Why Aspen Attic Insulation Riverside Is Rubidoux’s Preferred Blown In Insulation Company
We’ve worked in enough Rubidoux attics to know what’s up there before we even lift the hatch. Homes here were mostly built between the 1950s and early 1980s, back when R-11 fiberglass batts were considered plenty. Half a century later, those batts are compressed, dust-filled, and doing almost nothing. Our customers in Rubidoux call us because someone on their street already used us, or because they saw our marked van on the job and asked the neighbor who did the work. That’s how most of our business comes in here. Word gets around.
Every tech we send to Rubidoux follows the Threshold Standard: background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. You’ll know exactly who’s walking up your driveway. If anyone else shows up, the visit is free and we make it right. That’s not a slogan. It’s company policy, in writing, since 2002.
Garrett Sloane runs our crew. He grew up in the Inland Empire heat and he’s been in attics like yours since before he could legally drive. He trains every tech the same way: show the homeowner what you found, explain what it will cost in plain numbers, and don’t start anything until they’ve signed off on a written price. No surprises, no “while we were up there we noticed” add-ons after the fact.
Response time to Rubidoux: same-day or next-day in most cases, 48 hours worst case during peak summer demand. Estimates are free. The price we quote is the price you pay, and it’s covered by our 365-Day Done Right Promise: a full year, in writing, covering labor and materials. If the insulation doesn’t perform the way we said it would, we come back and fix it free.
Blown In Attic Insulation in Rubidoux
Blown In Attic Insulation is the single most effective upgrade we do for Rubidoux homes built before 1980. The process involves blowing loose fibers (fiberglass or cellulose) through a hose into the attic cavity, filling every gap, void, and odd corner that batts can’t reach. In a Rubidoux attic, that matters more than most places. Your roof deck hits 140°F or higher on a 100°F day. Without proper ceiling insulation, that heat radiates straight down into your living space. Blown-in material creates a continuous thermal blanket that stops that transfer.
Most Rubidoux attics we see have 3 to 6 inches of original rock wool or compressed fiberglass, which gives you roughly R-9 to R-19. Current energy codes recommend R-38 to R-49 for our climate zone. We typically blow in 14 to 18 inches of material to reach R-38 or R-49. Cost for a standard 1,200 to 1,500 square foot attic in Rubidoux runs $2,200 to $4,200, including removal of the old degraded material if needed.
Air Sealing Before We Blow
Blown insulation without air sealing is half a job. In Rubidoux attics, the gaps around top plates, can lights, plumbing vents, and the chimney chase let super-heated attic air bypass the insulation entirely. We seal those penetrations before we blow. It’s the difference between an attic that reads R-38 on paper and one that actually keeps heat out of your bedroom.
What to Expect During Installation
Most attic retrofits in Rubidoux take 4 to 7 hours. We lay down hoses in your yard or driveway, set up a blower machine, and one tech works in the attic while another feeds material. You hear the machine running, but there’s no mess inside your living space. We cover the attic access and clean up before we leave. The written price you approve before we start is the final price.
Blown In Cellulose Insulation in Rubidoux
Blown In Cellulose Insulation is the material we recommend most often for Rubidoux attics, especially in older homes near the Santa Ana River bottom. Cellulose is made from recycled paper treated with borate, which adds fire resistance and deters pests. That matters here. In Rubidoux, rats and squirrels from the river corridor get into attics and nest in insulation. Borate-treated cellulose makes that space less inviting than bare fiberglass. It also packs tighter around odd framing and plugs small gaps better than blown fiberglass.
For a Rubidoux homeowner dealing with baking upstairs bedrooms, blown cellulose in the attic at R-38 to R-49 typically costs $2,400 to $4,600, depending on square footage and whether we’re removing old contaminated batts first. If rodents have been in your attic, removal is not optional. Rodent-soiled insulation is a health issue and it doesn’t insulate worth a damn after being trampled and nested in.
Contamination and Removal
If you’ve had rodents in the attic, we won’t blow new material over old contaminated insulation. We remove the affected material, sanitize what’s practical, air-seal the entry points, and then blow in fresh cellulose. This is standard practice on our Rubidoux jobs. The extra removal step adds $600 to $1,400 depending on attic size and the extent of the damage.
