Why North Tustin Insulation Is North Hills’s Preferred Attic Insulation Company
North Hills homeowners don’t need a general contractor who happens to own a blower. They need someone who knows that a 1960 stucco ranch on a Woodley Avenue cul-de-sac behaves completely differently than a newer Van Nuys condo. We carry eight insulation brands: Owens Corning, CertainTeed, Johns Manville, Knauf, Rockwool, GreenFiber, Icynene, and Demilec. That means when we walk your attic, we’re matching the material to the house, not pushing whatever’s sitting in the truck.
Our team focuses on insulation and nothing else. No roofing side jobs. No HVAC upsells. Every estimate Allen Decker sends out reflects that singular focus. We know the building patterns in 91343 and 91393: original 2×4 walls with no insulation, unlined attics, single-pane aluminum windows. The fix isn’t always glamorous, but it’s always specific.
Response time to North Hills from our North Tustin base is same-day or next-day for estimates. We stock common retrofit materials locally, so a blow-in job off Sepulveda or Nordhoff doesn’t sit waiting on a supply house delivery.
Attic Insulation Removal in North Hills
Attic Insulation Removal in North Hills is a job we handle weekly, usually because the original fiberglass batts from a 1958 tract home have compressed to a fraction of their rated R-value, or because rodents got into the attic and left contaminated material behind. In 91343 specifically, the extreme summer heat accelerates that compression. When insulation sits at 120°F-plus for months, it breaks down faster than it would in a coastal climate. We remove the old material, bag it, and prep the attic for fresh insulation, usually with a full sanitation pass before new material goes in.
When Removal Is the Only Option
If your North Hills attic has original insulation from the Eisenhower administration, adding more on top doesn’t fix the problem. Compressed fiberglass loses its loft, and the R-value is gone. Same story with rodent damage: droppings and urine in the insulation create a health issue that no top-up solves.
We also remove insulation after roof leaks in North Hills. A small leak that sat unnoticed in a low-pitch attic creates mold where you can’t see it. Pull it out, dry the space, then re-insulate. That’s the honest sequence.
Cost of Removal in North Hills
Removal alone in a standard North Hills ranch attic runs $800 – $1,600. If we’re doing removal plus new blown-in or batt insulation, expect $2,500 – $5,000 total, with the higher end covering larger attics, heavy contamination, or difficult access through a small interior hatch. Call (877) 265-5712 and Allen will walk through what your attic actually needs.
Insulation Contractors in North Hills
Insulation Contractors in North Hills fall into two camps: generalists who’ll take the job if it fits their schedule, and specialists who understand what a 1962 stucco ranch with a converted garage actually needs. We’re the second type. North Hills has one of the highest concentrations of post-WWII tract housing in the Valley, and those homes were designed for a different climate assumption. Nobody was cooling a 1,500 sq ft house to 72°F in 1959. Now everyone is, and the original uninsulated attics can’t keep up.
Matching Material to a 91343 Home
A single-story North Hills ranch with a low-pitch attic and accessible joists is a clean candidate for blown-in GreenFiber cellulose to R-49. A converted garage with vaulted framing wants closed-cell spray foam, which is why we carry both Icynene and Demilec. A homeowner who wants rock-solid fire resistance and sound control gets Rockwool mineral wool. The material follows the house.
Licensed, Focused, Local to the Valley
We’re an insulation-exclusive contractor serving North Hills and the surrounding Valley. Every person on our crew does insulation daily, which is why we can spot a ventilation issue or thermal bridge in minutes that a generalist would walk past. Licensed and insured, with brand-specific training on every product we install.
Trusted Brands We Service in North Hills
North Hills homeowners ask us constantly which brand is “best.” The honest answer: the one that fits your attic, your budget, and your priorities. We carry CertainTeed and Owens Corning fiberglass for straightforward batt retrofits, GreenFiber recycled cellulose for blown-in jobs, and Icynene and Demilec for spray foam applications where air sealing matters most. That’s real material choice. We stock common products for North Hills jobs and can have specialty material on site within 48 hours, which means less waiting between estimate and install. No brand evangelism. Just the right product for the house on Woodley, Chase, or Sepulveda.
Common Attic Insulation Problems We See in North Hills Homes
- Unpermitted patio enclosures and converted garages. North Hills tract homes from the 50s and 60s frequently have these additions put in without permits. They create thermal bridges that bypass attic insulation entirely. A homeowner cools the main house fine but the “bonus room” stays 15°F hotter, and the attic gets blamed.
- Original insulation turned to dust. Fiberglass batts installed in 1960 have had 60-plus summers of 100°F heat cooking them. The loft is gone, the R-value is a fraction of what the label promised, and the homeowner is paying to cool the attic instead of the living room.
- Low-pitch attics with no ventilation. North Hills ranches were built with shallow roof pitches and minimal eave vents. Heat and moisture trap up there, degrade insulation faster, and shorten roof life. A retrofit that adds baffles and improves airflow pays off immediately in comfort and longevity.
- Attic hatch leaks. A surprising number of North Hills homes still have the original unsealed attic hatch. It’s a two-foot-square hole in your thermal envelope. We seal and insulate the hatch on nearly every attic job we do in 91343.

FAQs About Attic Insulation in North Hills
North Hills gets extreme summer heat, routinely above 100°F, combined with a large day-night temperature swing. That thermal cycling breaks down fiberglass and cellulose faster than in coastal or more moderate LA neighborhoods. The shallow attic pitch common to 1950s-60s tract homes also traps heat and moisture, accelerating degradation. If your insulation is original to a pre-1970 home, it’s almost certainly underperforming. Call (877) 265-5712 for an attic inspection.
Yes. Unpermitted patio enclosures and converted garages are among the most common spaces we insulate in North Hills. These rooms have thermal bridging at the framing, poor or no vapor protection, and no original insulation. We can insulate the enclosure itself, treat the attic above, or both, depending on how the space is built and used. We work on the building as it exists. That’s the practical answer.
We carry CertainTeed fiberglass, GreenFiber recycled cellulose, Rockwool mineral wool, Icynene spray foam, and Demilec spray foam, among eight total brands. For most North Hills ranch attics, GreenFiber blown-in cellulose to R-49 is the value sweet spot. For converted garages or spaces with air-sealing demands, Icynene or Demilec closed-cell foam does the job. The house decides the material, not the other way around.
Removal in North Hills typically involves vacuuming out old, compressed fiberglass or cellulose, sanitizing the attic space, and addressing any rodent entry points or roof leaks before new insulation goes in. The job costs $800 – $1,600 for removal alone in a standard 91343 attic. We bag and haul everything, leaving the attic clean and ready for fresh material.
R-49 is the standard we recommend for attics in North Hills, matching current energy code for the San Fernando Valley climate zone. That means about 15-16 inches of blown-in cellulose or the equivalent in other materials. Some North Hills homeowners choose R-60 for maximum summer heat resistance, especially if they run AC heavily. The right number depends on your attic depth, ventilation, and HVAC setup. Call (877) 265-5712 for a specific recommendation.
