Insulation in Clifton, NJ
Crawl space encapsulation and vapor barrier work in Clifton usually costs $3.50 to $7.00 per square foot, and most jobs run $4,800 to $13,000 depending on square footage, access, and whether old soaked fiberglass has to come out first. Pricing breaks down by materials (reinforced polyethylene, drainage matting, seam tape, fasteners, and often a dehumidifier), labor, and the prep work that is common near the Passaic River. We are Walt’s Insulation, locally owned and owner-operated since 2000, and a live person answers when you call (866) 751-4428.
Why Clifton Homes Are Different
Clifton exploded with post-WWII construction. Most houses went up between 1945 and 1965: Cape Cods, split-levels, and detached colonials built with what was cheap and available, which meant kraft-faced fiberglass batts and zero air sealing. Those batts have had seventy-plus years to settle, compress, and soak up the humidity that hangs in the Passaic River valley. Walk into a Clifton attic in August and you will feel it: hot, damp, and heavy. In January the same attic is freezing because the insulation has compacted to a fraction of its original R-value.
The river adds a second layer of trouble. Sections of Clifton along the Passaic corridor flood often enough that basement and crawl space insulation gets saturated, the paper facing molds, and the material has to be torn out before anything new can go in. Contractors who quote an attic-and-rim-joist job here frequently discover the real job is a basement mold remediation with insulation replacement attached. Two-family homes scattered through town compound the problem: shared attics, shared walls, and multiple thermal boundaries that a one-size-fits-all approach cannot handle. The dispatch and scheduling side of our operation coordinates from the brand’s New York City office, but the crews who show up at your Clifton door are local and know the housing stock.
Our Main Clifton Services
Two services get the most calls from Clifton homeowners: attic insulation and crawl space encapsulation. Here is what each job looks like in this city.
Attic Insulation in Clifton
Clifton attics are almost always warmer than the living floor below in summer and colder in winter, and the cause is usually sixty-year-old batts that have settled into the joist bays. We remove the old material where needed, air seal the top plates and penetrations, and blow in fresh insulation to the right depth for the Passaic River valley climate, which means handling both heat loss and summer moisture. Homeowners on streets like Valley Road, Broad Street, and the neighborhoods off Ackerman Avenue call when bedroom temperatures swing ten degrees between floors. That is a classic sign the attic thermal boundary has failed. We use brands like Owens Corning and GreenFiber, and every job carries the Done Right Promise: if it’s not done right, we make it right, no runaround. See our dedicated Attic Insulation in Clifton page for full details.

Crawl Space Encapsulation & Vapor Barrier in Clifton
Crawl space encapsulation in Clifton typically runs $4,800 to $13,000, and the price is driven by how much water has already found its way in. Clifton sits in the Passaic River valley, ground moisture stays elevated, and homes along the flood corridor often have saturated fiberglass batts and mold-colonized paper facings that have to be removed before a new vapor barrier goes down. Skipping that step means the new liner traps moisture against the sill plate and the whole job fails within a season. This is the service we recommend most for Clifton homeowners with dirt-floor crawl spaces, musty first-floor smells, and rising energy bills. Learn about our process on the Crawl Space Encapsulation & Vapor Barrier hub.
Crawl Space Vapor Barrier
Signs you need it
Standing water after heavy rain, visible moisture on the crawl space walls, or a damp smell that seeps into the first floor.
What it costs in Clifton
A reinforced vapor barrier for a typical Clifton crawl space runs $3.50 to $5.00 per square foot installed.
How we do it
We remove old, wet material, level the floor where needed, and install a reinforced polyethylene liner sealed at all seams, piers, and the sill plate with mechanical fasteners and seam tape.
Crawl Space Encapsulation
Signs you need it
High indoor humidity in summer, condensation on ductwork, mold growth on floor joists, or insulation falling from the floor assembly.
What it costs in Clifton
Full encapsulation for a Clifton crawl space runs $5.00 to $7.00 per square foot, including liner, wall coverage, and fasteners.
How we do it
We seal the entire crawl space: liner on the floor and up the walls, seam tape at every junction, and closed-cell spray foam at the rim joist and sill plate to stop thermal transfer and outside air.
