Insulation in Yonkers, NY
Crawl space encapsulation and vapor barrier work in Yonkers runs $2,800-$9,400 for a typical 900-1,500 sq ft space, with older pre-1940 homes on the southwest side usually landing at the higher end because of shallow, damp, rubble-stone foundations. Spray foam insulation for Yonkers attics and rim joists typically costs $2,100-$6,800 depending on the square footage and foam type. If you’re in a Nodine Hill row house or a Crestwood cape, call (866) 751-4428 for a straight answer and a free estimate.
Why Yonkers Homes Are Different
Yonkers is dominated by pre-1940 attached row houses, balloon-frame two- and three-families, and unreinforced masonry apartment buildings, especially in dense southwest neighborhoods like Getty Square, Nodine Hill, and Chicken Island. These buildings went up before wall insulation was a code requirement, and most still have their original horsehair plaster over empty stud cavities. East-side ranch and cape-cod homes from the 1940s through 1970s are a different story, but plenty of those attics contain vermiculite that has to be tested for asbestos before any insulation upgrade can happen.
The terrain matters too. Yonkers rises steeply from the Hudson River waterfront to 350-400 feet inland, and that climb creates real wind-driven moisture on west-facing facades. Riverfront and hillside buildings need vapor management and air-sealing done differently than what you’d spec for a flat inland Westchester town. A house a few blocks from the water deals with conditions a house in White Plains never sees. For the old attached stock in particular, dense-pack cellulose blown through drilled holes in plaster walls is the only workable retrofit, and it’s a technically specialized job.
Our Main Yonkers Services
The two calls we get most from Yonkers homeowners are for attic work and dense-pack walls, both driven by the old housing stock and Hudson Valley winters.
Attic Insulation in Yonkers
Attics in Yonkers run the full range: open bays in 1920s row houses, cramped kneewall spaces in 1950s capes, and flat roof cavities in converted two-families. What they share is heat loss in January and baked top floors in July. We inspect the existing insulation, check for vermiculite that needs testing, and build the attic up to proper R-value. For the full breakdown, see our dedicated page on Attic Insulation in Yonkers.

Crawl Space Encapsulation & Vapor Barrier in Yonkers
Crawl space encapsulation in Yonkers typically runs $2,800-$9,400 for a full liner, foam board on walls, and sealed vents, with the final number driven by square footage, access, and how wet the grade is. Many older Yonkers homes have rubble-stone or unvented crawl foundations that stay damp from fall through spring, feeding musty air into the first floor and making the whole house harder to heat. On the hillside streets off Warburton and Riverdale Avenues, runoff and wind-driven moisture make vapor control the single most important step in the building. We spec these jobs one house at a time, and you can read the full method on our Crawl Space Encapsulation & Vapor Barrier page.
Crawl Space Vapor Barrier
Signs you need it
First-floor floors feel damp or cold through the carpet, you smell earth or must in the living room after rain, or a plastic sheet laid on the dirt floor sweats within hours.
What it costs in Yonkers
A crawl space vapor barrier in Yonkers runs $1,400-$3,000 for liner, taping, and basic wall overlap in a typical 1,200 sq ft crawl.
How we do it
We clear debris, lay a 12-mil reinforced liner with sealed overlap seams, run it up the foundation walls, and secure it so it won’t float or tear during seasonal water movement.
Crawl Space Encapsulation
Signs you need it
Humidity stays above 65% in the crawl even in dry weeks, insulation on the floor joists is sagging or mold-stained, or heating bills climb every winter without an obvious reason.
What it costs in Yonkers
Full crawl space encapsulation in Yonkers runs $4,000-$8,000 including vapor barrier, wall insulation, sealed vents, and a dehumidifier-ready layout.
How we do it
We seal vents and rim joists, install the liner up the walls, add foam board or spray foam to the foundation walls, and leave the space dry enough that condensation stops forming on joists.
Crawl Space Moisture Control
Signs you need it
You see efflorescence on foundation walls, standing water after storms, or rust on the furnace base and water heater legs in the crawl.
What it costs in Yonkers
Standalone moisture control work in Yonkers runs $800-$2,400 for drainage matting, a sump pump, or sealing around the sill plate, depending on the problem.
How we do it
We fix the water path first: grade or drainage corrections outside, sill-sealing inside, then the moisture control system goes in so the space stays dry.
