Insulation Company in Bloomington, CA
Most Bloomington homes lose conditioned air through attics that were never properly insulated in the first place. Blown in insulation is the fastest, least disruptive way to fix that in the 1940s through 1970s tract houses that line Valley Boulevard and the surrounding streets. Placentia Insulation has served Bloomington since 2018, matching the right material to each home’s framing, roof pitch, and existing insulation. Call (855) 773-6429 for a free estimate.
Why Bloomington Homes Are Different
Bloomington’s housing stock was built for the citrus-packing and railroad workforce, which means single-story stucco over wood frame, low-pitch roofs, and attics that were an afterthought. A surprising number of these homes still have their original insulation, and original in 1950 often meant nothing at all, or a thin layer of fiberglass batts that has since been compressed flat by decades of service work, storage, and rodents. When we open an attic hatch in Bloomington in July, the air that rolls out is routinely 110°F or hotter, because the minimal eave vents on these low roofs don’t move enough air to cool the space.
The desert heat is the obvious problem, but winter nights near freezing are the quiet one. Homes without an adequate thermal boundary at the ceiling plane lose heat fast after sundown, and the furnace cycles all night trying to keep up. It’s a specific kind of discomfort: the thermostat says 72, the floors are cold, and the ceiling feels like it’s radiating cold back down. Bloomington homeowners also contend with the legacy of older building practices. Attics in this area can contain pre-1978 materials, including vermiculite in some cases, which requires careful evaluation before any new insulation goes in. We check for that before we quote, not after.
The other thing we see in Bloomington is the effect of the Santa Ana winds. Fine dust and grit work their way into attic spaces through every gap, settling into whatever insulation is there and reducing its effectiveness. That’s part of why we don’t just top off old insulation. We assess what’s actually up there and what condition it’s in before recommending anything.
Our Main Bloomington Services
The two calls we get most from Bloomington homeowners are for attic upgrades in older tract homes and for spray foam in difficult-to-insulate spaces. Here’s a closer look at each.
Attic Insulation in Bloomington
Attic insulation is the highest-impact upgrade for most Bloomington homes because the attic is where the heat enters in summer and escapes in winter. We frequently find original fiberglass batts that have settled to a third of their rated R-value, or bare ceiling joists with nothing between the living space and the roof deck. The low-pitch roofs common on Valley Boulevard-era homes leave less room to work, so choosing the right material matters. Mineral wool or blown-in cellulose often performs better in tight attics than trying to force full-height batts against roof decking. One contractor handles the assessment, removal if needed, air sealing, and installation. See Attic Insulation in Bloomington for the full breakdown.
Spray Foam Insulation in Bloomington
Spray foam earns its place in Bloomington homes where air movement is the real problem: cantilevered floors, rim joists, and the knee walls in older additions. Open-cell foam is often the right call for interior cavities where sound dampening matters. Closed-cell foam is what we recommend where moisture or structural rigidity is the issue, such as raised foundations that face the seasonal damp of the Inland Empire’s winter. Because we stock Icynene and Demilec products, we choose the chemistry based on the space, not the other way around.

