Insulation in Yonkers, NY
Insulation work in Yonkers is shaped by housing stock that most of Westchester doesn’t share: attached brick row houses from the 1890s to 1940s with zero wall cavity insulation, balloon-frame two-families in the eastern hills, and a Hudson River wind corridor that pushes cold air through the western neighborhoods. Crawl space encapsulation and vapor barrier work matters especially in the low-elevation riverfront sections where ground moisture moves up through old stone and block foundations. If your heating bills feel out of line with the size of your home, call (855) 657-3403 and we’ll tell you exactly what’s going on.
Why Yonkers Homes Are Different
Yonkers sits just north of the Bronx city line but falls under New York State codes and NYSERDA incentive programs, not NYC’s separate energy code. That single fact changes the retrofit math. The dense southwest corridor along Nodine Hill, The Hollow, and South Broadway was built with attached brick row houses that have virtually no insulation in exterior walls. The same building a few blocks south in the Bronx doesn’t qualify for NYSERDA-subsidized retrofits. In Yonkers, it does.
The hillier eastern sections tell a different story. Crestwood, Dunwoodie, and McLean Heights are full of balloon-frame single-family and two-family homes. Balloon framing means wall stud bays run uninterrupted from basement to attic with no fire stops, which changes how blown-in dense-pack cellulose has to be staged so material doesn’t drop into floor cavities. The Hudson River Valley also channels cold wind directly down through western Yonkers in winter, adding heating load to riverfront homes that sheltered hillside streets don’t feel. Permits for retrofit wall work go through Yonkers’ own Department of Housing and Buildings, an independent step that out-of-town contractors routinely underestimate.
Our Main Yonkers Services
Most Yonkers homeowners reach out to us for one of two reasons: an attic that bleeds heat in winter or a crawl space that keeps the first floor damp and cold. Here’s how both work.
Attic Insulation in Yonkers
In Yonkers, attic insulation is the highest-return upgrade for pre-WWII homes with original insulation that has settled to R-19 or less. We air seal the attic floor before adding blown-in or batt material, which stops the stack effect that pulls conditioned air out of the living space and draws cold air in through rim joists. Most Yonkers attics we see need both sealing and new insulation, not just a top-up. Attic Insulation in Yonkers covers this work in detail.

Crawl Space Encapsulation & Vapor Barrier in Yonkers
Crawl space encapsulation in Yonkers is a moisture-control job first and an insulation job second. The low-elevation neighborhoods along the Hudson and Saw Mill River corridors sit close to the water table, so vapor drive through old stone and concrete block foundations is constant. In the attached row houses of Nodine Hill and The Hollow, a damp crawl space doesn’t just smell musty – it pushes humidity up through the first floor and shortens the life of joists and sill plates. Our Crawl Space Encapsulation & Vapor Barrier service handles the full system, from vapor barrier to dehumidification.
Crawl Space Vapor Barrier
Signs you need it
Exposed dirt floors, a musty smell on the first floor, or warped hardwood in a Yonkers home are telltale signs that ground moisture is finding its way up through the crawl space.
What it costs in Yonkers
A crawl space vapor barrier in Yonkers typically runs $1,500 to $4,500, depending on square footage and whether the space has ledge or irregular terrain.
How we do it
We lay a reinforced 12-mil or thicker poly barrier across the floor, run it up the foundation walls, and seal all seams and piers with mechanical fasteners and tape designed for below-grade contact.
Crawl Space Encapsulation
Signs you need it
Condensation on ductwork, sweating pipes, visible mold on rim joists, or a crawl space that stays damp even after rain-free stretches means you need full encapsulation, not just a floor barrier.
What it costs in Yonkers
Full crawl space encapsulation in Yonkers typically runs $5,000 to $15,000, with the range driven by access height, drainage needs, and whether the walls are stone, block, or concrete.
How we do it
We seal the entire space: floor barrier, wall liner, pier wrapping, sealed vents, and an appropriately sized dehumidifier. The goal is a clean, dry space that stops moisture at the perimeter instead of managing it after the fact.
Crawl Space Insulation
Signs you need it
Cold floors above a crawl space, frozen pipe scares on the coldest nights, or rim joists that feel cold to the touch in January are the usual signals.
What it costs in Yonkers
Crawl space insulation in Yonkers typically runs $1,200 to $4,000 when paired with a vapor barrier, depending on material choice and whether the space is vented or being sealed.
