Insulation in New York, NY
Crawl space encapsulation and vapor barrier work in New York means contending with century-old masonry, steam heat, and buildings that were framed before modern vapor science existed. Most homeowners call us because their floors are cold, their heating bills jump every January, or they smell must rising through the floorboards. We diagnose the whole envelope, then fix it with materials from Rockwool, CertainTeed, and Knauf. Call (855) 657-3403 and a live person answers, 24/7.
Why New York Homes Are Different
New York’s housing stock is unlike almost anywhere else in the country. The dominant buildings are pre-war solid-brick and brownstone construction from roughly 1890 to 1940. Those masonry walls have no stud cavities to fill, which changes how every insulation job is planned. Contractors have to choose between interior rigid foam against the brick, which eats floor space, or exterior insulation that needs DOB permits and Landmarks Preservation Commission approval in historic districts.
The climate is ASHRAE Zone 4A: real heating loads in winter, hot humid summers, and high embodied humidity from the rivers and harbor. But the more distinctive problem here is winter overheating. One-pipe steam systems have no room-level control, so apartments routinely run above 80°F in January, tenants crack windows, and under-insulated walls make the whole building envelope work against itself. Add Local Law 97 carbon fines now hitting large buildings, and insulation in New York isn’t a comfort upgrade anymore. It’s a compliance line item. Co-op and condo boards now ask about air sealing and vapor barriers the way they used to ask about lobby renovation.
Our Main New York Services
Two jobs dominate our calendar in New York: attic insulation for the single-family stock in Staten Island, southeast Queens, and parts of the Bronx, and the full suite of building-envelope work for masonry multifamily buildings across Manhattan, Brooklyn, and the rest of the boroughs.
Attic Insulation in New York
Attics in New York range from true stand-up spaces in single-family homes to shallow roof decks over top-floor apartments. The constant is winter heat loss: warm air rises through leaky framing, snow melts unevenly on roofs, and ice dams form at the parapets. We start every attic job with air sealing, then build the thermal layer to match the building’s construction. For a full breakdown of Attic Insulation in New York, that’s our dedicated page.

Crawl Space Encapsulation & Vapor Barrier in New York
Crawl spaces in New York are mostly found under single-family homes in Staten Island, southeast Queens, and the eastern Bronx, where the ground stays damp through every season. Because New York’s summers push serious humidity, an unsealed crawl space isn’t a minor flaw: it feeds moisture straight into floor framing, ruins stored belongings, and invites mold. This is the one job that fixes the entire indoor air quality profile of a house at once. Our Crawl Space Encapsulation & Vapor Barrier work starts with a moisture and framing inspection, then builds a sealed, conditioned barrier from the ground up.
Crawl Space Vapor Barrier
Signs you need it
Standing water after rain, damp insulation hanging from floor joists, or a persistent must odor in the rooms directly above the crawl space.
What it costs in New York
A vapor barrier installation in New York typically runs between $3 and $6 per square foot depending on access and ground condition.
How we do it
We clear debris, cap or repair any ground moisture, then lay a reinforced poly barrier up the foundation walls and seal every seam and penetration.
Crawl Space Encapsulation
Signs you need it
High indoor humidity in summer, cold floors all winter, and moisture wicking up through foundation walls even in dry weeks.
What it costs in New York
Full crawl space encapsulation in New York generally lands between $7 and $12 per square foot for a conditioned, sealed system.
How we do it
We seal the full perimeter, line walls and floor, install a dehumidifier where needed, and add a sump pump if groundwater is active.
Crawl Space Insulation
Signs you need it
Floors that stay cold no matter the thermostat setting, or visible gaps where rim joists meet the foundation.
What it costs in New York
Crawl space insulation in New York typically costs between $1.50 and $4 per square foot depending on material and depth.
How we do it
We insulate rim joists and foundation walls with rigid foam or closed-cell spray foam, then re-seal any air gaps around plumbing and wiring.
What Crawl Space Encapsulation & Vapor Barrier Costs in New York
| Item | Typical range in New York |
|---|---|
| Vapor barrier (poly, seams sealed) | $3-$6 per sq ft |
| Full encapsulation with dehumidifier | $7-$12 per sq ft |
| Crawl space insulation | $1.50-$4 per sq ft |
| Ground moisture repair / sump pump | $600-$2,200 |
Does a vapor barrier matter if my crawl space looks dry in winter?
Yes. New York winters freeze the ground, but spring thaw and summer humidity push moisture back up fast. A dry January crawl space can be soaked by May. What matters is year-round ground moisture, not what it looks like on the coldest day.
