Blown-in insulation for finished Manhattan spaces
Most Manhattan apartments and townhouses are finished, and nobody wants to open plaster walls to add insulation. Blown-in solves that: we drill a small hole in each cavity, fill it with dense-pack cellulose or fiberglass, and patch the hole.
Where it works in Manhattan
- Roof cavities over top-floor units: the space between the ceiling and a flat roof is often empty.
- Framed exterior walls: common on rear extensions and on townhouse top floors.
- Floors over unheated spaces: such as a passage or an open storefront below.
Solid masonry walls usually have no cavity to fill. We tell you when that is the case and where your money does more.
How a job goes
- We check each cavity for blocking, wiring and old insulation.
- One small hole per bay, from inside or from the roof.
- Insulation goes in under pressure, so it doesn’t settle.
- Holes are plugged and patched, ready for paint.
Working in your building
We coordinate with your managing agent, send the insurance certificates the building asks for, and keep to its work hours. Blown-in is quieter and cleaner than demolition, which buildings like.
Common questions
How long does it take? Most apartments and townhouse floors take one day.
Is it messy? Dust stays around the holes, and we clean up as we go.