How we do it
We insulate the rim joist band with closed-cell spray foam or rigid foam board, then address the foundation walls with foam board or spray foam depending on the encapsulation strategy.
What Crawl Space Encapsulation & Vapor Barrier Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Crawl space vapor barrier | $1,500 – $4,500 |
| Crawl space encapsulation | $5,000 – $15,000 |
| Crawl space insulation | $1,200 – $4,000 |
| Sump pump and drainage | $1,800 – $4,200 |
How long does crawl space encapsulation last in Yonkers?
A properly installed encapsulation system lasts 20 years or more in Yonkers. The barrier itself can last longer, but dehumidifiers need replacement every 7 to 12 years. Call (855) 657-3403 and we’ll assess your specific space.
Can you encapsulate a crawl space in a Yonkers row house?
Yes, and we do it regularly in Nodine Hill and The Hollow. Row house crawl spaces are tighter and often have shared party walls, but the encapsulation approach works the same way. We size the dehumidifier for the enclosed volume, not the floor area.
Spray Foam Insulation in Yonkers
Spray foam insulation solves two problems at once in Yonkers homes: it insulates and it air seals. That matters in this city because the pre-WWII housing stock leaks air constantly through rim joists, attic hatches, and top plates. Closed-cell foam also adds structural rigidity, which older Yonkers balloon-frame homes often benefit from. We install both open-cell and closed-cell systems from a range of manufacturers, and our Spray Foam Insulation hub explains the differences in depth.
Open-Cell Spray Foam
Signs you need it
Open-cell foam is the right call for attic rooflines and interior walls in Yonkers where you want high R-value per inch and good sound dampening without the vapor barrier properties of closed-cell.
What it costs in Yonkers
Open-cell spray foam in Yonkers typically runs $0.45 to $0.85 per board foot installed, with most attic jobs falling between $2,500 and $6,000 total.
How we do it
We prep the area, apply the foam to the target surface, let it expand and cure, and then trim any excess. The job is done in a day for most attics.
Closed-Cell Spray Foam
Signs you need it
Closed-cell foam is the choice for crawl space walls, rim joists, and below-grade applications in Yonkers where moisture resistance and high R-value per inch both matter.
What it costs in Yonkers
Closed-cell spray foam in Yonkers typically runs $1.00 to $1.75 per board foot installed, with rim joist packages starting around $1,800 and full crawl space jobs ranging higher.
How we do it
We apply the foam in lifts to the target surface, allowing each pass to cure before adding the next. This gives you a continuous thermal and vapor boundary that stays put.
What Spray Foam Insulation Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Open-cell spray foam | $0.45 – $0.85 per board foot |
| Closed-cell spray foam | $1.00 – $1.75 per board foot |
| Rim joist spray foam package | $1,800 – $4,000 |
| Attic roofline spray foam | $2,500 – $6,000 |
Is spray foam safe in older Yonkers homes?
Yes, when installed by trained technicians with proper ventilation and cure time. Open-cell and closed-cell foams are widely used in pre-war homes across Yonkers. We follow manufacturer cure schedules and run fresh-air ventilation during installation.
Can spray foam reduce drafts in a Yonkers brick row house?
It can, especially at rim joists and top plates, which are the main leakage points in attached row houses. Spray foam air seals as it insulates, so drafts drop immediately after installation. Call (855) 657-3403 for a site-specific assessment.
Blown-In Insulation in Yonkers
Blown-in insulation is the workhorse retrofit for Yonkers because so much of the housing stock has empty wall cavities and settled attic coverage. Loose-fill cellulose or fiberglass reaches places batts can’t, especially in the attached brick row houses where finished interior walls hide the lack of insulation. In balloon-frame homes in Crestwood and Dunwoodie, blown-in cellulose requires careful staging to avoid dropping material through full-height stud bays, which is exactly the kind of detail our crews handle daily. Our Blown-In Insulation service hub covers material options and the installation process.
Blown-In Cellulose
Signs you need it
If your attic has settled fiberglass that measures R-19 or less, or if walls feel cold in winter despite decent attic coverage, blown-in cellulose is the fastest correction.
What it costs in Yonkers
Blown-in cellulose in Yonkers typically runs $1.50 to $3.00 per square foot installed, with the cost influenced by target R-value and whether the attic needs air sealing first.