Cellulose in Walls of Older Rubidoux Homes
Many 1960s ranch houses in Rubidoux have zero wall insulation. Dense-packed cellulose can be blown into wall cavities through small holes drilled from the exterior or interior, without tearing off drywall. We do this job regularly here. Wall retrofits typically run $2.50 to $4.00 per square foot of wall area, and the difference in afternoon comfort is noticeable within days.
Trusted Brands We Service in Rubidoux
We’re not married to one manufacturer. We stock and install blown-in material from Owens Corning, Johns Manville, and GreenFiber, and we match the product to your specific attic conditions, not to what’s cheapest on our shelf. Owens Corning fiberglass blows light and clean for open attic floors. GreenFiber cellulose is our go-to for Rubidoux homes with pest pressure and odd framing. Johns Manville offers a dense-pack option for wall cavities. If you call us for Blown In Insulation in Rubidoux, we’ll tell you which material makes sense for your house and why. We keep all three stocked for same-week jobs.
Common Blown In Insulation Problems We See in Rubidoux Homes
- Compressed legacy rock wool in 1950s-70s attics: Original rock wool settles to 2 to 3 inches over decades, dropping to R-6 or worse. Heat pours through the ceiling, and the AC runs nonstop without making the upstairs comfortable. The fix is removal and a fresh blow to R-38 or R-49.
- Rodent damage from the Santa Ana River bottom: Rats and squirrels chew through soffit vents and ductwork, nest in the insulation, and leave urine and droppings throughout the attic. Blown-in insulation has to come out and be replaced. Borate-treated cellulose helps keep them from coming back.
- Insulation installed without air-sealing: Many Rubidoux homes had blown-in insulation added decades ago, but nobody sealed the top plates, can lights, or chase openings first. Super-heated attic air shortcuts around the insulation. Sealing before blowing is what makes the difference you can feel the same week.
- Uneven coverage from DIY or handyman jobs: We see attics where someone blew insulation themselves and missed entire sections over the garage or over the stairwell. The upstairs bedroom above that gap bakes while the rest of the house is fine. We use a blower with consistent pressure and check coverage with depth markers as we go.

FAQs About Blown In Insulation in Rubidoux
For Rubidoux’s climate, you want 14 to 18 inches of blown-in material to reach R-38 to R-49. That’s the thickness that keeps attic heat from radiating into your living space when summer temps pass 100°F. Anything less than 12 inches and you’ll still feel the heat upstairs. Call (510) 896-3857 and we’ll measure what you have and tell you what it’ll take.
Yes, but only after the contaminated insulation is removed and the entry points are sealed. Blowing new cellulose over rodent-soiled material doesn’t fix the problem. We remove the old insulation, seal the gaps where rats and squirrels got in, and then blow in borate-treated cellulose that makes the attic less inviting for pests. The full process costs more than a simple blow, but it’s the only way to do it right.
Yes. Dense-packed cellulose goes into wall cavities through small holes drilled from outside or inside, usually 1 to 2 inches wide. We patch and touch up after. Most 1960s ranch houses in Rubidoux have empty wall cavities, and filling them makes a noticeable difference in how long the house holds cool air. Wall retrofits run $2.50 to $4.00 per square foot of wall area.
Blown cellulose and blown fiberglass in an attic will perform for 20 to 30 years in Rubidoux’s heat, provided the attic stays dry and no rodents get in. The bigger issue here is that older insulation was already inadequate when it was installed. If your attic has original 1950s-70s material, it’s already past its useful life regardless of how long the product itself would last.
Yes, and that’s the most common complaint we solve in Rubidoux. We worked on a 1960s ranch home near Flabob Airport where the upstairs bedrooms baked every afternoon despite the AC running nonstop. The attic had less than 3 inches of compressed rock wool and a squirrel had nested in the eaves, scattering debris over the ceiling joists. Our crew air-sealed the rim joists, removed the contaminated material, and blew in 14 inches of GreenFiber cellulose to reach R-38. The owner told us the upstairs stayed ten degrees cooler the next week. That’s the difference air-sealing plus the right insulation depth makes.