Blown In Insulation in Bloomington
Blown in insulation is the workhorse upgrade for Bloomington’s 1940s through 1970s tract homes. The bare attics, compacted batts, and low-pitch roofs along the old citrus route mean the fastest path to a measured R-value improvement is blowing cellulose or fiberglass across the entire ceiling plane. It fills every odd cavity, settles around existing framing, and does it without pulling down drywall or disrupting the home. Blown In Insulation done correctly transforms an open, heat-soaked attic into a thermal boundary within a single workday.
Cellulose Insulation
Signs you need it
Your existing attic insulation has settled, shows signs of rodent activity, or measures below R-19 when it should be R-38 or higher.
What it costs in Bloomington
Cellulose insulation in Bloomington typically runs from $0.90 to $1.50 per square foot installed, depending on depth and attic access.
How we do it
We prepare the attic by checking for air leaks and any pre-1978 material concerns, then blow GreenFiber cellulose to the target depth using a calibrated hose that gives a consistent, verified R-value across every inch of the attic floor.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic run noticeably hotter than the rest of the house in summer and colder in winter, or your energy bills have crept upward each July and January.
What it costs in Bloomington
Blown in attic insulation in Bloomington generally lands between $1,200 and $2,800 for a typical 1,200-to-1,800-square-foot home, depending on the material and existing conditions.
How we do it
We run the blower hose into the attic through the existing hatch or a dedicated opening, establish the required depth markers for the R-value we’re targeting, and cover the entire ceiling plane in one pass so there are no thin spots.
Blown In Cellulose Insulation
Signs you need it
You want denser coverage than fiberglass provides, with better sound deadening between the attic and living space.
What it costs in Bloomington
Blown in cellulose in Bloomington typically runs $0.90 to $1.50 per square foot, often toward the lower end when covering an open attic floor at standard depth.
How we do it
We arrive with GreenFiber cellulose bales, run them through the blower, and build the depth in layers so the material settles to the rated R-value rather than being blown loose once.
Blown In Fiberglass Insulation
Signs you need it
You want a lighter-weight loose fill option that can be blown over existing fiberglass batts to bring an under-insulated attic up to code without a full removal.
What it costs in Bloomington
Blown in fiberglass in Bloomington typically falls between $0.80 and $1.40 per square foot, and the lighter material makes it a good fit for topping off older batts.
How we do it
We assess whether the existing material is sound enough to build on, then blow fiberglass loose fill across the attic to the depth needed for the specified R-value.
Loose Fill Insulation
Signs you need it
Your attic has odd framing, low clearance, or irregular joist spacing that rigid batts can’t fill without gaps and voids.
What it costs in Bloomington
Loose fill insulation in Bloomington sits in the same range as other blown-in methods, roughly $0.80 to $1.50 per square foot installed, with the exact figure set by depth and material.
How we do it
We blow the material into every corner of the attic, using a wand to direct coverage behind low framing and under roof intersections where batts leave voids and heat pours through.
What Blown In Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Blown in cellulose (per sq ft) | $0.90 – $1.50 |
| Blown in fiberglass (per sq ft) | $0.80 – $1.40 |
| Full attic blow-in for 1,200 – 1,800 sq ft home | $1,200 – $2,800 |
How long does blown in insulation last in a Bloomington attic?
Cellulose and fiberglass loose fill both maintain their rated R-value for decades as long as the attic stays dry and the material isn’t disturbed or compressed. In Bloomington’s dry climate, that’s usually the case. We review your attic’s condition before quoting.
Can blown in insulation be installed over old insulation in Bloomington homes?
Yes, if the existing material is dry, not infested, and not vermiculite. We inspect first. Topping off under-insulated attics with fresh loose fill is often the most cost-effective upgrade we do. Call (855) 773-6429 to schedule an assessment.

What pushes the price up in Bloomington is usually attic access, pre-1978 material that needs careful removal, or an attic with so little clearance that the crew has to work low and slow. We quote upfront and the price doesn’t change unless we find something structural that nobody could see from the hatch.
Neighborhoods We Serve in Bloomington
Bloomington’s 92316 ZIP code covers a tight grid of postwar single-story homes, and we work every street in it. The homes near Valley Boulevard and the old railroad corridor tend to be the oldest, with the least original insulation. The neighborhoods south of Jurupa Avenue and east of Cedar Avenue are a mix of similar-era tracts with slightly larger lots. North of the 10, the homes are newer but still benefit from attic upgrades in the Inland Empire heat. Our crews live close enough that a same-week visit is typical, and urgent jobs can often be scheduled within a day or two.

For most attic and wall insulation upgrades, no permit is required by San Bernardino County. Jobs that involve new construction or altering the building envelope may trigger one. We handle the honest answer on every quote, based on the scope of your specific project.
Only when it’s necessary. If the existing insulation is dry, not infested, and not vermiculite, we can typically blow new loose fill right over it. If it’s compressed, rodent-soiled, or contains pre-1978 material that can’t stay in place, we recommend removal first. We inspect and show you what we find before quoting either way.

What Bloomington Customers Say
"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Gilbert Ramirez"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."
— Veronica Guzman"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