Will encapsulation make the floors warmer in my Staten Island home?
Usually yes within the first full heating season. Sealing the crawl space stops cold, damp air from sitting under the floor framing, and the thermal layer keeps conditioned air where it belongs. Call (855) 657-3403 for an exact quote on your square footage.
Spray Foam Insulation in New York
Spray foam earns its keep in New York by doing two jobs at once: it insulates and air-seals in a single pass, which matters when you’re working against solid masonry or irregular timber framing. For pre-war buildings with steam heat, closed-cell foam against the roof deck or exterior wall stops the stack effect that pulls heated air out the top of the building. Our Spray Foam Insulation crews are certified applicators using Icynene and Demilec products, and we handle the permit and board-approval paperwork that New York co-ops and condos require.
Closed-Cell Spray Foam
Signs you need it
Air leaks you can feel around rim joists and sill plates, or moisture condensing on masonry walls during cold snaps.
What it costs in New York
Closed-cell spray foam in New York typically runs $2.50 to $5 per board foot installed at 1 inch of depth.
How we do it
We prep the cavity, set up ventilation and containment, then spray in lifts to the specified depth for both R-value and vapor control.
Rim Joist Spray Foam
Signs you need it
Cold band joists in winter, rodent entry points at the foundation line, and drafts rising through floor framing.
What it costs in New York
Rim joist spray foam in New York typically costs between $2.50 and $4.50 per board foot installed at 2 inches.
How we do it
We seal the entire rim joist perimeter with closed-cell foam, which insulates and blocks the air path in one application.
What Spray Foam Insulation Costs in New York
| Item | Typical range in New York |
|---|---|
| Closed-cell spray foam | $2.50-$5 per board foot |
| Open-cell spray foam | $1.50-$3.50 per board foot |
| Rim joist spray foam | $2.50-$4.50 per board foot |
| Spray foam roof deck | $3-$6 per board foot |
Is closed-cell foam worth it for a pre-war brownstone?
For exterior-facing masonry, yes. Closed-cell foam adds structural strength, blocks vapor drive from the brick, and insulates at a higher R-value per inch than anything you can put in a stud cavity. It’s the most space-efficient option in New York’s tight floor plans.
Can spray foam be installed in a landmarked building?
Usually yes, but only after Landmarks Preservation Commission sign-off if the work is visible from the exterior. Interior cavity work rarely requires LPC review. We handle the approval process with your board. Call (855) 657-3403 and we’ll map it out.
Blown-In Insulation in New York
Blown-in insulation is the workhorse upgrade for New York’s single-family and low-rise housing stock, especially where existing wall cavities or attic floors already have some insulation but not enough. Dense-pack cellulose in particular performs well in older wood-framed homes in Staten Island and Queens because it fills irregular cavities that fiberglass batts miss. Our Blown-In Insulation work uses GreenFiber and Johns Manville products, and we air-seal before we blow so the new material actually holds the thermal line.
Blown-In Cellulose
Signs you need it
Thin or settled attic insulation, rooms that overheat in summer, and high bills that don’t match the square footage.
What it costs in New York
Blown-in cellulose in New York typically runs between $1.50 and $3 per square foot installed at standard depth.
How we do it
We seal attic bypasses first, blow cellulose to the target depth, and verify final R-value with a depth gauge before we leave.
Dense-Pack Wall Insulation
Signs you need it
Cold exterior walls in an older wood-framed house, drafts at outlets and baseboards, and rooms that never hold temperature.
What it costs in New York
Dense-pack wall insulation in New York typically costs between $2.50 and $5 per square foot of wall area.
How we do it
We drill small access holes, dense-pack cellulose into the cavity at pressure, then patch and leave the walls ready for paint.
What Blown-In Insulation Costs in New York
| Item | Typical range in New York |
|---|---|
| Blown-in cellulose attic | $1.50-$3 per sq ft |
| Blown-in fiberglass attic | $1.75-$3.50 per sq ft |
| Dense-pack wall insulation | $2.50-$5 per sq ft |
| Blown-in top-up | $1-$2 per sq ft |
Can you blow insulation into a brownstone’s exterior walls?
Generally no. Most brownstones have solid masonry walls with no stud cavities, so there’s nothing to blow into. The effective options are interior rigid foam or spray foam against the masonry. We’ll tell you which works for your specific wall assembly before we quote anything.
How long does blown-in insulation last in New York’s climate?
