Insulation Company in Perris, CA
Blown in insulation is the most common request we get from Perris homeowners, and it’s usually the right call for houses built between 1980 and 2010. The valley heat here doesn’t just make rooms uncomfortable; it bakes attics to 140°F or more, settles old fiberglass, and leaves gaps that air moves through freely. We match the right material, whether that’s cellulose or fiberglass, to how your home was built and where it’s losing conditioned air. Call us at (855) 382-3925 to talk through what your attic actually needs.
Why Perris Homes Are Different
Perris sits in the Perris Valley, an inland basin where summer highs routinely push past 100°F while winter nights can dip toward freezing. That’s not a minor detail for insulation. It means your home’s thermal envelope has to work hard in both directions, keeping heat out during July afternoons and holding it in during January mornings. Attics in the valley’s newer tract homes routinely hit 140 to 150°F, which is why radiant barriers and proper attic ventilation matter just as much as R-value here. Anyone who treats insulation as a one-material, one-number job misses what Perris actually demands.
The housing stock adds another layer. Much of Perris is 1980s to 2000s stucco tract housing, plus a large manufactured and mobile home segment in the older 92570 areas. Those mobile homes have thin factory walls and belly-board or underfloor insulation that fails differently than site-built attic batts. In the older parks and ranch parcels around 92570, we regularly find original factory underbelly insulation sagging or torn apart by rodents beneath single-wides. That’s a repair that rarely comes up in newer subdivisions, but it’s routine for our crews here. Meanwhile, the growing 2010s and 2020s subdivisions in 92571 often have code-minimum attic insulation that was never topped up, leaving brand-new homes with the same hot-afternoon bedrooms as homes twice their age.
Santa Ana wind events also drive dust into attic and wall cavities throughout the valley. That dust settles into insulation, reduces its effectiveness over time, and makes sealing penetrations before blowing in new material a non-negotiable step. We’ve learned to account for this in Perris specifically.
Our Main Perris Services
We offer attic insulation and spray foam as full-service options across Perris, and many homeowners need some combination of both depending on what we find during inspection.
Attic Insulation in Perris
Attic insulation in Perris means dealing with extreme attic temperatures, settled or thin existing batts, and the dust that Santa Ana winds push into vented attics. We inspect what’s already up there, air-seal around can lights, wiring, and top plates, then install the right insulation for your home’s construction, whether that’s blown-in fiberglass, cellulose, or new batts. For homeowners in 92570 with older homes and for newer 92571 subdivisions alike, the goal is the same: an attic that actually slows heat transfer during valley summers. Read more on our Attic Insulation in Perris page.
Spray Foam Insulation in Perris
Spray foam insulation solves problems that fiberglass and cellulose can’t, especially in Perris homes with knee walls, bonus rooms, or ductwork running through unconditioned attics. The high heat in the Perris Valley makes ducts sitting in 140°F attics a major efficiency problem, and closed-cell foam can bring that attic temperature down dramatically. We install Icynene and Demilec open- and closed-cell systems, matched to the specific house rather than sold as a one-size upgrade. Learn what spray foam can do for your home on our Spray Foam Insulation in Perris page.

Blown In Insulation in Perris
Blown in insulation in Perris is the fastest, cleanest way to restore or upgrade an attic that’s been losing the temperature battle for years. Most homes here from the 1980s and 1990s were built with a thin layer of fiberglass that settles, compresses, and stops doing its job long before anyone notices. In Perris specifically, the intense attic heat accelerates that breakdown, and dust from Santa Ana winds works its way into the existing material, making replacement more effective than topping off. We use both cellulose and fiberglass blown-in systems, matched to your home’s framing, existing insulation, and budget. For a deeper look at how blown-in works as a method, see our Blown In Insulation hub page.
Loose Fill Insulation
Signs you need it
Rooms over the garage or on the west side of the house run noticeably hotter than the rest of the home, or your energy bills climb every summer no matter how high you set the thermostat.
What it costs in Perris
Loose fill insulation in Perris typically runs $1.35 to $3.10 per square foot installed, depending on depth and material.
How we do it
We air-seal the attic floor around lights, wires, and top plates, then blow in loose fill material to an even, consistent depth that hits your home’s target R-value.
Blown In Attic Insulation
Signs you need it
Your attic insulation is thin, patchy, or covered in dust and rodent droppings, or you can see joists in the attic floor because the old material has settled below them.
What it costs in Perris
Blown in attic insulation in Perris generally costs $1,700 to $3,900 for a typical 1,500 square foot attic, including removal of severely degraded old material where needed.
How we do it
We seal bypasses and penetrations first, then use a mechanical blower to distribute insulation evenly across the attic floor to the depth specified for your home’s age and climate zone.
Blown In Cellulose Insulation
Signs you need it
You want an insulation that’s made mostly from recycled paper, resists air movement better than fiberglass, and fills odd attic cavities without leaving gaps.
What it costs in Perris
Blown in cellulose insulation in Perris typically runs $1.10 to $2.35 per square foot for material and installation.
How we do it
We install GreenFiber cellulose with a dense-pack or loose-fill method depending on the cavity, using equipment calibrated to the correct pounds-per-square-foot density for the space.
What Blown In Insulation Costs in Perris
| Item | Typical range in Perris |
|---|---|
| Loose fill insulation (installed) | $1.35 – $3.10 per sq ft |
| Blown in attic insulation (1,500 sq ft attic) | $1,700 – $3,900 |

Is blown in insulation enough for Perris summers?
Yes, when installed at the right depth and paired with air sealing, blown in insulation handles Perris heat well. The key is using enough material and making sure the attic floor is sealed first, so hot air from the attic doesn’t get pulled into the house through gaps.
Can you remove old, dusty insulation first?
We can remove old insulation when it’s been contaminated by rodents, dust, or water, which happens more often in older Perris homes and mobile home underbellies than people expect. Call (855) 382-3925 for a free attic inspection and an exact quote.

What Perris Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Jason Hoffman"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."
— Colleen Vaughn"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."
— Amanda Sullivan