What Crawl Space Encapsulation & Vapor Barrier Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Crawl space vapor barrier | $1,400-$3,000 |
| Full crawl space encapsulation | $4,000-$8,000 |
| Crawl space insulation (floor joists or walls) | $1.50-$3.50/sq ft |
| Moisture control (sump, drainage, sealing) | $800-$2,400 |
Does encapsulating a crawl space in Yonkers help with heating costs?
Yes, and it usually shows within one winter. Stopping damp air from cycling through the joist bays lets the first floor hold heat better, so the furnace doesn’t fight moist, cold air. Call us for a walk-through.
Can you encapsulate a rubble-stone crawl space in an old Yonkers house?
Yes. These foundations are uneven, so we build the liner with extra slack and mechanical fastening rather than relying on a perfect wall surface. It’s common work in Getty Square and Nodine Hill homes.
Spray Foam Insulation in Yonkers
Spray foam in Yonkers runs $2,100-$6,800 for typical attic and rim joist jobs, with closed-cell running higher than open-cell and more per board foot. In old Yonkers houses with no existing wall insulation, spraying the rim joist and attic floor stops the biggest heat leak first, before we talk about walls. That’s worth knowing because the steep Yonkers streets put west-facing walls under real wind pressure from October through March. Read the full process on our Spray Foam Insulation hub page.
Open-Cell Spray Foam
Signs you need it
Attic bedrooms won’t hold heat in winter, the top floor gets muggy in July, or your current insulation sits barely above the joists and you can feel cold air moving through the hatch.
What it costs in Yonkers
Open-cell spray foam in Yonkers attics and floors runs $1.00-$2.50 per board foot installed, with most attic decks landing between $2,000 and $4,500.
How we do it
We prep and mask, spray to the spec’d depth, then trim and confirm coverage before the foam fully cures, keeping the install clean enough that the attic stays usable.
Closed-Cell Spray Foam
Signs you need it
Your crawl space walls sweat, you need structural racking strength in addition to insulation, or you want a vapor barrier built into the insulation layer.
What it costs in Yonkers
Closed-cell spray foam runs $1.75-$4.00 per board foot in Yonkers, with crawl space and rim joist jobs typically $2,500-$6,800 depending on square footage and access.
How we do it
We spray in lifts to control temperature and adhesion, build the required thickness, and leave a hard, moisture-resistant layer that performs as vapor control on its own.
What Spray Foam Insulation Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Open-cell attic or floor | $1.00-$2.50 per board foot |
| Closed-cell (rim joist, crawl walls) | $1.75-$4.00 per board foot |
| Typical rim joist only | $2,100-$4,200 |
| Full attic roof deck | $3,800-$6,800 |
Is spray foam worth it in an old Yonkers row house?
For rim joists and attic floors, yes, usually the best dollar-for-dollar fix. For party walls between attached homes, dense-pack cellulose is often the better value. We’ll tell you which makes sense after one look.
Can you spray foam a finished attic without removing the sheetrock?
Sometimes, if there’s enough access behind kneewalls or from the roof side. In Yonkers capes with tight kneewall spaces, we often combine spray foam on the roof deck with blown-in insulation on the floor. Call for an inspection.
Blown-In Insulation in Yonkers
Blown-in insulation in Yonkers attics runs $1,600-$4,800, and dense-packing the exterior walls of a typical row house runs $2,500-$6,500. The old Yonkers housing stock was built with empty stud cavities, and blowing insulation through a drilled hole grid is the only practical retrofit for plaster walls in Nodine Hill, Chicken Island, and South Broadway. A misread balloon-frame fire stop can leave a whole stud bay unfilled, so marking those stops first is non-negotiable on our jobs. More detail is on the Blown-In Insulation page.
Blown-In Cellulose
Signs you need it
Rooms stay cold in winter with the heat running, doors feel drafty along the floor, or your attic insulation has settled into a thin mat that barely covers the joists.
What it costs in Yonkers
Blown-in cellulose in a Yonkers attic runs $1,800-$3,400 for a typical 1,200-1,500 sq ft space brought up to R-38 or R-49.
How we do it
We run hoses into the attic, blow in lifts to prevent settling, and take density readings as we go so the final R-value is real, not estimated.
Dense-Pack Wall Insulation
Signs you need it
Exterior walls feel cold to the touch in January, you can hear street noise through solid walls, or room temperatures vary sharply between interior and perimeter rooms.
What it costs in Yonkers
Dense-pack wall insulation in Yonkers runs $2,500-$6,500 for exterior walls of a typical two-story row house, including patching and cleanup.
