The Home Insulators

Insulation Contractors in Hudson County, NJ

Hudson County has 317,032 housing units on 46 square miles of land, the smallest and most crowded county in New Jersey, and 31.2% of its occupied units are owner-occupied. That last number is the one that decides what an insulation contractor can plainly offer here. Only 9.4% of the stock is a detached house and 5.8% is attached. 19.4% sits in two-unit buildings and 12.7% in three- and four-unit buildings, while 34.0% is in buildings of twenty units or more, 23.9% of it in buildings of fifty or more.

So the work is the 32.1% in the middle: the frame and masonry two-, three- and four-family buildings and rowhouses where the owner lives on one floor and controls the roof, the cellar and everything between. A tower is a curtain wall or a masonry shell with no cavity, no attic above the top ceiling and an envelope that belongs to a board, a management company or a landlord. We do not pretend otherwise, and we say it on the phone rather than after a drive out.

The stock is old where it is not brand new. 29.8% predates 1940, the largest cohort, then 15.5% from the 1940s and 50s, 18.3% from the 1960s and 70s and 13.6% from the 1980s and 90s, with 22.7% built since 2000 on the redeveloped waterfront and in the Meadowlands. 63.6% of it went up before New Jersey’s first statewide energy subcode of 1 January 1978. Gas heats 65.0% of occupied units, electricity 26.7% — almost all of that in the newer large buildings — and oil only 2.8%. The six town pages carry the detail.

The Hudson County towns we work in

Each page gives that town’s numbers, the assemblies that fail there, and where the line runs between a job and a board decision.

  • Jersey City — 38,163 units built before 1940 and 37,938 in fifty-plus buildings; we work the two- to four-families.
  • Bayonne — 33.7% of the city is two-unit buildings, and the cockloft over the top floor is the job.
  • North Bergen — One of the hilliest towns in the country: the cold room is the lower level cut into the slope.
  • Hoboken — Only 417 detached houses in the mile square; our work is the rowhouse one owner controls.
  • Kearny — 81.0% built before 1980 and 31.3% detached: mill-era attics on the Uplands and post-war capes.
  • Secaucus — The county’s suburban exception at 49.3% owner-occupied: North End attics and Meadowlands crawl spaces.

The houses across Hudson County

The building that defines this county is the small multi-family on a narrow lot, and the assembly that defines it is the cockloft. Bayonne is 46.0% two- to four-family, Kearny 42.4%, North Bergen 33.1%, Jersey City 31.7%. Above the top-floor ceiling in most of them there is no walk-up attic, only a shallow cavity between the ceiling joists and a flat or low-slope roof deck. That cavity is where the heat goes, and it is the assembly most quotes skip because it is awkward to reach. Where it has depth, we air seal the ceiling plane and fill it. Where the deck sits nearly on the joists there is no room to work, and the insulation belongs above the deck at the next roof replacement — a cheap addition to a re-roof and a permanent fix, and we will tell you that instead of selling two inches of nothing.

Under the cockloft, the vertical paths matter more than the walls. In the pre-1940 frame buildings that make up 35.9% of Bayonne, 36.9% of Kearny, 29.1% of North Bergen and 28.8% of Jersey City, we assume balloon framing until a wall proves otherwise: stud bays running from the cellar sill to the roof cavity, feeding the cockloft all winter. They get blocked at the top and the bottom before anything is blown anywhere. The stair chase runs the full height and moves air between floors, and in a four- or five-story rowhouse it behaves like a chimney with a bulkhead door at the top. Knob-and-tube wiring turns up often in this stock and comes out before insulation goes into a wall.

Masonry changes the scope rather than ending it. The brownstone and brick rowhouses of Hoboken, where 33.2% of the city predates 1940, and the brick-fronted two-families across Jersey City and North Bergen have solid walls with no cavity, so nobody should be drilling the front of your building. The work moves to the roof plane and cockloft, the parapet, the stair bulkhead and the skylight curb, the party wall where it runs past the deck, and then downstairs: the cellar ceiling, the rim and the joist pockets where the beams sit in the masonry, and the interior face of the foundation wall where there is headroom. On this county’s low ground, from the Bayonne peninsula to the Meadowlands, cellars take water, and closed cell foam does not go on a wall that floods.