How we do it
We run a hose into the attic or wall cavity and blow the material to the specified density and R-value, checking depth markers as we go. For walls, we drill small access holes and plug them afterward.
Dense-Pack Wall Insulation
Signs you need it
Cold interior walls, high heating bills in an attached row house, or rooms that never quite warm up even when the radiator is hot are classic dense-pack candidates.
What it costs in Yonkers
Dense-pack wall insulation in Yonkers typically runs $2.50 to $5.00 per square foot of wall area, with brick veneer over wood frame on the lower end and solid masonry on the higher end.
How we do it
We drill holes through the exterior sheathing or interior drywall, blow cellulose at high density so it locks into the cavity, and patch the access points to match the existing finish.
What Blown-In Insulation Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Blown-in cellulose attic | $1.50 – $3.00 per square foot |
| Blown-in fiberglass attic | $1.25 – $2.75 per square foot |
| Dense-pack wall insulation | $2.50 – $5.00 per square foot |
| Blown-in top-up over existing | $1.00 – $2.00 per square foot |
Does blown-in insulation settle in Yonkers homes?
Blown-in fiberglass settles a bit and loses R-value; cellulose settles minimally when installed at proper density. We install both to their specified final settled R-value, so the label reflects what you actually live with.
Can you blow insulation into Yonkers brick row house walls?
Yes. Exterior walls in attached brick row houses along Nepperhan Avenue and South Broadway are frequently uninsulated wood frame behind brick veneer, which accepts dense-pack cellulose through drilled access holes. Call (855) 657-3403 for a wall cavity assessment.
Radiant Barrier Installation in Yonkers
Radiant barrier installation in Yonkers targets summer heat gain, not winter heat loss. The city’s 5,000+ heating degree days get the attention, but late-June through August brings real cooling load to third-floor bedrooms and flat-roofed row houses that soak up sun all afternoon. A radiant barrier stapled to the underside of the roof deck reflects radiant heat before it reaches the attic floor. In the dense western corridor where homes sit shoulder to shoulder and cross-ventilation is limited, this single addition can make upstairs rooms livable without cranking window units. Our Radiant Barrier Installation hub has the full breakdown.
Attic Radiant Barrier
Signs you need it
Upstairs rooms that are 5 to 10 degrees hotter than the rest of the house in summer, or an attic that feels like an oven on sunny days, are clear signals a radiant barrier would help.
What it costs in Yonkers
An attic radiant barrier in Yonkers typically runs $1,200 to $3,500, depending on attic size, roof pitch, and whether the space has existing insulation to work around.
How we do it
We staple a foil-faced reflective barrier to the underside of the roof rafters, leaving a small air gap below the roof deck so the foil can reflect rather than conduct heat.
Radiant Barrier & Ventilation
Signs you need it
If your attic has a radiant barrier but still traps heat because soffit or ridge vents are undersized, you need the barrier paired with better airflow.
What it costs in Yonkers
Radiant barrier paired with ventilation improvements in Yonkers typically runs $1,800 to $4,500, depending on how many vents need to be added or enlarged.
How we do it
We install the barrier and then verify that intake and exhaust vent area meet the 1:150 attic ventilation ratio, adding soffit or box vents where the roofline allows.
What Radiant Barrier Installation Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Attic radiant barrier | $1,200 – $3,500 |
| Radiant barrier with ventilation | $1,800 – $4,500 |
| Rooftop radiant barrier foil | $1,000 – $2,800 |
| Garage ceiling radiant barrier | $800 – $2,000 |
Does a radiant barrier help in Yonkers winters?
No. Radiant barriers reduce summer heat gain, not winter heat loss. Yonkers homes need attic floor insulation and air sealing for winter performance. We’ll tell you plainly which upgrade is worth your money.
Can a radiant barrier damage my Yonkers roof?
No, when installed with proper ventilation and the correct air gap. Foil on the roof deck can trap moisture if ventilation is blocked, so we check and upgrade venting at the same time. Call (855) 657-3403 for a roof deck assessment.
Insulation Removal & Replacement in Yonkers
Insulation removal in Yonkers is usually a necessary first step, not a standalone project. Old attics in this city often contain decades of squirrel and raccoon damage, compressed fiberglass from roof leaks, or vermiculite that may contain asbestos. You can’t simply blow new material over contaminated or water-damaged insulation and expect the problem to go away. We remove the old material, sanitize the space, and install fresh insulation to current R-value standards. Our Insulation Removal & Replacement hub covers the full sequence.
