Insulation Company in North Hills, CA
Blown in insulation is the most common fix we handle in North Hills, and for good reason. Most homes here were built between the late 1940s and the 1970s, when insulation standards were thin by today’s measures, and decades of Valley heat have settled or compressed whatever was originally installed. The result is an attic that lets summer heat pour straight into living spaces. Snug Insulation matches the right blown-in material to each North Hills attic, and our crews understand the low-slope roofs and tight clearances that make these mid-century houses different to work in.

Why North Hills Homes Are Different
North Hills sits in one of the San Fernando Valley’s hottest inland pockets. Summer days regularly push past 100°F, and that heat doesn’t just hover outside, it radiates through the roof deck into the attic, where temperatures can climb above 140°F in a home with degraded insulation. Most of the housing stock is single-story stucco tract homes from the 1950s and 60s, built with low-pitch roofs and shallow attic spaces. That combination makes radiant heat transfer the dominant comfort problem, far more than winter heat loss. We routinely find original fiberglass batts that have been compressed or shoved aside by decades of HVAC ductwork, electrical upgrades, and attic storage. The original R-value on a 1960s North Hills home might have been R-11 or R-13, and after 50-plus years of settling, it’s often performing at half that. Attic insulation upgrades here aren’t a comfort bonus; they’re the highest-leverage improvement a homeowner can make against Valley heat.
Our Main North Hills Services
Two services account for most of the calls we get from North Hills homeowners. Each one has a dedicated page that covers what the work involves, what it costs, and how it’s done.
Attic Insulation in North Hills
Attic insulation is the first thing we check in a North Hills home because it’s where the biggest energy losses happen. With low-slope roofs and shallow attics, many of these 1950s and 60s tract homes have limited space to work, which is why a proper assessment matters before any material goes in. We inspect what’s already there, measure the settled depth, and then recommend the right R-value for a Valley climate that sees 100°F days for months at a time. Read the full breakdown here: Attic Insulation in North Hills.
Spray Foam Insulation in North Hills
Spray foam earns its keep in North Hills because it air-seals while it insulates, which matters in older stucco homes where gaps around top plates, can lights, and duct penetrations let attic heat into the conditioned space. Open-cell foam works well for interior walls and sound dampening, while closed-cell adds structural strength and a vapor barrier, useful in tight mid-century attics. We work with Icynene and Demilec systems, two of the most specified spray foam brands in performance building. Full details here: Spray Foam Insulation in North Hills.

Blown In Insulation in North Hills
Blown in insulation is the most practical upgrade for most North Hills homes because it fills the irregular cavities and tight corners of shallow mid-century attics far better than batts ever could. Loose fill gets worked into every gap, building depth and R-value without tearing out the existing insulation first. In North Hills, where attic temperatures routinely exceed 140°F in summer, a properly blown attic can cut the heat load on the whole house. We’re a blown-in specialist, not a general contractor, and we match the loose-fill material to the attic rather than forcing one product on every job. For a deeper look at the service line, see Blown In Insulation.
Cellulose Insulation
Signs you need it
The existing attic insulation is patchy, settled, or thin enough that you can see the ceiling joists, and upstairs rooms get noticeably hotter than the rest of the house by early afternoon.
What it costs in North Hills
Cellulose blown-in for a standard North Hills attic typically runs $1.20 to $2.10 per square foot, with most homes landing around $1,500 to $2,600 for a full top-up.
How we do it
We prep the attic by sealing bypasses and baffling the vents, then blow GreenFiber cellulose to a uniform depth that hits the R-value target, usually R-38 in this climate.
Blown In Fiberglass Insulation
Signs you need it
The old batts are compressed or displaced from years of electrical and HVAC work, leaving bare spots across the attic floor that you can feel as hot zones in the rooms below.
What it costs in North Hills
Blown-in fiberglass in North Hills runs $0.90 to $1.80 per square foot installed, so a typical 1,200-square-foot attic lands between $1,100 and $2,200.
How we do it
We remove or level what’s salvageable, air-seal the attic floor, then blow premium fiberglass loose fill across the whole surface to a consistent, measured depth.
What Blown In Insulation Costs in North Hills
| Item | Typical range in North Hills |
|---|---|
| Cellulose insulation | $1.20 – $2.10 per sq ft |
| Blown-in fiberglass | $0.90 – $1.80 per sq ft |
| Loose fill attic top-up | $1,500 – $2,600 total |
Two things push blown-in insulation costs up in North Hills: shallow attics with limited access, which slow the job down, and the need to air-seal first, which adds labor but dramatically improves the final result. We quote an upfront, line-item price before any work begins.
How long does blown in insulation last in North Hills?
Loose fill insulation lasts 20 to 30 years in North Hills, but the Valley heat settles it over time, which is why a depth check every decade is worth doing. Settled material loses R-value even though the insulation itself is still intact. Call (844) 241-0737 if you suspect yours has thinned out.
Can you blow in insulation over old batts in North Hills?
Yes, blowing loose fill over existing batts is standard practice in North Hills, as long as the old material isn’t wet, moldy, or full of rodent damage. We inspect the attic first, then blow to a combined depth that hits the target R-value. Call (844) 241-0737 for a free attic check.
