Insulation Company in Pomona, CA
Most Pomona homes we step into were built between the 1920s and 1950s, and their insulation tells that story: original blown-in settled to a couple of inches, walls with nothing but lath and plaster, and enclosed patios that never got a single batt. Blown in insulation is the most common fix here because it’s the most practical way to retrofit those older cavities without tearing out original plaster. Birch Insulation has served Pomona since 2015, and we carry eight manufacturer lines so the material you get is matched to your home, not to what we happen to stock.

Why Pomona Homes Are Different
Pomona sits at the base of the San Gabriel Mountains in the Pomona Valley, and that position shapes every insulation job here. Summer afternoons push attic temperatures well past 140°F, and Santa Ana wind events drive hot, dry air through every gap in an older envelope. Then winter nights drop cool enough that walls matter for heating, too. The housing stock amplifies the problem: much of the 91766 and 91767 corridors are pre-1960 single-story stucco bungalows and post-war tract homes with original wood lath plaster walls, shallow attics, and DIY-converted garages with zero insulation. We routinely find knob-and-tube-era wall cavities that were never insulated at all. That’s why most Pomona jobs are full-envelope retrofits, not R-value top-offs. A quick attic top-off won’t fix a home where the walls are empty and the converted garage is unconditioned. The right approach here is an assessment first, then material that fits each cavity.
Our Main Pomona Services
Pomona homeowners call us most about two services: attic insulation and spray foam. Both solve real problems in this climate, but they work differently and suit different houses. Here’s what each involves locally.
Attic Insulation in Pomona
Attics here run brutal in summer, and a shallow 1950s attic with settled fiberglass is doing almost nothing to keep that heat out of your living space. We assess what’s up there, remove or top off what’s failing, air-seal the ceiling plane where possible, and bring the attic to a level that actually changes your indoor temperature. For older Pomona bungalows and post-war tract homes, this is usually the single highest-impact job we do. Full details are on our Attic Insulation in Pomona page.
Spray Foam Insulation in Pomona
Spray foam earns its keep in Pomona’s converted garages, enclosed patios, and any room where a previous owner skipped insulation entirely. Closed-cell foam air-seals and insulates in one pass, which matters when Santa Ana winds are driving dust and heat through open wall cavities. We install both Icynene and Demilec products, so open-cell and closed-cell options are on the table. Your home’s construction decides which one makes sense.

Blown In Insulation in Pomona
Blown in insulation is the workhorse retrofit for Pomona’s older homes. The 1920s bungalows and 1950s tract houses off the 91766 and 91767 corridors frequently have original attic blown-in that has settled to a couple of inches, or walls that never had insulation at all. Blown-in material flows into those irregular, shallow cavities in a way batts can’t, which is exactly what these houses need. We’re a material-agnostic installer, so whether the job calls for Blown In Insulation with GreenFiber cellulose or Johns Manville fiberglass, we match the product to your home and your budget.
Cellulose Insulation
Signs you need it
Your attic has old, settled insulation sitting a couple of inches deep, or you want a denser, recycled-content material that fills wall cavities well.
What it costs in Pomona
Cellulose attic insulation in Pomona typically runs $1,450 to $2,900 depending on square footage and how much removal the existing material needs.
How we do it
We prep the attic, seal penetrations where needed, and blow GreenFiber cellulose to the specified depth and density, checking coverage as we go.

Blown-in attic work in Pomona averages $1,500 to $3,000, with older attics on the higher end when we’re pulling out decades of settled material first.

We remove or top off what’s there, blow the new material to a consistent depth across the full attic floor, and keep baffles clear for ventilation.

Signs you need it
Your attic has thin or patchy fiberglass and you want a fast, cost-effective top-off that improves R-value without major disruption.
What it costs in Pomona
Blown-in fiberglass in Pomona typically runs $1,200 to $2,400 depending on attic size and target depth.
How we do it

Loose Fill Insulation
Signs you need it
Your attic has settled material, bare spots, or a previous owner’s DIY job that never reached the depth the house actually needs.
What it costs in Pomona
Loose fill insulation in Pomona runs $1,200 to $2,500 for a standard attic, depending on material type and existing conditions.
How we do it
We assess what’s there, recommend the right loose fill material, and blow it to an even depth that actually changes how the house holds temperature.

What Pomona 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."
— Neil Hayes"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Allen Kim"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Katie Whitaker
