Insulation Company in Pomona, CA
Blown in insulation solves the single biggest comfort problem Pomona homeowners face: houses built between 1940 and 1965 with almost nothing in the walls and attics. Those post-war stucco-and-wood-frame homes in 91766 and 91767 were never designed for the kind of heat Pomona gets now, where summer afternoons routinely push attic temperatures past 140°F. We install loose-fill cellulose and fiberglass in attics, walls, and tight crawlspaces across Pomona, and we only do insulation. That means we diagnose the actual problem, match the material to the house, and don’t try to sell you a roof repair on the way out. Call (877) 680-3557 for a free estimate.
Why Pomona Homes Are Different
Pomona’s housing stock tells the story. The older core around 91766 and 91767 is dense with 1940s-to-1960s tract homes: stucco exterior, wood frame, vented attic, and original insulation that is either a few thin inches of settled mineral wool or nothing at all. Those homes have 2×4 ceiling joists and unconditioned attic spaces where the HVAC ducts sit and bake all afternoon. The east-side developments in 91768 are newer and built tighter, but even those benefit from attic upgrades because Pomona’s climate punishes any gap in the thermal envelope. Hot-summer Mediterranean means days over 95°F are normal from June through October, and the afternoon sun hits flat-pitched roofs hard. Winters are mild, so heating insulation is secondary here. What matters in Pomona is keeping heat out, and the attic is where it enters first. Rental and multifamily conversions in the older neighborhoods are a growing part of what we do, because bringing those units up to current Title 24 energy standards almost always means replacing attic and crawlspace insulation that has been there since the Eisenhower administration.
Our Main Pomona Services
Two services account for most of the calls we get from Pomona homeowners: attic insulation retrofits for older homes, and spray foam for walls and tight spaces where air sealing matters most.
Attic Insulation in Pomona
In Pomona’s older tract homes, the original attic insulation is often thin, settled, or missing entirely. We regularly open attic hatches in 91766 and find nothing but a few inches of 1960s mineral wool lying between exposed 2×4 joists, while the ducts and air handler sit in 140°F unconditioned air. That layout makes attic insulation and duct sealing the highest-impact upgrade you can make to a Pomona home. We remove or top up what’s there, seal the bypasses around wire penetrations and ceiling fixtures, and bring the assembly up to the R-value your specific roof pitch and venting arrangement can handle. Get the full picture on Attic Insulation in Pomona.

Spray Foam Insulation in Pomona
Some Pomona homes need more than blown-in material can deliver. Wall cavities in the older stucco houses usually have zero insulation, and closed-cell spray foam is the only retrofit that insulates and air-seals those narrow 2×4 bays in one pass. Open-cell foam works well for attics and interior walls where you want sound control along with thermal performance. Because we install both Icynene and Demilec products, we’re not steering you toward one brand – we match the foam chemistry to your wall assembly, your roof design, and your budget.

Blown In Insulation in Pomona

Blown in insulation is the most practical retrofit for the majority of Pomona homes. In the older core around 91766 and 91767, walls are usually uninsulated, the attic has at best a few settled inches of aged mineral wool, and the ducts run through unconditioned spaces that hit 140°F every summer afternoon. Loose-fill insulation fills those irregular cavities and settles into place around wiring, plumbing, and framing without tearing out drywall. That’s why it’s the service we recommend most often for Pomona’s post-war tract homes: it’s the fastest path from “thin or nothing” to a properly insulated envelope. If you want more detail on the material options and the installation process, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic has settled material that no longer reaches the top of the joists, or your walls were never insulated at all and every summer afternoon the west-facing rooms turn into ovens.
What it costs in Pomona
Blown-in cellulose typically runs $0.90 to $1.70 per square foot in Pomona, depending on the depth required and how much old material needs to be removed first.
How we do it
We run a hose from our truck to the attic or wall cavity, feed GreenFiber cellulose through a blower at controlled density, and verify the installed depth against the R-value target.
Blown In Attic Insulation
Signs you need it
Your attic has no insulation beyond scattered remnants, or the existing layer is so thin that heat radiates straight down through the ceiling every afternoon.
What it costs in Pomona
Attic-only blown-in insulation in Pomona usually falls between $1,200 and $2,600 for a typical 1,200-to-1,600-square-foot home, including prep and cleanup.
How we do it
We air-seal penetrations first, install baffles where the attic vents meet the eaves, then blow loose-fill material evenly across the entire attic floor to the specified depth.
What Blown In Insulation Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Blown-in insulation (materials and labor) | $0.90 – $1.70 per sq ft |
| Attic-only blown-in retrofit | $1,200 – $2,600 per project |
| Existing insulation removal (if needed) | $0.25 – $0.50 per sq ft |
How long does blown in insulation last in Pomona?
Cellulose and fiberglass loose-fill both last 20 to 30 years before performance drops noticeably, though Pomona’s extreme attic heat can settle material faster. An attic inspection every few years tells you whether topping up is worthwhile. Call (877) 680-3557 if you want us to check yours.
Can you blow insulation into walls without removing drywall?
Yes. We drill small access holes through the exterior stucco or interior drywall, blow the material into each stud bay at controlled density, then patch and texture the holes so they disappear. Estimates are free.
Brands We Service in Pomona
We install and service insulation from eight major manufacturers, including Owens Corning, Johns Manville, Knauf, and GreenFiber. Because we stock all of them, we’re choosing the right material for your Pomona home, not the one material our supplier happens to have on the truck. Most products are available without a special order, so your install doesn’t stall waiting on a freight shipment. See our brands for the full lineup.

What Pomona Customers Say
"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
— Miguel Flores"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."
— Nia Robinson"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Mark Schaefer