Crawl Space Insulation
Signs you need it
Cold floors in winter directly above the crawl space, frozen pipes in January, or heat that never seems to reach the far rooms.
What it costs in Clifton
Insulating the crawl space after encapsulation runs $3,000 to $8,000 for a typical Clifton home, depending on square footage and access.
How we do it
Once the area is dry and sealed, we install closed-cell spray foam on the foundation walls or rim joist, which handles both the thermal layer and the air barrier in one step.
What Crawl Space Encapsulation & Vapor Barrier Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Vapor barrier installation | $3.50 - $5.00 per sq ft |
| Full encapsulation | $5.00 - $7.00 per sq ft |
| Total project (typical 800 - 1,500 sq ft) | $4,800 - $13,000 |
| Additional insulation after encapsulation | $3,000 - $8,000 |
Is it cheaper to just replace wet insulation instead of encapsulating?
Not in Clifton. Replacing wet fiberglass without fixing the moisture source means the new batts will be moldy again within a season or two. Encapsulation costs more upfront but stops the water, and it is the only response that lasts near the Passaic River. Call (866) 751-4428 for a straight number.
Can you do the job in one day?
Most Clifton crawl space vapor barrier and encapsulation jobs are done in one day, sometimes two when there is standing water, debris, or old insulation to remove first. We will tell you the schedule before work starts. Call for a free estimate and a real date.
Spray Foam Insulation in Clifton
Spray foam insulation in Clifton runs $1.75 to $4.50 per square foot for open-cell and $2.50 to $5.50 for closed-cell, with most attic and rim joist jobs landing between $2,800 and $9,000. Closed-cell is usually the right call here because the Passaic River valley’s humidity and flood risk demand a material that also acts as a moisture barrier. A 1948 Cape Cod in Clifton with only three inches of settled batts is a perfect candidate. See the Spray Foam Insulation service page for deeper material breakdowns.
Rim Joist Spray Foam
Signs you need it
Cold floors at the perimeter of the house in winter, musty air in the basement, or drafts you can feel near the foundation wall.
What it costs in Clifton
A typical Clifton rim joist spray foam job runs $2,800 to $5,000, depending on linear footage and access.
How we do it
We clean the rim joist, remove any wet or moldy fiberglass, and spray closed-cell foam into every bay from the sill plate to the first floor assembly, sealing the air and thermal boundary in one pass.
Attic Spray Foam
Signs you need it
Upstairs rooms that are ten degrees hotter than the first floor in summer, or HVAC equipment in the attic that runs constantly.
What it costs in Clifton
Foaming a Clifton attic roof deck runs $5,000 to $9,000, though cathedral ceilings and tight access push toward the high end.
How we do it
We air seal first, then spray foam directly to the roof deck, turning the attic into conditioned space and removing the stack effect that pulls heat out all winter.
What Spray Foam Insulation Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Open-cell spray foam | $1.75 - $4.50 per sq ft |
| Closed-cell spray foam | $2.50 - $5.50 per sq ft |
| Rim joist spray foam | $2,800 - $5,000 |
| Attic roof deck spray foam | $5,000 - $9,000 |
Which foam is right for a Clifton crawl space?
Closed-cell. In the Passaic River valley’s humid climate, open-cell foam can absorb moisture and lose its R-value quickly. Closed-cell acts as both insulation and vapor barrier, which is exactly what a Clifton crawl space needs. Call (866) 751-4428 and we will give you a straight recommendation.
How long does spray foam last in a Clifton attic?
Thirty to fifty years when installed correctly and kept dry. The bigger issue is installation quality, not material lifespan. A bad job off-gasses, cracks, and loses performance in a few seasons. That is why we back every spray foam job with the Done Right Promise.
Blown-In Insulation in Clifton
Blown-in insulation in Clifton averages $1,700 to $4,500 for a standard attic, depending on square footage, depth, and whether old material needs to come out first. Most of the attics we work in around Clifton still have the original 1960s batts, compacted to maybe R-8 when they were installed as R-19. Blowing new cellulose or fiberglass over the top is the fastest, cleanest fix for a house that cannot hold heat. We install GreenFiber cellulose and Owens Corning fiberglass, cut to the right depth for the valley’s cold winters. Details on materials and process live on the Blown-In Insulation service hub.
