Insulation Company in Long Beach, CA
Blown in insulation is the most common retrofit we install in Long Beach, and it’s usually the fastest way to fix rooms that bake in the afternoon sun or feel damp all winter. The older bungalows and 1950s stucco tract homes here were rarely insulated to begin with, and what little material exists has usually settled or degraded decades ago. If you’re tired of uneven temperatures between your living room and bedroom, call us at (855) 795-2118. We’ll tell you what’s actually inside your walls and what it’ll take to fix it.
Why Long Beach Homes Are Different
Long Beach sits right in the marine layer belt, which means insulation here is as much about controlling condensation and coastal damp as it is about heat. Homes in the shore-adjacent ZIPs like 90802 and 90803 stay cool and humid most of the year, while places further north and east – 90805, 90810, 90813 – bake through July and August. The same house two miles apart needs a different insulation spec, and we spec accordingly.
The housing stock makes this even more specific. Long Beach has thousands of 1920s through 1940s California bungalows and Spanish stucco homes near downtown and Belmont Shore, plus a huge belt of post-WWII 1950s and 1960s tract houses and stucco duplexes across the north and east sides. Most of those stucco-over-wood-frame walls have little or no cavity insulation. Attics from the knob-and-tube era are under-insulated by modern standards. On the older bungalows, we routinely find wall cavities with no insulation at all, just degraded aluminum-foil or kraft paper that’s been soaking up marine humidity for seventy years. Adding blown-in insulation without a vapor strategy can trap that moisture against the stucco, so air-sealing and ventilation always come first on these jobs.
There’s also a large multi-family rental base in Long Beach where property owners want quick payback through noise and moisture control rather than heating savings. Blown-in cellulose and fiberglass handle both well when installed with the right density.
Our Main Long Beach Services
Most Long Beach homeowners call us about two things: an attic that’s letting heat pour in during summer and walls that were never insulated to begin with. Here’s how those jobs work here.
Attic Insulation in Long Beach
Attics in Long Beach collect heat all afternoon, and in older homes that heat radiates down into bedrooms until well past midnight. We see a lot of 1950s and 1960s tract houses with maybe three inches of settled fiberglass in the attic – nowhere near what today’s climate calls for. It’s also common to find no air sealing at all around light fixtures, plumbing penetrations, and the attic hatch, which lets humid marine air circulate into unconditioned space. Condensation on the underside of roof decking is a problem we diagnose regularly in coastal Long Beach. The fix starts with identifying your home’s specific condition, then matching the right material and depth. For the full breakdown, see our Attic Insulation in Long Beach page.

Spray Foam Insulation in Long Beach
Spray foam earns its keep in Long Beach when there’s a moisture or air-sealing challenge that batts and blown-in material can’t fully solve, and when you want to turn a vented attic into conditioned space. On stucco homes near the coast, closed-cell foam’s vapor barrier properties matter more than its R-value. Inland, where summer heat dominates, open-cell foam on the roofline stops the thermal gain before it starts. We install both Icynene and Demilec systems, so the recommendation follows the house, not our inventory. Read more on our Spray Foam Insulation in Long Beach page.

Blown In Insulation in Long Beach
Blown in insulation is the most practical retrofit for Long Beach’s older wall cavities, because it can be installed through small access holes without tearing out drywall or stucco. For the bungalows and tract homes that make up most of this city, that means we can fill empty or under-filled wall and attic cavities with minimal disruption. Whether you choose GreenFiber cellulose or Johns Manville fiberglass, the goal is the same: stop the heat gain and damp air movement that make these older Long Beach homes uncomfortable. This is the core of what we do, and you can read more about the method on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Rooms that stay cold in winter despite the heat running, or upstairs rooms that stay hot well after sunset, often point to settled or missing insulation in the walls and attic.
What it costs in Long Beach
Expect to pay between $1.10 and $2.80 per square foot for blown-in cellulose in Long Beach, depending on density and depth.
How we do it
We drill small access holes in each stud bay, blow in the cellulose at the right density using a calibrated machine, then patch and texture the holes to match.
Blown In Attic Insulation
Signs you need it
An attic floor with less than six inches of insulation, or insulation that’s visibly compressed and dark with dust, is doing very little to stop heat from radiating down into your home.
What it costs in Long Beach
Attic blow-in typically runs between $1.00 and $2.50 per square foot in Long Beach, with deeper R-value upgrades landing at the higher end.
How we do it
We air-seal the attic floor penetrations first, then blow the material to a level, measured depth that achieves the R-value the home needs.
Blown In Cellulose Insulation
Signs you need it
Homes built before 1980 in Long Beach usually have either no wall insulation or a thin layer that’s settled, leaving the top third of every wall empty.
What it costs in Long Beach
Blown-in cellulose for wall cavities or attic floors ranges from $1.10 to $2.80 per square foot in Long Beach depending on wall density and access.
How we do it
We use a dense-pack method for walls to prevent settling and maximize air movement resistance, and a loose-fill method for open attic floors.
Blown In Fiberglass Insulation
Signs you need it
If your attic has old, thin fiberglass batts that are torn or displaced, blowing in new fiberglass over and around them is an affordable way to restore full coverage.
What it costs in Long Beach
Blown-in fiberglass runs between $1.00 and $2.00 per square foot in Long Beach, making it one of the lower-cost attic upgrades available.
How we do it
We remove or level the old material as needed, blow the fiberglass to a consistent depth, and measure the final R-value before we leave.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Blown-in fiberglass (attic) | $1.00 – $2.00 per sq ft |
| Blown-in cellulose (attic) | $1.10 – $2.80 per sq ft |
| Blown-in cellulose (walls, dense pack) | $1.10 – $2.80 per sq ft |
How long does blown in insulation take in Long Beach?
Most Long Beach homes are done in one day, including wall access holes and attic coverage. Larger attics or dense-pack wall jobs can run into a second morning, but we’ll tell you the schedule before we start.
Can you insulate old Long Beach walls without opening them up?
Yes. We access wall cavities through small exterior or interior holes, blow in the material, and patch to match. That’s why blown in insulation is the standard retrofit for Long Beach stucco homes.
Brands We Service in Long Beach
We install Owens Corning, Johns Manville, Knauf, and Rockwool – brands with documented R-value performance data, not private-label unknowns. Long Beach jobs get the material that matches the house: Rockwool where fire resistance and sound control matter, Owens Corning or Johns Manville where R-value per inch is the priority, Knauf for a proven fiberglass option. Most materials are available within a few days. See our brands for the full lineup.

Marine humidity also means we sometimes add air-sealing or a vapor strategy that a drier climate wouldn’t need.

What Long Beach 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."
— Mark Hoffman"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Keisha Jackson"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Danielle Schaefer
