Insulation Company in Perris, CA
Blown in insulation is the most common request we field from Perris homeowners, and for good reason: it settles into the odd cavities of mid-century ranch homes in 92570 and tops off the thin, code-minimum attic layers in 92571 tract houses faster than any other method. Perris sits in a hot inland valley where summer attic temperatures regularly exceed 130°F, so under-insulated homes here bleed cooling dollars at a rate coastal contractors rarely see. Hollywood Insulation Co installs blown in fiberglass and cellulose, spray foam, and batt systems, matching the material to the house rather than the truck. Call (866) 605-6949 for a free estimate.
Why Perris Homes Are Different
Perris is really two housing markets wearing one ZIP code. The 92570 core and the county pockets around it hold a large stock of 1950s-1970s single-story ranch homes, many with original insulation that has settled, compressed, or was never installed to any meaningful depth. A surprising number of these older Perris attics have R-11 or less, which is roughly a third of what the Department of Energy recommends for this climate zone. The 92571 growth area tells a different story: 1990s-2000s and newer two-story tract homes that technically passed code at build time, but with builder-grade insulation that meets minimums without accounting for how brutal the Perris Valley summer actually is. The wide day-night temperature swing here, with cool desert-influenced winter nights and 100°F-plus summer days, means insulation has to handle both directions of heat transfer, not just keep heat out. Homes here are overwhelmingly stucco-clad with low-pitch or tile roofs, which soak up sun all afternoon and radiate that heat straight into whatever insulation sits beneath.
Moisture is less of an enemy in Perris than it is on the coast, but the dry heat brings its own problem: fiberglass and cellulose that have been baked for a decade or more lose loft and lose R-value. We regularly find attics in Perris that have the right material installed at the wrong depth, or the wrong material for a valley-climate house.
Our Main Perris Services
Perris homeowners call us most often about two things: fixing under-insulated attics and air-sealing the building envelope with spray foam. Here’s what each job looks like in this city.
Attic Insulation in Perris
Attic insulation in Perris is the highest-impact upgrade most homes can get, because the attic is where the valley heat concentrates first. We routinely pull back old batts in 92570 ranches and find gaps, settling, and rodent damage that has quietly been costing the homeowner money for years. In 92571, the problem is usually just as fixable: the original fiberglass was installed to code minimum, which simply isn’t enough for a Perris summer. We install blown in fiberglass, blown in cellulose, or batt systems depending on the attic configuration and existing conditions, and we always check for the air leaks that make insulation underperform. Attic Insulation in Perris details what a full attic assessment involves.

Spray Foam Insulation in Perris
Spray foam solves the problem Perris homeowners feel most: hot spots in upstairs bedrooms and rooms over the garage that never seem to cool down, no matter how low the thermostat goes. Closed-cell foam adds structural rigidity and an air seal that batt and loose-fill cannot match, which matters in stucco homes that face afternoon sun on multiple elevations. We install both Icynene and Demilec systems, open-cell for interior air sealing and sound control, closed-cell for maximum R-value per inch in tight rafter bays. Spray Foam Insulation in Perris covers the differences between open-cell and closed-cell in this climate.

Blown In Insulation in Perris
Blown in insulation in Perris is our most-specified service because it fits the two housing realities here better than any other single method. In older 92570 ranches with shallow, settled fiberglass, blown in cellulose fills the voids and brings the attic up to true performance without a full tear-out. In newer 92571 tract homes, blown in fiberglass tops off thin builder-grade layers quickly and cost-effectively. The dry Perris climate works in your favor here: blown in material holds its loft well when it isn’t fighting moisture, so it keeps performing season after season. You can learn more about the method itself on our Blown In Insulation hub page.

How we do it

Loose Fill Insulation
Signs you need it
Your existing insulation is compressed, uneven, or missing entirely in hard-to-reach areas like knee walls and low-slope attic sections.
What it costs in Perris
Loose fill insulation in Perris costs $1.50-$4.00 per square foot depending on material and R-value target.
How we do it

What Perris Customers Say
"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."
— Miguel Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"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."
— Cole Sullivan
