The Home Insulators

Insulation Contractors in Palisades Park, NJ

A third of Palisades Park has been rebuilt since 2000. 31.8% of the borough’s 7,612 housing units are that new, the highest share of any Bergen County town we cover, and the form they took is the side-by-side duplex on a 5,000 sq ft lot. The Census counts each half as a one-unit attached house, which is why the borough reads 21.5% attached: those are duplex halves, not rowhouses.

Those houses do not need what most insulation pages sell. Their walls were built to the energy codes of 2000 to 2015 and are full. What they need is the party wall sealed, the floor over the garage closed and the air handler in the attic dealt with. This page is for the owner of one of those halves, and for the owner of the older two-family the duplexes are replacing.

The houses we insulate in Palisades Park

The median Palisades Park home was built in 1976, and the number hides more than it shows. 11.5% of the borough predates 1940 and 23.0% is 1940s–50s, but the 31.8% built since 2000 pulls the median forward. Only 16.8% of units are detached houses. 21.5% are one-unit attached, 32.8% are in two- to four-unit buildings, with 1,896 units in two-family buildings alone, 11.3% are in buildings of five to 19 units and 17.2% in buildings of 20 or more. Owner-occupancy is 37.2%, the lowest of any Bergen town we cover, so the person who signs is often a landlord.

The duplex is the borough’s own form. Palisades Park has allowed one- and two-unit houses on 5,000 sq ft lots since its 1939 zoning; two-unit buildings were already a quarter of its roughly 4,000 units by 1959; and duplex redevelopment accelerated greatly through the 1990s and 2000s. Between 2000 and 2019 the one- to four-unit stock grew by 24%, and by 2018 an estimated 55% of it was two-unit and another 14% three- to four-unit. The population is up 154% since 1940. Broad Avenue is the borough’s spine, and on the residential blocks the pattern repeats: a cape came down, and a pair of attached units with garages underneath went up on the lot.

Those duplexes were built to the 2000–2015 energy code, so their walls are insulated and blown-in is not the job. The party wall between the two halves is: it is often unsealed at the top and open to both attics, so the two houses share one air path. The garage-under first floor is: the joist bays over the garage run open into the living space above. Then the cantilevered bays; a flat or low-slope roof that is a joist cavity with no soffit-to-ridge path, so it cannot be vented — dense-pack it, or rigid board above the deck at the next re-roofing, never vented batts; and the air handler sitting in the attic outside the insulation, with the bath fans exhausting into the same attic.

That is why we scope a duplex as an envelope job rather than a wall job, and why a quote for blown-in walls on a post-2000 duplex should make you ask questions. The savings are in sealing the party wall at the attic, closing the garage ceiling and the cantilevers, sealing and insulating the attic ducts and putting the bath fans outside. It is also why a duplex half is easier to do right with the neighbor’s half in the conversation: the party wall has two sides.

The older two-families and the capes that are left

The other half of Palisades Park is what the duplexes are replacing. 11.5% of the borough predates 1940 and 23.0% is 1940s–50s: up-and-down two-families with a shared stair chase, a low-slope roof over the top unit, one heating plant in the cellar and balloon-framed side walls with stud bays open from sill to attic; and, on the 5,000 sq ft lots that have not turned over, capes and ranches with unsealed knee walls, joist bays open to the eave and settled loose-fill in a shallow attic. Many of the capes carry asbestos-cement shingle siding, which we fill from inside or by lifting shingles, never by drilling.

In the pre-1940 houses we check for pre-1950 wiring and for vermiculite in the attic flat before anything goes into a wall. The borough sits on top of the Palisades and falls westward to Overpeck Creek, and on the low streets toward the creek we find crawls and lower levels that have been wet, batts down out of the joist bays and walls stripped after a flood and never re-insulated. There we seal and insulate the first-floor deck rather than the wall that floods.

We seal before we insulate

Insulation slows heat moving through a surface. It does nothing about air moving through a gap. In a duplex whose walls are already full, the gaps are the whole job.

The sequence in Palisades Park is: seal the party wall where it meets the attic and close its cavity at the top; seal the garage ceiling and the rim above the garage door; block and seal the cantilevered bays; seal the air handler platform and every duct connection; run the bath fans out through the roof or wall instead of into the attic; then insulate the attic floor or dense-pack the flat roof. In the older two-families the stair chase and the stud bays at the plates come first. In that order the building holds the heat it pays for.

