Fast, Reliable Attic Insulation Across Van Nuys
Attic insulation in Van Nuys runs $1,800 – $4,200 for a typical 1,200 – 1,600 sq ft single-story tract home, depending on whether we’re topping up existing material or doing a full removal and reinsulation. Most jobs are completed in one day. The real issue in Van Nuys isn’t just missing insulation, it’s fifty to seventy years of degradation, settling, and heat cycling that’s left attics performing at a fraction of their original spec. If your home was built between 1940 and 1970 anywhere from Van Nuys Blvd to Sepulveda, you’re likely working against original or badly thinned material.

Why Laguna Hills Insulation Is Van Nuys’s Preferred Attic Insulation Company
We work across Van Nuys every week, from the tree-lined streets of Valley Glen’s edge down to the apartment-dense blocks near Victory and Woodman. Garrett Lund, our lead, has walked hundreds of these 1940s to 1960s attics and knows exactly what hides under the decking: degraded rock wool, settled cellulose, dead vents, and wiring that hasn’t been touched since the Eisenhower administration. That familiarity means we don’t quote generic jobs. We quote your house.
Our Van Nuys customers consistently mention two things: we show up on schedule, and we explain the material options before we ever pick up a hose or a batt. No single-line pressure. We carry Owens Corning, Johns Manville, Knauf, and Rockwool insulation among our stock, and we’ll tell you when blown-in fiberglass does the job versus when mineral wool or a radiant barrier makes more sense in this specific valley heat. Call (866) 393-6041 and we’ll usually have someone out to Van Nuys within a day or two.
Radiant Barrier in Van Nuys
Radiant Barrier in Van Nuys is often the single most effective add-on for roofs that take direct afternoon sun, because the barrier reflects radiant heat before it ever reaches your insulation. In a 1950s tract house with a low-pitch roof, the attic can easily hit 130 – 140°F by 2 p.m. in July. That heat radiates down through whatever R-value you have, and if your insulation is thin, the ceiling below becomes a radiator. A radiant barrier stapled to the roof deck cuts that transfer by up to 30 – 40°F, which means your AC doesn’t run as long and your upstairs rooms don’t feel like ovens by dinner.
Typical radiant barrier installation in Van Nuys runs $800 – $1,600 for a standard single-story home, depending on attic size and roof complexity. If you’re already doing blown-in insulation, adding the barrier at the same time is the smart play.
When the Roof Deck Needs It
Low-pitch roofs with dark shingles absorb heat all day and release it slowly into the attic after sundown. Homes around Van Nuys Blvd and Sherman Way with no shade trees see the worst of it. The barrier goes under the decking, against the rafters, and reflects that load back toward the roof surface.
Material Nuance
Not every attic needs a radiant barrier. If you have good ventilation and we’re blowing insulation to R-38 or higher, the barrier might be overkill. We’ll tell you that. It’s part of the material-agnostic approach, and it’s also why we mention it honestly rather than adding it to every quote.
Attic Cleaning Services in Van Nuys
Attic cleaning in Van Nuys matters more here than in newer developments because most of these attics have accumulated decades of dust, rodent droppings, and degraded fiberglass dust that’s actually harmful to breathe and degrades new insulation’s performance. If your attic needs Reflectix repair in Van Nuys, we can assess whether it’s the right solution alongside cleaning. Before we blow in new material, the old stuff has to come out. You can’t just cover contamination and call it done.
Full attic cleaning and old insulation removal in Van Nuys runs $1,200 – $2,800 depending on attic size, access difficulty, and what’s actually up there. Some attics are clean enough for a simple top-up, but where there’s evidence of rats or mice, it’s a full removal job, and it should be.
What Contaminated Attics Look Like
In the older neighborhoods near Sepulveda and Oxnard, we regularly pull out nests, droppings, and insulation that’s been pressed down to a fraction of its original loft. Rodent activity compresses fiberglass and destroys its R-value. Blowing over it doesn’t restore anything.
Deep Cleaning Before Reinsulation
We vacuum out the old material, sanitize the deck, and inspect for gaps or holes before any new insulation goes in. The cleaning itself is often what makes the R-value upgrade worth doing at all.

