Garrett Sloane built Aspen Attic Insulation on a simple rule: every Perris homeowner gets a technician’s name, photo, and written price before anyone knocks. No surprises. No strangers.

Why Aspen Attic Insulation Is Perris’s Preferred Blown In Insulation Company
We’ve worked Perris attics long enough to recognize the stucco ranch with original R-19 fiberglass before we even pull the ladder down. That matters. A crew that thinks every attic is the same will miss the duct runs baking at 160°F or the eave gaps the San Jacinto Valley winds find every winter.
Our reviews from Perris customers consistently mention two things: the tech showed up exactly as promised, with his photo already on their phone, and the price on the invoice matched the price on the estimate. The 365-Day Done Right Promise covers every job in writing. If a repair fails, we come back free. That’s not a slogan. It’s on every contract.
Response time to Perris runs 45 – 60 minutes for standard calls, same day for most blown-in insulation assessments. Emergency service is available when attic temperatures have pushed HVAC systems to failure. Our Perris crews carry eight material brands on every truck, so we match the product to the house, not the other way around.
Blown In Attic Insulation in Perris
Blown In Attic Insulation in Perris means adding loose-fill fiberglass or cellulose into the attic cavity to restore thermal resistance where original insulation has settled, compressed, or degraded from heat cycling. Most Perris homes need this every 15 – 20 years, sooner if the attic has seen pest activity or ductwork disturbance. A typical blown-in attic insulation job in Perris runs $1,800 – $4,200 depending on attic square footage, current insulation depth, and whether we’re topping existing material or starting from the joists.
When Perris Homes Need Attic Top-Ups
The 1980s and 1990s tract homes that dominate Perris were built with R-19 blown-in fiberglass that performs well for about a decade. After repeated summers above 150°F in the attic, that fiberglass settles, shifts, and leaves the top plates and duct runs exposed. We measure depth at multiple points. Anything below R-30 in Perris’s climate is costing you money every month.
What the Job Actually Involves
We seal air leaks at the top plate, recessed light housings, and vent penetrations first. Then we blow new material to R-38 or R-49 depth, depending on your roof structure and budget. The whole process takes four to six hours for most Perris homes. You don’t need to leave. Our techs work clean, in uniform, with photo ID at the door.
Blown In Cellulose Insulation in Perris
Blown In Cellulose Insulation in Perris is our most common recommendation for homeowners dealing with settled fiberglass and the hot-duct problems that come with it. Cellulose is treated borated paper fiber that resists fire, pests, and mold. It packs tighter into irregular cavities than fiberglass and performs better at blocking the wind-driven air infiltration that hits Perris homes every winter afternoon. A typical blown-in cellulose installation in Perris runs $2.00 – $2.80 per square foot, or $2,400 – $4,800 for a standard attic.
Cellulose vs. Fiberglass in Desert Heat
Cellulose doesn’t degrade as quickly under thermal cycling as fiberglass does. In Perris’s 150°F+ attic peaks, that’s a real advantage. It also settles less over time. We source ours from GreenFiber and other leading manufacturers, and we can blow it over existing fiberglass or start fresh after removal.
The Duct-Sealing Pairing
Here’s what most insulation companies miss in Perris: new attic insulation won’t help if your flex duct is leaking 20% of its conditioned air into the attic. We check every joint and seam. When we find leakage, we seal it with mastic and metal tape before blowing cellulose. The homeowner gets one invoice, one crew, one visit. That’s how you actually fix a hot back bedroom.
Trusted Brands We Service in Perris
Our Perris trucks stock materials from Johns Manville, Knauf, Rockwool, and CertainTeed, among others. We don’t show up with whatever the warehouse had in bulk that week. We match the fiber type, density, and R-value to your specific attic condition, roof pitch, and ventilation setup. Because we carry multiple brands, we can source same-day if a job calls for something specialized. Perris homeowners aren’t left waiting while we order from out of state. The right material goes in the first time, and it’s specified on your written estimate before we start.
Common Blown In Insulation Problems We See in Perris Homes
- Settled fiberglass in 1980s – 1990s tract homes. Original R-19 blown-in fiberglass near the 215/74 interchange routinely compresses to R-11 or less after years of 150°F+ attic cycles. The top plates show bare, and duct runs sit in unconditioned air with no thermal protection.
- Baked flex duct in uninsulated attics. Flex duct routed through Perris attics reads 158 – 160°F by late August. Without duct sealing, you’re cooling the attic instead of the living room. Blown-in insulation helps, but only if the ductwork is sealed first.
- Wind-driven infiltration at eaves and vents. Perris’s persistent afternoon San Jacinto Valley winds push cold air through gaps that adequate insulation depth alone can’t stop. Cellulose packs tighter at these pressure points than settled fiberglass.
- Disconnected or crushed duct runs from attic traffic. Homeowners and prior contractors walking through Perris attics have crushed flex duct or pulled connections loose. We find this constantly in older ranch homes off Ethanac Road and north of the 74.

FAQs About Blown In Insulation in Perris
It is thinner. Original blown-in fiberglass in Perris’s 1980s – 1990s homes settles and degrades from repeated exposure to attic temperatures above 150°F. By late August, what started as R-19 often performs like R-11. The material hasn’t disappeared, but it’s compressed and shifted, leaving bare spots at the top plates and around duct runs. We measure actual depth and density to tell you exactly what you’ve got. Call (864) 428-1615 for a free attic assessment.
Yes, if your flex duct runs through the attic. In Perris homes near the 215/74 interchange, we’ve measured duct surface temperatures at 158°F while the flex joints leak 15 – 25% of conditioned air into the attic. New insulation won’t fix that. We seal first, then insulate. The combined approach is what actually drops your cooling load and fixes hot back bedrooms. We price both together on one written estimate.
Fiberglass is lighter, cheaper upfront, and works well in new construction. Cellulose packs denser, blocks air infiltration better, and resists the thermal cycling that degrades Perris attics. For Perris’s wind-driven winter drafts and 150°F summer peaks, we usually recommend cellulose for retrofits. Both materials are fire-rated and pest-treated. We’ll show you samples and explain the cost difference before you decide.
Sometimes, but not always. If the problem is settled insulation with intact ductwork, a top-up to R-38 often solves it. If your flex duct is leaking or baking in 160°F attic air, insulation alone won’t help. We test duct pressure and surface temperatures during our assessment. The fix might be insulation plus sealing, or a radiant barrier. You’ll know before we start. Call (864) 428-1615 to find out what’s actually wrong.
The San Jacinto Valley winds push cold air through eave vents, ridge gaps, and any unsealed penetrations. Settled fiberglass lets that air pass through. Dense-packed cellulose blocks it. We also check baffle placement and vent sealing as part of every Perris installation. Insulation isn’t just depth. It’s an air barrier too. We build both.
