Insulation Company in West Hills, CA
West Hills homes need insulation that handles two very different realities: shaded canyon lots that hold damp, cool air against north-facing walls, and open south-facing exposures that bake in 90-plus degree summer heat. Those conditions sit side by side in single homes here, which is why our free estimates for West Hills insulation work start with a walk of the whole property, not just the attic. We install, replace, and remove insulation using materials matched to exactly what your side of the hill does. Call us at (559) 295-5362 when you’re ready for a written price.
Why West Hills Homes Are Different
Most West Hills housing stock was built in the 1960s and 1970s, and the original attics reflect it: thin fiberglass batts, often settled to half their rated depth, and walls with the same problem hidden behind drywall. Ranch homes with vaulted living-room ceilings frequently have almost nothing above the drywall, which makes those rooms the hottest in the house by late afternoon. The larger, custom homes north of the 101 near Upper Las Virgenes Canyon Open Space add another layer: deep, tree-covered lots on north-facing slopes stay damp and cool, while the south side of the same house can sit in full sun for hours. That thermal imbalance isn’t something generic insulation solves – it takes air sealing, specific R-value targets, and an installer who knows the difference between a shaded lot and an exposed one.
You’ll also find homes here with “California corners,” a 1970s framing shortcut that leaves three-stud corners with no insulation behind the drywall. On winter nights dipping into the 30s, those corners show up as ghostly cold lines on interior walls. We spot them with infrared cameras during an estimate and can often treat them without opening the wall.
Fall brings Santa Ana winds through West Hills, pushing dust into attics through gaps around can lights, plumbing vents, and top plates. Attic air sealing matters as much as the insulation itself here, because a windy October week can fill a poorly sealed attic with fine grit that drifts down into living space.
Our Main West Hills Services
West Hills homeowners call us most about two things: upgrading attics that are decades past their useful life, and tearing out old or water-damaged insulation before it causes bigger problems. Each service has its own West Hills page with details, pricing, and a direct line to schedule.
Attic Insulation in West Hills
Older attics in West Hills rarely meet current comfort standards, and the ranch homes with vaulted ceilings are often the worst offenders. We assess the existing depth, check for air leaks, and recommend a target R-value for your specific exposure, whether that means blown-in fiberglass from Owens Corning over existing batts or a full re-insulate. One local detail matters a lot here: shaded canyon lots need different ventilation planning than open hillsides, and we plan for that from the first visit. Get the full breakdown on our Attic Insulation in West Hills page.

Spray Foam Insulation in West Hills
For West Hills homes with uninsulated garage conversions, bonus rooms, or box-bay window overhangs, spray foam is often the only insulation that reaches the odd framing those additions leave behind. Closed-cell foam from brands like Demilec or Icynene also air seals in one step, which matters when Santa Ana winds push dust through every small gap in the building envelope. We’ll tell you honestly whether spray foam is the right call for your project or whether a different material gets you the same result for less. Read more on our Spray Foam Insulation in West Hills page.

Insulation Removal in West Hills
Rodent activity, roof leaks, and decades of dust accumulation are common in West Hills attics, especially in homes that have gone years without insulation upgrades. We remove contaminated or failed insulation, sanitize the attic floor, and prepare the space for fresh material. If you’ve had a wildlife issue in the attic, removal is typically the necessary first step before any new insulation goes in. Our process is clean, contained, and documented with photos before and after. Details are on our Insulation Removal in West Hills page.

Most HOAs in West Hills only review exterior changes, so attic and wall insulation work rarely triggers approval. If you have questions about your specific association’s rules, we can help you flag the job to your management company before we start.
