Insulation Company in Montebello, CA
Blown in insulation is the most common retrofit we install in Montebello, and for good reason: most of the housing stock here went up between the 1940s and 1960s with little to no thermal protection. Those stucco tract homes and low-rise apartment buildings soak up summer heat through the attic and radiate it back down long after sunset. At Fontana Insulation, we carry eight brands across fiberglass, mineral wool, spray foam, and cellulose so the material we recommend is the one that actually fits your Montebello home’s construction, not whatever happens to be on the truck.

Why Montebello Homes Are Different
Walk down almost any residential street in the 90640 ZIP and you’ll see the same pattern: mid-century stucco boxes on compact lots, many with original framing and attic spaces that were never meant to hold insulation. The city sits in the mild LA basin, frost-free and warm, which means Montebello’s insulation problem isn’t freezing pipes or deep-winter cold. It’s attic heat gain. In July and August, an uninsulated attic can climb past 140 degrees, and that heat pushes down into living spaces for hours after the sun drops. The real technical challenge we run into on Montebello jobs is venting. A lot of these older homes have soffit vents that were blocked when stucco was patched, or attic openings too small to move air properly. That’s before you even get to the enclosed patios and converted garages common on these lots, which create dead-air pockets and complicate the thermal boundary. Older knob-and-tube-era wiring in some of these attics also means the insulation has to be installed around electrical that newer homes don’t have.
Our Main Montebello Services
Most Montebello homeowners call us about one of two things: either their attic is baking the upstairs rooms, or they have walls and rim joists that leak air. Both are covered by the two services below.
Attic Insulation in Montebello
Attic work in Montebello almost always means retrofitting a mid-century home that has fiberglass batts compressed to nothing or no insulation at all. We check venting first, because adding insulation without fixing blocked soffit vents turns an attic into an oven. From there we blow loose fill or lay batts to the R-value your roof assembly needs, working around the older wiring and odd framing these homes have in abundance. Attic Insulation in Montebello covers the full scope.
Spray Foam Insulation in Montebello
For the enclosed patios, converted garages, and stubborn rim-joist leaks we see across Montebello’s older lot stock, spray foam is often the only material that seals and insulates in one pass. Closed-cell foam adds structure and blocks air movement; open-cell handles sound and odd-shaped cavities. We’re an authorized installer for Icynene and Demilec, two of the most performance-tested foam lines in North America. Spray Foam Insulation in Montebello has the details.

Blown In Insulation in Montebello
Blown in insulation is the workhorse retrofit for Montebello’s 1940s-1960s tract homes because it fills the irregular cavities, shallow attics, and awkward framing these houses are full of. Loose fill settles into the nooks that rigid batts can’t touch, and it installs fast enough that we can usually complete a standard Montebello attic in a single day without tearing out drywall. Whether we’re using cellulose or fiberglass, the material gets chosen for your specific attic, not from habit. Learn more about the method on our Blown In Insulation hub.
Cellulose Insulation
Signs you need it
Your attic has settled old insulation, gaps around framing, or you want a denser recycled-content option that blocks airflow better than loose fiberglass.
What it costs in Montebello
Blown-in cellulose for a typical Montebello attic runs $1.70 – $3.10 per square foot installed.
How we do it
We air-seal bypasses, verify the attic vents are clear, then dense-pack or loose-blow GreenFiber cellulose to the target R-value with a calibrated machine.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic get noticeably hotter than the rest of the house by mid-afternoon, or you can see the ceiling joists through a thin layer of old material.
What it costs in Montebello
Full attic blow-in for a Montebello home typically lands between $2,200 and $6,200 depending on the square footage and current depth.
How we do it
We prep the attic, confirm every vent is functioning, then blow loose fill evenly to the depth your R-value target requires, keeping the material off the eave vents.
Blown In Cellulose Insulation
Signs you need it
You want a denser recycled-content product that reduces air movement through walls or attic floors better than standard fiberglass, especially in older Montebello homes with leaky framing.
What it costs in Montebello
Blown-in cellulose runs $1.70 – $3.10 per square foot in Montebello.
How we do it
We run a hose to the attic or wall cavity and dense-pack GreenFiber cellulose, which fills voids and adds a modest air-sealing effect as it compacts into place.
Blown In Fiberglass Insulation
Signs you need it
You want a lightweight loose fill that’s fast to install and keeps dust down, while still hitting the R-value your attic needs for Montebello summers.
What it costs in Montebello
Blown fiberglass in Montebello runs $1.40 – $2.80 per square foot for attic applications.
How we do it
We blow Johns Manville or Knauf loose fiberglass to the specified depth, using marked depth gauges so the R-value is consistent across the whole attic floor.
What Blown In Insulation Costs in Montebello
| Item | Typical range in Montebello |
|---|---|
| Blown fiberglass attic | $1.40 – $2.80 per sq ft |
| Blown cellulose attic | $1.70 – $3.10 per sq ft |
| Full attic blow-in (labor + material) | $2,200 – $6,200 |
Is blown in insulation worth it in Montebello’s climate?
Yes, because attic heat gain is the dominant problem here. Blown-in material cuts the heat that radiates down into living spaces, and the job typically pays for itself through reduced summer air-conditioning use.
Can you blow insulation into existing walls in Montebello?
In many cases, yes. Dense-pack cellulose works through small drilled holes, which suits the stucco exteriors common in Montebello. We’ll assess the wall cavities and wiring first. Call (866) 271-1602 for a free estimate.

What Montebello Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Michelle Bennett"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
