer.
How much does insulation cost?
- Attic insulation: $2,150 – $3,500
- Blown-in insulation: $3,250 – $7,550
- Air sealing: $650 – $2,500