How we do it
We drill a grid of small holes through siding or plaster, blow cellulose at density until the cavity is fully packed, then patch so the home looks untouched.
Blown-In Top-Up
Signs you need it
Your attic has some insulation but it’s below R-30, shows uneven settling, or the upstairs runs hotter than the rest of the house in summer.
What it costs in Yonkers
An attic top-up in Yonkers runs $900-$2,000 for most homes, adding 6-10 inches over existing material to reach total R-49.
How we do it
We inspect the existing layer, add new blown material to spec, and confirm coverage depth with marked gauges before we pack up.
What Blown-In Insulation Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Attic blown-in cellulose | $1,800-$3,400 |
| Dense-pack walls (two-story row house) | $2,500-$6,500 |
| Attic top-up | $900-$2,000 |
| Blown-in fiberglass | $1,600-$4,800 |
Will dense-pack cellulose work behind horsehair plaster in Yonkers?
Yes, and that’s the standard method for these pre-1940 Yonkers homes. The plaster holds fine when the cavity is packed correctly, and the drilled holes patch cleanly so the walls look no different after the job.
How do you know you’re not missing a stud bay in a balloon-frame wall?
We check for fire stops and cavity depth with a borescope before drilling, and we mark each bay during the job. That’s the step that saves a Yonkers homeowner from paying for a wall that still leaks heat.
Radiant Barrier Installation in Yonkers
Radiant barrier installation in Yonkers attics runs $1,200-$3,200 for a typical 1,000-1,500 sq ft roof deck, depending on access and whether it’s stapled to rafters or laid over insulation. In Yonkers summers, attics in those 1950s and 1960s east-side capes can hit 140 degrees, and a radiant barrier cuts the heat that radiates down through the ceiling. That’s a real difference for second-floor bedrooms in Colonial Heights and Crestwood. See the full rundown on our Radiant Barrier Installation page.
Attic Radiant Barrier
Signs you need it
Upstairs rooms stay hot after sunset in July, the attic feels like an oven when you go up there, or your AC runs constantly on afternoons when the temperature sits above 85.
What it costs in Yonkers
An attic radiant barrier in Yonkers runs $1,200-$2,800 for stapled rafter installs in a 1,200 sq ft attic.
How we do it
We staple reinforced foil to the underside of the rafters, keeping a 1-inch air gap against the roof deck so the barrier reflects instead of conducting heat.
Radiant Barrier & Ventilation
Signs you need it
Attic heat builds even with soffit and ridge vents in place, or condensation shows up on the roof deck in winter because trapped heat is melting the snow line unevenly.
What it costs in Yonkers
A radiant barrier paired with balanced ventilation in Yonkers runs $1,800-$3,200, including intake and exhaust corrections.
How we do it
We install the barrier after confirming that soffit intake and high exhaust are balanced, so the attic actually cools instead of just trapping heat with a shiny ceiling.
What Radiant Barrier Installation Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Attic rafter radiant barrier | $1,200-$2,800 |
| Radiant barrier over existing insulation | $800-$1,800 |
| With balanced ventilation work | $1,800-$3,200 |
| Combined with attic air sealing | $2,800-$5,500 |
Does a radiant barrier work in Yonkers winters too?
It helps some, but the bigger winter win in Yonkers is air sealing and insulation at the attic floor. The radiant barrier is mostly a summer upgrade. We’ll scope both together since the attic is open anyway.
Can you install a radiant barrier in an old Yonkers attic with no ridge vent?
We can, but ventilation has to be corrected first or the barrier underperforms. In old Yonkers attics with gable vents only, we often add ridge or box vents as part of the radiant barrier job.
Insulation Removal & Replacement in Yonkers
Insulation removal and replacement in Yonkers attics runs $1,800-$4,600 depending on square footage, contamination, and whether vermiculite is present and needs asbestos testing before anything moves. Pre-1940 and mid-century Yonkers homes frequently contain vermiculite insulation, and because testing and removal protocols are legally specific, this is not a job to improvise. Old squirrel or raccoon nesting in attics is also common in the dense neighborhoods around chicken coops and mature trees. See the full breakdown on our Insulation Removal & Replacement page.
Attic Insulation Removal
Signs you need it
The existing insulation is compressed, mold-stained, or filled with rodent droppings, or the attic smells bad enough that air sealing can’t fix it.
