Insulation Company in North Hills, CA
Blown in insulation is the most common retrofit we install in North Hills, and the reason comes down to how these homes were built. Most houses here went up in the 1950s and 60s, when energy was cheap and builders treated insulation as an afterthought – if they used any at all. Today, with Valley summers pushing past 100°F, those thin, settled attics turn into heat sinks that drive cooling bills through the roof. We re-insulate them properly with material matched to the cavity, the access, and the home’s thermal boundary. Call us at (866) 271-1602 to talk through what’s in your attic now.
Why North Hills Homes Are Different
North Hills sits squarely in the San Fernando Valley’s inland heat zone. Summer days over 100°F are routine, and the diurnal swing – hot days, cool nights – puts real stress on any insulation product. The housing stock compounds the problem: single-story ranch and tract homes from the 1950s and 60s, mostly stucco, with low-pitch or flat roofs. Many were built with R-11 or less in the attic, and a lot of that original batt has been compressed flat under decades of heat. Wall cavities are often empty in these older frame homes.
The distinctive North Hills challenge is access. Low-clearance attics on these mid-century ranches make retrofitting tight, uncomfortable work. Plenty of contractors quote the job and never show up, because getting a hose into a cramped attic and reaching the far eaves is genuinely hard. That’s why we do blown in insulation here so often – it moves quickly through a 3-inch hose, fills irregular cavities, and reaches areas batts can’t. For homes off Roscoe and Sepulveda, the attics are frequently dormered or partially converted, which leaves odd thermal break lines that need careful air-sealing before insulation goes in.
Our Main North Hills Services
Two jobs dominate the call volume from North Hills homeowners: retrofitting attics in older ranch homes, and spray foam work where leaky building envelopes or odd additions need air-sealing. Each needs a different material approach.
Attic Insulation in North Hills
Most North Hills attic jobs are retrofits: we’re removing failed batts or topping off settled loose fill, then air-sealing before reinstalling. The low-pitch ranchers here mean we often work from confined angles, and the heat inside an uninsulated attic in August can hit 140°F. We address the radiant heat gain first, then the conductive loss. For homes with attic conversions or room additions done in the 80s and 90s, we rebuild the thermal boundary so the converted space stays conditioned. Full detail on this work lives on our Attic Insulation in North Hills page.
Spray Foam Insulation in North Hills
When a North Hills addition has open framing, a flat roof with no venting, or a crawlspace that’s pulling in hot Valley air, spray foam is often the only material that seals as well as insulates. The irregular envelopes left by decades of ad-hoc Add-A-Level conversions mean standard batt can’t create a continuous barrier. Closed-cell foam on the roofline turns an unvented attic into conditioned space – important here because the cooling load on attics is extreme. Open-cell is the pick for interior walls and sound dampening near busy corridors. See Spray Foam Insulation in North Hills for the full material comparison.

Blown In Insulation in North Hills
Blown in insulation in North Hills usually means correcting what was never done right in the first place: filling an old attic that has R-11 batts squashed to R-5, or adding a continuous thermal blanket over uneven framing. The homes here – 1950s and 60s tract ranches – were under-insulated the day they were built, and forty or fifty Valley summers have made it worse. Blown in fiberglass or cellulose flows into the low spots, the stud bays, and the tight eaves that batts leave open. We run the service through our Blown In Insulation crew, and most North Hills attics are done in a morning.
Loose Fill Insulation
Signs you need it
Your attic insulation sits below the top of the joists, or you can feel heat radiating from the ceiling on summer afternoons.
What it costs in North Hills
Loose fill insulation in a typical North Hills attic runs $1,200 – $2,800, depending on depth and square footage.
How we do it
We air-seal the attic floor penetrations, mark the final depth, and blow loose material evenly across the entire attic floor to the target R-value.
Cellulose Insulation
Signs you need it
Your older ranch home has settled or failed attic insulation and you want a dense, fire-resistant, recycled-content option.
What it costs in North Hills
Cellulose insulation for a 1,500 – 2,000-square-foot North Hills attic typically falls between $1,500 and $3,200 installed.
How we do it
We load GreenFiber cellulose into the blower, set the coverage rate for the target R-value, and spray it to a consistent depth, dense-packing wall cavities where needed.
Blown In Attic Insulation
Signs you need it
Rooms under a flat-roofed addition overheat in summer, or your attic has half-finished areas with gaps around the framing.
What it costs in North Hills
Blown in attic insulation in North Hills averages $2,000 – $4,000 for a full removal-and-reinstall on a larger attic.
How we do it
We remove failed material, seal every penetration, install baffles where needed, and blow new insulation to full depth with a second pass over the eaves.
Blown In Fiberglass Insulation
Signs you need it
You want a clean, non-settling loose fill that holds its R-value in a low-clearance North Hills attic.
What it costs in North Hills
Blown in fiberglass in North Hills runs $1,800 – $3,600 for a typical 1,800-square-foot attic.
How we do it
We choose Knauf or CertainTeed fiberglass based on the R-value target, air-seal first, then blow the material with a coverage card so depth never drifts.
What Blown In Insulation Costs in North Hills
| Item | Typical range in North Hills |
|---|---|
| Loose fill attic retrofit (1,500 sq ft) | $1,200 – $2,800 |
| Cellulose dense-pack walls + attic | $1,500 – $3,200 |
| Blown in fiberglass full attic | $1,800 – $3,600 |
Does blown in insulation settle over time in North Hills heat?
Quality blown in fiberglass installed to the correct coverage rate settles less than 2%, even through Valley heat cycles. Cellulose settles slightly more and is installed with that factored in. Call (866) 271-1602 for a site-specific assessment.
Can you blow insulation into walls without opening them up?
Yes, dense-packing through small exterior drill holes works for the uninsulated frame walls common in 1950s North Hills ranch homes. We patch and touch up stucco after. Estimates are free.

We carry Rockwool mineral wool, Knauf and CertainTeed fiberglass, and Icynene spray foam on our North Hills trucks. Because we stock competing brands, we’re not nudging you toward whatever happens to be in inventory. Your attic gets the material that matches its job. See our brands for the full eight-brand lineup.

What North Hills Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Michelle Bennett"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."
— Sarah Fletcher"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Holly Mercer
