Insulation Company in North Hollywood, CA
Blown in insulation is the fastest way to fix a hot, dusty, or drafty North Hollywood home, especially the 1920s – 1950s bungalows and 1960s – 70s apartment flats that dominate the neighborhoods around Lankershim, Victory, and the NoHo Arts District. We’re Porch Light Insulation, and insulation is the only trade we work in. Most of the homes we service in the 91601, 91602, 91605, and 91606 ZIP codes were built when builders assumed the San Fernando Valley climate made insulation optional. It wasn’t, and it isn’t. If your rooms bake by 3pm in August or you hear every truck on Burbank Boulevard, call (877) 521-4987 for a free estimate.
Why North Hollywood Homes Are Different
North Hollywood sits inland, not coastal. Summer highs routinely cross 100°F while winter nights dip into the 40s. That swing turns uninsulated attics into solar ovens for five or six months a year. The housing stock makes it worse. The 1920s – 1940s bungalows and duplexes around the Arts District are largely single-wall or thin-wall wood frame, built before anyone thought about R-value. The 1960s – 70s stucco garden apartments and four-plexes along the Victory/Vineland and Lankershim corridors often have flat roofs, sealed soffits, and no attic access at all. We find 1970s apartments with zero attic insulation and ceilings that literally radiate heat by mid-afternoon.
Noise is the other constant. The Red Line subway corridor, Burbank Boulevard, Chandler, and Lankershim all carry heavy truck and rail traffic. Attics and crawlspaces in this area act like echo chambers, pulling in diesel soot and brake dust along with the sound. A large share of our North Hollywood jobs are as much about sealing out freeway and rail noise as they are about lowering energy bills. Ember-resistant vent screening also matters here, given the dry brush-fire season.
Our Main North Hollywood Services
North Hollywood homeowners call on us most for two services: attic insulation and spray foam. Here’s what each one looks like in this city.
Attic Insulation in North Hollywood
Most North Hollywood attics are hot, under-insulated, and tricky to access. Bungalows have low-slope roofs with minimal soffit venting. Garden apartments often have flat roofs with no walkable decking. We air-seal first, then install the right material for the roof type and budget. Read more on our dedicated Attic Insulation in North Hollywood page.
Spray Foam Insulation in North Hollywood
For flat-roof apartments and converted garages, spray foam is often the only practical option. Closed-cell foam handles the Valley heat and adds structural strength to older roof decks. Open-cell foam delivers air sealing and sound dampening for homeowners near the Red Line or busy truck routes. See the full breakdown at Spray Foam Insulation in North Hollywood.

Blown In Insulation in North Hollywood
Blown in insulation is our most-requested service in North Hollywood because it solves two problems at once: it fills the gaps and voids in older attics that batt insulation can’t reach, and it can be installed quickly even in low-clearance bungalow attics and flat-roof apartments where no walkable decking exists. For 1920s single-wall homes around the Arts District and 1970s garden apartments along Victory and Vineland, blown in material, whether cellulose or fiberglass, is often the only retrofit that works without tearing open walls or ceilings. We match the material to your home, not to our inventory, using products from CertainTeed, GreenFiber, and other manufacturers we’re authorized to install. Learn more about the full method on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic has old, settled insulation or bare spots, and your upstairs rooms feel hotter than the rest of the house.
What it costs in North Hollywood
Cellulose blown into an attic in North Hollywood typically runs $1.20 – $2.50 per square foot installed, depending on depth and access.
How we do it
We air-seal the attic floor, then use a calibrated blower to install loose-fill cellulose to the target R-value, raking it level around the entire deck.
Blown In Attic Insulation
Signs you need it
Your AC runs nonstop from June through October and the ceiling below the attic feels warm to the touch by late afternoon.
What it costs in North Hollywood
Blown in attic insulation in North Hollywood generally costs $1.20 – $2.80 per square foot, with flat-roof and low-access attics landing at the higher end.
How we do it
We locate existing venting and bypasses, seal around plumbing and electrical penetrations, then blow insulation to code depth or higher.
What Blown In Insulation Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Blown in attic insulation | $1.20 – $2.80 per sq ft |
| Cellulose insulation | $1.20 – $2.50 per sq ft |
| Air sealing (attic floor prep) | $400 – $1,200 per job |
How long does blown in insulation take in North Hollywood?
Most blown in attic jobs finish in one day, four to six hours for a standard bungalow. Flat-roof apartments with limited access can take longer. Call (877) 521-4987 for a schedule estimate.
Is blown in insulation better than batts for older North Hollywood homes?
Usually, yes. Blown in material fills irregular joist bays and gaps in 1920s – 1970s framing far better than cut-and-fit batts. It also installs faster in low-clearance attics. We’ll tell you if batts make more sense for your roof type.

We install CertainTeed and GreenFiber blown in products, plus Icynene and Demilec spray foam lines for North Hollywood attics and flat roofs. Product availability is solid across the Valley, which means most jobs can be scheduled within a week. See the full list at our brands page.

FAQs About Insulation Company in North Hollywood
Most estimates are scheduled within one to two business days, and many blown in attic jobs can be completed the same week. Emergency air sealing for ember or soot intrusion can often be prioritized. Call (877) 521-4987 to check current availability.
Most insulation retrofits do not require a permit, but some flat-roof or structural spray foam applications may need a plan check through LA City. We’ll tell you exactly what applies to your building type, including any HOA or landlord requirements for apartment buildings.