Blown-In Cellulose
Signs you need it
Uneven snow melt on the roof in winter, high heating bills, or rooms that differ in temperature from one end of the house to the other.
What it costs in Clifton
Cellulose blown to R-49 in a typical Clifton attic runs $1,700 to $3,500 installed.
How we do it
We air seal the top plates and penetrations first, then blow dense cellulose to the depth that gives you the R-value the climate requires, leveling it across the whole attic floor.
Blown-In Fiberglass
Signs you need it
Old pink batts that have collapsed into the joist bays, or an attic that never had insulation to begin with.
What it costs in Clifton
Blown fiberglass for a Clifton attic runs $1,800 to $4,500 depending on depth and square footage.
How we do it
We remove or treat old material as needed, seal the air bypasses, and blow fiberglass to the target depth, checking with a depth gauge as we go so you get the R-value you paid for.
What Blown-In Insulation Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Blown-in cellulose attic | $1,700 - $3,500 |
| Blown-in fiberglass attic | $1,800 - $4,500 |
| Blown-in top-up (over existing batts) | $1,200 - $2,800 |
| Dense-pack wall insulation | $1,600 - $3,200 |
Can you blow insulation over old batts in a Clifton attic?
Sometimes. If the old batts are dry and not moldy, blowing new material over them is effective and saves the cost of removal. If they are damp or rodent-damaged, they come out first. We will tell you honestly which applies to your attic. Call for a free assessment.
How much R-value do I need in a Clifton attic?
R-49 is the standard for attics in northern New Jersey’s climate. Most Clifton attics we see are at R-8 to R-15. Bringing them to R-49 is the single biggest energy upgrade most homes here will ever get. Call (866) 751-4428 and we will measure your current depth for free.
Radiant Barrier Installation in Clifton
Radiant barrier installation in Clifton runs $1,500 to $4,200 for a typical attic, and the value is summer cooling, not winter warmth. Clifton attics hit 130 degrees in July simply because the sun bakes the roof deck all day and the old fiberglass does almost nothing to reflect that heat back out. A foil radiant barrier attached to the rafters blocks most of that radiant heat gain, letting the attic stay closer to outdoor temperature and lightening the load on your air conditioner. Our crews install reflective foil and the right ventilation, sized for the Passaic River valley’s hot, humid summers. See the Radiant Barrier Installation hub for material options.
Attic Radiant Barrier
Signs you need it
Second floor bedrooms that are still hot at midnight, an attic that feels like an oven when you open the hatch, or an AC unit that runs from noon to midnight in July.
What it costs in Clifton
A radiant barrier for a standard Clifton attic runs $1,500 to $3,000, installed to the rafters.
How we do it
We staple or fasten the reflective foil to the underside of the rafters, leaving a small air gap, and make sure soffit and ridge ventilation are working so heat actually escapes.
Radiant Barrier & Ventilation
Signs you need it
Ice dams in winter, mold on the roof sheathing, or high summer attic heat with only passive gable vents.
What it costs in Clifton
Adding a radiant barrier plus ventilation upgrades in a Clifton attic runs $2,500 to $4,200.
How we do it
We install the barrier, then size and add soffit vents, a ridge vent, or a solar-powered attic fan so the reflected heat has somewhere to go.
What Radiant Barrier Installation Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Attic radiant barrier | $1,500 - $3,000 |
| Radiant barrier + ventilation | $2,500 - $4,200 |
| Roof deck radiant barrier (with re-roof) | $2,000 - $3,500 |
| Energy audit + radiant barrier package | $2,200 - $4,000 |
Will a radiant barrier help a Clifton home in winter?
Modestly. The main payoff is summer, when attic heat drives up cooling costs. In winter it reflects some heat back down, but if your main problem is January heating bills, air sealing and insulation matter more. Call (866) 751-4428 and we will tell you what your attic actually needs.
Do I need ventilation if I add a radiant barrier?
Yes. A radiant barrier without adequate ventilation just moves the heat around inside the attic. In Clifton’s humid summers, trapped heat accelerates shingle wear and can create condensation. We check venting before installing any barrier.
