The Home Insulators

Insulation Contractors in Orange County, NY

29,991 of Orange County’s 148,460 housing units were standing before 1940. That is 20.2% of the stock, and every generation since has added a layer of its own: 14.3% from the 1940s and 50s, 22.3% from the 1960s and 70s, 22.9% from the 1980s and 90s and 20.3% since 2000. The median unit dates from 1975. An insulation contractor here can open a balloon-framed railroad house in Port Jervis in the morning and a 1990s colonial in Chester in the afternoon.

62.4% of units are single-family detached houses, 6.8% townhouses or duplex halves and 1.8% mobile homes, and 68.4% of occupied homes are owner-occupied. Gas heats 47.0% of homes and oil 27.9%, but that average joins two different places: oil heats 68.3% of Crawford and 67.4% of Mount Hope, and 1.8% of Middletown. Where heat comes by truck, sealing pays back as fewer deliveries; where it comes by pipe, as a smaller gas bill and warmer rooms.

Orange is the only New York county on both the Hudson and the Delaware. The east is the river side, from the Hudson Highlands at West Point up through Cornwall and New Windsor to Newburgh. The middle is the Wallkill River valley, with Goshen, the county seat, and Middletown, and Route 17 running through Monroe, Woodbury, Chester and Wallkill; in the south the valley widens into the Black Dirt Region around Warwick. The Shawangunk Ridge sets off the western corner, with Port Jervis beyond it on the Delaware. The twenty-one town and city pages carry the detail.

The houses across Orange County

The oldest layer is thickest where the county’s trade was. 54.2% of Port Jervis, the canal and Erie Railroad town, predates 1940, as do 49.4% of the City of Newburgh and 32.3% of Middletown. We open those frame houses expecting balloon framing, stud bays running from cellar to attic, plaster on lath and wiring to check before any wall is filled. Many hold several households: two- to four-family buildings are 42.2% of the City of Newburgh’s units and 21.0% of Middletown’s, and a shared stair hall makes each building one job, decided by its owner.

Away from the cities the old house is a village house or a farmhouse: 22.3% of Warwick predates 1940, 21.9% of Montgomery and 20.0% of Goshen. Most grew in pieces, a main block with a kitchen wing over a crawl space, whose seams leak more than any wall. Stone houses survive from the 1700s, the Bull Stone House of 1722 still lived in by the family that built it; stone has no cavity, so the work goes to the attic, the sill and any frame wing. Lake houses at Greenwood Lake and the summer colony at Lake Osiris add shallow rafters and floors built for July.

The 1940s and 50s, 14.3% of the county, left capes and small ranches, heaviest in Cornwall at 20.7% and the Town of Newburgh at 17.7%: knee walls with joist bays open to the eaves, and long attics of settled loose-fill. The 1960s and 70s, 22.3%, are the largest cohort in New Windsor at 31.1%, Wallkill at 30.8% and Blooming Grove at 30.6%, where raised ranches and split-levels leak at a bare rim joist above grade, a cantilevered overhang and a garage ceiling under a bedroom.

The 1980s and 90s, 22.9% of the county, built colonials and contemporaries: 33.4% of Hamptonburgh, 32.6% of Woodbury and 32.5% of Chester. Their walls hold batts; their losses are the attic plane, two-story foyers, cathedral ceilings packed tight to the roof deck, bonus rooms over garages and ducts in vented attics. Houses built since 2000, 26.4% of Wallkill, have full walls; the work is attics, ducts and hillside walkouts. Attached houses reach 19.7% of Highlands and 13.8% of Chester, where the party wall and an attic the association may own set the limits of one owner’s job.

Mobile homes, 14.6% of Deerpark and 8.2% of Highlands, lose heat through torn bellies and loose ducts; that conversation starts on the phone. Buildings of fifty or more units are 11.2% of the City of Newburgh and 10.6% of Port Jervis, and 30.3% of Palm Tree’s units sit in buildings of ten to nineteen. There the owner or the association decides for the whole building.

