Insulation Company in North Hills, CA
Blown in insulation solves a problem North Hills homeowners know well: rooms that never quite cool down between June and October, and energy bills that climb every summer. The 1950s and 60s ranch homes that fill this part of the San Fernando Valley were built when attic insulation was treated as an afterthought, so we spend a lot of time in North Hills attics correcting forty-year-old decisions. If your west-facing bedrooms bake by 3 p.m., call (855) 341-7856 for an estimate on blown in insulation that actually holds temperature.
Why North Hills Homes Are Different
North Hills sits in the hotter, drier western San Fernando Valley, where summer highs routinely pass 100°F and the sun pounds south- and west-facing roofs from late morning to sunset. The housing stock tells a specific story: single-family ranch tract homes from the 1950s and 1960s with wood-frame construction, low-pitch attics, and original insulation that’s often settled, sparse, or missing entirely. We routinely find R-11 or R-13 batts from the Kennedy administration still in place when we climb up to air-seal and top off. Winters here are mild, so the insulation problem is overwhelmingly about cooling-season heat rejection rather than freeze protection.
Many North Hills attics sit above leaky ductwork in unconditioned space, which means your cooled air fights the attic heat before it ever reaches the bedrooms. The older homes along the residential streets west of Sepulveda and north of Roscoe frequently have single-pane windows and minimal original ceiling insulation, making the attic the single highest-impact insulation zone in the house. For North Hills homeowners, the fix usually starts at the top.
Our Main North Hills Services
Most North Hills homeowners call us about two things: an attic that’s radiating heat into the living space, or rooms that need air-sealing plus cavity fill in one pass. We handle both as an insulation-only specialist, which means the person who diagnoses your home is the same crew that installs the material.
Attic Insulation in North Hills
In North Hills, the attic is where comfort problems start. Homes built before California’s Title 24 energy standards exist often have a thin layer of original insulation, disturbed over decades by wiring, plumbing, and HVAC work. We air-seal the attic floor first, then blow or lay insulation to a depth that actually rejects the valley’s summer heat. For a full breakdown of what an attic job involves in North Hills, see Attic Insulation in North Hills.
Spray Foam Insulation in North Hills
Spray foam earns its keep in North Hills when a homeowner wants air-sealing and insulation in a single step, especially in low-pitch attics where batts and loose fill don’t fit cleanly. Closed-cell foam also adds structural rigidity, which matters on older wood-frame homes that have settled over six decades. For the complete picture on open-cell and closed-cell options in this climate, read Spray Foam Insulation in North Hills.

Blown In Insulation in North Hills
Blown in insulation in North Hills is the fastest way to bring a 1960s attic up to a level that rejects San Fernando Valley heat. Loose fill settles into every cavity and corner, covering the gaps that batts leave around framing, recessed lights, and plumbing penetrations. Because North Hills cooling seasons run long and hot, we dense-pack walls and top off attics with material that stops the thermal transfer from a roof that’s been baking in 100-degree heat since noon. If your home still has its original attic insulation, or rooms over the garage never equalize, blown in material is usually the most cost-effective correction. You can read more about how the method works on our Blown In Insulation resource page.

What North Hills Customers Say
"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Dustin Sullivan"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Marco Morales"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
