Fast, Reliable Attic Insulation Across North Hollywood
Attic insulation in North Hollywood means solving one specific problem: flat, low-slope attic spaces that turn into ovens by noon and radiate that heat into your living rooms for hours afterward. Brea Insulation knows these San Fernando Valley homes because we work on them every week. Our crews reach most North Hollywood ZIP codes the same day or next morning, and we stock the materials these mid-century houses need. Call (866) 858-4033 for a free estimate.
Why Brea Insulation Is North Hollywood’s Preferred Attic Insulation Company
We’re a dedicated insulation contractor. Insulation is the only thing we do, which means we don’t split attention across roofing, HVAC, or drywall jobs the way a generalist does. That focus matters in North Hollywood, where post-war stucco bungalows and small duplexes need a specific retrofit approach, not a one-size-fits-all install.
Homeowners across North Hollywood have called us for everything from blown-in attic top-ups near Valley Glen to full radiant barrier work off Burbank Boulevard. The recurring job is a 1940s – 1970s house with thin original insulation, a flat attic, and an A/C unit running hard from May through October. We diagnose the actual problem first, then match the material to the house rather than pushing whatever is cheapest to stock.
Phil Darnell, who runs Brea Insulation, has built the company around one idea: carry the full material bench so the recommendation is driven by the home’s needs. We work with Owens Corning, Icynene, Demilec, GreenFiber, and others, so a North Hollywood homeowner who wants recycled cellulose gets GreenFiber, and one who wants air-sealing performance gets open-cell spray foam. Same crew, same project, right product.
Radiant Barrier in North Hollywood
Radiant Barrier in North Hollywood is the highest-impact upgrade you can make to a flat or low-slope post-war attic, because it directly blocks the radiant heat that bakes these spaces past 120°F by midday while fiberglass or cellulose alone only slows that heat down. We staple a reflective foil barrier across the underside of the rafters so solar gain reflects back out instead of radiating into the attic air and then through your ceiling. In the San Fernando Valley, where summer highs routinely push past 95°F and there’s almost no marine cooling, a radiant barrier routinely cuts attic temperatures by 20 – 30°F and drops A/C cycling the same week. A radiant barrier install in North Hollywood typically runs $900 – $1,800 depending on attic square footage and rafter access.
Foil Barrier With Air Sealing
We pair the radiant barrier with air sealing at the drywall plane. In NoHo’s 1950s bungalows, recessed lights, loose attic hatches, and plumbing penetrations let superheated attic air pour into the living space below. Sealing those first means the barrier and insulation actually perform as designed.
Flat Roof Attic Access
Many North Hollywood houses have truly flat or very low-slope roofs with cramped attic access. We send a small crew that can work in those conditions. The barrier goes in as close to the roof deck as possible, leaving the insulation plane below it intact.
Attic Cleaning Services in North Hollywood
Attic Cleaning Services in North Hollywood are often the necessary first step before adding insulation, because decades of settled dust, old rodent activity, and broken-down original fiberglass can hide air leaks and contaminate the space we’re about to seal. Many of the 1940s – 1970s stucco bungalows we work on have never had their attics cleaned. Old insulation has settled into the joist bays, sometimes to an R-value of R-11 or less, and there’s often debris from old remodels. We remove the old material, vacuum the deck, and inspect for the failed can-light housings and drywall cracks that have been leaking Valley heat into the house for years. Attic cleaning in North Hollywood typically runs $500 – $1,200 depending on attic size, access, and how much material has to be removed.
Pre-1978 Lead Safe Containment
A large share of North Hollywood’s housing stock is pre-1978 plaster and drywall, which means attic penetrations and debris removal done without lead-safe work practices can contaminate the living space below. We run lead-safe containment on these jobs as standard: negative pressure, sealed attic hatches, and HEPA vacuuming at the end. It’s not an add-on; it’s the only way we do pre-1978 work.
Debris Removal Before Blown-In
If you’re planning blown-in cellulose or fiberglass, old debris has to come out first. Leaving it in place lets moisture and odors stay trapped under the new material. We clean the deck, then blow the new insulation to a consistent depth.

