Insulation Company in North Hills, CA
North Hills homes lose conditioned air faster than most homeowners realize, and the fix usually comes down to blown in insulation installed correctly. Most of the housing stock here was built in the 1950s and 1960s, when R-7 to R-11 attic insulation was standard, and five decades of San Fernando Valley heat have compressed and degraded much of it. We’re Porch Light Insulation, and we specialize in matching the right material to each North Hills home, whether that means dense-packed cellulose in walls, loose-fill fiberglass across an attic floor, or spray foam where air sealing matters most. Call (877) 521-4987 for a free estimate.
Why North Hills Homes Are Different
North Hills sits in the middle of the San Fernando Valley, and in July and August, attic temperatures here routinely climb above 150°F. That heat cooks insulation from above while the home’s air conditioner fights from below, and the result is an energy bill that climbs every summer. The post-WWII tract homes that dominate the 91343 and 91393 ZIP codes were built for a different climate and a different energy cost. Original R-7 to R-11 attic insulation was considered adequate in 1955; today it’s roughly a third of what building codes require for new construction anywhere in Southern California. Add in aging ductwork running through those scorching attics, and you get a house that struggles to hold temperature even with the AC running full blast. We see the same pattern on block after block: old fiberglass batts that have collapsed to half their labeled R-value, or blown insulation that has settled into a thin, ineffective layer. The good news is that North Hills is also one of the highest-ROI retrofit markets in the Valley, because a properly insulated attic directly reduces the load on the HVAC equipment that’s already fighting 100°F+ days. When we work in North Hills, we’re not guessing; we know exactly what this climate does to insulation over time and what it takes to reverse it.
Our Main North Hills Services
Most North Hills homeowners call us for one of two things: a full attic insulation upgrade, or spray foam where air sealing is the real problem. Here’s what each involves in this neighborhood.
Attic Insulation in North Hills
In North Hills, attic insulation is the single most impactful retrofit for a 1950s or 1960s tract home. The original R-7 to R-11 material has usually settled, compressed, or been disturbed by decades of electrical work, and the attic is the primary path for heat gain in summer. We remove the old material where needed, air seal the attic floor, and install new insulation at current recommended levels for the Valley’s climate zone. Most jobs go from thin or patchy coverage to R-38 or better in a single day. For the full breakdown of materials, methods, and costs, see our dedicated page on Attic Insulation in North Hills.
Spray Foam Insulation in North Hills
Spray foam addresses what batts and loose-fill cannot on their own: air movement. North Hills homes with recessed lights, plumbing chases, and attic hatches that leak air into the attic will keep losing conditioned air no matter how much fiberglass sits on the floor. Closed-cell foam also adds structural rigidity and vapor control, which matters when winter nighttime temperatures swing sharply and condensation forms on attic framing. We install both open-cell options from Icynene and Demilec and closed-cell where the job calls for it. Read the details on our Spray Foam Insulation in North Hills page.

Blown In Insulation in North Hills
Blown In Insulation is the workhorse retrofit for North Hills attics, because it fills irregular cavities and covers existing batts in a way that rolls and batts cannot. In this neighborhood, where original attic insulation is often R-7 to R-11 and has been flattened by decades of Valley heat, blown in insulation restores the R-value ceiling fast and affordably. We can blow loose-fill fiberglass or cellulose over existing material to bring the attic up to current recommended levels, or start fresh when old insulation is too far gone.

Is blown in insulation worth it in North Hills?
It’s one of the highest-ROI retrofits for 1950s and 1960s North Hills tract homes. A full attic upgrade from R-11 to R-38 or better directly cuts summer heat gain and AC runtime. Homeowners typically notice the difference in comfort and bills within the first full summer.
Can you blow insulation over existing attic insulation in North Hills?
Yes, in most cases. If the existing insulation is dry, free of rodent contamination, and not too compressed, we can blow loose-fill fiberglass or cellulose right over it. We always inspect first and air seal before adding material. Call (877) 521-4987 for a free estimate.