Insulation Removal & Replacement in Clifton
Insulation removal and replacement in Clifton runs $1.50 to $3.50 per square foot for the removal labor, with full attic jobs landing between $2,900 and $6,500 when new material goes back in. The Passaic River corridor is the reason we hear about this so often from Clifton: flood-soaked batts, rodent nests, and decades of roof leaks have turned what was originally a simple top-up into a full tear-out. Paper facing that has been wet for years grows mold, and no amount of new insulation makes mold go away. The Insulation Removal & Replacement hub explains our process step by step.
Contaminated Insulation Removal
Signs you need it
Visible rodent droppings in the attic, a musty smell you cannot trace, or dark staining on the existing insulation from years of moisture.
What it costs in Clifton
Removing moldy or rodent-contaminated insulation in a Clifton attic runs $1.50 to $3.00 per square foot.
How we do it
We contain the workspace, remove the contaminated material with commercial vacuums, sanitize the surfaces, and haul everything away. Then we inspect for entry points before any new material goes in.
Attic Insulation Removal & Replacement
Signs you need it
Insulation that has collapsed to the bottom of the joist bays, water stains on the ceiling below, or years of deferred maintenance that left the attic uninsulated in spots.
What it costs in Clifton
A full removal and replacement for a standard Clifton attic runs $2,900 to $6,500, depending on size and material choice.
How we do it
We remove all old material, air seal, treat any mold, and blow in fresh cellulose or fiberglass to the target R-value, usually R-49 for this climate.
What Insulation Removal & Replacement Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Insulation removal labor | $1.50 - $3.50 per sq ft |
| Contaminated removal | $1.50 - $3.00 per sq ft |
| Full attic removal & replacement | $2,900 - $6,500 |
| Vermiculite removal (testing required) | $3,000 - $7,000 |
Can you remove old insulation if I have vermiculite?
We can, but vermiculite requires testing for asbestos first under New Jersey regulations. In older Clifton homes, vermiculite is common. We will guide you through the testing and containment process before anyone touches the material. Call for a straight explanation.
How long does a full attic removal take in Clifton?
Most Clifton attic removals are done in one day, sometimes two when the material is heavily contaminated or the attic access is tight. The replacement goes in on the same visit. Call (866) 751-4428 for a schedule based on your square footage.
Attic Air Sealing in Clifton
Attic air sealing in Clifton typically costs $900 to $2,500 for a full top-plate and penetration job, and it is the highest-value energy upgrade most homeowners never think about. Your Clifton Cape Cod was built when air sealing meant nothing: top plates are open to the attic, can lights leak like chimneys, and the hatch sits unsealed while heated air pours out all winter. Sealing those bypasses before adding insulation is how you fix cold first-floor rooms and a furnace that runs nonstop. Our work follows the Attic Air Sealing process from inspection to final verification.
Attic Floor Air Sealing
Signs you need it
Cold air falling from the attic hatch in winter, dust streaks on the insulation, or rooms that never hold heat.
What it costs in Clifton
A full air sealing job for a Clifton attic floor runs $900 to $2,500, depending on the number of penetrations.
How we do it
We pull back existing insulation, seal every top plate, wire penetration, and chase with foam or caulk, then lay the insulation back and top it up to target depth.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights that glow with dust around the trim, or rooms that lose heat around ceiling fixtures.
What it costs in Clifton
Sealing can lights and duct boots in a Clifton home runs $400 to $900 as a standalone, less when bundled with a full attic job.
How we do it
We install sealed covers or boxes around non-rated fixtures, foam the gap between the drywall and the fixture, and seal duct boots at the ceiling plane so conditioned air stays in the room.
What Attic Air Sealing Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Full attic air sealing | $900 - $2,500 |
| Can light & duct boot sealing | $400 - $900 |
| Attic hatch sealing | $200 - $500 |
| Air sealing + insulation package | $2,000 - $5,000 |
Does air sealing really make a difference in a Clifton home?
More than most people expect. A well-sealed attic can cut heating loss by 10 to 20 percent, and in Clifton’s single-digit January nights that is real money. Sealing without adding insulation still helps, but doing both is the strongest fix. Call for an attic inspection and we will show you where the leaks are.
Can I do the air sealing myself first and insulate later?
You can, but most homeowners underestimate how many penetrations exist in a 1950s Clifton attic. The work involves working in tight, dusty spaces and knowing what can be sealed and what needs venting. We recommend a trained technician. Safety first, and the job gets done right.
