Blown-in insulation in Brooklyn

Blown-in insulation for finished Brooklyn homes

If your rooms are finished and you don’t want to open walls or ceilings, blown-in is usually the answer. We drill small holes, fill the empty cavity with dense-pack cellulose or fiberglass, and patch the holes.

Brooklyn has a lot of homes built before insulation codes, and many still have nothing in the walls or the roof cavity.

Where it works in Brooklyn

• Frame houses in Midwood, Flatbush, Marine Park and Sheepshead Bay: empty wood-stud walls are ideal for drill-and-fill.
• Brownstone and row-house flat roofs: the space between the top-floor ceiling and the roof deck can be filled from the roof side or from small openings below.
• Attic floors in houses with a pitched roof: loose fill over the ceiling joists.

How a job goes

1. We check each wall and roof bay for blocking, wiring and old insulation.
2. We drill a small hole per bay, from outside or inside.
3. Dense-pack cellulose goes in under pressure so it doesn’t settle.
4. Holes are plugged and patched, ready for paint.

Rebates

Most of Brooklyn has National Grid gas. National Grid’s Total Home Comfort program is paused for new applications, so most one- to four-family homes now go through NYSERDA programs, and buildings with 5 or more units through National Grid’s multifamily program. 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 it is dense-packed. That is why we fill closed cavities under pressure.