What it costs in Yonkers
Attic insulation removal in Yonkers runs $1,800-$3,500 for a typical 1,200 sq ft attic, not including new insulation.
How we do it
We vacuum out the old material with HEPA-filtered equipment, dispose of it properly, and leave the attic clean and ready for new insulation or air sealing.
Vermiculite & Old Insulation Removal
Signs you need it
Your attic contains vermiculite, the old material has visibly settled or degraded, or you’re planning to sell and know the home inspector will flag it.
What it costs in Yonkers
Vermiculite removal in Yonkers runs $2,500-$4,600 including testing, contained removal, disposal, and cleanup.
How we do it
We test first. If asbestos is present, removal happens under containment with negative air pressure and vacuum bagging. We don’t cut corners on this in Yonkers.
Insulation Replacement
Signs you need it
Rooms nearest the attic are consistently colder than the rest of the house, the existing insulation is missing in spots, or it’s been soaked by a roof leak.
What it costs in Yonkers
Replacement insulation for a Yonkers attic runs $1,600-$4,200, air sealing included on most jobs.
How we do it
After removal and any repairs, we air seal the attic floor, then blow in new material to the target R-value with the same HEPA-contained process.
What Insulation Removal & Replacement Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Basic attic insulation removal | $1,800-$3,500 |
| Vermiculite testing & removal | $2,500-$4,600 |
| Contaminated insulation removal | $2,000-$4,200 |
| Full replacement (removal + new insulation) | $2,800-$6,800 |
Do I need to test vermiculite before removing it in Yonkers?
Yes, always. Vermiculite in Yonkers homes from roughly the 1940s through the 1970s can contain asbestos, and proper testing must happen before any disturbance. Call us and we’ll handle the test as part of the job.
Will you remove insulation with rodent droppings?
Yes, with full protective equipment and HEPA containment. Rodent-contaminated insulation in Yonkers attics is common, and leaving it in place is a health risk. Call (866) 751-4428 for a walk-through.
Attic Air Sealing in Yonkers
Attic air sealing in Yonkers runs $900-$2,800 for a typical 1,000-1,500 sq ft attic, including sealing top plates, penetrations, and the hatch. Old Yonkers homes leak air through the attic floor at every wire penetration, plumbing chase, and light fixture, and sealing those paths before adding insulation is the difference between a house that holds heat and one that leaks through every seam. In pre-1940 row houses and capes, this is the highest-value prep work we do. The full method is on our Attic Air Sealing page.
Attic Floor Air Sealing
Signs you need it
Upstairs rooms stay drafty with insulation already in place, or you notice dust streaks in the insulation (a sign of moving air) when you look in the attic.
What it costs in Yonkers
Attic floor air sealing in Yonkers runs $900-$1,800 for a typical 1,200 sq ft attic, materials included.
How we do it
We pull back insulation, seal every seam, chase, and gap with foam and sealant, then put the insulation back at full depth.
Can Light & Duct Boot Sealing
Signs you need it
Recessed can lights are warm to the touch when off, ceiling-mounted ducts sweat in summer, or you feel cold air dribbling from around ceiling fixtures.
What it costs in Yonkers
Sealing can lights and duct boots in Yonkers runs $300-$900 for a typical home, depending on how many lights and boots exist.
How we do it
We use rated covers and mastic-sealed boots around each light and duct connection, keeping the fire code and airflow requirements straight.
Attic Hatch Sealing
Signs you need it
The attic hatch or pull-down ladder feels cold to the touch, or you can feel warm air escaping when you open the stair door in winter.
What it costs in Yonkers
Attic hatch sealing in Yonkers runs $200-$500 including weatherstripping, an insulated cover, and drywall panel work if needed.
How we do it
We weatherstrip the hatch or stair frame and install an insulated cover that closes the thermal hole at the top of the house.
What Attic Air Sealing Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Full attic floor air sealing | $900-$1,800 |
| Can light & duct boot sealing | $300-$900 |
| Attic hatch sealing | $200-$500 |
| Air sealing + new blown-in insulation | $2,400-$5,600 |
Is attic air sealing worth it if I’m not adding insulation?
Usually, yes, because the sealing itself cuts the airflow that makes the existing insulation underperform. In Yonkers houses with old plaster ceilings, the difference after sealing is often bigger than adding R-value alone. Call us for a straight read.
Can you air seal a finished attic in Yonkers?