Wall Insulation in Clifton
Wall insulation in Clifton usually means drill-and-fill or injection foam for existing homes, and typical jobs run $1,600 to $3,800 depending on house size and wall construction. Most Clifton houses built before 1965 went up with empty wall cavities or a thin layer of useless kraft-faced batt. The exterior walls are the largest thermal boundary in the house, and an uninsulated wall leaks heat all winter while holding humidity in the summer. That is why we hear from so many Clifton homeowners whose heating bills keep climbing even after they fix the attic. See the Wall Insulation hub for a full comparison of methods.
Drill & Fill Wall Insulation
Signs you need it
Rooms that never stay warm, walls that feel cold to the touch in winter, or heating bills that keep rising after attic work.
What it costs in Clifton
Drill and fill for an average Clifton home runs $1,600 to $3,800, depending on wall area and material.
How we do it
We drill small access holes from outside, blow dense-pack cellulose or fiberglass into every stud cavity, then patch and repaint the holes to match.
Injection Foam Wall Insulation
Signs you need it
Walls with existing insulation that has settled, or homes with awkward cavity sizes that make dense-pack difficult.
What it costs in Clifton
Injection foam for a Clifton ranch or Cape Cod runs $2,500 to $5,500, depending on size and access.
How we do it
We inject slow-rise foam through small holes at the top, middle, and bottom of each cavity, monitoring fill as it expands to avoid over-packing the wall.
What Wall Insulation Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Drill & fill wall insulation | $1,600 - $3,800 |
| Injection foam wall insulation | $2,500 - $5,500 |
| Exterior wall insulation (new siding) | $4,000 - $9,000 |
| Interior wall soundproofing | $1,200 - $3,000 |
Can you insulate the walls of a two-family Clifton home?
Yes, and it is one of the more common jobs we do in Clifton’s two-family houses. The shared wall and the party wall both need attention, and we work around the occupied units carefully. Call (866) 751-4428 to schedule an inspection of both units’ thermal boundaries.
Is it cheaper to insulate the walls from outside or inside?
From outside is usually less disruptive but costs more because of siding work. Inside work means patching drywall, which costs less but dirties the living area. In Clifton, most homeowners choose drill-and-fill through exterior holes because it avoids interior repairs entirely. We will walk you through both prices.
Attic Cleaning & Rodent Proofing in Clifton
Attic cleaning and rodent proofing in Clifton runs $900 to $2,800 for a thorough cleanout, decontamination, and exclusion work, and it is the service we recommend before any insulation goes back in. Older Clifton neighborhoods with mature trees and two-family homes have steady squirrel, raccoon, and mouse pressure, and those animals turn a clean attic into a biohazard in one nesting season. Rodent droppings and urine soak into insulation and drywall, and you cannot blow new material over that. The full process is covered on the Attic Cleaning & Rodent Proofing hub.
Attic Cleanout
Signs you need it
Scratching sounds at night, droppings visible around the hatch, or insulation that has been tunneled through and compacted.
What it costs in Clifton
A standard Clifton attic cleanout runs $900 to $2,000, depending on the amount of waste and the attic size.
How we do it
We remove all waste and contaminated insulation, vacuum the entire floor and cavities, and dispose of everything through a licensed hauler.
Rodent Proofing & Exclusion
Signs you need it
Chewed wiring, gnaw marks on wood, or daylight visible through gaps at the roofline and soffits.
What it costs in Clifton
Exclusion work around rooflines, soffits, and vents in a Clifton home runs $800 to $1,800, and we recommend it with every cleanout.
How we do it
We find every entry point, seal them with steel mesh, foam, and flashing as needed, and check the entire perimeter before telling you the attic is animal-proof.
What Attic Cleaning & Rodent Proofing Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Attic cleanout | $900 - $2,000 |
| Rodent proofing & exclusion | $800 - $1,800 |
| Sanitizing & decontamination | $800 - $2,000 |
| Full restoration (clean, seal, re-insulate) | $2,800 - $6,000 |
Do I need to clean the attic before blowing in new insulation?
If there has been any rodent activity or water damage, yes. Blowing new insulation over droppings or mold seals the problem in and compounds it. We always inspect before we quote any Clifton attic insulation job so you know what needs to happen first. Call for a free look.
