Fast, Reliable Attic Insulation Across Van Nuys
Attic insulation in Van Nuys is a different job than it is in Santa Monica or West LA. Our summers push attic temperatures past 140°F, and the 1920s-to-1970s housing stock scattered through 91401, 91405, and 91406 was never built to handle that heat load. Porch Light Insulation works in Van Nuys every week, and we’ve opened enough attics along Van Nuys Blvd and the surrounding residential grid to know exactly what fails here first. If you’re tired of upstairs rooms that hit the high 80s by 3 p.m., or you’ve noticed your AC running nonstop from June through October, the problem is probably above your ceiling. Call us at (877) 521-4987 and we’ll put an insulation specialist in your attic, not a general contractor.
Why Porch Light Insulation Is Van Nuys’s Preferred Attic Insulation Company
Insulation is the only trade we practice. That matters in Van Nuys because the older stucco-over-wood-frame ranches here hide problems a roofer or an HVAC tech won’t catch: collapsed 1950s rock-wool batts, rodent-nested kraft-faced fiberglass, top plates that were never air-sealed to begin with. Our estimators and installers spend every working day thinking about thermal boundaries, venting, and R-value, so when we walk a Van Nuys attic, we see what’s actually driving your cooling bills.
We carry products from eight manufacturers, including Owens Corning, Johns Manville, and GreenFiber, which means we don’t steer every Van Nuys homeowner toward the same material. A 1948 ranch off Van Nuys Blvd needs something different from a 1970s tract house near Valley Glen. Our team is led by Gil Tanner, and he’s built the company around a simple rule: match the material to the house, not to whatever’s left in the warehouse. Response time to Van Nuys ZIP codes 91401, 91405, 91406, and 91411 is typically next-day for estimates and same-week for installs.
Radiant Barrier in Van Nuys
Radiant Barrier in Van Nuys is the single highest-impact upgrade you can make when your attic is already hitting 140°F to 160°F in July. A radiant barrier is a reflective sheet stapled to the underside of your roof rafters that blocks radiant heat transfer from the roof deck into the attic space. In a Valley basin climate like ours, that heat transfer is the dominant load. Traditional insulation slows conductive heat, but a radiant barrier stops the solar energy before it ever reaches your insulation, your ductwork, or your living space.
What It Involves
We mount a foil-faced barrier under the rafters, making sure it’s not touching the roof deck, because the air gap is what does the work. The barrier reflects a large share of the roof’s radiated heat back out through the shingles. On a low-slope or hip roof over a rear addition, where Van Nuys attics trap heat the worst, this installation pays back faster than adding more R-value alone.
What Van Nuys Homeowners Should Expect to Spend
A radiant barrier install in Van Nuys typically runs from $1,200 to $2,800 depending on roof complexity and attic access. When combined with air-sealing and a blown-in insulation top-up on a 1,200-square-foot ranch, plan for $3,500 to $6,000. We pair radiant barrier with soffit baffles so your attic still breathes while the barrier reflects heat.
Attic Cleaning Services in Van Nuys
Attic Cleaning Services in Van Nuys are often the first step before any new insulation goes in, and we recommend them more often here than in cooler parts of Los Angeles. Decades of 100°F-plus summers dry out old kraft-faced batts and 1950s rock-wool until they crumble and compact. Rodents, drawn to the warm, quiet space under a Valley roof, tunnel through whatever’s left. What you get is a dusty, odorous layer of degraded material sitting on top of your ceiling drywall, doing nothing for your R-value.
What We Remove
We vacuum out collapsed rock-wool, shredded fiberglass, rat droppings, nesting debris, and years of fine Valley dust. Then we sanitize the attic deck and inspect for wiring damage. Only after the space is clean do we evaluate air-sealing and insulation. Putting new insulation over old rodent-nested material just preserves the problem underneath.
