Attic insulation on Staten Island
Many Staten Island homes have more than one attic space: a main attic, side attics behind knee walls, and a bonus room over the garage. Each needs its own fix, not one material for the whole house.
What we do
- Main attic you don’t use: air seal the floor, then add blown-in insulation.
- Attic you use, or a cathedral ceiling: spray foam on the underside of the roof.
- Knee walls and side attics: insulate and seal the walls and floors behind them.
- Rooms over the garage: insulate the floor over the garage and the walls around the room.
Seal first
Recessed lights, top plates, plumbing runs and the attic hatch let warm air escape past the insulation. We seal those first.
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
How long does it take? Most attics take one day.