Cellulose and fiberglass both last decades when the attic stays dry, but any roof or parapet leak will settle and degrade them. We check for moisture intrusion before every blow-in job and recommend fixing the leak first if we find one. Call (855) 657-3403 for an attic evaluation.
Radiant Barrier Installation in New York
Radiant barrier makes the most sense in New York on the top floor of any building under a flat or low-slope roof, where summer sun turns the roof deck into a radiator aimed straight down into the living space. In an uninsulated or under-insulated attic, a foil radiant barrier on the roof deck or rafters reflects a major share of that radiant gain before it becomes a cooling load. Our Radiant Barrier Installation work is typically paired with air sealing and attic insulation, since radiant barrier alone won’t fix winter heat loss.
Attic Radiant Barrier
Signs you need it
A top-floor space that stays 10°F hotter than the rest of the building in summer, or an attic floor that radiates heat well after sunset.
What it costs in New York
Attic radiant barrier installation in New York typically runs between $1.50 and $3 per square foot installed.
How we do it
We staple or fasten a reflective foil layer to the underside of the roof deck or attic rafters, leaving the recommended air gap for performance.
Radiant Barrier Roof Deck
Signs you need it
Dark roof membranes on flat roofs, air conditioning that can’t keep up in August, and top-floor ceiling temperatures well above ambient.
What it costs in New York
Radiant barrier roof deck work in New York typically costs between $1.75 and $3.50 per square foot installed.
How we do it
We install the barrier under the roof deck with attention to ventilation, so radiant heat is reflected without trapping moisture.
What Radiant Barrier Installation Costs in New York
| Item | Typical range in New York |
|---|---|
| Attic radiant barrier | $1.50-$3 per sq ft |
| Radiant barrier roof deck | $1.75-$3.50 per sq ft |
| Radiant barrier foil | $1-$2.50 per sq ft |
| Radiant barrier with ventilation | $2-$4 per sq ft |
Does radiant barrier do anything in January in New York?
Very little by itself. Radiant barrier reflects radiant heat, which is a summer problem. It does not add meaningful R-value against conduction. That’s why we always pair it with air sealing and insulation so the attic works year-round, not just in July.
Is radiant barrier worth it on a flat-roof brownstone?
If you have a ventilated attic or crawl space under the roof deck, yes, it can cut top-floor cooling costs meaningfully. If the roof is directly attached to the ceiling, there’s no air gap, and the better investment is insulation at the roof line. Call (855) 657-3403 and we’ll tell you straight what your roof assembly actually needs.
Insulation Removal & Replacement in New York
Old insulation in New York is often a liability: vermiculite from pre-1990 attics, shredded newspaper from the 1940s, or fiberglass matted down by decades of roof leaks and squirrel traffic. Removal isn’t just a cleanup job. It’s how you recover the thermal envelope and start over with a clean, dry, properly air-sealed attic. Our Insulation Removal & Replacement crews run HEPA-filtered vacuums and follow containment protocols that keep old dust out of your living space.
Attic Insulation Removal
Signs you need it
Insulation that’s compressed to a fraction of its original depth, stained by leaks, or filled with rodent droppings and nesting debris.
What it costs in New York
Attic insulation removal in New York typically runs between $1.50 and $3 per square foot for standard removal.
How we do it
We set up negative-pressure containment, vacuum out the old material, and bag it for disposal before re-inspecting the attic floor.
Vermiculite & Old Insulation Removal
Signs you need it
Pebbly gray-gold insulation in an attic of a pre-1990 building, which may contain asbestos and should never be disturbed casually.
What it costs in New York
Vermiculite removal in New York typically costs between $4 and $8 per square foot due to testing and disposal requirements.
How we do it
We test first, then follow asbestos-safe removal protocol with licensed handlers and sealed disposal, then replace with new insulation.
What Insulation Removal & Replacement Costs in New York
| Item | Typical range in New York |
|---|---|
| Attic insulation removal | $1.50-$3 per sq ft |
| Contaminated insulation removal | $2.50-$5 per sq ft |
| Vermiculite removal | $4-$8 per sq ft |
| Insulation replacement | $2.50-$5.50 per sq ft |
Can I just leave old vermiculite and blow new insulation over it?
We don’t recommend it. Old vermiculite can contain asbestos, and layering new material over it leaves the hazard in place and hides future problems. Get it tested, and if it’s positive, remove it properly. We handle the whole sequence from test to replacement.
How do I know if my attic insulation is too old to keep?
If it’s compressed below half its original depth, smells musty, or shows signs of pest activity, it’s no longer doing its job and may be contaminating your air. A quick attic inspection settles it. Call (855) 657-3403 for a straight answer.