Away from the rowhouse belt the county turns ordinary. Kearny is 31.3% detached with 45.4% owner-occupancy, the most conventional market here: mill-era houses with floored storage attics that hide an unfilled ceiling, and post-war capes whose knee walls have no air barrier behind them. Secaucus, at 49.3% owner-occupied and 26.1% detached, adds pitched-roof houses on the North End and crawl spaces over damp meadow ground. North Bergen sits on the Palisades, and on a slope the cold room is the lower level: a foundation wall buried at the back and standing in open air at the front, with a band of framing where the two meet and a garage cut in under the living space.

The newest 22.7% is a separate market with a separate answer. Jersey City has built 27.7% of itself since 2000, Hoboken 31.7% and Secaucus 31.0%, and those walls are already full. In the towers there is no job for us. In the low-rise new construction, the infill townhouses and the gut renovations there is: the party wall running uncapped past the roof deck, cathedral and tray ceilings framed with no baffles, ducts and an air handler sitting outside the insulated shell, and bath fans that stop in the roof cavity instead of outdoors.

We seal before we insulate

Insulation slows heat moving through a surface. It does nothing about air moving through a gap. Fill a three-family’s cockloft while the side-wall stud bays and the stair chase stay open, and you have insulated the lid of a chimney that is still drawing.

In the building type that carries this county, the order is: block the stud bays at the sill and at the top plate, close the stair chase at the bulkhead, seal the pipe and flue chases and the top-floor ceiling plane, cap the party wall at the roof deck, then insulate the cockloft to whatever depth it holds. The cellar follows — rim, joist pockets, the openings around the gas line and the old coal chute. In a house with a real attic, it is the top plates, the chases and the hatch first, then depth, then the floor over the garage.

If a quote specifies a depth of insulation and never mentions air sealing, it is half a job.

What insulation costs in Hudson County

Most of our projects run between $3,500 and $12,500. In this county the number moves with how many floors the air has to travel through, how much of the ceiling plane can be reached from inside, the feet of party wall and stud bay to block, and whether the cellar is dry enough to insulate at all. A two- or three-family is scoped and priced as one building, because the stair chase and the floor cavity between units carry air through every apartment and sealing one ceiling does nothing for the others.

Open cell foam runs R-3.9 to R-4.2 per inch. Closed cell runs R-6.9 to R-7.1 per inch and also acts as a vapor retarder, which is why it costs more and why it is right in some assemblies and unnecessary in others. All products are manufactured in the United States and meet applicable building code and safety standards. After air sealing and insulating, homeowners typically save 20% or more on heating and cooling.

Insulation rebates in Hudson County

PSE&G supplies both the electricity and the gas in all six towns — Jersey City, Bayonne, Kearny, North Bergen, Secaucus and Hoboken — and in the rest of the county besides. One company bills both fuels, so there is no question here about which utility leads the rebate conversation, and with 65.0% of occupied units on gas it is usually the gas bill this work brings down.

PSE&G Whole Home Energy Solutions offers up to $7,500 in rebates toward air sealing, insulation and related work, plus 0% on-bill repayment of up to $25,000, over seven years for projects of $10,000 or less and ten years above that or for income-qualified customers. It starts with a home energy assessment by a BPI-certified contractor participating in PSE&G’s program, and the contractor sets that fee; PSE&G does not publish per-measure amounts. Every project has to include air sealing plus the envelope work the assessment calls for.

The eligibility line matters more in Hudson County than anywhere else in the state. The program is written for owner-occupied buildings of one to four units. A three-family with the owner on the parlor floor qualifies; a six-unit building does not, and neither does a rented apartment in a tower. PSE&G’s Whole Home Energy Assessment is free on the same footing — a walk-through with small items installed on the spot, for any PSE&G residential customer in a building of fewer than five units.

For income-qualified households, PSE&G Home Weatherization installs insulation, air sealing and duct sealing at no cost between 250% and 400% of the federal poverty level, or in a low- or moderate-income census tract, or for NJ SHARES customers. New Jersey Comfort Partners does the same at or below 250% of the federal poverty guidelines, $82,500 a year for a family of four, and it reaches buildings of 1 to 14 individually metered units — a wider door than the four-unit ceiling on the rebate program, which is worth knowing in a county full of five- and six-unit buildings.