We can often seal from beneath through the accessible kneewall spaces and the attic floor around the hatch. Full floor sealing usually needs the insulation pulled back, so we’ll scope what’s reachable. Call us.
Wall Insulation in Yonkers
Wall insulation in Yonkers runs $2,500-$6,500 for dense-pack drilling and fill on a typical two-story row house, with injection foam running higher at $4,000-$9,000 for a full exterior wall package. Most Yonkers row houses and two-families from the 1900-1940 era have no wall insulation at all, and the only realistic retrofit is drilling a grid through the plaster or siding, packing the cavity, and patching clean. You can’t finesse this with batts, and anybody who tells you otherwise hasn’t worked inside a Nodine Hill house. The full process is on our Wall Insulation hub page.
Drill & Fill Wall Insulation
Signs you need it
Exterior walls are cold to the touch, the thermostat fights every winter, and you can feel a draft along the baseboards on windy days.
What it costs in Yonkers
Drill & fill wall insulation in Yonkers runs $2,500-$6,500 for a two-story exterior, patching included.
How we do it
We drill a clean grid from the outside or inside, pack each cavity with cellulose at density, and patch so the walls look like the day before we started.
Injection Foam Wall Insulation
Signs you need it
Walls have persistent moisture spots, you want an air seal combined with insulation, or noise from the street penetrates the house despite new windows.
What it costs in Yonkers
Injection foam wall insulation in Yonkers runs $4,000-$9,000 for a full exterior wall package on a typical attached home.
How we do it
We inject slow-rise foam through small holes that fills the cavity as it expands, sealing seams and providing insulation in one pass, with lower moisture retention than cellulose in high-exposure walls.
What Wall Insulation Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Drill & fill cellulose walls | $2,500-$6,500 |
| Injection foam wall insulation | $4,000-$9,000 |
| Interior wall soundproofing | $1,800-$3,600 |
| Exterior wall insulation under siding | $2.50-$5.00/sq ft |
Can you insulate the walls of an attached Yonkers row house without ripping out the plaster?
Yes. Drill and fill through interior plaster or exterior siding keeps the original walls intact, and the patched holes disappear. This is the standard approach for pre-1940 Yonkers rowhouses. Call us for an inspection.
Why doesn’t batt insulation work for old Yonkers walls?
Batt insulation only works when you can open the entire cavity, which means pulling off plaster or siding. Most Yonkers homeowners don’t want that, and dense-pack cellulose compacts better into the uneven old framing. Call us and we’ll show you the difference.
Attic Cleaning & Rodent Proofing in Yonkers
Attic cleaning and rodent proofing in Yonkers runs $900-$3,400 depending on the attic’s condition, contamination level, and how many entry points need closing. Older Yonkers homes with mature trees and attached garages see recurring squirrel, rat, and mouse pressure, especially near the parks and wooded blocks along the east side. Droppings and urine-soaked insulation are a real health issue, not just a smell problem, so we treat cleanup and exclusion as one job. The full process is on our Attic Cleaning & Rodent Proofing page.
Attic Cleanout
Signs you need it
You hear scratching above the ceiling at night, smell ammonia in the upstairs hallway, or find droppings and shredded material when you check the attic.
What it costs in Yonkers
An attic cleanout in Yonkers runs $900-$2,200 for a typical 1,200 sq ft attic with moderate droppings, not including new insulation.
How we do it
We remove contaminated insulation and debris under HEPA containment, then vacuum and prep the space for sanitizing or new insulation.
Rodent Proofing & Exclusion
Signs you need it
You’ve had rodents come back after trapping, find chewed wires or shingles, or notice daylight entering around the roofline from inside the attic.
What it costs in Yonkers
Rodent proofing and exclusion in Yonkers runs $1,200-$2,800 for most attics, including sealing all entry points and installing permanent guards.
How we do it
We seal every roof gap, vent, and soffit gap with chew-proof materials, install guards where needed, and do a final inspection walk so nothing is missed.
Attic Sanitizing & Decontamination
Signs you need it
The attic has a strong odor after removal, urine stains are visible on the floor boards, or you’re prepping to sell and want the space genuinely clean.
What it costs in Yonkers
Attic sanitizing and decontamination in Yonkers runs $1,500-$3,400 including enzyme treatment and odor sealing.
How we do it
We apply enzyme treatments to break down urine and odor compounds, then seal the affected surfaces and ventilate the space so it’s dry and clean, not masked.