Attic Air Sealing in New York
Air sealing is the highest-leverage energy upgrade available in New York, especially in buildings that date from the steam-heat era. Every wiring penetration, plumbing chase, and top plate gap in an attic is a chimney pulling heated air out of the building all winter. Sealing those paths before adding insulation is what turns a good retrofit into a great one. Our Attic Air Sealing work starts with a blower-door-guided walkthrough so we seal the actual leak paths, not just the obvious ones.
Top Plate & Penetration Sealing
Signs you need it
Drafts around ceiling fixtures, dust streaks on insulation, and rooms that won’t hold temperature on windy days.
What it costs in New York
Top plate and penetration sealing in New York typically costs between $1.00 and $2.50 per square foot of attic floor.
How we do it
We foam-seal every top plate, wire penetration, and plumbing chase, then re-check with a smoke pencil or thermal camera.
Can Light & Duct Boot Sealing
Signs you need it
Recessed can lights that glow in the attic, ducts that collect dust at the boots, and visible gaps around ceiling penetrations.
What it costs in New York
Can light and duct boot sealing in New York typically runs between $75 and $250 per penetration sealed.
How we do it
We use rated covers for non-IC cans, seal duct boots to the ceiling plane, and verify each seal holds before moving on.
What Attic Air Sealing Costs in New York
| Item | Typical range in New York |
|---|---|
| Attic floor air sealing | $1.25-$3 per sq ft |
| Top plate & penetration sealing | $1-$2.50 per sq ft |
| Can light & duct boot sealing | $75-$250 per seal |
| Attic hatch sealing | $150-$500 per hatch |
Do I need air sealing before adding insulation in a pre-war co-op?
Yes, especially at the roof level. Without sealing, new insulation just filters the same leaky air. In co-op buildings, we also confirm the work is inside the unit’s scope or get board approval before touching shared structure. We handle that paperwork for you.
How much of New York’s heating bill is lost through the attic?
In typical pre-war construction, 25 to 40 percent of a building’s heat loss moves through the roof and top-floor ceiling. Air sealing attacks that loss directly, which is why it’s the first thing we do before adding insulation. Call (855) 657-3403 to schedule a blower-door test.
Wall Insulation in New York
Wall insulation in New York is dictated by the wall assembly itself, and most of this city’s buildings have no cavity to fill. For pre-war masonry, the realistic choices are interior rigid foam against the brick, closed-cell spray foam at the rim and exterior face, or exterior insulation systems that trigger DOB permits and LPC review in landmarked districts. Our Wall Insulation work is planned wall-by-wall, because a brownstone’s front facade and party walls don’t behave the same way.
Drill & Fill Wall Insulation
Signs you need it
Wood-framed walls in Staten Island or Queens homes that feel cold to the touch in winter and show drafts at outlets.
What it costs in New York
Drill and fill wall insulation in New York typically costs between $2.50 and $5 per square foot of wall area.
How we do it
We drill access holes from inside or outside, fill the cavities with dense-pack cellulose or foam, then patch to a paintable finish.
Interior Rigid Foam Insulation
Signs you need it
Solid masonry walls in a pre-war building that stay cold, condense moisture, or leave rooms impossible to heat evenly.
What it costs in New York
Interior rigid foam insulation in New York typically runs between $4 and $8 per square foot installed.
How we do it
We fur out the wall, install continuous rigid foam with taped seams, and finish with drywall or plaster as specified.
What Wall Insulation Costs in New York
| Item | Typical range in New York |
|---|---|
| Drill & fill wall insulation | $2.50-$5 per sq ft |
| Interior rigid foam insulation | $4-$8 per sq ft |
| Exterior wall insulation | $8-$15 per sq ft |
| Interior wall soundproofing | $3-$6 per sq ft |
Why can’t you just blow insulation into my brownstone walls?
Most brownstones are solid brick, not cavity wall. There’s no open space to fill. Adding insulation means sacrificing floor space to interior foam or getting DOB approval for exterior work. We walk you through both options and their costs before you commit.
Do I need Landmarks approval to insulate exterior walls in New York?
If your building is in a landmarked district and the insulation changes the exterior appearance, yes. Interior work usually doesn’t trigger LPC review. We help boards and owners figure out which path applies. Call (855) 657-3403 with your building address.