Attic Insulation Removal
Signs you need it
Water stains on ceiling drywall, visible rodent tunnels through the insulation, or old material that has compressed to a thin mat are all reasons to remove and start over.
What it costs in Yonkers
Attic insulation removal in Yonkers typically runs $1.50 to $3.50 per square foot, with the range driven by access, material type, and whether contamination is present.
How we do it
We use a high-powered vacuum system to extract the old material into sealed bags, then clean the attic floor and joist cavities before installing new insulation.
Vermiculite & Old Insulation Removal
Signs you need it
If your Yonkers home has shiny, pebble-like vermiculite insulation from the pre-1990 era, it needs testing before any disturbance. Many vermiculite sources contain asbestos.
What it costs in Yonkers
Vermiculite removal in Yonkers typically runs $4.00 to $8.00 per square foot when handled by a licensed abatement contractor, reflecting the containment and disposal protocols required.
How we do it
We coordinate testing, then remove the material under containment using HEPA filtration and proper disposal documentation. We never disturb vermiculite without a test result.
What Insulation Removal & Replacement Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Attic insulation removal | $1.50 – $3.50 per square foot |
| Vermiculite removal | $4.00 – $8.00 per square foot |
| Contaminated insulation removal | $2.50 – $5.00 per square foot |
| Full removal and replacement | $3.00 – $7.00 per square foot |
Can I just blow new insulation over the old in Yonkers?
Sometimes, if the old material is clean and dry and there’s no pest damage. But in many pre-war Yonkers attics, the old insulation hides roof leaks, rodent debris, or vermiculite. We’ll tell you which applies after looking.
How long does insulation removal take in a Yonkers home?
Most attic removals in Yonkers take one day. Full removal plus replacement usually takes two days. Call (855) 657-3403 and we’ll give you a schedule based on your attic’s condition.
Attic Air Sealing in Yonkers
Attic air sealing in Yonkers addresses the stack effect that plagues pre-war homes: warm air rises through every gap around pipes, light fixtures, and top plates, pulling cold outside air in through the rim joist and basement. The wind that moves down the Hudson River Valley in winter makes this worse in western Yonkers neighborhoods than in the sheltered hills to the east. Sealing the attic floor before adding insulation is the single most effective step we take on most Yonkers jobs. Our Attic Air Sealing hub covers the details.
Attic Floor Air Sealing
Signs you need it
Dust streaks on insulation, uneven room temperatures, or a heating system that runs constantly in January all point to air leaks at the attic floor.
What it costs in Yonkers
Attic floor air sealing in Yonkers typically runs $1,000 to $2,500, depending on attic size and the number of penetrations that need to be sealed.
How we do it
We seal every penetration with expanding foam or caulk: top plates, electrical penetrations, plumbing stacks, and any open chases. Then insulation goes on top of a now-continuous air barrier.
Top Plate & Penetration Sealing
Signs you need it
Infrared scans showing cold stripes at wall-to-ceiling junctions, or visible gaps where framing meets drywall, are top-plate leakage signals.
What it costs in Yonkers
Top plate and penetration sealing in Yonkers typically runs $800 to $2,000 as a standalone job, often bundled with attic floor air sealing.
How we do it
We work from the attic side, sealing the seam where interior walls meet the top plate with foam or caulk, and sealing every wire, pipe, and duct that passes through.
What Attic Air Sealing Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Attic floor air sealing | $1,000 – $2,500 |
| Top plate and penetration sealing | $800 – $2,000 |
| Attic hatch sealing | $300 – $800 |
| Can light and duct boot sealing | $500 – $1,500 |
Does air sealing really lower heating bills in Yonkers?
Yes, often by 10 to 20 percent in pre-war homes where air leakage is the dominant heat loss path. Sealing before insulating is the correct sequence and we won’t skip it to save time.
Can you air seal a Yonkers attic in winter?
Yes. Attic air sealing works year-round, and winter actually makes leaks easier to spot with an infrared camera. Call (855) 657-3403 to schedule an attic assessment whenever the draft bothers you most.