We seal before we insulate

Insulation works on heat conducted through a ceiling or a wall, not on air moving around it. Open stud bays, chimney chases, recessed lights and knee walls give that air easy routes, and warm air leaving through them takes its heat along, however deep the insulation beside them.

In an oil-heated farmhouse in Crawford or Wawayanda the order runs: check how the boiler and any wood stove get their combustion air; seal the fieldstone sill and the rim; close the seams where the wing meets the house; seal the attic floor, hatch and fans, and the chimney chase with sheet metal and fire-rated sealant; add depth last. A balloon-framed Port Jervis house gets its stud bays blocked at cellar and attic before any wall is dense-packed.

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

What insulation costs in Orange County

Most of our projects run between $3,500 and $12,500. The figure follows the house: wall bays and wiring in a pre-war two-family, the stone sill and wing crawl space of a farmhouse, the rim, overhang and garage ceiling of a raised ranch, cathedral slopes and attic ducts in a 1990s colonial. Spray foam insulation in Orange County belongs at rim joists on fieldstone and block, in rafter bays too shallow for anything else, such as the roof of a lake house turned year-round, and in basements that have taken water, as some in Port Jervis have; the open attic floor and the old wall usually get loose-fill or dense-pack. Our guide to spray foam insulation cost explains the price.

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 Orange County

In New York the electric company sets which insulation programs a house can use, and Orange County has three. Orange & Rockland serves most of the county: Middletown, Port Jervis and the towns of Blooming Grove, Chester, Deerpark, Goshen, Greenville, Highlands, Minisink, Monroe, Mount Hope, Palm Tree, Tuxedo, Wallkill, Warwick, Wawayanda and Woodbury. Central Hudson serves the Newburgh area: the City and Town of Newburgh, New Windsor, Cornwall, Hamptonburgh, the villages of Montgomery and Maybrook, and most of the Town of Montgomery outside them. NYSEG serves the Village of Walden and parts of the Town of Montgomery, and most of Crawford is Orange & Rockland territory with parts on NYSEG. In a split town, your bill settles it.

Gas does not always come from the electric company. Most of Middletown, Port Jervis and Palm Tree is on Orange & Rockland gas lines. Goshen buys Orange & Rockland electricity and NYSEG gas, and Central Hudson is listed as the gas company in Highland Falls and the Village of Woodbury. Most of the City of Newburgh is on Central Hudson gas, which also runs on many streets in the Town of Newburgh, New Windsor and Cornwall. Crawford, Mount Hope, and the towns of Chester, Monroe and Warwick outside their villages have little or no utility gas service.

All three electric companies collect the System Benefits Charge, so every one- to four-family home in the county sits in the same NYSERDA program lane. For market-rate owners, NYSERDA’s Comfort Home program pays $2,500 toward sealing and insulating the attic and rim joist, $3,000 if walls and floors are added, and $2,000 more toward ENERGY STAR windows, through a NYSERDA-approved Comfort Home contractor. Every condition of a package has to be met, and a house still wired with knob-and-tube may not qualify. Comfort Home is open in 2026 and closes when the new utility programs start around January 2027, so a homeowner who wants Comfort Home money should not wait.

Income-eligible households, owners and renters alike, go to NYSERDA’s EmPower+ for a primary residence. Orange County’s limits for four people are $80,160 or less for air sealing and insulation at no cost up to $14,000, and under $106,880 for half the cost up to $7,000, through an EmPower+ contractor. Federal HEAR money inside EmPower+ adds up to $1,600 for air sealing, insulation and ventilation.

Orange & Rockland points customers to NYSERDA’s Comfort Home and EmPower+ programs and its Sealed home-upgrade program. NYSEG has offered its own insulation and air-sealing incentive for one- to four-unit homes; ask us or NYSEG what is open when you call.