Typical Cost in Van Nuys
Attic cleaning for a typical Van Nuys ranch, around 1,000 to 1,400 square feet, runs $900 to $1,800. Larger homes or attics with heavy rodent contamination will run higher. We’ll give you a firm number after an attic walk-through. Call (877) 521-4987 and we’ll schedule it.

Trusted Brands We Service in Van Nuys
We install and maintain insulation from Owens Corning, GreenFiber, and Demilec, among others. For Van Nuys retrofit work, we lean on GreenFiber’s blown-in cellulose for its coverage and air-sealing properties, and Owens Corning fiberglass where homeowners want a batt solution. Demilec’s open-cell spray foam works well in the tight, complicated attic cavities we find over rear additions and enclosed porch roofs. We stock the materials our Van Nuys customers need in our local supply chain, so turnaround doesn’t stall waiting on a distributor. Our Attic Insulation team brings the right product for your house, not the product we’re trying to move that month.
Common Attic Insulation Problems We See in Van Nuys Homes
- Collapsed 1950s rock-wool batts: In the stucco ranches off Van Nuys Blvd and throughout 91401, we regularly find original rock-wool that has compacted to a fraction of its original thickness. After sixty-plus years of 140°F-plus attic heat, it’s doing almost nothing.
- Rodent-tunneled fiberglass: Pre-war bungalows and 1960s tracts are prime nesting territory. Rats and mice shred kraft-faced batts, leaving gaps you can see straight through to the ceiling below, along with odor and contamination that carries into the living space.
- Bare joists over rear additions: The flat and low-slope roofs that builders tacked onto Van Nuys homes in the 1960s and 1970s frequently have no insulation at all above the ceiling. On a 104°F afternoon, the drywall reads near-ambient air temperature.
- Unsealed top plates and can lights: Even where older insulation exists, the gaps around wall top plates and recessed light housings let conditioned air pour into the attic and pull 150°F air into the house. Air-sealing fixes this before any R-value gets added.

FAQs About Attic Insulation in Van Nuys
Start with an attic inspection that tells you what’s actually up there. Many of these 1940s and 1950s builds have original rock-wool that’s collapsed off years of Valley heat, so we check what exists, whether it’s rodent-nested, and whether your top plates and can lights are sealed. That determines whether we clean, air-seal, add a radiant barrier, or blow in new insulation. Call (877) 521-4987 and we’ll schedule a free walk-through in Van Nuys, usually within a day or two.
Yes, and it’s one of the highest-payback upgrades for this specific climate. Radiant barrier reflects heat from the roof deck before it can radiate into your attic and soak through your ceiling. In Van Nuys’s semi-arid Valley summers, that radiant load is the primary driver of attic heat, so a barrier plus air-sealing often outperforms adding R-value alone. Homeowners regularly tell us their west-facing rooms stop climbing past 80°F in the afternoon after we install one.
Decades of 140°F-plus attic temperatures bake kraft-faced batts and rock-wool until the fibers break down and the material compacts. Rodents accelerate the damage by nesting and tunneling. Once insulation crumbles or compacts to a fraction of its original depth, it no longer holds the R-value it was installed with. In Van Nuys, the fix is removal, air-sealing, and new blown-in material. Call (877) 521-4987 for a free estimate.
Stucco walls make exterior rigid-foam retrofits difficult and expensive on most Van Nuys homes, which is exactly why attic work carries the load here. The attic is the one place in these older stucco ranches where we can add significant R-value without tearing open walls. Between blown-in insulation, air-sealing, and a radiant barrier, we can cut the attic-driven heat gain that makes your AC run all afternoon. In many cases, that’s more cost-effective than touching the walls at all.
We choose the brand based on the attic, not the other way around. For most Van Nuys retrofit work, we use GreenFiber blown-in cellulose for its coverage and air-sealing characteristics. Owens Corning batts work well for accessible attics where mechanical systems and storage need to stay functional. Demilec open-cell spray foam handles the weird geometries over rear additions. We’re authorized installers for eight manufacturers, so the recommendation is about your house. Call (877) 521-4987 and we’ll walk you through what fits best.
