Insulation Company in Pomona, CA
Blown in insulation is the most common call we get from Pomona homeowners, and the reason is straightforward. Most houses here were built between 1940 and 1975, and the original loose-fill or batt insulation in those attics has either settled to a fraction of its former depth or was undersized to begin with. Combine that with summer attic temperatures that routinely hit 140 degrees, and the result is an air conditioner that never cycles off and upstairs rooms that stay hot until midnight.
Aliso Viejo Insulation Co has served Pomona since 2014. We work across all four Pomona ZIP codes – 91766, 91768, 91769, and 91797 – and we carry eight manufacturer brands so the recommendation matches your house, not our inventory. Call (877) 352-4780 for a free estimate.
Why Pomona Homes Are Different
Pomona sits in the inland Pomona Valley, where the marine layer that cools Los Angeles most mornings burns off early and never reaches some neighborhoods at all. Summer highs in the high 90s and low 100s are normal, and the sun beats directly on asphalt-shingle roofs for six to eight hours a day. Attic insulation here is not about keeping heat in. It’s about keeping heat out, and that changes which materials and installation methods make sense.
The housing stock reinforces this. Much of Pomona is 1940s-to-1970s tract and ranch-style construction – wood-framed, vented attics, originally insulated with whatever was cheap at the time. In the older tracts around downtown and north Pomona, we still find original rock wool or loose-fill cellulose that has settled to two or three inches of effective coverage. Some attics still have knob-and-tube wiring running under that old insulation, which means any insulation upgrade needs to be coordinated with electrical work before we blow anything new in. Santa Ana winds, which hit Pomona in the fall, dry out the building envelope further and make air sealing just as important as the insulation itself.
What all this means in practice: Pomona insulation jobs tend to be air-sealing-plus-insulation projects more often than simple top-offs. We plan for that from the start.
Our Main Pomona Services
Pomona homeowners call us most often about two services: attic insulation and spray foam. Both address the same root problem – extreme heat gain – but they go about it differently, and the right choice depends on your attic’s construction, your ductwork location, and your budget.
Attic Insulation in Pomona
For most Pomona tract homes with vented attics, upgrading attic insulation is the highest-impact improvement per dollar spent. We typically remove the old settled material, air-seal the attic floor around top plates and penetrations, and blow in fresh coverage to R-38 or better. The combination of air sealing and new insulation matters more here than in coastal cities because Pomona’s temperature swings are wider. We install fiberglass, cellulose, or mineral wool depending on the attic. See Attic Insulation in Pomona for the full breakdown.
Spray Foam Insulation in Pomona
Spray foam earns its keep in Pomona when the attic is unvented, the ductwork runs through unconditioned space, or the homeowner wants the strongest possible air barrier. We install both open-cell and closed-cell systems from Icynene and Demilec, so we can match the foam chemistry to your roof assembly and moisture profile rather than forcing one product into every situation. Read Spray Foam Insulation in Pomona for the specifics on when foam is worth the higher upfront cost.

Blown In Insulation in Pomona
Blown in insulation is our most-requested service in Pomona because it is the fastest way to fix a settled, underperforming attic in a 1950s or 1960s tract home. Loose-fill cellulose or fiberglass can be blown over existing insulation, into sidewall cavities, or across an open attic floor in a single day, at a lower cost per square foot than spray foam. We are the only insulation contractor most Pomona homeowners need because we install blown-in, attic batts, and spray foam – see our Blown In Insulation page for the full method explanation.
Cellulose Insulation
Signs you need it
Your attic has original loose-fill from the 1960s or 1970s that has settled flat, and your upstairs rooms feel ten degrees hotter than downstairs by mid-afternoon.
What it costs in Pomona
Blown cellulose in Pomona attics typically runs $1.10 to $2.80 per square foot, with most 1,200-square-foot attics landing between $1,300 and $2,900 after removal of old material.
How we do it
We remove or level old insulation, air-seal the attic floor, and blow GreenFiber recycled cellulose to the manufacturer’s specified depth for R-38 in our climate zone.
Blown In Attic Insulation
Signs you need it
Your energy bills from SCE spike every summer while your AC runs nonstop, and you can see the tops of your ceiling joists in the attic.
What it costs in Pomona
Blown attic insulation in Pomona generally falls between $1,400 and $3,200 for a typical ranch home, depending on existing depth and whether old material needs removal first.
How we do it
We set up a containment barrier, run the blower hose through the attic access, and apply material in a consistent, measured layer that reaches the R-value we agreed on before the job started.
Loose Fill Insulation
Signs you need it
Your attic has bare patches, lumpy coverage, or material that crumbles when touched, indicating decades of settlement and moisture exposure.
What it costs in Pomona
Loose fill insulation in Pomona typically costs $0.60 to $2.00 per square foot for fiberglass and $1.10 to $2.80 for cellulose before any removal or air-sealing work.
How we do it
We run a density check on the existing material, remove or top off as needed, and blow a uniform loose-fill layer that meets current DOE recommendations for the Pomona climate zone.
What Blown In Insulation Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Blown fiberglass attic (1,200 sq ft to R-38) | $1,400 – $2,800 |
| Blown cellulose attic (1,200 sq ft to R-38) | $1,600 – $2,900 |
| Old insulation removal and disposal | $0.40 – $1.25 per sq ft |
Does blown-in insulation make a real difference in Pomona’s heat?
Yes. In a Pomona attic that reaches 140 degrees in July, raising ceiling insulation from R-11 settled fiberglass to R-38 blown cellulose keeps significantly more radiant heat out of the living space, reducing cooling load and evening heat bleed. Air sealing added to the job compounds the effect.
Can you blow insulation into walls without removing drywall?
Yes, in many cases. For Pomona ranch homes with empty 2×4 wall cavities, we can drill and fill from the exterior, then patch to match. Call (877) 352-4780 for an attic and wall assessment – the estimate is free.

Two things push prices up in Pomona more than anywhere else we work. The first is old settled insulation that has to be removed before we can blow new material – common in 1940s and 1950s tract homes. The second is knob-and-tube wiring, which stops an insulation job until an electrician signs off. We give you an upfront, line-item price before any work starts, and that number does not change unless you change the scope.

Most attic insulation and blown-in work in Pomona does not require a city permit, but if we find knob-and-tube wiring or unpermitted additions, the scope changes. We handle coordination with any required inspections and will tell you upfront if your project crosses into permit territory.
Yes. We often do single jobs that combine attic insulation, wall drill-and-fill, and crawlspace or rim joist work in Pomona homes, because the older tract stock often needs attention in more than one part of the house. One crew, one schedule, one point of contact for the whole thermal envelope.

— Marcy Anderson"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Sanjay Patel"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
