Insulation Company in Pomona, CA
Blown in insulation solves the most frustrating problem in Pomona homes: attics that turn into ovens by noon and bedrooms that never cool down even after the sun sets. Old Pomona bungalows from the 1920s through 1950s rarely have more than a few inches of settled, crumbling material up top, and many have none at all. We’re Brea Insulation, a dedicated insulation contractor, and we’ve worked in Pomona long enough to know exactly what these houses need. Call (866) 858-4033 for a free estimate on blown in insulation that actually holds up to San Gabriel Valley summers.
Why Pomona Homes Are Different
Pomona’s housing stock splits sharply between pre-war bungalows and post-war ranch tracts in the 91766 and 91767 ZIP codes, and newer subdivisions out toward 91768. The older homes share a common DNA: plaster-and-lath or early drywall walls, shallow low-pitch attics, and insulation that was either never installed or has compacted to near zero over 60 or 70 years. The dominant concern here is heat, not cold. Summer highs regularly climb into the 90s and 100s, and that intense inland sun turns an uninsulated attic into a heat reservoir that radiates down through ceilings all afternoon and evening. Winters are mild, so the payoff on insulation in Pomona comes almost entirely from summer comfort and air-conditioning load reduction. On many old Pomona bungalows, the attic is so cramped that standard blown-in depth won’t fit without air-sealing and sometimes re-routing knob-and-tube wiring first. That’s the reality of the work here, and it’s why a specialist who has seen these attics matters.
Our Main Pomona Services
Pomona homeowners call us most often about two services: attic insulation and spray foam insulation. Each has its own dedicated Pomona page below because the scope of work differs enough to deserve a full explanation.
Attic Insulation in Pomona
Attic insulation is the biggest energy win for most Pomona homes, especially the older single-story stock where heat pours down from the roof cavity all summer. On 1920s and 1930s bungalows we often find rafter bays too shallow for standard coverage and old wiring buried in what little fill exists. The job usually starts with air-sealing bypasses around ceiling fixtures and top plates, then bringing the attic up to current Title 24 depth. We carry eight brands so the material matches the house, not our inventory. For a full breakdown of costs and methods specific to Pomona attics, see our Attic Insulation in Pomona page.
Spray Foam Insulation in Pomona
Spray foam does two jobs at once in Pomona: it insulates and it air-seals, which matters when you’re fighting 100-degree attic temperatures. In older Pomona homes with irregular cavities and open framing, closed-cell foam from Icynene or Demilec creates a thermal break that batt or blown-in material simply cannot match. It’s also the right call for hard-to-reach rim joists and crawlspace lids in the 91768 tract homes. The product costs more up front, but the air-sealing benefit pays back faster in this climate. For a complete discussion of spray foam options and what they cost in Pomona, read our Spray Foam Insulation in Pomona page.

Blown In Insulation in Pomona
Blown in insulation is the most common retrofit we perform in Pomona because it’s the practical answer for attics that were never properly insulated. Loose fill material can be blown into tight rafter bays and around existing framing without tearing out walls or ceilings, which matters on older plaster-and-lath homes where demolition gets expensive fast. In Pomona’s heat, the goal is usually reaching the Title 24 attic depth so the ceiling stops radiating heat into living spaces by mid-afternoon. This is the core of our work here, and you can read more about it on our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Rooms directly under the attic are 10 to 15 degrees warmer than the rest of the house by 3 p.m., and your AC runs nonstop from June through September.
What it costs in Pomona
Blown-in cellulose in Pomona typically ranges from $1.00 to $1.80 per square foot of attic area depending on depth and prep work.
How we do it
We air-seal the attic floor, prep the space, then blow GreenFiber recycled cellulose to the specified depth using calibrated equipment for even coverage.
Blown In Attic Insulation
Signs you need it
Your attic has less than 6 inches of existing insulation, or the material up there is settled, dusty, and matted down from decades of heat and foot traffic.
What it costs in Pomona
A typical Pomona attic top-up or full blown-in job runs $1.00 to $2.20 per square foot depending on whether we’re adding to existing material or starting clean.
How we do it
We inspect and air-seal first, then blow loose fill to R-38 or higher across the entire attic floor, keeping soffit vents clear for airflow.
Blown In Fiberglass Insulation
Signs you need it
You want a non-cellulose option that will not settle as much over time, and your attic is deep enough to take a full fiberglass depth.
What it costs in Pomona
Blown-in fiberglass in Pomona runs $1.20 to $2.50 per square foot for attic coverage, with the higher end reflecting deeper R-value targets.
How we do it
We blow Owens Corning fiberglass loose fill to the specified R-value, using depth markers throughout the attic so coverage is consistent and verifiable.
What Blown In Insulation Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Blown-in cellulose (attic) | $1.00 – $1.80 per sq ft |
| Blown-in fiberglass (attic) | $1.20 – $2.50 per sq ft |
| Attic air-sealing before blown-in | $250 – $800 depending on attic size |
How long does blown in insulation last in Pomona?
Cellulose typically holds its R-value for 20 to 30 years, but Pomona’s extreme attic heat can accelerate settling. Fiberglass is less prone to compaction. Call (866) 858-4033 and we’ll inspect what’s up there now.
Can blown in insulation be added over old insulation in Pomona?
Yes, in most Pomona homes we blow new material directly over the old layer after checking for moisture, mold, and wiring issues. The new depth adds R-value on top of what remains. Call (866) 858-4033 for an attic assessment.