Can you remove raccoons or squirrels?
We do exclusion work, not live trapping. We seal the attic so animals cannot get back in, and we work with licensed wildlife removal partners when an animal is trapped inside. Your call gets a live person who will tell you exactly what to do next.
Home Energy Audit in Clifton
A home energy audit in Clifton costs $200 to $500 for the diagnostic work, and we apply that fee back toward any insulation or air sealing work you approve. For a 1950s Clifton ranch or Cape Cod where the furnace runs all winter and the AC fights the humidity all summer, the audit tells you exactly where the house is losing energy, room by room, boundary by boundary. We find the stack effect, the missing insulation, the leaking ducts, and the thermal holes that make a Clifton house impossible to heat efficiently. Details on what the audit includes are on the Home Energy Audit hub.
Blower Door Test
Signs you need it
High energy bills, drafts you cannot trace, or uneven temperatures from room to room despite a working furnace.
What it costs in Clifton
A blower door test as part of a full Clifton energy audit runs $200 to $500, and that fee is credited toward work we perform.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure total air leakage in CFM. That number drives every recommendation we make.
Thermal Imaging Inspection
Signs you need it
Cold spots on walls or ceilings in winter, or rooms that never reach the thermostat setting.
What it costs in Clifton
A thermal imaging scan in a Clifton home runs $300 to $600 when paired with a blower door test.
How we do it
We scan every wall, floor, and ceiling with a thermal camera to find missing insulation, air leaks, and moisture, then map the findings to specific fixes.
What Home Energy Audit Costs in Clifton
| Item | Typical range in Clifton |
|---|---|
| Blower door test | $200 - $500 |
| Thermal imaging inspection | $300 - $600 |
| Insulation inspection | $150 - $400 |
| Full audit (blower door + thermal + report) | $500 - $1,100 |
Do I need an energy audit before insulating my Clifton attic?
Not always, but it removes the guesswork. An audit shows whether air sealing, wall insulation, or duct leakage matters more than the attic itself. We will tell you if the audit is worth the fee for your house, and the cost comes back off any work you approve. Call (866) 751-4428 for a straight recommendation.
Can you do the audit and the insulation work in the same week?
Usually. We schedule the audit, walk you through the findings, and can start the recommended work within days. Most Clifton homeowners complete the full package within two weeks. Call to set a start date.

FAQs About Insulation in Clifton, NJ
How fast can we get scheduled for insulation work in Clifton?
We schedule most Clifton jobs within one to two weeks of finalizing the estimate, sooner in slower months and a bit longer during the pre-winter and mid-summer rush. A typical attic job takes a single day; full crawl space encapsulation can run one to three days depending on size and access.
Do we need a permit for attic or crawl space insulation in Clifton?
Standard attic insulation and air sealing in Clifton typically don’t require a permit. Homes along the Passaic River corridor that have taken on water may need the affected insulation removed and dried out before any new material goes in, which we assess on-site.
How does the written estimate work before you start?
We inspect the attic, crawl space, or walls in person or from photos you send us, then give you a written estimate with the full scope and price before any work starts. That price doesn’t change once the job begins unless you ask us to add something partway through.
Do you also work outside Clifton?
Yes. Along with Clifton, our crews regularly work in Houston, Spring, The Woodlands, Katy, Pearland, and Humble, so if you own or manage multiple properties across that broader area, we can schedule them together instead of booking separate visits.
What happens to the old insulation you remove?
We bag and haul away insulation that’s failed, wet, moldy, or damaged by rodents as part of the removal cost already listed on your estimate, and we dispose of it properly. We don’t install new material over contaminated insulation without addressing the underlying problem first.

What Clifton Customers Say
"Air sealing first, then blown-in over the top. He found a bathroom fan venting straight into the attic and fixed that too. Written price before they started, same price when they finished."
- Arjun Mehta"Spray foam in the garage ceiling under the bonus room. That room used to be unusable in summer. Walt talked me out of foaming the whole attic because it did not need it - saved me a couple thousand and I trust him more for it."
- Bud Larkin"Crawl space was wet every spring. They laid the heavy liner, sealed the vents, and put a dehumidifier down there. Floors are warm and the moisture meter he left reads fine now. He still answers when I text him a reading."
