Insulation Company in Whittier, CA
Blown in insulation solves the single most common comfort problem we see in Whittier homes: rooms that never hold temperature because the attic never had enough material to begin with. Most houses here were built between the 1920s and 1970s, and most have attics with thin, settled, or missing insulation. We’re Even Air Insulation, and we’ve served Whittier since 2018, matching the right material – cellulose, fiberglass, mineral wool, or spray foam – to each house rather than pushing one product.

Why Whittier Homes Are Different
Whittier is an older, largely built-out San Gabriel Valley suburb. Walk the streets near uptown and you’ll see California bungalows and Spanish Colonial Revival homes from the 1920s and 1930s – beautiful houses, built before modern insulation was even a code requirement. Head south or east into the 90602 through 90606 ZIPs and you’ll find the post-war ranch tracts from the 1950s and 1960s, slightly newer but rarely much better insulated. Almost everything here predates Title 24 energy standards, which means insulation work in Whittier is overwhelmingly retrofit: blowing material into existing attics and walls rather than installing it during construction.
The terrain matters too. Whittier spans distinct micro-markets, from the hotter, wind-exposed hillside edges and Friendly Hills area above the valley floor to the flatter, older tracts near uptown and the 90601 corridors. The hillside homes face punishing sun exposure and Santa Ana wind conditions that the valley floor homes don’t. And many of the older Whittier homes still have knob-and-tube or early romex wiring in the walls, which complicates any wall-blowing work. A house on a shaded street near uptown performs very differently from one on a sun-blasted Friendly Hills slope, even if they were built the same year.
Our Main Whittier Services
Whittier homeowners call us most about two services: attic insulation and spray foam insulation. Each has its own detailed page below.
Attic Insulation in Whittier
Attic insulation is the highest-return energy upgrade most Whittier homes can make. In a cooling-dominated climate like this one, the attic is where radiant heat builds up all afternoon and pushes down into living spaces. The fix is adding depth to what’s already there – usually blown in cellulose or fiberglass over old batts – after checking air sealing. The older homes near uptown often have attics with original vents and no baffles, so we build those in before adding material. For the full breakdown of attic work in Whittier, see Attic Insulation in Whittier.
Spray Foam Insulation in Whittier
Spray foam isn’t always the answer – but when it is, we have two professional-grade options through Icynene and Demilec. In Whittier, closed-cell foam earns its keep in hillside homes where wind-driven dust and moisture intrusion are real problems, and in wall cavities around old knob-and-tube wiring where loose fill can’t go. Open-cell foam works well for attic rooflines where you want air sealing and thermal resistance together. We carry both, so the recommendation depends on the house, not our inventory.

Blown In Insulation in Whittier
Blown in insulation is the backbone of retrofit work in Whittier, because most homes here were built with either nothing in the attic or a thin layer that’s settled to near zero R-value. Summers are hot and dry in the San Gabriel Valley, and the sun beats on older roofs all afternoon, so attics turn into ovens and that heat pushes down into bedrooms and living rooms. Blowing insulation into the attic is the fastest, least disruptive way to fix that. We use GreenFiber cellulose and professional fiberglass from Owens Corning and CertainTeed, matched to the existing attic conditions, including older homes where knob-and-tube wiring means we plan carefully before blowing around it. Learn more about the method on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Rooms directly under the attic run 10 to 15 degrees hotter than the rest of the house on summer afternoons, and you can feel the ceiling radiating heat after the sun goes down.
What it costs in Whittier
Cellulose insulation in Whittier typically runs $1.10 to $1.60 per square foot depending on depth and access, with a two-bedroom ranch in the 90603 area often landing between $1,600 and $2,400 total.
How we do it
We air-seal the attic floor penetrations first, then dense-pack or loose-blow GreenFiber cellulose to the target R-value, keeping it clear of old wiring and knee walls.
Blown In Attic Insulation
Signs you need it
Your attic floor shows bare spots or batts that are yellowed, compressed, and sitting below the tops of the joists.
What it costs in Whittier
Blown in attic insulation in Whittier generally costs $1.30 to $2.70 per square foot, which puts a standard 1,200-square-foot attic at roughly $1,600 to $2,900 before any air sealing.
How we do it
We remove or level the old material if needed, install baffles at the eaves so vents stay clear, then blow fiberglass or cellulose to a consistent depth across the attic floor.
Blown In Cellulose Insulation
Signs you need it
Your energy bill spikes every July through September, and the attic floor insulation looks thin enough to see the drywall seams below it.
What it costs in Whittier
Blown in cellulose insulation in Whittier costs from $1.10 to $1.60 per square foot, so a 1,500-square-foot attic typically lands between $1,700 and $2,700.
How we do it
We treat the attic floor for air leaks around pipes, wires, and top plates, then blow GreenFiber cellulose to the depth required for R-38 or R-44 in this climate.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old fiberglass batts that are compressed and dusty, and you want to increase R-value without disturbing the existing wiring or ductwork.
What it costs in Whittier
Blown in fiberglass insulation in Whittier runs $1.10 to $2.90 per square foot, so a standard attic here usually totals between $1,800 and $3,200 depending on depth and access.
How we do it
We blow loose-fill fiberglass over existing batts to hit the target R-value, using a machine that fluffs the material for consistent coverage and no settling.
Loose Fill Insulation
Signs you need it
You have open wall cavities after a remodel, or an attic with tight corners and irregular joist spacing where batts would leave gaps.
What it costs in Whittier
Loose fill insulation in Whittier costs from $1.10 to $2.90 per square foot depending on whether it’s blown into walls or an attic, with wall jobs typically running $2.20 to $3.40 per square foot once site prep is included.
How we do it
We drill clean access holes where needed, blow the loose fill into each cavity at the right density, then patch the holes and clean up the work area.
What Blown In Insulation Costs in Whittier
| Item | Typical range in Whittier |
|---|---|
| Cellulose attic insulation | $1.10 – $1.60 per sq ft |
| Fiberglass attic insulation | $1.30 – $2.90 per sq ft |
| Wall cavity loose fill | $2.20 – $3.40 per sq ft |
Prices in Whittier shift with the age of the house. Older homes with knob-and-tube wiring or no existing baffles take more prep time, and hillside attics with tight access push labor up. We give upfront pricing before any work starts.
Is blown in insulation worth it in Whittier?
Yes. In Whittier’s cooling-dominated climate, a properly insulated attic can cut summer cooling costs noticeably and makes upstairs rooms comfortable for the first time in the life of the house. Call (855) 362-0195 for an estimate.
Can you install blown in insulation in older Whittier homes?
Yes, and most of the blown in work we do in Whittier is in homes from the 1920s through 1970s. The key is checking for knob-and-tube wiring first, then air-sealing before any material goes in.
Brands We Service in Whittier

What Whittier 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."
— Emily Gallagher"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Luis Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
