Insulation Company in Bloomington, CA
Blown in insulation solves most of what Bloomington throws at a house. We’re filling attics across 92316 with loose fill and dense packed cellulose because mid-century stucco homes bake in the inland sun, and original fiberglass batts from the 1950s and ’60s have long since slumped flat. If your cooling bill climbs every July and the upstairs still feels hot at 9 p.m., the answer is usually an attic that’s lost its thermal boundary. Call Fontana Insulation at (866) 271-1602 and we’ll tell you what’s actually up there.
Why Bloomington Homes Are Different
Bloomington sits in a hot, semi-arid pocket of San Bernardino County where summer temperatures regularly push past 100°F. The housing stock is mostly single-story stucco from the 1940s through 1970s, built along the old Route 66 corridor with low-pitch roofs and shallow attic spaces. Shade trees are scarce on the flat inland lots, so the roof takes direct sun from mid-morning until sunset. We routinely measure attic temperatures of 140°F or more during July and August. That heat radiates down through the ceiling all evening, long after the outside air cools.
The insulation in these homes was never designed for that reality. Many Bloomington houses still have original kraft-faced fiberglass batts that have compressed, baked, and lost whatever R-value they once had. Manufactured and mobile homes in the older unincorporated pockets often have even thinner ceiling cavities. The job here isn’t winter warmth. It’s killing attic heat gain and stopping radiant transfer through unshaded roofs and west-facing walls. We approach every Bloomington attic with that specific problem in mind.
Our Main Bloomington Services
Bloomington homeowners call us most often about two projects: adding insulation to attics that were built decades ago, and using spray foam where air leaks and tight spaces demand something more than a blanket material.
Attic Insulation in Bloomington
Most Bloomington attics were insulated once, perhaps forty or fifty years ago, and never touched again. The batts have fallen away from the eaves, the loose fill has settled, and gaps around plumbing vents and electrical boxes let hot air pour straight into the living space. We remove or top off what’s there, air-seal the ceiling plane, and bring the attic up to a level that actually makes a difference in July. The low-pitch roofs here leave limited working room, so our crews are used to navigating shallow cavities and tight access hatches. Learn more on our full page for Attic Insulation in Bloomington.

Spray Foam Insulation in Bloomington
For attics that can’t be easily vented, additions with exposed rafter bays, or walls where air sealing matters as much as R-value, spray foam is often the right call. It forms a continuous thermal and air barrier in one application, which helps when every degree of attic heat is fighting your air conditioner. We install open- and closed-cell foam, matched to the cavity and the moisture conditions of the specific house. Details are on the Spray Foam Insulation in Bloomington page.

Blown In Insulation in Bloomington
Blown in insulation is the most common fix we do in Bloomington, and it’s usually the most cost-effective one. Loose fill fills every irregular cavity, settles around wiring and framing, and can be installed without tearing out ceilings or walls. In homes where the original batt insulation has baked flat over decades of Inland Empire summers, blowing in a fresh layer over the top restores the attic’s thermal break quickly. Most Bloomington attics take a crew half a day, and the house feels different the very next afternoon.
We offer fiberglass and cellulose loose fill, including GreenFiber cellulose for homeowners who want recycled-content material. Both work well here; cellulose tends to pack denser and resist air movement, while fiberglass is lighter and sometimes preferable in older ceiling assemblies. If you’re not sure which one fits your attic, call us and we’ll walk through the trade-offs honestly. You can also read more on our main Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the tops of the ceiling joists, or you can see bare drywall in places when you look up through the access hatch.
What it costs in Bloomington
Blown cellulose for a typical Bloomington attic runs $1.50 to $3.50 per square foot installed, depending on depth and prep work.
How we do it
We air-seal the attic floor penetrations, mark target depth in every bay, then blow in cellulose to the spec your house needs.
Blown In Attic Insulation
Signs you need it
Rooms near the center of the house stay hot after sundown, or your air conditioner runs nonstop from mid-afternoon until midnight.
What it costs in Bloomington
Blown in attic insulation in Bloomington typically costs $1.00 to $2.50 per square foot installed, with a full attic often landing between $1,200 and $2,800.
How we do it
We remove or assess the existing material, seal ceiling penetrations, and blow loose fill to the agreed depth, then verify coverage with a depth gauge.
What Blown In Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Cellulose blown in per square foot | $1.50 – $3.50 |
| Fiberglass loose fill per square foot | $1.00 – $2.50 |
| Full attic (1,200 – 1,800 sq ft) | $1,200 – $3,800 |
Depth is the main driver here. If your attic currently has R-11 or bare drywall, you’ll pay more than a top-off job over existing R-19. We quote the exact depth and material type before any work starts.
Does blown in insulation actually help in Bloomington heat?
Yes. Loose fill works by slowing radiant heat transfer from the attic into the living space. A properly insulated Bloomington attic stays significantly cooler in the evening, which reduces how hard the air conditioner has to work during the hottest hours.
Can you blow insulation into my existing attic without removing the old batts?
Usually yes. If the old material is dry and not moldy, we can blow loose fill directly over it. If it’s compressed flat, that’s fine too; the new layer carries the R-value either way. Call (866) 271-1602 for a specific assessment.
Brands We Service in Bloomington
We stock and install fiberglass from Johns Manville and Knauf, mineral wool from Rockwool, and cellulose from GreenFiber. Blown in jobs here most often use fiberglass or cellulose, while Rockwool shows up in walls where fire resistance or sound dampening matters. Most materials are in our local inventory, so a Bloomington attic rarely waits more than a day or two for product. See what we carry on our brands page.

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."
— Sarah Fletcher"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."
— Holly Mercer"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Nadia Aziz