Trusted Brands We Service in North Hollywood
When we install GreenFiber cellulose in a North Hollywood attic, we’re using the material the customer asked for, not whatever the distributor had on sale. That’s the point of carrying an eight-brand bench. We stock and install Owens Corning fiberglass, Icynene and Demilec spray foam, GreenFiber recycled cellulose, and Rockwool mineral wool, among others. For NoHo’s flat, oven-hot attic spaces, the typical winners are GreenFiber blown-in for dense coverage or an Icynene open-cell foam for air-sealing performance. We keep local stock ready and can schedule most North Hollywood jobs within a week.
Common Attic Insulation Problems We See in North Hollywood Homes
- Oven-hot flat attics. The flat or low-slope attic spaces in 1940s – 1970s stucco bungalows bake to oven-like temperatures by midday, cooking thin original insulation until it settles and loses R-value. A radiant barrier plus high-R blown-in assembly is the fix, not more fiberglass batts alone.
- Settled original insulation. Many NoHo houses still have their original 2 – 3 inch batt insulation, now compressed to R-9 or R-11. We see this constantly in the flats east of the Red Line. The trap is assuming you just need a top-up when the real problem is air leaks around the settled material.
- Pre-1978 lead-safe reality. The older plaster and drywall stock here means attic penetrations done without lead-safe practices can contaminate the living space. We treat every pre-1978 attic as a lead-safe job until testing says otherwise.
- Air leaks at the drywall plane. Recessed lights, loose hatches, and unsealed plumbing chases let the Valley’s radiant heat pour straight past whatever insulation is up there. Insulation added without air sealing underperforms by 20 – 30% in these houses.

FAQs About Attic Insulation in North Hollywood
Why does my North Hollywood attic feel like an oven by midday even with some insulation?
Because the flat or low-slope roof deck on your post-war stucco house absorbs direct Valley sun all morning, and thin or settled insulation only slows heat transfer; it doesn’t block radiant gain. The roof deck itself hits 130 – 150°F, and that heat radiates down through whatever insulation is there. The fix is a radiant barrier directly under the roof deck plus air sealing, not just more fiberglass. Call (866) 858-4033 for an attic temperature assessment.
Does my pre-1978 North Hollywood house need lead-safe practices for attic insulation work?
Yes, most of the time. Pre-1978 plaster and drywall stock is common across the 91601, 91615, 91616, and 91618 ZIP codes, and any attic penetration, debris removal, or air sealing that disturbs that material can release lead dust into the living space. We run lead-safe containment on these jobs as standard, including negative pressure, sealed hatches, and HEPA vacuuming. It’s part of the quote, not an add-on.
What’s the difference between a radiant barrier and just blowing in more insulation for a NoHo attic?
Insulation slows conductive heat gain; a radiant barrier reflects radiant heat before it ever enters the attic air. In North Hollywood’s flat, low-slope attics, the roof deck is the primary heat source, so a barrier cuts attic temperatures by 20 – 30°F while blown-in insulation alone just makes the attic hold heat longer. We typically do both together. For a specific quote on your attic, call (866) 858-4033.
My attic has old settled insulation and debris, do I need attic cleaning before adding more?
If the old insulation is compressed, contaminated, or sitting below the joist tops, yes. Blowing new material over settled debris traps moisture and hides air leaks. We remove the old material, clean the deck, seal the drywall plane, then blow to a consistent depth. Attic cleaning in North Hollywood typically runs $500 – $1,200 before new insulation goes in.
Can you insulate the dense multifamily and rent-controlled apartments near the NoHo Arts District?
Yes. We work property managers and owners of the older multifamily and rent-controlled stock along the Red Line corridor and around the NoHo Arts District. Those buildings often have flat roof decks, thin attic space, and pre-1978 construction, which means lead-safe containment and careful air sealing. We quote per building. Call (866) 858-4033 and ask for Phil Darnell’s team.