The New Jersey IRA Home Energy Rebates have not launched. The state’s own page says the programs are in development and not open for applications, so they are not available. The federal Section 25C tax credit ended for anything placed in service after 31 December 2025, and there is no federal insulation credit on a 2026 job whatever a flyer in the vestibule says. The full picture is in our New York and New Jersey rebate guide.

Code and climate in Hudson County

63.6% of Hudson County was built before New Jersey’s first statewide energy subcode of 1 January 1978, and the 29.8% that predates 1940 went up when nothing required insulation in a three-family at all — and in most of them none was installed. Hudson is climate zone 4A, the milder of the state’s two zones; Bergen County, its only land neighbor, is 5A.

New Jersey adopted the 2024 IECC on 17 August 2026. For new construction it sets R-49 ceilings — the 2021 edition it replaced called for R-60 — walls at R-30 in the cavity or R-20 plus R-5 continuous, windows at U-0.30 in a 4A county, and air leakage of 3.0 air changes per hour at 50 pascals. A complete permit application filed under the old code is still accepted for six months, until about 16 February 2027.

A building already standing falls under New Jersey’s Rehabilitation Subcode. Insulating a cockloft or an attic does not require bringing the rest of the building up to current code and does not require a blower-door test. Blown-in or batt insulation installed against the interior finish is ordinary maintenance with no permit; spray foam and other foam plastic insulation need a permit, which we pull as part of the job. R-49 is the number the state considers right for this climate, and it is what we design to.

Common questions about insulation in Hudson County

Do you install insulation in Hudson County, NJ?

Yes, in Jersey City, Bayonne, Kearny, North Bergen, Secaucus and Hoboken, in the buildings one owner controls: two-, three- and four-family houses, rowhouses and brownstones, the detached and semi-detached streets of Kearny and Secaucus, the hillside houses of North Bergen, and low-rise new construction. High-rise buildings are not a retrofit we do. If you own one apartment in a larger building, the roof and the walls are common elements and the decision belongs to your board.

How much does insulation cost in Hudson County?

Most projects run $3,500 to $12,500. What moves the number is the number of floors the air travels through, how much of the top-floor ceiling plane can be reached from inside, the feet of stud bay and party wall to block, and whether the cellar is dry enough to insulate. A two- or three-family is priced as one building rather than one apartment. If the cockloft is too shallow to work in, we will say so and price the roof-replacement route instead.

Are there insulation rebates in Hudson County?

Yes, through PSE&G, which bills both fuels countywide. PSE&G Whole Home Energy Solutions offers up to $7,500 in rebates for air sealing and insulation plus 0% on-bill repayment of up to $25,000, through a BPI-certified contractor participating in the program, and it is written for owner-occupied buildings of one to four units. PSE&G’s separate Whole Home Energy Assessment is free. Comfort Partners does the work at no cost at or below 250% of the federal poverty guidelines, in buildings of up to 14 metered units.

Which utility do I have in Hudson County?

PSE&G, for electricity and gas, in every municipality in the county. There is no split to check here the way there is in Bergen or Mercer, and no second company to confirm with. What does vary is who pays the heating bill and who owns the envelope: in a two- or three-family the owner usually holds both, while in a large building the heat may be electric and through-wall and the roof a common element. That, rather than the utility, is what decides whether a job can go ahead.

Free energy audit in Hudson County

We open the top-floor ceiling plane and measure what is above it, check whether the cockloft has room to work in, look at the stair bulkhead, the parapet and the skylight curb, open a stud bay to see how the walls are framed and whether old wiring is still live, and finish in the cellar at the rim, the joist pockets and the water line on the wall. In a house with a real attic we walk it and check the eaves for wind-washing. Then you get a written scope and a price, no charge and no obligation.

Call 914-825-6824 or use the form on this site. Open 8am–8pm, seven days. We work out of New Rochelle, NY with a 100-plus in-house crew, we never subcontract, and we hold manufacturer installer certifications from the spray foam manufacturers we use.