Wall Insulation in Yonkers
Wall insulation is the most frequently needed retrofit in Yonkers because the dense southwest corridor along South Broadway and Nepperhan Avenue was built without any wall cavity insulation. The attached brick row houses there lose heat through exterior walls all winter, and the radiators in those homes were sized to overheat in response. Dense-pack blown-in or injection foam can fill those empty cavities from the outside or inside, and because Yonkers falls under New York State’s NYSERDA programs rather than NYC’s separate framework, many of these retrofits qualify for utility incentives. Our Wall Insulation hub covers material and access options.
Injection Foam Wall Insulation
Signs you need it
Cold walls in a row house, plaster that feels clammy in winter, or rooms along party walls that never hold heat are the usual indicators.
What it costs in Yonkers
Injection foam wall insulation in Yonkers typically runs $2.75 to $5.50 per square foot of wall area, with brick veneer on the lower end and solid masonry on the higher end.
How we do it
We drill small holes through the interior or exterior, inject foam that expands to fill the cavity, and patch the holes to blend with the existing finish.
Drill & Fill Wall Insulation
Signs you need it
Balloon-frame homes in Crestwood, Dunwoodie, and McLean Heights where wall cavities are open from top to bottom need careful staging so fill material doesn’t drop through.
What it costs in Yonkers
Drill and fill wall insulation in Yonkers typically runs $2.00 to $4.50 per square foot, with cost depending on wall height, siding type, and staging complexity in balloon-frame construction.
How we do it
We identify fire-stop locations, drill access holes, blow cellulose at dense-pack pressure, and patch every hole. For balloon-frame walls, we stage the work in lifts so material stays where it should.
What Wall Insulation Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Injection foam wall insulation | $2.75 – $5.50 per square foot |
| Drill and fill wall insulation | $2.00 – $4.50 per square foot |
| Interior wall soundproofing | $1.50 – $3.50 per square foot |
| Exterior rigid foam retrofit | $4.00 – $8.00 per square foot |
Can you insulate walls without tearing out plaster in Yonkers?
Yes. Drill and fill and injection foam both work through small access holes with no full wall demolition. We patch the holes afterward so plaster and drywall finishes remain intact. Call (855) 657-3403 for a wall cavity assessment.
Do Yonkers row house party walls need insulation?
Party walls between attached row houses don’t need thermal insulation because both sides are conditioned space. They may benefit from soundproofing. We’ll tell you honestly which walls are worth the work.
Attic Cleaning & Rodent Proofing in Yonkers
Attic cleaning in Yonkers is driven by the city’s dense, older housing stock. Attached row houses share roof lines and party walls, which means squirrels, raccoons, and mice in one home often find their way into the next. Pre-war construction also means plenty of original gaps: open soffit returns, missing mortar, and roofline transitions that invite entry. We clean out contaminated insulation, sanitize the space, and seal entry points so pests can’t return. Our Attic Cleaning & Rodent Proofing hub covers the full service sequence.
Attic Cleanout
Signs you need it
Scratching sounds at night, visible droppings, or tunneling through insulation are all evidence that Yonkers rodents have taken up residence and left contamination behind.
What it costs in Yonkers
Attic cleanout in Yonkers typically runs $800 to $2,500, depending on attic size, the extent of contamination, and whether insulation needs to be removed.
How we do it
We vacuum out contaminated material, bag it for disposal, and prepare the attic for sanitizing. If the insulation is salvageable, we clean around it; if not, we remove it.
Rodent Proofing & Exclusion
Signs you need it
Recurring pest problems despite trapping, chewed wiring, or daylight visible at roofline gaps are signals that exclusion work is the real fix, not another round of bait.
What it costs in Yonkers
Rodent proofing and exclusion in Yonkers typically runs $1,200 to $4,000, with cost driven by the number of entry points and whether roofline or foundation work is needed.
How we do it
We identify every entry point, seal them with steel mesh, flashing, and foam in the right combination, and verify the attic stays pest-free during the 90-day follow-up window.
What Attic Cleaning & Rodent Proofing Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Attic cleanout | $800 – $2,500 |
| Attic sanitizing and decontamination | $500 – $1,800 |
| Rodent proofing and exclusion | $1,200 – $4,000 |
| Full attic restoration | $3,000 – $8,000 |
How quickly can you clean a Yonkers attic after rodent damage?
