Insulation Company in Pomona, CA
Blown in insulation is the most common fix we handle in Pomona, where attics in 1940s stucco homes bake under San Gabriel Valley sun and old fiberglass batts have flattened to near zero R-value. The job here usually means pulling out settled, dust-choked material, air-sealing every penetration, and blowing fresh cellulose or fiberglass to a depth that actually holds up against attic temperatures past 130°F. Call us at (866) 393-6041 and we’ll tell you straight what your attic needs and what it’ll cost.
Laguna Hills Insulation has served Pomona since 2014. We work with eight manufacturer brands spanning fiberglass, mineral wool, open- and closed-cell spray foam, and cellulose, which means we’re not pushing one product on every house. The right insulation for your home – not just the easiest one to install.
Why Pomona Homes Are Different
Pomona sits in the hot, dry eastern San Gabriel Valley, where summer temperatures regularly cross 95 to 100°F and attic spaces climb past 130°F. The dominant insulation need here is radiant-heat control and attic and duct protection, not cold-weather heating. Coastal LA homes rarely deal with this kind of sustained solar load. Pomona homes do, every summer, for months.
The housing stock splits in two directions. Downtown and the older east and west tracts run heavily to 1940s through 1970s single-family homes with stucco exteriors, many with little or no original wall insulation. Attic framing is shallow, often 2×4 or 2×6, and what insulation exists is frequently original Kraft-faced batts that have baked flat under decades of valley sun. Post-1980s subdivisions have 2×6 walls and better original builds, but their attics still take the same solar beating. In the older stucco tracts we regularly find attics with no venting at all, which compounds the heat problem and accelerates dry rot in roof sheathing.
What this means practically: a Pomona insulation job is often a full attic cleanout, air-sealing, and a radiant barrier before any new blown insulation goes down. Skipping the cleanout and just blowing new material over the old is a waste of money, and we’ll tell you that before we take the job.
Our Main Pomona Services
Pomona homeowners call us most about two things: re-insulating attics in older homes and air-sealing the gaps that let 130°F attic air leak into living space. Here’s what each involves here.
Attic Insulation in Pomona
Older Pomona attics were built for a different climate reality. We inspect the existing material, check for venting, and measure current R-value before recommending anything. In many downtown-area homes the fix is a full removal of settled or rodent-damaged insulation, air-sealing the top plates and penetrations, and installing new material sized for Pomona’s summer heat load. Get the full breakdown on Attic Insulation in Pomona.
Spray Foam Insulation in Pomona
For Pomona homes with unvented attics, ductwork running through hot attic space, or rooms that never seem to cool evenly, spray foam creates an air barrier and a thermal barrier in a single application. Closed-cell spray foam from Icynene or Demilec is particularly effective against the radiant heat gain that defines Pomona summers. It’s a different performance strategy than blown-in fiberglass or cellulose, and we’ll tell you honestly which one your house needs. Details on Spray Foam Insulation in Pomona.

Blown In Insulation in Pomona
Blown in insulation is the workhorse solution for Pomona’s older housing stock, where 1940s and 1950s stucco homes often have shallow attic framing, no venting, and original batts that have collapsed to nearly nothing under decades of inland heat. The specific fix here is usually a full cleanout followed by dense-packed or loose-fill material that holds its R-value in dry, dusty attic conditions.
We install both cellulose and fiberglass blown insulation, drawing from GreenFiber, Owens Corning, Johns Manville, and Knauf product lines. The choice between them depends on your attic’s depth, venting situation, and moisture profile, not on what we happen to have in the truck.

Blown In Attic Insulation
Signs you need it
Your upstairs rooms run 10 to 15 degrees hotter than the rest of the house, or your attic inspection shows insulation that’s settled below the top of the ceiling joists and no longer forming a continuous layer.
What it costs in Pomona
Blown in attic insulation in Pomona typically runs $1,500 to $2,900 for a standard 1,000-square-foot attic when done as a cleanout-and-reinsulate job, with smaller attics at the lower end.
How we do it
We remove the old material where needed, air-seal top plates, can lights, and wire penetrations, verify or add attic venting, then blow fresh insulation to the target R-value with a machine calibrated for even depth.
Loose Fill Insulation
Signs you need it
Your existing attic insulation has compressed to less than half its original thickness, or you can see bare drywall spots where wind or foot traffic displaced the old material.
What it costs in Pomona
Loose fill insulation over an existing layer, without removal, typically runs $800 to $1,600 in Pomona depending on roof pitch, access, and how much material is needed to reach code-level R-value.
How we do it
We blow loose-fill fiberglass or cellulose across the full attic floor at a consistent density, working around any HVAC equipment and verifying depth with numbered depth markers as we go.
What Blown In Insulation Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Loose fill over existing insulation | $800 – $1,600 |
| Blown in attic insulation (cleanout + new) | $1,500 – $2,900 |
| Blown in cellulose insulation (full job) | $1,200 – $2,400 |
How long does blown in insulation last in Pomona’s heat?
Fiberglass and cellulose both hold up well in dry inland heat, lasting 20 to 30 years when properly installed and kept dry. What fails in Pomona attics is usually the original batt material, not new blown insulation. Call (866) 393-6041 for an attic assessment before deciding.
Is cellulose or fiberglass better for a Pomona attic?
Cellulose packs tighter and reduces airflow through the insulation, which helps in Pomona’s hot attics. Fiberglass is less expensive per R-value and resists settling. We’ll spec one based on your attic’s venting and framing. Call (866) 393-6041 for an exact quote – estimates are free.
