West Hills isn’t a one-size-fits-all insulation market. Homes here sit on canyon-shaded lots, custom builds from the 1960s and 70s, and south-facing exposures that get hammered by afternoon sun while the north side stays damp and cool. That’s why we treat every Attic Insulation job as a diagnostic, not just a material drop.

Radiant Barrier in West Hills
Radiant Barrier in West Hills is one of the most effective upgrades a homeowner can make, especially on south-facing roofs that absorb full afternoon sun during September and October heat waves. A radiant barrier is a reflective material installed under the roof deck or over existing attic insulation. It reflects radiant heat away from the attic space rather than letting it soak through the roof and radiate down into your living areas.
Why South-Facing Roofs Need It
West Hills lots run long and deep, often backing up to the Upper Las Virgenes Canyon Open Space. The south-facing roof planes on those homes get direct sun from late morning until sunset. A radiant barrier can cut attic temperatures by 20 to 30 degrees on a triple-digit day, which means your air conditioner stops fighting heat that never should have entered the home in the first place.
What It Costs Here
Radiant barrier installation in West Hills typically runs $1,200 to $2,800 for a standard attic, depending on roof pitch, attic accessibility, and whether we’re installing it over existing insulation or as part of a full insulation replacement. Pairing a radiant barrier with blown-in insulation is the most common approach we recommend for canyon-view homes with vaulted ceilings.
Attic Cleaning Services in West Hills
Attic Cleaning Services in West Hills are about more than tidiness. They’re about air quality and insulation performance. Santa Ana winds push fine dust and debris through unsealed attic penetrations, and over years that dust settles into existing insulation, compresses it, and reduces its R-value while degrading the air you breathe inside the home.
What We Remove and Seal
Our crews remove old, dirty insulation, rodent debris, and accumulated dust, then assess the attic floor for gaps around recessed lights, plumbing vents, and wire penetrations. In West Hills homes built before air sealing was standard practice, those gaps are everywhere. We air-seal before adding new insulation so the Santa Anas don’t undo the work in a single windy week.
When Cleaning Makes Sense
If your home had a rodent problem, a roof leak, or simply decades of dust accumulation, cleaning before adding insulation is the right call. Blowing new insulation over compacted, contaminated material wastes money. Attic cleaning in West Hills typically runs $800 to $1,800, and we always pair it with a written assessment of what your attic actually needs afterward.

Common Attic Insulation Problems We See in West Hills Homes
- California corners creating cold stripes. Three-stud corners with no insulation behind the drywall leave ghostly cold lines on walls in winter. Our infrared inspections spot them immediately, and we can dense-pack those corners during a top-up or replacement.
- Vaulted ceilings with almost no insulation above them. Many West Hills living rooms and family rooms have vaulted ceilings original to the 1960s and 70s build, with R-11 or less overhead. That’s why those rooms are freezing in January and sweltering by 3 p.m. in August.
- Uninsulated garage conversions and bonus rooms. Rooms built over unconditioned garages or added as bonus spaces rarely have proper floor insulation. Heat radiates up through the floor in summer, and in winter those rooms never seem to hold warmth.
- Santa Ana dust intrusion through unsealed penetrations. Fall winds force fine dust through gaps around recessed lights, attic hatches, and plumbing vents. Stored items get coated, and indoor air quality drops noticeably during Santa Ana events.

FAQs About Attic Insulation in West Hills
Because West Hills sits at the base of the Upper Las Virgenes Canyon Open Space, where north-facing, tree-covered slopes stay damp and cool while south-facing exposures bake in 100-degree Santa Ana heat. Within a single home, that means rooms on the south side gain heat all afternoon while north-side rooms stay shaded and cool. The fix is zoned attic insulation and air sealing, not just adding fiberglass evenly across the whole attic. Call (559) 295-5362 and we’ll diagnose exactly where your thermal imbalance is coming from.
California corners are three-stud framing corners with no insulation behind the drywall. In winter, those corners let cold air transfer through the framing, creating cold stripes on walls that our infrared inspections pick up clearly. Most West Hills homes built in the 1960s and 70s have them, and they’re rarely addressed by standard insulation jobs. We dense-pack those corner cavities during top-ups or replacements, which eliminates the cold stripes and tightens the home’s thermal envelope.
If your vaulted living room or family room feels noticeably hotter or colder than the rest of the house, the insulation above it is almost certainly inadequate. Many West Hills ranch homes and two-story traditionals from the 1960s and 70s have vaulted ceilings with R-11 fiberglass batts or less, and no air barrier. We can inspect the cavity depth from the attic side, measure existing R-value, and tell you exactly what’s up there. On a recent 1970s ranch near the Upper Las Virgenes Canyon Open Space, our crew found exactly that: vaulted living room ceilings with only R-11 and no air barrier. We removed the old material, air-sealed the attic floor, blew in R-38 GreenFiber cellulose, and installed a radiant barrier on the south-facing roof deck. The upstairs afternoon temperature dropped by 12 degrees.
Yes, and it’s one of the highest-impact upgrades for south-facing roof planes in West Hills. A radiant barrier reflects heat away from the attic before it ever enters, cutting attic temperatures by 20 to 30 degrees on triple-digit days. During September and October, when Santa Anas push temperatures into the 90s and 100s, a radiant barrier means your air conditioner isn’t fighting heat that never needed to be in the house. Call (559) 295-5362 for a free estimate with exact pricing.
Yes, if your attic has decades of accumulated dust, rodent debris, or compressed, dirty insulation. Blowing new insulation over contaminated material reduces its R-value and locks in air quality problems. In West Hills, Santa Ana winds force dust through unsealed penetrations every fall, so cleaning and air sealing should happen together, before new insulation goes in. We’ll give you a written scope and price for both, so there are no surprises.