Most cleanouts happen within a week of your call. If insulation replacement is needed, we schedule the full sequence in one visit where possible. Call (855) 657-3403 for same-week availability.
Does rodent proofing damage my Yonkers roof?
No. Exclusion work seals existing gaps; it doesn’t create new ones. We work from the attic and roofline carefully, matching materials to your home’s construction so nothing looks patched.
Home Energy Audit in Yonkers
A home energy audit is the diagnostic starting point for any Yonkers retrofit. Because this city’s housing spans attached brick row houses, balloon-frame wood homes, and multifamily buildings, the right upgrade sequence is never obvious from a walkthrough alone. A blower door test plus thermal imaging tells us exactly where your home loses heat and where air leaks concentrate, so every dollar you spend afterward goes to the right problem. Our Home Energy Audit hub covers the test sequence and reporting.
Blower Door Test
Signs you need it
Persistent drafts, window condensation, or heating bills that don’t respond to thermostat adjustments in a Yonkers home all suggest air leakage that a blower door test will quantify.
What it costs in Yonkers
A standalone blower door test in Yonkers typically runs $250 to $500, and it’s included when you book a full home energy audit with us.
How we do it
We mount a calibrated fan in an exterior door frame, depressurize the house, and measure airflow at 50 pascals. The resulting number gives us a baseline air leakage rate and lets us locate specific leaks.
Thermal Imaging Inspection
Signs you need it
Rooms that feel radically different from each other, or wall sections that stay cold even after the rest of the house warms up, are ideal candidates for infrared scanning.
What it costs in Yonkers
Thermal imaging as part of a Yonkers energy audit typically adds $150 to $300 to the audit cost, depending on home size and scan scope.
How we do it
We scan interior and exterior surfaces with an infrared camera during the blower door test. Cold or hot anomalies show missing insulation, air leaks, and thermal bridging in real time.
What Home Energy Audit Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Full home energy audit | $400 – $800 |
| Blower door test alone | $250 – $500 |
| Thermal imaging add-on | $150 – $300 |
| Duct leakage test | $200 – $450 |
Does a Yonkers energy audit qualify me for NYSERDA incentives?
Yes. A documented audit with blower door test results is often the required first step for NYSERDA-subsidized insulation retrofits in Yonkers. We can tell you exactly which programs apply to your home type. Call (855) 657-3403 for a home-specific answer.
How long does a home energy audit take in Yonkers?
A full audit takes two to four hours, depending on home size and construction type. Row houses are usually faster; balloon-frame homes with complex attics take longer. You get the report within days.

FAQs About Insulation in Yonkers, NY
How quickly can you schedule an insulation job here?
We typically schedule Yonkers jobs within a few days of your call and can prioritize attic or crawl space emergencies. Once we’ve seen the space or reviewed photos, we give you a firm start date so you know when the crew arrives.
Does Yonkers follow the same energy code as New York City?
No, Yonkers falls under New York State code and NYSERDA incentive programs rather than New York City’s separate energy rules, which changes what retrofit work can qualify for. We confirm current state and local requirements before starting and handle any paperwork on our end.
How does the written estimate process work?
We inspect your attic or crawl space in person, measure square footage, and check for access or removal issues, then hand you a written price before any work starts. That price stays fixed once we’re on site unless you add work.
Which nearby areas do you cover besides Yonkers?
Beyond Yonkers, we regularly work in Houston, Spring, The Woodlands, Katy, Pearland, and Humble. If you’re in any of these areas, we can typically get a crew out on a similar timeline to a job here.
What happens to the old insulation you remove?
We bag and haul away everything we remove from your attic or crawl space, including contaminated or vermiculite material handled under proper protocols by our crew. New insulation only goes in after the old material and debris are fully cleared out.

What Yonkers Customers Say
"Solid work on the spray foam in the rim joists and the garage ceiling. Scheduling slipped a day because of rain, which they called about ahead of time. Would use them again."
- Tom Reinholt"Crawl space smelled musty and the floors were cold. Full encapsulation with the thick liner taped at every seam, and a dehumidifier sized for the space. The hygrometer they left reads 48 percent now instead of the 70s."
- Elena Vasquez"The estimate had every line itemized - removal, sealing, baffles, the blown-in by the bag - and the final invoice matched it exactly. Two other companies quoted a single number and could not tell me what R-value they were installing."