What Attic Cleaning & Rodent Proofing Costs in Yonkers
| Item | Typical range in Yonkers |
|---|---|
| Attic cleanout | $900-$2,200 |
| Rodent proofing & exclusion | $1,200-$2,800 |
| Sanitizing & decontamination | $1,500-$3,400 |
| Full cleanup + new insulation | $2,800-$6,200 |
Will cleaning my Yonkers attic keep rodents out permanently?
Cleanup removes the smell and contamination, but exclusion is what keeps them out. We do both in the same visit so the problem doesn’t come back in a month. Call us for an inspection.
Is rodent-proofing included in your insulation work?
When we’re already in the attic and see entry points, we flag them and seal them as part of the job in most cases. If the infestation is recent, full exclusion gets scoped separately. Call (866) 751-4428 with what you’re seeing.

Home Energy Audit in Yonkers
A home energy audit in Yonkers runs $400-$900 for the full blower-door and thermal imaging package, and most utility rebate programs around Westchester reduce that further if insulation work follows. In old Yonkers houses with balloon framing, no wall insulation, and original windows, guessing at the right fix wastes money; a blower door test shows exactly where air is moving and which rooms lose the most heat. We run the audit first, then give you numbers, not guesses. The full scope is on our Home Energy Audit page.
Blower Door Test
Signs you need it
Your heating bills are higher than neighbors’ with similar houses, rooms feel drafty in cold weather, or you’ve already added insulation and noticed almost no change.
What it costs in Yonkers
A blower door test in Yonkers runs $400-$600 as part of a full home energy audit, or $250-$400 standalone with a report.
How we do it
We install the door fan, depressurize the house, and measure the air leakage rate so we know how leaky the building actually is before recommending work.
Thermal Imaging Inspection
Signs you need it
Cold spots show up on interior walls in winter, you suspect missing insulation in specific bays, or you want proof of problem areas before spending on repairs.
What it costs in Yonkers
A thermal imaging inspection in Yonkers runs $200-$450 when bundled with the audit, producing a room-by-room thermal map.
How we do it
We scan walls, ceilings, and floors with a thermal camera while the house is under blower-door pressure, so missing insulation and air paths show up clearly.
Duct Leakage Test
Signs you need it
Rooms at the end of the duct run stay cold, the upstairs is much warmer or colder than the downstairs, or air filters clog quickly with dust.

Price depends mostly on attic access in older row houses, how many inches of new material are needed, and whether existing insulation or vermiculite has to be removed and tested first. Crawl space size and wall cavity access factor in on masonry buildings too. The exact number goes in writing before any work begins.
FAQs About Insulation in Yonkers, NY
How quickly can you schedule an insulation job?
Scheduling depends on current demand and the scope of the work. After a quick phone call or an on-site look at the attic, crawl space, or walls involved, we set a start date for the Yonkers job and let you know how long it will take before any work begins.
Do I need a permit for insulation work?
A standard attic or wall insulation job usually doesn’t need a permit, but older homes here with vermiculite attic insulation are a different story. That material has to be tested for asbestos before any insulation work happens, and we handle that testing and any required documentation as part of the job.
How does the written estimate work?
Before any work starts, we walk the attic, crawl space, or walls being insulated and write up the exact scope and price for the Yonkers job in a single document. That number is fixed before any material is opened or any tear-out begins, so there are no surprise add-ons once work is underway.
Which nearby areas do you also cover?
We also work throughout the surrounding area, including Houston, Spring, The Woodlands, Katy, Pearland, and Humble, and Yonkers appointments are scheduled alongside jobs in those communities. If your home falls just outside this list, call and we’ll confirm whether we can reach you.
What happens to my old insulation when you replace it?
We remove old batts, blown-in material, or vapor barrier and bag or vacuum it out for disposal before any new insulation goes in. If it’s contaminated with rodent droppings, mold, or moisture damage, we handle it separately with sanitizing before the space is sealed and refilled.

What Yonkers Customers Say
"Walt came out himself, stuck his head in the attic, and told me I had about four inches where I needed fourteen. No sales pitch, just the number and what it would cost to fix it. Crew was here two days later."
- Carl Meadows"We had the walls of our old house filled with foam through small holes from the outside. Patched and painted the same afternoon. The bedrooms hold heat now and the furnace runs a lot less."
- Linda Baumgartner"Good honest work on the attic. The price was a little higher than one online quote, but Walt is the one who actually showed up and the one whose name is on the truck, and that was worth it to us."
- Helen Tran
