Insulation Company in Pomona, CA
Blown in insulation solves the two biggest problems Pomona homeowners face: attics that hit 140°F in August and walls that were never insulated when the house was built. Our crews work in 91766 bungalows with knob-and-tube wiring and in 91768 tract homes with thin 1960s batt insulation, and the approach differs for each. If you’re done guessing why the upstairs never cools down, call North Tustin Insulation at (877) 265-5712 for a straight answer and a free estimate.
Why Pomona Homes Are Different
Pomona sits at the base of the San Gabriel Valley where summer heat builds for months. Unlike coastal LA, inland temperatures here run 10 to 20 degrees hotter, which means attic spaces routinely exceed 140°F and radiant heat gain becomes the dominant comfort problem. That heat loads the attic, pushes into the living space through unsealed penetrations, and forces air conditioners to run longer than they should.
The housing stock splits sharply. Around downtown in 91766, you’ll find 1900s to 1930s craftsman bungalows and two-story Victorians with balloon-frame walls, original plaster, and often zero insulation anywhere. These homes were built before insulation was standard, and many still have active knob-and-tube wiring in the attic. Retrofitting them requires careful clearance around live old wiring, a challenge newer coastal developments never present.
East and north in 91767 and 91768, the story shifts to 1950s and 1960s single-story tract homes. Many still carry their original R-11 attic batts, which is well below what Pomona’s climate demands. Some of these homes also have flat or low-slope roofs, which changes how we access the attic cavity. Title 24 cool-roof and duct requirements factor into upgrades here, especially when adding air-sealing or radiant-barrier work alongside new insulation.
Our Main Pomona Services
Most Pomona homeowners call us about two services: attic insulation and spray foam. Both solve different problems depending on your home’s age, roof type, and how you use the space.
Attic Insulation in Pomona
Attic work in Pomona almost always starts with an inspection of what’s already up there, because the answer varies by neighborhood. A 1920s bungalow in 91766 might have nothing but bare joists and old wiring, while a 1960s tract home in 91768 likely has compacted R-11 batts that stopped performing years ago. We air-seal the attic floor penetrations first, then bring the insulation up to what Pomona’s heat load actually requires. This is the single highest-impact upgrade for most homes here. Learn more about Attic Insulation in Pomona.
Spray Foam Insulation in Pomona
Spray foam earns its keep in Pomona homes with flat or low-slope roofs, unvented attic designs, or homeowners trying to turn a punishing attic into usable storage. We install both Icynene and Demilec systems, which means open-cell and closed-cell options are on the table depending on your roofline and moisture exposure. Closed-cell foam also adds structural racking strength, a real consideration for older Pomona homes. See what’s involved on Spray Foam Insulation in Pomona.

Blown In Insulation in Pomona
Blown in insulation is the fastest, least disruptive way to bring a Pomona attic up to modern R-value. In homes built before 1980, the attic is usually the single largest source of heat gain in summer and heat loss on winter nights. Blowing in cellulose or fiberglass over existing batts and into wall cavities can cut that heat transfer dramatically, and it’s the method we recommend most often for retrofit work. See our full Blown In Insulation service details.
Cellulose Insulation
Signs you need it
Rooms that never match the thermostat setting, high summer electric bills, and attic insulation that looks settled or sparse when you peek in.
What it costs in Pomona
Blown-in cellulose in Pomona typically ranges from $1.50 to $3.50 per square foot installed, depending on depth and prep work.
How we do it
We air-seal penetrations first, then blow GreenFiber recycled cellulose to the target depth across the entire attic floor.
Blown In Attic Insulation
Signs you need it
Upstairs rooms that are 10 degrees hotter than downstairs, or an attic with batts that have compressed to half their original thickness.
What it costs in Pomona
Blown-in attic insulation in Pomona generally costs $1,500 to $3,600 for an average single-story home, depending on attic size and access.
How we do it
We remove or supplement existing material, air-seal the attic floor, and blow insulation evenly to the R-value Pomona’s climate requires.
Loose Fill Insulation
Signs you need it
Gaps and bare patches in your current attic insulation, or drafty rooms that suggest air moving through uninsulated cavities.
What it costs in Pomona
Loose fill insulation in Pomona typically runs $0.90 to $2.60 per square foot for the material and installation combined.
How we do it
We blow loose fill into irregular cavities, around obstacles, and across attic floors to eliminate voids that batts can’t fill.
What Blown In Insulation Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Blown-in attic insulation (average single-story home) | $1,500 – $3,600 |
| Blown-in cellulose (per sq ft installed) | $1.50 – $3.50 |
| Loose fill insulation (per sq ft installed) | $0.90 – $2.60 |
Attic size, access difficulty, and whether we need to remove old material all move the final number. For a firm quote on your Pomona home, call (877) 265-5712.
Is blown in insulation worth it in Pomona’s heat?
Yes. Pomona attics hit 140°F or more in summer, and blown-in insulation stops that heat before it reaches your living space. The energy savings typically pay for the job within a few years.
Can you blow insulation into existing walls in Pomona?
We can, and it’s a common retrofit in older Pomona homes with empty exterior wall cavities. In pre-war bungalows with balloon frames, we drill access holes and blow material into the stud bays from outside.
Brands We Service in Pomona
We stock and install across eight insulation brands, including Owens Corning, Icynene, Demilec, and GreenFiber. That means we match the material to your Pomona home’s needs rather than pushing whatever product happens to be on the truck. See our brands for the full lineup.

What Pomona Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Ryan Rhodes"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Bethany Ziegler"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."