Trusted Brands We Service in Van Nuys
We’re not tied to one manufacturer’s line, which means we can match the right product to your specific Van Nuys attic rather than the other way around. We work with Owens Corning fiberglass for most blown-in and batt applications, Knauf for cost-effective bulk fills, and Rockwool for attic spaces where fire resistance or moisture resistance matters, like older apartments with shared walls. Because we stock materials for Van Nuys customers as part of our normal route coverage, we’re able to schedule most material orders the same week we inspect. No week-long waits for specialty product. The full Attic Insulation team handles everything from removal and air sealing to final R-value verification.
Common Attic Insulation Problems We See in Van Nuys Homes
- Settled rock wool or cellulose at R-7 or below. Original insulation in 1940s and 1950s tract homes along Vanowen and Victory has often compacted by 50% or more, leaving the ceiling nearly unprotected against summer heat gain.
- Unvented or poorly vented attics trapping 130°F+ air. Many Van Nuys homes have no ridge vent or soffit intake, so heat just sits up there and cooks the insulation, degrading it faster and making radiant barriers underperform.
- Knee-wall attics over garages that have never been insulated. The garage in a 1952 tract home off Sepulveda typically has a small attic access door that no one has opened in sixty years. That space is often completely uninsulated, which drags down the temperature of the room above it.
- Knob-and-tube or early romex wiring in the attic getting buried by new insulation. Blowing insulation directly over old wiring can compress connections and create a fire hazard. In Van Nuys specifically, we see this in homes that still have their original electrical panels, and we’ll flag it before any material goes down.
Pricing for Attic Insulation in Van Nuys, CA
A straight blown-in insulation top-up for a 1,200 sq ft Van Nuys attic typically runs $1,800 – $2,600. Full removal of old contaminated material, air sealing, and reinsulation to R-38 is closer to $3,200 – $4,500. Radiant barrier add-on lands in the $800 – $1,600 range we mentioned. Attic cleaning alone is $1,200 – $2,800. What moves the needle: access difficulty, existing wiring conditions, attic height, and whether you’re in a single-story stucco home versus a multi-unit building with shared attic space.

FAQs About Attic Insulation in Van Nuys
Yes, in many cases we can blow new fiberglass directly over existing rock wool, provided the old material is dry, uncontaminated, and not covering wiring or junction boxes. We assess the condition of the existing insulation first. If it’s compressed to R-7 or below and degraded, a full removal gives you much better performance and lets us air-seal the top plates. Call (866) 393-6041 and we’ll tell you which path fits your house.
We recommend R-38 to R-49 for most Van Nuys attics, because the primary challenge is heat gain rather than heat loss. The Department of Energy’s zone, plus our own experience with 100°F+ summer days, confirms that R-38 is the practical floor for blown-in fiberglass or cellulose, with R-49 preferred for homes with low-pitch roofs and no shade. Radiant barrier complements that R-value but doesn’t replace it.
We can insulate around it, but we won’t blow material directly over live knob-and-tube connections or any junction boxes that haven’t been properly enclosed. In Van Nuys, where early romex and some remaining knob-and-tube are common in pre-1960 homes, we’ll ask you to have an electrician inspect and address any exposed or damaged wiring before we schedule the insulation. It’s a safety issue, not a sales one. Call (866) 393-6041 and we’ll walk you through the sequence.
A radiant barrier reflects heat before it enters the attic, while insulation slows the transfer of heat already in the space. In Van Nuys’s intense afternoon sun, they do different jobs. If your attic is already well-insulated but still hitting 130°F+, the barrier is often the better next step than adding more fiberglass. If your attic is at R-7, insulation alone won’t solve your problem, and we’d recommend doing both in most cases.
Yes, and it’s one of the most common upgrades we do in older Van Nuys tract homes. We can blow insulation into the knee-wall attic space over the garage, or insulate the knee wall itself depending on how the space is configured. These areas are frequently overlooked because they’re hard to access, and leaving them uninsulated means the room above the garage absorbs heat all day. Call (866) 393-6041 for a free estimate on that specific area.