Neither Comfort Home nor EmPower+ pays for work outside its own participating contractors, so check the MyEnergy portal before you sign. The federal insulation tax credit (Section 25C) ended for work placed in service after 31 December 2025, so there is no federal insulation credit on a 2026 job, and New York has no state tax credit for insulation. Each program is laid out in our insulation rebate guide for New York and New Jersey.

Code and climate in Orange County

56.8% of Orange County’s housing was built before 1980, from 82.4% of the City of Newburgh down to 7.1% of Palm Tree. New York’s first statewide energy code took effect on 1 January 1979, and houses built before that date answered to no state energy rule. Orange County is Climate Zone 5.

Since 31 December 2025, new houses have been built to the 2025 Energy Conservation Construction Code of New York State. Its Zone 5 table asks for R-49 in the ceiling, or R-38 laid over all of it at full, uncompressed height over the wall top plate at the eaves; R-30 floors; R-15 continuous, R-19, or R-13 plus R-5 continuous on basement and crawl space walls; U-0.27 windows; and a blower door result of 3.0 air changes per hour or less at 50 pascals.

Insulating an older house does not pull the rest of it up to that table. Unaltered parts need not comply, New York’s code does not require a blower door test when you insulate an existing home, and a wall or roof cavity opened by the work gets filled to full depth. ENERGY STAR’s attic advice for this zone is R-60 over a bare attic floor and R-49 where 3 to 4 inches already sit.

Common questions about insulation in Orange County

Do you install insulation in Orange County, NY?

Yes, in all three cities and the eighteen towns listed above, from Newburgh, New Windsor, Cornwall and Highland Falls on the river, through Goshen, Middletown, Monroe and Chester, to Warwick, Crawford, Deerpark and Port Jervis. We install spray foam insulation, dense-pack and loose-fill, with the air sealing that comes first, in pre-war city houses and two-families, farmhouses, capes, raised ranches, newer colonials and townhouses. For a mobile home, call first; for a large apartment building, the owner or association decides.

How much does insulation cost in Orange County?

Most projects run $3,500 to $12,500. A pre-war two-family in Newburgh, Middletown or Port Jervis is priced as one building, a farmhouse wing by wing, a raised ranch on its rim, overhang and garage ceiling, and a 1980s or 90s colonial mostly on air sealing, cathedral slopes and attic ducts. Closed-cell spray foam costs more per inch, so it goes only where its R-value or its air seal is needed. The walk-through and written price are free.

Are there insulation rebates in Orange County?

Yes, whichever of the county’s three electric companies bills you. A market-rate owner of a one- to four-family home can apply to NYSERDA’s Comfort Home: $2,500 toward sealing and insulating the attic and rim joist, or $3,000 when walls and floors are included, paid through a NYSERDA-approved Comfort Home contractor. Comfort Home closes when the new utility programs start around January 2027. Households under the EmPower+ income limits, renters included, apply there instead. No federal 25C credit applies to 2026 work, and New York offers no state tax credit for insulation.

Which utility do I have in Orange County?

Check the electric bill. Orange & Rockland serves most of the county, including Middletown, Port Jervis, Warwick, Wallkill, Monroe, Woodbury, Chester, Goshen and Highlands. Central Hudson serves the City and Town of Newburgh, New Windsor, Cornwall, Hamptonburgh and most of Montgomery. NYSEG serves Walden, parts of the Town of Montgomery and part of Crawford, which is otherwise Orange & Rockland. Gas can come from another company: Goshen’s is NYSEG, and Highland Falls and the Village of Woodbury list Central Hudson.

We walk the house from the cellar up: the sill, the rim and the foundation first, then the knee walls, the wing seams and any room over the garage, then the attic, where we measure what is there and find the holes beneath it. In oil and propane homes the boiler, the chimney and any wood stove get checked before we tighten anything. You leave with a written scope and a price, and it costs nothing.

Call 914-825-6824 or reach us through the contact form. Hours are 8am–8pm, seven days. We work out of New Rochelle, NY, and every job is done by our own 100-plus in-house crew, never subcontracted.
