Insulation Company in Long Beach, CA
Blown in insulation solves a problem Long Beach homeowners know well: rooms that won’t hold temperature once the marine layer rolls in, and attics that feel damp long after the fog burns off. Our team has worked in Long Beach’s 1920s bungalows and post-war tract homes since 2011, and the job here is rarely just about adding R-value. It’s about air sealing old framing, managing moisture in tight attic spaces, and choosing a material that won’t settle or absorb the salt-heavy humidity that sits over ZIP codes 90810 through 90815 for months at a time. Call (855) 382-3925 when you’re ready to talk through what your house actually needs.
Why Long Beach Homes Are Different
Long Beach’s housing stock runs older than most Southern California cities, and that changes how insulation gets installed. The 1920s and 1930s bungalows in neighborhoods like Belmont Heights and Rose Park were built with balloon framing, minimal sheathing, and no insulation in the walls at all. Post-WWII tract homes in East Long Beach and Los Altos got a thin layer of fiberglass in the attic, often R-11 or less, and it’s usually compressed, rodent-damaged, or simply gone by now. Raised foundations are common, which means crawl space air moves up through wall cavities and into the attic, carrying moisture with it.
Then there’s the marine layer. Long Beach sits close enough to the water that May gray and June gloom aren’t a two-week inconvenience; they’re a seasonal climate pattern. Attics that lack proper ventilation collect condensation on the underside of roof decking during those months. Insulation that absorbs that moisture loses its thermal performance and becomes a mold risk. Salt air adds another layer: metal fasteners, insulation supports, and vent screens corrode faster near the coast than they do ten miles inland. The work here isn’t just filling cavities. It’s choosing materials that dry out quickly, sealing air leaks that pull damp air upward, and making sure ventilation moves enough air to keep the attic dry year-round.
Our Main Long Beach Services
Most Long Beach homeowners reach out about two things: an attic that’s cooking the upstairs rooms in summer or letting heat escape in winter, and air leaks that spray foam seals better than anything else. Here’s what each job involves in this city.
Attic Insulation in Long Beach
Long Beach attics run hot and damp, and older homes often have a patchwork of original insulation, homeowner additions, and empty bays. We pull out what’s failed, air seal the top plates and penetrations, and install fresh material suited to the house: blown-in fiberglass or cellulose for most attics, mineral wool where fire resistance matters. The goal is a consistent thermal boundary between the living space and the attic, which matters more here than R-value alone because humidity amplifies any air leak. See Attic Insulation in Long Beach for the full breakdown of this service.
Spray Foam Insulation in Long Beach
Spray foam earns its cost in Long Beach when a house has odd framing, ductwork in the attic, or rooms that never hold temperature no matter what’s been tried. Closed-cell foam from Icynene or Demilec acts as an air barrier, a vapor barrier, and insulation in one pass, which matters in a climate where moist air is the real enemy. We apply it to rim joists, crawl space walls, and attic rooflines where traditional batts would sag or trap condensation. The Spray Foam Insulation in Long Beach page covers the method, the materials, and what it costs to have it done right.

Blown In Insulation in Long Beach
Blown in insulation is the most common retrofit for Long Beach homes built between the 1920s and the 1970s, because it fills wall cavities and attic floors without tearing out drywall or plaster. The material we blow in, whether GreenFiber cellulose or loose-fill fiberglass, settles into odd framing bays and around old wiring in a way batt insulation can’t. In Long Beach’s humid marine layer, blown in cellulose has a second job: it manages moisture better than fiberglass batts because it’s denser and slows air movement through the attic floor, which reduces the condensation that forms on cool surfaces during May gray and June gloom. You can read more about the method itself on our Blown In Insulation page, but the long and short of it for Long Beach is this: blown in insulation closes the gaps that older homes are full of.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to below the top of the ceiling joists, or you can feel air moving around outlet covers and baseboards on exterior walls.
What it costs in Long Beach
Blown in cellulose in Long Beach typically runs $1.20 to $2.30 per square foot installed, depending on depth and access.
How we do it
We air seal the attic floor, net or dam the bays where needed, and blow GreenFiber cellulose to the target depth with a calibrated machine, then check density with a core sample.
Blown In Attic Insulation
Signs you need it
Upstairs rooms run noticeably warmer than downstairs in summer, or your attic has bare spots and thin patches from old material that’s been disturbed by rodents or storage.
What it costs in Long Beach
Blown in attic insulation in Long Beach costs $1.10 to $2.10 per square foot for most homes, with older bungalows running toward the higher end because we spend more time air sealing first.
How we do it
We remove or top off the existing material, seal bypasses and top plates, install baffles at the eaves so soffit vents stay open, and blow loose fill to a consistent depth across the attic floor.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Blown in attic insulation (blow over existing) | $0.80 – $1.50 per sq ft |
| Blown in attic insulation (remove and reinstall) | $1.50 – $3.00 per sq ft |
| Blown in wall insulation (drill and fill) | $2.00 – $4.50 per sq ft of wall |
Prices in Long Beach shift with attic access, how much old material has to come out first, and whether we’re drilling walls from inside or outside. Every estimate is line-item and confirmed before work starts, so the number you approve is the number you pay.
How long does blown in insulation last in Long Beach’s humidity?
Blown in insulation lasts 20 to 30 years or more in Long Beach if the attic is properly ventilated. Humidity shortens its life only when air leaks carry moisture into the material and it stays damp, which is why we air seal before we blow. Call (855) 382-3925 and we’ll check your attic’s ventilation as part of the estimate.
Can blown in insulation be added on top of old insulation in Long Beach?
Yes, in most Long Beach attics we can blow new material over old fiberglass as long as it’s dry and not moldy. If the old insulation is damp from marine layer condensation or roof leaks, it has to come out first or the moisture just transfers. Call (855) 382-3925 and we’ll tell you what your attic needs.

What Long Beach Customers Say
"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Miguel Guzman"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Jason Hoffman"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."
