Long Island Blow-In Insulation
Loose-fill blow-in for open attics and top-ups over settled insulation, with even coverage across the attic floor.
What is Blow-In Insulation?
Attic blow-in cellulose and fiberglass loose-fill insulation to restore lost R-value in Long Island homes. We provide uniform coverage around complex framing and wiring to eliminate cold spots and maximize energy savings.
The blow-in scope
From thin attic to full coverage
Measure first, protect the vents, then blow to the depth the attic needs.
Step 01
Measure and air-seal
We check existing depth, find cold spots, and seal attic penetrations so the new fill works as hard as it should.
Step 02
Set soffit baffles
Baffles keep insulation out of the soffit vents so the attic still breathes while you get full coverage at the eaves.
Step 03
Blow to target depth
Cellulose or fiberglass is blown across the attic floor to the depth that hits Long Island attic R-values, even around wiring and framing.
Step 04
Check coverage and clean up
We verify depth markers across the attic, confirm eaves stay clear of the baffles, and leave the access area clean for the next trade or homeowner.
Where it goes
Attic floors, top-ups, and vented eaves
Blow-in insulation fits open attic floors. We use it for a new fill, a top-up over settled insulation, and full coverage at the eaves without blocking soffit vents.
New open attic fill
A full blanket of cellulose or fiberglass blown across the attic floor to the depth that hits R-30 and beyond, filling every bay between the joists.
Top-up over settled insulation
Older attics settle and lose R-value. We measure what’s left and blow a new layer on top so coverage is even again without stripping the old fill.
Vented eaves with baffles
Soffit baffles keep insulation out of the vents so the attic still breathes while you get full coverage right out to the eaves.

FAQ
Common questions about blow-in insulation.
Attic blow-in (loose-fill) is cellulose or fiberglass fed through a hose and blown onto the open attic floor. It settles into an even blanket at the depth you need, filling around wiring, plumbing, and odd framing that batts often miss.
