Insulation Company in Bloomington, CA
Blown in insulation is the most common retrofit we install in Bloomington, and it’s the service most homeowners call us about first. The housing stock here – mostly single-story homes built between the 1950s and 1980s – rarely came with adequate insulation, and what little was installed has often settled or broken down under decades of Inland Empire heat. We’re Riverstone Insulation, and insulation is all we do. Call (866) 950-6425 and we’ll diagnose what your specific house actually needs.
Why Bloomington Homes Are Different
Bloomington sits in the hot, dry heart of the Inland Empire, where summer days regularly cross 100°F and the sun beats down hard on asphalt shingle roofs. Attic temperatures in these older tract homes routinely spike above 150°F when insulation is thin or degraded, which cooks ductwork and breaks down insulation materials faster than you’d see in coastal cities. That’s a pattern our techs see repeatedly in Bloomington’s 1950s-through-1980s neighborhoods, where attics vent poorly in the heat.
The housing stock compounds the problem. Most Bloomington homes are modest single-story wood-frame builds with vented attics and underfloor spaces that were, at best, minimally insulated when they were built. We’re usually retrofitting an older home, which means we’re working around decades of accumulated dust, old wiring, and sometimes degraded original batt material. The work here has to address two things at once: reducing heat gain from that relentless sun and replacing materials that have already started to fail. A generic insulation job won’t hold up the way a material-matched one will, which is why we choose products based on bloomington’s specific heat load, not on what’s easiest to stock.
Our Main Bloomington Services
Most Bloomington homeowners call us about two services: attic insulation and spray foam. Each one has its own dedicated page where we go into detail – here’s a quick look at why each matters in this climate.
Attic Insulation in Bloomington
Attic insulation is the first line of defense against Bloomington’s extreme attic heat. In a poorly vented attic here, temperatures climb past the point where standard insulation performs well, and that heat radiates down into living spaces, forcing your air conditioner to work harder all afternoon. We install blown-in and batt materials across multiple brands, matching the R-value and material type to your attic’s height, venting, and existing condition. If your attic is part of an older single-story home, there’s a good chance the insulation up there has settled well below its original R-value. For the full breakdown, see our Attic Insulation in Bloomington page.
Spray Foam Insulation in Bloomington
Spray foam solves a problem Bloomington homeowners feel every July: air leaks. The wood-frame construction common to Bloomington’s older tract homes leaves gaps around plumbing penetrations, electrical boxes, and top plates that let conditioned air escape and hot air pour in. Closed-cell spray foam seals those gaps while adding serious R-value, and it’s one of the few materials that handles 150°F+ attic heat without losing performance. We install both Icynene and Demilec spray foam systems. Details are on our Spray Foam Insulation in Bloomington page.

Blown In Insulation in Bloomington
Blown in insulation is the fastest way to correct decades of under-insulation in Bloomington’s older single-story homes. We blow loose-fill material into attic floors and wall cavities, filling gaps that batt insulation can’t reach. The job typically takes less than a day, and it’s the most cost-effective retrofit for a Bloomington house built in the 1950s through 1980s that’s still running on its original thin layer of material. Our crews install blown-in fiberglass and cellulose from brands like CertainTeed and GreenFiber – the choice depends on your attic’s condition. You can read more on our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Your attic has settled or patchy coverage with exposed ceiling joists, and your cooling bills stay high even after sealing obvious air leaks.
What it costs in Bloomington
Blown in insulation in Bloomington typically runs $1,400 – $2,400 for a standard attic, with cellulose at the middle of that range due to its higher R-value per inch.
How we do it
We dense-pack GreenFiber cellulose into attic floors or wall cavities using a high-pressure blower, checking depth with gauges to hit your target R-value.
Blown In Attic Insulation
Signs you need it
Rooms on the top floor run noticeably warmer than the rest of the house, or you can see bare spots in the attic where insulation has shifted.
What it costs in Bloomington
Expect to pay $1,400 – $2,400 for a complete blown-in attic retrofit in Bloomington, depending on square footage and the R-value you’re targeting.
How we do it
We prep the attic, air-seal visible penetrations, then blow fiberglass or cellulose to a consistent depth using calibrated equipment.
Blown In Fiberglass Insulation
Signs you need it
Your existing fiberglass batts have compressed or pulled away from the eaves, leaving the attic floor uneven and under-insulated.
What it costs in Bloomington
Blown-in fiberglass for a typical Bloomington attic runs $1,400 – $2,200, with the final number tied to depth and total square footage.
How we do it
We blow loose-fill fiberglass from CertainTeed across the attic floor, building to an even depth that hits the R-rating specified for Bloomington’s heat.
Loose Fill Insulation
Signs you need it
Your attic has old, settled material that’s lost its loft, or you need to top up existing insulation without removing what’s already there.
What it costs in Bloomington
Loose fill blow-in jobs in Bloomington generally fall between $1,400 and $2,400, with final pricing based on cavity depth and access.
How we do it
We load the hopper with your chosen material and blow it into place, working from the farthest corner back to the hatch so coverage is uniform.
What Blown In Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Blown-in attic insulation (standard home) | $1,400 – $2,400 |
| Blown-in fiberglass (attic floor) | $1,400 – $2,200 |
| Blown-in cellulose (attic floor) | $1,500 – $2,400 |
Those ranges assume a typical Bloomington single-story home with reasonable attic access and no major air-sealing work needed. If your attic has old material that needs removal first, or your house has unusually steep roof pitches, the number moves toward the high end.
Is blown in insulation worth it in a 1950s Bloomington home?
Yes. Older Bloomington homes typically have R-19 or less in the attic, and code now calls for much higher levels in this heat. Blown in insulation is the most practical retrofit for those attics, and it pays for itself through lower summer cooling bills.
Can you blow insulation over my existing material?
Usually, yes. If the existing insulation is dry and hasn’t been contaminated by rodents or mold, we can blow new material right over it. We’ll check it during the estimate and tell you if removal is needed. Call (866) 950-6425 to schedule that inspection.
Brands We Service in Bloomington
Riverstone installs products from eight brands, but for Bloomington’s heat and housing stock, we lean on three most often: CertainTeed for blown-in fiberglass, GreenFiber for cellulose, and Rockwool or Icynene when fire resistance or air-sealing matters. Parts are stocked at our Hesperia yard, so most Bloomington jobs don’t wait on shipping. See our brands page for the full portfolio.

FAQs About Insulation Company in Bloomington
Most Bloomington jobs get an estimate within a few days of your call, and installation typically happens within one to two weeks after you approve the quote. Our crews work out of Hesperia, so Bloomington is a regular route for us, not a distant dispatch.
For most retrofit insulation jobs in existing Bloomington homes, no permit is required. New construction or major remodels are different, but a straightforward attic or wall blow-in doesn’t trigger the permit process. If your job does need one, we’ll tell you during the estimate. Call (866) 950-6425 with questions.
It depends on your attic’s condition and how the home is built. Blown-in is the cost-effective fix for most Bloomington single-story homes with vented attics. Spray foam earns its price when you’re sealing air leaks or insulating a cathedral ceiling. We’ll tell you which fits your house after looking at it – that’s the point of carrying both.

What Bloomington Customers Say
"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."
— Jason Norris"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 Salazar"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Todd Ziegler
