Insulation Company in Citrus, CA
Blown-in insulation is the most common retrofit we handle in Citrus, and for good reason: most homes here were built between the 1950s and 1970s with thin original insulation that has flattened, settled, or simply disintegrated over decades of San Gabriel Valley heat. At East Los Angeles Insulation Co, we install blown-in fiberglass, cellulose, and mineral wool in attics and walls throughout the 91702 ZIP code, matching the material to each home’s specific construction. Whether you need an attic topped off before summer or wall cavities filled in an older stucco home, call us at (866) 566-0304 for a straight answer and a free estimate.
Why Citrus Homes Are Different
Citrus sits in the San Gabriel Valley foothills just south of the Angeles National Forest, and the heat here is not the same as what you get down in the flat parts of the valley. Summer temperatures climb hard, and Santa Ana wind events push hot, dry air across the foothills for days at a time. Homes in this part of Citrus were mostly built as mid-century ranch and tract houses, and many of them left the factory with nothing more than a thin layer of fiberglass in the attic, if that. Single-pane windows were standard. Wall insulation was often skipped entirely in the stucco-clad single-wall builds of that era.
What that means in practice is simple: the defining insulation problem in Citrus is aging, under-insulated existing homes, not new construction. Our technicians regularly find attic insulation compressed to a fraction of its original depth, heat-cycled into a mat that does almost nothing to slow heat gain. In summer, attic temperatures in the older foothill tracts spike well past typical valley readings. The habit we have developed locally is to air-seal before adding R-value, because adding fresh insulation on top of leaky can lights, unsealed top plates, and open chase ways is wasted effort. The order matters: seal the attic floor, then blow in the right depth.
Mild winters mean freeze protection is rarely the concern here. The work is about keeping heat out, reducing air-conditioner runtime, and making rooms stay comfortable through the long hot season. That changes how we think about material choice and attic ventilation.
Our Main Citrus Services
Most Citrus homeowners call us about one of two things: bringing an old attic up to current code levels of insulation, or sealing and insulating hard-to-treat areas with spray foam. Here is how each one works in this area.
Attic Insulation in Citrus
Attics are where the majority of residential heat gain happens in the foothills, and in Citrus the older ranch homes usually have attic access that makes this the first and most cost-effective upgrade. We inspect what is already up there, check for air leakage, and then recommend the right material and depth for the home’s age and construction. Blown-in fiberglass, cellulose, or mineral wool all have a place depending on the situation. This is our specialty, not an afterthought. Attic Insulation in Citrus

Spray Foam Insulation in Citrus
Spray foam earns its keep in the parts of Citrus where heat finds gaps that batts and blown-in cannot reach: rim joists, cantilevered floors, crawlspace ceilings, and the underside of roofs. In stucco single-wall construction, closed-cell foam is often the only practical way to add a meaningful thermal and air barrier without tearing into walls. We install open-cell and closed-cell foam from Demilec and Icynene, and our crew is trained specifically for foam work, which is a different discipline than general insulation.

Blown In Insulation in Citrus
Blown-in insulation is the workhorse retrofit for Citrus homes. In a 1950s or 1960s ranch house where the original attic insulation has settled to two inches of dust, blowing in fresh material over the top is the fastest, cleanest way to restore true thermal performance. For stucco single-wall construction, blowing insulation into closed wall cavities is often the only practical option that does not involve opening the walls. We install blown-in fiberglass, cellulose, and mineral wool, and the right choice depends on the home’s construction and the homeowner’s priorities.

Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the ceiling joists, or you can see bare patches where old material has shifted.
What it costs in Citrus
Cellulose insulation in Citrus typically runs $1.20 to $2.30 per square foot installed, depending on depth and access.
How we do it
We air-seal the attic floor, then blow GreenFiber cellulose to the specified depth using a calibrated machine so the R-value is uniform.
Blown In Attic Insulation
Signs you need it
Upstairs rooms run noticeably hotter than the rest of the house in summer, or your AC runs constantly during heat spikes.
What it costs in Citrus
Blown-in attic insulation in Citrus typically falls between $1.50 and $4.00 per square foot installed, with depth and existing insulation driving the range.
How we do it
We remove or level existing material where needed, seal air leaks at the attic floor, install baffles at the eaves, and blow fiberglass or cellulose to code depth.
Blown In Cellulose Insulation
Signs you need it
You want a higher recycled content and better air-blocking performance than fiberglass in your attic or existing wall cavities.
What it costs in Citrus
Blown-in cellulose in Citrus runs $1.20 to $2.30 per square foot, including dense-pack wall applications where access allows.
How we do it
For attics we blow loose-fill GreenFiber to the required depth; for walls we dense-pack the material under pressure to resist settling.
Blown In Fiberglass Insulation
Signs you need it
You want a moisture-resistant, non-combustible attic insulation with stable R-value that will not settle over time.
What it costs in Citrus
Blown-in fiberglass in Citrus typically costs $1.20 to $2.50 per square foot installed, depending on target R-value.
How we do it
We blow Owens Corning or Johns Manville loose-fill fiberglass to the specified depth, using a calibrated machine and checking depth markers throughout the attic.
Loose Fill Insulation
Signs you need it
You have an open attic floor with irregular joist spacing, obstructions, or low-clearance areas where batts would not fit properly.
What it costs in Citrus
Loose fill insulation in Citrus runs $1.20 to $2.50 per square foot installed, depending on material and depth.
How we do it
We blow loose-fill material into the attic using a hose and calibrated machine, working around framing and mechanicals to achieve continuous coverage.
What Blown In Insulation Costs in Citrus
| Item | Typical range in Citrus |
|---|---|
| Blown-in attic insulation | $1.50 – $4.00 per sq ft |
| Blown-in cellulose | $1.20 – $2.30 per sq ft |
| Blown-in fiberglass | $1.20 – $2.50 per sq ft |
Two things push blown-in cost up in Citrus: the condition of what is already in the attic, and whether air-sealing needs to happen first. Homes with original 1950s insulation that has compacted into a dense mat often require removal before new material goes in. We quote a firm price up front and do not add charges for discovery once the work starts.
How long does blown-in insulation last in Citrus?
Blown-in fiberglass holds its R-value indefinitely if it stays dry. Cellulose settles about 10 to 15 percent in the first year, then stabilizes. In Citrus, the bigger issue is heat cycling, not age. Call us at (866) 566-0304 if you want us to inspect your attic depth.
Can you blow insulation into existing walls in Citrus?
Yes, if the walls are accessible from the outside or attic. Many Citrus stucco homes have cavities that are good candidates for dense-pack cellulose. We can tell you whether your specific house will work after looking at the construction. Call (866) 566-0304 for an assessment.
Brands We Service in Citrus
We stock and install fiberglass from Owens Corning and Johns Manville, recycled-content cellulose from GreenFiber, and spray foam from Demilec. That means we are not pushing one product onto every job. Most common materials are on our trucks, so we do not lose days waiting on supply runs. See our brands for the full line.

What Citrus 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 Walsh"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
- Rosa Martinez"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
