Insulation Company in Van Nuys, CA
Blown in insulation is the most common retrofit we handle in Van Nuys, and for good reason: most homes here were built between the 1940s and 1970s with thin, settled fiberglass batts that stopped doing their job a long time ago. When summer attic temperatures push past 150°F and winter nights dip toward freezing, that deteriorated insulation shows up as hot rooms, cold floors, and energy bills that climb every year. We only do insulation, which means our crews know exactly how to correct under-insulated attics in Van Nuys homes without the guesswork. Call (877) 680-3557 for a free estimate.
Why Van Nuys Homes Are Different
Van Nuys sits in the heart of the San Fernando Valley, where insulation has to handle conditions that coastal LA neighborhoods rarely see. Summer highs routinely exceed 100°F, and that heat sits in attics for months, baking whatever insulation is up there. But Van Nuys also gets cold snaps in winter, when overnight temperatures can drop near freezing, especially when the Valley’s inversion layer traps cold air. A home here needs insulation that blocks intense heat for eight months of the year and still holds warmth during those few cold winter weeks. That dual demand is not optional; it is the baseline for any material we recommend.
The housing stock makes this more urgent. Most Van Nuys homes are post-WWII tract houses, typically 1,200 to 1,800 square feet with wood-frame construction and original single-pane windows. Many still have whatever fiberglass batts were installed decades ago, now thin, compressed, and filled with dust. The 1960s and 70s apartment buildings across Van Nuys often have minimal wall insulation and attics that were never revisited after construction. In the flat, sun-baked tracts around neighborhoods like Valley Glen-adjacent Van Nuys, attic temperatures regularly hit 150°F in July and August, which accelerates degradation of standard fiberglass and makes high-R-value blown-in insulation a practical necessity rather than an upgrade. Newer infill townhomes and ADUs do not escape the problem either; many were built to minimum code and leave the same comfort gaps.
Permits for insulation work in Van Nuys are typically straightforward for attics and walls, though any structural changes or electrical work tied to insulation require the proper sign-offs through the city. We handle the insulation scope and can coordinate with your contractor when other trades are involved.
Our Main Van Nuys Services
Two services dominate the calls we get from Van Nuys homeowners: attic insulation and spray foam insulation. Both solve real problems here, but they work differently, and the right choice depends on your home’s construction and where the heat is getting in.
Attic Insulation in Van Nuys
Most Van Nuys attics are under-insulated by today’s standards, and in a house where attic temperatures hit 150°F in summer, that deficiency shows up quickly. We assess what is already up there, remove or top over degraded material, air-seal the bypasses that let conditioned air escape, and install insulation matched to your home’s framing and ventilation. Older tract homes in Van Nuys often have recessed can lights, bathroom fans, and plumbing penetrations that were never sealed, and those small gaps collectively act like an open window.

Spray Foam Insulation in Van Nuys
Spray foam works differently than blown-in fiberglass or cellulose, and in certain Van Nuys homes it is the best answer. Open-cell foam excels at air sealing irregular attic spaces and sound control in multi-unit buildings, while closed-cell adds structural rigidity and a moisture barrier, which matters in older wood-frame buildings. For attic roof decks and knee walls where traditional insulation underperforms, spray foam stops heat before it enters the living space. Spray Foam Insulation in Van Nuys

Blown In Insulation in Van Nuys
Blown in insulation is the most practical retrofit for most Van Nuys homes because it fills irregular attic cavities completely, compacts less over time than batts, and can be installed over existing material without a full tear-out. In a city where summer attic temperatures exceed 150°F and winter nights can drop to freezing, the difference between thin, settled insulation and a proper blown-in layer is the difference between an HVAC system that runs constantly and one that cycles normally. We install blown in fiberglass and cellulose from manufacturers like Owens Corning and GreenFiber, choosing the material based on your attic’s depth, ventilation, and whether you want recycled content. Visit our Blown In Insulation hub for background on how the service works.
Cellulose Insulation
Signs you need it
If your attic currently has thin fiberglass batts with visible gaps, dust accumulation, or sections compressed to under six inches, cellulose blown in over the top can restore performance without removing the old material.
What it costs in Van Nuys
Blown-in cellulose in Van Nuys typically runs $1.20 to $2.30 per square foot installed, depending on attic accessibility and the R-value target.
How we do it
We air-seal the attic floor penetrations first, then use commercial blowing equipment to distribute GreenFiber cellulose to a consistent, code-meeting depth across the entire attic floor.
Blown In Attic Insulation
Signs you need it
You need blown in attic insulation if upstairs rooms run 10 to 15 degrees hotter than the rest of the house in summer, or if your attic has only a few inches of old material left.
What it costs in Van Nuys
Blown in attic insulation in Van Nuys generally falls between $1.50 and $3.50 per square foot, with total attic projects commonly landing in the $1,800 to $4,200 range for typical 1,200 to 1,800 square foot homes.
How we do it
We assess the existing attic depth, air-seal bypasses, install baffles where soffit vents are present, then blow Owens Corning fiberglass or GreenFiber cellulose to your target R-value.
Blown In Cellulose Insulation
Signs you need it
Homes with older, settled insulation that measures under R-30 in the attic are prime candidates for blown in cellulose, especially when the homeowner wants a higher recycled-content material.
What it costs in Van Nuys
Blown in cellulose for a Van Nuys attic runs $1.20 to $2.30 per square foot, with GreenFiber products available for customers who prioritize eco-conscious insulation options.
How we do it
Our crew removes any moisture-damaged material, seals air leaks, and then blows cellulose to a uniform depth that meets or exceeds the R-value required for Southern California’s climate zone.
Blown In Fiberglass Insulation
Signs you need it
If you prefer a non-cellulose option with strong thermal performance and no settling concerns when installed properly, blown in fiberglass is a good match for Van Nuys attics.
What it costs in Van Nuys
Blown in fiberglass in Van Nuys typically costs $0.90 to $1.80 per square foot installed, depending on roof pitch and access clearance.
How we do it
We blow Owens Corning or Knauf loose-fill fiberglass using calibrated equipment, achieving consistent coverage without the gaps and compression that hand-placed batts leave behind.
Loose Fill Insulation
Signs you need it
Loose fill insulation is the answer when an attic has odd joist spacing, tight corners, or a mix of old material that makes batt installation impractical or ineffective.
What it costs in Van Nuys
Loose fill insulation in Van Nuys runs $1.00 to $2.80 per square foot, with the final figure depending on whether fiberglass or cellulose is used and how much old material must be removed first.
How we do it
We prep the attic by sealing bypasses and clearing vent paths, then use a blowing machine to fill every cavity evenly, including around ductwork and recessed fixtures.
What Blown In Insulation Costs in Van Nuys
| Item | Typical range in Van Nuys |
|---|---|
| Blown in fiberglass (attic) | $0.90 – $1.80 per sq ft |
| Blown in cellulose (attic) | $1.20 – $2.30 per sq ft |
| Full attic retrofit (1,200 – 1,800 sq ft home) | $1,800 – $4,200 |
Is blown in insulation worth it in Van Nuys?
Yes. Given that Van Nuys attics hit 150°F in summer, a proper R-38 to R-49 blown-in layer typically cuts attic heat transfer enough to reduce cooling bills noticeably, often paying for itself within a few years.
Can you blow insulation over old batts in my Van Nuys attic?
In most cases, yes. We blow loose-fill material directly over existing batts as long as they are dry and mold-free. Damaged or rodent-soiled material gets removed first. Call (877) 680-3557 for an assessment.
