Blown-in insulation for Staten Island homes
For most Staten Island homes, blown-in insulation on the attic floor is the fastest way to a warmer house. Dense-pack cellulose also fills closed walls through small holes.
Where it works
- Attic floors: loose fill over the ceiling, after we seal the gaps around pipes, wires, lights and the hatch.
- Closed frame walls: one small hole per bay, filled and patched.
- Side attics behind knee walls: in capes and colonials.
How a job goes
- We seal the attic floor and check for wiring and old insulation.
- We blow in insulation to the depth the attic needs, or dense-pack the walls.
- We patch the holes and clean up.
Rebates
Staten Island has National Grid gas and Con Edison electric. Most one- to four-family homes now go through NYSERDA programs. We check what is open for your address before we price the job. See the NYC rebate guide.
Common questions
Is cellulose safe? It is recycled paper treated with borate to resist fire and pests.
Will it settle? Not when walls are dense-packed under pressure.