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

What insulation costs in Palisades Park

Most of our projects run between $3,500 and $12,500. In a post-2000 duplex the number is set by the party wall length and attic access, the floor area over the garage, the flat-roof area if it is dense-packed, and how much duct is in the attic. An older two-family is priced as one building, not two apartments, by the count of stud bays to block and dense-pack and the roof cavity over the top unit.

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. ENERGY STAR says sealing air leaks and adding insulation can save up to 10% on annual energy bills.

Insulation rebates in Palisades Park

Palisades Park is PSE&G territory for both electric and gas, and 76.3% of the borough heats with gas. In a town where only 37.2% of units are owner-occupied, two of the programs below matter more than the rebate: they cost the household nothing.

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 7 or 10 years. It starts with PSE&G’s home energy assessment, and the work must be done by a BPI-certified contractor participating in PSE&G’s program. PSE&G does not publish per-item amounts. The Whole Home Energy Assessment itself is free for any PSE&G gas or electric customer, once a year.

PSE&G Home Weatherization provides insulation, air sealing and duct sealing at no cost for households above 250% and below 400% of the federal poverty level. New Jersey Comfort Partners does the same for households at or below 250% of the federal poverty guidelines, for example $82,500 for a family of four; homes heated with oil or propane are referred to the state weatherization office. The New Jersey IRA Home Energy Rebates have not launched — the state’s page says “under development” — so they are not available yet. See the full New Jersey rebate guide.

The federal Section 25C tax credit ended for anything placed in service after 31 December 2025. There is no federal insulation credit on a 2026 job.

Code and climate in Palisades Park

53.5% of Palisades Park predates 1980, and New Jersey’s first statewide energy subcode took effect on 1 January 1977: about half the borough was built with no energy code, and the third built since 2000 under codes that already required insulated walls. Bergen County is climate zone 5A; Essex, Hudson and Union next door are 4A.

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, and a permit application filed under the old code is still accepted for six months, until about mid-February 2027 — with walls at R-20 plus R-5 continuous, windows at U-0.28, and air leakage of 3.0 air changes per hour at 50 pascals. R-49 is the number the state considers right for this climate, and it is what we design to.

A house already standing falls under New Jersey’s Rehabilitation Subcode: insulating the attic does not require bringing the rest of the house to code or a blower-door test. Blown-in or batt insulation against the interior finish is ordinary maintenance with no permit; spray foam and other foam plastic insulation need a permit, which we pull.

Common questions about insulation in Palisades Park

Do you install insulation in Palisades Park, NJ?

Yes. Most of what we do in Palisades Park is the post-2000 side-by-side duplex, where the walls are already insulated and the job is the party wall, the garage-under floor, the cantilevers, the attic ducts and the flat roof. We also do the older up-and-down two-families (32.8% of the borough’s units are in two- to four-unit buildings) and the capes and ranches that have not been replaced yet.

How much does insulation cost in Palisades Park?

Most projects run $3,500 to $12,500. For a duplex half the drivers are the party wall length and attic access, the floor area over the garage, the flat-roof area if it is dense-packed, and the amount of duct in the attic. An older two-family is priced as one building, by the count of stud bays to block and dense-pack and the roof cavity over the top unit.

Are there insulation rebates in Palisades Park?

Yes. Palisades Park is PSE&G territory for gas and electric. PSE&G Whole Home Energy Solutions offers up to $7,500 in rebates plus 0% on-bill repayment of up to $25,000, starting with a free home energy assessment. Households at or below 250% of the federal poverty guidelines can get the work at no cost through New Jersey Comfort Partners, and those above 250% and below 400% through PSE&G Home Weatherization. There is no federal 25C credit on a 2026 job.

We own one half of a side-by-side duplex in Palisades Park. Does the neighbor’s half need to be done too?

No, but the party wall has two sides, and an open party-wall cavity is a shared draft. We can seal the top of the wall from your attic, close your garage ceiling and cantilevers, seal your ducts and vent your bath fans without touching the other half. If the neighbor does theirs at the same time, both attics get closed and the result is better for both of you.

We walk the attic to find the top of the party wall, the air handler and the bath fans, then the garage ceiling and cantilevers and, in an older house, the cellar, the stair chase and the roof over the top unit. If the walls are full and the job is sealing, we say so and price it that way. Then a written scope and a price. No charge, no obligation.
