Insulation Company in North Hills, CA
Blown in insulation solves the most common problem we see in North Hills homes: attics that turn into ovens by 2 p.m. and bedrooms that never cool down. The 91343’s ranch-era houses, most built between the 1950s and 1970s with low-pitch roofs and minimal original batt, respond especially well to dense-packed cellulose and loose-fill fiberglass because both materials fill odd cavities and settle around the shallow, hard-to-reach spaces this housing stock is known for. We’re Even Air Insulation, and we’ve served North Hills since 2018. Call (855) 362-0195 for a free estimate on any insulation project.
Why North Hills Homes Are Different
North Hills sits on the southern flank of the Santa Susana and Granada Hills ridge, which means the sun spends a lot of time hammering west-facing roof planes that have almost no tree cover. Attic temperatures above 140°F are routine from July through September. That heat doesn’t just sit in the attic; it radiates down through the ceiling drywall into living spaces, and the air handler in a typical ranch home pulls some of that overheated attic air into the duct runs. The result is a house that feels ten degrees warmer than the thermostat says, with the AC running nonstop.
Most North Hills homes are single-story tract and ranch builds from the 1950s through 1970s. Low-pitch and flat roofs dominate, especially in older sections of the 91343. Many attics lack ridge vents entirely, and the original soffit vents are often painted over or blocked by years of leaf debris. We regularly open access hatches to find one thin layer of matted, degraded fiberglass batt – maybe R-11 where R-38 or better is now standard. Post-1994 seismic retrofit work on many of the same homes means the attic framing and ceiling planes have been modified; insulation installed after those retrofits rarely got the attention the original build did. That’s the North Hills job: fix ventilation and air sealing first, then add insulation.
Our Main North Hills Services
Two services account for most of the calls we take from North Hills homeowners: attic insulation and spray foam. Each one addresses a different failure mode in this housing stock, and each gets its own dedicated page with local pricing and specifics.
Attic Insulation in North Hills
Attic insulation is the highest-return energy upgrade most homes in North Hills can make. The shallow, vent-challenged attics typical of 91343 ranch builds usually need more than extra material: baffles to restore soffit airflow, air sealing around ceiling penetrations, and often a radiant barrier to cut solar gain through the roof deck. We inspect the existing venting before we prescribe anything. Learn more on our Attic Insulation in North Hills page.
Spray Foam Insulation in North Hills
Spray foam isn’t always the answer – but when it is, we have two professional-grade options. In North Hills, closed-cell foam earns its keep on flat-roof homes where headroom is tight and R-value per inch matters. Open-cell foam works well for interior wall cavities and sound control in walls shared with busy streets like Sepulveda or Nordhoff. We carry both Icynene and Demilec formulations.

Blown In Insulation in North Hills
Blown in insulation is the workhorse solution for North Hills attics. Dense-packed cellulose and loose-fill fiberglass both do what batt insulation often can’t in the 91343: they flow into the irregular cavities, shallow eaves, and tight corners of ranch-era low-pitch roofs, covering ceiling joists and filling voids that leave bare sheetrock exposed to 140°F attic air. For most North Hills homes with a vented attic, loose-fill blown in material delivers the most consistent coverage per dollar. We install blown in insulation using GreenFiber cellulose and Johns Manville or Knauf fiberglass, depending on the attic’s condition and the homeowner’s goals. Here’s how our Blown In Insulation work breaks down in North Hills.
Cellulose Insulation
Signs you need it
Rooms that heat up fast after noon, especially on the west side of a North Hills ranch, or attic temps you can feel radiating through the ceiling by late afternoon.
What it costs in North Hills
Blown-in cellulose attic insulation in North Hills typically runs $1.25 to $2.50 per square foot installed, with most 1,200-square-foot attics landing between $1,500 and $3,000, depending on depth, access, and existing material removal.
How we do it
We air-seal the ceiling plane, install or repair baffles at the soffits, then dense-pack or loose-fill GreenFiber cellulose to the target depth using a truck-mounted blower, checking coverage with depth markers as we go.
Loose Fill Insulation
Signs you need it
Uneven insulation depth or bare patches in an older North Hills attic, often visible after a termite or roof inspection, or when the original 1960s batt has compressed to a fraction of its rated value.
What it costs in North Hills
Loose-fill fiberglass in a North Hills attic averages $1.00 to $2.00 per square foot installed, so a typical 1,000-square-foot attic runs $1,000 to $2,000 for a fresh, even layer.
How we do it
We remove or level the old material if needed, then blow loose-fill fiberglass to a consistent depth across the entire attic floor, including over the ceiling joists and into corners that baling can’t reach.
What Blown In Insulation Costs in North Hills
| Item | Typical range in North Hills |
|---|---|
| Blown-in fiberglass attic insulation | $1.00 – $2.00 per sq ft |
| Blown-in cellulose attic insulation | $1.25 – $2.50 per sq ft |
| Walls (dense-pack cellulose, existing home) | $2.50 – $4.50 per sq ft of wall area |
Prices for North Hills shift based on attic depth, access difficulty, whether old material has to be removed, and how much air sealing the attic needs. We quote upfront and flat – the number we give you before the crew arrives is the number on the invoice.
Is blown in insulation worth it in North Hills?
Yes. Most North Hills homes are cooling-dominated, and blown in insulation cuts the attic-to-ceiling heat transfer that drives summer AC demand. Homeowners typically notice the difference in west-facing bedrooms within the first hot week.
Can you blow insulation into walls without tearing out drywall?
Yes. Dense-pack cellulose can be installed through small holes drilled in each stud bay, usually from the exterior, then patched. It’s a common retrofit in 1950s-1970s North Hills and 91393 homes that never had wall insulation. Call (855) 362-0195 for an attic or wall assessment.