Attic Cleaning & Rodent Proofing in New York
Rodents in New York attics aren’t a minor nuisance; they’re a building-wide problem. Rats and squirrels chew wiring, displace insulation, and leave behind droppings that contaminate the air and invite secondary pests. In older brick and brownstone buildings, the entry points are often the building’s original construction gaps: party wall openings, roof vent terminations, and parapet copings. Our Attic Cleaning & Rodent Proofing service removes the contamination, sanitizes the space, and seals the building so the problem doesn’t return.
Attic Cleanout
Signs you need it
Droppings in the attic, shredded insulation, disturbed nesting material, or decades of debris from previous construction work.
What it costs in New York
Attic cleanout in New York typically runs between $800 and $2,500 depending on attic size and amount of debris.
How we do it
We remove all debris and contaminated insulation, vacuum with HEPA filtration, and dispose of everything under proper waste protocols.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds at night, new droppings after cleaning, or grease marks along beams where rodents travel.
What it costs in New York
Rodent proofing and exclusion in New York typically costs between $600 and $2,000 depending on entry points and access.
How we do it
We seal every entry point with steel mesh, flashing, and foam where appropriate, then verify the building is closed before we finish.
What Attic Cleaning & Rodent Proofing Costs in New York
| Item | Typical range in New York |
|---|---|
| Attic cleanout | $800-$2,500 |
| Attic sanitizing & decontamination | $1,000-$3,000 |
| Rodent proofing & exclusion | $600-$2,000 |
| Attic restoration | $1,500-$4,000 |
Can you get rid of rats without tearing out all the insulation?
If the infestation is recent and the insulation is dry and intact, we can often clean and treat it instead of removing it. Heavy contamination usually means removal. We’ll tell you which applies after we inspect the attic. Call (855) 657-3403 and we’ll schedule it.
Do I need a separate exterminator before you start?
Not usually. We handle exclusion and proofing, which means sealing the building so rodents can’t get back in. If there’s an active infestation, we’ll recommend a licensed exterminator as part of the plan and coordinate the timing so the sealing work isn’t compromised.
Home Energy Audit in New York
A home energy audit in New York is the diagnostic starting point that makes every other insulation job smarter, because the building’s age and construction type dictate what will actually move the needle. For pre-war buildings, the audit often reveals that air leakage is the dominant problem, not missing insulation. For Local Law 97 compliance, an audit also documents the baseline before any retrofit. Our Home Energy Audit uses blower-door testing and thermal imaging to map exactly where the building loses energy, then hands you a prioritized fix list.
Blower Door Test
Signs you need it
Drafty rooms, uneven temperatures between floors, and heating bills that seem disconnected from actual usage.
What it costs in New York
A blower door test in New York typically costs between $250 and $500 as part of a full audit.
How we do it
We mount a calibrated fan in an exterior door, depressurize the building, and measure total leakage in CFM at standard pressure.
Thermal Imaging Inspection
Signs you need it
Cold spots on walls and ceilings, moisture that’s not visible to the naked eye, or uncertainty about where insulation is actually missing.
What it costs in New York
A thermal imaging inspection in New York typically costs between $200 and $450.
How we do it
We scan every wall, ceiling, and floor plane with an infrared camera while the building is under temperature differential, then document the anomalies.
What Home Energy Audit Costs in New York
| Item | Typical range in New York |
|---|---|
| Blower door test | $250-$500 |
| Thermal imaging inspection | $200-$450 |
| Insulation inspection | $150-$350 |
| Duct leakage test | $200-$400 |
Do I need an energy audit before insulating a pre-war building?
We strongly recommend it. Because pre-war construction has no stud cavities and often more air leakage than conduction heat loss, an audit tells you whether air sealing, roof insulation, or wall treatment will give the best return. You avoid paying for the wrong fix.
Will an energy audit help with Local Law 97 compliance?
Yes. The audit establishes your building’s baseline energy profile, which is exactly what you need when deciding whether an insulation retrofit will change your compliance position. For many boards, that data is the difference between a guess and a plan. Call (855) 657-3403 to schedule one.

What New York Customers Say
"Injection foam in the walls of our 1950s house - no drywall demolition, just small holes patched and painted the same day. The street noise in the front bedroom is half what it was."
- Yasmin Farah"Upstairs was ten degrees hotter than downstairs every summer. They pulled the attic to bare joists, air-sealed every can light and top plate first, then blew it to R-49. First August in this house where the bedrooms and the living room read the same on the thermostat."
- Marcus Hale"Rodents had been in the attic for years before we bought the place. They vacuumed everything out, sanitized, sealed the entry points with mesh and foam, and only then put new insulation down. Photos of every stage before I paid."
- Darnell Whitfield
